The battery cooling system operates in self-circulation mode, resulting in insufficient heat dissipation and triggering a battery high-temperature alarm, which poses a risk to battery life.

[0010] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0011] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0012] The following is combined Figures 1 to 7 This invention describes a new energy air conditioning system with an integrated battery water cooling system according to some embodiments of the present invention.

[0013] One embodiment of this utility model first proposes a new energy air conditioning system integrating a battery water cooling system, such as... Figure 1As shown, the new energy air conditioning system includes: a first flow channel module for plate heat exchange, a second flow channel module for plate heat exchange, and a battery radiator module, wherein, as... Figure 2 As shown, the first flow channel module of the heat exchanger includes a battery, a water pump, an expansion tank, two water valves on the heat exchanger side, and the first flow channel of the heat exchanger. Figure 3 As shown, the plate heat exchanger second flow channel module includes a first expansion valve, a plate heat exchanger second flow channel, a second expansion valve, an evaporator, a compressor, a condenser, and a fan, as follows. Figure 4 As shown, the battery radiator module includes the battery, the water pump, the expansion tank, two water valves on the battery radiator side, and the battery radiator. like Figure 1 As shown, the first end of the battery is connected to the first end of the water pump. The second end of the water pump, the expansion tank, the first ends of the two water valves on the heat exchanger side, and the first ends of the two water valves on the battery radiator side are connected in pairs. The second end of the battery, the second end of the first flow channel of the heat exchanger, and the second end of the battery radiator are connected in pairs. The second ends of the two water valves on the battery radiator side are connected to the first end of the battery radiator. The first ends of the first expansion valve, the first ends of the second expansion valve, and the first end of the condenser are connected in pairs. The second end of the first expansion valve is connected to the first end of the second flow channel of the heat exchanger. The second end of the second expansion valve is connected to the first end of the evaporator. The second ends of the second flow channel of the heat exchanger, the second end of the evaporator, and the first end of the compressor are connected in pairs. The second end of the compressor is connected to the second end of the condenser.

[0014] like Figure 1 As shown, the first flow channel of the plate heat exchanger is in contact with the second flow channel of the plate heat exchanger, and the fan is on the condenser side.

[0015] like Figure 5 As shown, when a signal indicating heat release from the battery is received and the ambient temperature is greater than or equal to a preset temperature, the two water valves on the heat exchanger side are opened, and the two water valves on the battery radiator side are closed, so that heat dissipation occurs through the first heat exchanger channel of the first heat exchanger module and the second heat exchanger channel of the second heat exchanger module. At this time, circulating water flows in the first heat exchanger channel module, and refrigerant flows in the second heat exchanger channel module.

[0016] like Figure 6As shown, when the battery releases heat signal and the ambient temperature is lower than the preset temperature, the two water valves on the heat exchanger side are closed, and the two water valves on the battery radiator side are opened to dissipate heat through the fan of the second flow channel module of the heat exchanger and the battery radiator module. At this time, the battery radiator module is filled with circulating water, while the refrigerant in the second flow channel module of the heat exchanger does not flow. Only the fan of the second flow channel module of the heat exchanger is working (because when the ambient temperature is lower than the preset temperature, for example, less than 5 degrees Celsius, the interior temperature is also low, and there is no need for cooling inside the vehicle. Therefore, the refrigerant in the second flow channel module of the heat exchanger does not flow, which means that there is no cooling inside the vehicle. Only the fan of the second flow channel module of the heat exchanger is working to dissipate heat from the battery radiator).

[0017] In the above embodiments, the two-way water valves on the heat exchanger side and the two-way water valves on the battery radiator side control the flow of fluid and determine the path of heat transfer. Specifically, the preset temperature can be 5 degrees Celsius. 1. When the ambient temperature is greater than or equal to 5 degrees Celsius and the battery needs heat dissipation, the two-way water valves on the heat exchanger side are opened, and the two-way water valves on the battery radiator side are closed. The water passage on the battery side is connected to the first flow channel of the heat exchanger, cutting off the heat dissipation path from the battery to the battery radiator. Heat is no longer dissipated by directly passing from the battery to the battery radiator. 2. When the ambient temperature is below 5 degrees Celsius and the battery needs heat dissipation, close the two water valves on the heat exchanger side and open the two water valves on the battery radiator side. This disconnects the water path on the battery side from the first flow channel of the heat exchanger, thus connecting the heat dissipation path from the battery to the battery radiator. Because when the ambient temperature is low, the heat exchanger relies on heat exchange with the environment for heat dissipation. At low temperatures, it is difficult to dissipate heat, and the heat dissipation efficiency of the heat exchanger will decrease significantly. Therefore, at this time, close the two water valves on the heat exchanger side, disconnect the water path on the battery side from the first flow channel of the heat exchanger, and open the two water valves on the battery radiator side to directly dissipate heat using the battery radiator, and enhance the heat dissipation effect with the assistance of a fan.

[0018] 1. When heat dissipation occurs through the first flow channel of the first flow channel module and the second flow channel of the second flow channel module, the working principle of the heat exchanger is utilized. Explain how heat dissipation is achieved based on the working principle of the heat exchanger: In general, batteries generate heat and require heat dissipation. The first and second flow channels of the plate heat exchanger refer to the two flow channels of the entire plate heat exchanger device. The plate heat exchanger is an inseparable whole. The working principle of the plate heat exchanger is as follows: The plate heat exchanger consists of a set of thin metal plates (usually made of materials with good thermal conductivity such as stainless steel). These metal plates have corrugated surfaces, and the plates are separated by sealing gaskets to form flow channels. These flow channels are divided into two groups. One group is used for circulating water (the circulating water path on the battery side, which refers to the circulating water flowing through the battery. Since both the first flow module and the battery heat sink module include the battery, the first flow module and the battery heat sink module both flow with circulating water). The other group is used for the refrigerant in the second flow channel module. Heat exchange occurs through the metal plates, transferring heat from one medium to another, thereby removing the heat from the battery.

[0019] Specifically, the process of heat exchange between metal plates, transferring heat from one medium to another, and thus removing heat from the battery, includes: (1) Battery-side circulating water circuit: When the battery needs to dissipate heat, the circulating water absorbs heat from the battery under the action of the water pump. The heat of the battery is absorbed by the circulating water in the water circuit. The circulating water with a higher temperature flowing out of the battery carries the heat generated by the battery into the first flow channel of the plate heat exchanger. Since the metal plate has good thermal conductivity, the heat of the circulating water will be conducted to the metal plate. It should be noted that the expansion tank is a key component of the circulating water system. Its function is to address the volume change of the circulating water during heating or cooling. Specifically, when the circulating water is heated, it expands, increasing its volume. If the water system is closed, the pressure will rise sharply, potentially damaging pipes or valves. Therefore, the expansion tank is connected to the water system. When the circulating water expands, the excess circulating water flows into the expansion tank for temporary storage. When the circulating water cools, it contracts, decreasing its volume. At this time, the circulating water temporarily stored in the expansion tank flows back into the water system to fill the gap and prevent water shortage. Water shortage will lead to decreased heat dissipation efficiency and may even cause components to burn out due to dry burning.

[0020] (2) Refrigerant side of the second flow channel module of the plate heat exchanger: Driven by the compressor, the low-temperature refrigerant enters the second flow channel of the plate heat exchanger and contacts the metal plate to absorb the heat conducted from the circulating water by the plate. Specifically, the refrigerant undergoes a cycle of compression-condensation-throttling-evaporation, involving a compressor, condenser, fan, expansion valves (including the first and second expansion valves), and evaporator. The compressor's role is to provide power to the refrigerant. Figure 5As shown, the low-temperature, low-pressure gaseous refrigerant from the evaporator (the evaporator converts the refrigerant from a liquid to a gaseous state, thus absorbing heat) is drawn into the compressor and mechanically compressed into a high-temperature, high-pressure gaseous refrigerant. The condenser cools and liquefies this high-temperature, high-pressure gaseous refrigerant, releasing heat. The first and second expansion valves both function to cool the condenser (the condenser converts the refrigerant from a gaseous state to a liquid state, thus releasing heat; the released heat is transferred to the condenser fins), and the fan blows low-temperature ambient air towards the condenser, carrying away the heat from the condenser fins. The medium-temperature, high-pressure liquid refrigerant (which can be efficiently condensed) is throttled and depressurized. Throttling controls the flow rate of the refrigerant into the next device to avoid refrigerant waste and affecting cooling efficiency. For the first expansion valve, this controls the flow rate of the refrigerant into the second channel of the plate heat exchanger. For the second expansion valve, this controls the flow rate of the refrigerant into the evaporator. Depressurization converts the medium-temperature, high-pressure liquid refrigerant into a low-temperature, low-pressure mist-like refrigerant (gas-liquid mixture) to lower the refrigerant temperature below that of the object that needs to absorb heat. The low-temperature, low-pressure refrigerant then passes through the second channel of the plate heat exchanger.

[0021] (3) Heat exchange process: The circulating water and refrigerant flow in the plate heat exchanger in a counter-current or cross-flow manner, so that the two media, the circulating water and the refrigerant, maintain a large temperature difference in a limited space, thereby improving the heat exchange efficiency. As the circulating water flows in the first flow channel of the plate heat exchanger, it continuously transfers heat to the metal plate and its own temperature gradually decreases. The low-temperature refrigerant absorbs heat and its temperature continuously rises, realizing the transfer of heat from the circulating water to the refrigerant. The refrigerant that has absorbed heat leaves the second flow channel of the plate heat exchanger and enters the compressor. Under the action of the compressor, the refrigerant is compressed and heated and pressurized. Then, in the condenser, the heat absorbed from the circulating water and the heat generated by compression are released to the external environment, completing the entire cycle of heat transfer and battery heat dissipation.

[0022] 2. When the air conditioner is not operating the heat pump, it does not need to absorb the waste heat from the battery radiator (if it is necessary to absorb the waste heat from the battery radiator, the condenser is switched to an evaporator, and the battery radiator is integrated on the evaporator side). Therefore, the battery radiator is integrated on the condenser side, and heat is dissipated through the fan of the second flow channel module of the heat exchanger and the battery radiator module. The method of heat dissipation is explained as follows: Figure 6 As shown, in the battery radiator module, the circulating water absorbs heat from the battery under the action of the water pump and flows to the battery radiator, transferring the heat to the battery radiator. At this time, the temperature of the battery radiator is relatively high. The fan blows the low-temperature air of the outside environment towards the battery radiator, releasing the heat on the battery radiator to the outside of the vehicle.

[0023] It should be noted that a corresponding battery radiator is designed based on the battery's cooling capacity and integrated into the condenser side of the shared air conditioner. Figure 1The expansion tank, the two-way water valves on the battery radiator side, the two-way water valves on the heat exchanger side, the first flow channel of the heat exchanger, the second flow channel of the heat exchanger, the first expansion valve, the second expansion valve, the evaporator, the condenser, the fan, the compressor, and the battery radiator are part of a shared air conditioning system.

[0024] The above embodiments can be applied to different external ambient temperature conditions, ensuring that the battery can effectively dissipate heat under various external ambient temperatures.

[0025] It should be noted that, Figures 5-7 Bold lines indicate flowing liquid, while non-bold lines indicate non-flowing liquid. For example... Figure 5 With the two water valves on the battery radiator side closed and the two water valves on the heat exchanger side open, circulating water flows in the first flow module of the heat exchanger, and refrigerant flows in the second flow module. The circulating water does not pass through the battery radiator. Figure 6 When the two water valves on the heat exchanger side are closed, or when the two water valves on the heat exchanger side are open, or when only the fan is working, the refrigerant does not flow in the second flow module of the heat exchanger, while the circulating water flows in the battery radiator module. The circulating water does not pass through the first flow channel of the heat exchanger.

[0026] In one embodiment of this utility model, such as Figure 7 As shown, the new energy air conditioning system further includes: a second flow channel module for heat exchange, which includes: the evaporator and the fan, with the fan located on the evaporator side; when a signal indicating that the battery is releasing heat is received, the ambient temperature is lower than the preset temperature, and the heat pump is turned on, the two water valves on the heat exchange side are closed, and the two water valves on the battery radiator side are opened, so that heat can be dissipated through the evaporator, the fan, and the battery radiator in the second flow channel module, and the waste heat from the battery radiator is absorbed by the evaporator.

[0027] The updated heat exchanger second flow channel module further includes: the heat exchanger second flow channel, the first expansion valve, the second expansion valve, the condenser, and the compressor; the first end of the first expansion valve, the first end of the second expansion valve, and the first end of the evaporator are connected in pairs; the second end of the first expansion valve is connected to the first end of the heat exchanger second flow channel; the second end of the second expansion valve is connected to the first end of the condenser; the second end of the heat exchanger second flow channel, the second end of the condenser, and the first end of the compressor are connected in pairs; and the second end of the compressor is connected to the second end of the evaporator.

[0028] In the above embodiments, when the ambient temperature is ≥5℃: the battery heat is dissipated to ensure normal battery operating temperature, and there is no need to recover and utilize the battery waste heat. When the ambient temperature is <5℃: because heat is precious in low-temperature environments, recovering the battery waste heat through a heat pump can be used for other purposes such as vehicle interior heating, improving energy utilization efficiency and maximizing energy use. Therefore, there is a need to recover and utilize the battery waste heat. If the heat pump is on, while using the battery radiator for heat dissipation, the evaporator can absorb and convert the waste heat generated during the battery heat dissipation process.

[0029] like Figure 7 As shown, the condenser is installed inside the vehicle, and the evaporator is installed outside the vehicle. When the ambient temperature is <5℃ and the heat pump is on, the battery radiator is integrated on the evaporator side (updating the second flow channel module replaces the condenser of the second flow channel module with an evaporator, and replacing the evaporator of the second flow channel module with a condenser). The waste heat generated during battery cooling is rapidly dissipated into the air by the fan, causing the temperature of the battery radiator to drop rapidly. The air carrying the heat enters the evaporator, where the evaporator converts the liquid refrigerant into a gaseous state, absorbing heat. The gaseous refrigerant carries this heat and is converted back into liquid refrigerant by the condenser, thereby releasing heat into the vehicle interior, for example, for vehicle interior heating.

[0030] like Figure 7 As shown, the refrigerant undergoes a cycle of compression-condensation-throttling-evaporation, specifically involving a compressor, condenser, fan, expansion valves (including the first and second expansion valves), and evaporator. The compressor's role is to provide power to the refrigerant. The low-temperature, low-pressure gaseous refrigerant exiting the evaporator (the evaporator converts the refrigerant from a liquid to a gaseous state, thereby absorbing heat) is drawn into the compressor and mechanically compressed into a high-temperature, high-pressure gaseous refrigerant. Part of this high-temperature, high-pressure gaseous refrigerant is cooled and liquefied by the condenser, releasing heat; the other part flows through the second channel of the plate heat exchanger to the first... An expansion valve throttles and reduces the pressure of the high-temperature, high-pressure gaseous refrigerant before it enters the evaporator. A second expansion valve throttles and reduces the pressure of the medium-temperature, high-pressure liquid refrigerant from the condenser (which converts the refrigerant from a gaseous state to a liquid state, thereby releasing heat) before it enters the evaporator. The residual heat generated during battery cooling is released into the air, and the air carrying the heat enters the evaporator. The evaporator converts the liquid refrigerant into a gaseous state and absorbs heat. The gaseous refrigerant, carrying this heat, passes through the condenser to convert the gaseous refrigerant back into a liquid refrigerant, thereby releasing the heat into the vehicle interior.

[0031] Existing heat pump-type electric air conditioners (integrated battery water cooling) can synchronize the lowest ambient temperature for battery cooling with the lowest operating temperature of the heat pump. However, low-temperature and ultra-low-temperature heat pumps are relatively expensive, and the battery's heat dissipation is independent of the ambient temperature, only related to the heat released internally by the battery. Therefore, below the minimum operating temperature of the heat pump, there is still a risk that the battery may require cooling but cannot. Compared to existing electric air conditioners (integrated battery water cooling), the above embodiment is lower in cost, solves the need for low-temperature battery cooling, achieves full coverage of ambient temperature for battery cooling, and enables the utilization of battery waste heat in low-temperature environments.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
