ベンド部を有するヒートパイプの熱輸送性能(オーガナイズドセッション9 マイクロマシン/電子デバイスにおける伝熱問題)
詳細
The maximum operating heat transfer rate of heatpipes with bend was investigated. In this paper evaporation part of the heatpipe was heated with uniform heat flux by flexible sheath heater, instead of cartridge heater with heater block in previous work. We measured temperature profile of several point on evaporation part wall of the heatpipe. The results show the dryout begins at the middle of evaporation part. We confirmed that the correlation representing the flooding limit by taking the influence of the heatpipe height agrees with the experimental results on bended heatpipe heated with uniform heat flux.
