Type of article: Article, IJR article

Summary

Firstly, a brief review of the MPCL system design and work principle is presented and a proposed experimental system is described. Special attention was paid to the system start-up and dynamic working characteristics under different conditions such as heat load variation, mass flow rate or sinusoidal temperature variation of boundary condition. According to the experimental findings, the transient liquid transfer between the main loop and accumulator was analyzed to explain the transient phenomena during the experiments. From the experiments, it was demonstrated that the system presents a good performance and has more stable characteristics for start-up processes and normal operation than the heat pipe, CPL or LHP system. The paper presents MPCL system has self-adjusting ability. Because the accumulator, which is just like the ''brain'' of the system, determines stable capability, and each action of the vapour-liquid interface in it could cause the temperature or pressure change of the evaporator.
