Description

Technical Field

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

[0002] The automotive thermal management integrated module (hereinafter referred to as the integrated module) is a component that integrates the structure or control of components such as pumps, valves, heat exchangers, sensors, water storage bottles, liquid storage tanks or gas-liquid separators, pipelines, etc. that are dispersedly arranged on the coolant side and refrigerant side of the thermal management system.

[0003] Some existing integrated modules integrate the coolant side or the refrigerant side separately, with a low degree of integration. A large number of pipes and other parts are still required to connect the refrigerant side and the coolant side, and the material cost and manufacturing cost of the whole vehicle are relatively high. Although another part of the integrated modules integrates the refrigerant side and the coolant side at the same time, it is inconvenient to disassemble the refrigerant side and the coolant side of the module into two sub-assemblies separately, and the structure or production of the refrigerant side flow plate or the coolant side flow plate is relatively complex, the assembly process of the integrated module is poorly flexible, and the manufacturing cost advantage is small.

[0004] At the same time, the existing integrated module vehicle installation points are often set on the coolant side flow plate (plastic material) or the refrigerant side flow plate (aluminum alloy material), and the reliability is relatively poor. When the installation boundary of the whole vehicle is adjusted, it is often necessary to newly develop the coolant side flow plate (plastic material) or the refrigerant side flow plate (aluminum alloy material). The versatility is poor, the parts cost advantage is small, and it is not conducive to platform development. Utility Model Content

[0088] Specifically, the sheet metal mounting bracket 16 is a square frame and is fixedly connected to the automotive thermal management integrated module by bolts, serving as a connection structure between the automotive thermal management integrated module and the entire vehicle. The automotive thermal management integrated module is fixedly installed on the entire vehicle through the connection between the sheet metal mounting bracket 16 and the entire vehicle.

[0089] by Figure 7 Taking the direction shown as an example, the refrigerant side upper flow channel plate 17 and the refrigerant side lower flow channel plate 18 are both fixedly mounted on the left end of the right side of the sheet metal mounting bracket 16, and the refrigerant side lower flow channel plate 18 is arranged at the lower end, and the refrigerant side upper flow channel plate 17 is arranged at the upper end, and the coolant side flow channel plate 5 is fixedly mounted on the left side of the sheet metal mounting bracket 16, and the battery cooler 11 and water-cooled condenser 12 and other components installed on the coolant side flow channel plate 5 pass through the center of the sheet metal mounting bracket 16, so that the coolant side integrated module 2, the refrigerant side integrated module 3 and the sheet metal mounting bracket 16 form an integrated automotive thermal management integrated module, and are installed on the vehicle through the mounting points on the sheet metal mounting bracket 16.

[0090] In another embodiment, a reserved installation hole 4 is further provided on the refrigerant-side downflow channel plate 18 to meet the installation requirements of other vehicle models on the platform (right-hand drive vehicles, etc.); the sheet metal mounting bracket 16 can also be set to other special-shaped structures to adapt to different installation positions and vehicle structure.

[0091] The above-mentioned installation and shock-absorbing structure for the automotive thermal management integrated module can be used to connect and assemble the two upper vehicle installation points during vehicle assembly by screwing the vehicle bolts from top to bottom into the first shaft sleeve 161 respectively arranged in the first shock-absorbing pad installation through hole K1 and the second shock-absorbing pad installation through hole K2 (under the tension of the vehicle bolts, the baffle of the first shaft sleeve 161 transmits the tension to compress the shock-absorbing pad 19), which can solve the problem that the vehicle cannot weld the installation nuts or the thermal management integrated module cannot be screwed in from bottom to top with the assembly bolts; and the use of closed circular holes as shock-absorbing pad installation through holes can make the shock-absorbing pad 19 more evenly compressed, thereby improving reliability;

[0092] The third shock-absorbing pad mounting hole K3 is designed with a flip-hole design, which can increase the contact area with the second sub-shock-absorbing pad 164, improve reliability and durability, and the second sub-shock-absorbing pad 164 is mounted on the flip-hole of the third shock-absorbing pad mounting hole K3 through a ring groove, which can effectively reduce the shaking distance of the lower mounting point in the front and rear directions, thereby improving product reliability and durability; when installing the lower mounting point, the vehicle bolts are directly screwed into the threaded holes provided at the vehicle mounting point from front to back (the direction of the first sub-shock-absorbing pad 163 toward the second sub-shock-absorbing pad 164).

[0093] In another embodiment, a vehicle thermal management system is also provided, including a thermal management device and an automotive thermal management integrated module. The thermal management device may include but is not limited to the vehicle thermal management system and also includes any one or more of an electric drive system, a battery pack, a front-end cooling module, HVAC, a compressor, and an air-conditioning pipeline. The electric drive system, battery pack, front-end cooling module, HVAC, a compressor, and air-conditioning pipelines are connected to corresponding interfaces on the automotive thermal management integrated module to connect with each thermal management device to form various flow paths and realize various preset modes of the vehicle thermal management system.

[0094] Furthermore, this embodiment also provides a vehicle, which includes the above-mentioned vehicle thermal management system.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
