Description

Technical Field

[0001] This invention relates to the field of new energy vehicle motor control technology, specifically a new energy vehicle motor control unit with a cooling device. Background Technology

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] The automotive motor controller is a control unit that controls the electric motor to drive the vehicle. It is a core component of electric vehicles and features CAN communication, overcurrent protection, overload protection, undervoltage protection, overvoltage protection, phase loss protection, energy feedback, power limiting, voltage interlock, and fault reporting. Motor controller technology is currently quite mature, characterized by high integration, high power density, long lifespan, and stable output.

[0004] However, the motor control unit of new energy vehicles is generally cooled by air, which is not very effective. If water cooling is used, the water will be at a high temperature after long-term use, which will affect the cooling of the motor control unit of the new energy vehicle. Summary of the Invention

[0005] The purpose of this invention is to provide a new energy vehicle motor control unit with a cooling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a new energy vehicle motor control unit with a cooling device, comprising: a control box, the surface of which is provided with a fixing frame; a cooling box, the top of which is provided with a limit block, the surface of which is provided with an extension plate, the surface of which is provided with a fan, the interior of which is provided with a slot, in which a first cooling plate and a second cooling plate are provided; and a water pipe provided on the surface of the cooling box.

[0007] Preferably, the cooling box is located at the bottom of the control box, the limiting block is clipped onto the surface of the control box, and a screw is inserted into the fixing bracket to fix the control box and the cooling box. The bottom of the cooling box is provided with a rubber strip and a reinforcing rod.

[0008] Preferably, the rubber strips and reinforcing rods are in multiple sets, and the multiple sets of rubber strips and reinforcing rods are evenly distributed at the bottom of the cooling box, and the rubber strips and reinforcing rods are distributed adjacent to each other. A water collection tank is provided inside the cooling box, and the water collection tank is connected to a water pipe.

[0009] Preferably, a heat dissipation pipe is provided in the slot, the interior of the heat dissipation pipe is connected to the water collection tank, the interior of the heat dissipation pipe is filled with coolant, a contact plate is provided at the top of the heat dissipation pipe, the interior of the contact plate is hollow and is connected to the interior of the heat dissipation pipe, two sets of cylindrical grooves are provided on the surface of the heat dissipation pipe, and a first cooling plate and a second cooling plate are provided at the bottom of the heat dissipation pipe.

[0010] Preferably, the first and second cooling plates are arc-shaped, and heat dissipation plates are provided inside the first and second cooling plates. The heat dissipation plates are connected to the interior of the heat dissipation pipes, and the interior of the contact plate and the heat dissipation plates are filled with coolant.

[0011] Preferably, the first cooling plate is located at the bottom of the middle part of the heat dissipation pipe, the second cooling plate is located at the bottom of the end of the heat dissipation pipe, and the first cooling plate and the second cooling plate are distributed alternately.

[0012] Preferably, a first baffle and a second baffle are installed inside the slot, and the surfaces of the first baffle and the second baffle are provided with holes.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In this invention, the cooling box is placed at the bottom of the control box, and the limiting block is clipped onto the surface of the control box. The control box and the cooling box are simultaneously fixed by screwing them onto the surface of the fixing frame. The bottom of the cooling box is equipped with rubber strips and reinforcing rods. The reinforcing rods strengthen the bottom of the cooling box, and the rubber strips prevent slipping. Coolant flows through the inside of the cooling box via water pipes. A contact plate is provided at the top of the heat dissipation pipes to increase the contact area with the surface of the control box. The surface of the contact plate has cylindrical grooves to increase the contact area between the contact plate and the air. A heat dissipation plate is provided at the bottom of the contact plate to increase the cooling speed of the coolant inside the contact plate. A fan draws air into the interior of the cooling box. The air is blown onto the surfaces of the first and second cooling plates by the obstruction of the first and second baffles, causing the coolant in the heat dissipation plates to cool down rapidly.
