Title
(EN) HEAT EXCHANGER HEADER, HEAT EXCHANGER HAVING THE HEAT EXCHANGER HEADER, REFRIGERATION CYCLE APPARATUS AND AIR-CONDITIONING APPARATUS
Abstract
(EN)

A heat exchanger header for a heat exchanger in which refrigerant is flowed in parallel through a plurality of flat tubes disposed in parallel includes a header main body in which a plurality of through-holes are arranged side by side in a longitudinal direction, and a lid body that is joined to the header main body. At least one chamber communicating with the plurality of through-holes and serving as a refrigerant flow passage is formed between the header main body and the lid body. Each of the plurality of through-holes is an inlet side through-hole or an outlet side through-hole to which a refrigerant inlet side end or a refrigerant outlet side end of the plurality of flat tubes is connected. In a part of the lid body that faces the inlet side through-holes, a plurality of grooves are formed in a lateral direction perpendicular to the longitudinal direction.
