Low-flow-resistance high-heat-exchange corrugated plate based on bionic sharkskin surface

Abstract

The invention belongs to the technical field of heat dissipation devices, and particularly discloses a bionic sharkskin surface-based low-flow-resistance high-heat-exchange corrugated plate which comprises a heat exchange plate, a plurality of corrugations are arranged on both sides of the heat exchange plate, a plurality of bionic sharkskin micro-nano structures are arranged on each corrugation, a cold flow inlet and a hot flow outlet are formed in the inlet end of the heat exchange plate, and a plurality of bionic sharkskin micro-nano structures are arranged at the outlet end of the heat exchange plate. A cold flow inlet and a hot flow inlet are formed in the inlet end of the heat exchange plate, a cold flow outlet and a hot flow inlet are formed in the outlet end of the heat exchange plate, the cold flow inlet and the cold flow outlet are located on the same side, and the hot flow inlet and the hot flow outlet are located on the same side. And the other structure surrounds the heat flow inlet, the heat flow outlet and the corrugations. By designing the sharkskin-imitating surface with the unique micro-groove type scale structure, fluid resistance can be effectively reduced, meanwhile, a certain regulation and control effect can be generated on fluid flowing, and the corrugated plate sheet with low flow resistance and high heat exchange performance is formed.
