[0013] As further optimized content of the present invention, the following steps are included: Step I: Temperature regulation when the temperature of the antifreeze liquid inside the aluminum straight tube is high: when the temperature of the antifreeze liquid transported inside the aluminum straight tube is high, the antifreeze liquid is used as a heat exchange carrier to exchange heat with the low-temperature air conditioning refrigerant through an electronic expansion valve, thereby realizing heat conversion and transfer, and completing the temperature regulation of the battery pack, wherein the mass component ratio of the antifreeze liquid is: 48% water + 50% ethanol + 2% corrosion inhibitor, antifoaming agent, and the low freezing point of ethanol is used to reduce the freezing point of the solution. According to the different media, the liquid temperature regulating device is divided into two working areas: refrigerant circulation and antifreeze liquid circulation. The heat exchange processes of the two cycles are concentrated in the plate heat exchanger. The low-temperature refrigerant generated by the operation of the air conditioning system enters the plate heat exchanger. At the same time, under the action of the circulating water pump, the antifreeze liquid also enters the plate heat exchanger. The two circulate in their own independent channels, and through the special structure stacked on each other, the contact conduction function is used to realize the temperature transmission and cool the battery pack; The stacked structure of the plate heat exchanger is: multiple thin plates are stacked on each other, and many narrow and deep channels are formed between these thin plates. Two fluids of different temperatures flow in adjacent channels respectively. Moreover, the channels are narrow, and turbulence is easily generated when the fluid flows in the channels, which enhances the heat transfer between the fluid and the wall surface. The large number of thin plates greatly increases the total heat transfer area of the heat exchanger, thereby improving the heat exchange efficiency. Step II: Temperature regulation when the temperature of the antifreeze inside the aluminum straight tube is low: When the temperature of the antifreeze transported inside the aluminum straight tube is low, the antifreeze is heated by the electric heating plate to achieve the heating of the battery pack. During the heating process, the antifreeze is used as a heat exchange carrier to exchange heat with the electric heating plate, thereby achieving heat conversion and transfer to complete the temperature regulation of the battery pack. The antifreeze transported inside the aluminum straight tube is heated by the spiral setting of the electric heating wire inside the electric heating plate, and the electric heating wire is set on the outside of the aluminum straight tube and is tightly attached to the aluminum straight tube. Then, at low temperatures, the viscosity of the electrolyte is reduced, the ion conductivity is increased, and the output power of the battery is increased. At the same time, the reaction rate can be accelerated, the charging and discharging efficiency can be improved, and the growth of lithium dendrites can be inhibited, extending the battery life, so that the battery can store more electrical energy in the same volume to reduce side reactions and reduce energy loss.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the high-efficiency battery heat exchange adjustment device needs to be repaired and replaced in the later stage, the connection between the high-efficiency battery heat exchange adjustment device and the external water pipe can be completed by rotating the first screw, which is more convenient and can effectively improve the efficiency of the later maintenance and replacement of the high-efficiency battery heat exchange adjustment device; 2. In the present invention, the high-efficiency battery heat exchange regulating device realizes precise control of the battery temperature through the coordinated work of the electronic expansion valve and the plate heat exchanger. In a high-temperature environment, the refrigerant and the antifreeze are used to exchange heat inside the plate heat exchanger, which effectively reduces the battery temperature and prevents overheating damage. In low-temperature conditions, the auxiliary heating function of the electric heating plate can increase the temperature of the antifreeze to ensure the temperature required for the normal operation of the battery. This dual-mode regulation mechanism not only improves the thermal management efficiency of the battery, but also significantly enhances the stability and service life of the battery system. 3. In the present invention, the modular design and simple installation process of the device bring convenience to on-site installation and maintenance. At the same time, the sealing performance of the device is enhanced by the cooperation of the adapter groove and the sealing gasket, ensuring the reliability of long-term operation. In addition, the heat exchange intensity can be automatically adjusted according to the actual heat load of the battery, further improving energy efficiency, reducing energy consumption, and showing excellent energy-saving effects.

According to the different media, the liquid temperature regulating device is divided into two working areas: refrigerant circulation and antifreeze liquid circulation. The heat exchange processes of the two cycles are concentrated in the plate heat exchanger 5. The low-temperature refrigerant generated by the operation of the air-conditioning system enters the plate heat exchanger 5. At the same time, under the action of the circulating water pump, the antifreeze liquid also enters the plate heat exchanger 5. The two circulate in their own independent channels, and through the special structure stacked on each other, the contact conduction function is used to realize the temperature transmission and cool the battery pack; The laminated structure of the plate heat exchanger 5 is: multiple thin plates are stacked together, and many narrow and deep channels are formed between these thin plates.

Two fluids of different temperatures flow in adjacent channels respectively. The channels are narrow, and turbulence is easily generated when the fluid flows in the channels, thereby enhancing heat transfer between the fluid and the wall surface. By utilizing a large number of thin plates, the total heat transfer area of the heat exchanger is greatly increased, thereby improving the heat exchange efficiency. Step II: Temperature regulation when the temperature of the antifreeze liquid inside the aluminum straight tube (6) is low: When the temperature of the antifreeze liquid transported inside the aluminum straight tube (6) is low, the antifreeze liquid is heated by the electric heating plate (42) to achieve the temperature increase of the battery pack. During the temperature increase process, the antifreeze liquid is used as a heat exchange carrier to exchange heat with the electric heating plate (42), thereby achieving heat conversion and transfer, and completing the temperature regulation of the battery pack. The electric heating wire spiral is arranged inside the electric heating plate (42), and the electric heating wire is arranged on the outside of the aluminum straight tube (6) and is tightly attached to the aluminum straight tube (6), so as to achieve the heating of the antifreeze liquid transported inside the aluminum straight tube (6), thereby reducing the viscosity of the electrolyte at low temperature, improving the ion conductivity, and thus improving the output power of the battery. At the same time, the reaction rate can be accelerated, the charging and discharging efficiency can be improved, and the growth of lithium dendrites can be inhibited, thereby extending the battery life, so that the battery can store more electrical energy in the same volume, thereby reducing side reactions and reducing energy loss.
