In a related technology, when the heat exchanger which is in an A shape is produced, a most part of the heat exchanger is directly bent from the middle. After being bent, the plurality of heat exchange tubes are disposed in parallel and horizontally disposed on the fin to fix. However, difficulty of bending the plurality of heat exchange tubes is relatively high, improper operation may cause scratches and damage to a product, leading to leakage problems, and bending may affect a heat exchange performance of the heat exchanger. In addition, the heat exchanger which is in the A shape is used as a heat pump heat exchanger, condensed water is prone to accumulate between the fin and the plurality of heat exchange tubes and hard to flow away from the fin. The condensed water accumulated between the fin and the plurality of heat exchange tubes is prone to frost, such that a problem of frost formation occurs in the heat exchanger, resulting in affecting the heat exchanger to use.

In the present disclosure, the two heat exchange assemblies are inclined and connected to each other via the connecting assembly, such that the heat exchanger may not be required to be bent in the A shape, resulting in reducing difficulty of production and processing. The fin unit is disposed in parallel, and the heat exchange tube units is disposed horizontally, such that after the condensed water between the fin unit and the heat exchange tube unit accumulating to a certain volume, the condensed water may flow from the fin unit to the heat exchange tube unit, and flow away along a smooth pipe wall of the heat exchange tube unit, so as to prevent the heat exchanger from frost formation due to an accumulation of the condensed water.

In the heat exchanger, the plurality of heat exchange tube unit 11 may be in a horizontal state by fixing the plurality of heat exchange tube units 11 on two of the plurality of fin units 12 disposed in parallel, such that after condensed water between the plurality of fin units 12 and the plurality of heat exchange tube units 11 flowing onto the plurality of heat exchange tube units 11, the condensed water may flow away along a smooth pipe sidewall of the plurality of heat exchange tube units 11, resulting in improving a discharging capacity of the heat exchanger, and preventing the heat exchanger from frosting due to the accumulation of the condensed water. Furthermore, the two heat exchange assemblies 1 are inclined relative to and connected to each other via the connecting assembly 2, such that after the heat exchanger disposing on a bearing surface (such as a surface of a ground, tabletop, or other supporting body), the plurality of fin units 12 and the plurality of heat exchange tube units 11 may be in an inclined state relative to the bearing surface, facilitating the condensed water flowing away from the plurality of heat exchange tube units 11.
