Abstract: Shovel tooth technology is a kind of shovel chip machine to cut a whole piece of aluminum or copper into a standard spacing, a certain thickness of products New material processing technology, can be applied in the radiator field. Uses Coil Designer to make simulation comparison, and analyzes the heat dissipation effect of shovel tooth radiator and microchannel radiator under the same conditions. The results show that compared with the microchannel radiator, the heat dissipation effect is better, the surface temperature distribution is more uniform, and there is no obvious dust attachment on the surface, which provides the test data and reference basis for the selection of the main engine heat exchanger.

Key words: Tooth dissipation, Test comparison, Simulation comparison, Heat dissipation performance
