Embodiment 1

[0047] refer to figure 1 , figure 1 It is a schematic diagram of the friction stir welding and glued compound connection joint of the radiator of the present invention; this figure is a cross section of part of the water channel of the water-cooled radiator. The method of this embodiment is completed by the following steps: Step 1: Process the water-cooled radiator into the form of a base plate and a cover plate, process the base plate 1 into a process step 7, and clean the weld position; Step 2: Coat the metal with a synthetic adhesive On the process step 7 of the whole welding seam, cover the cover plate and apply a certain pressure to make the glue solidify, and the cover plate 2 and the base plate 1 are firmly adhered; Step 3: Perform friction stirring on the docking surface of the base plate 1 and the cover plate 2 Welding, to complete the sealing welding of the waterway welds, to form a composite weld of friction stir welding and adhesive bonding.

Embodiment 2

[0049] refer to figure 2 and image 3 , figure 2 It is a schematic diagram of friction stir welding and glue joint composite connection of U-shaped circulating water radiator, image 3 yes figure 2 Sectional view of plane A-A in the center; figure 2 In the process, the circulating water enters the U-shaped circulating water channel through the water inlet 6; because of the narrow width of the abutment, it is impossible to process a process step of sufficient width for friction stir welding. Because the joint strength requirement of the internal abutment and the cover plate is not high, it has no essential influence on the sealing of the product, so the weld between the abutment and the cover plate can be used as an internal weld seam, and only glued for connection, as shown in the figure As shown in 3, the bonding part 5 is formed, which can guide the flow direction of the liquid in the water channel and prevent the flow between the steps of the water channel and the c...

Embodiment 3

[0051] refer to Figure 4 and Figure 5 , Figure 4 It is a schematic diagram of friction stir welding and adhesive bonding composite connection of serpentine circulating water radiator, Figure 5 yes Figure 4 Sectional view of plane A-A in the center; Figure 4 In the process, the circulating water enters the serpentine circulating water channel through the water inlet 6; the water-cooled radiator is divided into a base plate and a cover plate for processing and molding, but because the distance between adjacent water channels is narrow, it cannot meet the size requirements of the process step 7, so the corresponding The abutment and the cover between the adjacent water channels are designed as an overlapping structure, and the abutment and the cover are connected by adhesive technology, such as Figure 5 As shown, a plurality of adhesive joints 5 are formed to block circulating water from flowing between the abutment 1 and the cover plate 2 and prevent the cover plate f...

Abstract

The invention provides a composite connection method for radiator type products and relates to the technical field of welding methods. The technical problems that a radiator inner cavity is poor in sealing performance, and a friction stir welding tool is high in requirement are solved. The method includes the following steps that a radiator comprises a base plate and a cover plate, the base plateis provided with a process step, and a weld joint position is cleaned completely; the process step of a whole weld joint is coated with a synthesis gluing agent for metal, the cover plate is arrangedfor covering, pressure is applied, glue is made solidified, and adhesion between the cover plate and the base plate is firm; friction stir welding is performed on the butt joint face of the base plateand the cover plate, sealing welding on the weld joint is completed, and a friction stir welding and gluing composition connection joint is formed. By means of the composite connection method for theradiator type products, the sealing performance and the pressure bearing capacity of radiator water channels can be improved, the cross sectional area of the water channels and the distribution density of the water channels are improved, tool requirements are lowered, the radiating performance is improved, the structure is simple, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of welding methods, in particular to a composite connection method for radiator products. Background technique [0002] Due to the advantages of aluminum alloy materials such as excellent thermal conductivity, high specific strength, and low price, aluminum water-cooled radiators are more and more widely used in high-density heat dissipation occasions. [0003] Friction stir welding uses frictional heat and plastic deformation heat as the welding heat source. It is inserted into the joint of the workpiece by a cylinder or other shape (such as a threaded cylinder) stirring needle, through the high-speed rotation of the welding head, so that It rubs against the material of the welding workpiece, so that the temperature of the material at the joint is raised and softened, and at the same time, the material is stirred and rubbed to complete the welding. [0004] Friction stir welding has the advantages of good ...
