Device for heat dissipation and heat dissipation monitoring of motor controller

Abstract

The invention relates to a device for the heat dissipation and heat dissipation monitoring of a motor controller. The device comprises a cooling channel inlet, wherein the bottom of the cooling channel inlet is connected with a first cooling channel and a second cooling channel, the first cooling channel is set to be in a normally open state, the second cooling channel is set to be in a normally closed state, and the first cooling channel and the second cooling channel are connected with the edge joints through triangular ring joint structures. A magnetic block is arranged in the second cooling channel, and the other ends of the first cooling channel and the second cooling channel are connected with cooling channel outlets. A monitoring center is arranged at an outlet of the cooling channel, and a temperature monitoring point is further arranged at the joint of the first cooling channel and the second cooling channel. The device can achieve the effective monitoring of all positions of the motor controller, can achieve a heat dissipation scheme according to a monitoring result, and achieves more efficient and more targeted heat dissipation.

[0002] Electric forklifts use motor controllers to help complete vehicle driving and cargo handling. Due to different working environments and job requirements, some electric forklifts need to use up to ten kilowatts of power to complete the work requirements. Therefore, electric forklift controllers are not only for In addition to the requirements on the power and stability of the battery, the heat dissipation requirements for the motor controller are particularly strict. Traditional motor controllers mainly use heat-conducting silicone grease, and the module aluminum bottom plate is mounted under the controller, and the module bottom plate is matched with a large surface area aluminum bottom plate or equipped with heat dissipation. Fans and other means conduct heat export and guide heat dissipation. The invention patent motor controller radiator with application number 201610707800.6 provides an auxiliary heat dissipation device. Coolant is input into the flow channel and the flow direction is continuously changed by the coolant to form a turbulent vortex, which promotes The disturbance of the boundary layer, this method increases the heat sink part of the auxiliary heat dissipation compared with the traditional method, but this method only realizes the possible increase in heat dissipation from the physical point of view, and does not make any conclusions about the effect of heat dissipation and which part needs to be strengthened. Monitoring and adjustment of heat dissipation schemes based on monitoring results. Therefore, in the existing heat dissipation methods and auxiliary heat dissipation methods, there are still places where heat dissipation is unilaterally enhanced without effective heat dissipation monitoring feedback and heat dissipation is adjusted according to feedback.
