Title:
HEAT EXCHANGER AND AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/013517
Kind Code:
A1
Abstract:
This heat exchanger comprises: a heat dissipation unit (20) that dissipates heat from a first refrigerant into a first airflow; and an evaporator (22) that is disposed above the heat dissipation unit in the vertical direction and causes a second refrigerant to absorb heat from a second airflow and evaporate. Condensate produced in the evaporator flows to the heat dissipation unit to cool the first refrigerant. The half region on the inlet side of a first refrigerant flow path in the heat dissipation unit is designated as a first region (250), the half region on the outlet side is designated as a second region (251), the half region on the first region side of a second airflow path in the evaporator is designated as a third region (240), the half region (241) on the second region side is designated as a fourth region, and the airflow rate of the second airflow flowing in the third region is greater than the airflow rate of the second airflow flowing in the fourth region.
