HEAT EXCHANGE DEVICE

摘要

A heat exchange device in which heat exchangers are sequentially connected through header tanks. Each heat exchanger has, as a core section, tubes in which fluid flows and wavy fins that are placed between the tubes. The header tanks each have a core plate section, at which tubes of each heat exchanger are joined at portions near their ends, and the header tanks connect the core plate sections together so that the core plate sections are in intimate contact with and fixed to each other. The end sides of the tubes are open to a closed space in each header tank.
