Abstract
The disturbance, caused by the boiling phenomena in the inverted meniscus type evaporator, is of great importance in the normal operation of the CPL, especially when the heat load is low. By theoretical and experimental studies on this issue, it shows that the evaporator of the CPL operates in a mode of boiling in the wick. By solving a set of momentum equations, it concludes that, this kind of boiling phenomena in the wick cause no notable negative influence on the normal performance of the CPL, although there really exists some adverse influence during the CPL start-up. Additionally, the causes of the dry-out of the evaporator under low heat load are conducted in the paper. The conclusions are verified by subsequent experiments. More details about the experiments are also described in the paper.
