Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to an integrated structure of a compressor, water pump and heat exchanger for use in new energy vehicles. Background Technology

[0002] New energy special vehicles refer to non-passenger vehicles that use electric drive systems and are specifically designed for specific purposes. In existing vehicle technology, compressors, electric water pumps, and heat exchangers are the core components of the thermal management system. These key components are mostly installed separately on the vehicle chassis or body structure, and are connected to each other through multiple refrigerant and coolant lines. This not only results in a dispersed structure and large space occupation, but also inconveniences in assembly, maintenance, and system sealing control.

[0003] However, in new energy special vehicles, due to the relatively compact body structure and dense configuration of functional equipment, the space available for arranging the thermal management system is extremely limited. The thermal management solutions used in traditional passenger cars are difficult to adapt to the compactness, modularity, and high reliability requirements of new energy special vehicles.

[0004] To address the aforementioned issues, there is an urgent need for a compact and highly integrated integrated structure for compressors, water pumps, and heat exchangers used in new energy vehicles, in order to meet the miniaturization and high-efficiency integration requirements of thermal management systems for new energy special vehicles. Summary of the Invention

[0005] This utility model addresses the shortcomings of existing technologies by proposing an integrated structure for a compressor, water pump, and heat exchanger used in new energy vehicles. The specific technical solution is as follows:

[0006] To better realize this utility model, it can be further made as follows:

[0007] The beneficial effects of this utility model are as follows:

[0008] First, the overall structure is simple and compact. By integrating the compressor assembly, electric water pump and heat exchanger onto the same mounting bracket and supporting them on the base plate, the compactness of the system structure is significantly improved. This overcomes the problem of separate distribution and complex connection of components in traditional thermal management systems, thereby saving cabin layout space and making it suitable for new energy special vehicles with structural constraints.

[0009] Secondly, by arranging the compressor assembly and heat exchanger at opposite ends of the mounting bracket and placing the electric water pump between them, the thermal management path is optimized, which helps to minimize the refrigerant flow and coolant circulation paths, reduce energy loss, and improve heat exchange efficiency.

[0010] Third, by constructing the mounting bracket into a structure that includes a U-shaped support plate and a connecting plate, and by using bolts to achieve a detachable connection, the rigidity and modular maintainability of the overall structure are improved, which is beneficial for the replacement and installation of the compressor and other components.

[0011] By setting a support shaft that runs horizontally through a U-shaped support plate on the compressor assembly and fixing it with bolts, the heat exchanger and the electric water pump are fixed to independent first and second support frames respectively, and connected to the connecting plate and the base plate. This achieves stable installation of heavy-duty equipment, effectively absorbs vibration during compressor operation, and reduces vibration coupling effect between components, thereby enhancing the system's anti-interference capability.

[0012] Fourth, by installing a water temperature sensor on the coolant outlet pipe and a temperature and pressure sensor on the inlet pipe, real-time monitoring of the system's operating status can be achieved, enhancing intelligent control capabilities and ensuring stable operation of the system under various working conditions.

[0013] Fifth, by using rigid metal pipes as the refrigerant connection pipes and coolant inlet and outlet pipes, the strength and pressure resistance of the piping system are improved, reducing deformation and leakage problems during long-term use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] This implementation example Figures 1 to 4 As shown, an integrated structure for a compressor, water pump, and heat exchanger used in new energy vehicles is provided. The integrated structure includes a base plate 1, a mounting bracket 6, a compressor assembly 2, an electronic water pump 3, a heat exchanger 4, an electronic expansion valve assembly 5, a refrigerant connection pipe 9, a coolant inlet pipe 10, and a coolant outlet pipe 11.

[0022] The mounting bracket 6 is elastically supported on the base plate 1 by a plurality of shock-absorbing pads 19, which are preferably elastic washers made of rubber composite material, for absorbing vibration and impact.

[0023] The mounting bracket 6 includes a U-shaped support plate 7 and a connecting plate 8. The U-shaped support plate 7 is integrally formed and bent from a base plate and two side walls. One end of the connecting plate 8 is fixedly connected to one side wall of the U-shaped support plate 7 by bolts, and is used to support the heat exchanger 4.

[0024] The compressor assembly 2 has two parallel support shafts 13 at its bottom. The support shafts 13 pass through the two opposite side walls of the U-shaped support plate 7 laterally and are fixedly connected to the threaded holes of the corresponding side walls by bolts to achieve stable positioning of the compressor assembly 2. The support shafts 13 are preferably solid shafts made of galvanized steel.

[0025] The heat exchanger 4 is fixedly installed on the first support frame 14, which is bolted to the outside of the connecting plate 8.

[0026] The electronic water pump 3 is located between the compressor assembly 2 and the heat exchanger 4. The electronic water pump 3 is mounted on the second support frame 15, which is fixedly connected to the base plate 1.

[0027] The electronic water pump 3 is bolted to the top of the second support frame 15. The inlet of the electronic water pump 3 is connected to the first connector 18. The outlet of the electronic water pump 3 is connected to the coolant inlet of the heat exchanger 4 through the coolant inlet pipe 10. The inner end of the coolant outlet pipe 11 is connected to the coolant outlet of the heat exchanger 4 to guide the coolant circulation.

[0028] An electronic expansion valve assembly 5 is installed on the heat exchanger 4. The refrigerant inlet of the electronic expansion valve assembly 5 is connected to the refrigerant outlet of the compressor assembly 2 via a refrigerant connecting pipe 9. The refrigerant outlet of the electronic expansion valve assembly 5 is directly connected to the refrigerant inlet of the heat exchanger 4. The electronic expansion valve assembly 5 has a connecting cavity inside. One end of the connecting cavity is directly connected to the refrigerant outlet of the heat exchanger 4, and the other end is connected to a return pipe 12. The return pipe 12 can be connected to the suction port of the compressor assembly 2 through a connecting pipe, so that low-pressure gaseous refrigerant can be guided to the suction port of the compressor assembly 2.

[0029] In this embodiment, a water temperature sensor 16 is installed on the coolant outlet pipe 11 to detect the coolant temperature in real time and feed it back to the vehicle thermal management controller. A temperature and pressure sensor 17 is installed on the coolant inlet pipe 10 to detect the state of the coolant entering the heat exchanger 4, so as to assist in accurately adjusting the flow output of the electronic water pump 3 to match the system load.

[0030] Preferably, the refrigerant connection pipe 9, the coolant inlet pipe 10, and the coolant outlet pipe 11 all adopt a metal rigid pipe structure. The metal material is preferably aluminum alloy or stainless steel, which has strong pressure resistance and thermal stability and is suitable for the vehicle operation requirements under complex working conditions.

[0031] The working principle is explained as follows: In the integrated structure of this embodiment, the high-pressure refrigerant output from the compressor assembly 2 is sent to the electronic expansion valve assembly 5 through the refrigerant connection pipe 9 for throttling and pressure reduction. The refrigerant directly enters the heat exchanger 4 from the refrigerant outlet of the electronic expansion valve assembly 5 to exchange heat with the coolant, thereby achieving coolant cooling. The cooled refrigerant returns to the suction port of the compressor assembly 2 through the connecting cavity, return pipe 12, and pipeline, forming a closed refrigeration cycle.

[0032] Meanwhile, the electric water pump 3 sends external coolant into the heat exchanger 4 through the coolant inlet pipe 10, and after cooling, it is output to other components of the system through the coolant outlet pipe 11, realizing the coordinated control of the vehicle's thermal management function.

[0033] This structure, through the highly integrated layout of the compressor, water pump and heat exchanger, effectively improves space utilization efficiency and modular assembly convenience, making it particularly suitable for use in space-constrained new energy special vehicles.
