Title:
HEAT EXCHANGER, ELECTRIC CONTROL BOX AND AIR-CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/042564
Kind Code:
A1
Abstract:
Disclosed are a heat exchanger, an electric control box and an air-conditioning system. The heat exchanger comprises: a heat exchange main body comprising a first pipe body and a second pipe body nested with each other, with the first pipe body being internally provided with a plurality of first micro-channels, and the second pipe body being internally provided with a plurality of second micro-channels; and a header pipe assembly comprising a first header pipe and a second header pipe, wherein the first header pipe is provided with a first header channel which is used for providing a first refrigerant flow for the plurality of first micro-channels and/or collecting the first refrigerant flow flowing through the plurality of first micro-channels, and the second header pipe is provided with a second header channel which is used for providing a second refrigerant flow for the plurality of second micro-channels and/or collecting the second refrigerant flow flowing through the plurality of second micro-channels. According to the solution, the size of the heat exchanger is reduced, the heat exchange area between the first pipe body and the second pipe body can be increased, and the heat exchange efficiency of the heat exchanger is improved.
