Using Thermoelectric Cooling Chip (T.E.C.) to improve the stability of the Heat Pipe Performance Test Instrument

Heat pipe is a device of high heat-conduction. It mainly uses inside fluid to carry 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. The major purpose of this study is to analyze the affect of the condenser parameters to Heat Pipe Performance. A T.E.C. controller (Thermoelectric Cooling Chip Controller) to measure the condenser section of HPPTI (Heat Pipe Performance Test Instrument) is developed in this study, which can exactly control the temperature in adiabatic section and condenser section very accurately. The experimental results show the maximum heat loading controlled by T.E.C. is the same as that of controlled by water cooling, but the test time is reduce from 7 hours to 3.5 hour, and the final target for test time we expected will be achieved within 20 minutes.
