Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted refrigeration equipment, specifically to integrated compressors and new energy vehicles. Background Technology

[0002] With the emergence of new refrigerants, R290 has become the preferred option among fourth-generation HFO refrigerants, and it has a very broad application market. However, due to its flammability, R290 has extremely stringent requirements for the system's leak prevention capabilities and safety.

[0003] CN208687899U introduces an air-cooled heat pump type modular air conditioning unit, which relates to the field of air conditioning equipment technology. It includes multiple air conditioning unit units connected by fasteners. Each air conditioning unit unit includes a base plate module, a control module, a compressor module, a coil heat exchange module, and a fan module. The control module and the compressor module are mounted on the base plate module. The coil heat exchange module is located above the compressor module. The fan module is located above the coil heat exchange module. It has the advantages of high modularity, convenient assembly, easy expansion, and strong versatility.

[0004] CN118478642A describes a modular air conditioning system for electric vehicles, configured as an integrated module to perform vehicle interior air cooling, vehicle interior air heating, and battery cooling. The modular air conditioning system includes: an instrument panel that divides the vehicle into an electrical and physical (PE) system compartment housing the vehicle's PE system and a passenger compartment for occupants; and a housing disposed through the instrument panel, wherein a heating and cooling module is disposed within the housing, which supplies regulated air to the passenger compartment, cools the battery for the electric vehicle, or cools the PE system.

[0005] The two patents mentioned above relate to the application of modular air conditioning systems in residential and automotive applications, respectively. Both shorten pipe lengths through system integration and centrally arrange the air conditioning system in a specific area. However, the existing design still has the following shortcomings: First, the presence of pipes increases the risk of refrigerant leakage, which is particularly critical for vehicle air conditioning systems using R290 refrigerant, requiring further reduction in the possibility of leakage; second, existing patents still have significant room for improvement in terms of installation efficiency, connection reliability, ease of later maintenance, and refrigerant transmission resistance and heat loss.

The two ends of the combination of the liquid receiver 1 and the evaporator 2 are held between the first extension 69 of the plate-shaped controller chamber 64 and the second extension 37 of the plate-shaped condenser 3 (the two opposite end faces of the liquid receiver 1 and the evaporator 2 are respectively attached to the side of the first extension 69 of the controller chamber 64 and the side of the second extension 37 of the condenser 3). Compared with the traditional barrel-shaped liquid receiver, the volume of the liquid receiver 1 is greatly increased, and the volume of the evaporator 2 is effectively expanded, thereby making full use of the limited space above the horizontal compressor housing, greatly enhancing the space utilization rate, and improving the COP (Coefficient of Performance) efficiency of the compressor.

During installation, the first step is to install the compressor 1 and the evaporator 2. The evaporator 2 is then lowered vertically, with the evaporator outlet pipe 22 aligned with the suction port 63. The evaporator inlet pipe 21 is connected to the vertical branch pipe of the second bypass channel 55 and installed until the end face fits. Then, the bottom connecting ear plate of the evaporator 2 is fastened to the first connecting seat 54 and the second connecting seat 65 of the evaporator with bolts.

[0108] The second step is to install the liquid receiver 1. Install the liquid receiver 1 along the compressor axis. Connect the liquid receiver outlet pipe 12 to the horizontal branch pipe of the second bypass channel 55. Connect the liquid receiver inlet pipe 13 to the first end of the straight pipe type first bypass channel 45. After installation until the end face fits, bolt the connecting lug plate at the bottom of the liquid receiver 1 to the first connecting seat 44 and the second connecting seat 53 of the liquid receiver 1. Bolt the connecting lug plate at one end of the liquid receiver 1 to the connecting lug plate at the end of the evaporator 2.

[0109] The third step is to install the condenser 3. The condenser 3 is installed along the compressor axis, with the first agent-side outlet 31 aligned with the second end of the straight-pipe first bypass channel 45, and the first agent-side inlet 32 ​​aligned with the exhaust port 41 of the front shell 4. Then, it is axially connected and fixed through the circumferential threaded through hole 35 of the condenser 3, the second threaded through hole 43 of the front shell, the bolt foot 52 of the middle shell 5, and the first threaded through hole 62 of the rear shell 6. The threaded hole 36 of the condenser 3 is connected and fixed to the connecting lug at the end of the liquid receiver 1 by bolts.

[0110] This invention provides an integrated air conditioning system structure. By eliminating traditional piping design, a flow channel structure is set on the housing, and the various components of the air conditioning system are directly integrated onto the housing through a sealing structure. Specifically, the housing has a flow channel structure for fluid flow (a first bypass channel 45 and a second bypass channel 55), which is integrally formed with the compressor housing. The flow channel structure connects the compressor to the condenser, liquid receiver, and evaporator through a sealing structure to achieve refrigerant flow. The sealing structure ensures the tightness of the connection between each component and the flow channel structure, preventing leakage. This structure significantly shortens the refrigerant flow path, significantly reduces the number of leakage points, and improves installation efficiency and space utilization. In addition, this design facilitates installation, operation, and subsequent maintenance management, and fundamentally improves the safety of the air conditioning system.

[0111] This utility model also provides a new energy vehicle, including the integrated compressor as described above, but not limited thereto. By using the integrated compressor of this utility model, the modular design enables the air conditioning system to be quickly and accurately connected to the vehicle's refrigeration system piping in the production line, significantly improving vehicle assembly efficiency.

[0112] In summary, the integrated compressor of this utility model and new energy vehicles can set a flow channel structure on the housing and directly integrate the various components of the air conditioning system onto the housing through a sealing structure, which greatly shortens the refrigerant flow path, significantly reduces the number of leakage points, and improves installation efficiency and space utilization.

[0113] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
