Description

Technical Field

[0001] The present invention relates to the field of vehicle refrigeration equipment, and more specifically, to an integrated compressor and a new energy vehicle. Background Art

[0002] With the emergence of new refrigerants, R290 has become an excellent option among the fourth-generation refrigerants HFOs, and it has an extremely broad application market. However, due to its flammability, R290 has extremely stringent requirements for the leak prevention ability and safety of the system.

[0003] CN208687899U discloses an air-cooled heat pump modular air conditioner unit, which relates to the technical field of air conditioning equipment and includes a plurality of air conditioner unit modules. The plurality of air conditioner unit modules are connected by fasteners. Each air conditioner unit module includes a bottom plate module, a control module, a compression module, a coil heat exchange module, and a fan module. The control module and the compression module are both installed on the bottom plate module; the coil heat exchange module is arranged above the compression module; the fan module is arranged above the coil heat exchange module; and it has the advantages of high modularity, convenient assembly, easy expansion, and strong versatility.

Compared with the traditional barrel-shaped liquid storage tank, the volume of the liquid reservoir 1 is greatly enhanced, and the volume of the evaporator 2 is effectively expanded, thereby making full use of the limited space above the horizontal compressor casing, greatly enhancing the space utilization rate, and improving the COP (abbreviation of Coefficient Of Performance) efficiency of the compressor.

Figure 12 Schematic diagram of the connection of the second bypass channel in the integrated compressor of the present invention. Figures 11 to 12As shown, in this embodiment, both the first bypass channel 45 and the second bypass channel 55 are integrally formed with the horizontal compressor housing.

Refer to Figure 10 As shown, the refrigerant completes its flow in the condenser 3 through the first agent-side inlet 32 and the first agent-side outlet 31, and the cooling water flows through the condenser through the first water-side inlet 33 and the first water-side outlet 34. The heat exchange between the water side and the agent side is carried out in the form of coiled pipes or fins inside the condenser. The screw connection through holes around the condenser 3 are used for connection with the compressor, and the condenser 3 is connected and fixed to the connecting ear plates of the liquid receiver 1 through the liquid receiver fixing holes.

[0107] Figure 11 is a connection schematic diagram of the first bypass channel in the integrated compressor of the present invention. Figure 12 is a connection schematic diagram of the second bypass channel in the integrated compressor of the present invention. As Figure 2 、 3 、11 and 12 show, the integrated air-conditioning system of this patent does not use external pipelines to connect each module. By arranging a flow channel structure on the compressor to connect each module and then using bolts for fixation, in the first step of installation, the compressor 1 and the evaporator 2 are installed. The evaporator 2 is vertically dropped. Among them, the evaporator outlet pipe 22 is aligned with the suction port 63, and the evaporator inlet pipe 21 is connected to the vertical branch pipe of the second bypass channel 55 and installed until the end faces fit. Then, the bottom connecting ear plates of the evaporator 2 are tightly connected to the first evaporator connecting seat 54 and the second evaporator connecting seat 65 through bolts.

[0108] In the second step, install the liquid reservoir 1. Install the liquid reservoir 1 along the axial direction of the compressor. Connect the outlet pipe 12 of the liquid reservoir to the horizontal branch pipe of the second bypass channel 55. Connect the inlet pipe 13 of the liquid reservoir to the first end of the straight-tube type first bypass channel 45. After installing until the end faces are in contact, then fixedly connect the connecting ear plates at the bottom of the liquid reservoir 1 to the first liquid reservoir connecting seat 44 and the second liquid reservoir connecting seat 53 by bolts, and fixedly connect the connecting ear plates at one end of the liquid reservoir 1 to the connecting ear plates at the end of the evaporator 2 by bolts.

[0109] In the third step, install the condenser 3. Install the condenser 3 along the axial direction of the compressor. Align the first agent side outlet 31 with the second end of the straight-tube type first bypass channel 45, and align the first agent side inlet 32 with the exhaust port 41 of the front shell 4. Then, axially connect and fix through the circumferential screw-through holes 35 of the condenser 3, the screw-through holes 43 of the front shell, the bolt pins 52 of the middle shell 5, and the screw-through holes 62 of the rear shell 6. Connect and fix the screw holes 36 of the condenser 3 to the connecting ear plates at the end of the liquid reservoir 1 by bolts.

[0110] The present invention provides an integrated air-conditioning system structure. By canceling the traditional pipeline design, a flow channel structure is provided on the housing, and each component of the air-conditioning system is directly integrated on the housing through a sealing structure. Specifically, the housing is provided with a flow channel structure (the first bypass channel 45 and the second bypass channel 55) for fluid circulation. The flow channel structure is integrally formed with the compressor housing. The flow channel structure connects the compressor with components such as the condenser, the liquid storage tank, and the evaporator through the sealing structure to realize the circulation of the refrigerant. The sealing structure is used to ensure the connection tightness between each component and the flow channel structure to avoid leakage. This structure greatly shortens the refrigerant circulation path, significantly reduces the number of leakage points, and at the same time improves the installation efficiency and space utilization rate. In addition, this design facilitates installation operation and later maintenance management, and fundamentally improves the safety of the air-conditioning system.

[0111] The present invention also provides a new energy vehicle, including the integrated compressor as described above, but not limited thereto. By using the integrated compressor of the present invention, the modular design enables the air-conditioning system to quickly and accurately dock with the refrigeration system pipeline of the vehicle on the production line, greatly improving the vehicle assembly efficiency.

[0112] In summary, the integrated compressor and the new energy vehicle of the present invention can set a flow channel structure on the housing, and directly integrate each component of the air-conditioning system on the housing through a sealing structure, greatly shortening the refrigerant circulation path, significantly reducing the number of leakage points, and at the same time improving the installation efficiency and space utilization rate.

[0113] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, and all should be regarded as falling within the protection scope of the present invention.
