Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor and electronic control heat dissipation technology, and in particular to an integrated heat dissipation device for motor and electronic control. Background Technology
[0002] During the operation of motors and electronic control systems, their internal electronic components and mechanical structures continuously generate heat. If the heat cannot be dissipated in time, the system temperature will rise, which will lead to a decrease in motor efficiency, a shortened lifespan of electronic control components, and even a failure to shut down. Therefore, an efficient heat dissipation device is crucial for the stable operation of motor and electronic control systems.
[0003] Chinese Patent Publication No. CN222356820U discloses a heat dissipation device for an air-cooled chiller control box, relating to the field of control box technology. The device includes a box body, a fan fixedly installed at the center of the right side of the box body, several air inlets extending through the left side of the box body, a temperature sensor fixedly installed on the upper inside of the box body, and sliding grooves fixedly connected to both the upper and lower ends of the left side of the box body. Sliding frames are slidably connected inside the two sets of sliding grooves, and a first filter screen is fixedly connected inside the sliding frames. A stop bar is rotatably connected to the left front end of the upper sliding groove. This invention, by setting a first filter screen, air inlets, and a second filter screen, prevents external dust from entering the control box through the heat dissipation holes and causing damage to electronic components. By setting the sliding grooves, sliding frames, second handle, and stop bar, when dust adheres to the filter screen surface and obstructs air circulation, it is convenient to disassemble the filter screen for dust cleaning, thereby improving heat dissipation efficiency.
[0004] The aforementioned patent documents still have the following defects in practice:
[0005] Relying solely on the "fan + air inlet" pure air-cooling mode, when the chiller's electrical control box is running under high load, the heat generated by the electronic components inside the box will far exceed the air-cooling system's dissipation capacity. This causes the temperature sensor to detect that the internal temperature of the box is consistently higher than the safety threshold, which in turn leads to a decrease in the control accuracy of the electrical control box, and may even result in the component overheating protection shutdown. Utility Model Content
[0006] The main objective of this invention is to provide an integrated heat dissipation device for motor control, which can effectively solve the problems mentioned above.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] An integrated heat dissipation device for motor control includes a blower mechanism, an air-guiding mechanism at the rear of the blower mechanism, a heat-absorbing mechanism at the front of the blower mechanism, and a heat dissipation mechanism in the middle of the heat-absorbing mechanism.
[0009] Preferably, the blower mechanism includes a fixing plate, an L-shaped fixing plate is provided at the rear of the fixing plate, and a fan is provided in the middle of the L-shaped fixing plate.
[0010] Preferably, the heat absorption mechanism includes two fixed frames, the lower parts of the two fixed frames are jointly arranged on the upper part of a fixed plate, each of the two fixed frames has several strip grooves on the side close to each other, the inner cavity of the fixed frame is provided with several guide plates, the rear of the two fixed frames is jointly provided with a water inlet pipe, and the front of the two fixed frames is jointly provided with a water outlet pipe.
[0011] Preferably, one end of the guide plate is connected to the fixed frame, and the other end is provided with an opening. The openings of the guide plates are staggered, and the opening end of the guide plate is lower than the connecting end.
[0012] Preferably, the heat dissipation mechanism includes a water tank and several horizontal fins. The water tank is disposed on the upper part of a fixed plate, and the several horizontal fins are disposed between two fixed frames through several strip grooves. The lower part of the lowest horizontal fin is provided with several vertical fins.
[0013] Preferably, the heat dissipation mechanism includes a water pump, which is located at the lower part of the water inlet pipe and inside the water tank.
[0014] Preferably, the air-guiding mechanism includes two L-shaped rotating plates, which are respectively disposed on the left and right sides of the L-shaped fixed plate. A pin is provided on the upper part of the L-shaped rotating plate, and a spring is provided between the pin and the L-shaped rotating plate.
[0015] Preferably, the air-guiding mechanism includes four circular grooves, which are disposed on the upper part of the L-shaped fixing plate.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This device integrates the liquid cooling circulation of the heat absorption mechanism with the forced air cooling of the blower mechanism to form a complete closed loop of "heat absorption - heat conduction - heat dissipation". In the heat absorption mechanism, after the coolant enters the fixed frame through the inlet pipe, it is guided by the staggered and inclined guide plates, which not only extends the flow path but also ensures full contact with the inner wall of the fixed frame and the horizontal fins, maximizing the absorption of heat transferred from the motor and the control box. After absorbing heat, the coolant flows back to the water tank through the outlet pipe. The horizontal fins are embedded in the fixed frame through the strip grooves, which can simultaneously contact the warm coolant and the fan airflow, quickly transferring heat to the air. The vertical fins of the lowest horizontal fins extend into the water tank, which can also accelerate the pre-heat dissipation of the coolant in the water tank, further improving the circulation cooling efficiency. Compared with the traditional pure air cooling method that relies solely on air convection for heat dissipation, this device can effectively control the temperature even under high load operation of the motor and control and a surge in heat generation, avoiding efficiency reduction, shortened component life or shutdown problems caused by heat accumulation.
[0018] 2. This device, through its designed air-guiding mechanism, allows for the adjustment of the L-shaped rotating plate in conjunction with the pin, spring, and circular groove, enabling flexible control of the airflow direction. During use, the angle of the L-shaped rotating plate can be adjusted by pulling out the pin and fixing it in the corresponding circular groove. One rotating plate guides the fan airflow directly towards the motor, compensating for the limited heat dissipation blind spot on the contact surface between the motor and the heat-absorbing mechanism, thus achieving precise air cooling of the motor. The other rotating plate blocks excess airflow outlets, preventing airflow loss and ensuring that most of the airflow is concentrated on the motor and heat dissipation mechanism (horizontal fins and vertical fins), further improving the air cooling utilization rate and enhancing the cooling effect of the core heat source.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Example 1, as Figure 1 - Figure 2 As shown, an integrated heat dissipation device for motor control includes a blower mechanism 5, an air-guiding mechanism 4 at the rear of the blower mechanism 5, a heat-absorbing mechanism 2 at the front of the blower mechanism 5, and a heat dissipation mechanism 6 in the middle of the heat-absorbing mechanism 2.
[0027] In this embodiment, the device is placed between the motor 3 and the electrical control box 1. The air-drawing mechanism 4 is adjusted, and the blower mechanism 5 and the heat dissipation mechanism 6 are started. The coolant is drawn into the heat absorption mechanism 2, the heat is absorbed and transferred to the heat dissipation mechanism 6, and then the heat on the heat dissipation mechanism 6 and the motor 3 is dissipated by the blower mechanism 5.
[0028] To improve heat dissipation efficiency, the blower mechanism 5 includes a fixing plate 51, an L-shaped fixing plate 52 at the rear of the fixing plate 51, and a fan 53 in the middle of the L-shaped fixing plate 52.
[0029] During implementation, the fan 53 is started to generate airflow to dissipate heat and cool down the heat dissipation mechanism 6 and the motor 3. The fixing plate 51 provides a mounting surface for the device and fixes the device in the required position. The L-shaped fixing plate 52 supports the air-expelling mechanism 4.
[0030] Example 2: To dissipate heat from motor 3 and control box 1, see [reference needed]. Figure 3 The heat absorption mechanism 2 includes two fixed frames 21. The lower parts of the two fixed frames 21 are jointly set on the upper part of the fixed plate 51. Several strip grooves 22 are provided on the side of the two fixed frames 21 that are close to each other. Several guide plates 23 are provided in the inner cavity of the fixed frame 21. The rear part of the two fixed frames 21 is jointly provided with a water inlet pipe 24. The front part of the two fixed frames 21 is jointly provided with a water outlet pipe 25. One end of the guide plate 23 is connected to the fixed frame 21, and the other end is provided with an opening. The openings of the several guide plates 23 are staggered. The opening end of the guide plate 23 is lower than the connecting end.
[0031] During implementation, the coolant enters the inner cavity of the two fixed frames 21 through the inlet pipe 24. Under the guidance of the guide plate 23, it fully contacts the inner wall of the fixed frame 21 and the horizontal fins 64, absorbing the heat transferred from the motor 3 to the heat absorption mechanism 2. After completing the heat absorption process, it flows back to the water tank 62 through the outlet pipe 25. The guide plate 23 extends the flow path of the coolant through the staggered opening design, and the opening end is lower than the connection end, so gravity can be used to assist the flow of coolant. The strip groove 22 provides an insertion channel for the horizontal fins 64, ensuring that the horizontal fins 64 are stably installed and precisely matched.
[0032] To rapidly cool the coolant, refer to Figure 4 The heat dissipation mechanism 6 includes a water tank 62 and several horizontal fins 64. The water tank 62 is located on the upper part of the fixed plate 51. Several horizontal fins 64 are arranged between two fixed frames 21 through several strip grooves 22. Several vertical fins 63 are provided below the lowest horizontal fin 64. The heat dissipation mechanism 6 includes a water pump 61. The water pump 61 is located below the water inlet pipe 24 and is located inside the water tank 62.
[0033] During implementation, the horizontal fins 64 extend halfway into the fixed frame 21 and simultaneously come into contact with the warm coolant and the airflow generated by the fan, transferring the absorbed heat to the surrounding air. The vertical fins 63 on the lowest horizontal fins 64 extend into the water tank 62, drawing out the heat from the liquid in the water tank 62, accelerating the dissipation of heat into the air, rapidly reducing the temperature of the horizontal fins 64, and returning the warm coolant to the water tank 62. After completing the initial heat dissipation in the water tank 62, it is drawn back by the water pump 61 and enters the next cycle.
[0034] To improve heat dissipation for motor 3, see [reference needed]. Figure 5 The air-guiding mechanism 4 includes two L-shaped rotating plates 41, which are respectively arranged on the left and right sides of the L-shaped fixed plate 52. The upper part of the L-shaped rotating plate 41 is provided with a pin 42, and a spring 43 is provided between the pin 42 and the L-shaped rotating plate 41. The air-guiding mechanism 4 includes four circular grooves 44, which are arranged on the upper part of the L-shaped fixed plate 52.
[0035] During implementation, in order to make the airflow generated by the fan 53 flow towards the air-drawing mechanism 4, the pin 42 is pulled out, rotated to a suitable position, and then inserted into the corresponding circular groove 44 to fix the angle of the L-shaped rotating plate 41. The open L-shaped rotating plate 41 guides the airflow directly to the motor 3, making up for the limited contact area between the motor 3 and the heat absorption mechanism 2, and realizing the air cooling of the motor 3. The other side of the L-shaped rotating plate 41 blocks the airflow outlet to prevent the airflow from being lost, ensuring that most of the airflow acts on the heat dissipation of the motor 3 and the heat dissipation mechanism 6.
[0036] It should be noted that the specific installation method, circuit connection method, and control method of the fan 53 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
