DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: an efficient heat dissipation system for an electric vehicle motor, comprising an installation box 1, a ventilation duct 5, a limit movable plate 6, a filter screen 7, a ventilation hole 10, a cooling circulation pipe 11, a circulating water pump 12 and a fixed frame 15, a top plate 2 is fixed on the upper end surface of the installation box 1, a cooling water tank 3 is fixed on the upper end surface of the top plate 2, a water injection port 4 is provided on the upper end surface of the cooling water tank 3, a ventilation duct 5 is fixed on the left end surface of the installation box 1, a fan 14 is installed inside the ventilation duct 5, a fixed frame 15 is fitted and connected to the inner wall of the ventilation duct 5, the fixed frame 15 is movably connected to the limit movable plate 6 inside and extends out of the fixed frame 15, a return spring 13 is provided between the limit movable plate 6 and the fixed frame 15, and a filter screen 7 is installed inside the fixed frame 15;

[0020] A mounting plate 8 is fixed to the lower end surface of the mounting box 1, a motor body 9 is fixed to the front end surface of the mounting plate 8, a circulating water pump 12 is fixed to the lower end surface of the cooling water tank 3, a cooling circulation pipe 11 is arranged between the input end of the circulating water pump 12 and the cooling water tank 3, and a ventilation hole 10 is opened on the right side of the mounting box 1. This design dissipates heat for the motor by combining coolant and fan 14, which greatly improves the heat dissipation efficiency of the motor and ensures the normal operation of the motor. It is stable as a whole, easy to use, and suitable for popularization and use.

[0021] As a first embodiment of the utility model: a movable hole is opened inside the fixed frame 15 and the ventilation duct 5, the specification of the movable hole matches the specification of the limit movable plate 6, and the two can be fitted and slidably connected. The design extends the limit movable plate 6 out of the movable hole, so that the limit movable plate 6 can limit the position of the fixed frame 15, the specification of the fixed frame 15 matches the specification of the ventilation duct 5, and the outer wall of the fixed frame 15 can be fitted and slidably connected with the inner wall of the ventilation duct 5. The design fits and slides the fixed frame 15 with the ventilation duct 5, so that the fixed frame 15 can be inserted into the ventilation duct 5;

[0022] There are multiple groups of ventilation holes 10, which are equal in size and equidistantly arranged on the right side of the installation box 1. A sealing gasket is arranged between the cooling circulation pipe 11 and the cooling water tank 3, and a sealing gasket is arranged between the cooling circulation pipe 11 and the circulating water pump 12. The middle section of the cooling circulation pipe 11 is arranged as a surrounding structure, and the inner wall of the cooling circulation pipe 11 is fitted and connected with the outer wall of the motor body 9. The cooling circulation pipe 11 is designed to surround and fit the outside of the motor body 9, so that the cooling water in the cooling water tank 3 is transported through the motor body 9 through the cooling circulation pipe 11 to absorb the heat emitted by the motor.

[0023] As the second embodiment of the utility model: the staff first connects the circulating water pump 12 and the fan 14 to the external power supply and the external controller through wires, and uses the fan 14 to absorb the external wind to cool the running motor body 9. The design of multiple sets of ventilation holes 10 increases the air circulation inside the installation box 1, thereby increasing the heat dissipation efficiency of the motor body 9. When the filter 7 needs to be replaced, press the limiting movable plate 6 to allow the limiting movable plate 6 to enter the movable hole. At this time, the limiting movable plate 6 no longer limits the position of the fixed frame 15, and the fixed frame 15 can be pulled out. The cooling water inside the cooling water tank 3 is circulated and extracted by the circulating water pump 12. Because the cooling circulation pipe 11 surrounds and fits the outside of the motor body 9, the cooling water in the cooling water tank 3 is transported through the cooling circulation pipe 11 through the motor body 9, and the heat emitted by the motor is absorbed, further increasing the heat dissipation efficiency of the motor body 9.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
