Title:
HEAT EXCHANGER, HEAT EXCHANGE MODULE, AND REFRIGERATION CYCLE
Document Type and Number:
WIPO Patent Application WO/2019/186674
Kind Code:
A1
Abstract:
The present invention provides: a heat exchanger in which a refrigerant can be more uniformly distributed to a plurality of heat exchange pipes; a heat exchange module; and an air conditioner. A heat exchanger (31) is provided with: a pair of header pipes (32), (33) arranged substantially in parallel; a plurality of flat pipes (35) which are arranged in the extension direction of the pair of header pipes (32), (33) and installed between the pair of header pipes (32), (33), and which circulate a refrigerant between the upstream-side header pipe (32) and the downstream-side header pipe (33); and an upstream-side connector (37) that delivers the refrigerant into the upstream-side header pipe (32). The upstream-side connector (37) has: a distal end opening (45) provided at the distal end thereof; and at least one lateral opening (46) provided on a side surface of the upstream-side connector (37) and facing an inner surface (32c) of the upstream-side header pipe (32). The angle θ formed between an opening direction (Z2) of the lateral opening (46) of the upstream-side connector (37) and a line segment L perpendicular to the header pipe is smaller than 45 degrees. The opening area of the lateral opening (46) is less than the opening area of the distal end opening (45).
