Modular water-cooling structure of motor controller

Abstract

The invention discloses a modular water-cooling structure of a motor controller. The modular water-cooling structure comprises an IGBT (insulated gate bipolar transistor) module, sealing screws, waterjoints, a modular water cooling plate and sealing rings, wherein the IGBT module is fixedly mounted on the surface of the modular water cooling plate; a water channel cavity is formed in the modularwater cooling plate, a plurality of water inlets communicated with the inside water channel cavity are formed in one end of the modular water cooling plate, and a plurality of water outlets communicated with the inside water channel cavity are formed in the other end; and during actual use, one or more water inlets and water outlets are selected to be connected with the water joints, and the remaining water inlets and water outlets are sealed by the sealing rings and the sealing screws. As for motor controllers with different power, a standard water channel structure meets the heat dissipationdemands, and repeated design and simulation verification work of water channels are avoided; and the modular water channel structure comprises five water inlets and water outlets, the water inlets and the water outlets of the modular water channels are reasonably selected according to the structure of the controller and the water inlet and outlet positions, and the structure is flexible and variable in design.

Description

technical field [0001] The invention relates to a motor controller, in particular to a modularized water cooling structure of the motor controller. Background technique [0002] At present, the common motor controller modular water-cooling structure is that the controller housing and the water-cooling system are integrated. In individual cases, the IGBT and the water channel are welded together separately, and there is only one water inlet and outlet. The disadvantages of the prior art are: [0003] 1) Commonly used motor controller water channels and housings are integrated. Each controller and water channel structure is unique. Every time a new controller is developed, its water channel structure will be similarly adjusted, and the mold will be re-opened, resulting in cost changes. high. [0004] 2) For new development projects, products need to be redesigned and verified, increasing the design cycle. [0005] 3) If the water channel of the commonly used controller is ...

Problems solved by technology

[0003] 1) Commonly used motor controller water channels and housings are integrated. Each controller and water channel structure is unique. Every time a new controller is developed, its water channel structure will be similarly adjusted, and the mold will be re-opened, resulting in cost changes. high

[0004] 2) For new development projects, products need to be redesigned and verified, increasing the design cycle

[0005] 3) If the water channel of the commonly used controller is deformed or bulged, the entire controller needs to be replaced, and there is no maintainability

[0006] 4) Commonly used controller waterway integrated structure or waterway and module integrated structure are only suitable for a certain type of controller, and the substitutability is low
