HEAT EXCHANGER

摘要

A heat exchanger 100 disclosed is a heat exchanger that exchanges heat between a first fluid and a second fluid. The heat exchanger 100 includes: a resin structure 10 forming a first flow path through which the first fluid flows; and a copper pipe 20 forming a second flow path through which the second fluid flows, the copper pipe 20 having at least a portion disposed in the first flow path. A resin component of a resin composition constituting the resin structure 10 contains, as a main component, a polymer alloy of a polyphenylene ether resin and a polystyrene resin. A mass ratio of the polyphenylene ether resin to the polystyrene resin in the polymer alloy is in the range of 40/60 to 65/35.
