Problems solved by technology

[0007] However, in the evaporator with a cool storage function described in the above-mentioned publication, one side of the refrigerant flow pipe and the outer surface of the side wall of the cold storage material container are brazed in a surface-contact manner. Therefore, in this case, the refrigerant flow pipe The brazing between the single side and the outer surface of the side wall of the cold storage material container is reduced, and there is a possibility of an unbrazed part between the two

Abstract

In a method of manufacturing an evaporator with a cool storage function, a plurality of flat refrigerant flow tubes and a plurality of container forming assemblies are disposed such that a width direction of each of the plurality of flat refrigerant flow tubes and a width direction of each of the plurality of container forming assemblies coincide with a vertical direction. Peripheral edge portions of container forming plates are brazed together to prepare each of the cool storage material containers. The flat refrigerant flow tubes and the cool storage material containers are brazed together.

Description

technical field [0001] The present invention relates to a method of manufacturing an evaporator with a cool storage function used in an automotive air conditioner for temporarily stopping an engine as a driving source of a compressor when the vehicle is stopped. Background technique [0002] In this specification and claims, the figure 1 The up and down is called up and down. [0003] In recent years, for the purpose of protecting the environment and improving the fuel efficiency of automobiles, automobiles that automatically stop their engines when they stop at traffic lights or the like have been proposed. [0004] However, in a general car air conditioner, when the engine is stopped, the compressor driven by the engine stops, so that refrigerant is no longer supplied to the evaporator, causing a problem that the cooling capacity drops sharply. [0005] Therefore, in order to solve such a problem, it is conceivable to provide a cool storage function to the evaporator so ...
