Artificial resin heat exchanger for vehicle air conditioner has heat exchange plate parts and holding part formed integrally by extrusion of resin material

摘要

he heat exchanger has a core part (11) with heat exchange plates (12) forming internal fluid channels (19) and surrounded by holding parts (41, 42). The plates are arranged in layers with cavities between them so that external fluid channels (36) are also formed. The heat exchange plate parts and the holding part are formed integrally by extrusion of the resin material.
