Abstract
This paper presents an experimental research of three different capillary structure technologies of heat pipes for the application in the thermal management of electronic packaging. The first capillary structure is axial grooves manufactured by wire electrical discharge machining (wire-EDM). The sintering process with copper powder produced the second heat pipe. Finally, a hybrid heat pipe was manufactured by the combination of the two previous processes. The heat pipes were produced by a copper tube with an outer diameter of 9.45 mm and length of 200 mm. The working fluid used was deionized water. The heat pipes were tested horizontally to increasing heat loads varying from 5 to 35 W. The experimental results showed that all capillary structures of the heat pipes worked successfully, so the used manufacturing methods are suitable. Nonetheless, the hybrid heat pipe is the best, due to the lowest thermal resistance presented.
