It should be understood that the objects identified as "first\second\third" may be interchangeable under appropriate circumstances such that the exemplary embodiments of the disclosure described herein may be implemented in an order other than those illustrated or described herein.

The heat dissipation structure according to the exemplary embodiments of the present disclosure will be described in detail below with reference to <FIG>.

As shown in <FIG>, an exemplary embodiment of the present disclosure provides an electronic device and a heat dissipation structure. The heat dissipation structure includes a first body <NUM>, a second body <NUM>, a heat dissipation member <NUM> and a connection member <NUM>. A first end of the connection member <NUM> is fixedly connected to the first body <NUM>, and a second end of the connection member <NUM> is fixedly connected to the second body <NUM>. The heat dissipation member <NUM> is disposed in the middle of the connection member <NUM>, and is located between the first body <NUM> and the second body <NUM>. Each one of the first body <NUM> and the second body <NUM> has a distance, which is within a preset distance range, from the heat dissipation member <NUM>; or, a preset distance is provided between the heat dissipation member <NUM> and each one of the first body <NUM> and the second body <NUM>.

In an exemplary embodiment of the present disclosure, shapes of the first body <NUM> and the second body <NUM> are not limited. Each of the first body <NUM> and the second body <NUM> exemplarily shown in <FIG> has a plate-like structure.

Here, the first body <NUM> and the second body <NUM> are only broadly referred to and do not particularly limit which part thereof is. For example, as shown in <FIG>, the first body <NUM> may be a mother board, which may include a Printed Circuit Board (PCB) and a mother board chip <NUM>. For another example, the second body <NUM> may be a daughter board, which may include a PCB board and a daughter board chip <NUM>.

In an exemplary embodiment of the present disclosure, the structure of the connection member <NUM> is not limited, as long as the connection member <NUM> has a first end fixedly connected to the first body <NUM> and a second end fixedly connected to the second body <NUM>; and the heat dissipation member <NUM> is disposed in the middle of the connection member <NUM>. For example, the connection member <NUM> may include a bolt and a nut, via which the first body <NUM> and the second body <NUM> are fixedly connected, and the heat dissipation member <NUM> is disposed in the middle of the bolt.

Here, the number of the connection members <NUM> is not limited, and <FIG> and <FIG> exemplarily show four connection members <NUM>.

In an exemplary embodiment of the present disclosure, the heat dissipation member <NUM> is used for dissipating heat from at least one of the first body <NUM> and the second body <NUM>, and the specific structure thereof is not limited as long as each one of the first body <NUM> and the second body <NUM> has a distance, which is within a preset distance range, from the heat dissipation member <NUM>; or, a preset distance is provided between the heat dissipation member <NUM> and each one of the first body <NUM> and the second body <NUM>.

Those of ordinary skill in the art may set the preset distance according to actual needs, as long as the preset distance satisfies the condition that the heat dissipation member <NUM> can dissipate heat from at least one of the first body <NUM> and the second body <NUM>. Here, it should be understood that, the heat dissipation member <NUM> is disposed in the middle of the connection member <NUM>. Those of ordinary skill in the art may set the preset distance range according to actual needs, as long as the preset distance range satisfies the condition that the heat dissipation member <NUM> can dissipate heat from at least one of the first body <NUM> and the second body <NUM>. Here, it should be understood that, the heat dissipation member <NUM> is movable in the middle of the connection member <NUM>, such that each one of the first body <NUM> and the second body <NUM> has a distance, which is within a preset distance range, from the heat dissipation member <NUM>.

In some implementations of the present disclosure, in order to enable the heat dissipation member <NUM> to better dissipate heat from at least one of the first body <NUM> and the second body <NUM>, a heat-conducting medium is disposed between the heat dissipation member <NUM> and at least one of the first body <NUM> and the second body <NUM>, via which heat can be better transferred, thereby improving the heat dissipation efficiency.

For example, when at least one of the first body <NUM> and the second body <NUM> has a distance, which is within the preset distance range, from the heat dissipation member <NUM>, the heat dissipation structure may further include a third heat-conducting medium which has one end abutting against the heat dissipation member <NUM> and the other end abutting against at least one of the first body <NUM> and the second body <NUM>; and the heat generated from at least one of the first body <NUM> and the second body <NUM> can be carried away more rapidly by the heat dissipation member <NUM> via the third heat-conducting medium.

Here, the heat dissipation member <NUM> is movable in the middle of the connection member <NUM>, and can absorb a dimensional cumulative error generated during production and assembly of the heat dissipation structure, such that the third heat-conducting medium has one end abutting against the heat dissipation member <NUM> and the other end abutting against at least one of the first body <NUM> and the second body <NUM>. Here, the third heat-conducting medium may be set to be thinner, and according to the calculation formula of thermal resistance, the thinner the heat-conducting medium is, the smaller the thermal resistance is, and the more heat can be transferred.

Here, the third heat-conducting medium may have a thickness equal to or slightly greater than a preset minimum thickness, that is, <NUM>. As an example, the third heat-conducting medium has a thickness less than or equal to <NUM>. Here, the third heat-conducting medium may be heat-conducting silicone grease.

For another example, when a preset distance is provided between the heat dissipation member <NUM> and at least one of the first body <NUM> and the second body <NUM>, the heat dissipation structure may further include a fourth heat-conducting medium which has one end abutting against the heat dissipation member <NUM> and the other end abutting against at least one of the first body <NUM> and the second body <NUM>. The fourth heat-conducting medium is elastic and has a thickness greater than the third heat-conducting medium. The heat generated from at least one of the first body <NUM> and the second body <NUM> can be carried away more rapidly by the heat dissipation member <NUM> via the fourth heat-conducting medium.

Here, the heat dissipation member <NUM> is fixedly disposed in the middle of the connection member <NUM>, and due to the elasticity, the fourth heat-conducting medium can absorb a dimensional cumulative error generated during production and assembly of the heat dissipation structure, such that the fourth heat-conducting medium has one end abutting against the heat dissipation member <NUM> and the other end abutting against at least one of the first body <NUM> and the second body <NUM>. Here, the fourth heat-conducting medium may be set to be thicker, so as to absorb the dimensional cumulative error generated during production and assembly of the heat dissipation structure.

Here, the fourth heat-conducting medium may have a thickness much greater than the preset minimum thickness. As an example, the fourth heat-conducting medium has a thickness in the range of <NUM> to <NUM>. Here, the fourth heat-conducting medium may be a heat-conducting pad or an ultra-flexible heat-conducting pad. As another example, the fourth heat-conducting medium has a thickness in the range of <NUM> to <NUM>. Here, the fourth heat-conducting medium may be an efficient heat-conducting pad.

In some examples not covered by the claims, the heat dissipation member <NUM> is fixedly disposed in the middle of the connection member <NUM>; and the preset distance is provided between the heat dissipation member <NUM> and at least one of the first body <NUM> and the second body <NUM>.

Here, the heat dissipation member <NUM> may have the preset distance from the first body <NUM>; or may have the preset distance from the second body <NUM>, or may have the preset distance from the first body <NUM> as well as from the second body <NUM>.

Here, the fixing manner of the heat dissipation member <NUM> is not limited.

In some implementations of the present disclosure, the heat dissipation structure includes an elastic member <NUM>. The elastic member <NUM> and the heat dissipation member <NUM> are both sleeved in the middle of the connection member <NUM>, and the elastic member <NUM> abuts against the heat dissipation member <NUM>. The heat dissipation member <NUM> is movable along the connection member <NUM> via deformation of the elastic member <NUM>, and each one of the first body <NUM> and the second body <NUM> has a distance, which is within the preset distance range, from the heat dissipation member <NUM>.

Here, via deformation of the elastic member <NUM>, the heat dissipation member <NUM> has the preset distance range from the first body <NUM> as well as from the second body <NUM>.

As an example, a first end of the elastic member <NUM> abuts against a first end of the heat dissipation member <NUM>; and a second end of the elastic member <NUM> may be fixedly disposed on the connection member <NUM>. Via deformation of the elastic member <NUM>, a second end of the heat dissipation member <NUM> has the preset distance range from the first body <NUM>, in which case the second end of the heat dissipation member <NUM> is located on the side of the first body <NUM>; or, via deformation of the elastic member <NUM>, the second end of the heat dissipation member <NUM> has the preset distance range from the second body <NUM>, in which case the second end of the heat dissipation member <NUM> is located on the side of the second body <NUM>.

As another example, the heat dissipation member <NUM> includes two parts. The first end of the elastic member <NUM> abuts against one part of the heat dissipation member <NUM>; and the second end of the elastic member <NUM> abuts against the other part of the heat dissipation member <NUM>. One part of the heat dissipation member <NUM> is located on the side of the first body <NUM>, and the other part of the heat dissipation member <NUM> is located on the side of the second body <NUM>. Via deformation of the elastic member <NUM>, one part of the heat dissipation member <NUM> has the preset distance range from the first body <NUM>; and via deformation of the elastic member <NUM>, the other part of the heat dissipation member <NUM> has the preset distance range from the second body <NUM>.

Here, those of ordinary skill in the art may set the shape and the structure of the elastic member <NUM> according to actual needs, as long as the elastic member <NUM> is elastic. For example, the elastic member <NUM> may be made of an elastic material. As an example, the elastic member <NUM> may be made of a rubber material. For another example, the elastic member <NUM> may have an elastic structure. As an example, the elastic member <NUM> may be a spring.

In some implementations of the present disclosure, the heat dissipation member <NUM> includes a first heat sink <NUM> and a second heat sink <NUM>. The first heat sink <NUM> is disposed in the middle of the connection member <NUM>, and located on the side of the first body <NUM> for dissipating heat from the first body <NUM>. The second heat sink <NUM> is disposed in the middle of the connection member <NUM>, and located on the side of the second body <NUM> for dissipating heat from the second body <NUM>.

In an exemplary embodiment of the present disclosure, the first heat sink <NUM> is disposed movable with respect to the connection member <NUM>. The second heat sink <NUM> is disposed movable with respect to the connection member <NUM>. Three arrangements of the first heat sink <NUM> and the second heat sink <NUM> are exemplarily listed below.

In a first arrangement of the first heat sink <NUM> and the second heat sink <NUM>, as shown in <FIG>, the heat dissipation structure further includes an elastic member <NUM>. The elastic member <NUM>, the first heat sink <NUM> and the second heat sink <NUM> are all sleeved in the middle of the connection member <NUM>, and the elastic member <NUM> abuts against each of the first heat sink <NUM> and the second heat sink <NUM>. The first heat sink <NUM> is fixed in position with respect to one end of the elastic member <NUM>, and the second heat sink <NUM> is fixed in position with respect to the other end of the elastic member <NUM>. The first heat sink <NUM> is movable along the connection member <NUM> via deformation of the elastic member <NUM>, and the first heat sink <NUM> has a distance, which is within the first preset distance range, from the first body <NUM>. The second heat sink <NUM> is movable along the connection member <NUM> via deformation of the elastic member <NUM>, and the second heat sink <NUM> has a distance, which is within the second preset distance range, from the second body <NUM>.

Here, the first heat sink <NUM> is movable with respect to the first body <NUM>, so that the first heat sink <NUM> can dissipate heat more flexibly from the first body <NUM>. The second heat sink <NUM> is movable with respect to the second body <NUM>, so that the second heat sink <NUM> can dissipate heat more flexibly from the second body <NUM>.

Here, the first preset distance range and the second preset distance range are similar to the preset distance ranges described above, and reference may be made thereto. The first preset distance range satisfies a condition that the first heat sink <NUM> can dissipate heat from the first body <NUM>. The second preset distance range satisfies a condition that the second heat sink <NUM> can dissipate heat from the second body <NUM>.

The elastic member <NUM> has been described above, and will not be detailed here.

Here, since the first heat sink <NUM> is fixed in position with respect to one end of the elastic member <NUM>, and the second heat sink <NUM> is fixed in position with respect to the other end of the elastic member <NUM>, it is realized that the elastic member <NUM> abuts against each of the first heat sink <NUM> and the second heat sink <NUM>, and positions of the first heat sink <NUM>, the elastic member <NUM> and the second heat sink <NUM> between the first body <NUM> and the second body <NUM> are defined.

Here, the manner for fixing the relative positions of the first heat sink <NUM> and one end of the elastic member <NUM> is not limited, and the manner for fixing the relative positions of the second heat sink <NUM> and the other end of the elastic member <NUM> is not limited. This may be achieved, for example, by providing another elastic structure.

Here, the elastic member <NUM> has a natural (undeformed) state or a pressed (deformed) state, and is pressed to be deformed when the first heat sink <NUM> or the second heat sink <NUM> is moved. It should be understood by those of ordinary skill in the art that when the first heat sink <NUM> is moved, the first heat sink <NUM> is fixed in position with respect to one end of the elastic member <NUM>, and when the second heat sink <NUM> is moved, the second heat sink <NUM> is fixed in position with respect to the other end of the elastic member <NUM>.

In some implementations of the present disclosure, to facilitate heat dissipation, the heat dissipation structure may further include a first heat-conducting medium <NUM> and a second heat-conducting medium <NUM>. The first heat-conducting medium <NUM> has one end abutting against the first heat sink <NUM> and the other end abutting against the first body <NUM>. The second heat-conducting medium <NUM> has one end abutting against the second heat sink <NUM> and the other end abutting against the second body <NUM>. Each of the first heat-conducting medium <NUM> and the second heat-conducting medium <NUM> has a thickness slightly greater than the preset minimum thickness.

Here, the first heat sink <NUM> is movable with respect to the first body <NUM>, and can absorb a dimensional cumulative error generated during production and assembly of the heat dissipation structure, such that the first heat-conducting medium has one end abutting against the first heat sink <NUM> and the other end abutting against the first body <NUM>. Here, the first heat-conducting medium may be set to be thinner, and according to the calculation formula of thermal resistance, the thinner the heat-conducting medium is, the smaller the thermal resistance is, the more heat can be transferred, and the more powerful the heat dissipation structure is.

Here, the second heat sink <NUM> is also movable with respect to the second body <NUM>, and can absorb a dimensional cumulative error generated during production and assembly of the heat dissipation structure, such that the second heat-conducting medium has one end abutting against the second heat sink <NUM> and the other end abutting against the second body <NUM>. Here, the second heat-conducting medium may also be set to be thinner, and according to the calculation formula of thermal resistance, the thinner the heat-conducting medium is, the smaller the thermal resistance is, the more heat can be transferred, and the more powerful the heat dissipation structure is.

Here, the first heat sink <NUM> and the second heat sink <NUM> are both movable, can absorb a dimensional cumulative error generated during production and assembly of the heat dissipation structure, and dissipate heat from the first body <NUM> and the second body <NUM>, respectively, with a more powerful heat dissipation capability, simpler structure and simpler installation operation.

The preset thickness has already been described above, and will not be detailed here.

Here, the first heat-conducting medium <NUM> and the second heat-conducting medium <NUM> are similar to the third heat-conducting medium described above, and reference may be made thereto.

Here, a limiting mechanism may be disposed in the middle of the connection member <NUM>. When the first heat-conducting medium <NUM> and the second heat-conducting medium <NUM> are not installed, it is realized by the limiting mechanism that the first heat sink <NUM> is fixed in position with respect to one end of the elastic member <NUM>, and the second heat sink <NUM> is fixed in position with respect to the other end of the elastic member <NUM>. When the first heat-conducting medium <NUM> and the second heat-conducting medium <NUM> are installed, it is realized by the first heat-conducting medium <NUM> that the first heat sink <NUM> is fixed in position with respect to one end of the elastic member <NUM>, and realized by the second heat-conducting medium <NUM> that the second heat sink <NUM> is fixed in position with respect to the other end of the elastic member <NUM>.

Here, referring to <FIG>, the first body <NUM> may be a mother board, which may include a PCB board and a mother board chip <NUM> (as an example of a first chip). The second body <NUM> may be a daughter board, which may include a PCB board and a daughter board chip <NUM> (as an example of a second chip). In this case, in order to facilitate cooling of the mother board chip <NUM> and the daughter board chip <NUM>, the first heat-conducting medium <NUM> may be disposed between the mother board chip <NUM> and the first heat sink <NUM>, and the second heat-conducting medium <NUM> may be disposed between the daughter board chip <NUM> and the second heat sink <NUM>.

In some implementations of the present disclosure, as shown in <FIG>, the connection member <NUM> may include a connection post <NUM>, a sleeve <NUM>, and a fixing post <NUM>. The first body <NUM> is provided with a first through hole matched with a shape of the connection post <NUM>, and the second body <NUM> is provided with a second through hole matched with a shape of the fixing post <NUM>. The connection post <NUM> passes through the first through hole such that a head end of the connection post <NUM> abuts against an outer side face of the first body <NUM>. The sleeve <NUM> is sleeved on an outer side of a tail end of the connection post <NUM> and abuts against an inner side face of the first body <NUM> and an inner side face of the second body <NUM>, respectively. The first heat sink <NUM>, the elastic member <NUM> and the second heat sink <NUM> are sleeved on an outer side of the sleeve <NUM>. The fixing post <NUM> has a head end abutting against the outer side face of the second body <NUM>, and a tail end passing through the second through hole and an opening of the sleeve <NUM> to be fixedly connected to the connection post <NUM>.

Here, as shown in <FIG> and <FIG>, the first body <NUM> and the second body <NUM> being relatively fixed in position is realized by the head end of the connection post <NUM> abutting against the outer side face of the first body <NUM>, the head end of the fixing post <NUM> abutting against the outer side face of the second body <NUM>, and the sleeve <NUM> abutting against an inner side face of the first body <NUM> and an inner side face of the second body <NUM> respectively.

Here, the manner for fixing the relative positions of the first heat sink <NUM> and one end of the elastic member <NUM> is not limited. The heat dissipation structure exemplarily shown in <FIG> may further include a first opening collar <NUM> (as an example positioning member) positioned on the outer side of the sleeve <NUM> and abutting against an end of the first heat sink <NUM> away from the elastic member <NUM>. When the first heat-conducting medium <NUM> is disposed between the first heat sink <NUM> and the first body <NUM>, the first heat-conducting medium <NUM> abuts against the first heat sink <NUM>.

Here, the manner for fixing the relative positions of the second heat sink <NUM> and the other end of the elastic member <NUM> is not limited. The heat dissipation structure exemplarily shown in <FIG> may further include a second opening collar <NUM> (as an example positioning member) positioned on the outer side of the sleeve <NUM> and abutting against the other end of the second heat sink <NUM> away from the elastic member <NUM>. When the second heat-conducting medium <NUM> is disposed between the second heat sink <NUM> and the second body <NUM>, the second heat-conducting medium <NUM> abuts against the second heat sink <NUM>.

Here, as shown in <FIG> and <FIG>, when the first body <NUM> and the second body <NUM> are fixedly connected by four sets of connection posts <NUM>, sleeves <NUM>, and fixing posts <NUM>, the four connection posts <NUM> may be disposed on one structure, as shown in <FIG>, and the heat dissipation structure may further include a substrate <NUM> on which the four connection posts <NUM> are disposed. Here, during assembly of the heat dissipation structure, the first heat sink <NUM>, the second heat sink <NUM> and the four elastic members <NUM> may be first mounted on the four sleeves <NUM> to form an integral heat dissipation structure, as shown in <FIG>. Then, the first body <NUM>, the integral heat dissipation structure and the second body <NUM> are sequentially sleeved on the four connection posts <NUM> of the substrate <NUM>. Finally, the four connection posts <NUM> are respectively and fixedly connected via the four fixing posts <NUM>. Here, the four connection posts <NUM> of the substrate <NUM> are assembled at the same time, which makes the assembly simple and the installation efficient.

For another example not covered by the claims, the first heat sink <NUM> is fixedly disposed in the middle of the connection member <NUM>, and the first heat sink <NUM> has the first preset distance from the first body <NUM>; and the second heat sink <NUM> is fixedly disposed in the middle <NUM> of the connection member, and the second heat sink <NUM> has the second preset distance from the second body <NUM>.

Here, the first preset distance and the second preset distance are similar to the preset distance described above, and reference may be made thereto. The first preset distance satisfies a condition that the first heat sink <NUM> can dissipate heat from the first body <NUM>. The second preset distance satisfies a condition that the second heat sink <NUM> can dissipate heat from the second body <NUM>.

Here, to facilitate heat dissipation, a fifth heat-conducting medium may be disposed between the first heat sink <NUM> and the first body <NUM>, and a sixth heat-conducting medium may be disposed between the second heat sink <NUM> and the second body <NUM>.

Here, the fifth and sixth heat-conducting media are similar to the fourth heat-conducting medium described above, and reference may be made thereto.

For another example not covered by the claims, in a third arrangement of the first heat sink <NUM> and the second heat sink <NUM>, the heat dissipation structure further includes an elastic member <NUM>. The first heat sink <NUM> is fixedly disposed in the middle of the connection member <NUM>, and the first heat sink <NUM> has the first preset distance from the first body <NUM>. The second heat sink <NUM> and the elastic member <NUM> are both sleeved in the middle of the connection member <NUM>, and the elastic member <NUM> has a first end abuts against the second heat sink <NUM> and a second end fixedly disposed. The second heat sink <NUM> is movable along the connection member <NUM> via deformation of the elastic member <NUM>, and the second heat sink <NUM> has a distance, which is within the second preset distance range, from the second body <NUM>.

The elastic member <NUM>, the first preset distance range and the second preset distance range have been described above, and will not be detailed here.

Here, to facilitate heat dissipation, a fifth heat-conducting medium may be disposed between the first heat sink <NUM> and the first body <NUM>, and a second heat-conducting medium <NUM> may be disposed between the second heat sink <NUM> and the second body <NUM>.

The fifth heat-conducting medium and the second heat-conducting medium <NUM> have already been described above, and will not be detailed here.

Here, it should be understood by those of ordinary skill in the art that the second heat sink <NUM> may be fixedly disposed, and the first heat sink <NUM> may be disposed movable, which is specifically implemented in a manner similar to the aforementioned third arrangement of the first heat sink <NUM> and the second heat sink <NUM>, and reference may be made thereto.

In some implementations of the present disclosure, as shown in <FIG>, the heat dissipation structure may further include: a socket <NUM> disposed at an inner side of the first body <NUM>, and a plug <NUM> disposed at an inner side of the second body <NUM>. The plug <NUM> is inserted into the socket <NUM> such that the first body <NUM> and the second body <NUM> are electrically connected, so as to perform information interaction between the first body <NUM> and the second body <NUM>.

In an exemplary embodiment of the present disclosure, the heat dissipation member <NUM> is disposed in the middle of the connection member <NUM>, and while the connection member <NUM> is fixedly connected to the first body <NUM> and the second body <NUM>, heat from at least one of the first body <NUM> and the second body <NUM> may be dissipated via the heat dissipation member <NUM>, which is simple in structure and easy to install and operate, thereby improving installation efficiency, reducing the number of mounting holes formed in the first body <NUM> and the second body <NUM>, and increasing space utilization of the first body <NUM> and the second body <NUM>.

The present disclosure also provides an electronic device including the heat dissipation structure described in the above exemplary embodiments.
