Problems solved by technology

Therefore, when the metal member and the resin member are kept pressed against each other while being joined, there is a problem that resin (or flash) protruding from the joint portion increases
Meanwhile, if the metal member and the resin member are not pressed against each other in order to suppress the occurrence of flash in the joint, there is a problem that air bubbles generated by melting of the resin remain in the resin member in the joint, resulting in a decrease in strength.

Abstract

A polar functional group is added onto a surface of a metallic member (1). A resin member (2) contains an adhesive functional group. The adhesive functional group and the polar functional group attract each other. A method for joining the metallic member (1) and the resin member (2) to each other includes a heating a junction between the metallic member (1) and the resin member (2) while pressing the metallic member (1) and the resin member (2) against each other with first load, maintaining temperature of the junction higher than melting temperature of a resin that structures the resin member (2) while pressing the metallic member (1) and the resin member (2) with each other with second load smaller than the first load, and cooling the junction to temperature lower than the melting temperature while pressing the metallic member and the resin member against each other with third load larger than the second load.

Description

technical field [0001] The present invention relates to a method of joining a metal member and a resin member to each other, a method of manufacturing a cooler, and a cooler. Background technique [0002] In recent years, various types of industrial products have been developed in which a metal member having excellent thermal conductivity, electrical conductivity, ductility, etc. and a lightweight and inexpensive resin member are joined to each other. Needless to say, in such industrial products, the reliability of a joint made of different materials between a metal member and a resin member becomes a problem. [0003] Japanese Patent Application Publication No. 2010-173274 (JP2010-173274A) discloses a joining method in which, in order to rigidly adhere a metal member and a resin member to each other, a polar functional group is applied to the surface of the metal member, and a The adhesiveness modifier of the adhesive functional group which interacts with the above-mention...
