An air-liquid hybrid refrigeration motor controller

Abstract

The invention discloses an air-liquid mixed refrigerated motor controller and relates to the technical field of a motor controller. The air-liquid mixed refrigerated motor controller comprises a housing. One inner wall of the housing is fixedly provided with an air blower; one end of an air outlet of the air blower is fixedly provided with an air pipe; one surface of the housing is fixedly provided with a fixation plate; one surface of the fixation plate is provided with a plurality of slots; and one surface of the fixation plate is fixedly provided with a first water tank. Air is supplied tothe housing through the air blower to discharge the rising heat in the housing from the slots; meanwhile, the rising heat is conducted through a plurality of heat conduction sheets on the first watertank allow the heat conducted by the heat conduction sheets to exchange heat with the water circulating in the first water tank; through mutual cooperation of the air blower and the water flowing in the first water tank, heat dissipation efficiency in the housing is allowed to be higher; and through combination of a PLC controller and a temperature sensor, working efficiency of the air blower, anair pump and a water pump can be adjusted in time, and heat dissipation efficiency of the motor controller can meet use requirements according to actual needs.

Description

technical field [0001] The invention belongs to the technical field of motor controllers, in particular to an air-liquid mixed refrigeration motor controller. Background technique [0002] In the production process of traditional hybrid electric vehicles, the inverter module is generally used to control the operation of the drive motor and generator, and in the process of using the inverter module to control the operation of the drive motor and generator, the inverter module needs to be controlled by the motor controller. Corresponding control, so as to complete the effective work of the car drive motor and generator. The motor controller will generate a lot of heat during the corresponding control process, and the accumulation of heat will affect the operating efficiency of the motor controller, thereby affecting the normal operation of the motor, making the car unable to continue driving. [0003] The heat dissipation of the existing motor controller is generally provided...

The motor controller will generate a lot of heat during the corresponding control process, and the heat accumulation will affect the operating efficiency of the motor controller, thereby affecting the normal operation of the motor, making the car unable to continue driving

[0003] The heat dissipation of the existing motor controller is generally provided with multiple heat sinks outside the controller, and the heat generated by the heat sink is used to conduct the heat generated by the motor controller to cool down. In this process, the heat dissipation efficiency of the heat sink is limited, and the heat dissipation effect varies with The increase of time gradually deteriorates, which cannot meet the heat dissipation requirements of the motor controller, thereby reducing the operating efficiency of the motor controller; at the same time, when the existing motor controller uses water to cool down, the contact between the water and the motor controller The surface is small, which affects the heat dissipation efficiency of the motor controller to a certain extent; finally, the existing heat dissipation device of the motor controller cannot cool the water after heat absorption in time, so that the heat absorption capacity of the water in the next heat exchange is reduced. Thus affecting the heat dissipation effect of the motor controller
