Abstract

The utility model is applied to the field of an electromechanical product, and provides a radiator. The radiator comprises at least a bent or folded heat conduction pipe, a heat conduction plate that is connected with one end of the heat conduction pipe, and a plurality of heat radiation fins that are connected with the other end of the heat conduction pipe. The heat radiation fins are clamped on the heat conduction plate. The heat conduction plate comprises a body and a plurality of U-shaped teeth which protrude on the body, are arranged at intervals and are machined and molded with the body into a whole body. According to the radiator, the U-shaped teeth arranged on the heat conduction plate at intervals are different from clamping teeth on a conventional heat conduction plate so as to avoid secondary processing of the clamping teeth since the clamping teeth are arranged closely. The U-shaped teeth on the heat conduction plate can be machined and molded with the body of the heat conduction plate to be the whole body, and are shorter in terms of production cycle and simpler in terms of structure. Moreover, the U-shaped teeth are easier for interference fit to enable more stable connection.
