Description

A high-efficiency heat dissipation device for permanent magnet synchronous motors Technical Field

[0001] This invention belongs to the technical field of permanent magnet synchronous motors, and more specifically, it relates to a high-efficiency heat dissipation device for permanent magnet synchronous motors. Background Technology

[0002] Permanent magnet synchronous motors (PMSMs) have advantages such as simple structure, small size, high efficiency, reliable operation, wide speed range, and good dynamic and static characteristics, and are widely used in AC drive systems. However, PMSMs generate a lot of heat during operation, which is difficult to dissipate and affects the motor's service life.

[0003] Therefore, heat dissipation is a key factor affecting the performance and operational stability of permanent magnet synchronous motors. However, existing heat dissipation structures for permanent magnet motors still have the following shortcomings:

[0004] Existing heat dissipation structures or devices for permanent magnet motors typically use heat exchange materials or airflow to dissipate heat from their surfaces. However, their actual heat dissipation effect is generally limited and cannot efficiently solve the heat generation problem of permanent magnet motors.

[0005] The existing technology lacks highly integrated processing equipment for heat dissipation of permanent magnet motors. The operation of permanent magnet motors generates a lot of heat, which causes the body temperature to gradually increase. The conventional heat dissipation method of ordinary permanent magnet motors usually uses a fan to dissipate airflow to cool the main components, while using temperature sensors and other control structures to monitor the safety. However, the cooling effect of air cooling alone on the temperature around the piston needs to be improved, which makes it easy for the efficiency of the permanent magnet motor and its normal operation to be affected by the cooling efficiency during operation.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a high-efficiency heat dissipation device for permanent magnet synchronous motors, in order to achieve a more practical purpose. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention discloses a high-efficiency heat dissipation device for permanent magnet synchronous motors, which features a more efficient airflow heat dissipation function. By setting an airflow heat dissipation structure in the heat dissipation box in conjunction with an exhaust fan, the exhaust fan rotates at high speed during the operation of the permanent magnet synchronous motor, causing external airflow to enter the heat dissipation housing. This effectively blows and dissipates heat from the permanent magnet synchronous motor, preventing heat accumulation. Simultaneously, through the air inlet port at the bottom of the auxiliary heat dissipation cylinder and the internal heat dissipation cavity, the airflow continues to flow upward through the air inlet port while flowing at the bottom. Combined with the blowing channel, this dissipates heat from the outer wall of the permanent magnet synchronous motor, achieving a highly efficient airflow heat dissipation effect. Furthermore, the top of the auxiliary heat dissipation cylinder is connected to the output nozzles at the top of the top end cover via a connecting cavity ring. This allows the airflow to finally be blown towards the top end cover through the output nozzles and then dissipated upward through the airflow exhaust channel, thereby achieving a highly efficient airflow heat dissipation effect for the permanent magnet synchronous motor, improving heat dissipation efficiency, and significantly enhancing the cooling effect of the machine body.

[0021] This invention provides a high-efficiency heat dissipation device for permanent magnet synchronous motors. It not only features efficient airflow cooling but also incorporates a liquid circulation-type heat conduction cooling function that adheres to the surface. Through the liquid circulation tank and the liquid circulation cooling structure, the pump inside the liquid circulation tank is activated, supplying coolant to the input ring plate via a cooling input pipe. The coolant is then transferred from the input ring plate into the liquid flow chamber through a one-way inlet valve and returned to the liquid circulation tank via a one-way outlet valve and a connecting port, through the output port and a cooling return pipe. This liquid circulation, combined with the heat-conducting metal arc sheet adhering to the outer wall of the permanent magnet synchronous motor, achieves efficient cooling of the permanent magnet... The outer wall of the synchronous motor facilitates heat transfer, thereby further improving the heat dissipation efficiency of the permanent magnet synchronous motor and avoiding the problem of heat dissipation difficulties caused by high-frequency operation of the permanent magnet synchronous motor. At the same time, the heat dissipation bonding plate not only achieves liquid circulation heat dissipation, but also creates a gap between the auxiliary heat dissipation cylinder and the permanent magnet synchronous motor. This gap, combined with the airflow heat dissipation effect, greatly improves the airflow efficiency, thereby further improving the heat dissipation efficiency. Furthermore, the input ring plate and output ring plate are set in the heat dissipation cavity, which, together with the airflow effect, also improves the liquid heat dissipation efficiency, thus improving the liquid circulation cooling efficiency.

[0049] The specific working steps of this invention are as follows:

[0050] The present invention provides a high-efficiency heat dissipation device for a permanent magnet synchronous motor, which has a more efficient airflow heat dissipation function. By setting an airflow heat dissipation structure in the heat dissipation box 15 in conjunction with the exhaust fan, the exhaust fan rotates at high speed during the operation of the permanent magnet synchronous motor 35, so that external airflow is input into the heat dissipation housing 11, which blows and dissipates heat from the internal permanent magnet synchronous motor 35 and avoids the problem of internal heat accumulation. At the same time, through the air inlet port 42 at the bottom of the auxiliary heat dissipation cylinder 41 and the internal heat dissipation air cavity 43, the airflow can be effectively circulated at the bottom. The air continues to be transmitted upward through the air inlet port 42, and in conjunction with the blowing channel 44, it adheres to and drives the heat dissipation of the outer wall of the permanent magnet synchronous motor 35, achieving a highly efficient airflow cooling effect for the permanent magnet synchronous motor 35. Furthermore, the top of the auxiliary heat dissipation cylinder 41 is connected to each output nozzle 64 on the top of the top end cover 51 through the connecting cavity ring 55, so that the airflow is finally blown towards the top end cover 51 through the output nozzles 64 and then dissipated upward through the airflow dissipation channel, thereby achieving a highly efficient airflow cooling effect for the permanent magnet synchronous motor 35, improving the heat dissipation efficiency, and thus greatly improving the cooling effect of the machine body.

[0051] This invention provides a high-efficiency heat dissipation device for a permanent magnet synchronous motor. It not only features efficient airflow heat dissipation but also incorporates a liquid circulation heat conduction function that adheres to the surface. Through the liquid circulation tank and the liquid circulation heat dissipation structure, the pump inside the liquid circulation tank is activated, supplying coolant to the input ring plate 47 via the cooling input pipe 68. The coolant is then transferred from the input ring plate 47 to the liquid flow chamber 37 through the one-way inlet valve 45 and returned to the liquid circulation tank via the one-way outlet valve 46, the docking port 60, the output port 50, and the cooling return pipe 70. This liquid circulation, combined with the heat-conducting metal arc plate 38 adhering to the outer wall of the permanent magnet synchronous motor 35, achieves efficient heat dissipation of the permanent magnet. The outer wall of the synchronous motor 35 facilitates heat transfer, thereby further improving the heat dissipation efficiency of the permanent magnet synchronous motor 35 and avoiding the problem of heat dissipation difficulties caused by high-frequency operation of the permanent magnet synchronous motor 35. At the same time, the setting of the heat dissipation bonding plate 34 not only achieves the liquid circulation heat dissipation effect, but also the structure of the heat dissipation bonding plate 34 creates a gap space 65 between the auxiliary heat dissipation cylinder 41 and the permanent magnet synchronous motor 35. The gap setting, combined with the airflow heat dissipation effect, greatly improves the airflow efficiency, thereby further improving the heat dissipation efficiency. In addition, the input ring plate 47 and the output ring plate 49 are set in the heat dissipation cavity 43, which, together with the airflow effect, also improve the liquid heat dissipation efficiency, thereby improving the liquid circulation cooling efficiency.
