Title:
熱交換器及び空気調和装置
Document Type and Number:
Japanese Patent JP6562096
Kind Code:
B2
Abstract:
The corrosion resistance of a heat exchanger made of aluminum or an aluminum alloy is inexpensively improved. A coupling header (200) includes a first member (210) having a first outer surface (217) and a first inner surface (218) where a heating medium flows. The first member (210) includes a first core (311) made of an aluminum alloy and a first sacrificial anode layer (312) disposed on the first outer surface (217). A second member (220) includes no sacrificial anode layer, and is made of an aluminum alloy. The second member (220) has a second outer surface (229) and a second inner surface (228) where the heating medium flows. A third member (230) has an exposed surface (237). The third member (230) includes a second core (331) made of an aluminum alloy, and a second sacrificial anode layer (332) disposed on the exposed surface (237). The third member (230) covers a partial region of the second outer surface (229) of the second member (220) with a joining surface (238) joined to the partial region.
