Comparing to other cooler with active cooling ability, TMC is very compact, light-weighted, and quite suitable for transporting the medicines such as serum, vaccine etc. which are very sensitive to temperature variation. 　　In this study, the efforts were focused on the improvement of cooling performance for a TMC. The sheet metal, attached to the cold end of thermoelectric module（TEM）, used to cool down the indoor air is assumed to be a symmetrically extended single fin. The optimized thickness of the sheet metal is then obtained. In the analysis of multiple fin module which is attached to the hot end of TEM, the optimized fin spacing is obtained by maximizing the heat released by a single subchannel. 　　Tests with and without optimization on heat sink were also conducted in this study to examine the difference in cooling performance. Under the simulated full-load condition, the cooling time required to cool down the indoor temperature from 27℃ to 6℃ is found to be 83 vs 108 minutes for the case with vs without optimal fin spacing, and the COP of TMC when the indoor temperature is kept at 6℃ is found to 0.08 vs 0.05 for the case with vs without optimal fin spacing.
