Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically a motor frame structure that facilitates heat dissipation. Background Technology

[0002] During operation, electric motors generate a significant amount of heat due to electromagnetic losses and mechanical friction. Especially under prolonged high loads or high speeds, the internal temperature of the motor rises rapidly. If heat is not dissipated in time, this will lead to decreased motor efficiency and may cause aging of insulation materials, deformation of components, or even damage, thus affecting the motor's lifespan and operational safety. Therefore, a good heat dissipation design is crucial for ensuring stable motor operation and extending its lifespan.

[0003] Currently, most motor frame structures rely on the heat dissipation fins on the outer circle of the frame and its surrounding area for heat dissipation. However, due to insufficient air circulation and limited heat dissipation area, it is difficult to effectively dissipate internal heat, resulting in poor heat dissipation. Especially when heat accumulates inside the motor cavity, relying solely on the heat dissipation fins on the outside of the frame is not conducive to maintaining the continuous and stable operation of the motor in high-temperature environments. Utility Model Content

[0004] The purpose of this utility model is to provide a heat-dissipating motor base structure to solve at least one aspect of the problems and defects mentioned in the background art.

[0005] A heat-dissipating motor base structure is provided, including a junction box base, which is disposed on the base housing. Several ventilation slot assemblies are arranged around the upper part of the base housing, and several ventilation pipe assemblies are arranged between two adjacent ventilation slot assemblies. Several heat dissipation fins are also provided on the upper part of the base housing.

[0006] Furthermore, the ventilation slot assembly includes a connecting slot plate, which is fixedly connected to the base housing. A heat dissipation slot plate is fixedly connected to the upper part of the connecting slot plate. After air enters through the opening of the ventilation slot assembly, it flows between the heat dissipation slot plates due to the guiding effect of the heat dissipation slot plates, carrying away the heat of the motor base housing. By increasing the contact area and flow path between the air and the heat dissipation surface, it is ensured that the heat can be effectively and quickly dissipated from the base housing.

[0007] Furthermore, the upper part of the base housing is also provided with several flow guide slots, which are connected to the heat dissipation slots. The flow guide slots guide the air inside the base housing into the heat dissipation slots and flow between the heat dissipation slots. By increasing the contact area and flow path between the air and the heat dissipation surface, the heat can be effectively and quickly dissipated from the base housing.

[0008] Furthermore, the ventilation duct assembly includes a support plate, on which ventilation duct bodies are provided. The ventilation duct bodies are arranged on the support plate to form multiple longitudinal ventilation channels. Their main function is to guide air from the outside into the machine base housing and form a good ventilation path. Through these channels, cold air can enter the inner cavity of the machine base housing and take away heat, thereby accelerating the exhaust of hot air inside.

[0009] Furthermore, both sides of the ventilation duct are provided with arc transition sections, and the interior of the ventilation duct is a hollow structure. The surface of the arc transition section is smooth, which increases the contact area between the air and the ventilation duct. As the air flows through these arc surfaces, it increases the heat dissipation effect of the entire heat dissipation system.

[0010] Furthermore, both sides of the ventilation duct are provided with arc transition sections. The interior of the ventilation duct is a hollow structure, and the ventilation holes are evenly distributed in the circumferential direction of the base housing. The ventilation holes are connected to the ventilation duct, so that external air can enter the internal space of the base housing more evenly, promoting air exchange between the inside and outside of the motor and forming effective convection, thereby improving the overall heat dissipation efficiency of the motor.

[0011] Furthermore, the base housing is provided with a number of ventilation holes along the circumferential direction. These ventilation holes are connected to the ventilation duct. The presence of the ventilation holes provides a direct outlet for hot air, avoiding the accumulation of heat. At the same time, the hot air is discharged to the outside of the base housing under the guidance of the ventilation duct, further accelerating the heat dissipation speed.

[0012] Furthermore, lifting rings are provided on both sides of the upper part of the base housing. The lifting rings provide a structure specifically for hoisting, making the motor safer and more convenient during handling, installation and maintenance.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The ventilation slot assembly, ventilation pipe assembly, and heat dissipation fins provided by this utility model together form a highly efficient heat dissipation system. The ventilation slot assembly and ventilation pipe assembly accelerate the airflow inside the housing, while the heat dissipation fins increase the heat dissipation area, thereby allowing the heat inside the motor cavity to be dissipated to the outside more quickly. The synergistic effect of this system structure can effectively prevent the internal temperature of the motor from becoming too high, extend the service life of the motor, improve its working stability, enhance the airflow inside the housing cavity, and increase the air contact area, thus helping to reduce the heat inside the motor cavity and achieving good heat dissipation effect.

Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this application and are not intended to limit the subject matter of the claims.

[0023] Please see Figure 1-3 As shown in the embodiment of this utility model, a heat-dissipating motor base structure includes a junction box base 1, which is mounted on a base housing 2. Several ventilation slot assemblies 3 are arranged around the upper perimeter of the base housing 2, and several ventilation pipe assemblies 4 are arranged between adjacent ventilation slot assemblies 3. Several heat dissipation fins 5 are also provided on the upper part of the base housing 2. The ventilation slot assemblies 3 form an open air channel, allowing air to flow in from the outside and circulate around the base housing 2, carrying away heat. This air convection process can accelerate the cooling of the outer surface of the base housing 2.

[0024] The ventilation duct assembly 4 serves as an auxiliary channel, allowing air to enter the internal space of the base housing 2, ensuring smoother internal and external air circulation, thereby further removing heat from the motor.

[0025] The heat dissipation fins 5 effectively increase the heat dissipation area. The arrangement of the heat dissipation fins 5 allows more air to come into contact with the chassis housing 2, thereby enhancing the heat dissipation effect. The structure of the heat dissipation fins 5 accelerates the heat transfer process, transferring heat from the surface of the chassis housing 2 to the air and accelerating cooling.

[0026] The ventilation slot assembly 3, ventilation pipe assembly 4, and heat dissipation fins 5 together form a highly efficient heat dissipation system. The ventilation slot assembly 3 and ventilation pipe assembly 4 accelerate airflow, and the heat dissipation fins 5 increase the heat dissipation area, so that the heat inside the motor cavity can be dissipated to the outside more quickly. The synergistic effect of this system structure can effectively prevent the internal temperature of the motor from becoming too high, extend the service life of the motor, and improve its working stability. Through the structure of the ventilation slot assembly 3, ventilation pipe assembly 4, and heat dissipation fins 5, the airflow inside the base housing 2 is enhanced and the air contact area is increased, which helps to reduce the heat inside the motor cavity and achieves good heat dissipation effect.

[0027] In one embodiment, see Figure 1 and Figure 2The ventilation slot assembly 3 includes a connecting slot plate 31, which is fixedly connected to the base housing 2. A heat dissipation slot plate 32 is fixedly connected to the upper part of the connecting slot plate 31. The connecting slot plate 31 provides support and stability for the entire ventilation slot assembly 3, allowing the ventilation slot assembly 3 to fit better with the base housing 2. This facilitates the smooth entry of air from the outside of the base into the ventilation slot assembly 3, ensuring unobstructed airflow. The combination of the connecting slot plate 31 and the heat dissipation slot plate 32 forms a structure that promotes airflow and heat exchange. After air enters through the opening of the ventilation slot assembly 3, it flows between the heat dissipation slot plates 32 through the guiding effect of the heat dissipation slot plates 32, carrying away the heat from the motor base housing 2. By increasing the contact area and flow path between the air and the heat dissipation surface, heat can be effectively and quickly dissipated from the base housing 2.

[0028] In one embodiment, see Figure 1 and Figure 2 The upper part of the base housing 2 is also provided with several flow guide slots 21, which are connected to the heat dissipation plate 32. The flow guide slots 21 guide the air inside the base housing 2 into the heat dissipation plate 32, where it flows between the heat dissipation plates 32, further carrying away the heat of the motor base housing 2. By increasing the contact area and flow path between the air and the heat dissipation surface, the heat can be effectively and quickly dissipated from the base housing 2.

[0029] Specifically, please refer to Figure 1 and Figure 3 As shown, the ventilation duct assembly 4 includes a support plate 41, on which ventilation duct bodies 42 are provided. The ventilation duct bodies 42 are provided on the support plate 41, forming multiple longitudinal ventilation channels. Their main function is to guide air from the outside into the machine base housing 2 and form a good ventilation path. Through these channels, cold air can enter the inner cavity of the machine base housing 2 and carry away heat, thereby accelerating the discharge of hot air inside.

[0030] Further, please refer to Figure 3 As shown, both sides of the ventilation duct 42 are provided with arc-shaped transition portions 421. The surface of the arc-shaped transition portions 421 is smooth, increasing the contact area between the air and the ventilation duct 42. As the air flows through these arc-shaped surfaces, it increases the heat dissipation effect of the entire heat dissipation system, further reducing the motor temperature. The arc-shaped transition portions 421 allow the airflow to pass smoothly through the ventilation duct 42, avoiding the generation of eddies or turbulence at the edges, allowing the air to pass through the ventilation channel more smoothly, thereby improving the airflow efficiency.

[0031] Please see Figure 1 and Figure 3As shown, the base housing 2 is provided with a number of ventilation holes 22 along the circumferential direction. The ventilation holes 22 are connected to the ventilation pipe body 42. The ventilation holes 22 are evenly distributed in the circumferential direction of the base housing 2. The ventilation holes 22 are connected to the ventilation pipe body 42, so that the external air can enter the internal space of the base housing 2 more evenly, which promotes the air exchange between the inside and outside of the motor, forms effective convection, and thus improves the overall heat dissipation efficiency of the motor.

[0032] When the motor is running, the heat generated inside is quickly discharged through the ventilation hole 22 and the ventilation pipe 42. The presence of the ventilation hole 22 provides a direct outlet for hot air, avoiding the accumulation of heat. At the same time, the hot air is discharged to the outside of the base housing 2 under the guidance of the ventilation pipe 42, further accelerating the heat dissipation speed.

[0033] Specifically, lifting rings 6 are provided on both sides of the upper part of the base housing 2. The lifting rings 6 provide a structure specifically for hoisting, making the motor safer and more convenient during handling, installation and maintenance. Through the lifting rings 6, the motor can be securely connected to the hoisting equipment, avoiding equipment damage or accidents caused by improper handling.

[0034] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
