<p>PURPOSE:To improve the heat conductive efficiency by preliminarily inserting the plug to the opening end for discharging the air from the vessel, welding the plug at the same time of sucking the air, and making the discharge hole airtight completely. CONSTITUTION:In the device that the air is discharged from the metallic vessel (heat pipe) 1, at the same time, the air discharge hole 5 and its plug 2 of this vessel are projection-welded through the electrodes 3 and 6 of moving side and fixing side and the vacuum is sealed, the air discharge hole 5 for sucking the air from the vessel 1 is set at either one hand electrode, connected to the vacuum pump and the space between the moving side electrode 3 and fixing side electrode 6 are connected with the flexible and airtight member of the bellows 11, etc. Therefore, the original shape of pipe 1 can be left as it is, the heat exchanging liquid is effectively transmitted till the top end of the pipe, and the heat conductive efficiency can be improved.</p> |
