Description

Technical Field

[0001] This invention relates to the field of automotive motor cooling, and more particularly to an adaptive automotive motor cooling device. Background Technology

[0002] With the rapid development of new energy vehicles, the motor of a car is the core driving component, and heat dissipation of the motor is particularly important. This will not only affect the performance and lifespan of the motor, but also directly affect the reliability and safety of the whole vehicle. Moreover, since the motor is often subjected to different load environments during the operation of a car, its heat dissipation requirements are also different under different load environments.

[0003] However, existing heat dissipation devices are not convenient for adjusting the heat dissipation intensity according to different environments, resulting in low heat dissipation performance and easy energy waste. They are also prone to significant reduction in heat dissipation capacity due to the accumulation of dust in the environment. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an adaptive automotive motor cooling device that is easier to adjust the heat dissipation intensity according to different environmental needs, avoids energy waste, and is less prone to dust accumulation, thereby improving heat dissipation performance.

[0005] The technical solution of the present invention is as follows: an adaptive automotive motor cooling device, comprising a mounting base plate, two legs fixedly connected to the mounting base plate, and side frames fixedly connected to each of the two legs. The side frames are hollow inside, and a connecting plate is fixedly connected between the two side frames. A placement hole is opened in the middle of the connecting plate. A connecting ring is fixedly connected between the two side frames. An upper plate and a lower plate are connected to the connecting ring by hinges. The lower plate and the upper plate are engaged by a locking mechanism. An automotive motor is placed between the two side frames. The side frames near the automotive motor are hollowed out. A groove is opened on the output shaft of the automotive motor. A wind-cooling mechanism is provided on the connecting plate to dissipate heat from the motor surface using airflow. A liquid-cooling mechanism is provided on the two side frames to improve heat dissipation efficiency. An adjustment mechanism is provided on the connecting plate to adjust the heat dissipation intensity.

[0006] As an improvement to the above solution, the air-cooling mechanism includes a support ring, which is fixedly connected to the connecting plate. A coupling cylinder is rotatably connected to the support ring. The inner wall of the coupling cylinder is provided with a protrusion, which cooperates with the groove on the output shaft of the automotive motor. Two air guide tubes are fixedly connected to the connecting plate. A positioning frame is fixedly connected to each of the two air guide tubes. A cooling fan is rotatably connected to each positioning frame. A first transmission wheel is fixedly connected to the coupling cylinder. A second transmission wheel is fixedly connected to each of the cooling fans. A transmission belt is wound between the two second transmission wheels and the first transmission wheel.

[0007] As an improvement to the above solution, the liquid cooling mechanism includes eight limiting posts, which are fixedly connected to the two side frames. Four limiting posts form a group, and a perforated plate is slidably connected between the four limiting posts in each group. The perforated plate has several perforations, and a support spring is connected between the perforated plate and the limiting posts. A heat-conducting plate is fixedly connected to each perforated plate, and the heat-conducting plate contacts the two side frames on both sides. A cooling pipe is fixedly connected to each perforated plate, and pipes are fixedly connected to both ends of each perforated plate. Two pipes on the same perforated plate form a group, and a circulating pump is fixedly connected to each perforated plate. One of the pipes in the same group is connected to the inlet of the adjacent circulating pump, and the other pipe is connected to one end of the adjacent cooling pipe. The other end of the cooling pipe is connected to the outlet of the circulating pump.

[0008] As an improvement to the above solution, the adjustment mechanism includes two support gears, both of which are rotatably connected to the connecting plate. A servo motor is fixedly connected to the connecting plate, and the drive shaft of the servo motor is connected to one of the support gears. Two positioning rods are fixedly connected to the connecting plate. An air guide ring is placed on the connecting plate, and two sliding grooves are opened on the air guide ring. The positioning rods are located in the sliding grooves on the air guide ring. Two fan-shaped holes are opened on the air guide ring, and two inclined surfaces are provided on the air guide ring. A gear plate is fixedly connected to the air guide ring, and the gear plate meshes with the two support gears. Two guide plates are fixedly connected to the air guide ring, and guide grooves are opened on the guide plates. A limit rod is fixedly connected to each heat conduction plate, and the limit rod is located in the guide groove on the guide plate.

[0009] As an improvement to the above solution, an air guiding mechanism is also included. The air guiding mechanism is disposed on the two side frames and is used to enhance the heat dissipation of the cooling pipe. The air guiding mechanism includes two straight pipes, which are fixedly connected to the side frames and communicate with the straight pipes inside the side frames. An air expansion pipe is fixedly connected to each side frame, and a connecting square pipe connects the air expansion pipe to the straight pipe. A connecting bent rod is slidably connected to each side frame. An air baffle is placed inside each straight pipe, and the air baffle has an air guiding slope. The air baffle is connected to one end of the connecting bent rod. An extrusion rod is fixedly connected to one side of each perforated plate, and an inclined groove is opened on the extrusion rod. The other end of the connecting bent rod is located in the inclined groove of the extrusion rod. Several partitions one, several partitions two, and one partition three are disposed inside the air expansion pipe.

[0010] 1. By adjusting the angle of the air guide ring, different levels of heat dissipation performance can be achieved. This makes it easier to select different heat dissipation intensities according to different scenario requirements, thus saving more energy.

[0011] 2. A portion of the air blown out by the cooling fan inside the side frame is guided by the baffle plate into the straight pipe, and then introduced into the expansion duct through the straight pipe and the connecting square pipe. It is then distributed and diffused through partition one, partition two and partition three, and blown out from the expansion duct. The blown air will pass over the cooling pipe, enhancing the cooling capacity of the cooling pipe and making it less likely for dust to accumulate on the cooling pipe and reduce its cooling capacity. This further improves the performance of liquid cooling. Attached Figure Description

The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0029] Example 1

[0030] An adaptive automotive motor cooling system, such as Figure 1-15As shown, the device includes a mounting base plate 1, on which two support legs 2 are fixedly connected. Each support leg 2 is fixedly connected to a side frame 31, which is hollow inside. A connecting plate 32 is fixedly connected between the two side frames 31, with a placement hole in the center of the connecting plate 32. A connecting ring 33 is fixedly connected between the two side frames 31, and an upper hinge plate 34 and a lower hinge plate 35 are connected to the connecting ring 33 via hinges. The lower hinge plate 35 and the upper hinge plate 34 are engaged by a locking mechanism. An automotive motor 4 is placed between the two side frames 31, with a hollowed-out side of the side frame 31 near the automotive motor 4. A groove is formed on the output shaft of the automotive motor 4. A wind-cooling mechanism is provided on the connecting plate 32 to dissipate heat from the motor surface using airflow. A liquid-cooling mechanism is provided on the two side frames 31 to improve heat dissipation efficiency. An adjustment mechanism is provided on the connecting plate 32 to adjust the heat dissipation intensity.

[0031] The air-cooling mechanism includes a support ring 51, which is fixedly connected to the connecting plate 32. A coupling cylinder 52 is rotatably connected to the support ring 51. The inner wall of the coupling cylinder 52 is provided with a protrusion, which cooperates with the groove on the output shaft of the automotive motor 4. Two air guide tubes 53 are fixedly connected to the connecting plate 32. A positioning frame 54 is fixedly connected to each of the two air guide tubes 53. A cooling fan 55 is rotatably connected to each positioning frame 54. A first transmission wheel 56 is fixedly connected to the coupling cylinder 52. A second transmission wheel 57 is fixedly connected to each cooling fan 55. A transmission belt 58 is wound between the two second transmission wheels 57 and the first transmission wheel 56.

[0032] The liquid cooling mechanism includes eight limiting posts 61, which are fixedly connected to two side frames 31. Four limiting posts 61 form a group, and a perforated plate 62 is slidably connected between each group of four limiting posts 61. The perforated plate 62 has several perforations, and a support spring 63 connects the perforated plate 62 to the limiting posts 61. A heat-conducting plate 64 is fixedly connected to each perforated plate 62, and both sides of the heat-conducting plate 64 contact the two side frames 31. Cooling pipes 65 are fixedly connected to each perforated plate 62. Pipes 66 are fixedly connected to both ends of each perforated plate 62. Two pipes 66 on the same perforated plate 62 form a group. A circulation pump 67 is fixedly connected to each perforated plate 62. One of the pipes 66 in the same group is connected to the inlet of the adjacent circulation pump 67, and the other pipe 66 is connected to one end of the adjacent cooling pipe 65. The other end of the cooling pipe 65 is connected to the outlet of the circulation pump 67.

[0033] The adjustment mechanism includes two support gears 71, both of which are rotatably connected to the connecting plate 32. A servo motor 72 is fixedly connected to the connecting plate 32, and the drive shaft of the servo motor 72 is connected to one of the support gears 71. Two positioning rods 730 are fixedly connected to the connecting plate 32. An air guide ring 73 is placed on the connecting plate 32, and the air guide ring 73 has two sliding grooves. The positioning rods 730 are located in the sliding grooves on the air guide ring 73. The air guide ring 73 has two fan-shaped holes and two inclined surfaces. A gear disk 74 is fixedly connected to the air guide ring 73, and the gear disk 74 meshes with the two support gears 71. Two guide plates 75 are fixedly connected to the air guide ring 73, and the guide plates 75 have guide grooves. Each heat-conducting plate 64 is fixedly connected to a limit rod 76, which is located in the guide groove on the guide plate 75.

[0034] In actual operation, the cooling pipe 65 and the perforated plate 62 are filled with coolant. Then, the upper plate 34 and the lower plate 35 can be opened to remove or install the car motor 4 into the side frame 31. After installation, the output shaft of the car motor 4 is inserted into the coupling cylinder 52. Initially, the air guide ring 73 blocks the connection between the air guide cylinder 53 and the side frame 31. The servo motor 72 is started, which drives the support gear 71 to rotate, thereby driving the gear plate 74 and the air guide ring 73 to rotate at a certain angle, so that the fan-shaped hole on the air guide ring 73 connects the air guide cylinder 53 and the side frame 31. Then, the servo motor 72 is turned off. At this time, after the car motor 4 starts, it will pass through the coupling cylinder 52. The drive wheel 56 drives the cooling fan 55 to rotate at high speed. The rotation of the cooling fan 55 blows air into the side frame 31 through the air guide tube 53 and out from the other end of the side frame 31. The flowing air will cool the two sides of the car motor 4. When the power of the car motor 4 increases, the heat generated is also greater. Then the servo motor 72 can be started to drive the support gear 71 to continue to rotate a certain angle, so that the air guide ring 73 continues to rotate a certain angle. After the air guide ring 73 continues to rotate a certain angle, it will drive the guide plate 75 to press the two limit rods 76 to move closer to each other, thereby driving the two heat conduction plates 64 to move closer to the surface of the car motor 4. The system moves until the two heat-conducting plates 64 come into contact with the surface of the car motor 4. Then, the circulation pump 67 is activated, causing the coolant in the cooling pipe 65 and the perforated plate 62 to circulate in one direction. The heat generated by the car motor 4 is transferred through the heat-conducting plates 64 to the perforated plate 62, and then to the coolant. The coolant then circulates back to the cooling pipe 65 for heat dissipation. This cycle completes the liquid cooling of the car motor 4, further enhancing its heat dissipation performance. By adjusting the angle of the air guide ring 73, different levels of heat dissipation performance can be achieved. This allows for selection of different heat dissipation intensities according to different scenario requirements, resulting in greater energy savings. Then, when in... In low-temperature environments, the heat dissipation requirements of the car motor 4 decrease, and it may even need to maintain a certain operating temperature. At this time, the servo motor 72 can be started to drive the air guide ring 73 to rotate in the opposite direction and reset, so that the air guide ring 73 blocks the connection between the air guide tube 53 and the side frame 31. The heat conduction plate 64 moves away from the car motor 4 and the circulation pump 67 is turned off, so that a cavity appears between the heat conduction plate 64 and the surface of the car motor 4. Then, a cavity is also formed between the side frame 31 and the car motor 4. The air blown into the air guide tube 53 by the cooling fan 55 will be discharged by the inclined surface on the air guide ring 73 and will no longer be blown into the side frame 31. At this time, the cavity around the car motor 4 can keep it warm to a certain extent.

[0035] Example 2

[0036] Based on Example 1, such as Figure 12-15As shown, it also includes an air guiding mechanism, which is disposed on the two side frames 31. The air guiding mechanism is used to enhance the heat dissipation of the cooling pipe 65. The air guiding mechanism includes two straight pipes 81, which are fixedly connected to the side frames 31. The inside of the side frames 31 communicates with the straight pipes 81. Each side frame 31 is fixedly connected to an air expansion pipe 82. A connecting square pipe 83 connects the air expansion pipe 82 and the straight pipe 81. Each side frame 31 has a sliding... A connecting bent rod 84 is connected to each of the straight pipes 81, and a baffle plate 85 is placed inside each of the straight pipes 81. The baffle plate 85 has a guide slope. One end of the baffle plate 85 is connected to the connecting bent rod 84. A pressing rod 86 is fixedly connected to one side of each perforated plate 62. The pressing rod 86 has a slanted groove. The other end of the connecting bent rod 84 is located in the slanted groove of the pressing rod 86. Several partition plates 871, several partition plates 872 and one partition plate 873 are provided inside the air expansion pipe 82.

[0037] When the air guide ring 73 drives the guide plate 75 to continue rotating at a certain angle and squeezes the limiting rod 76 to drive the two heat conduction plates 64 to move towards each other, the two heat conduction plates 64 will drive the squeezing rod 86 to move longitudinally a certain distance. The squeezing rod 86 will squeeze the connecting bent rod 84 to move horizontally, thereby driving the air baffle 85 to move horizontally towards the car motor 4, so that part of the air baffle 85 enters the side frame 31. Then, part of the air blown out by the cooling fan 55 in the side frame 31 will be guided by the air guide slope on the air baffle 85 to the straight pipe 81, and then introduced into the air expansion pipe 82 through the straight pipe 81 and the connecting square pipe 83. Then, it will be diverted and diffused by the first partition 871, the second partition 872 and the third partition 873, and blown out from the air expansion pipe 82. The blown air will blow over the cooling pipe 65, enhance the heat dissipation capacity of the cooling pipe 65, and prevent dust from accumulating on the cooling pipe 65 and reducing its heat dissipation capacity. This further improves the performance of liquid cooling.
