Title:
METHOD FOR MANUFACTURING HEAT EXCHANGER AND HEAT EXCHANGER OBTAINED BY SAME
Document Type and Number:
WIPO Patent Application WO/2013/094249
Kind Code:
A1
Abstract:
Provided is a method of joining a large diameter water pipe to a small diameter refrigerant pipe to manufacture a heat exchanger, such that dropping of molten solder is advantageously prevented and effective joining of the water pipe to the refrigerant pipes is achieved while reduction in the strength of base materials is effectively suppressed. In the manufacture of a heat exchanger formed by joining a small diameter refrigerant pipe to the outer peripheral surface of a large diameter water pipe, strip-like solder plate material is used for the joining material, and after the solder plate material is mounted on the outer peripheral surface of a water pipe so as to be sandwiched with the refrigerant pipe, the solder plate material is melted by heating to a temperature that does not exceed 350°C, and the water pipe and refrigerant pipe are joined.
