[0024] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below. In the following description, a lot of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from the description, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0026] As shown in Figs. 1 to 4 The utility model discloses an electric machine equipment cooling structure including main casing 10, rotor assembly 20 and stator assembly 30, stator assembly 30 is fixed in main casing 10, rotor assembly 20 is set through stator assembly 30, rotor assembly 20 includes the shaft 21, and the shaft 21 is fixed in the both ends of main casing 10 through bearing seat 22, and the shaft 21 one end protrudes out of main casing 10 and is arranged, is used to be connected with the external equipment to be driven and is driven to drive the external equipment to be driven to run.

[0027] When the generator is running, it will continue to heat, and its heat source mainly has copper loss (wire resistance heating), iron loss (eddy current heating) and mechanical friction heating, which further causes the stator assembly 30 to heat, and the stator assembly 30 is placed in the main casing 10, and the heat of the stator assembly 30 will be conducted to the main casing 10, in order to improve the heat dissipation effect of the utility model, the following structure is used to solve the problem.

[0028] The outer side wall of the main casing 10 is provided with a water cooling groove 11, and the main casing 10 is provided with a baffle 12 on one side of the water cooling groove 11. The cross section of the baffle 12 is circular in structure, and the baffle 12 is fixedly surrounded on the outer side wall of the main casing 10, so as to close the water cooling groove 11 in cooperation with the outer side wall of the main casing 10. The water cooling groove 11 is used for circulating cooling water, and the baffle 12 is provided with an inlet pipe 13 and an outlet pipe 14 at both ends respectively. The cooling water enters the water cooling groove 11 from the inlet pipe 13, and then flows out of the water cooling groove 11 through the outlet pipe 14, so as to take away the heat on the main casing 10, thereby realizing the heat dissipation effect of the electric machine equipment cooling structure of the utility model.

[0029] In one embodiment, the baffle 12 is fixed on the outer side wall of the main casing 10 by welding, which effectively increases the stability of the connection between the baffle 12 and the main casing 10.

[0030] In one embodiment, the water cooling groove 11 is opened on the outer wall of the main shell 10 by milling. Compared with the method of winding the cooling water pipe on the outer wall of the main shell 10, the structural redundancy is reduced and the efficiency of heat conduction is increased. In addition, compared with the method of adding heat dissipation fins on the outer wall of the main shell 10, the efficiency of heat conduction is increased and the manufacturing cost is effectively reduced.

[0031] Furthermore, a spacer 15 is protruded from the outer wall of the main shell 10 in the water cooling groove 11. The spacer 15 is set in the water cooling groove 11 by milling. The spacer 15 is spirally wrapped around the outer wall of the main shell 10, thereby dividing the water cooling groove 11 into a spiral cooling channel. The cooling water flows into the cooling channel through the liquid inlet pipe 13 and then flows out of the cooling channel through the liquid outlet pipe 14, thereby taking away the heat on the main shell 10, thereby achieving the heat dissipation effect of the cooling structure of the motor equipment of the utility model.

[0032] In the actual operation of the motor, it is necessary to ensure that the motor responds quickly and meet the instantaneous heat dissipation requirements of the motor without damaging the rotor assembly of the motor equipment. Therefore, the moment of inertia of the rotor assembly should not be too large, and the mass and diameter of the rotor assembly need to be reduced as much as possible. The present invention adopts the following structure to solve this problem.

[0033] In one embodiment, the rotor assembly also includes a magnet 23, and a plurality of U-shaped receiving grooves 211 are spaced apart in the middle of the rotating shaft 21. The magnet 23 is clamped in the receiving groove 211. The magnet 23 is placed by opening the receiving groove 211 on the outer wall of the middle part of the rotating shaft 21. Compared with the iron core punching design, the mass of the rotor assembly is effectively reduced to the diameter, thereby reducing the rotational inertia of the rotor assembly to meet the instantaneous heat dissipation requirements of the motor without damaging the rotor assembly of the motor equipment.

[0034] Furthermore, the magnet 23 is adhered to the receiving groove 211 by a curing agent, which further improves the stability of the magnet 23 placed in the receiving groove 211 and avoids the problem of the magnet 23 being separated from the receiving groove 211 when the shaft 21 rotates, thereby increasing the service life of the rotor assembly; in this embodiment, the curing agent itself does not involve the inventive point of the present utility model, and can be manufactured using existing technology or obtained through purchase, and there is no need to elaborate on it here.

[0035] Furthermore, the cross-sectional opening width of the accommodating groove 211 gradually decreases from the inside to the outside, so that the magnet 23 can be confined in the accommodating groove 211, avoiding the problem of the magnet 23 being separated from the accommodating groove 211 when the shaft 21 rotates, thereby improving the service life of the rotor assembly.

[0036] Further, the rotor assembly further comprises a shielding layer 24 sleeved on the outer side of the rotating shaft 21 and covering the magnetic steel 23 in the accommodating groove 211, so as to avoid the problem that the magnetic steel 23 is separated from the accommodating groove 211 when the rotating shaft 21 rotates, thereby improving the service life of the rotor assembly; in the embodiment, the shielding layer 24 is a carbon fiber structure.

[0037] In one embodiment, in order to further improve the cooling effect of the motor device, the following structure can be used to solve the problem.

[0038] The front and rear ends of the main shell 10 are respectively provided with a fan 40, the fan 40 enters the main shell 10 through a pipeline 50, and an air outlet 16 is formed in the lower part of the main shell 10; the fan 40 sends external air into the main shell 10, and the heat generated in the internal motor device is discharged to the outside of the main shell 10, thereby improving the heat dissipation effect of the utility model.

[0039] Further, in order to avoid external dust and impurities from entering the motor, a filter plate can be arranged at the pipeline 50 and the air outlet 16, thereby improving the service life of the motor device.

[0040] When the motor device cooling structure of the utility model is in operation, the rotor assembly and the stator assembly 30 generate a large amount of heat due to the continuous rotation of the rotor assembly; the heat generated by the motor device is dissipated into the main shell 10, and the cooling water is sent into and out of the cooling channel arranged on the outer side wall of the main shell 10, thereby taking away the heat in the main shell 10, and the heat dissipation effect of the motor device cooling structure of the utility model is achieved; further, the fan 40 arranged outside the main shell 10 sends external air into the main shell 10 through the pipeline 50, thereby continuously taking away the heat in the main shell 10 to the outside of the main shell 10, achieving the heat dissipation operation of the motor device, and improving the service life of the motor device.

[0041] In summary, the motor device cooling structure of the utility model comprises a water cooling groove 11 arranged on the outer side wall of the main shell 10, and the heat on the main shell 10 is taken away by the cooling water flowing in the water cooling groove 11, thereby achieving the heat dissipation operation of the motor device and improving the service life of the motor device.
