Study on a Novel Separating Flat Heat Pipe Radiator

Abstract:

A novel separating flat heat pipe radiator was developed for high power rectification equipment，the physical and mathematic heat transfer model was built; The influences of the charging ratio, coil diameter and interbank combination on heat transfer limitation and temperature uniformity were researched; The characteristics of heat transfer system with four different kinds of interbank combinations between the new type of heat pipe and the common were analyzed . The results indicate that the heat transfer limitation and temperature uniformity of the new type of heat pipe can be improved when the charging ratio and the interbank combination were at the high-points. The charging ratio is in the range of 125%-175%，the interbank combination of the heat pipe heat sink is 4×10mm，the junction temperature of high power rectification equipment can be controlled steadily under 25°C for the heat load of 620W，and shall be very promising heat—transfer devices for controlling junction temperature of high power rectification equipment．
