Description

Technical Field

[0001] The utility model belongs to the technical field of automobile thermal management, and in particular relates to a refrigerant circuit integrated module and a vehicle thermal management system. Background Art

[0002] New energy vehicles are gradually being recognized by the market for their many advantages, including high driving / riding experience, technological configuration, and low cost of use. However, range anxiety, especially the problem of discounted range in winter, is becoming more and more prominent. With the increase in the number of new energy vehicles, reducing carbon emissions and reducing the greenhouse effect of thermal management fluids are also being put on the regulatory agenda. The thermal management system of future generations of new energy vehicles is gradually developing around better performance and more environmentally friendly directions. Compared with the currently widely used R134a refrigerant, R290 (propane) has better low-temperature performance, less charge and is more environmentally friendly. Therefore, R290 is widely recognized as one of the alternative refrigerants for the next generation of thermal management systems.

In addition, each module is independent of each other, the installation integration is low, the integrated components are relatively scattered, and they occupy a large space. Considering that R290 is a flammable refrigerant and has a higher working pressure, when applying the R290 thermal management system, in addition to system performance and cost, how to optimize the connection structure, reduce the number of pipeline connections, and effectively avoid refrigerant leakage are also points that need to be considered.

Changes or adjustments to their relative relationships should be regarded as the scope of the implementation of the present utility model without substantially changing the technical content.

[0045] In order to describe the present invention in detail, the refrigerant circuit integrated module of the present invention is specifically described below:

[0046] Please combine Figures 1 to 5 As shown, the utility model provides a refrigerant circuit integrated module, including a compressor 10, a condenser 20, a battery cooler 30 and a flow channel plate 60, wherein the compressor 10 has a shell; the condenser 20 is installed on the shell; the battery cooler 30 is installed on the shell and is located on the same side of the compressor 10 as the condenser 20; the flow channel plate 60 is arranged between the compressor 10 and the battery cooler 30; the compressor 10, the condenser 20, the flow channel plate 60 and the battery cooler 30 are connected in series in the refrigerant circulation circuit.

[0047] Specifically, the installation of each component of the refrigerant circuit integrated module is a standard interface, which is compatible with condensers 20 battery coolers 30 of different power levels and compressors 10 of different displacements, and the module configuration can be flexibly adjusted based on different models and different vehicle requirements. Among them, the battery cooler 30 and the condenser 20 are installed on the housing of the compressor 10 to form a compact structure. In this embodiment, the battery cooler 30 and the condenser 20 are arranged on the same side of the compressor 10, and are arranged side by side in the vertical direction, and the battery cooler 30 is located above the condenser 20. The refrigerant is recycled back to the compressor 10 through the compressor 10, the condenser 20, the flow channel plate 60 and the battery cooler 30. By arranging the condenser 20 and the battery cooler 30 side by side on the same side of the compressor 10 housing, and the flow channel plate 60 is arranged between the compressor 10 and the battery cooler 30, the occupied space of the overall module is significantly reduced. This compact integrated design makes the integrated module easier to install and integrate into various devices or systems, especially suitable for application scenarios with limited space. The compressor 10, the condenser 20 and the battery cooler 30 are directly connected through multiple connection interfaces, and the refrigerant can circulate in a continuous loop without the need for additional pipes or connectors, which not only reduces the risk of refrigerant leakage, but also improves the efficiency of the refrigerant cycle, helping to achieve a faster and more stable cooling effect. The design of multiple connection interfaces makes the connection between the various components simpler and clearer, and is easy to operate and maintain. When a component needs to be repaired or replaced, the corresponding connection interface can be easily disconnected without affecting the integrity of the entire refrigerant circuit. This structure can effectively improve space utilization and facilitate vehicle layout; optimize the connection structure, reduce the number of pipeline connections, and effectively reduce the risk of refrigerant leakage; shorten the length of the pipeline connection, reduce the circuit pressure drop and heat transfer, and effectively improve the system performance; the reasonable arrangement of components and structural design can effectively improve the safety performance of the R290 refrigerant thermal management system.

[0048] See also Figure 1In some embodiments, a mounting portion 11 for connecting to a vehicle body is provided on a first side of the housing of the compressor 10, and the condenser 20 and the battery cooler 30 are located on a second side of the housing, and the first side and the second side are two opposite sides of the housing. Specifically, the mounting portion 11 includes a plurality of connecting columns, and the plurality of connecting columns are arranged around the center of gravity. In this embodiment, the mounting portion 11 includes three connecting columns, and the three connecting columns are arranged in a triangular shape around the center of gravity. The center of gravity is the center of gravity of the entire refrigerant circuit integrated module, and the three connecting columns are arranged in a triangular shape along the center of gravity, and are connected to the vehicle body of the entire vehicle through the mounting holes on the connecting columns. This structure is conducive to ensuring the reliability of the connection and assembly, while reducing the occupied space and facilitating assembly. The mounting portion 11 with a triangular layout not only provides a stable support, but also enhances the structural strength of the entire housing of the compressor 10. In a complex and changeable driving environment, this design can effectively resist external shocks and vibrations, reduce the risk of damage caused by mechanical stress, and improve the reliability and service life of the entire module. The compressor 10 design with the triangularly arranged mounting portion 11 is highly adaptable and can meet the installation requirements and space limitations of different vehicle models.

[0049] In the above embodiment, each connecting column of the mounting portion 11 includes a first connecting section and a second connecting section connected to each other, the first connecting section is connected to the shell, the second connecting section is provided with a connecting hole, and a weakening structure (not shown) is provided between the first connecting section and the second connecting section. Specifically, in this embodiment, the weakening structure is a circle of annular grooves provided on the connecting column near the mounting hole, the wall thickness of the annular groove is thinner than the wall thickness of other parts of the mounting portion 11, and it is a local structural weak point. When the vehicle is subjected to a large frontal impact, or the impact acceleration is greater than a specified value, the root position of the annular groove will break, causing the refrigerant circuit integrated module to sink as a whole, avoiding intrusion into the passenger compartment and threatening the safety of passengers and the vehicle.

[0050] See also Figure 3In some embodiments, the condenser 20 is provided with a first pipeline interface 21, and the battery cooler 30 is provided with a second pipeline interface 31. The first pipeline interface 21 and the second pipeline interface 31 are arranged on the same side and in the same direction. Specifically, in this embodiment, two first pipeline interfaces 21 are provided on the condenser 20, and two second pipeline interfaces 31 are provided on the battery cooler 30. The first pipeline interface 21 and the second pipeline interface 31 are arranged on the side away from the compressor 10 and in the same direction. The first pipeline interface 21 and the second pipeline interface 31 can be staggered or arranged along the same line. In this way, the pipeline connection with the coolant circuit of the whole vehicle is significantly simplified, and the interface position can be determined intuitively and quickly, and the pipeline connection is performed without additional adjustment or turning, which greatly improves the installation efficiency; and reduces the pipeline length, so that the layout of the entire refrigerant circuit integrated module is more compact, which is not only conducive to reducing the space occupied by the module, but also helps to improve the stability and reliability of the overall structure; in addition, when the pipeline or interface needs to be inspected or replaced, the staff can more easily approach and operate these interfaces, reducing the difficulty and cost of maintenance.

[0051] See also Figure 1 and Figure 4It can be understood that the refrigerant circuit integrated module also includes a liquid storage dryer 40, which is connected to the side of the condenser 20 facing the compressor 10, the inlet of the condenser 20 is connected to the outlet 13 of the compressor, and the outlet of the condenser 20 is connected to the inlet of the liquid storage dryer 40. Specifically, the liquid storage dryer 40 is a rectangular parallelepiped structure, which is arranged below the condenser 20, that is, the side of the condenser 20 facing the compressor 10, and is welded to the condenser 20 to ensure mechanical and sealing connection. This structure allows the refrigerant to first enter the condenser 20 for cooling after being compressed by the compressor 10, and then enter the liquid storage dryer 40. This layout ensures the smoothness of the refrigerant flow and improves the circulation efficiency of the refrigerant circuit; this design not only reduces additional connecting pipes and joints, reduces the risk of leakage, but also makes the structure of the entire module more compact, occupies less space, and is convenient for installation and layout in a limited space. The liquid storage dryer 40 is connected to the condenser 20 as a whole by welding, which not only ensures the mechanical strength between the two, but also achieves good sealing performance. This connection method can effectively prevent refrigerant leakage and improve the reliability and stability of the entire refrigerant circuit. Since the liquid storage dryer 40 is integrated with the condenser 20, the installation process is simpler and faster. At the same time, during maintenance, only the entire module needs to be inspected and repaired, and there is no need to disassemble the liquid storage dryer 40 separately, which reduces the maintenance cost and difficulty. In addition, the liquid storage dryer 40 is provided with liquid storage dryer mounting holes that are mechanically connected to the compressor 10, the flow channel plate 60, and the battery cooler 30, respectively, to facilitate the assembly and connection of the battery cooler 30 with the compressor 10, the flow channel plate 60 and the liquid storage dryer 40, respectively.

[0052] It should be noted that the liquid storage dryer 40 is provided with a heat insulation structure (not shown), which can isolate the high-temperature pipeline connected to the outlet 13 of the compressor from the medium-temperature pipeline connected to the outlet of the condenser 20, so as to reduce heat cross-talk and improve system performance. By reducing the transfer of heat between different pipelines, the heat insulation structure helps to maintain the temperature balance of various parts in the refrigerant circuit. Since the heat insulation structure reduces heat loss and unnecessary energy consumption, the energy efficiency of the refrigerant circuit integrated module is improved. Reducing heat cross-talk and maintaining a stable temperature environment help to reduce the thermal load and mechanical stress of various components of the system. This not only reduces the wear and failure rate of components, but also extends the service life of the entire refrigerant circuit integrated module.

[0053] See also Figure 1 , Figure 2 and Figure 5In the above embodiment, the refrigerant circuit integrated module further includes an expansion valve 50, which is located between the liquid storage dryer 40 and the battery cooler 30, and the inlet of the expansion valve 50 is communicated with the outlet of the liquid storage dryer 40, and the outlet of the expansion valve 50 is communicated with the inlet of the battery cooler 30. Specifically, the refrigerant enters the compressor 10 again through the refrigerant circuit formed by the compressor 10, the condenser 20, the liquid storage dryer 40, the expansion valve 50, and the battery cooler 30 in sequence, and circulates in the refrigerant circuit. The expansion valve 50 is located between the liquid storage dryer 40 and the battery cooler 30, and ensures that the battery cooler 30 obtains an appropriate amount of refrigerant supply by accurately controlling the flow rate of the refrigerant entering the battery cooler 30. The expansion valve 50 plays a role of pressure regulation in the refrigerant circuit. It can automatically adjust the opening according to the pressure and temperature changes of the refrigerant circuit to maintain the pressure balance in the refrigerant circuit. By accurately controlling the flow rate and pressure of the refrigerant, the expansion valve 50 helps to improve the working efficiency of the entire refrigerant circuit integrated module.

[0054] See also Figure 1 , Figure 5 , Figures 6 to 9It can be understood that the flow channel plate 60 is disposed between the compressor 10 and the battery cooler 30, and a plurality of flow channels are disposed inside the flow channel plate 60. The liquid storage dryer 40, the expansion valve 50, the battery cooler 30 and the compressor 10 are respectively connected to the flow channel plate 60 and communicated with the flow channels in the flow channel plate 60, so that the refrigerant enters the compressor 10 through the liquid storage dryer 40, the expansion valve 50 and the battery cooler 30 in sequence. Specifically, a plurality of flow channel plate mounting holes are disposed on the flow channel plate 60, which are respectively used for assembly and connection with the battery cooler 30, the liquid storage dryer 40 and the compressor 10. In this way, the condenser 20 and the liquid storage dryer 40 are assembled as one, the liquid storage dryer 40 is mechanically connected to the compressor 10, the battery cooler 30 and the flow channel plate 60 respectively through threaded fasteners, and the flow channel plate 60 is mechanically connected to the liquid storage dryer 40, the battery cooler 30 and the compressor 10 respectively through threaded fasteners, thereby realizing the integrated assembly of the compressor 10, the condenser 20, the flow channel 60 and the battery cooler 30. Through the connection channel between the compressor 10 and the condenser 20, the connection channel between the condenser 20 and the liquid storage dryer 40, and the flow channel of the flow channel plate 60 connecting the liquid storage dryer 40, the expansion valve 50, the battery cooler 30 and the compressor 10, a complete refrigerant circuit is formed to ensure that the refrigerant can work in the refrigerant circuit integrated module. The design of the flow channel plate 60 makes the structure of the entire refrigerant circuit integrated module more compact. By connecting the liquid storage dryer 40, the expansion valve 50, the battery cooler 30 and the compressor 10 to the flow channel plate 60, and using the flow channel in the flow channel plate 60 to realize the circulation of the refrigerant, the additional connecting pipes and joints are effectively reduced, making the space occupied by the entire module smaller and convenient for layout in a limited installation space. The flow channel length and overall envelope size inside the flow channel plate 60 are small, and the circulation path of the refrigerant in the circuit is relatively short, which can effectively reduce the refrigerant charge amount, which not only reduces the cost of the refrigerant, but also reduces the pressure fluctuation and leakage risk caused by excessive refrigerant, and improves the stability and reliability of the system.

[0055] See also Figures 6 to 9In the above embodiment, the flow channel plate 60 includes a flow channel plate body 61, on which a liquid storage dryer outlet interface 62, an expansion valve inlet interface 63, an expansion valve outlet interface 64, a cooler inlet interface 65, a cooler outlet interface 66 and a compressor inlet interface 67 are provided. The liquid storage dryer outlet interface 62 is connected to the outlet of the liquid storage dryer 40, the expansion valve inlet interface 63 is connected to the inlet of the expansion valve 50, the expansion valve outlet interface 64 is connected to the outlet of the expansion valve 50, the cooler inlet interface 65 is connected to the inlet of the battery cooler 30, the cooler outlet interface 66 is connected to the outlet of the battery cooler 30, and the compressor inlet interface 67 is connected to the inlet 12 of the compressor. Among them, a first flow channel is formed between the liquid storage dryer outlet interface 62 and the expansion valve inlet interface 63, a second flow channel is formed between the expansion valve outlet interface 64 and the cooler inlet interface 65, and a third channel is formed between the cooler outlet interface 66 and the compressor inlet interface 67, so that the refrigerant enters the expansion valve 50 from the outlet of the liquid storage dryer 40 through the first flow channel, enters the battery cooler 30 from the outlet of the expansion valve 50 through the second flow channel, and enters the compressor 10 from the outlet of the battery cooler 30 through the third flow channel.

[0056] See also Figure 8 It should be noted that the flow channel inside the flow channel plate 60 is a straight hole structure, the bends of each of the flow channels are arc transitions, and anti-heat-crossing grooves 68 are provided between each of the flow channels. Specifically, the flow channel adopts a straight hole structure, which can be adapted to a variety of molding methods, including but not limited to machining, die-casting and other processes. After the internal flow channel is formed, the peripheral opening of the flow channel can be sealed by local welding. This flexibility provides more options for production. The most suitable molding process can be selected according to actual needs and conditions to improve production efficiency and reduce costs. The arc transition is adopted at the bends of each flow channel, which can effectively reduce the flow resistance of the refrigerant in the flow channel, thereby improving the circulation efficiency of the entire refrigerant circuit and improving the system performance. Anti-heat-crossing grooves 68 are provided between each flow channel to isolate refrigerant pipelines in different temperature zones and reduce heat-crossing phenomena, so as to ensure that the refrigerant maintains a relatively stable temperature state in each pipeline, thereby improving the circulation efficiency of the refrigerant and further improving the energy efficiency of the system. The design of the flow channel inside the flow channel plate 60 comprehensively considers multiple aspects such as refrigerant flow, heat transfer, and molding process, and improves the stability and reliability of the system by optimizing the flow channel structure and layout.

[0057] Also, continue reading Figure 8, the flow channel in the flow channel plate 60 connected to the inlet of the expansion valve 50 is a straight-through structure. This design can avoid the refrigerant passing through one or two bends before entering the valve seat structure of the expansion valve 50. This design significantly reduces the flow resistance of the refrigerant in the flow channel, allowing the refrigerant to enter the expansion valve 50 more smoothly, thereby improving the circulation efficiency of the refrigerant circuit. The design of the straight-through flow channel helps to ensure that the refrigerant can be stably and continuously supplied to the expansion valve 50. Due to the lack of flow obstruction caused by the bend, the flow velocity and flow rate of the refrigerant in the flow channel are more uniform, thereby ensuring that the expansion valve 50 can obtain a stable and sufficient supply of refrigerant and achieve precise flow control. The design of the straight-through flow channel helps to ensure that the refrigerant can be stably and continuously supplied to the expansion valve 50. Due to the lack of flow obstruction caused by the bend, the flow velocity and flow rate of the refrigerant in the flow channel are more uniform, thereby ensuring that the expansion valve 50 can obtain a stable and sufficient supply of refrigerant and achieve precise flow control.

[0058] Also, see Figure 8 and Fig. 9 The compressor inlet interface 67 in the flow channel plate 60 connected to the compressor inlet 12 is arranged at the lowest point of the refrigerant circuit integrated module pipeline, so that the flow direction of the low-pressure side refrigerant is from top to bottom. This flow direction avoids the need for the refrigerant to climb against gravity, reduces the flow resistance, and allows the refrigerant to enter the compressor 10 more smoothly, which can effectively ensure the oil return rate of the refrigerant circuit integrated module. The optimized refrigerant flow direction and oil return efficiency help to improve the performance of the entire refrigerant circuit integrated module, and the refrigerant can circulate more efficiently to achieve a faster and more stable cooling effect. In addition, since the compressor inlet interface 67 is located at the lowest point of the pipeline, maintenance personnel can approach and operate more conveniently during inspection and maintenance, reducing the difficulty and cost of maintenance.

[0059] See also Figure 1 , Figure 5 and Fig. 9It can be understood that the refrigerant circuit integrated module also includes a sensor assembly, and the sensor assembly includes a temperature sensor 71 and a temperature and pressure sensor 72. The temperature sensor 71 is arranged at the outlet of the liquid storage dryer 40, and the temperature and pressure sensor 72 is respectively arranged at the inlet 12 of the compressor and the outlet 13 of the compressor. Specifically, in this embodiment, a second sensor installation port 691 for installing the temperature sensor 71 is provided on the flow channel plate 60 adjacent to the outlet of the liquid storage dryer 40. By arranging the temperature sensor 71 at the outlet of the liquid storage dryer 40, the temperature state of the refrigerant when it flows out of the liquid storage dryer 40 can be monitored in real time. By monitoring the refrigerant temperature at the outlet of the liquid storage dryer 40, potential problems such as insufficient refrigerant flow, overheating or overcooling can be discovered in time. A first sensor mounting port 14 is provided at the outlet 13 adjacent to the compressor, and a third sensor mounting port 692 is provided at the inlet 12 adjacent to the compressor on the flow channel plate 60. The first sensor mounting port 14 and the third sensor mounting port 692 are respectively used to install a temperature and pressure sensor 72. By providing the temperature and pressure sensors 72 at the inlet 12 adjacent to the compressor and the outlet 13 of the compressor, the temperature and pressure changes at the inlet and outlet of the compressor 10 can be monitored in real time. This helps to understand the working status of the compressor 10, such as whether it is overloaded, whether there is leakage, and other problems. By analyzing these data, real-time monitoring and optimization of the performance of the compressor 10 can be achieved to ensure efficient operation of the system. The real-time data provided by the sensor assembly can provide an important basis for fault diagnosis of the system. When a system failure occurs, the problem can be quickly located by analyzing the sensor data, and corresponding measures can be taken to repair it.

[0060] See also Figure 1 It should be noted that the refrigerant circuit integrated module also includes an electronic connector 80, which is arranged in the space enclosed by the compressor 10 and the battery cooler 30. Specifically, this arrangement is conducive to making the various electronic connectors 80 face roughly the same direction, the vehicle wiring harness is easy to install, and will not occupy additional space in the vehicle, which is conducive to the layout of the vehicle, making the interior space of the vehicle more compact and efficient; and, the various electronic connectors 80 are arranged in a centralized manner, which can reduce the overall length of the wiring harness. The shorter wiring harness not only reduces the material cost, but also reduces the signal attenuation and interference problems that may be caused by the excessive length of the wiring harness, and improves the stability and reliability of the electrical system. By reducing the length of the wiring harness and simplifying the installation process, the manufacturing cost of the vehicle can be reduced to a certain extent.

[0061] Based on the same concept, the present application also provides a vehicle thermal management system, including the above-mentioned refrigerant circuit integrated module. In this way, the vehicle thermal management system can effectively improve space utilization, facilitate vehicle layout, optimize the connection structure, reduce the number of pipeline connections, and effectively reduce the hidden dangers of refrigerant leakage.

[0062] In summary, the refrigerant circuit integrated module and vehicle thermal management system provided by the utility model can effectively improve space utilization and facilitate vehicle layout; optimize the connection structure, reduce the number of pipe connections, and effectively reduce the hidden dangers of refrigerant leakage; shorten the pipe connection length, reduce the circuit pressure drop and cross-heat, and effectively improve the system performance; the component layout and structural design are reasonable, which can effectively improve the safety performance of the R290 refrigerant thermal management system.
