HYSTERESIS PHENOMENA IN FLAT-TYPE LOOP HEAT PIPE

ABSTRACT
Testing of loop heat pipes showed that the heat-load dependence of the operating temperature was not always unambiguous. It may have hysteresis phenomena. The temperature hysteresis had a certain relationship with previous history of the power variation, and also related to the initial parameters of the loop heat pipes. It has been found that the temperature hysteresis of the loop heat pipes was related to the gas-liquid distribution in the compensation chamber which depended on the interaction between heat leak of evaporator and the reflux liquid from condenser. The temperature of the loop heat pipes evaporator rose with the gas phase in the compensation chamber increased.
