Abstract: A phase-change heat exchanger and a heat exchange core thereof are provided according to the present application, which include an evaporator and a condenser which is in communication with the evaporator and is located above the evaporator, and at least one of the evaporator and the condenser is inclined in the housing. In the actual use, since at least one of the evaporator and the condenser is inclined in the housing, a space in a thickness direction of an inner cavity of a housing of the phase-change heat exchanger can be fully utilized, a span in a connection direction between the evaporator and the condenser can be reduced, and thus an overall volume of the phase-change heat exchanger can be reduced.

Abstract: A heat exchanger includes a heat exchange core arranged inside the housing, and a side of the housing is provided with an air vent. The heat exchanger is provided with a communication channel in communication with the air vent. The communication channel is located inside the housing, and is located at a side in the housing opposite to the air vent. In the heat exchanger, the air vent is in communication with the communication channel inside the housing, and the communication channel is located at the side in the housing opposite to the air vent, such that the internal space of the housing is fully utilized. Compared to the prior art, the overall size of the heat exchanger is reduced, and the cost for the heat exchanger is reduced.
