Under this trend, the requirements for motors in equipment in various industries are also getting higher and higher. However, the temperature rise problem generated by the motor during long-term operation restricts the efficient operation of the motor, and the temperature rise problem will also reduce the service life of the motor.

[0003] There are several problems with existing motor liquid cooling mechanisms: 1. High-speed flow of coolant may have a large impact on pipes, components, etc., causing vibration and increasing the risk of wear and damage; 2. High flow of coolant may cause unstable system pressure and affect the normal operation of the equipment; 3. The coolant will carry some impurities during the process of circulating and absorbing heat inside the motor, and the accumulation of impurities will cause blockage in the pipes.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: comprising a motor 1, one end of the motor 1 is fixedly connected to a liquid inlet mechanism 2, one end of the motor 1 away from the liquid inlet mechanism 2 is fixedly connected to a liquid outlet pipe 3, and a circulation cavity 4 is provided inside the motor 1. By injecting the coolant from the liquid inlet mechanism 2, the coolant will then enter the inside of the motor 1, and then the coolant will circulate in the closed circulation cavity 4, and when the coolant flows through the heating part of the motor 1, it will absorb the heat generated by the motor 1 when it is running, and more precisely, it plays a role in timely absorbing the heat generated by the internal stator.

[0022] The cooling liquid after absorbing the heat will then be discharged from the liquid outlet pipe 3 and enter the external heat exchanger, so that the cooling liquid exchanges heat with the external environment, dissipates the heat, and cools the cooling liquid.

[0023] The cooled coolant will circulate into the motor 1 again to continue absorbing heat, and this cycle will be repeated to keep the motor 1 and the internal stator running within a suitable temperature range.

[0024] The liquid inlet mechanism 2 includes a liquid inlet component 21, the top of which is fixedly connected to an automatic exhaust valve 23, an end of the liquid inlet component 21 close to the automatic exhaust valve 23 is fixedly connected to a hollow nut 24, an end of the hollow nut 24 away from the liquid inlet component 21 is fixedly connected to an external pipe 25, a filter screen 22 is arranged inside the external pipe 25, and finally the coolant will enter the motor 1 through the hollow nut 24 and the external pipe 25 in turn, wherein the filter screen 22 plays a role in filtering impurities in the coolant, and the automatic exhaust valve 23 plays a role in automatically discharging air mixed in the coolant.

When the coolant enters the interior of the shell 211, the coolant with too fast flow rate and too large flow rate will impact on the impact outer plate 216, and the impacted impact outer plate 216 will carry the blocking slide plate 2 15, and moves inward along the inner rail 213, and at the same time, the spring 214 fixed on one end of the blocking slide 215 will be stretched, and the spring 214 fixed on the other end will be compressed, and then the opening originally blocked by the blocking slide 215 will be opened, wherein the opening is the only way to connect the layered shell 212 and the outer shell 211, so part of the coolant will enter the space formed by the layered shell 212 and the outer shell 211 through the opening for transportation, thereby playing a role in diverting and transporting high-flow and high-speed coolant, and elastic webs 217 are symmetrically arranged at both ends of the blocking slide 215, wherein the elastic webs 217 symmetrically arranged on both ends of the blocking slide 215 are elastic, and it prevents the coolant from entering the inner rail 213 and contaminating the spring 214, and the end of the elastic web 217 away from the blocking slide 215 is fixedly connected to the inner side of the inner rail 213.
