液氮温区低温回路热管的实验研究——第二部分:主蒸发器的降温过程

EXPERIMENTAL STUDY OF A CRYOGENIC LOOP HEAT PIPE USING NITROGEN AS WORKING FLUID Part 2: THE TEMPERATURE DECREASE RATE OF THE PRIMARY EVAPORATOR

摘要: 由于低温回路热管工作在深低温区,因而需要研究它的主蒸发器从环境温度即常温向工作温度的降温过程。通过对实验现象的观察,指出了环境漏热和气库容积对主蒸发器降温过程的影响。

Abstract: Cryogenic loop heat pipe（CLHP） is a kind of two-phase heat transfer device that can operate at very low temperature range.Therefore it is necessary to study the temperature decrease rate of the primary evaporator from room temperature to operating temperature.The discussion of the test results is de scribed.
