Treatment method of heat conduction pipe

Abstract

The invention discloses a treatment method of a heat conduction pipe. The treatment method of the heat conduction pipe is used for carrying out flattening or bending treatment on the heat conduction pipe with an opening at one end, and the treatment method comprises the following steps that S1, the heat conduction pipe is placed at a position to be treated; S2, a gas pressurizing assembly is connected to one end of the heat conduction pipe; and S3, flattening or bending treatment is carried out on the heat conduction pipe, and inflating the heat conduction pipe in the flattening or bending process is carried out so shat the fact that wrinkles are generated on the heat conduction pipe in the flattening or bending process can be prevented. The treatment method of the heat conduction pipe issimple in process, gas is introduced into the heat conduction pipe when the flattening or bending operation is carried out on the heat conduction pipe, and due to the fact that the pressure intensityin the heat conduction pipe has a supporting effect on the pipe wall, the bad appearance that the pipe wall is sunken when the heat conduction pipe is flattened or wrinkled when the heat conduction pipe is bent can be prevented.

Description

technical field [0001] The invention belongs to the technical field of heat conduction pipes, in particular to a processing method for heat conduction pipes. Background technique [0002] During the processing and production of the heat pipe, it is often necessary to flatten or bend the heat pipe to increase its usable area and reduce its occupied space. Existing processes for flattening or bending heat pipes usually use mechanical extrusion, for example, as figure 1 As shown, the existing heat pipe bending assembly 1 is composed of a bending round wheel 1a, a clamp block 1b and a baffle plate 1c, and the steps of bending the heat pipe include: (1) first positioning the heat pipe by the clamp block 1b on the bending wheel 1a; (2) Then, use the baffle plate 1c to bend the ultra-thin heat pipe along the bending surface of the bending wheel 1a. However, due to the limitation of the bending angle and bending radius in the existing bending process, the tube wall of the heat pip...

Problems solved by technology

However, in the existing bending process, due to the limitation of the bending angle and bending radius, the tube wall of the heat pipe will produce many wrinkles, which will affect the appearance of the tube.

[0003] In order to avoid the depression of the tube wall of the heat conduction tube during processing, various methods are usually adopted to prevent it. For example, the existing heat conduction tube flattening process usually adopts the following methods: Heating on the heating table; then, after the internal gasification pressure of the copper tube is increased, the copper tube is placed on the surface of the preheating press for flattening, and the high pressure inside the tube is used to prop up the tube wall to ensure that the copper tube is flattened after being flattened. The wall does not sag, but this process has defects such as complicated operation steps and high-temperature heating, which poses safety hazards.
