Abstract

The invention discloses an IGBT heat radiator, which comprises a water-cooled plate, a cooling fan and a plate fin-type heat radiator, wherein the front side of the water-cooled plate is matched with an IGBT module; the plate fin-type heat radiator is fixedly arranged on the back side of the water-cooled plate; the plate surface of the plate fin-type heat radiator is tightly fit with the back side of the water-cooled plate; the second interface of the water-cooled plate is communicated with the first interface of the plate fin-type heat radiator; the cooling fan is arranged at one side of the plate fin-type heat radiator; and a water pump is arranged between the first interface of the water-cooled plate and the second interface of the plate fin-type heat radiator. According to the IGBT heat radiator, through fit arrangement between the water-cooled plate and the plate fin-type heat radiator, heat generated by the IGBT module can be transmitted to the plate fin-type heat radiator through forced water cooling and heat conduction modes, in a condition with small heat radiation requirements, even without water circulation, the heat generated by the IGBT module can be transmitted to the plate fin-type heat radiator through the heat conduction mode, the heat transmission efficiency and the heat radiation efficiency are improved, the operation energy consumption is reduced, the structure is compact, and the occupied space is small.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to an IGBT radiator. Background technique [0002] At present, cooling equipment is required to be installed on the converters of electric locomotives to dissipate heat from the IGBT (Insulated Gate Bipolar Transistor) module, so as to ensure the normal operation of all related equipment. Among them, such as figure 1 As shown, the cooling device is usually a water-cooled plate 01, and the IGBT module is mounted on the water-cooled plate 01. The cooling water is forced to pass through the water tank under the panel to take away the heat generated by the IGBT module. In addition, a plate-fin radiator, Fans, water pumps, pipelines and other components dissipate the heat contained in the water to the air through forced convection through the plate-fin radiator. [0003] However, the equipment of this cooling method takes up a lot of space and consumes a lot of energy for operation. ...
