[0030] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] In existing technologies, the components in a vehicle's thermal management system are arranged in a relatively dispersed manner, and the connections between these components are made through pipelines. This increases the volume of the flow channels in the thermal management system, leading to a larger amount of refrigerant being added. Since refrigerant is flammable and explosive, a large amount of refrigerant added can cause safety hazards. Furthermore, in the event of a vehicle collision, the refrigerant in the flow channels can ignite, affecting the safety of passengers. Therefore, how to optimize the structure of the vehicle's thermal management system to effectively and promptly handle the refrigerant in the event of a vehicle collision and prevent refrigerant ignition has become an urgent problem to be solved in this field.

[0032] The following is for reference. Figures 1-4 A thermal management system for a vehicle according to an embodiment of the present invention is described.

[0033] The thermal management system 1 for a vehicle according to the present invention includes: an integration unit and a discharge device 12. The integration unit is provided with a first heat exchange component and a second heat exchange component; wherein a refrigerant flow channel is formed inside the first heat exchange component, and a water-cooled flow channel adapted to exchange heat with the refrigerant flow channel is formed inside the second heat exchange component; the discharge device 12 is provided in the integration unit and has a discharge port communicating with the refrigerant flow channel, and the discharge device 12 is adapted to open the discharge port to discharge the refrigerant in the refrigerant flow channel when a vehicle collision occurs.

[0034] Specifically, the thermal management system 1 for vehicles of the present invention is mainly connected to the vehicle's electric drive system, battery system, and temperature control system or dehumidification system in the passenger compartment, etc. By using the refrigerant in the thermal management system 1 for heat exchange, effective temperature control of the entire vehicle's electric drive system, battery system, and passenger compartment is achieved.

[0035] The thermal management system 1 for vehicles of the present invention includes an integrated unit, in which a first heat exchange component and a second heat exchange component are provided. A refrigerant flow channel is formed inside the first heat exchange component, and a water-cooled flow channel is formed inside the second heat exchange component. The refrigerant achieves heat exchange through a phase change. For example, the refrigerant is in a liquid state at low temperature and low pressure. After absorbing heat, the liquid refrigerant gradually transforms into a gaseous state, but it is not completely vaporized at this time, forming a gas-liquid mixture. After the liquid refrigerant absorbs heat from the air, its temperature and pressure will rise. At this time, the refrigerant begins to turn into a gaseous state. The gaseous refrigerant exchanges heat with air or water, releases heat, and gradually cools into a liquid state. The refrigerant in the refrigerant flow channel absorbs or releases heat through a phase change. A water-cooled flow channel suitable for exchanging heat with the refrigerant in the refrigerant flow channel is formed inside the second heat exchange component. The water in the water-cooled flow channel exchanges heat with the refrigerant flow channel to achieve temperature regulation, thereby achieving effective temperature control of the vehicle's electric drive system, battery system, and passenger compartment.

[0036] In this application, the first heat exchange component and the second heat exchange component are integrated into an integrated unit, which is beneficial to reduce the size of the thermal management system 1 and achieve miniaturization. Furthermore, by integrating the first heat exchange component and the second heat exchange component into an integrated unit, the refrigerant flow channel inside the integrated unit can be shortened, thereby reducing the refrigerant capacity in the refrigerant flow channel. Since refrigerant has flammable and explosive properties, shortening the length of the refrigerant flow channel and reducing the refrigerant capacity facilitates the arrangement and maintenance of the refrigerant flow channel, improves the quality of the refrigerant flow channel, and reduces the risk of refrigerant leakage. At the same time, it can significantly reduce the amount of refrigerant added and increase the structural strength of the integrated unit, thereby improving the safety of the thermal management system 1.

[0037] An exhaust device 12 is provided on the integrated unit, and the exhaust device 12 is connected to the refrigerant flow channel. An exhaust port is formed on the exhaust device 12 to discharge the refrigerant in the refrigerant flow channel. Since the refrigerant is flammable and explosive, when a vehicle collision occurs, the refrigerant in the integrated unit is prone to ignition, causing safety problems. Therefore, an exhaust device 12 is provided on the integrated unit, and the exhaust device 12 is connected to the refrigerant flow channel. When a vehicle collision occurs, the exhaust device 12 can discharge the refrigerant from the exhaust port to the area where the air flows outside the integrated unit. The refrigerant mixes with the air outside the integrated unit and is thus completely diluted by the outside air, thereby reducing the risk of combustion and explosion of the refrigerant inside the thermal management system 1 and improving the safety performance of the entire vehicle.

[0038] The emission device 12 can guide the refrigerant to the outside of the vehicle body. The air flow speed outside the vehicle body is faster, which helps to accelerate the dilution efficiency of the refrigerant. At the same time, in the event of a vehicle collision, the integrated unit can be controlled to shut down. After the integrated unit is shut down, the refrigerant will not continue to flow in the integrated unit for heat exchange. This facilitates the centralized emission of the refrigerant in the refrigerant channel through the emission device 12, improving the emission efficiency of the refrigerant and further ensuring vehicle safety.

[0039] The thermal management system 1 for vehicles according to the present invention integrates the first heat exchange component and the second heat exchange component into an integrated unit. The refrigerant flow channel inside the integrated unit can be shortened, thereby reducing the refrigerant capacity in the refrigerant flow channel. Since the refrigerant has flammable and explosive properties, shortening the length of the refrigerant flow channel reduces the refrigerant capacity, facilitates the arrangement and maintenance of the refrigerant flow channel, improves the quality of the refrigerant flow channel, and reduces the risk of refrigerant leakage. Furthermore, an exhaust device 12 is provided on the integrated unit. The exhaust device 12 can open the exhaust port and discharge the refrigerant to the outside for dilution when the vehicle is involved in a collision, thereby preventing the refrigerant from burning due to the vehicle collision and improving the safety of the entire vehicle.

[0040] In some embodiments, a refrigerant temperature sensor and a pressure sensor can be installed on the integrated unit. The refrigerant temperature sensor and the pressure sensor are connected to the refrigerant flow channel and are adapted to monitor the refrigerant pressure and temperature in the refrigerant flow channel. During the process of opening the discharge device 12 and discharging the refrigerant, the refrigerant temperature sensor and the pressure sensor monitor the refrigerant status in real time. When the temperature and pressure of the refrigerant are detected to reach the preset value, there is no need to continue discharging the refrigerant. The discharge device 12 can be turned off to avoid excessive refrigerant discharge and waste of refrigerant.

[0041] According to some embodiments of the present invention, the thermal management system 1 further includes a collision detection device disposed on the vehicle body and adapted to issue a collision signal when a collision occurs; wherein, the emission device 12 is electrically connected to the collision detection device and adapted to open the emission port after receiving the collision signal.

[0042] Specifically, a collision detection device is installed on the vehicle body. When the vehicle is involved in a frontal or side collision, or when a collision is imminent, the collision detection device can promptly issue a collision signal. The collision detection device is electrically connected to the emission device 12. Upon receiving the collision signal from the collision detection device, the emission device 12 can open its emission port to release the refrigerant. By electrically connecting the emission device 12 to the collision detection device, the emission device 12 will only open its emission port to release the refrigerant after receiving a collision signal. This ensures that the emission device 12 remains closed under normal vehicle conditions, and that the emission device 12 will not affect the operation of the integrated unit, thus ensuring the working efficiency of the heat exchange system. Furthermore, by electrically connecting the emission device 12 to the collision detection device, the response speed of the emission device 12 can be accelerated, enabling timely and rapid refrigerant release.

[0043] In some embodiments, the collision detection device can be configured as an acceleration sensor and a collision sensor. The acceleration sensor and the collision sensor can emit a collision signal when a vehicle collision occurs, or they can determine the likelihood of a collision when a vehicle is about to collide, and alert the occupants of the vehicle to improve vehicle safety.

[0044] According to some embodiments of the present invention, the emission device 12 is disposed outside the integrated unit.

[0045] Specifically, the discharge device 12 is located outside the integrated unit, specifically outside the first heat exchange component, which facilitates the arrangement and installation of the discharge device 12, as well as its maintenance and repair. The discharge device 12 is connected to the refrigerant flow channel. When the discharge device 12 is closed, it will not affect the flow of refrigerant inside the integrated unit, ensuring the stable operation of the integrated unit. When the discharge device 12 is turned on and discharges the refrigerant, since the discharge device 12 is located outside the integrated unit, it is more convenient to guide the refrigerant to the outside of the vehicle body, thereby improving the discharge efficiency and dilution efficiency of the refrigerant.

[0046] According to some embodiments of the present invention, the first heat exchange component includes a compressor 111, a plate heat exchanger 112, and a liquid receiver 113. The plate heat exchanger 112 and the liquid receiver 113 are integrally disposed and located on one side of the compressor 111 along its length. The plate heat exchanger 112 and the liquid receiver 113 form refrigerant flow channels that communicate with each other. The compressor 111 has a return flow channel that communicates with the refrigerant flow channels. The discharge device 12 includes: a valve seat 121, which is disposed on one side of the compressor 111 along its width. The valve seat 121 has a discharge channel that communicates with the return flow channel. The outlet of the discharge channel is a discharge port. The discharge valve 122 is disposed on the side of the valve seat 121 away from the compressor 111 and can be selectively opened to discharge refrigerant from the discharge port.

[0047] Specifically, the compressor 111 is mainly used to compress low-pressure gaseous refrigerant into high-pressure gaseous refrigerant, while the plate heat exchanger 112 and the receiver 113 are mainly used for temperature control. By integrating the plate heat exchanger 112 and the receiver 113 and placing them on one side of the compressor 111 along its length, the integration and structural strength of the compressor 111, plate heat exchanger 112, and receiver 113 are improved. This also helps to improve the total volume of the refrigerant flow channels inside the compressor 111, plate heat exchanger 112, and receiver 113, facilitating a reduction in the amount of refrigerant charged. Furthermore, by integrating the compressor 111, plate heat exchanger 112, and receiver 113... The compressor 111, plate heat exchanger 112, and receiver 113 are integrated into a single unit, directly connected to achieve assembly of the thermal management system 1 and connection of the internal refrigerant flow channels. Compared with connecting pipes to connect various components, this reduces the number of connecting pipes, improves the integration of the thermal management system 1, reduces the total flow channel volume of the thermal management system 1, reduces the risk of refrigerant leakage, and improves the safety of the thermal management system 1. Furthermore, by integrating the compressor 111 as one integrated assembly and the plate heat exchanger 112 and receiver 113 as another integrated assembly, the assembly time of the thermal management system 1 can be saved, and the hierarchical assembly of the assembly line can be met.

[0048] The plate heat exchanger 112 and the liquid receiver 113 are provided with refrigerant channels that are connected to each other. The refrigerant flows from the compressor 111 into the refrigerant channels in the plate heat exchanger 112 and the liquid receiver 113 and exchanges heat with the coolant in the water-cooled channel. After the heat exchange is completed, the refrigerant returns to the compressor 111 to complete one cycle.

[0049] The plate heat exchanger 112 and the liquid receiver 113 are stacked to enhance the functional integration of the plate heat exchanger 112 and the liquid receiver 113. Utilizing the structural characteristics of the plate heat exchanger 112, namely the close arrangement of the plates, the plate heat exchanger 112 occupies less floor space and space compared to other types of heat exchangers. The liquid receiver 113 and the plate heat exchanger 112 can be connected as a whole by means such as integral brazing.

[0050] Inside the compressor 111, a return flow channel is formed that is connected to the refrigerant flow channel. Low-temperature and low-pressure gaseous refrigerant flows from the low-pressure side to the high-pressure side through the return flow channel, forming high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant enters the refrigerant flow channel in the plate heat exchanger 112 and the liquid receiver 113 through the compressor 111 for heat exchange, generating low-temperature and low-pressure gaseous refrigerant. The low-temperature and low-pressure gaseous refrigerant flows back to the compressor 111 through the return flow channel, completing one cycle.

[0051] In some embodiments, the compressor 111 housing is provided with a high-pressure chamber and a low-pressure chamber that communicate with each other to form a return flow channel. The high-pressure chamber is located close to the plate heat exchanger 112 and the liquid receiver 113 to ensure that the generated high-temperature and high-pressure gaseous refrigerant flows to the plate heat exchanger 112 and the liquid receiver 113 through the shortest path, thereby reducing heat and pressure loss and simplifying the flow path between the plate heat exchanger 112, the liquid receiver 113 and the compressor 111.

[0052] The return flow path includes a first return flow path 1111 and a second return flow path 1112, such as... Figure 3 As shown, a first protrusion 1113 is provided on the compressor 111, and a first return air passage 1111 is formed inside the first protrusion 1113. The first protrusion 1113 serves as the processing carrier for the first return air passage 1111, which facilitates the connection of the first return air passage 1111 to the low-pressure chamber, ensuring the normal operation of the refrigeration and heating cycles. Compared with using connecting pipes to connect the plate heat exchanger, the liquid receiver, and the compressor 111, this effectively reduces the number of connecting pipes, improves the integration of the compressor 111, reduces the space occupied, and at the same time ensures the reliable circulation of the refrigerant.

[0053] The compressor 111 is also provided with a second protrusion 1114. The second protrusion 1114 has a second return flow channel 1112 that connects the high-pressure chamber and the low-pressure chamber. The second protrusion 1114 serves as the processing carrier for the second return flow channel 1112, which forms the second return flow channel 1112 that passes through the high-pressure chamber and the low-pressure chamber. This helps to improve the flow path integration inside the compressor 111. It also helps to promote the recirculation of the other part of the refrigerant that has not reached the high temperature and high pressure through the second return flow channel 1112 when a part of the refrigerant flowing out of the high-pressure chamber flows toward the plate heat exchanger 112 and the liquid receiver 113. This helps to increase the refrigerant flow through the compressor 111 and improve the output power of the compressor 111.

[0054] In the embodiment of the present invention, the discharge device 12 is disposed in the compressor 111 housing and communicates with the first return air passage 1111, and the refrigerant discharge line of the discharge device 12 for discharging refrigerant is as follows: Figure 4 As shown.

[0055] According to some embodiments of the present invention, the discharge device 12 includes a valve seat 121 and a discharge valve 122. The valve seat 121 is disposed on one side of the compressor 111 in the width direction. A discharge channel communicating with the return air passage is formed inside the valve seat 121. The outlet of the discharge channel is configured as a discharge port. The discharge valve 122 is disposed on the side of the valve seat 121 away from the compressor 111 and can be selectively opened to discharge refrigerant from the discharge port.

[0056] like Figure 1As shown, a valve seat 121 is provided on the housing of the compressor 111. A discharge channel communicating with the return air passage is formed inside the valve seat 121. The discharge valve 122 can be connected to the valve seat 121 by threads and a sealing ring. The assembly is simple, and by setting the sealing ring, the seal between the valve seat 121 and the discharge valve 122 can be guaranteed to avoid refrigerant leakage.

[0057] A discharge channel communicating with the return air passage is formed inside the valve seat 121. The outlet of the discharge channel is a discharge port. The discharge valve 122 opens after receiving a collision signal and controls the refrigerant to flow from the cooling passage into the discharge channel and be discharged to the outside through the discharge port. The discharge port is located on the side of the valve seat 121, which is more conducive to the discharge of refrigerant. The discharge valve 122 is located on the side of the valve seat 121 away from the compressor 111. The installation and removal of the discharge valve 122 will not affect the arrangement of the compressor 111, the plate heat exchanger 112 and the liquid receiver 113. The arrangement of the discharge valve 122 is more reasonable.

[0058] According to some embodiments of the present invention, the emission device 12 further includes an emission pipe 123 disposed on the valve seat 121, one end of the emission pipe 123 communicating with the emission port, and the other end extending to the outside of the vehicle body.

[0059] like Figure 1 and Figure 2 As shown, a discharge pipe 123 is provided at the discharge port of valve seat 121. One end of the discharge pipe 123 is connected to the discharge port, and the other end is led out to the outside of the vehicle body. The refrigerant is diverted by the discharge pipe 123 and discharged to the outside of the vehicle body in conjunction with the discharge valve 122. This accelerates the dilution of the refrigerant, prevents the refrigerant from being directly discharged into the thermal management system 1 and causing a fire, and improves the safety of the whole vehicle.

[0060] According to some embodiments of the present invention, the discharge valve 122 is configured as a solenoid valve.

[0061] Specifically, compared to other valve body structures, solenoid valves can be electrically connected to collision detection devices to achieve automated control. Furthermore, solenoid valves have a simple structure, low price, and lower installation and maintenance costs. They also offer good sealing performance and rapid opening and closing. Upon receiving a collision command, the solenoid valve can quickly open and discharge refrigerant to the outside, improving safety. When no collision command is received, the solenoid valve remains closed to prevent refrigerant leakage. Solenoid valves can regulate parameters such as refrigerant flow rate and velocity, ensuring both precision and flexibility in use.

[0062] According to some embodiments of the present invention, the second heat exchange component includes a condenser 131, a subcooler 132, and an evaporator 133. The condenser 131, the subcooler 132, and the evaporator 133 are sequentially disposed on top of the plate heat exchanger 112 and the liquid receiver 113, and the condenser 131, the subcooler 132, and the evaporator 133 are integrally disposed with the liquid receiver 113.

[0063] Specifically, the second heat exchange component includes a condenser 131, a subcooler 132, and an evaporator 133, such as Figure 1 As shown, the liquid receiver 113 is located between the condenser 131 and the evaporator 133. The refrigerant flowing out of the condenser 131 is in a gas-liquid mixed state. By utilizing the built-in flow channel of the liquid receiver 113, the liquid refrigerant can be separated into two liquid states in the liquid receiver 113. Then, through the bottom corner hole of the liquid receiver 113, the liquid refrigerant flows out and flows to the evaporator 133, ensuring the evaporation rate of the evaporator 133. This ensures that the refrigerant expands in the evaporator 133 and fully absorbs the heat of the coolant, thereby improving the heat exchange efficiency between the refrigerant flow channel and the water cooling flow channel.

[0064] The water-cooled flow channel flowing through the condenser 131 can be used to control the temperature and humidity inside the passenger compartment. The water-cooled flow channel flowing through the evaporator 133 can be used to control the temperature of the battery system and the temperature and humidity inside the passenger compartment. The remaining water-cooled flow channels can be equipped with additional plate heat exchangers 112 or independent external radiators to control the temperature of the electric drive system, so that the various functional systems of the vehicle can reach a good operating state, ensuring the driving and riding comfort of the driver and passengers, and also ensuring the stable and reliable operation of the vehicle.

[0065] Placing the receiver 113 between the condenser 131 and the evaporator 133, and rationally designing the flow paths between the receiver 113, the condenser 131, and the evaporator 133, ensures that the flow paths between the condenser 131 and the receiver 113, and between the receiver 113 and the evaporator 133, are as short as possible. This helps to simplify the flow paths within the plate heat exchanger 112 and the receiver 113, avoids excessive pressure and heat loss due to excessively long flow paths, and improves the smoothness of refrigerant flow and the heat exchange efficiency with the corresponding coolant.

[0066] A liquid receiver 113 is provided between the subcooler 132 and the evaporator 133, or between the subcooler 132 and the condenser 131. The subcooler 132 can perform secondary heat exchange between the condensed saturated liquid and the coolant, further increasing the subcooling of the refrigerant and reducing the flash gas generated by the refrigerant during the throttling process. This helps to increase the evaporation rate of the evaporator 133 and improve the heat exchange efficiency.

[0067] According to some embodiments of the present invention, the thermal management system 1 further includes: a refrigerant valve, wherein the refrigerant valve is configured as a plurality of valves and is respectively connected to a refrigerant flow channel, and the refrigerant valve is adapted to control the flow of refrigerant in the refrigerant flow channel.

[0068] Specifically, in order to regulate the refrigerant flow rate in the evaporator 133, a refrigerant valve is also provided in the thermal management system 1. The refrigerant valve is constructed in multiple ways. Among them, a first refrigerant valve 141 is provided at the inlet of the evaporator 133. On the one hand, it controls the flow rate of refrigerant entering the evaporator 133, ensuring that the refrigerant flowing out of the evaporator 133 outlet is in a gaseous state, reducing the content of liquid refrigerant, thereby reducing the possibility of liquid slugging when the refrigerant enters the compressor 111, ensuring the cooling capacity of the evaporator 133, and improving the heat exchange efficiency. On the other hand, it can turn the low-temperature and high-pressure liquid refrigerant into a low-temperature and low-pressure mist-like liquid refrigerant after passing through the throttling of the first refrigerant valve 141, satisfying the evaporation conditions of the refrigerant, thereby improving the evaporation heat absorption efficiency.

[0069] In order to regulate the flow rate and pressure of the refrigerant entering the low-pressure chamber from the return flow channel, a second refrigerant valve 142 is provided on the compressor 111. The second refrigerant valve 142 is used to control the flow rate of the refrigerant from the return flow channel to the low-pressure chamber, and to control the low-temperature high-pressure refrigerant to become a low-temperature low-pressure refrigerant.

[0070] When a vehicle collision occurs, the collision detection device sends a collision signal, the compressor 111 stops working, and at the same time, the first refrigerant valve 141 and the second refrigerant valve 142 are opened simultaneously, so that the refrigerant can flow freely in the return flow channel and the refrigerant flow channel, and the discharge valve 122 discharges the refrigerant more efficiently.

[0071] According to some embodiments of the present invention, the thermal management system 1 further includes an integrated controller 15, which is electrically connected to the integrated unit and adapted to control the opening or closing of the integrated unit.
