<p>A heat exchange fin of a heat exchanger comprises a base plate (1). The surface of the base plate (1) is wave-shaped. Several through holes (11) matched to the cooling medium pipeline are arranged on the base plate (1). Several louver structures (12) are arranged around the through holes (11) on the base plate (1). By arranging the louver structures (12) on the wave-shaped base plate (1), air can flow toward another side of the base plate (1) by the interspaces between the adjacent louvers (121, 122, 123) of the louver structures (12) when the air flows through the valley of the base plate (1), which prevents an air current vortex from forming. In addition, the air current flow is under conditions of turbulent flow for the change of air flow direction, which benefits heat transfer between the cooling medium pipeline and the air current and improves the heat exchange efficiency of the heat exchanger.</p> |
