BRAZING PLATE HEAT EXCHANGER

摘要

PROBLEM TO BE SOLVED: To provide a brazing plate heat exchanger that prevents corrosion of a base part by using a resin while suppressing cost increase for mass production of the heat exchanger.SOLUTION: A tap base is brazed without brazing a base to a heat exchanger body. A base made of a material high in chlorine corrosion resistance is fixed to the tap base by a bolt or the like. A distal end of the base is made to reach an edge of the heat exchanger body to prevent a brazing part between the heat exchanger body and the tap base from contacting liquid. Corrosion is prevented by corrosion-resistant packing sandwiched between the base and the heat exchanger body.
