[0022] The specific embodiments of the utility model are described below in combination with the drawings. Specific embodiment one

[0025] The surface of the box 1 is provided with a compressor 3, which provides power, sucks in outside air and compresses it into high-temperature and high-pressure gas to provide the necessary energy for the heat management system. The surface of the compressor 3 is provided with a flow guide pipe 4, which connects the compressor 3 and the first connecting pipe 5 and the second connecting pipe 6, guides the compressed gas to the condenser 7 or the evaporator 9. The surface of the flow guide pipe 4 is respectively communicated with the first connecting pipe 5 and the second connecting pipe 6. The first connecting pipe 5 guides the gas in the flow guide pipe 4 to the condenser 7. The second connecting pipe 6 guides the gas in the flow guide pipe 4 to the evaporator 9. The end of the first connecting pipe 5 is provided with the condenser 7. The condenser 7 exchanges heat with the surrounding environment, and the gas is liquid in the condenser 7 and releases heat. The surface of the condenser 7 is provided with a first input pipe 8. The end of the first input pipe 8 is provided with a first heat conduction pipe 12. The released heat enters the first heat conduction pipe 12 through the first input pipe 8 and is transmitted to the battery body 20 through the first heat conduction pipe 12, realizing the warming process of the battery body 20. The end of the first heat conduction pipe 12 is provided with a first output pipe 13. When the temperature of the battery body 20 gradually rises to the set temperature and more heat is no longer needed, the condenser 7 is still working, and the first heat conduction pipe 12 still has heat transmitted. This part of the excess heat needs to be discharged from the system through the exhaust pipe 11 and the first output pipe 13 to prevent the temperature of the battery body 20 from being too high.

[0026] The end of the second connecting pipe 6 is provided with an evaporator 9, which makes the gas expand rapidly and absorb heat to realize self-cooling. The condenser 7 and the evaporator 9 are respectively arranged on the two sides of the box body 1. The surface of the evaporator 9 is provided with a second input pipe 10. The end of the second input pipe 10 is provided with a second heat conducting pipe 14. The cooled gas passes through the second heat conducting pipe 14 and transfers low temperature to the battery body 20 to quickly take away the heat generated by the battery body 20 to realize the cooling operation of the battery. The shapes of the first heat conducting pipe 12 and the second heat conducting pipe 14 are both S-shaped. The first heat conducting pipe 12 and the second heat conducting pipe 14 are staggered. The heat exchange area is increased by this arrangement. The surfaces of the first heat conducting pipe 12 and the second heat conducting pipe 14 are both provided with a fixing ring 17. The first heat conducting pipe 12 and the second heat conducting pipe 14 are connected with the support plate 2 through the fixing ring 17. The fixing ring 17 is used to fix the first heat conducting pipe 12 and the second heat conducting pipe 14 to ensure their stable positions on the support plate 2. The end of the second heat conducting pipe 14 is provided with a second output pipe 18. The second output pipe 18 leads out the cooling medium in the second heat conducting pipe 14. The side of the box body 1 is provided with an exhaust pipe 11.

The ends of the first output pipe 13 and the second output pipe 18 are respectively connected with the exhaust pipe 11. The surfaces of the flow guide pipe 4, the first connecting pipe 5 and the second connecting pipe 6 are provided with a first three-way valve 15. The first three-way valve 15 controls the flow direction of the gas in the flow guide pipe 4 and selectively leads it to the condenser 7 or the evaporator 9. The surfaces of the exhaust pipe 11, the first output pipe 13 and the second output pipe 18 are provided with a second three-way valve 16. The second three-way valve 16 respectively controls the flow direction of the medium in the first output pipe 13 and the second output pipe 18 and the exhaust pipe 11.

[0027] When the temperature sensor 21 detects that the temperature of the battery body 20 is high, the system quickly opens the compressor 3, which sucks in and compresses the outside air to form high-temperature and high-pressure gas, which flows into the condenser 7 to exchange heat with the surrounding environment. The gas is liquid in the condenser 7 and releases a large amount of heat, which is transferred to the battery body 20 through the first heat-conducting pipe 12, realizing the warming process of the battery body 20 and promoting the rapid rise of the temperature of the battery body 20 to the appropriate working interval, ensuring the activity and performance of the battery body 20 are not affected by low temperature. If the battery body 20 temperature reaches the set value, the condenser 7 is still working to generate excess heat, which can be discharged from the system through the first output pipe 13 and the exhaust pipe 11; when the temperature sensor 21 detects that the temperature of the battery body 20 is high, the system switches through the first three-way valve 15, so that the compressed gas enters the evaporator 9 through the second connecting pipe 6. In the evaporator 9, the gas expands rapidly and absorbs the heat of the surrounding environment, thereby realizing its cooling. The cooled gas passes through the second heat-conducting pipe 14 and transfers low temperature to the battery body 20, quickly taking away the heat generated by the battery body 20, realizing the cooling operation of the battery body 20. The cooling medium is finally discharged through the second output pipe 18, and the exhaust pipe 11 can collect the heat and medium in the first output pipe 13 and the second output pipe 18 respectively through the second three-way valve 16 and discharge the system. The whole temperature control process is intelligent, efficient and automatic, which provides reliable guarantee for the stable operation of the battery body 20. Specific embodiment two:

[0029] A high-efficiency thermal management lithium battery temperature control module based on the basic structure in specific embodiment one further discloses the following content. Heat-conducting sheets can be innovatively arranged between the support plate 2 and the first heat-conducting pipe 12 and the second heat-conducting pipe 14, realizing rapid heat transfer and ensuring that the first heat-conducting pipe 12 and the second heat-conducting pipe 14 can efficiently transfer heat to the battery body 20 on the support plate 2, significantly improving the efficiency and fluency of heat transfer, so that the whole temperature control module can perform more outstanding performance in the warming or cooling process.

[0030] In summary:

[0031] 1. The system employs a compressor 3, a condenser 7, an evaporator 9, a first heat pipe 12, and a second heat pipe 14. When the temperature sensor 21 detects a high temperature in the battery body 20, the system quickly activates the compressor 3. The compressor 3 draws in outside air and compresses it to form a high-temperature, high-pressure gas. This gas flows into the condenser 7, where it exchanges heat with the surrounding environment. The gas becomes liquid in the condenser 7 and releases a large amount of heat. This heat is transferred to the battery body 20 through the first heat pipe 12, thus raising the temperature of the battery body 20 rapidly to a suitable operating range and ensuring the activity of the battery body 20. The performance is unaffected by low temperatures. On the contrary, when the temperature of the battery body 20 is detected to be high, the system will switch the first three-way valve 15 to guide the compressed gas into the evaporator 9. In the evaporator 9, the gas expands rapidly and absorbs heat from the surrounding environment, thereby achieving its own cooling. The cooled gas passes through the second heat pipe 14 and transfers the low temperature to the battery body 20, quickly removing the heat generated by the battery body 20 and achieving the cooling operation of the battery body 20. This effectively avoids the performance degradation or safety hazards of the battery body 20 caused by high temperature. The entire temperature control process is intelligent, efficient and automated, providing a reliable guarantee for the stable operation of the battery body 20.
