High-efficient molded heat radiator for drive motor controller of automobile

Abstract

The invention provides a high-efficient molded heat radiator for a drive motor controller of an automobile. The heat radiator comprises a radiator main body which is molded in an integrated manner, the front surface of the heat radiator main body is divided into a power module mounting section and a capacitor mounting section, a W-shaped heat radiating water passage is arranged at the rear surface of the heat radiator main body at the position corresponding to the power module mounting section, a plurality of heat radiating grooves are formed in the heat radiating water passage, and the two end parts of the heat radiating water passage are respectively connected with a water inlet pipe and a water outlet pipe. The heat radiator disclosed by the utility model is molded in an integrated manner, the mounting is simple and convenient, and the heat radiator can be processed completely in a disposable manner; only two ends of the W-shaped heat radiating water passage are connected with the water inlet pipe and the water outlet pipe, the risk of water leakage does not occur, the heat exchanging area is enlarged by the heat radiating grooves in the heat radiating water passage, and the heat radiating effect is better.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of a power module of a high-power motor controller for a vehicle, in particular to a high-efficiency molded radiator for a motor controller of a vehicle drive. Background technique [0002] The heat sink of the power module of the existing high-power motor controller for vehicles is difficult to assemble, there is a risk of water leakage, and the relative position of other parts such as capacitors is prone to deviation. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention provides a high-efficiency molded radiator for automobile drive motor controller, which includes an integrally formed radiator main body, and a semi-closed cooling water channel is provided on the back of the radiator, and the two ports of the water channel are connected to the water inlet and outlet pipes , There is no risk of water leakage, the main body of the r...
