Abstract
Abstract
In the two-phase mechanically pumped cooling loop, the performance of the evaporator is very important as it directly contacts with the electronic equipment to absorb the waste heat. The evaporator with the micro channels which can enhance heat exchange is designed and it can be used to dissipate the heat generated by the electronic equipment with discrete heat sources. The effects of working medium flow rate and heating power on the performance of the evaporator were analyzed through numerical simulation. Meanwhile, the changes of evaporator performance were also investigated while the heating power changed periodically and suddenly. In addition, the flow and heat transfer process in the evaporator at the initial stage were analyzed by transient calculation. The results showed that the evaporator with micro channels can reduce the maximum temperature by 47.66% and the maximum temperature difference by 83.39% compared with the evaporator without micro channels. In addition, the evaporator showed good stability under variable power condition.
