INSTRUCTION DESCRIPTION α) [Technical Field] The present invention relates to a heat pipe press-sealing method (2), and more particularly to a press-sealing method which can shorten the length of a heat pipe sealing end. [Prior Art] According to the first figure, the sealing structure of the conventional heat pipe 1 a is obtained by first shrinking the nozzle end 1 Oa of the heat pipe 1 a into a shrinking pipe portion 10 Oa. Clamping the end of the shrinkage tube portion 10 a to form a crushing zone 10 1 a, and welding the upper end of the crushing zone 10 1 a (illustration omitted), thereby The nozzle end 10a of the heat pipe la is sealed. ► However, the main purpose of the sealing structure of the conventional heat pipe 1 a is that the nozzle end 10 a is reduced to the shrinkage portion 1 0 0 a, and the volume and area of the sealing structure region of the nozzle end 10 a are advanced. Reduced so that the welding process can proceed. However, although the narrowing of the nozzle end 10 a of the heat pipe 1 a is advantageous for the welding process, it also causes the invalid end of the heat pipe la, especially when the heat pipe la needs to be applied in the case of the heat sink fins. The nozzle end 10 a of the heat pipe 1 a cannot be connected to the fins not only by narrowing the pipe diameter, but also because the nozzle end 10 a must protrude outside the fin group and occupy a space. In view of the above, the present inventors have made an effort to improve and solve the above-mentioned deficiencies, and have finally made a proposal to rationally and effectively improve the above-mentioned defects. SUMMARY OF THE INVENTION The main object of the present invention is to provide a heat pipe sealing and sealing method (2), which can solve the conventional defects, can shorten the length of the heat pipe sealing end, and can also increase the heat pipe through the heat dissipation fins. Quantity, or decrease
