Abstract�� The heat transfer enhancement effect of the metal foam has been verified by dozens of researches. In order to test the cold charging effect, a new type of high-efficiency energy storage devices was made up by composite phase change material(PCM), which was consisted of copper foam (the heat transfer enhancement) and water. Via experimental study, the heat preservation effect of the devices in the refrigeration equipments was simulated. The model was set up and calculated through quasi-stable state method, and the results meet the test results very well. The cold charging process of the new type energy storage devices was approved to be faster and more adequate compared to the traditional energy storage devices. The entire heat transfer velocity and energy storage efficiency are obviously improved, which promises a good prospect in the refrigerated transportation.
Keywords�� heat transfer   phase change materials(PCM)   copper foam   cold storage   refrigerated containers
