When forced air cooling is adopted, the radiator with the traditional radiating rib structure is more and more difficult to meet the radiator demand, and the structural characteristics of the radiator enable the radiator with the power converter rectifying module to be large in size and weight.
At present, more and more radiators of domestic and foreign similar high-power converter rectification modules adopt a tooth-buckling fin structure radiator (tooth-buckling fins are formed by connecting two adjacent small fin blocks through a lap joint structure, wherein tooth-buckling refers to a fin connecting mode, and the sectional shape of the fin is not the sectional shape of the fin), but the tooth-buckling fins are poor in heat conduction performance in the height direction (namely, the heat conduction performance between the upper end face 201, close to a heat source, of the tooth-buckling fins 2 and the lower end face 202, far away from the heat source, of the tooth-buckling fins is poor in heat conduction performance in the section, the heat conduction distance is used for describing the heat conduction performance in the height direction of the tooth-buckling fins 2. Because the single fin is thinner, the conventional thickness is about 0.2-0.4 mm, and the efficiency of heat transfer from a near heat source face to a far heat source face is low).

According to the utility model, the heat pipe component is added, so that the heat is efficiently transferred to the lower end face of the tooth-buckling fin by utilizing the high heat conductivity of the heat pipe, and the heat dissipation efficiency of the radiator is effectively improved. Meanwhile, the structure of the base frame and the mounting strip is utilized, so that the structural strength of the tooth-buckling radiator is effectively improved.
