[0015] In an optional embodiment, the mounting structure includes a buckle, and the buckle is used for detachable snap-fitting with the frame.

[0016] Based on the above solution, the buckle is directly integrated on the shell, and no additional components are required to connect the shell and the frame, which simplifies the assembly process and reduces costs.

[0043] In the prior art, the automotive thermal management module includes multiple components, such as the HAVC assembly 200, the cooling module 300, the thermal management integrated module 400, the compressor 500, the water heating module 600 and the liquid storage tank 700. During assembly, the multiple components are arranged on the frame according to the layout of the whole vehicle. In this way, basically each component needs to be designed with a corresponding installation position and a corresponding installation structure. There are many processes when assembling the thermal management module with the frame, and the assembly efficiency is low. In addition, multiple components are assembled independently, and are affected by the structural design of the frame, and there is a large distance between them, which leads to a large volume of the entire thermal management module and a large space occupied.

[0044] In view of this, the designer provides a vehicle thermal integration system, which can improve the compactness of the overall structure, reduce the space required for assembly, shorten the distance between multiple components, save materials, and reduce operating costs; at the same time, it can reduce the difficulty of assembly with the frame and improve assembly efficiency.

[0045] Please combine Figure 1 and Figure 2In this embodiment, the vehicle thermal integration system includes a housing 100 and a HAVC assembly 200, a cooling module 300, a thermal management integrated module 400, a compressor 500, a water heating module 600 and a liquid storage tank 700, all of which are installed in the housing 100. The housing 100 is provided with a mounting structure, and the mounting structure is used to connect with the vehicle frame; the housing 100 is provided with an air inlet 101 and an air outlet 102 that match the HAVC assembly 200, and the housing 100 is provided with a water heating module 600 and a thermal management integrated module 400. The HAVC assembly 200 cooperates with the cooling module 300, and the compressor 500 is arranged on the connecting pipeline between the cooling module 300 and the HAVC assembly 200, and a gas-liquid separator 900 cooperating with the compressor 500 can be arranged on the pipeline; the thermal management integrated module 400 is used to cool or heat the battery pack, the drive motor and other components that require heat exchange, the water heating module 600 is connected to the liquid storage tank 700, and the water heating module 600 is used to heat the battery pack and the passenger compartment and other components that require heating.

[0046] Based on the above, the working principle of the vehicle thermal integration system provided in this embodiment is as follows:

[0047] By integrating the HAVC assembly 200, cooling module 300, thermal management integrated module 400, compressor 500, water heating module 600 and liquid storage tank 700 in the housing 100, the pipes and wiring harness materials connecting the various components are reduced or saved, and the heat loss and electrical loss are reduced, and the amount of cooling media such as air conditioning refrigerant and antifreeze is reduced. Since the various components are integrated into a module, the overall structure is compact, the volume is small, and the space occupied by the whole vehicle is small, which is conducive to the design of the whole vehicle. In addition, multiple components are installed in the housing 100, and most of the components do not participate in the coordination of the whole vehicle. It is only necessary to connect the housing 100 directly to the frame. The structural design of the whole vehicle is simple, and the internal components are highly interchangeable.

[0048] The following embodiments illustrate the details of the vehicle thermal integration system provided in this application by way of examples.

[0049] In this embodiment, the mounting structure optionally includes a mounting lug, and a fixing hole for a bolt to pass through is provided on the mounting lug; the mounting lug is used to be fixed to the frame by bolts. The mounting lug is fixed to a corresponding position on the frame by bolts, and the position of the housing 100 relative to the frame is accurate, and the installation is convenient and the assembly efficiency is high.

[0050] It should be understood that the number of mounting lugs is set as needed, and a plurality of mounting lugs of a corresponding number and arrangement can be set according to the structure of the frame, thereby improving the firmness of the connection between the housing 100 and the frame.

[0051] In this embodiment, optionally, the fixing hole is configured as a waist-shaped hole.

[0052] With such a design, after the bolt is passed through the fixing hole on the mounting lug, due to certain errors in manufacturing and assembly, it is necessary to fine-tune the position of the housing 100 relative to the frame. At this time, the bolt can slide relative to the fixing hole to adaptively adjust the position, so that after the position of the housing 100 relative to the frame is adjusted, it can also be ensured that the bolt is aligned with the threaded hole on the frame, and the assembly is flexible and convenient.

[0053] It should be understood that in other embodiments, the mounting structure may optionally include a buckle, which is used for detachable engagement with the frame. The buckle is directly integrated on the housing 100, and no additional components are required to connect the housing 100 and the frame, thereby simplifying the assembly process and reducing costs.

[0054] It is worth noting that the buckle can be a structure with multiple inverted fits, which can improve stability.

[0055] In this embodiment, optionally, a heat-insulating layer is provided on the inner wall surface of the housing 100. Multiple components are integrated in the housing 100, and the heat-insulating layer provided in the housing 100 can play a role in heat preservation, so that the multiple components are operated in a better temperature environment, and the operation is stable and reliable. The heat-insulating layer can be bonded and fixed on the inner wall surface of the housing 100.

[0056] In this embodiment, optionally, a noise reduction layer is provided on the inner wall surface of the housing 100. Multiple components are located in the housing 100. After the noise reduction layer is provided on the housing 100, some noise generated when the components are operated can be eliminated. The noise reduction layer can be bonded and fixed on the inner wall surface of the housing 100.

[0057] It should be understood that the heat-insulating layer and the noise-reducing layer can be provided on the inner wall surface of the outer shell 100 at the same time, so that the outer shell 100 has the functions of heat-insulating and noise-reducing at the same time.

[0058] In this embodiment, the housing 100 optionally has an equipment cavity, and the equipment cavity has an open state and a closed state that can be switched to each other. The HAVC assembly 200, the cooling module 300, the thermal management integrated module 400, the compressor 500, the water heating module 600 and the liquid storage tank 700 are all located in the equipment cavity. The equipment cavity can be opened to facilitate the disassembly and assembly of parts and the maintenance, and the operation is convenient. When the vehicle thermal integration system is in operation, the equipment cavity is closed, and external impurities are not easy to enter the equipment cavity. The operating environment of multiple parts is good, and the operation is more stable and reliable.

[0059] For example, in this embodiment, the housing 100 can be a split structure, and the housing 100 has a bottom shell and a top cover, and the top cover and the bottom shell cooperate to define a device cavity, and when the top cover is opened, it is equivalent to opening the device cavity. Components such as the HAVC assembly 200, the cooling module 300, the thermal management integrated module 400, the compressor 500, the water heating module 600 and the liquid storage tank 700 can be installed on the bottom shell.

[0060] In this embodiment, optionally, an illumination structure for adjusting the light in the device cavity is installed on the housing 100. When disassembling and assembling parts in the housing 100 in a scene with poor light, turning on the illumination structure can provide good lighting, making the operator's field of vision clearer, reducing the difficulty of operation, and improving the efficiency of disassembly and assembly.

[0061] It should be understood that the lighting structure can be an LED light strip or the like.

[0062] In this embodiment, the vehicle thermal integration system may further include an air duct 800, which is connected to the housing 100 and cooperates with the cooling module 300. When the cooling module 300 is in operation, the air outside the vehicle can be introduced into the cooling module and HVAC, so that the heat exchanger and the air can exchange heat, thereby preventing the hot air from running around and making the airflow on the surface of the heat exchanger more uniform and smooth, and preventing additional noise from being generated.

[0063] Optionally, the air guide cover 800 is connected to the housing 100 via a flange. The connection structure between the air guide cover 800 and the housing 100 is simple and easy to assemble.

[0064] It should be understood that the HAVC assembly 200, cooling module 300, thermal management integrated module 400, etc. can all refer to existing known structures. In order to avoid repeated descriptions, their components, connection relationships and working principles are not described in detail.

[0065] The vehicle thermal integration system provided in this embodiment has a compact structure, a small volume, and is easy to assemble. Multiple components are integrated together with a small distance between each other, saving installation pipes and other components, less consumables, and low cost. During assembly, it is only necessary to connect the housing 100 to the frame, which is convenient to connect. There is no need to set multiple mounting parts on the frame to match different components, which simplifies the frame structure and reduces processing costs.

[0066] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
