Description

TECHNICAL FIELD

[0001] The present application relates to the field of high-power motor heat dissipation technology, and in particular to a high-power motor heat dissipation system. BACKGROUND

[0002] Currently, large motors used in industrial production generate a large amount of heat due to their high power and heavy load. If this heat is not effectively dissipated in time, the motor will overheat, reducing efficiency and even damaging the equipment. Therefore, an efficient heat dissipation system is crucial for ensuring the normal operation of high-power motors. Traditional cooling methods include natural air cooling, forced air cooling, and liquid cooling. Natural air cooling is less efficient and not suitable for high-temperature environments. Although liquid cooling is effective, it is costly and complex to maintain.

[0003] Existing heat dissipation measures mostly use forced air cooling methods, which use fans or blowers to force air flow to carry away the heat generated by the motor. However, this method usually faces two main problems. First, the complex internal structure of the motor leads to uneven airflow distribution, and some parts may not be effectively cooled. Second, the fan is prone to wear and tear after long-term operation, reducing the reliability and service life of the entire system. In addition, a common method is to place the motor in a sealed cavity and use heat-conducting fins to conduct heat to the outside air to achieve cooling. This method can improve the temperature to some extent, but the actual heat dissipation effect is not ideal due to the long heat conduction path.

[0004] In summary, both natural air cooling and forced air cooling, as well as liquid cooling methods, have certain limitations and cannot fully meet the needs of modern industrial production for efficient and stable heat dissipation of high-power motors.

[0005] Therefore, the present application proposes a high-power motor heat dissipation system. Content of the utility model

[0006] The application provides a high-power motor heat dissipation system to solve the problems in the background art. The system adopts a design concept of a rear-inclined axial fan, a flow guide cover, heat dissipation fins and an intelligent control system. The traditional forced air cooling mode is improved, the overall heat dissipation efficiency is improved, the maintenance process is simplified and the service life is prolonged. In a specific application example, compared with a common air cooling system, the new scheme can significantly improve the cooling range by more than 25% under the same energy consumption, effectively avoids the occurrence of local hot spots and greatly enhances the safety and reliability of the equipment. Compared with the prior art, the technical effects of the technical scheme are as follows. The traditional air cooling technology is improved and innovated, the overall heat dissipation performance is more excellent, the original complex maintenance process is simplified, the later operation cost is significantly reduced, the intelligent temperature control mechanism is introduced, the system can flexibly cope with various complex working conditions, the automatic management level is improved and the practicability of the device is greatly improved.

[0007] In order to achieve the above-mentioned purpose, the application adopts the following technical scheme:

[0008] The high-power motor heat dissipation system comprises a motor, a rear-inclined axial fan, a flow guide cover, heat dissipation fins and a control system. The rear-inclined axial fan is arranged coaxially with the motor at the tail of the motor. The flow guide cover is tightly attached to the surface of the motor shell to form a closed channel. The heat dissipation fins are evenly distributed around the motor shell and located inside the flow guide cover. The rear-inclined axial fan comprises a rotating drum and blades. The rotating drum is rotatably connected inside the rear-inclined axial fan. The rotating drum is externally provided with a plurality of blades.

[0009] As a preferred embodiment, the control system is electrically connected with the motor and the rear-inclined axial fan.

[0010] The control system is used for monitoring the running state of the motor and adjusting the rotating speed of the rear-inclined axial fan in real time, so that the best heat dissipation effect is ensured and unnecessary energy consumption is reduced, thereby improving the practicability of the device.

[0011] As a preferred embodiment, a filter screen device is additionally arranged at the air inlet of the flow guide cover. The filter screen device comprises a mounting cylinder, an annular frame, a screen body, a first thread, a second thread, a mounting groove, a spring, an arc-shaped positioning piece and a positioning hole.

[0012] The filter screen device is additionally arranged at the air inlet of the flow guide cover, so that impurities are prevented from entering the inside and affecting the heat dissipation effect, thereby improving the practicability of the device.

[0013] As a preferred implementation form, the mounting cylinder is fixedly connected at the air inlet of the fairing, the inside of the mounting cylinder is detachably connected with the annular frame, and the inside of the annular frame is provided with the net body.

[0014] By setting the annular frame and the mounting cylinder as detachable, the net body can be detached from the mounting cylinder through the annular frame, which is beneficial to cleaning the dust on the net body regularly, improving the air volume, and thus improving the practicability of the device.

[0015] As a preferred implementation form, the mounting cylinder and the annular frame are provided with a first thread and a second thread, the first thread is arranged on the mounting cylinder, the second thread is arranged on the annular frame, and the annular frame is threadedly connected with the mounting cylinder through the first thread and the second thread.

[0016] By arranging the first thread and the second thread on the mounting cylinder and the annular frame, the annular frame can be quickly detached from and mounted on the mounting cylinder, which improves the mounting and detaching efficiency, and thus improves the practicability of the device.

[0017] As a preferred implementation form, the inside of the annular frame is provided with a plurality of mounting grooves, the inside of each mounting groove is provided with a spring, and one end of each spring is fixedly connected with an arc-shaped positioning piece.

[0018] By arranging a plurality of mounting grooves in the annular frame and arranging a spring in each mounting groove, the spring is installed, and thus the practicability of the device is improved.

[0019] As a preferred implementation form, the inside of the mounting cylinder is provided with a plurality of positioning holes, and the side of each arc-shaped positioning piece away from the spring extends into the inside of the positioning hole.

[0020] By arranging the arc-shaped positioning piece and the positioning hole, after the annular frame is connected with the mounting cylinder through the first thread and the second thread, each arc-shaped positioning piece is automatically clamped into the corresponding positioning hole, which has a positioning effect on the mounted annular frame, and thus the practicability of the device is improved.

[0021] As a preferred implementation form, the outside of each blade is provided with a sound-absorbing coating, and the sound-absorbing coating is evenly coated on the blade.

[0022] By arranging the sound-absorbing coating, for some special occasions requiring quieter operation, the sound-absorbing coating can be coated on the ventilation blade to further reduce the noise level, and thus the practicability of the device is improved.

[0023] The beneficial effects of the present application are as follows:

[0024] 1. The high-power motor cooling system adopts the design concept of rear inclined axial fan, fairing, cooling fin and intelligent control system, improves the traditional forced air cooling method, improves the overall cooling efficiency, simplifies the maintenance process and prolongs the service life. In specific application examples, compared with the ordinary air cooling system, the new scheme can significantly improve the cooling amplitude by more than 25% under the same energy consumption, effectively avoid the occurrence of local hot spots, and greatly enhance the safety and reliability of the equipment. Compared with the prior art, the technical effects of the technical scheme are as follows: the traditional air cooling technology is improved and innovated to realize more excellent overall cooling performance, simplify the original complex and tedious maintenance process, significantly reduce the later operation cost, introduce intelligent temperature control mechanism, make the system can flexibly cope with various complex working conditions, improve the automation management level, and greatly improve the practicability of the device.

[0025] 2. The high-power motor cooling system, when the motor starts, the control system detects the current load condition and adjusts the speed of the rear inclined axial fan to produce appropriate strength airflow. The airflow is guided by the fairing and moves along the annular path formed by the cooling fin, taking away most of the heat generated by the motor. As the temperature changes, the control system automatically adjusts the parameters to maintain a constant cooling rate. Considering that there may be a lot of dust in the actual application environment, a filter screen device is added at the air inlet of the fairing to prevent impurities from entering the interior and affecting the cooling effect. In addition, for some special occasions that require quieter operation, an acoustic coating can be applied to the ventilation blades to further reduce noise levels, greatly improving the practicability of the device.
