The embodiments described below with reference to the accompanying drawings are examples, and are intended to explain this application, but shall not be understood as a limitation on this application.

     As shown in  FIG.  1    to  FIG.  24   , a heat exchange apparatus according to embodiments of this application includes a heat exchanger  10 , a refrigerant adjustment component  20 , and a first connecting member  30 . 
     The heat exchanger  10  includes a first pipe  1 , a second pipe  2 , and a plurality of heat exchange tubes  3 . The first pipe  1  and the second pipe  2  are arranged spaced apart. As shown in  FIG.  1   , the first pipe  1  and the second pipe  2  are spaced apart in a front-rear direction. Specifically, the first pipe  1  and the second pipe  2  are arranged roughly in parallel. As shown in  FIG.  1    and  FIG.  14   , both the first pipe  1  and the second pipe  2  roughly extend in a left-right direction. In other words, both a length direction of the first pipe  1  and a length direction of the second pipe  2  are the left-right direction. 
     The plurality of heat exchange tubes  3  are arranged spaced apart in the length direction of the first pipe  1 . As shown in  FIG.  1    and  FIG.  14   , the plurality of heat exchange tubes  3  are arranged spaced apart in the left-right direction. 
     The heat exchanger  10  further includes an edge plate  4 , and the edge plate  4  is located on an outer side of the plurality of heat exchange tubes  3  in the length direction of the first pipe  1 . It should be noted herein that a direction toward a center position in the length direction of the first pipe  1  is inward, and a direction away from the center position in the length direction of the first pipe  1  is outward. Specifically, there are at least two edge plates  4 , one of the edge plates  4  is located on a rightmost side of the plurality of heat exchange tubes  3 , and another edge plate  4  is located on a leftmost side of the plurality of heat exchange tubes  3 . 
     At least part of the refrigerant adjustment component  20  is located on an outer side of the edge plate  4  in the length direction of the first pipe  1 . In other words, the refrigerant adjustment component  20  is arranged on a side, away from the plurality of heat exchange tubes  3 , of the edge plate  4 . Specifically, the refrigerant adjustment component  20  may be located on a left side of a left edge plate, and/or on a right side of a right edge plate  4 . 
     The refrigerant adjustment component  20  includes a cavity for accommodating refrigerant and an outer wall enclosing the cavity. The outer wall of the refrigerant adjustment component  20  has an opening for refrigerant flow. An included angle between an axis in a length direction of at least part of the outer wall of the refrigerant adjustment component  20  and an axis in the length direction of the first pipe  1  is greater than 0° and less than or equal to 90°. 
     The first connecting member  30  communicates the opening of the refrigerant adjustment component  20  and the first pipe  1 , and in a direction of gravity, the opening of the refrigerant adjustment component  20  is higher than a communication position between the first connecting member  30  and the first pipe  1 . Specifically, one end of the first connecting member  30  is connected to the opening of the refrigeration adjustment component  20 , and the other end of the first connecting member  30  is communicated with the first pipe  1 . The other end of the first connecting member  30  may be directly communicated with the first pipe  1 , and in this case, the opening of the refrigerant adjustment component  20  is higher than the communication position between the other end of the first connecting member  30  and the first pipe  1 . Alternatively, an end of the first pipe  1  in the length direction is connected to an inlet/outlet pipe  5 , and the inlet/outlet pipe  5  is communicated with the other end of the first connecting member  30 . In this case, the opening of the refrigerant adjustment component  20  is higher than a communication position between the other end of the first connecting member  30  and the inlet/outlet pipe  5 . 
     In a heat pump system, that a volume of an outdoor heat exchanger is greater than that of an indoor heat exchanger is used as an example. When the heat pump system switches from a cooling mode to a heating mode, the indoor heat exchanger serves as a condenser. Injection space of the indoor heat exchanger is limited. Therefore, according to the heat exchange apparatus in this application, the refrigerant adjustment component  20  communicated with the first pipe  1  through the first connecting member  30  is disposed on the outer side of the edge plate  4  in the length direction of the first pipe  1 . The included angle between the axis in the length direction of the at least part of the outer wall of the refrigerant adjustment component  20  and the axis in the length direction of the first pipe  1  is greater than 0° and less than or equal to 90°. Excess refrigerant enters the refrigerant adjustment component  20  communicated with the heat exchanger  10 , and excess liquid refrigerant is stored by using the refrigerant adjustment component  20 , to improve an operating capability of the heat pump system. When the heat pump system switches from the heating mode to the cooling mode, the indoor heat exchanger serves as an evaporator, and the heat pump system needs more refrigerant to improve heat exchange efficiency. In this case, in the direction of gravity, the opening of the refrigerant adjustment component  20  is higher than the communication position between the first connecting member  30  and the first pipe  1 , and liquid refrigerant in the refrigerant adjustment component  20  flows into the heat exchanger  10  because of gravity of the liquid refrigerant to participate in heat exchange of the heat pump system, so as to improve heat exchange performance. In this way, the heat exchange apparatus according to the embodiments of this application is used as a smaller-volume heat exchanger, so that when the heat pump system switches between the cooling mode and the heating mode, refrigerant in the heat pump system can be compensated and adjusted. Therefore, an amount of exchanged heat and an energy efficiency ratio on the indoor side are stabilized in both the cooling mode and the heating mode, thereby improving efficiency of the heat pump system. 
     In some specific embodiments, as shown in  FIG.  15    to  FIG.  24   , the plurality of heat exchange tubes  3  are arranged in parallel, and each heat exchange tube  3  extends in an up-down direction, so that the heat exchanger  10  is a parallel flow heat exchanger. 
     It can be understood that this application is not limited thereto. In some other embodiments, as shown in  FIG.  1    to  FIG.  13   , the heat exchange tube  3  includes a first straight section  31 , a second straight section  32 , and a connecting section  33 . One end of the first straight section  31  in a length direction of the first straight section  31  is inserted into the first pipe  1  to be communicated with the first pipe  1 , and the other end of the first straight section  31  in the length direction of the first straight section  31  is communicated with one end of the connecting section  33 . One end of the second straight section  32  in a length direction of the second straight section  32  is inserted into the second pipe  2  to be communicated with the second pipe  2 , and the other end of the second straight section  32  in the length direction of the second straight section  32  is communicated with the other end of the connecting section  33 . The connecting section  33  is bent with respect to the first straight section  31  and the second straight section  32 . The first straight section  31 , the connecting section  33 , and the second straight section  32  include a channel, and the channel communicates the first pipe  1  and the second pipe  2 . An included angle between the length direction of the first straight section  31  and the length direction of the second straight section  32  is greater than or equal to 0° and less than 180°. Therefore, the heat exchanger  10  is a bent heat exchanger. 
     Specifically, a lower end of the first straight section  31  is inserted into the first pipe  1  to be communicated with the first pipe  1 , and a lower end of the second straight section  32  is inserted into the second pipe  2  to be communicated with the second pipe  2 . The connecting section  33  connects an upper end of the first straight section  31  and an upper end of the second straight section  32 , and is bent with respect to the first straight section  31  and the second straight section  32 . It should be noted herein that the connecting section  33  may be shown in  FIG.  12    and  FIG.  13   , the connecting section  33  extends in the left-right direction, and the connecting section  33  is communicated with a plurality of first straight sections  31  and communicated with a plurality of second straight sections  32 . It can be understood that this application is not limited thereto. For example, the connecting section  33  may alternatively be a curved section. The curved section may be bent only with respect to the first straight section  31  and the second straight section  32 , as shown in  FIG.  6   . The curved section may alternatively be twisted and bent with respect to the first straight section  31  and the second straight section  32 , as shown in  FIG.  1   . 
     The heat exchange tube  3  includes at least one channel, and the channel extends from the first straight section  31  to the second straight section  32  through the connecting section  33 , so as to communicate the first pipe  1  and the second pipe  2 . The first straight section  31  and the second straight section  32  may be arranged roughly in parallel, for example, both the first straight section  31  and the second straight section  32  extend in the up-down direction. In addition, the length direction of the first straight section  31  and the length direction of the second straight section  32  may have an included angle, and the included angle is greater than 0° and less than 180°. 
     The edge plate  4  includes a first edge plate  41  located on an outer side of first straight sections  31  of the plurality of heat exchange tubes  3  in the length direction of the first pipe  1 , and a second edge plate  42  located on an outer side of second straight sections  32  of the plurality of heat exchange tubes  3  in the length direction of the first pipe  1 . In other words, the outer side of the plurality of first straight sections  31  in the length direction of the first pipe  1  and the outer side of the plurality of second straight sections  32  in the length direction of the first pipe  1  each are provided with the edge plates  4 . It should be noted herein that a direction toward a center position in the length direction of the first pipe  1  is inward, and a direction away from the center position in the length direction of the first pipe  1  is outward. Specifically, there are at least two first edge plates  41 , one of the first edge plates  41  is located on a rightmost side of the plurality of first straight sections  31 , and another first edge plate  41  is located on a leftmost side of the plurality of first straight sections  31 ; there are at least two second edge plates  42 , one of the second edge plates  42  is located on a rightmost side of the plurality of second straight sections  32 , and another second edge plate  42  is located on a leftmost side of the plurality of second straight sections  32 . 
     At least part of the refrigerant adjustment component  20  is located on an outer side of the first edge plate  41  and the second edge plate  42  in the length direction of the first pipe  1 . In other words, the refrigerant adjustment component  20  is arranged on a side, away from the plurality of heat exchange tubes  3 , of the edge plate  4 . Specifically, the refrigerant adjustment component  20  may be located on a left side of a left first edge plate  41  and a left second edge plate  42 , and/or on a right side of a right first edge plate  41  and a right second edge plate  42 . 
     In some embodiments, the edge plate  4  includes a first side surface and a second side surface in the length direction of the first pipe  1 , and the refrigerant adjustment component  20  is connected to at least one of the first side surface and the second side surface of the edge plate  4 . In other words, in this embodiment, the refrigerant adjustment component  20  is mounted on the edge plate  4 . 
     Specifically, in the embodiment shown in  FIG.  14   , the refrigerant adjustment component  20  is mounted on the left edge plate  4 , and may be connected to a left side surface of the left edge plate  4 . It can be understood that this application is not limited thereto. The refrigerant adjustment component  20  may alternatively be connected to a right side surface of the left edge plate  4 . In this case, a dimension of the left edge plate  4  in the front-rear direction perpendicular to the up-down direction and the left-right direction (for example, a width of the left edge plate  4 ) is greater than a dimension of the heat exchange tube  3  in the front-rear direction (which is, for example, when the heat exchange tube  3  is a flat tube, a width of the flat tube), so as to exceed the heat exchange tube  3  in the front-rear direction. The refrigerant adjustment component  20  is connected to a right side surface of a part, exceeding the heat exchange tube  3 , of the left edge plate  4 . 
     When the heat exchanger  10  is a bent heat exchanger, as shown in  FIG.  1    to  FIG.  13   , the length direction of the first straight section  31  is parallel to the length direction of the second straight section  32 . The first edge plate  41  and the second edge plate  42  each include a first side surface and a second side surface in the length direction of the first pipe  1 . The refrigerant adjustment component  20  is connected to at least one of the first side surface and the second side surface of the first edge plate  41 , and/or at least one of the first side surface and the second side surface of the second edge plate  42 . For example, the first straight section  31  and the second straight section  32  are spaced apart in the front-rear direction and are arranged roughly in parallel, the first pipe  1  extends in the left-right direction, and the first edge plate  41  and the second edge plate  42  each include an inner side surface and an outer side surface that are arranged opposite to each other. An inner side surface of the left first edge plate  41 /second edge plate  42  is a right side surface of this first edge plate  41 /second edge plate  42 , and an outer side surface of the left first edge plate  41 /second edge plate  42  is a left side surface of this first edge plate  41 /second edge plate  42 . An inner side surface of the right first edge plate  41 /second edge plate  42  is a left side surface of this first edge plate  41 /second edge plate  42 , and an outer side surface of the right first edge plate  41 /second edge plate  42  is a right side surface of this first edge plate  41 /second edge plate  42 . The refrigerant adjustment component  20  is connected to at least one of the left side surface and the right side surface of the first edge plate  41  and/or at least one of the left side surface and the right side surface of the second edge plate  42 . 
     In some specific embodiments, the refrigerant adjustment component  20  may be connected to the first edge plate  41 /second edge plate  42  on either side of the left side and the right side. Specifically, the refrigerant adjustment component  20  may be all located on the outer side of this first edge plate  41 /second edge plate  42 , and may be connected to the outer side surface of the first edge plate  41  and the outer side surface of the second edge plate  42 ; or may be connected only to the outer side surface of the first edge plate  41 , or only to the outer side surface of the second edge plate  42 . Alternatively, the refrigerant adjustment component  20  may be all located on the inner side of this first edge plate  41  and/or second edge plate  42 , and may be connected to the inner side surface of the first edge plate  41  and the inner side surface of the second edge plate  42 ; or may be connected only to the inner side surface of the first edge plate  41 , or only to the inner side surface of the second edge plate  42 . Alternatively, a part of the refrigerant adjustment component  20  may be located on the outer side of the first edge plate  41  and/or the second edge plate  42 , and the other part is located on the inner side of the first edge plate  41  and/or the second edge plate  42 .

     It can be understood that this application is not limited to a form in which the refrigerant adjustment component  20  is mounted on the edge plate  4 . For example, in some other embodiments, the heat exchange apparatus further includes a mounting member  6 , the mounting member  6  is disposed on an outer side of the edge plate  4  in the length direction of the first pipe  1 , and the refrigerant adjustment component  20  is fixedly connected to the mounting member  6 .

     Specifically, the mounting member  6  may be disposed only on an outer side of the first edge plate  41  and the second edge plate  42  on either side of the left side and the right side of the heat exchanger  10 . In this case, the refrigerant adjustment component  20  is disposed only on this side of the heat exchanger  10 , and as shown in  FIG.  1    to  FIG.  5   , the refrigerant adjustment component  20  is disposed only on the right side of the right first edge plate  41  and second edge plate  42 . Alternatively, the mounting member  6  may be disposed on an outer side of the first edge plate  41  and the second edge plate  42  on each side of the left side and the right side of the heat exchanger  10 . In this case, refrigerant adjustment components  20  may be disposed on both the left and right sides of the heat exchanger  10 , as shown in  FIG.  10   .

The refrigerant adjustment component  20  may be connected to the inner side surface of the mounting member  6 , or may be connected only to the outer side surface of the mounting member  6 .

     The arrangement position of the refrigerant adjustment component  20  in this application is not limited to those shown in  FIG.  1    to  FIG.  5   ,  FIG.  8   , and  FIG.  10   . For example, in some other specific embodiments, the refrigerant adjustment component  20  includes a plurality of adjustment members  21 , at least one adjustment member  21  is connected to the first side surface of the mounting member  6 , and at least another adjustment member  21  is connected to the second side surface of the mounting member  6 . In other words, the refrigerant adjustment component  20  includes the adjustment member  21  located on the outer side of the mounting member  6  and is connected to the outer side surface of the mounting member  6 , and further includes the adjustment member  21  located on the inner side of the mounting member  6  and is connected to the inner side surface of the mounting member  6 . The adjustment member  31  located on the inner side of the mounting member  6  is located in inner space between the plurality of first straight sections  31  and the plurality of second straight sections  32 .

The adjustment members  21  mounted on both the left and right sides of the mounting member  6  can save installation space, and the adjustment member  21  can exchange heat with intake air, to improve use efficiency. 
     In some embodiments, the refrigerant adjustment component  20  includes a plurality of adjustment members  21 , and every two of at least two adjustment members  21  are communicated with each other. The plurality of adjustment members  21  include a first adjustment member  211 . The first adjustment member  211  includes a cavity for accommodating refrigerant and an outer wall enclosing the cavity, and the outer wall of the first adjustment member  211  has an opening for refrigerant flow. There is one first connecting member  30 . The opening of the first adjustment member  211  is communicated with the first pipe  1  through the first connecting member  30 , and in the direction of gravity, the opening of the first adjustment member  211  is higher than the communication position between the first connecting member  30  and the first pipe  1 . 
     Specifically, the opening of only the first adjustment member  211  in the plurality of adjustment members  21  is communicated with the first pipe  1  through the first connecting member  30 , the first adjustment member  211  is communicated with one of the remaining adjustment members  21 , and every two of the remaining adjustment members  21  are communicated with each other, so that the plurality of adjustment members  21  are connected in series and then communicated with the first pipe  1  through the first connecting member  30 , as shown in  FIG.  1    to  FIG.  7   . 
     In the embodiments shown in  FIG.  1    to  FIG.  5   , there are two adjustment members  21 , the two adjustment members  21  are arranged spaced apart in the front-rear direction, and the front adjustment member  21  is a first adjustment member  211 . An outer wall of the first adjustment member  211  is provided with two openings, and an outer wall of the rear adjustment member  21  is provided with one opening. One opening of the first adjustment member  211  is communicated with the first pipe  1  through the first connecting member  30 , and the other opening of the first adjustment member  211  is communicated with the opening of the rear adjustment member  21  through a second connecting member  40 , so that the two adjustment members  21  are arranged in series. 
     In the embodiments shown in  FIG.  6   ,  FIG.  7   ,  FIG.  12   , and  FIG.  13   , there are three adjustment members  21 , the three adjustment members  21  are arranged spaced apart in the front-rear direction, and the front adjustment member  21  of the three adjustment members  21  is a first adjustment member  211 . An outer wall of the first adjustment member  211  is provided with two openings, an outer wall of the middle adjustment member  21  is provided with two openings, and an outer wall of the rear adjustment member  21  is provided with one opening. One opening of the first adjustment member  211  is communicated with the first pipe  1  through the first connecting member  30 , the other opening of the first adjustment member  211  is communicated with one opening of the middle adjustment member  21  through one second connecting member  40 , and the other opening of the middle adjustment member  21  is communicated with the opening of the rear adjustment member  21  through another second connecting member  40 , so that the three adjustment members  21  are arranged in series. The adjustment members  21  arranged in series can more flexibly adjust an amount of refrigerant in a system when a working condition changes, especially in the frequency conversion system, and can adapt to various working conditions. 
     It can be understood that this application is not limited to the foregoing series connection. For example, among the plurality of adjustment members  21 , in addition to that the opening of the first adjustment member  211  is communicated with the first pipe  1  through the first connecting member  30 , at least one adjustment member  21  of the remaining adjustment members  21  is communicated with the first pipe through a connecting member. In addition, every two of the plurality of adjustment members  21  are communicated, so as to implement a plurality of combination forms of series and parallel connections. 
     In some embodiments, the refrigerant adjustment component  20  includes a plurality of adjustment members  21 , and the plurality of adjustment members  21  each include a cavity for accommodating refrigerant and an outer wall enclosing the cavity. An outer wall of the adjustment member  21  has an opening for refrigerant flow. Openings of the plurality of adjustment members  21  are all communicated with the first pipe  1  through the first connecting member  30 , and in the direction of gravity, the opening of each adjustment member  21  is higher than the communication position between the first connecting member  30  and the first pipe  1 . In other words, when the heat pump system is switched from the cooling mode to the heating mode, refrigerant in the first pipe  1  may separately flow into the plurality of adjustment members  21  through the first connecting member  30 , and when the heat pump system is switched from the heating mode to the cooling mode, refrigerant in the plurality of adjustment members  21  may all fall back into the first pipe  1  due to gravity, so as to implement a form of parallel connection of the plurality of adjustment members  21 . Each adjustment member  21  may independently adjust a flow amount of refrigerant, which further helps refrigerant flow, thereby improving efficiency of the heat pump system. 
     There are a plurality of arrangement forms of the first connecting member  30 . For example, in some specific embodiments, there are a plurality of first connecting members  30 , each of the adjustment members  21  corresponds to one first connecting member  30 , and each of the adjustment members  21  is communicated with the first pipe  1  through a corresponding first connecting member  30 . For example, in some other specific embodiments, there is one first connecting member  30 , and the plurality of adjustment members  21  are integrally formed and are communicated with the first pipe  1  through the first connecting member  30 , as shown in  FIG.  15   . 
     In some embodiments, the adjustment member  21  is an adjustment pipe, and a hydraulic diameter of the adjustment pipe is greater than 0.5 times of a hydraulic diameter of the first pipe  1  and less than 2 times of the hydraulic diameter of the first pipe  1 . Therefore, an amount of exchanged heat and an energy efficiency ratio in different modes are further stabilized, thereby improving efficiency of the heat pump system. 
     In some embodiments, a volume of the refrigerant adjustment component  20  is greater than 0.25 times of a volume of the first pipe  1  and less than 5 times of the volume of the first pipe  1 , so as to further stabilize an amount of exchanged heat and an energy efficiency ratio on the indoor side in different modes, thereby improving efficiency of the heat pump system. 
     In some embodiments, the heat exchanger  10  further includes fins  7 , and the fins  7  are disposed between adjacent heat exchange tubes  3 , to increase a heat exchange area of two adjacent heat exchange tubes  3 , thereby improving heat exchange efficiency of the heat exchanger  10 . 
     Specifically, when the heat exchanger  10  is a bent heat exchanger, the fins  7  are disposed between adjacent first straight sections  32  and between adjacent second straight sections  32 , and no fins  7  are disposed adjacent bent sections  33 . 
     The following describes, with reference to  FIG.  25   , a heat pump system including the heat exchange apparatus according to the embodiment of this application. 
     The heat pump system includes a compressor  100 , a flow direction switching member  200 , a first heat exchanger  300 , a throttle member  400 , a second heat exchanger  500 , and a controller  600 . The compressor  100 , the first heat exchanger  300 , and the second heat exchanger  500  each include a first opening and a second opening. The first opening of the first heat exchanger  300  is communicated with the first opening of the compressor  100  through the flow direction switching member  200 , and the second opening of the first heat exchanger  300  is communicated with the first opening of the throttle member  400 . The first opening of the second heat exchanger  500  is communicated with the second opening of the throttle member  400 , and the second opening of the second heat exchanger  500  is communicated with the second opening of the compressor  100  through the flow direction switching member  200 . Specifically, adjacent apparatus in the heat pump system are communicated at least through a pipe. 
     When the heat pump system works, the system is filled with refrigerant, and the refrigerant may circulate in the heat pump system. Driven by the controller  600 , the flow direction switching member  200  is configured to change a flow direction of the refrigerant in the heat exchange system. In other words, under the action of the flow direction switching member  200 , the refrigerant may flow out from the compressor  100 , first pass through the first heat exchanger  300  and then the second heat exchanger  500 , and then flow back to the compressor  100 ; or may flow out from the compressor  100 , first pass through the second heat exchanger  500  and then the first heat exchanger  300 , and then flow back to the compressor  100 . 
     At least one of the first heat exchanger  300  and the second heat exchanger  500  is the heat exchange apparatus according to the embodiment of this application. Therefore, the first heat exchanger  300  and/or the second heat exchanger  500  can accommodate more refrigerant, to adjust an amount of refrigerant working in a system, thereby improving system efficiency.
