Description

Technical Field

[0001] This utility model relates to the field of vehicle thermal management technology, and in particular to an integrated thermal management structure for an evaporator and a compressor. Background Technology

[0002] As new energy vehicles increasingly demand higher levels of integration, safety, and adaptability to extreme operating conditions in their thermal management systems, the limitations of traditional integrated thermal management structures are becoming more and more apparent, necessitating breakthroughs in performance through innovation in the connection methods of key components.

[0003] Existing integrated thermal management systems typically achieve thermal management goals through secondary heat exchange via a refrigerant system and an external water system. They mainly consist of four components—compressor, condenser, expansion valve, and evaporator—mounted together on a single base plate. Most systems use LCC plate heat exchangers as condensers and Chiller plate heat exchangers as evaporators. The LCC and Chiller plate heat exchangers provide cold and heat sources to external thermal units via the water side. These external thermal units then connect to the heat or cold source according to a control strategy to achieve the desired thermal piping goals.

[0004] like Figure 11 As shown, the compressor 02 currently has an intake port 021 at its top, and the Chiller plate heat exchanger 01 has a liquid refrigerant inlet 011 and a gaseous refrigerant outlet 012. During operation, the refrigerant enters the liquid refrigerant inlet 011 of the Chiller plate heat exchanger 01 through pipe 03. Inside the Chiller plate heat exchanger 01, the refrigerant absorbs heat through evaporation and becomes a superheated gaseous state, which is then discharged from the gaseous refrigerant outlet 012. The gaseous refrigerant then enters the intake port 021 of the compressor 02 through pipe 04 to complete the entire cycle.

[0005] The evaporator and compressor suction port are connected by a pipeline. This connection is redundant, resulting in a high risk of leakage. The extensive use of pipelines and joints multiplies the number of system interfaces. Especially for flammable refrigerants such as R290, even a small leak can cause a safety hazard. Traditional structures cannot reduce this risk through connection methods. Moreover, this solution has low integration efficiency. The distributed pipeline connection results in a scattered component layout, a large overall system size, occupies limited installation space in the vehicle, and increases assembly processes and costs. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an integrated thermal management structure for an evaporator and a compressor. This integrated thermal management structure can reduce the risk of refrigerant leakage, improve heat exchange efficiency, reduce size, and is easy to disassemble and maintain, effectively meeting the needs of new energy vehicles.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An integrated thermal management structure for an evaporator and a compressor includes an evaporator and a compressor body, wherein the evaporator has a gaseous refrigerant outlet; characterized in that it further includes a connecting structure; the compressor body has a low-pressure cover, one side of which has an electrical cover, and the low-pressure cover has an air intake port that connects to a refrigerant cavity inside the compressor body; the gaseous refrigerant outlet of the evaporator corresponds to the air intake port of the low-pressure cover; the connecting structure passes through the electrical cover, and the gaseous refrigerant outlet of the evaporator is fixedly connected to the air intake port of the low-pressure cover through the connecting structure.

[0008] The evaporator described above uses a Chiller plate heat exchanger.

[0009] The aforementioned electrical cover protects the internal electrical components of the compressor from external moisture, dust, oil, and other contaminants, ensuring stable operation of electrical insulation and control systems, and forming a physical barrier to prevent maintenance personnel from accidentally touching high-voltage circuits.

[0010] The aforementioned integrated thermal management structure directly establishes a pathway between the compressor's suction port and the evaporator's gaseous refrigerant outlet through a connection structure, eliminating the connecting pipes between the two in traditional structures. This allows the compressed, high-temperature, high-pressure refrigerant to directly enter the evaporator for evaporation and heat absorption. The entire structure significantly reduces the number of redundant pipes and joints, lowering the risk of leakage from flammable refrigerants such as R290 at the connection source and improving system safety. Furthermore, it shortens the refrigerant transmission path, reducing energy and heat loss caused by flow resistance, improving the heat exchange efficiency of the thermal management system, and exhibiting strong low-temperature adaptability. Simultaneously, it simplifies the overall structural layout, reduces the system's footprint, and is suitable for the compact installation environment of new energy vehicles.

The first locking elements then secure the evaporator to the outer wall of the low-pressure cover, ensuring that the gaseous refrigerant outlet and the intake port always maintain a tight fit. Even under vibration conditions during vehicle operation, structural stability is maintained, preventing leakage gaps due to loosening. The detachable connection method facilitates disassembly and replacement of components during later maintenance.

[0026] Example 1, such as Figure 1-2 As shown, the integrated thermal management structure of the evaporator and compressor in this embodiment includes an evaporator 1, a compressor body 2, and a connecting structure 3. The evaporator 1 is provided with a gaseous refrigerant outlet 11, and the compressor body 2 is provided with a low-pressure cover 21. An electrical cover 22 is provided on one side of the low-pressure cover 21. The low-pressure cover 21 has an air intake 211 that connects to the refrigerant cavity inside the compressor body 2. The gaseous refrigerant outlet 11 of the evaporator 1 corresponds to the air intake 211 of the low-pressure cover 21. The connecting structure 3 passes through the electrical cover 22, and the gaseous refrigerant outlet 11 of the evaporator 1 is fixedly connected to the air intake 211 of the low-pressure cover 21 through the connecting structure 3.

[0027] The evaporator 1 mentioned above uses a Chiller plate heat exchanger.

[0028] The aforementioned integrated thermal management structure directly establishes a pathway between the compressor suction port 211 and the gaseous refrigerant outlet 11 of the evaporator 1 through the connection structure 3, eliminating the connecting pipe between the two in the traditional structure. This allows the compressed high-temperature and high-pressure refrigerant to directly enter the evaporator 1 for evaporation and heat absorption. On the one hand, the entire structure significantly reduces the number of redundant pipes and joints, reducing the risk of leakage of flammable refrigerants such as R290 from the connection source and improving system safety. On the other hand, it shortens the refrigerant transmission path, reduces energy loss and heat loss caused by flow resistance, improves the heat exchange efficiency of the thermal management system, has strong low-temperature adaptability, and simplifies the overall structural layout, reduces the system's footprint, and is suitable for the compact installation environment of new energy vehicles.

[0029] The connecting structure 3 includes a circular sleeve 31 and a plurality of first locking elements 32. The electrical cover 22 is provided with a first through hole 221 and a plurality of second through holes 222. The first through hole 221 corresponds to the gaseous refrigerant outlet 11 and the suction port 211. The circular sleeve 31 is located in the first through hole 221, and the gaseous refrigerant outlet 11 is connected to the suction port 211 through the circular sleeve 31. Each first locking element 32 is located in the corresponding second through hole 222, and the outer wall of the evaporator 1 is in close contact with the outer wall of the low-pressure cover 21 through each first locking element 32. The aforementioned gaseous refrigerant outlet 11 is connected to the intake port 211 via the circular sleeve 31, achieving initial positioning and rapid connection of the passage, thus improving assembly efficiency. The first locking member 32 then secures the outer wall of the evaporator 1 and the low-pressure cover 21, ensuring that the gaseous refrigerant outlet 11 and the intake port 211 remain in a tight fit through the circular sleeve 31. Even under vibration conditions during vehicle operation, structural stability can be maintained, preventing leakage gaps caused by loosening. At the same time, the detachable connection method facilitates the disassembly and replacement of components during later maintenance.

The circular sleeve 31 is inserted into the suction port 211. In a more preferred embodiment, the first port 311 of the circular sleeve 31 is integrally connected to the outer wall of the evaporator 1. By using this method in conjunction with each of the first locking members 32, a dual connection structure 3 of insertion positioning and locking fixation can be formed.

The first sealing ring 4 can block the path of refrigerant leakage from the mating gap between the evaporator 1 and the low-pressure cover 21, further improving the sealing performance.

[0032] The first locking element 32 uses a first bolt 321. Multiple third through holes 12 are formed on the outer wall of the evaporator 1, and multiple first screw holes 212 corresponding to the third through holes 12 are formed on the outer wall of the low-pressure cover 21. The number of first bolts 321, first through holes 221, first screw holes 212, and second through holes 222 are the same and correspond one-to-one. The shank of the first bolt 321 passes through the corresponding third through hole 12 and second through hole 222 in sequence and is threaded into the first screw hole 212. Typically, the third through holes 12 are evenly distributed on the outer wall of the evaporator 1. Tightening the first bolt 321 presses the outer wall of the evaporator 1 against the outer walls of the electrical cover 22 and the low-pressure cover 21, ensuring that the preload between the evaporator 1 and the electrical cover 22 and the low-pressure cover 21 meets the requirements of vibration conditions and prevents loosening after long-term use. The distribution design of multiple bolts can balance the pressure on the contact surface and prevent component deformation caused by local stress concentration. At the same time, the detachability of the bolt connection facilitates the maintenance and replacement of the evaporator 1 or the compressor in the future, reducing maintenance costs and operating difficulties.
