Abstract: The capillary pump loop (CPL) has a strong capacity of heat dissipation. But it is interfered by many external factors when it works. In order to study the operating characteristics of CPL in different complex conditions, this paper varies the working fluid, initial vacuum, evaporator inclination, the relative height between the evaporator and condenser, and the relative position between the two. Stability test is carried out in the end. Through the experiment, it can be concluded that ethanol is selected as working fluid; the CPL achieves better performance when the initial vacuum was less than 1,000 Pa; the evaporator inclination and relative height have little impact on the heat transfer performance of CPL; beyond the anti-gravity situation, the CPL exhibits excellent heat transfer performance with the variation of the relative position. The CPL exhibits a decent stability and reliability performance after long time operating.
