Problems solved by technology

[0002] At present, the B-type tubes commonly used in the radiator water tank cooling pipes of automobiles are mostly made of aluminum materials. The thermal conductivity of aluminum materials is not good. After using aluminum materials to prepare radiators, it is easy to have poor heat dissipation effect.
When using aluminum to prepare heat sinks, aluminum with a brazing layer is often used for welding. After the aluminum is bent into the desired shape, voltage is applied to both sides of the welding point to dissolve the brazing layer and combine with the aluminum. At present, there is no copper material on the market to prepare B-type tubes, and because the heat pipe has a high requirement for thickness, the thinner the B-type tube is, the better the heat dissipation effect is, but the thinner the B-type tube is, the higher the welding method requirements are. , the surface of copper does not have a brazing layer, and it cannot be brazed like aluminum. Therefore, looking for a B-type heat pipe welding method that can solve the above problems

Embodiment 1

[0030] An efficient welding method for B-type heat pipes, comprising the following steps:

[0031] (1) Folding ribs: Take the copper sheet and place it on the tube body forming device. The copper material is sent to the rib forming roller and passed through the pressing to form the reinforcing rib. The tube forming device is equipped with several sets of rib forming rollers. The reinforcing rib forming roller is provided with a U-shaped rolling opening that fits up and down, and the rolling opening gradually shrinks so that the copper material finally forms a closed U-shaped reinforcing rib, and the reinforcing rib is located at a quarter of the width of the entire copper material. ;

[0032] (2) add tin-lead: the copper material that has stiffener in step (1) is sent to tin-lead outlet, sprays a tin-lead line on copper material; Described tin-lead is tin-lead solder, and wherein tin content is 30-50%, the position of the tin-lead line is located at three quarters of the widt...

Abstract

The invention discloses an efficient welding method for a B-type radiating pipe. The efficient welding method comprises the following steps that 1, a copper sheet is placed on a pipe body forming device, a copper material is conveyed into reinforcing rib forming rollers to penetrate through the reinforcing rib forming rollers to be pressed to form a reinforcing rib, the copper material with the reinforcing rib is conveyed to a tin-lead outlet, a tin-lead wire is sprayed on the copper material, the B-shaped pipe is formed through gradual pressing in the pipe body forming rollers, the reinforcing rib is right opposite to a tin lead wire up and down, the B-shaped pipe and fins are arranged at intervals to form a core of a radiator, and pressing fixing is performed, so that the reinforcing rib makes contact with the tin lead wire; and 2, after high-temperature heating, tin and lead are dissolved, so that the reinforcing rib and a pipe body are welded and fixed to form the stable B-shaped pipe. According to the efficient welding method for the B-type radiating pipe, welding of multiple points can be conducted at a time, operation is easy, and efficiency and labor saving are achieved.
