摘要：

A novel perfusion method of micro heat pipe(MHP) is presented in this paper. The MHP has length of 26mm, width of 20 mm, and thickness of approximate 2.2mm. The predetermined quantity of perfusion is 25 mu l. Small volume and large capillary force render conventional vacuum perfusion methods quite impractical. In order to realize microscale and high precision of perfusion, the method of combining the vacuum perfusion using peristaltic pump and weight comparison before and after working fluid charging together was used. The charging deviation of the method was less than 2 mu l. And after perfusion and sealing, the thermal performance testing of MHP, which is engineered in LED heap dissipation, was conducted and the input power varied from 1W to 7W. The results show that high power LED can reach the status of heat balance and can work steadily. Therefore, this perfusion method can be used to working fluid perfusion of MHP and makes it feasible that it is used for packaging manufacture of heat pipe.
