| Abstract(J) | 自励振動ヒートパイプ（OHP）は，薄型軽量な高熱拡散デバイスとして注目されている．本研究ではモビリティへの適用を目指し，次世代低GWP冷媒R474Bを封入したOHPの熱輸送性能を実験的に調査した．内部圧力や管壁温度の計測，および他冷媒との比較を通じて，冷媒物性の違いがOHPの熱輸送性能に与える影響を評価した． Translation |
| Abstract(E) | Oscillating heat pipe (OHP) have attracted attention as thin, lightweight, and high-heat-spreading devices. This study aims to apply OHPs to mobility applications and experimentally investigates the heat transport performance of an OHP filled with R474B, a next-generation low-GWP refrigerant. Through the measurements of internal pressure and tube wall temperature, as well as comparisons with other refrigerants, the effects of differences in refrigerant properties on the heat transport performance of the OHP were evaluated. |
