Title:
HEAT EXCHANGER AND AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/015272
Kind Code:
A1
Abstract:
This heat exchanger comprises: a heat dissipation unit (20) that is provided with a heat exchange core (230) that dissipates heat from a high-pressure refrigerant into a first air flow by heat exchange between the first air flow and the high-pressure refrigerant; and an evaporator (22) that is disposed above the heat dissipation unit and evaporates a low-pressure refrigerant by causing the low-pressure refrigerant to absorb heat from a second air flow by heat exchange between the second air flow and the low-pressure refrigerant. In this heat exchanger, the condensed water generated from the evaporator by the heat exchange in the evaporator is guided to the windward side of the first air flow in the heat exchange core of the heat dissipation unit, and the guided condensed water is applied to the heat exchange core to dissipate heat from the high-pressure refrigerant into the condensed water and vaporize the condensed water.
