Description

TECHNICAL FIELD

[0001] The present application relates to a thermal management system, in particular to a vehicle-mounted air supplementing and enthalpy increasing system. BACKGROUND

[0002] The description in this part only provides background information related to the present application disclosure, and does not constitute prior art.

[0003] In the vehicle-mounted thermal management system, it is generally composed of the functions of compressing refrigerant, conveying or discharging cold gas, conveying or discharging hot gas, and in some scenarios, the LCC (water cooler) for water cooling heat dissipation is used as the condenser of the original thermal management system, and the Chiller (refrigerator) for water cooling is used as the evaporator of the original thermal management system, and by means of intelligent control of the circulation path of refrigerant and cooling liquid, high-efficiency refrigeration, heating and energy recovery are realized, which is especially suitable for electric vehicles and hybrid vehicles.

[0004] However, in real use scenarios, such as in special low-temperature environments, the low evaporation pressure of the heat pump may cause the suction density of the compressor to be small, resulting in a decrease in the mass flow rate of the refrigerant sucked by the compressor, and a high exhaust temperature, thereby forcing the compressor to operate at high load, affecting its temperature regulation ability and even the service life of the compressor itself. At the same time, considering the high integration requirement of the thermal management system in electric vehicles and hybrid vehicles for pipeline layout, the existing design generally has single cooling liquid pipeline layout considering factors such as cost and pipeline arrangement, which may further limit the vehicle-mounted temperature regulation function.

In addition, the drawings of the present application are only simple schematic illustrations, not the depiction according to the actual size, and the prior declaration. The following embodiments will further illustrate the related technical content of the present application in detail, but the disclosed content is not used to limit the protection scope of the present application.

[0056] It should be understood that although the terms such as "first", "second", "third" and the like may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used herein may include any one or more combinations of the associated listed items as appropriate.

[0057] Please refer to Figure 1 , a vehicle-mounted air supplement and enthalpy increasing system, wherein the vehicle-mounted air supplement and enthalpy increasing system comprises:

[0058] A water side valve island 1;

[0059] An agent side integrated mechanism 2, the agent side integrated mechanism 2 comprising a compressor 21, a water cooler 22, a liquid storage tank 25, a refrigerant expander 23, a refrigerant 24, the agent side integrated mechanism 2 further comprising an air supplement and enthalpy increasing mechanism, the air supplement and enthalpy increasing mechanism being arranged between the liquid storage tank 25 and the refrigerant expander 23 and being in communication with an input end of the compressor 21, the air supplement and enthalpy increasing mechanism being used for air supplementing the compressor 21;

[0060] A passenger cabin mechanism 3, the passenger cabin mechanism 3 comprising a cooler 31, a heater 32, and a blower 33 arranged on one side of the cooler 31 and the heater 32;

[0061] Downstream of the water cooler 22 includes a hot water three-way valve 7, so that the water cooler 22 is in series through the first water cooling passage water side valve island 1, or after the heater 32 and the water side valve island 1; downstream of the refrigeration device 22 includes a cold water three-way valve 8, so that the refrigeration device 24 is in series through the second water cooling passage water side valve island 1, or after the cooler 31 and the water side valve island 1;

[0062] The fan heat exchange mechanism 4 includes a fan heat exchange unit 41, and a heat exchange fan 42 arranged on one side of the fan heat exchange unit 41; the fan heat exchange unit 41 is in series with the water side valve island 1.

[0063] Based on the above structure, the water side valve island 1 is mainly used for collecting and heat exchanging the water flow of different temperatures introduced from the agent side integrated mechanism 2, the passenger cabin mechanism 3, the fan heat exchange mechanism 4 and the like, and the corresponding cold water and hot water can be mixed according to actual needs to realize temperature control. The water side valve island 1 can be realized by electric control, and the water side valve island 1 in the embodiment is a conventional multi-way valve body, such as a disc valve.

[0064] In actual operation, the compressor 21 compresses the low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant, which enters the downstream water cooler 22. The high-temperature and high-pressure refrigerant heats the water flow in the water cooler 22, and then flows to the liquid storage tank 25 to store excess liquid refrigerant. Part of the refrigerant flows to the gas supplement and enthalpy increasing mechanism, and then flows to the refrigeration device expansion valve 23 for throttling. After expansion and pressure reduction, the refrigerant becomes low-temperature and low-pressure refrigerant, and enters the downstream refrigeration device 24. The low-temperature and low-pressure refrigerant cools the water flow in the refrigeration device 24, and then returns to the compressor 21 from the suction port for the next cycle. At the same time, the heated water flow in the water cooler 22 provides hot water for the water side valve island 1, and the cooled water flow in the refrigeration device 24 provides cold water for the water side valve island 1.

[0065] The water cooler 22 in the agent side integrated mechanism 2 is mainly used for directly providing high-temperature water for the water side valve island 1, and the refrigeration device 24 is mainly used for providing low-temperature water for the water side valve island 1. The high-temperature water provided by the above refrigeration device 22 can be used to warm or dissipate heat for the corresponding elements with heat exchange function in the passenger cabin mechanism 3 and the fan heat exchange mechanism 4 when needed, and the low-temperature water provided by the refrigeration device 24 can be used to cool the corresponding elements with heat exchange function in the passenger cabin mechanism 3 and the fan heat exchange mechanism 4 when needed.

[0066] Meanwhile, in the present application, part of the high-temperature and high-pressure refrigerant in the above agent side integrated mechanism 2 can be cooled and decompressed to be transported back to the compressor to supplement gas during operation. The gas supplement and enthalpy increasing mechanism can include the following two forms of plate heat exchanger and flash tank.

[0067] A portion of the refrigerant enters the expansion valve 23 of the refrigeration unit for throttling, while another portion of the refrigerant passes through the gas replenishment and enthalpy enhancement mechanism and is input into the compressor 21, thereby achieving continuous gas replenishment and enthalpy enhancement for the compressor. Specifically, this application provides the following two gas replenishment and enthalpy enhancement structures.

[0068] Please see Figure 1 This is to achieve gas replenishment and enthalpy enhancement using a plate heat exchanger 26. The gas replenishment and enthalpy enhancement mechanism includes a plate heat exchanger expansion valve 27, a plate heat exchanger 26, a thermally coupled main plate heat exchanger circuit and a plate heat exchanger branch circuit. The compressor 21, the water cooler 22, the liquid storage tank 25, the main plate heat exchanger circuit, the cooler expansion valve 23, and the cooler 24 are arranged in series. The input end of the plate heat exchanger branch circuit is connected to a pipe for connecting the plate heat exchanger 26 and the cooler expansion valve 23 through a first flow channel. The plate heat exchanger expansion valve 27 is installed on the first flow channel. The other end of the plate heat exchanger branch circuit is connected to the input end of the compressor through a second flow channel. During the operation of the aforementioned refrigerant-side integrated mechanism 2, a portion of the refrigerant in the plate heat exchanger 26 enters the refrigeration expansion valve 23 for throttling, while the remaining refrigerant enters the plate heat exchanger expansion valve 27 via a branch of the plate heat exchanger for throttling. The low-temperature, low-pressure refrigerant formed after expansion and pressure reduction through the plate heat exchanger expansion valve 27 directly enters the plate heat exchanger 26, where it exchanges heat with the upstream high-temperature, high-pressure refrigerant. This allows the high-temperature, high-pressure refrigerant flowing into the refrigeration expansion valve 23 to be cooled in advance, increasing the subcooling before the valve and indirectly improving the cooling / heating capacity of the refrigerant after passing through the refrigeration expansion valve 23. Simultaneously, this allows the compressor 21 to be injected with refrigerant from the middle, rather than all of it from the refrigeration 24 side, to avoid excessively low pressure of the refrigerant injected from the refrigeration 24 side under extreme weather conditions, which could affect the normal operation of the compressor 21. Therefore, in this embodiment, the plate heat exchanger 26 installed in the refrigerant-side integrated mechanism can achieve enthalpy enhancement through gas replenishment, thereby improving the system's temperature regulation capability. In this invention, the refrigerant-side integrated mechanism 2 is integrated solely for the flow of refrigerant, offering high safety. Simultaneously, integrating the plate heat exchanger 26 into the refrigerant-side integrated mechanism 2 enables intermediate injection into the compressor 21, achieving continuous enthalpy replenishment and assisting in reducing the refrigerant temperature leading to the refrigerator 24, thus achieving the effect of enthalpy enhancement through gas replenishment. This is more energy-efficient and suitable for extreme environments. In this embodiment, the water-side valve island 1 with multiple outlets also allows for flexible mixing of water flow and pipeline organization, providing flexibility and practicality.

[0069] In this gas replenishment and enthalpy-increasing mechanism based on the plate heat exchanger 26 structure, multiple sensors are also used to adjust the plate heat exchanger 26. Specifically, for example... Figure 1As shown, the compressor 21 in the embodiment is connected in series with the first sensor 211 and the second sensor 212, respectively, for monitoring the pressure difference and temperature upstream and downstream of the compressor 21, and the third sensor 261 is further included between the plate heat exchanger 26 and the compressor 21 for monitoring the pressure and temperature of the refrigerant in the pipeline of the plate heat exchanger 26. With the assistance of the above three groups of pressure and temperature sensors, the refrigerant of the compressor 21 is monitored from the three pipelines connected with the compressor 21, respectively, so as to flexibly adjust the flow rate of the refrigerant and ensure the stable operation of the compressor 21. Of course, a temperature sensor can also be installed downstream of the plate heat exchanger 26, and a corresponding temperature sensor is also installed downstream of the plate heat exchanger expansion valve 27, so as to monitor the actual heat exchange efficiency of the plate heat exchanger 26 and ensure that the heat exchange efficiency of the plate heat exchanger 26 meets the operation requirements. For example, Figure 1 As shown, the fourth sensor 28 is installed downstream of the main pipeline of the plate heat exchanger in the embodiment, and the fifth sensor 29 is installed downstream of the branch pipeline of the plate heat exchanger, both of which are temperature sensors. In specific operation, first, a preset air supplement temperature difference value and a preset air supplement pressure value can be provided according to actual needs; the temperature Tmo between the main pipeline of the plate heat exchanger and the refrigeration device expansion valve and the temperature Tai between the branch pipeline of the plate heat exchanger and the plate heat exchanger expansion valve are monitored by the temperature sensor, and the difference between Tmo and Tai is calculated; the pressure Pm between the branch pipeline of the plate heat exchanger and the compressor is monitored by the pressure and temperature sensor; the difference between Tmo and Tai is compared with the preset difference value, for example, the difference between Tmo and Tai is not equal to the preset difference value, then the plate heat exchanger expansion valve is controlled to adjust the temperature of the refrigerant in the branch pipeline of the plate heat exchanger; Pm is compared with the preset air supplement pressure value, for example, Pm is not equal to the preset pressure value, then the plate heat exchanger expansion valve is controlled to adjust the pressure of the refrigerant in the branch pipeline of the plate heat exchanger. For example, in the above control method, the preset superheat degree can be set to 5K, therefore, whether Tmo-Tai=5K is calculated, then the plate heat exchanger expansion valve 27 does not need to be adjusted, otherwise it needs to be adjusted. The specific operation is to reduce the refrigerant flow to increase the superheat degree, or to increase the flow to reduce the superheat degree.

[0070] Please refer to Figure 8The gas supplement and enthalpy increase is realized by means of the flash tank 260. The gas supplement and enthalpy increase mechanism comprises the flash tank expansion valve 2601 and the flash tank 260, the flash tank 260 has a first output end and a second output end, wherein the compressor 21, the water cooler 22, the liquid storage tank 25, the refrigerant expansion valve 23, the input end and the first output end of the flash tank 260, the refrigerant expansion valve 23 and the refrigerant 24 are sequentially connected in series, the second output end of the flash tank 260 is communicated with the compressor 21 through the flash tank branch, the second output end of the flash tank 260 is higher than the first output end of the flash tank 260, during the operation of the above-mentioned agent side integration mechanism 2, after the preliminary expansion and pressure reduction of the flash tank expansion valve 2601, the liquid refrigerant in the flash tank 260 is subjected to secondary throttling in the refrigerant expansion valve 23 and refrigeration, and another part of the gaseous refrigerant is directly re-sucked into the compressor 21 to realize the supplement of enthalpy, so that the refrigerant is supplemented in the middle of the compressor 21, instead of being injected from the refrigerant 24 side, so as to avoid that the pressure of the heat-exchanged refrigerant injected from the refrigerant 24 side is too low in the extreme weather, and the normal operation of the compressor 21 is affected. Therefore, in the embodiment, the gas supplement and enthalpy increase can be realized by means of the parallelly connected flash tank 260 in the agent side integration mechanism, and the temperature regulation capacity of the system is improved. In the application, the agent side integration mechanism 2 is integrated, and is only used for the flow of refrigerant, so that the safety is high, and the flash tank 260 is integrated in the agent side integration mechanism 2, so that the refrigerant is injected in the middle of the compressor 21, the continuous supplement of enthalpy is realized, and the application is more energy-saving and suitable for extreme environments.

[0071] In the gas supplement and enthalpy increase mechanism based on the flash tank 260, a temperature sensor 2602 can be connected in series between the flash tank 260 and the refrigerant expansion valve 23, so that the temperature of the liquid refrigerant led out of the flash tank 260 can be detected, and the flow control between the refrigerant expansion valve 23 and the flash tank expansion valve 2601 can be cooperatively controlled.

[0072] In the embodiment, the four-way valve 9 is introduced, the water side valve island 1 is connected to the battery heat exchange unit 5 through the four-way valve 9, the water flow with a corresponding temperature is input into the battery heat exchange unit 5 through the water side valve island 1, and the temperature control of the battery heat exchange unit 5 is realized. Meanwhile, in the embodiment, the four-way valve 9 is also connected in series with the battery heat exchange unit 5 alone, and the four-way valve 9 is also connected in series with the water side valve island 1 alone, so that the water in the water side valve island 1 can be independently introduced through the four-way valve 9, the temperature of the water on the water path of the battery heat exchange unit 5 alone can be mixed and flowed, and the accurate temperature control of the battery heat exchange unit 5 can be realized. In another embodiment, the above-mentioned battery heat exchange unit 5 is also connected in series with a water kettle 51, and the water amount in the water path for the temperature control of the battery heat exchange unit 5 is stably controlled.

[0073] Similarly, the water-side valve island 1 is also connected to the drive motor heat exchange unit 6, and the water-side valve island 1 inputs water flow with corresponding temperature to the drive motor heat exchange unit 6 to control the temperature of the drive motor heat exchange unit 6. The drive motor heat exchange unit 6 is also connected in series with the water-side valve island 1 through the fan heat exchange unit 41, and therefore, in some cases, the temperature control of the drive motor heat exchange unit 6 can be assisted by the heat exchange between the fan heat exchange unit 41 and the external air.

[0074] The air blower 33 is arranged at one side of the cooler 31 and the heater 32, and is used to blow the low-temperature or high-temperature air passing through the cooler 31 and the heater 32 to the passenger cabin. Similarly, the heat exchange fan 42 is arranged at one side of the fan heat exchange unit 41, and is used to blow the air through the fan heat exchange unit 41 to the outside of the vehicle to realize heat exchange.

[0075] The following is an embodiment of various operation modes that can be realized based on the heat management system of the present application, wherein the preset pipeline switching is mainly realized by controlling the hot water three-way valve 7, the cold water three-way valve 8, the four-way valve 9 and the water-side valve island 1.
