Abstract

This utility model discloses a water-cooled motor, including a cooling assembly comprising a housing, a stator core, a spiral groove, a water inlet, and a water outlet. The stator core has a spiral groove on its outer ring, and the housing is movably connected to the outer side of the stator core. The water inlet and outlet are formed through the housing, with the water inlet connected to the first end of the spiral groove and the water outlet connected to the last end of the spiral groove. A disturbance assembly includes a spiral rod and a propeller. The spiral rod is fixedly installed in the middle of the spiral groove, and the propeller is movably connected to the top of the spiral rod. This utility model enables the propeller to rotate around a cylindrical shaft, thereby agitating the water flow to generate radial vortices.

Description

Technical Field

[0001] This utility model relates to the field of motor cooling technology, specifically to a motor with a water-cooled structure. Background Technology

[0002] Motors generate heat when they are working, and water cooling structures are usually installed to cool them. The principle is to efficiently remove the heat generated by the motor by circulating a liquid cooling medium (such as water or a specific coolant), thereby controlling the temperature and ensuring performance and lifespan.

[0003] Existing water-cooling structures for motors typically employ a single spiral groove structure, resulting in a limited water flow pattern and poor actual heat exchange and cooling efficiency. There is still considerable room for improvement, therefore a new structure is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a motor with a water-cooled structure to solve the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a motor with a water-cooled structure, including:

[0006] A cooling assembly includes a housing, a stator core, a spiral groove, a water inlet, and a water outlet. The stator core has a spiral groove on its outer ring.

The water inlet is connected to the first end of the spiral groove, and the water outlet is connected to the last end of the spiral groove.

[0007] A disturbance component, comprising a helical rod and a propeller, wherein the helical rod is fixedly installed in the middle of the helical groove and the propeller is movably connected to the top of the helical rod.

[0008] Furthermore, there are a total of five propellers, which are arranged at equal intervals.

[0009] Furthermore, the disturbance component also includes a C-shaped frame, a receiving groove, and a cylindrical shaft. The C-shaped frame is fixedly connected to the helical rod, the receiving groove is opened through the C-shaped frame, the cylindrical shaft is movably connected in the receiving groove, and a propeller is fixedly connected to one end of the cylindrical shaft.

[0010] Furthermore, the disturbance component also includes a limiting circular plate, and the other end of the cylindrical shaft is fixedly connected to the limiting circular plate, which is located between the C-shaped frame and the spiral rod.

[0011] Furthermore, it also includes a filter assembly, which includes a cylindrical cylinder and a filter screen. The cylindrical cylinder is fixedly connected to the top of the water inlet, and the filter screen is movably installed in the cylindrical cylinder.

[0012] Furthermore, the filter assembly also includes a slot, an L-shaped lever, and a receiving plate.

[0013] Furthermore, the filter assembly also includes a wing screw, which is movably connected to the L-shaped lever and the threaded hole on the receiving plate.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the propeller, under the impact of water flow and with the cooperation of the receiving groove, can rotate around the cylindrical shaft, thereby stirring the water flow to generate radial vortices, which disrupts the low-velocity laminar boundary layer formed by the water flow on the wall, thus greatly improving the heat exchange efficiency and thus significantly improving the cooling effect.

[0016] Based on the above-mentioned beneficial effects, by installing a filter screen plate at the cylindrical part above the water inlet, hard particles (such as iron filings) in the water flow entering the spiral channel can be intercepted and filtered, preventing them from colliding with the propeller, thereby preventing damage to the propeller and extending the service life of the propeller; and by pulling up the L-shaped lever, the filter screen plate can be quickly removed, making it easy to disassemble and deal with it in time when it becomes clogged.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is a motor with a water-cooled structure, comprising:

[0029] The cooling assembly includes a housing 101, a stator core 102, a spiral groove 103, a water inlet 104, and a water outlet 105. The stator core 102 has a spiral groove 103 on its outer ring. The outer side of the stator core 102 is movably connected to the housing 101. The housing 101 has a water inlet 104 and a water outlet 105 through it. The water inlet 104 is connected to the first end of the spiral groove 103, and the water outlet 105 is connected to the last end of the spiral groove 103.

[0030] The disturbance component includes a helical rod 201 and a propeller 202. The helical rod 201 is fixedly installed in the middle of the helical groove 103, and the propeller 202 is movably connected to the top of the helical rod 201. There are a total of five propellers 202, which are arranged at equal intervals.

[0031] The inlet end 104 and outlet end 105 ensure the entry and exit of cooling water at the spiral groove 103. The spiral rod 201 can further disperse the water flow and ensure the movable installation of the propeller 202. The number of propellers 202 can ensure that vortices can be generated in each area of ​​the water flow.

[0032] The disturbance assembly also includes a C-shaped frame 203, a receiving groove 204, and a cylindrical shaft 205. The C-shaped frame 203 is fixedly connected to the helical rod 201. The receiving groove 204 is opened through the C-shaped frame 203. The cylindrical shaft 205 is movably connected in the receiving groove 204. One end of the cylindrical shaft 205 is fixedly connected to the propeller 202. The disturbance assembly also includes a limiting circular plate 206. The other end of the cylindrical shaft 205 is fixedly connected to the limiting circular plate 206. The limiting circular plate 206 is located between the C-shaped frame 203 and the helical rod 201.

[0033] The C-shaped frame 203 provides a guarantee for the opening of the receiving groove 204. The receiving groove 204 provides a guarantee for the cylindrical shaft 205 to drive the propeller 202 to rotate. The limiting circular plate 206 is used to limit the cylindrical shaft 205 and prevent it from falling off the C-shaped frame 203.

[0034] Working principle: First, water inlet pipe and water outlet pipe are installed at the water inlet 104 and water outlet 105 respectively. Then, cooling water is introduced into the water inlet 104. The cooling water flows along the spiral groove 103 and is divided by the spiral rod 201. When the cooling water moves to the position of the propeller 202, the water flow impacts the propeller 202. At this time, the cylindrical shaft 205 rotates at the receiving groove 204, realizing the rotation of the propeller 202. At this time, a vortex is formed at the water flow end, which destroys the water flow boundary layer and improves the heat exchange effect.

[0035] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0036] The filter assembly includes a cylindrical cylinder 301 and a filter screen 302. The top of the water inlet 104 is fixedly connected to the cylindrical cylinder 301, and the filter screen 302 is movably installed in the cylindrical cylinder 301.

[0037] The circular cylinder 301 provides a guarantee for the installation of the filter screen 302, which is used to intercept hard particles in the filtered water flow.

[0038] The filter assembly also includes a slot 303, an L-shaped lever 304, and a receiving plate 305. The inner ring of the cylindrical cylinder 301 has a slot 303. The side of the filter screen 302 is fixedly connected to the L-shaped lever 304. The slot 303 movably engages with the L-shaped lever 304. The side of the cylindrical cylinder 301 is fixedly connected to the receiving plate 305. The top of the receiving plate 305 is movably connected to the L-shaped lever 304. The filter assembly also includes a wing screw 306. The wing screw 306 movably connects the L-shaped lever 304 and the threaded hole on the receiving plate 305.

[0039] The slot 303 ensures the smooth engagement of the L-shaped lever 304. The L-shaped lever 304 facilitates the user's removal and insertion of the filter screen 302 from the cylindrical tube 301. The receiving plate 305 and the wing screw 306 ensure the secure installation of the L-shaped lever 304 and the filter screen 302.

[0040] Working principle: Before use, engage the L-shaped clamp 304 with the clamping slot 303. At this time, the filter screen 302 is installed in the cylindrical tube 301 to intercept hard particles in the water flow entering the inlet 104. When the filter screen 302 becomes clogged, unscrew the wing screw 306 from the threaded groove in the L-shaped clamp 304 and the receiving plate 305, and then pull the L-shaped clamp 304 upward to remove the filter screen 302. After cleaning, repeat the above process in reverse to install the filter screen 302.
