[0021] The small circulation device composed of the water pump 3, the cooling component 4, the radiator 5, the pipe 1 7, the pipe 4 10 and the pipe 5 11 is beneficial to improving the circulation efficiency of the coolant. The action of the cooling component 4 is used to realize the large and small circulation of the coolant, realize the basic constant temperature of the coolant, and at the same time, it can also ensure that the device will not damage the pipeline due to large temperature differences. It is equivalent to always controlling the part of the coolant close to the gearbox main body 1 at a suitable temperature, avoiding the increase of the pressure drop in the coolant circulation loop.

[0022] Among them, the pipe 6 12 is located at the upper right side of the cooling circulation device 2, and the pipe 7 13 is located at the lower right side of the cooling circulation device 2.

[0023] Ensure that the coolant inside the cooling circulation device 2 can circulate stably in the device, is not easy to have backflow, and can improve the circulation effect by accelerating the coolant through gravity.

[0024] Among them, a temperature sensor is installed at one end of the interior of the cooling circulation device 2 close to the gearbox body 1, and the interior of the cooling circulation device 2 is a cavity.

[0025] By sensing the temperature to adjust the internal circulation speed of the cooling circulation device 2, the large-area cavity can store more coolant, which is beneficial to ensuring the cooling of the gearbox body 1.

[0032] The working principle and usage process of the present utility model:

[0033] Start the gearbox body 1, the gearbox body 1 starts to work, and continuously generates heat during the working process. At this time, start the device, the coolant inside the liquid tank 6 enters the water pump 3 through the pipe three 9, and then the coolant reaches the cooling component 4 through the pipe one 7. During this process, the heat generated by the work of the gearbox body 1 is absorbed to cool the gearbox body 1. The cooling component 4 has a certain heat dissipation property. During the process of the coolant starting to cool down inside the cooling component 4, it will reach the radiator 5 through the pipe five 11. The coolant inside the radiator 5 will return to the liquid tank 6 through the pipe two 8 to complete the cooling completely. If the temperature of the gearbox body 1 is too high, the cooling circulation device 2 will be started. The coolant inside the cooling circulation device 2 flows into the cooling component 4 through the pipe seven 13 to join the coolant circulation between the cooling component 4 and the liquid tank 6, and then flows back to the inside of the cooling circulation device 2 through the pipe six 12 for cooling. After the coolant is consumed to a certain extent, it is replenished through the water inlet 15.
