摘要：

The 2D model for the small-scale flat capillary pumped loop (CPL) evaporator is presented, and the entire evaporator is solved with SIMPLE algorithm as a conjugate problem. The effect of heat conduction of side metallic wall on the performance of evaporator is analyzed, and the side wall effect heat transfer limit of flat evaporator is introduced. The numerical results show that the heat transfer capacity can be improved not only by redusing the height of the compensator and the thickness of the side wall and the bottom wall but also by increasing the height of the capillary wick.
