Aluminum radiator

The utility model discloses an aluminum radiator, and relates to the technical field of heat dissipation. The radiator comprises a substrate, radiating fins are fixed on one surface of the substrate,the radiating fins are crisscrossed to form a rectangular grid structure, and notches are arranged on the surfaces of the radiating fins at equal intervals to enable the upper ends of the radiating fins to be small and the lower ends of the radiating fins to be large. The aluminum alloy radiating fin is more beneficial to air circulation, higher in heat exchange efficiency with air, capable of having higher radiating efficiency while not reducing the radiating area of the radiating fin, capable of being integrally formed through aluminum alloy, small in production difficulty and low in production cost. 本实用新型公开了一种铝制散热器，涉及散热技术领域。本实用新型包括基板，基板一表面固定有散热片，散热片纵横交错形成矩形宫格结构，散热片表面等距间隔设有缺口使散热片上端小下端大。本实用新型更加利于空气流通，与空气的换热效率更高，在不减少散热片散热面积的同时，可以具有更高的散热效率，可通过铝合金一体成型，生产难度小，生产成本低。
