no. 1 approach

[0030] A first embodiment of the present invention will be described in detail with reference to the drawings. Such as figure 1 As shown, in this embodiment, the case where the composite member 1 is formed by joining the plate-shaped resin member 2 and the plate-shaped metal member 3 as an example is demonstrated.

[0031] The method of joining a resin member and a metal member (hereinafter simply referred to as "joining method") of the present embodiment includes: a superposition step in which the resin member 2 and the metal member 3 are superimposed; and a friction stir step in which the The metal member 3 undergoes friction stirring.

[0032] First, in the coincidence process, such as figure 1 As shown, the metal member 3 is placed on the resin member 2 so that a part of the upper surface of the resin member 2 is in contact with a part of the lower surface of the metal member 3 . In this embodiment, the resin member 2 is a plate-shaped member made of PET (polyethylene t...

no. 2 approach

[0044] Next, a second embodiment of the present invention will be described. In this embodiment, if image 3 As shown, a case where a liquid cooling jacket P having a resin jacket main body 10 and a metal (in this embodiment, aluminum alloy in this embodiment) package 30 is manufactured will be described as an example. The liquid cooling jacket P is used, for example, to cool heat-generating bodies such as a CPU (central processing unit; central processing unit).

[0045] Such as image 3 As shown, the liquid-cooled jacket P consists of a jacket body 10 having a recess 11 for the flow of water (not shown) as a heat transfer fluid and a part of the opening, and a package body 30 fixed to the opening 12 of the package recess 11 of the jacket body 10. In this configuration, the heat transfer fluid transfers heat generated by a CPU (not shown) as a heat generator to the outside.

[0046] The liquid cooling jacket P is installed with a CPU (not shown) through the heat sink (not ...

no. 3 approach

[0064] Next, a third embodiment of the present invention will be described. In the first and second embodiments, the friction stir process is performed using the rotary tool G for friction stirring to join the resin member 2 and the metal member 3 , while in the third embodiment, the friction stirring process is performed using the rotary tool F. The process is different from the first embodiment and the second embodiment.

[0065] The bonding method of the present embodiment includes: a superposing step in which the resin member 2 and the metal member 3 are superimposed; and a friction step in which the superimposed members are frictionally joined. About the overlapping process, since it is the same as that of 1st Embodiment, the description is abbreviate|omitted.

[0066] In the rubbing process, such as Figure 8 As shown, the resin member 2 and the metal member 3 (aluminum alloy member 3 ) are frictionally joined using a rotary tool F (hereinafter also referred to as a fr...

Abstract

Provided are a method for joining a resin member with a metal member which allows them to be joined easily while achieving a sufficient level of joint strength, and a liquid-cooled jacket manufacturing method. The joining method is characterized in that after a resin member (2) and a metal member (3) are overlapped, a rotating friction stir tool (G) is pressed from the metal member (3) side and the two members are joined by the heat of friction. According to said joining method, after the resin is melted by the heat of friction, the resin member (2) fuses to the metal member (3) as the temperature drops, so the members can be joined easily and firmly.

Description

technical field [0001] The present invention relates to a method of joining a resin member and a metal member and a method of manufacturing a liquid cooling jacket having the resin member and the metal member. Background technique [0002] Technologies for bonding or mechanically bonding resin components and metal components are being sought in a wide range of fields, including the automotive industry and the industrial equipment industry. The use of an adhesive material is mentioned as a relatively simple method of joining a resin member and a metal member. On the other hand, there is a problem that sufficient strength cannot be obtained with an adhesive material. Therefore, in the technique disclosed in Patent Document 1, after inserting a metal member made of aluminum alloy into a mold in advance, a resin plastic material is injected into the mold to join the two members. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2007-50630 Contents of the invention ...
