RÉSUMÉ

A new type of a copper-methanol capillary pumped loop (CPL) with a flat-plate type of evaporator and a flat-plate type of condenser with a porous element is designed, fabricated, and tested. The multi-layer stainless steel meshes and copper meshes are adopted as a capillary structure of the evaporator and condenser, respectively. The start-up, unstable operation characteristics, and heat transfer performance are investigated experimentally. The experimental results show that when heat load is lower than 450 W the system presents good start-up and continuous operation performance. The experimental results also indicate that the CPL has a good heat transfer characteristic with thermal resistance lower than 0.026°C/W.
