Abstract
Heat pipe is a device of high heat-conduction. It mainly uses inside fluid to convey heat energy while the phase is changing. It’s a tool which can transmit a large amount of heat energy in operating temperature while phase is changing. Therefore, heat pipe also named the superconductor. Using heat pipe transmit the heat energy of the heater source to outside, it is not only solving the problem of heat elimination in small space but also noiseless, and it does not need to offer extra energy. Heat pipe is presently applying to the cooling of the electric equipment, and it uses extremely extensively. So, it’s very important to measure the performance of heat pipe. The major purpose of this study analysis the condenser parameters of Heat Pipe Performance Test Instrument (HPPTI) which affects the accuracy of the heat pipe performance. The study is aimed at discussing with the heat loss problems of HPPTI and the model of thermal resistance. Improving the section of water-cooling structure could increase the efficiency of heat remove, and reduce the heat loss problem in measuring process. It also could keep the heat loss of HPPTI under 10% and accurately measure the temperature inside the heat pipe and the thermal resistance in the condenser. Hence, it could increase the accuracy of HPPTI. Moreover, setting up an equipment named ” TEC controller ” (Thermoelectric Cooling Chip Controller) to measure the condenser section of HPPTI, which can exactly control the temperature in adiabatic section and condenser section. Therefore, it is effective to reduce the experimenting time and increase the accuracy of HPPTI. Key word: Heat Pipe、heat loss、Maximum Heat Transfer 、Thermoelectric Cooling Chip
