The parallel tube heat transport device with plurality thin tube connecting of cooling headers and heating headers were developed and their performance was experimentally tested. As a result, the parallel tube heat transport device was able to obtain higher heat transport performance than the heat pipe. It has characteristics that working fluid is sealed in the inside of the device, circulation of the working fluid is realized by using phase change, and heat transport is performed. In this study, the influence of the working fluid of the parallel tube heat transport device on the heat transport characteristics was evaluated by the heat transfer experiment. As the working fluid, HFC refrigerant (R134a) and HFO refrigerant (R1234yf) were used. In this study, we conducted experiments with varying posture and enclosed rate.
