Description

Technical Field

[0001] The present invention relates to the technical field of motor drive controllers, and in particular to a motor drive controller with multiple heat dissipation modes. Background Art

[0002] The motor controller is an integrated circuit that actively controls the motor to operate in a set direction, speed, angle, and response time.

[0003] In electric vehicles, the function of the motor controller is to convert the electric energy stored in the power battery into the electric energy required to drive the motor according to the gear position, throttle, brake and other instructions, to control the start-up, forward and backward speed, climbing strength and other driving conditions of the electric vehicle, or to help the electric vehicle brake and store part of the braking energy in the power battery. It is one of the key components of electric vehicles.

[0004] The motor controller in the prior art needs to carry a large number of operating instructions during use, so the internal structure and control equipment need to achieve efficient heat dissipation to maintain stable and safe control and use. The traditional heat dissipation method is to open heat dissipation holes or air cooling. First of all, the heat dissipation method is relatively single in function, and the heat dissipation effect required for different weather and transportation time is different. Therefore, it is impossible to complete different adjustment controls as required. When the controller temperature is too high and the heat is not dissipated efficiently in time, it is very easy to cause damage to the controller, thus affecting the use effect and life.

[0005] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "lightweight and high heat dissipation motor controller" with application number "202122710657.5". The patent mainly sets a small liquid storage tank, condensate, a liquid pump, a liquid inlet pipe, a heat sink, a cavity, a thermal grease layer, a liquid outlet pipe, a cooling box and an overflow pipe. The heat dissipated by the motor controller body can be quickly conducted through the thermal grease layer to transfer the heat to the heat sink. At this time, the liquid pump works to extract the condensate in the small liquid storage tank and send it into the cavity in the heat sink through the liquid inlet pipe. After the condensate fills the cavity, it can quickly absorb the heat on the heat sink. After absorbing the heat, the condensate with increased temperature flows out from the liquid outlet pipe to the cooling box for natural cooling. However, the heat can be cooled by the condensate, but the discharged heat needs to pass through a fixed heat dissipation port, and it is not convenient to utilize the generated heat when the weather temperature is low. The patent may still have limitations in use. Therefore, according to the applicant's invention, a motor drive controller device capable of multiple heat dissipation modes is invented, which solves the problem of the singleness of the controller in heat dissipation use. Summary of the invention

When the cooling liquid flows through the cooling pipe 3010, the driving motor 6 continuously introduces external gas through the effect of cold air, and the gas contacts the cooling pipe 3010 to achieve a cooling effect. The cooled gas flows into the interior of the controller housing 1 to achieve a rapid cooling effect. At the same time, the small motor 7 drives to drive the rotation of the threaded rod 701, and the threaded rod 701 A fixed threaded sleeve 702 is sleeved on the outside. Due to the fixing effect of the fixed threaded sleeve 702, the thread of the fixed threaded sleeve 702 can be kept rising, and the fixed top plate 202 is lifted up, so that more heat dissipation holes 204 are exposed, and the gas can be quickly discharged to achieve efficient heat dissipation effect; when heat is dissipated in winter, the cooling box 3 structure can be stopped, and the driving motor 6 introduces external air.
