HEAT EXCHANGER AND AIR CONDITIONER

摘要

A heat exchanger includes a plurality of flat tubes arranged one above the other, a plurality of fins connected to the flat tubes, a first header collecting pipe in which one end of each of the plurality of flat tubes is inserted, and a second header collecting pipe in which the other end of each of the plurality of flat tubes is inserted. The heat exchanger exchanges heat between a fluid flowing through the flat tubes and air outside the flat tubes. Each of the first and second header collecting pipes extends in a vertical direction. At least one of the first and second header collecting pipes comprises a communication space that communicates with an upstream side of the plurality of flat tubes when the heat exchanger functions as an evaporator. The communication space comprises a partition plate.

1. A heat exchanger, comprising:
a plurality of flat tubes arranged one above the other; a plurality of fins connected to the flat tubes; a first header collecting pipe in which one end of each of the plurality of flat tubes is inserted; and a second header collecting pipe in which the other end of each of the plurality of flat tubes is inserted, wherein the heat exchanger exchanges heat between a fluid flowing through the flat tubes and air outside the flat tubes, each of the first and second header collecting pipes extends in a vertical direction, at least one of the first and second header collecting pipes comprises an upstream communication space that communicates with an upstream side of the plurality of flat tubes when the heat exchanger functions as an evaporator, the heat exchanger further comprises a partition plate disposed in the upstream communication space, the partition plate extends in the vertical direction and divides the upstream communication space into a first space in communication with the plurality of flat tubes and a second space in communication with an inlet portion that introduces a refrigerant into the upstream communication space when the heat exchanger functions as an evaporator, and a communication path, formed at a lower portion of the upstream communication space, through which the first space and the second space communicate.
