Title:

HEAT EXCHANGER AND REFRIGERATION CYCLE APPARATUS

Document Type and Number:

WIPO Patent Application WO/2021/149223

Kind Code:

A1

Abstract:

A heat exchanger comprising: a plurality of heat transfer tubes positioned so as to leave gaps between each other in a first direction, the plurality of heat transfer tubes channeling a refrigerant in a second direction that intersects the first direction; and a refrigerant distributor extending in the first direction, the refrigerant distributor being connected to one end of each of the plurality of heat transfer tubes and distributing the refrigerant to the plurality of heat transfer tubes. The refrigerant distributor has formed in the interior thereof a first channel and a second channel in which the refrigerant flows. The first channel is formed so as to extend in the first direction. The first channel connects to an inflow tube, which communicates with the plurality of heat transfer tubes and causes the refrigerant to flow into the interior of the refrigerant distributor. The second channel is formed so as to extend in the first direction and so that both end sections connect to the first channel, and is formed so as to be located in a third direction relative to the first channel, where the third direction is defined as a direction that intersects a plane parallel to the first direction and the second direction.
