Embodiment Construction

[0012] like figure 1 As shown, the sealing process of the non-phase-change inhibited heat transfer substrate channel mouth, first, on the non-phase-change inhibited heat transfer substrate 1, the pressure of the grid-shaped working medium channel 2 upstream of the filling port 3 is compressed by mechanical force or other external force. The dead zone is pressed to death; then adjust the welding head of the laser welding machine to reach the expected welding position, start the welding program, and the welding head of the laser welding machine will start from the position 3~5mm outside the upstream edge of the filling port 3 according to the preset parameters Welding, in the direction normal to the grid-like working fluid channel 2, do the welding movement of a straight line path, until the welding is stopped at a position 3~5mm away from the other edge of the grid-like working fluid channel 2, and the welding head returns to zero . In this way, a "one"-shaped weld 4 is formed...

Abstract

The invention relates to a sealing process for a non-phase change inhibition heat transfer substrate channel opening. The sealing process includes: using mechanical force or other external force to compress the compression area of the grid working medium channel on the upstream of a filling opening in a non-phase change inhibition heat transfer substrate; adjusting the welding head of a laser welding machine to reach a preset welding part, starting a welding program, and performing straight-line-shaped weld joint welding on the upstream of the filling opening to allow the surface layer and the inner layer of a grid working medium channel to be fused together so as to complete the sealing of the grid working medium channel opening. The sealing process has the advantages that the process is simple and high in welding efficiency, finished products are attractive in appearance and reliable in sealing, and automatic production can be achieved.

Description

technical field [0001] The invention relates to a sealing process after a metal channel is filled with working fluid, in particular to a sealing process for a channel opening of a non-phase-change inhibited heat transfer substrate. Background technique [0002] As an efficient heat transfer component, the non-phase change inhibited heat transfer substrate has a wide range of applications. During its production process, when the working fluid is filled, the opening of the filling groove must be closed quickly to prevent the working fluid from leaking and failing. At present, brazing and welding are usually used to seal, that is, after the filling of the working fluid is completed, the upstream channel of the filling mouth is first pressed to death, and then the filling mouth is welded and sealed by manual flame brazing. Difficulty, low reliability, low production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
