摘要：
Loop heat pipes (LHP) have great application prospects in the cooling of electronic elements duo to their compactness and high efficiency. This paper designed a compact LHP with capillary core flat-over evaporator and investigated its start-up and heat transfer performance under various conditions experimentally. The results show that a higher heating power and higher refrigerant charge are beneficial with the LHP starts up stably, while it happens oscillation during the start-up process with low heat load and charge ratio. As for the heat transfer performance, there is an optimal refrigerant filling ratio corresponding to the heat load where the LHP shows the best cooling performance. The optimal filling ratio is small when the heat load is relatively low, and the performance will be better if the refrigerant charge is relatively large under a condition with high heat load. © 2021, Editorial Board of CIESC Journal.
