AB - A thermal shielding radiator, which has an extra cuboid cavity between channels and sealplate, is proposed to achieve a large temperature difference between the hot and cold surfaces and high temperature uniformity on the cold surface. To get uniform distribution of the flow inside each channel, the thermal shielding radiator with different inlet/outlet types (namely C-, Z-, Y- and I-type) are numerically simulated. It is found that I-type has the best performance in velocity uniformity. Due to the cavity, the temperature difference between two sides of the thermal shielding radiator improves significantly. Besides, the mini-channel with equidifferent fin thickness is also proposed, and more uniform flow and the temperature distribution on the cold surface are achieved. Moreover, effect of geometry, operating parameters on the flow and heat transfer performance for both the thermal shielding radiator and the heat radiator are studied and compared.
