Description

Technical Field

[0001] This utility model relates to the field of motor base technology, and specifically to a motor base structure. Background Technology

[0002] When an electric motor is working, not all of the input electrical energy is converted into output mechanical energy. Internal losses occur, including stator copper losses, rotor copper losses, core losses, air wear losses, and stray losses. These losses are ultimately converted into heat, causing the internal temperature of the motor to rise and eventually burn out. Therefore, internal cooling of the motor is crucial. Current cooling methods mainly include air-to-air cooling, air-to-water cooling, and external cooling fins. Air-to-air and air-to-water cooling both require a dedicated external cooler. Hot air inside the motor circulates into the cooler, where it is cooled by water or external cold air before being circulated back into the motor. This method is inefficient and requires a large space. External cooling involves welding heat dissipation fins to the outside of the motor frame, increasing the contact area between the frame and the air, dissipating heat into the surrounding air. This method is suitable for small and medium-sized motors and is effective when the heat generation is small, but becomes inadequate when the heat is large. Utility Model Content

[0003] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0004] A motor base structure includes a motor housing, with base plates fixedly installed on both sides of the motor housing near the bottom. An outer cover is provided on the outside of the motor housing and fixed to the base plates. A water channel is formed between the motor housing and the outer cover. Multiple water channel ribs are fixed on the outer cover at the water channel location, and the water channel ribs abut against and support the motor housing. A water inlet and a water outlet are fixed at the rear top of the outer cover, and both the water inlet and the water outlet are connected to the inside of the outer cover.

[0005] Furthermore, a cable outlet is fixed at the top front side of the motor housing, and the outer casing is offset from the cable outlet. At least two support ribs are fixed on the base plates on both sides, and a grounding block is fixed on the base plate between the two support ribs. The support ribs are used to increase the fixing strength between the base plate and the motor housing, while the grounding block facilitates the grounding of the motor.

[0006] Furthermore, lifting rods are fixed to the top of the motor housing on both the left and right sides, and temperature sensors are installed on both the inlet and outlet. The lifting rods facilitate the hoisting of the motor, and the temperature sensors can measure the temperature of the inlet and outlet water, thereby understanding the heat dissipation situation based on the temperature data.

[0007] Furthermore, multiple evenly spaced fan shrouds are fixed to the outer side of the outer casing, and multiple equally spaced heat dissipation ribs are fixed to the outer casing inside the fan shrouds. Ventilation openings are provided on the front side of the motor housing corresponding to each fan shroud position. When the fan inherently mounted at the rear of the motor rotates, the fan typically blows air towards the rear of the motor, thus creating a negative pressure suction in front of the motor. This suction draws hot air from inside the motor housing through the fan shrouds, allowing the hot air to circulate through the ventilation openings and fan shrouds, and ultimately blown out towards the rear of the motor, thereby improving the heat dissipation effect on the motor.

[0008] Furthermore, a motor tail cover is installed on the rear side of the motor housing, and a motor fan is installed inside the motor tail cover. The rear part of the fan cover extends into the motor tail cover. The fan cover is located on the left and right sides of the outer housing near the top. Water covers are installed on the left and right sides of the outer housing near the bottom. The water covers have pre-set cavities that communicate with the inside of the outer housing. The rear part of the water covers extends into the motor tail cover. A partition is fixed inside the water cover at the rear of the motor housing, and multiple heat sinks are fixed inside the water cover behind the partition. This allows for heat absorption inside the motor tail cover, which, combined with the rotation of the motor fan, reduces the temperature inside the tail cover.

[0009] Furthermore, the water cover has openings corresponding to the positions between adjacent heat sinks, and the motor tail cover has air inlets corresponding to the opening positions. When the motor fan rotates, it simultaneously draws in external air through the air inlets. At this time, the water and heat sinks form a heat dissipation connection, which can cool the passing air and reduce the temperature of the air entering the motor tail cover, thereby ensuring the heat dissipation effect of the motor fan.

[0010] Furthermore, the multiple water channel ribs between the motor housing and the outer casing are arranged in a trapezoidal shape, with the upper end receding forward and the lower end advancing backward. The water inlet and outlet are located behind the upper water channel rib. This trapezoidal arrangement facilitates water flow through the multiple water channel ribs on the circumferential surface of the motor housing and prevents the upper water channel ribs from obstructing the lower water channel ribs.

[0011] Furthermore, a water outlet pipe is connected to the bottom of the outlet. The bottom opening of the water outlet pipe is located at the rear end of the lower water channel rib. The rear end of the lower water channel rib abuts against the water outlet pipe, and a gap is reserved between the front end of the water channel rib and the outer casing. The water outlet pipe sets the heights of the inlet and outlet off to prevent water from being drawn out as soon as it enters the water channel, allowing the water to absorb heat stably and reliably within the water channel.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides an outer cover for the motor housing and a water channel between the motor housing and the outer cover. Cooling water can be injected into the water channel to absorb heat from the motor housing, thereby reducing the motor temperature and achieving good heat dissipation.

[0014] 2. In this utility model, by setting a fan cover on the outside of the outer casing and using a ventilation port to communicate with the inside of the motor housing, when the motor fan rotates, it can draw in hot air from inside the motor and blow it out from the rear of the motor, thereby increasing the heat dissipation effect of the existing motor fan on the motor.

[0015] 3. In this utility model, by setting a water cover, cooling water can be used to cool the heat sink, and the heat sink can be used to absorb heat from the air entering the motor tail cover, so as to further improve the heat dissipation effect of the motor fan.

[0016] 4. In this utility model, by setting the water channel ribs in a ladder shape and using them in conjunction with the water outlet pipe, it can be ensured that the cooling water can flow on the surface of the motor housing, thereby achieving reliable and stable heat absorption and ensuring the water cooling effect.

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

[0028] This application provides a motor frame structure, mainly addressing the problems mentioned in the background art, and provides the following technical solution, which will be discussed in conjunction with... Figures 1-9 Please provide a detailed explanation:

[0029] Example 1, please refer to Figures 1-4 A motor base structure includes a motor housing 8, an outer cover 6 on the outside of the motor housing 8, a water channel 7 between the motor housing 8 and the outer cover 6, multiple water channel ribs 5 fixed on the outer cover 6 at the location of the water channel 7, the water channel ribs 5 abutting and supporting the motor housing 8, and base plates 10 fixedly installed on the bottom positions of both sides of the motor housing 8, the base plates 10 of the outer cover 6 are fixed, and at least two support ribs 9 are fixed on the base plates 10 on both sides, and a grounding block 14 is fixed on the base plate 10 between the two support ribs 9;

[0030] Lifting ribs 2 are fixed on the top of the motor housing 8 on both the left and right sides. A cable outlet 1 is fixed on the top front side of the motor housing 8. The outer cover 6 is offset from the cable outlet 1. A water inlet 11 and a water outlet 12 are fixed on the top rear side of the outer cover 6. Both the water inlet 11 and the water outlet 12 are connected to the inside of the outer cover 6. Temperature sensors 13 are installed on both the water inlet 11 and the water outlet 12.

[0031] During use, cooling water is introduced into the water channel 7 between the motor housing 8 and the outer casing 6 through the water inlet 11. The water enters the water channel 7 and comes into direct contact with the motor housing 8. When the heat inside the motor is transferred to the motor housing 8, it can be absorbed by the water. The water circulates in the water channel 7 and is then drawn out from the water outlet 12, forming a water-cooled heat dissipation for the motor. The heat dissipation effect is obvious, and the larger the coverage area of ​​the water channel 7 on the motor housing 8, the higher the heat dissipation effect.

[0032] Multiple evenly spaced fan covers 4 are fixed on the outer side of the outer casing 6. Multiple equally spaced heat dissipation ribs 3 are fixed on the outer casing 6 inside the fan cover 4. Ventilation openings 15 are provided on the front side of the motor housing 8 corresponding to each fan cover 4 position.

[0033] When the tail cover of the motor is connected to the rear end of the motor housing 8, due to the setting of the ventilation port 15, when the fan at the tail of the motor blows air to the rear of the motor, it will draw hot air from inside the motor housing 8 into the fan cover 4, and then through the heat dissipation fins 3, and then be blown out from the tail cover. When the airflow passes through the heat dissipation fins 3, it can transfer heat to the water in the water channel 7 for heat dissipation. Combined with the heat absorption of water directly in contact with the motor housing 8, a combination of water cooling and air cooling is formed.

[0034] Example 2, please refer to Figures 5-9 The difference between this embodiment and Embodiment 1 is that:

[0035] A motor tail cover 16 is installed on the rear side of the motor housing 8. A motor fan 17 is installed inside the motor tail cover 16. The rear part of the fan cover 4 extends into the motor tail cover 16. The fan cover 4 is located on the left and right sides of the outer housing 6 near the top. A water cover 18 is installed on the left and right sides of the outer housing 6 near the bottom. A cavity 19 is pre-set inside the water cover 18. The cavity 19 communicates with the inside of the outer housing 6. The rear part of the water cover 18 extends into the motor tail cover 16. A partition 20 is fixed inside the water cover 18 at the rear of the motor housing 8. Multiple heat sinks 21 are fixed inside the water cover 18 behind the partition 20. An opening 22 is opened on the water cover 18 between adjacent heat sinks 21. An air inlet 23 is opened on the motor tail cover 16 at the position corresponding to the opening 22.

[0036] Water entering through inlet 11 flows into water channel 7 and simultaneously enters water cover 18. Water cover 18 and partition 20 absorb heat and cool the area around heat sink 21. When motor fan 17 rotates, it can draw in airflow not only from fan cover 4 but also from air inlet 23. When airflow enters air inlet 23, it can be cooled to a certain extent by heat sink 21, so that airflow below ambient temperature is drawn in by motor fan 17. The lower temperature can improve the heat dissipation effect on the motor.

[0037] The rear ends of the multiple water channel ribs 5 between the motor housing 8 and the outer casing 6 are arranged in a trapezoidal shape, with the upper end receding forward and the lower end advancing backward. The water inlet 11 and the water outlet 12 are located on the rear side of the upper water channel rib 5. The bottom of the water outlet 12 is connected to the water outlet pipe 24. The bottom opening of the water outlet pipe 24 is located at the rear end of the lower water channel rib 5. The rear end of the lower water channel rib 5 abuts against the water outlet pipe 24. A gap is reserved between the front end of the water channel rib 5 and the outer casing 6.

[0038] When cooling water is injected through the inlet 11, it flows on the surface of the motor housing 8. The trapezoidal arrangement of the water channel ribs 5 allows the water to flow on the surface of the motor housing 8 at each water channel rib 5 position, forming a better coverage for heat absorption. The water that has absorbed heat flows down from the front end of the water channel ribs 5 and collects between the water channel ribs 5 below. It can then enter the outlet pipe 24. When the outlet pipe 24 is pulled out, the water that has absorbed heat below can be extracted, ensuring that the water can effectively absorb heat before being extracted.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
