Problems solved by technology

The low-voltage control box of new energy vehicles usually lacks an effective heat dissipation structure, the heat dissipation efficiency is low, and it is easy to cause fire, etc. Therefore, it is necessary to provide a low-voltage control box for new energy vehicles. The patent includes a control box shell and a control box bottom plate arranged at the bottom of the control box shell, the open end of the control box shell is set towards the control box bottom plate, and the top two ends of the control box shell are provided with Two heat dissipation chambers, the top of the heat dissipation chamber is provided with a motor mounting seat, the motor mounting seat is provided with a motor, and the side wall of the heat dissipation chamber facing the inside of the control box housing is provided with a wiring hole. Two power supply fixtures are arranged symmetrically above the inside of the control box housing between the two heat dissipation chambers. The power supply fixtures include a connecting column vertically connected to the top of the control box housing, and connected to The end of the column, the bearing plate extending to the inside of the control box housing, the bearing plate is provided with a power supply, the motor is connected to the power supply through the wiring hole, the output shaft of the motor is connected to a fan, The air outlet direction of the fan is towards the bottom of the control box housing, the bottom of the heat dissipation chamber is provided with an air outlet corresponding to the air outlet direction of the fan, the bottom of the heat dissipation chamber is provided with a guide plate, and the air guide The plate is inclined to the outside of the control box housing, the front of the control box housing is provided with a main heat dissipation net cover corresponding to the position of the power supply, and the end surface of the control box housing is provided with an auxiliary heat dissipation grill at the position corresponding to the deflector. Net cover, although the structure of this invention is simple, there are many deficiencies and defects. In the existing equipment, the design of the fan has defects. It is good, and the fan is in the control box. Once it is damaged, it will be inconvenient to replace and repair, which will increase the workload of the staff, make the staff easy to feel physical fatigue, and at the same time reduce the work efficiency. In view of these situations, in order to avoid the above technical problems, It is indeed necessary to provide a heat dissipation device for the low-voltage control box of a new energy vehicle to overcome the defects in the prior art
