HEAT EXCHANGER

摘要

The provision of a heat exchanger that can achieve both improving the pressure-resistant strength of headers and suppressing pressure loss of refrigerant. A heat exchanger is equipped with a pair of headers and plural flat tubes (11a to 11f). Each of the headers has a first member (131) and a flat tube holding member (132) to which end portions of the flat tubes (11a to 11f) are adhered and which holds the flat tubes (11a to 11f). The first member (131) has formed therein a refrigerant main flow path (131a), which extends in an up-and-down direction and through which refrigerant flows, and refrigerant connection flow paths (231 a to 231f), which extend from the refrigerant main flow path (131a) to an end surface in the direction in which the flat tubes (11a to 11f) are positioned in order to circulate the refrigerant between the refrigerant main flow path (131a) and plural refrigerant flow paths formed in the flat tubes (11a to 11f). Intermediate flow paths (133a to 133f) that interconnect the refrigerant connection flow paths (231a to 231f) and the plural refrigerant flow paths in the flat tubes (11a to 11f) are formed in the headers and/or the flat tubes (11a to 11f).
