DETAILED DESCRIPTION

[0021] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0022] like Figure 1 and Figure 2 As shown, the thermal management integrated module structure suitable for R290 refrigerant has a coolant assembly on the coolant substrate 1 and a refrigerant assembly on the refrigerant substrate 2; the refrigerant assembly includes a compressor 3, and the compressor 3 is arranged at one end of the refrigerant substrate 2.

[0023] As the core component of the thermal management system, the compressor 3 is integrated on the refrigerant substrate 2, which can improve the operating efficiency of the thermal management system, make the thermal management system have a faster response and lower energy consumption, ensure operational reliability, reduce the number of pipelines and components, reduce the volume, and save space for vehicle layout.

[0024] The thermal management integrated module fixes the compressor 3, liquid storage tank 4, three-way water valve 9, water pump 8, multi-way water valve 7, water-cooled condenser 5, and chiller 6 together through the coolant substrate 1 and the refrigerant substrate 2, wherein the coolant substrate 1 and the refrigerant substrate 2 are fixed to each other, and the internal flow channels of the two substrates are effectively insulated through the topological structure and the hollow structure to prevent heat from being generated between circuits of different temperatures and mixed heat, resulting in failure of thermal management performance. The refrigerant circuit connects the refrigerant side components through the first pipeline 13, the second pipeline 14 and the internal flow channel of the refrigerant substrate 2 to form a complete closed loop, reducing the length and complexity of the refrigerant circuit, which effectively avoids the leakage and secondary filling of R290 refrigerant and reduces the risk of flammability. The thermal management solution of the whole vehicle achieves the thermal management requirements of the whole vehicle through heat exchange between the coolant and the refrigerant inside the integrated module.

[0025] like Figure 1As shown, the other end of the refrigerant substrate 2 is provided with a water-cooled condenser 5, a liquid storage tank 4 and a cooler 6; the compressor 3 and the refrigerant substrate 2 are connected with a first pipeline 13, and the compressor 3 and the water-cooled condenser 5 are connected with a second pipeline 14. The refrigerant substrate 2 integrates the above components into one, replaces the traditional intercommunication pipeline with the internal flow channel of the substrate, reduces the number of brackets and pipelines, and reduces the assembly workload. Through the integrated setting of the above components, the failure rate of the component electronic control can be greatly reduced, which is convenient for periodic maintenance. The water-cooled condenser 5, the liquid storage tank 4 and the cooler 6 are concentrated at one end of the refrigerant substrate 2, making full use of the side space of the refrigerant substrate 2, which is conducive to reducing the design length and width of the refrigerant substrate 2, thereby reducing the overall volume. The refrigerant passes through the compressor 3, the water-cooled condenser 5, the liquid storage tank 4 and the cooler 6 in turn, and then returns to the compressor 3 to form a refrigerant circuit. In the above cycle process, the heat exchange process with the coolant is completed. In addition to the flow paths of the first pipeline 13 and the second pipeline 14, the refrigerant is connected to the above components through the internal flow channel of the refrigerant substrate 2.

[0026] like Figure 2 As shown, the coolant assembly includes a multi-way water valve 7, a three-way water valve 9 and a water pump 8, and the water pump 8 is located between the multi-way water valve 7 and the three-way water valve 9. A flow channel is arranged inside the coolant substrate 1 to communicate with the multi-way water valve 7, the three-way water valve 9 and the water pump 8 to realize the in and out, on and off and heat exchange of the coolant. The multi-way water valve 7 and the three-way water valve 9 are used to connect multiple thermal management components in the thermal management system of the whole vehicle, so as to control the on and off of different thermal management circuits. The water pump 8 is used to provide power for the flow of the coolant. The water pump 8 is arranged between the two water valves to facilitate the staggered arrangement of its plug-in ports.

[0027] like Figure 1 and Figure 2 As shown, the first bracket 11 is provided at the bottom of both sides of the refrigerant substrate 2, and steps 15 are provided at both ends of the top of the refrigerant substrate 2. The second bracket 12 is provided on the steps 15. The first bracket 11 and the second bracket 12 are both provided with a damping block 10, and a fixing hole 16 is provided in the middle of the damping block 10. The thermal management integrated module is connected to the whole vehicle through the damping block 10 as a whole, so as to achieve the NVH effect. The vibration caused by road excitation is absorbed by the buffering effect of the four damping blocks 10, and the influence of the traditional rigid connection on the stability of the thermal management integrated module is avoided. The two ends of the top of the refrigerant substrate 2 are treated with the step 15 structure, which can reduce the space occupied by the second bracket 12 on the top of the refrigerant substrate 2. The fixing hole 16 installs the damping block 10 on the vehicle body through the connecting piece to form a soft connection with the vehicle body. Among them, the axis of the damping block 10 on the first bracket 11 is parallel to the side of the refrigerant substrate 2, and the axis of the damping block 10 on the second bracket 12 is perpendicular to the refrigerant substrate 2, that is, the damping blocks 10 at the upper and lower parts of the refrigerant substrate 2 form two connection directions, which is conducive to improving the installation stability of the overall structure. The second bracket 12 is a planar structure, and convex ribs are arranged on the edges of both sides thereof to enhance the connection strength.

[0028] like Figure 2 As shown, the multi-way water valve 7 is arranged in the middle of the coolant substrate 1, and the three-way water valve 9 is located at both ends of the coolant substrate 1. Installing the multi-way water valve 7 in the middle of the coolant substrate 1 is convenient for the arrangement of the connecting pipelines and reduces the spatial interference effect on the surrounding components. Installing the three-way water valve 9 at both ends of the coolant substrate 1 can further reduce the layout space occupied by the valve body, and at the same time facilitate the misalignment of the pipelines connected to it and the pipelines connected to the multi-way water valve 7, thereby reducing the occupation of the layout space and making the pipeline distribution more reasonable. Among them, the outlet ends of the two three-way water valves 9 are embedded in the coolant substrate 1, and are respectively facing the two sides of the coolant substrate 1, which not only achieves the effect of reducing the number of fixed brackets used, but also avoids the interference effect of the pipelines of the two three-way water valves 9 in space.

[0029] like Figure 1 and Figure 2 As shown, the coolant substrate 1 and the refrigerant substrate 2 are arranged in parallel. In the above structure, the refrigerant assembly and the coolant assembly are separated by the above two substrates, reducing the heat radiation effect of the refrigerant circuit and the coolant circuit. The two parallel substrates are convenient for the whole module to be installed in a vertical and stable posture in the vehicle body, and both substrates are plate-shaped structures with uniform thickness, which are convenient for relative arrangement, reduce processing and molding costs, and can also provide a stable installation position for the components on the substrate.

[0030] like Figure 1 and Figure 2 As shown, the refrigerant assembly is arranged outside the refrigerant base plate 2, and the coolant assembly is arranged outside the coolant base plate 1. The coolant assembly and the refrigerant assembly are arranged on the sides of the two base plates respectively, which will not occupy the space at the outer edge of the base plate, will not significantly increase the overall volume of the module, and is conducive to providing space for other components in the vehicle body. At the same time, the connection ends of the pipes connected to the components are in opposite directions, the spatial interference effect is reduced, and the difficulty of assembly operation can be reduced when laying out the pipes.

[0031] like Figure 1 and Figure 2 As shown, the ends of the first bracket 11 and the second bracket 12 are provided with openings 17, and the shock absorbing block 10 is clamped in the opening 17. The shock absorbing block 10 is installed with the bracket in a clamping installation form, and is fastened to the vehicle body using a connecting piece to form a soft connection. The shock absorbing block 10 is not easy to fall out, and the assembly and disassembly process of the shock absorbing block 10 for later replacement is convenient, thereby improving efficiency.

[0032] like Figure 2 As shown, the water pumps 8 are arranged in pairs. Arranging multiple water pumps 8 increases the flow rate of the coolant, improves the corresponding speed of thermal management, and helps the circulation and heat dissipation process of the coolant, thereby adjusting the operating temperature of the automobile engine, battery, air conditioner and other components, preventing overheating, and maintaining a suitable operating temperature range.

[0033] A vehicle, including the above-mentioned thermal management integrated module structure suitable for R290 refrigerant. In a vehicle adopting the above-mentioned integrated solution in which all thermal management components are connected and fixed to each other, the heat exchange of the refrigerant in its internal thermal management system is mainly carried out on the thermal management integrated module, and the refrigerant and coolant sides are respectively connected through a base plate, and the circulation loop of the R290 refrigerant is used to form an independent closed loop, without the need for refilling, eliminating the safety hazard caused by its flammable characteristics when it is refilled and leaked. Compared with existing vehicles, it has the advantages of fewer thermal management components and connecting pipes, low cost, and simple layout space.

[0034] The thermal management integrated module structure suitable for R290 refrigerant integrates the thermal management components. Compared with the traditional thermal management components, it adopts an integrated refrigerant base plate 2 and a coolant base plate 1, reduces the connecting pipes between the components, effectively reduces the number of brackets and connecting pipes, reduces the weight of the whole vehicle, has the advantages of lightweight, low cost, and integration, makes the overall layout more compact, saves the space of the whole vehicle, improves the space utilization rate of the whole vehicle, and reduces the weight. The compressor 3 is synchronously integrated into the thermal management integrated module, and the refrigerant circuit forms an independent integrated closed loop, which effectively reduces the risk of flammability caused by leakage of R290 refrigerant and ensures the safety of the vehicle. The thermal management integrated module and the whole vehicle adopt an integral soft connection, and the NVH performance is reliable.

Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
