Description

Technical Field

[0001] This utility model relates to the field of motor housing technology, and in particular to a novel water-cooled heat dissipation structure for motor housing. Background Technology

[0002] The motor housing is a crucial component of an electric motor, primarily functioning to protect internal components, dissipate heat, and secure the motor. Motors generate heat during operation; if this heat is not dissipated promptly, it can overheat and damage the motor. Motor housings are typically designed with heat dissipation in mind, incorporating features such as heat sinks and ventilation openings to ensure the motor maintains a suitable temperature during operation.

[0003] To enhance heat dissipation, existing motor housings typically incorporate water-cooling chambers. Cooling water flows through these chambers to dissipate heat from the motor housing, thus achieving effective cooling. However, the existing water-cooling chamber structures are relatively simple, with both uncooled and cooled water mixing inside, making it difficult to maximize the cooling effect and hindering long-term use and widespread adoption. Therefore, those skilled in the art have proposed a novel water-cooled heat dissipation structure for motor housings to address the problems described in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel water-cooled heat dissipation structure for motor housings. This solves the problem mentioned in the background art that the water-cooling cavity structure on the motor housing is relatively simple, with both uncooled and cooled water mixed inside the water-cooling cavity, making it difficult to maximize the cooling effect and thus hindering long-term use and promotion.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel water-cooled heat dissipation structure for a motor housing, comprising a housing, wherein an annular cooling cavity is provided inside the housing, and first fins arranged in annular shape at equal intervals are arranged inside the annular cooling cavity. Circular holes arranged in a circumferential array and penetrating through the outer walls of several first fins are provided. A water inlet pipe communicating with the annular cooling cavity is fixed to the left end of the top of the outer peripheral sidewall of the housing, and a water outlet pipe communicating with the annular cooling cavity is fixed to the right end of the bottom of the outer peripheral sidewall of the housing. Support plates are fixedly connected to both ends of the outer peripheral sidewall of the housing, and a base plate is fixedly fixed to the outer bottom surfaces of the two support plates. An air-cooling component is provided inside the base plate.

[0006] As a further technical solution of this utility model, the air-cooling component includes a circular cavity opened inside the base plate. A rotating shaft is rotatably installed on the inner bottom surface of the circular cavity. Impellers arranged in a circular array are fixedly installed on the outer peripheral sidewall of the rotating shaft. One end of the rotating shaft extends rotatably to the outer top surface of the base plate, and fan blades arranged in a circular array are fixedly installed on the outer peripheral sidewall. A water guiding channel communicating with the circular cavity is opened inside the base plate, and one end of the water outlet pipe is connected to the water guiding channel.

[0007] As a further technical solution of this utility model, a square cover is fixedly installed on the outer top surface of the base plate and outside the fan blade. A filter screen is fixed on the outer top surface of the square cover by bolts, and a drain pipe that communicates with the circular cavity is fixedly installed on the outer bottom surface of the base plate.

[0008] As a further technical solution of this utility model, a spiral-shaped second fin is fixedly installed on the outer peripheral side wall of the housing.

[0009] As a further technical solution of this utility model, annular sealing grooves are provided on the outer walls of both the left and right sides of the housing, and internal thread grooves arranged in a circular array are provided on the inner side walls of the two annular sealing grooves.

[0010] As a further technical solution of this utility model, mounting plates are fixed on the outer walls of the front and rear sides of the base plate, and through screw holes are opened on the outer top surfaces of the two mounting plates.

[0011] This utility model provides a novel water-cooled heat dissipation structure for motor housing, which has the following advantages compared with the prior art:

[0012] 1. This design presents a novel water-cooled heat dissipation structure for motor housings. By setting the first fins and circular holes, several cooling channels are formed in the annular cooling cavity. Then, cooling water is introduced into the annular cooling cavity along the water inlet pipe and flows axially to the right, thereby extending the residence time of the cooling water in the annular cooling cavity and separating the uncooled cooling water from the cooled water, thereby improving the cooling effect.

[0013] 2. This design presents a novel water-cooled heat dissipation structure for motor housings. Through the set water guide channels and water outlet pipes, the cooled water after heat dissipation can be introduced into the circular cavity, and the cooling water impacts the impeller to generate power, thereby driving the rotating shaft to drive the fan blades to rotate in a circle, thus generating wind power to perform air cooling on the second fins, thereby improving the heat dissipation effect of the second fins on the annular cooling cavity, and thus improving the heat dissipation effect on the motor housing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides a novel water-cooled heat dissipation structure for a motor housing: it includes a housing 1, with support plates 106 fixedly connected to both ends of the outer periphery of the housing 1. A base plate 107 is fixed to the outer bottom surface of the two support plates 106. Mounting plates 4 are fixed to the outer walls of the front and rear sides of the base plate 107. A through-hole screw hole 401 is opened on the outer top surface of the two mounting plates 4. The bolts in the screw holes 401 are turned to fix the base plate 107 in a designated area to ensure the stability of the motor housing 1 in subsequent use. Annular sealing grooves 3 are opened on the outer walls of the left and right sides of the housing 1. The inner side walls of the two annular sealing grooves 3 are opened with internal thread grooves 301 arranged in a circumferential array. After the motor is placed inside the housing 1, the sealing covers at both ends of the motor are installed using the annular sealing grooves 3 and internal thread grooves 301 at both ends of the housing. The motor can be used after assembly.

[0025] The casing 1 has an annular cooling cavity 101 inside. The annular cooling cavity 101 has first fins 102 arranged in a ring at equal intervals inside. The outer walls of several first fins 102 have circular holes 103 arranged in a circumferential array and penetrating through them. The left end of the top of the outer side wall of the casing 1 is fixed with a water inlet pipe 104 that communicates with the annular cooling cavity 101. The right end of the bottom of the outer side wall of the casing 1 is fixed with a water outlet pipe 105 that communicates with the annular cooling cavity 101. The water inlet pipe 104 is connected to the external cooling water supply pipe, and then the cooling water is delivered into the annular cooling cavity 101 and flows axially along the circular holes 103 toward the right side of the annular cooling cavity 101. This prolongs the residence time of the cooling water in the annular cooling cavity 101 and separates the uncooled cooling water from the cooled water after it has been cooled, thereby improving the cooling effect. Afterward, the cooling water is discharged along the water outlet pipe 105.

[0026] An air-cooling assembly 2 is disposed inside the base plate 107. The air-cooling assembly 2 includes a circular cavity 201 formed inside the base plate 107. A rotating shaft 202 is rotatably mounted on the inner bottom surface of the circular cavity 201. Impellers 203 arranged in a circular array are fixedly mounted on the outer peripheral sidewall of the rotating shaft 202. One end of the rotating shaft 202 extends rotatably to the outer top surface of the base plate 107, and fan blades 204 arranged in a circular array are fixedly mounted on the outer peripheral sidewall. The interior of the device has a water guiding channel 205 that communicates with the circular cavity 201. One end of the water outlet pipe 105 is connected to the water guiding channel 205. A square cover 206 is fixedly installed on the outer top surface of the base plate 107 and outside the fan blade 204. A filter screen 207 is fixed to the outer top surface of the square cover 206 by bolts (the filter screen 207 is used to prevent impurities from falling onto the fan blade 204 and causing damage). A device that communicates with the circular cavity 201 is fixedly installed on the outer bottom surface of the base plate 107. A through-hole drain pipe 208 is provided, and a spiral second fin 209 is fixedly installed on the outer peripheral side wall of the casing 1. First, the external cooling water recovery pipe is connected to the drain pipe 208. Then, the cooled water after heat dissipation is sent into the water guide channel 205 along the outlet pipe 105, enters the circular cavity 201, and is discharged and recovered through the drain pipe 208. When the cooling water flows in the circular cavity 201, the outlet pipe 105 is pressurized by the pressurization device installed on the base plate 107 (the pressurization device is existing technology, and its working principle and structure will not be specifically described or shown in the text). This allows the cooling water to have sufficient water pressure to impact the impeller 203 to generate power, which in turn drives the rotating shaft 202 to drive the fan blade 204 to rotate in a circle and generate wind to cool the second fin 209. This improves the heat dissipation effect of the second fin 209 on the annular cooling cavity 101, thereby improving the heat dissipation effect on the motor casing 1.

[0027] The working principle of this utility model is as follows: When in use, cooling water is first transported to the annular cooling chamber 101 along the inlet pipe 104, and flows axially to the right side of the annular cooling chamber 101 along the circular hole 103, and is discharged along the outlet pipe 105. This prolongs the residence time of the cooling water in the annular cooling chamber 101 and allows the unheated cooling water and the cooled water after heat dissipation to separate from each other, thereby improving the cooling effect.

[0028] Meanwhile, the cooled water after heat dissipation is sent into the water guide channel 205 along the outlet pipe 105, enters the circular cavity 201 and is discharged and recycled through the drain pipe 208. This allows the cooled water to impact the impeller 203 to generate power, which in turn drives the rotating shaft 202 to drive the fan blade 204 to rotate in a circle and generate wind to perform air cooling on the second fin 209. This improves the heat dissipation effect of the second fin 209 on the annular cooling cavity 101, thereby improving the heat dissipation effect on the motor housing 1.

The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
