HEAT EXCHANGER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2022/149413
Kind Code:
A1
Abstract:
A heat exchanger (1), wherein a refrigerant distributor (30A) has a plurality of insertion holes (31) and a contact portion (32) that is provided so as to protrude from the outer periphery of at least one of the insertion holes (31). One end of each of a plurality of flattened multi-hole tubes (10) is inserted into the insertion holes (31) of the refrigerant distributor (30A). A group of fins (20) has an end face (20b) facing the refrigerant distributor (30A) while in contact with the contact portion (32). The end face (20b) is positioned away from the one end by a length equivalent to the sum of the length (IL) of insertion of the one end in the flattened multi-hole tube (10) and the protrusion height (H1) of the contact portion (32).
