Abstract

The invention relates to a refrigerant distributor and a heat exchanger equipped with the refrigerant distributor. The refrigerant distributor has a header (10a) and a disperser (40). One end of a plurality of flat tubes (20) of a heat exchanger (1) configured in parallel to a plurality of flat tubes (20) is connected, and the inside is divided between a plurality of heat transfer tubes (20) by more than one partition plate (11). ) is arranged vertically in the vertical direction; the disperser (40) distributes the refrigerant into each chamber in the header (10a) separated by the partition plate (11).

Description

technical field [0001] The present invention relates to, for example, a refrigerant distributor that is mounted on a heat exchanger of a refrigeration cycle device used in an air conditioner and the like to distribute refrigerant, and a heat exchanger, a refrigeration cycle device, and a heat exchanger equipped with the refrigerant distributor. air conditioner. Background technique [0002] Conventionally, there is a heat exchanger configured as follows: a pair of headers extending in the vertical direction are arranged apart from each other in the left-right direction, a plurality of flat tubes are arranged in parallel between the pair of headers, and both ends of the plurality of heat exchange tubes are connected to each other. communicated with a pair of manifolds. In such a heat exchanger, when used as an evaporator, since the refrigerant flows in as a gas-liquid two-phase flow, in the header on the inlet side, the liquid accumulates in the direction of gravity, and on ...
