Description

Technical Field

[0001] This invention relates to a gas-heat channel control device, and more particularly to a gas-heat channel control device for new energy vehicles based on aluminum conduction pretreatment, belonging to the field of new energy vehicle technology. Background Technology

[0002] New energy vehicles use electric motors to provide power, which are much quieter than internal combustion engines, making the riding environment more comfortable, and the start-up is very smooth. They also produce less pollution, which is beneficial to environmental protection.

[0003] However, new energy vehicles require significantly more charging time compared to gasoline vehicles. As we all know, mobile phones generate a lot of heat during charging, and charging new energy vehicles will inevitably release a large amount of heat. If the heat cannot be dissipated in time, it will accelerate the aging of the wires and significantly reduce the battery's lifespan, thus severely shortening the vehicle's lifespan. This will require substantial funds for repairs later on. Existing heat dissipation devices only dissipate heat from the battery pack through aluminum conduction, which has low heat dissipation efficiency.

[0004] In addition, batteries degrade quickly, especially in winter, when their activity is severely reduced. The car's range will be greatly reduced due to the lower temperature, and frequent charging will shorten the battery's lifespan.

[0005] Therefore, it is urgent to improve the control device of the air-heat channel in new energy vehicles in order to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a new energy vehicle air-heat channel control device based on aluminum conduction pretreatment. The lower side of the semiconductor cooling chip abuts against the battery pack, which increases the contact area and absorbs the heat generated by the battery pack. The heat is directly conducted to the interior of the aluminum conductor through heat conduction. Under the action of the compressor, the heat is drawn into the condenser for condensation. Then, under the action of the air pump, the heat is discharged back into the interior of the aluminum conductor, forming a cold cycle. When the temperature drops, the heater heats the cold airflow, forming a hot cycle, which improves the heat dissipation efficiency and service life of the battery pack.

[0007] To achieve the above objectives, the main technical solution adopted by the present invention includes: a new energy vehicle air-heat channel control device based on aluminum conduction pretreatment, comprising an aluminum conduction component fixed on a battery pack, one end of the aluminum conduction component being connected to a heat exchanger via a vent pipe, and the heat exchanger being provided with a first air inlet, a first air outlet, a second air inlet, and a second air outlet. The first exhaust port of the exchanger is connected in sequence to a compressor and a condenser, and then connected to the second air inlet of the exchanger. The second exhaust port of the exchanger is connected to a heater through a vent pipe. An air pump is connected between the heater and the aluminum conductive component. The aluminum conductive component is fixed to the upper side of the battery pack. The heat generated by the battery pack is conducted to the outside of the battery pack through the aluminum conductive component, thus achieving the purpose of heat dissipation. At the same time, the interior of the aluminum conductive component is connected to a heat exchanger through a vent pipe. The heat generated by the battery pack is directly conducted to the interior of the aluminum conductive component, causing the internal temperature of the aluminum conductive component to rise. Under the action of the compressor, the hot air inside the aluminum conductive component is extracted through the heat exchanger and condensed in the condenser, that is, the temperature of the hot air is reduced. Then, under the action of the air pump, it is discharged back into the interior of the aluminum conductive component through the heat exchanger. This forms a cycle, extracting the hot air from the interior of the aluminum conductive component, condensing it, and then circulating it back into the interior of the aluminum conductive component. This can significantly reduce the temperature of the aluminum conductive component, thereby reducing the temperature of the battery pack and extending the service life of the battery pack. The bottom side of the aluminum conductive component has several evenly distributed cooling chip slots. A semiconductor cooling chip is fixedly installed inside the cooling chip slot. The semiconductor cooling chip includes a cooling chip heat absorption surface and a cooling chip heat dissipation surface. The cooling chip heat absorption surface abuts against the upper side of the battery pack, and the cooling chip heat dissipation surface abuts against the inner side of the cooling chip slot.

[0008] The thermoelectric cooler is fixed on the cooler slot of the aluminum conductor. The lower side of the thermoelectric cooler abuts against the battery pack, which increases the contact area with the battery pack and can fully absorb the heat generated by the battery pack, thereby improving the heat dissipation efficiency of the aluminum conductor. After the heat-absorbing surface of the thermoelectric cooler absorbs the heat generated by the battery pack, the heat-dissipating surface of the thermoelectric cooler transfers the heat to the interior of the aluminum conductor through heat conduction, further improving the heat dissipation efficiency of the aluminum conductor for the battery pack. In addition, when the temperature is cold, the activity of the battery will be greatly reduced due to the low temperature. The reduced activity of the battery will seriously affect the car's range, and the user will need to charge the battery frequently, thus seriously affecting the battery's lifespan. When the temperature of the battery pack drops, the heat exchanger 3 directly discharges the cold air into the interior of the heater. The heater heats the cold air, and the heated air enters the interior of the aluminum conductor through the air pump, causing the temperature of the aluminum conductor to rise. This heats the battery pack, improves its activity, and helps to extend the vehicle's range.

[0009] Preferably, the aluminum conductive element has a U-shaped structure, and the lower side of the aluminum conductive element abuts against the upper side of the battery pack; The aluminum conductive component is provided with a conductive component exhaust port and a conductive component intake port, and the heat exchanger is connected to the aluminum conductive component through the conductive component exhaust port; The air pump is connected to the interior of the aluminum conductor through the air intake port of the conductor.

[0010] Preferably, the length of the thermoelectric cooler is greater than the width of the thermoelectric cooler slot, the thermoelectric cooler extends to the outside of the thermoelectric cooler slot, and a plurality of evenly distributed heat sinks are provided on the upper side of the thermoelectric cooler protruding from the thermoelectric cooler slot.

[0011] Preferably, the aluminum conductive component is provided with a plurality of evenly distributed conductive component fixing plates, the conductive component fixing plates are provided with conductive component mounting holes, the upper side of the battery pack is provided with blind holes, and the conductive component mounting holes are provided with fastening screws inside the conductive component mounting holes. The fastening screws pass through the conductive component mounting holes and are connected to the blind holes by threaded engagement.

[0012] Preferably, the exhaust port of the conductive element is connected to the first air inlet of the exchanger through the vent pipe, the input end of the compressor is connected to the first exhaust port of the exchanger through the vent pipe, the output end of the compressor is connected to the input end of the condenser through the vent pipe, and the output end of the condenser is connected to the second air inlet of the exchanger through the vent pipe.

[0013] Preferably, the second exhaust port of the exchanger is connected to the heater via the vent pipe and the input end of the heater, the output end of the heater is connected to the input end of the air pump via the vent pipe, and the output end of the air pump is connected to the air intake port of the conductive element via the vent pipe.

[0014] Preferably, a controller is provided on one side of the heat exchanger. The compressor, condenser, heater, air pump, and thermoelectric cooler are all electrically connected to the controller via wires. The controller is provided on the entire device, and the compressor, condenser, heater, and air pump are all electrically connected to the controller. Automated control improves heat dissipation efficiency. Several thermoelectric coolers are arranged in parallel on the controller and connected in parallel. Multiple thermoelectric coolers do not affect each other, improving the safety of use.

[0015] Preferably, the plurality of the semiconductor cooling chips are arranged in parallel on the controller.

[0016] Preferably, the controller is connected to a wireless transmission module, and the wireless transmission module establishes a communication connection with the controller.

[0017] Preferably, a temperature sensor is fixedly installed on the lower side of the aluminum conductive component. The temperature sensor is located between the aluminum conductive component and the battery pack, and the temperature sensor establishes a communication connection with the controller. In addition, the temperature sensor is fixedly installed on the lower side of the aluminum conductive component, located between the aluminum conductive component and the battery pack, and the temperature sensor establishes a communication connection with the controller. The temperature sensor directly transmits temperature information to the controller, which can be directly observed via a mobile phone or other means, facilitating timely temperature adjustment and improving ease of use.

[0018] The present invention has at least the following beneficial effects: 1. The lower side of the semiconductor cooling chip abuts against the battery pack, which increases the contact area and absorbs the heat generated by the battery pack. The heat is then directly conducted to the interior of the aluminum conductive component through heat conduction. Under the action of the compressor, the heat is drawn into the condenser for condensation. Then, under the action of the air pump, the heat is discharged back into the interior of the aluminum conductive component, thus forming a cycle. This significantly reduces the temperature of the battery pack and improves the heat dissipation efficiency and service life of the battery pack.

[0019] 2. In addition, when the temperature is cold, the activity of the battery will be greatly reduced due to the low temperature. When the temperature of the battery pack drops, the heat exchanger directly discharges the cold air into the interior of the heater. The heater heats the cold air, and the heated air enters the interior of the aluminum conductor through the air pump, causing the temperature of the aluminum conductor to rise. This can then heat the battery pack, improve the activity of the battery pack, and help improve the vehicle's range. Attached Figure Description

Detailed Implementation

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-7 As shown, the new energy vehicle air-heat channel control device based on aluminum conduction pretreatment provided in this embodiment includes an aluminum conduction component 1 fixed on the battery pack 11. One end of the aluminum conduction component 1 is connected to a heat exchanger 3 through a vent pipe 10. The heat exchanger 3 is provided with a first air inlet 301, a first air outlet 302, a second air inlet 303, and a second air outlet 304. A compressor 4 and a condenser 5 are sequentially connected to the first exhaust port 302 of the exchanger, and then connected to the second intake port 303 of the exchanger. The exhaust port 101 of the conductive element is connected to the first intake port 301 of the exchanger through a vent pipe 10. The input end of the compressor 4 is connected to the first exhaust port 302 of the exchanger through a vent pipe 10. The output end of the compressor 4 is connected to the input end of the condenser 5 through a vent pipe 10. The output end of the condenser 5 is connected to the second intake port 303 of the exchanger through a vent pipe 10. The second exhaust port 304 of the exchanger is connected to a heater 6 through a vent pipe 10. An air pump 7 is connected between the heater 6 and the aluminum conductive element 1. The second exhaust port 304 of the exchanger is connected to the input end of the heater 6 through a vent pipe 10. The output end of the heater 6 is connected to the input end of the air pump 7 through a vent pipe 10. The output end of the air pump 7 is connected to the intake port 102 of the conductive element through a vent pipe 10. The aluminum conductive component 1 is fixed to the upper side of the battery pack 11. The heat generated by the battery pack 11 is conducted to the outside of the battery pack 11 through the aluminum conductive component 1, thereby achieving the purpose of heat dissipation for the battery pack 11. At the same time, the interior of the aluminum conductive component 1 is connected to the heat exchanger 3 through the vent pipe 10. The heat generated by the battery pack 11 is directly conducted to the interior of the aluminum conductive component 1 through heat conduction, causing the temperature inside the aluminum conductive component 1 to rise. Under the action of the compressor 4, the hot airflow inside the aluminum conductive component 1 is extracted through the heat exchanger 3 and condensed in the condenser 5, that is, the temperature of the hot airflow is reduced. Then, under the action of the air pump 7, it is discharged back into the interior of the aluminum conductive component 1 through the heat exchanger 3. Thus, a cycle is formed, the hot airflow inside the aluminum conductive component 1 is extracted, condensed, and then circulated back into the interior of the aluminum conductive component 1, thereby significantly reducing the temperature of the aluminum conductive component 1, thereby reducing the temperature of the battery pack 11 and improving the service life of the battery pack 11. The bottom side of the aluminum conductive component 1 is provided with several uniformly distributed cooling chip slots 103. A semiconductor cooling chip 2 is fixedly installed inside the cooling chip slot 103. The semiconductor cooling chip 2 includes a cooling chip heat absorption surface 201 and a cooling chip heat dissipation surface 202. The cooling chip heat absorption surface 201 abuts against the upper side of the battery pack 11, and the cooling chip heat dissipation surface 202 abuts against the inner side of the cooling chip slot 103. The semiconductor cooling chip 2 is fixed on the cooling chip groove 103 of the aluminum conductive component 1. The lower side of the semiconductor cooling chip 2 abuts against the battery pack 11, which increases the contact area with the battery pack 11 and can fully absorb the heat generated by the battery pack 11, thereby improving the heat dissipation efficiency of the aluminum conductive component 1. After the heat absorption surface 201 of the semiconductor cooling chip 2 absorbs the heat generated by the battery pack 11, the heat dissipation surface 202 of the cooling chip transfers the heat to the interior of the aluminum conductive component 1 through thermal conduction, further improving the heat dissipation efficiency of the aluminum conductive component 1 for the battery pack 11. In addition, when the temperature is cold, the activity of the battery will be greatly reduced due to the low temperature. The reduced activity of the battery will seriously affect the car's range, and the user will need to charge the battery frequently, thus seriously affecting the battery's lifespan. When the temperature of the battery pack 11 drops, the heat exchanger 3 directly discharges the cold air into the interior of the heater 6. The heater 6 heats the cold air, and the heated air enters the interior of the aluminum conductor 1 through the air pump 7, causing the temperature of the aluminum conductor 1 to rise, which in turn heats the battery pack 11, improves the activity of the battery pack 11, and facilitates the improvement of the vehicle's range.

[0024] Furthermore, such as Figure 1 and Figure 3As shown, the aluminum conductive component 1 has a U-shaped structure, and the lower side of the aluminum conductive component 1 abuts against the upper side of the battery pack 11. The aluminum conductive component 1 is provided with a conductive component exhaust port 101 and a conductive component intake port 102. The heat exchanger 3 is connected to the aluminum conductive component 1 through the conductive component exhaust port 101, and the air pump 7 is connected to the interior of the aluminum conductive component 1 through the conductive component intake port 102. The heat exchanger 3 is connected to the exhaust port 101 of the aluminum conductive component 1, and the air pump 7 is connected to the intake port 102 of the aluminum conductive component 1. Therefore, a cycle can be formed to dissipate the heat inside the aluminum conductive component 1 and improve the heat dissipation efficiency of the aluminum conductive component 1.

[0025] Furthermore, such as Figure 1 and Figure 5 As shown, the length of the thermoelectric cooler 2 is greater than the width of the thermoelectric cooler slot 103. The thermoelectric cooler 2 extends to the outside of the thermoelectric cooler slot 103. Several evenly distributed heat dissipation plates 12 are provided on the upper side of the thermoelectric cooler 2 protruding from the thermoelectric cooler slot 103. A part of the thermoelectric cooler 2 is located on the outside of the thermoelectric cooler slot 103. Through the heat dissipation plates 12 on the thermoelectric cooler 2, some of the heat can be dissipated into the air. The heat dissipated by the thermoelectric cooler 2 is carried away by the airflow generated during the driving process, which further improves the heat dissipation efficiency. Meanwhile, the aluminum conductive component 1 is provided with several evenly distributed conductive component fixing plates 8. The conductive component fixing plates 8 have conductive component mounting holes 801. A blind hole is provided on the upper side of the battery pack 11. A fastening screw 9 is installed inside the conductive component mounting hole 801, passing through the conductive component mounting hole 801 and connecting with the blind hole via a threaded connection. By using the fastening screw 9 to pass through the conductive component fixing plates 8, the aluminum conductive component 1 is fixed to the upper side of the battery pack 11. This effectively prevents the aluminum conductive component 1 from shaking during vehicle operation, improving the stability of the aluminum conductive component 1. At the same time, fixing the aluminum conductive component 1 to the battery pack 11 via the conductive component fixing plates 8 also secures the battery pack 11, further improving its stability. Furthermore, such as Figure 1 , Figure 2 as well as Figure 7 As shown, a controller 14 is provided on one side of the heat exchanger 3. The compressor 4, condenser 5, heater 6, air pump 7 and thermoelectric cooler 2 are all electrically connected to the controller 14 via wires 15. The controller 14 is provided on the entire device, and the compressor 4, condenser 5, heater 6 and air pump 7 are all electrically connected to the controller 14. Automated control improves the efficiency of heat dissipation. Several thermoelectric coolers 2 are arranged in parallel on the controller 14 and connected in parallel to 14. Multiple thermoelectric coolers 2 do not affect each other, improving the safety of use. Meanwhile, the controller 14 is connected to a wireless transmission module 13, which establishes a communication connection with the controller 14. The wireless transmission module 13 can establish a communication connection with mobile phones, cars, etc., making operation more convenient and improving ease of use. In addition, a temperature sensor 16 is fixedly installed on the lower side of the aluminum conductive component 1. The temperature sensor 16 is located between the aluminum conductive component 1 and the battery pack 11, and the temperature sensor 16 establishes a communication connection with the controller 14. The temperature sensor 16 directly transmits the temperature information to the controller 14, which can be directly observed through a mobile phone or other means, making it convenient to adjust the temperature in a timely manner and improving the ease of use.
