Title:
HEAT EXCHANGER AND AIR-CONDITIONER PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2020/161761
Kind Code:
A1
Abstract:
This heat exchanger is provided with: a plurality of heat transfer tubes; and a cylindrical refrigerant distributor having insertion holes which are formed in a first direction so as to have gaps therebetween and through which the ends of the heat transfer tubes are inserted from a second direction. The refrigerant distributor is provided with: a first partition plate for partitioning the inside into a first space located on the side where the ends of the heat transfer units are inserted and a second space that is located on the side where the ends of the heat transfer units are not inserted and that has a volume larger than that of the first space; and an inflow tube that is provided to one lateral surface so as to cause a gas-liquid two-phase refrigerant to flow into the second space. In the first space, the heat transfer tubes are inserted in the insertion holes so have ends thereof being located apart from the first partition plate. The first partition plate is provided with orifices which are for connecting the first and second spaces with each other and which are formed so as to correspond to gaps between adjacent heat transfer tubes.
