Title:
熱交換器、空気調和装置、及び熱交換器の製造方法
Document Type and Number:
Japanese Patent JP7323820
Kind Code:
B2
Abstract:
A heat exchanger (30) comprises an aluminum heat transfer pipe (35), an aluminum refrigerant pipe (36) connected to the heat transfer pipe (35), an aluminum flow branching part (37) connected to a plurality of refrigerant pipes (36), and a pressure-reducing valve (50) connected to the flow branching part (37). The pressure-reducing valve (50) has a valve body (51) and a joint pipe (52). The flow branching part (37) has a first connection section (37b) that is connected to the joint pipe (52) by high-frequency brazing.
