[0002] The automotive motor cooling device with integrated intelligent temperature control system is an advanced thermal management system designed specifically for the motors and electronic control systems in new energy vehicles. This device not only includes traditional cooling components such as radiators, coolant, water pumps, and fans, but also integrates intelligent control technology to achieve more efficient and precise temperature control.

[0003] The automotive motor cooling device with integrated intelligent temperature control system is an important development direction in the field of thermal management of new energy vehicles. It helps to improve the performance, reliability and driving comfort of the whole vehicle.

[0004] Existing devices and systems for cooling automotive motors through coolant circulation suffer from certain waste issues in practical applications. Simply cooling the radiator with a cooling fan is insufficient, as it is difficult to utilize the heat from the antifreeze flowing through the heat exchange pipes. Therefore, this paper proposes an automotive motor cooling device and its usage method that integrates an intelligent temperature control system to address these problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automotive motor cooling device and its usage method that integrates an intelligent temperature control system, in order to solve the problem that existing devices and systems that cool automotive motors by circulating coolant have certain waste issues in practical applications. They simply rely on cooling fans to cool the radiator and it is difficult to utilize the heat inside the antifreeze flowing through the heat exchange pipes.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A car motor cooling device with an integrated intelligent temperature control system and its usage method are disclosed.

A first gear is fixedly connected to one end of the first rotating shaft. The first gear and the second gear are connected by a drive mechanism. Guide rods are installed on both sides of the drive mechanism. A protective housing is installed outside the drive mechanism. A sealing frame is installed on one side of the lower end of the sealing plate. An exhaust port is opened on one side of the sealing frame. A rubber ring is installed on the lower side of one end of the circulating housing, and a heat exchange tube is installed below the rubber ring.

[0009] As a further optimization of the present invention, the driving mechanism includes a fixed base, an electric push rod is fixedly connected to the inner side of the fixed base, a vertical plate is fixedly connected to the moving end of the electric push rod, a first toothed plate is fixedly connected to the upper end of the vertical plate, and a second toothed plate is fixedly connected to the lower end of the vertical plate. Positioning holes are provided inside both the first toothed plate and the second toothed plate.

[0010] As a further optimization of the present invention, the first toothed plate and the second toothed plate are parallel to each other, the included angle between the first toothed plate and the vertical plate is 90°, the upper end of the first toothed plate meshes with the second gear, the lower end of the second toothed plate meshes with the first gear, and both the first toothed plate and the second toothed plate are slidably connected to the guide rod through positioning holes opened inside.

[0011] As a further optimization of the present invention, the heat exchange tube includes an aluminum tube, and connecting flanges are welded and fixed to the outer sides of both ends of the aluminum tube, and heat dissipation fins are welded and fixed to the outer side of the middle of the aluminum tube.

[0012] As a further optimization of the present invention, the connecting flange is welded and fixed to the circulating shell, a plurality of heat dissipation fins are provided, the heat dissipation fins are arranged in a ring and are disposed inside the circulating shell, and the aluminum pipe is connected to the water pipe.

[0013] As a further optimization of the present invention, the water pipe is provided in multiple parts, the water pipe connecting the radiator and the electric water pump is connected to the water inlet of the electric water pump, the water pipe connecting the electric water pump and the drive motor is connected to the water inlet of the electric water pump, and the expansion tank is connected to the upper and lower ends of one side of the radiator through two water pipes respectively.

[0014] As a further optimization of the present invention, the recirculating outer shell is U-shaped, and the recirculating outer shell and the protective outer shell are fixedly connected by rivets. There are two baffles, the lower end of the baffles is semi-circular, the baffles are parallel to each other, and the baffles are fixedly connected to the protective outer shell by rivets.

[0015] As a further optimization of the present invention, the openings on both sides of the upper end of the circulating shell are connected to the interior of the car body, and the interior of the circulating shell is connected to the air conditioning low-pressure pipe through a rubber ring. There are two rubber rings, and the vertical cross-section of the rubber ring is "I" shaped.

[0016] As a further optimization of the present invention, the following features are provided: two fixed seats are provided, the fixed seats are fixedly connected to the baffle by bolts, the fixed seats are fixedly connected to the fixed end of the electric push rod, and the included angle between the electric push rod and the vertical plate is 90°.

[0017] As a further optimization of the present invention, the following steps are included: Step I: System operation, optimizing the heat dissipation effect by using the fan unit in conjunction with the air conditioning low-pressure pipe and the in-vehicle environment: During this process, the fan unit draws air with a lower temperature than the outside temperature from the in-vehicle air conditioning environment. This air is further cooled by the air conditioning low-pressure pipe and then exchanges heat with the heat exchange pipe to cool the coolant flowing through the heat exchange pipe, thereby further improving the heat dissipation effect of the vehicle drive motor and ensuring that the vehicle drive motor can operate more stably. During the process, the cooling air is directly discharged to the outside of the vehicle through the exhaust port, and the fan unit only works after the air conditioning inside the vehicle is running.

[0018] Step II: Optimize the in-vehicle environment through water pipes: The electric push rod moves the vertical plate. During the movement of the vertical plate, the first toothed plate and the second toothed plate move synchronously, which in turn drives the second gear and the first gear to rotate. During this process, the second gear drives the second rotating shaft to rotate 180°, and the first gear drives the first rotating shaft to rotate 90°. At this time, the sealing plate and the sealing frame are in close contact, thereby blocking the exhaust vent.

[0019] At this time, the fan unit starts to work. The fan unit draws air from inside the car through the sealing plate. The air inside the car is heated by the heat exchange pipe and then enters the car to circulate with the air inside the car, thereby improving the heating effect and the temperature inside the car. This setting can assist the heating system of electric vehicles in winter when the outside temperature is low, optimize the temperature inside the car, and effectively reduce the energy loss of the electric vehicle heating system.

[0020] Step 3: Post-maintenance: After prolonged use, the filter screen installed at the opening of the circulation shell needs to be replaced and maintained in a timely manner to ensure the stable operation of the equipment. During the maintenance process, a filter screen with a drying structure can be installed as needed to ensure the dryness of the air during the exchange with the air inside the vehicle.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, the temperature control mechanism can utilize the cold air from the car's air conditioning system and the low-pressure air conditioning pipe to cool the antifreeze flowing through the heat exchange pipe, thereby further improving the cooling effect of the car's motor and effectively enhancing the overall performance of the car in extreme environments. Furthermore, when the external temperature is low, the heat of the antifreeze flowing through the heat exchange pipe can be utilized to assist the electric vehicle's heating system, optimize the interior temperature, and effectively reduce the energy loss of the electric vehicle's heating system.

[0023] 2. In this invention, the system enhances the stability of coolant circulation through the optimized layout of water pipes. At the same time, through the ingenious design of electric push rods and gears, it realizes intelligent adjustment of air direction and flow. In low-temperature winter environments, the system can assist in vehicle heating, reduce energy loss, and improve passenger comfort. This multi-mode temperature control strategy not only improves energy efficiency but also enhances the vehicle's adaptability to different environmental conditions.

[0024] 3. In this invention, the intelligent temperature control system also takes into account the convenience of later maintenance. Through the design of the filter screen that is easy to replace and maintain, the reliability of the system's long-term stable operation is ensured. At the same time, the sealing design of the rubber ring ensures the sealing effect between the air conditioner's low-pressure pipe and the circulation shell, preventing air leakage and further improving the system's sealing performance and durability. This easy-to-maintain and highly reliable design greatly reduces the maintenance cost during long-term use. Attached Figure Description

[0041] A car motor cooling device with an integrated intelligent temperature control system and its usage method include a radiator 1, a fan 2, an expansion tank 3, an electric water pump 4, and water pipes 5. The fan 2 is installed on one side of the radiator 1. The upper end of one side of the radiator 1 is connected to the expansion tank 3 via water pipes 5. The lower end of one side of the radiator 1 is connected to the electric water pump 4 via water pipes 5. The electric water pump 4 is connected to the internal heat dissipation channel of a drive motor 6 via water pipes 5. A temperature control mechanism 8 is provided outside the water pipes 5 connecting the drive motor 6 and the radiator 1. An air conditioning low-pressure pipe 7 is installed on the inner side of the upper end of the temperature control mechanism 8. The temperature control mechanism 8 includes a circulation housing 81. A fan unit 82 is installed on the inner side of one end of the circulation housing 81, and a sealing plate 811 is installed on the inner side of the other end of the circulation housing 81.

Guide rods 86 are installed on both sides of the drive mechanism 85. A protective shell 84 is installed on the outside of the drive mechanism 85. A sealing frame 810 is installed on one side of the lower end of the sealing plate 811. An exhaust port 89 is opened on one side of the sealing frame 810. A rubber ring 88 is installed on the lower side of one end of the circulation shell 81. A heat exchange tube 87 is installed on the lower side of the rubber ring 88.

[0042] As a further implementation of this solution, the drive mechanism 85 includes a fixed base 851. An electric push rod 852 is fixedly connected to the inner side of the fixed base 851. A vertical plate 853 is fixedly connected to the moving end of the electric push rod 852. A first toothed plate 854 is fixedly connected to the upper end of the vertical plate 853, and a second toothed plate 855 is fixedly connected to the lower end of the vertical plate 853. Positioning holes 856 are provided inside both the first toothed plate 854 and the second toothed plate 855. The first toothed plate 854 and the second toothed plate 855 are parallel to each other, and the included angle between the first toothed plate 854 and the vertical plate 853 is 90°. The upper end of the first toothed plate 854 meshes with a second gear 815, and the lower end of the second toothed plate 855 meshes with a first gear 813. Both the 54 and the second toothed plate 855 are slidably connected to the guide rod 86 through the internal positioning hole 856. There are two fixed seats 851. The fixed seats 851 are fixedly connected to the baffle 83 by bolts. The fixed seats 851 are fixedly connected to the fixed end of the electric push rod 852. The included angle between the electric push rod 852 and the vertical plate 853 is 90°. With the above settings, the angle of the fan unit 82 and the sealing plate 811 can be adjusted during the overall operation of the device. Controlling the direction of the fan unit 82 can control the direction of the air blowing. By controlling the direction of the sealing plate 811, the opening and closing of one end of the circulation shell 81 and the exhaust port 89 can be realized, thereby changing the direction of the air.

[0043] As a further implementation of this solution, the heat exchange tube 87 includes an aluminum tube 871. Connecting flanges 873 are welded and fixed to the outer sides of both ends of the aluminum tube 871. Heat dissipation fins 872 are welded and fixed to the outer side of the middle of the aluminum tube 871. The connecting flanges 873 are welded and fixed to the circulation shell 81. Several heat dissipation fins 872 are provided. The heat dissipation fins 872 are arranged in a ring and are located inside the circulation shell 81. The aluminum tube 871 is connected to the water pipe 5. Through the above arrangement, heat exchange can be performed on the antifreeze flowing inside the heat exchange tube 87 located inside the circulation shell 81, so as to utilize the heat exchange according to different needs.

[0044] As a further implementation of this solution, multiple water pipes 5 are provided. The water pipe 5 connecting the radiator 1 and the electric water pump 4 is connected to the water inlet of the electric water pump 4. The water pipe 5 connecting the electric water pump 4 and the drive motor 6 is connected to the water inlet of the electric water pump 4. The expansion tank 3 is connected to the upper and lower ends of one side of the radiator 1 through two water pipes 5 respectively. Through the above settings, the overall stability of the integrated intelligent temperature control system can be further improved.

[0045] As a further implementation of this solution, the circulating housing 81 is U-shaped, and the circulating housing 81 and the protective housing 84 are fixedly connected by rivets. There are two baffles 83, the lower end of which is semi-circular. The baffles 83 are parallel to each other and are fixedly connected to the protective housing 84 by rivets. Through the above arrangement, the overall structural stability of the circulating housing 81 can be further improved, while the other end of the protective housing 84 can be sealed, and the protective housing 84 can be positioned as a whole.

[0046] As a further implementation of this solution, the openings on both sides of the upper end of the circulation housing 81 are connected to the interior of the car body. The interior of the circulation housing 81 is connected to the air conditioning low-pressure pipe 7 through rubber rings 88. There are two rubber rings 88, and the vertical cross section of the rubber rings 88 is set in the shape of "I". Through the above setting, the air conditioning low-pressure pipe 7 can be stably limited, and the sealing effect of the connection between the air conditioning low-pressure pipe 7 and the circulation housing 81 can be guaranteed.

[0047] The process includes the following steps: Step 1: System operation, optimizing heat dissipation through fan unit 82 in conjunction with air conditioning low-pressure pipe 7 and the in-vehicle environment: During this process, fan unit 82 draws air with a lower temperature than the outside from the in-vehicle air conditioning environment. This air is further cooled through air conditioning low-pressure pipe 7 and then exchanges heat with heat exchange pipe 87 to cool the coolant flowing through heat exchange pipe 87, further improving the heat dissipation effect of the vehicle drive motor 6, so as to ensure that the vehicle drive motor 6 can operate more stably. During the process, the cooling air is directly discharged to the outside of the vehicle through exhaust port 89, and fan unit 82 only works after the in-vehicle air conditioning is running.

[0048] Step II: Optimize the in-vehicle environment through water pipe 4: Electric push rod 852 drives vertical plate 853 to move. During the movement of vertical plate 853, the first toothed plate 854 and the second toothed plate 855 move synchronously, thereby driving the second gear 815 and the first gear 813 to rotate. During this process, the second gear 815 drives the second rotating shaft 814 to rotate 180°, and the first gear 813 drives the first rotating shaft 812 to rotate 90 degrees. At this time, the sealing plate 811 is in close contact with the sealing frame 810, thereby sealing the exhaust vent 89.

[0049] At this time, the fan unit 82 starts to work. The fan unit 82 draws air from the vehicle through the sealing plate 811. The air inside the vehicle is heated by the heat exchange pipe 87 and then enters the vehicle to circulate with the air inside the vehicle, thereby improving the heating effect and the temperature inside the vehicle. This setting can assist the heating system of electric vehicles in winter when the outside temperature is low, optimize the temperature inside the vehicle, and effectively reduce the energy loss of the electric vehicle heating system.

[0050] Step III: Post-maintenance: After prolonged use, the filter screen installed at the opening of the circulation housing 81 needs to be replaced and maintained in a timely manner to ensure the stable operation of the equipment. During the maintenance process, a filter screen with a drying structure can be installed as needed to ensure the dryness of the air during the exchange with the air inside the vehicle.
