Each functional module can be equipped with a different functional cavity shell according to the different configurations of the functional parts to be installed. Different functional modules are detachably connected and installed through assembly parts to form a variety of air-conditioning structures with functional parts with different configurations.

[0042] Modular assembly of the air conditioner structure can simplify the structure of the air conditioner, eliminate the compatibility structure design in the original air conditioner, reduce the waste of raw materials, reduce production costs, and reduce the weight of the air conditioner.

[0043] If the air conditioner structure is divided into m modules, each module has n different configurations, and multiple modules can be arranged and combined into air conditioners with N configurations, where N = n1*n2...*n m / (m*(m-1) … 1) The modules of the air conditioner structure can be selected or adjusted according to the needs, and the air conditioner can be divided into multiple modules. The size of each module is smaller than the overall structure of the air conditioner, which is conducive to forming a more flexible production line and improving the utilization rate of the production space.

[0044] Furthermore, the functional module includes an indoor module, a compressor module, and a condensing module, and the indoor module, the compressor module, and the condensing module are connected and fixed by assembling parts to form a whole.

[0045] Among the above-mentioned functional modules, the indoor module can be distinguished and set into n1 types due to the different configurations in the electric control box, the compressor cavity module can be distinguished and set into n2 types according to the configuration factors such as the compressor structure, cooling only or heating and cooling, whether battery refrigeration is integrated, etc., and the condensing cavity module can be distinguished and set into n3 types according to the different types of condensers 32 (copper tube aluminum fin condenser, microchannel condenser, whether water circuit PTC is integrated). N types of air-conditioning structures can be determined through the indoor module, the compressor module and the condensing module, then N=n1*n2*n3*1 / 6.

[0046] It should be explained in detail that the indoor module includes an indoor cavity bottom shell 1 and an evaporator connected to the indoor cavity bottom shell 1, the compressor module includes a compressor cavity bottom shell 2 and a compressor installed in the compressor cavity bottom shell 2, and the condensing module includes a condensing cavity bottom shell 3 and a condensing fan installed in the condensing cavity bottom shell 3.

[0047] The indoor module provides cold air to the interior of the vehicle in the air conditioning cooling mode and provides hot air to the interior of the vehicle in the air conditioning heating mode. Figure 1-3 As shown, the indoor cavity bottom shell 1 serves as the bearing structure of the indoor module, and an air supply port and an air return port are arranged on the indoor cavity bottom shell 1, and the air supply port and the air return port are both connected to the vehicle interior, which is convenient for the input and / or output of airflow. For example, when the air conditioner is cooling, the air supply port can deliver the cold air processed by the evaporator to the vehicle interior, and the air return port can output the hot air in the vehicle interior.

[0048] Furthermore, the air supply outlet and the air return outlet may be in one or more of a rectangular, square, circular, elliptical, and diamond shape, and those skilled in the art may select and design them according to actual needs. Preferably, the air supply outlet and the air return outlet in the present application are in a rectangular shape.

[0049] Furthermore, filter screens are provided at the air supply and return ports, and filters for filtering dust and impurities are provided on the filter screens. Furthermore, filter holes are provided on the filter screen for air flow, and the shape and number of the filter holes can be selected and designed by a person skilled in the art according to actual conditions, and the filter holes can be provided in any one or more of circular, elliptical, rectangular, square, arc-shaped, and leaf-shaped shapes.

[0050] Furthermore, those skilled in the art can set the number of air supply ports and air return ports according to the size of the vehicle body. Preferably, in the present application, there are two air supply ports and one air return port, wherein the air supply ports include a first air supply port 11 and a second air supply port 13, and the air return port includes a first air return port 12.

[0051] The interior cavity bottom shell 1 is provided with a longitudinal beam contact surface 14 and a cross beam contact surface 15 for connecting and fixing the frame assembly 4. The interior cavity bottom shell 1 is connected to the profile longitudinal beam by installing a connecting piece at the longitudinal beam contact surface 14, and the interior cavity bottom shell 1 is connected to the profile cross beam by installing a connecting piece at the cross beam contact surface 15.

[0052] The compressor module includes a compressor chamber bottom shell 2 and a compressor installed in the compressor chamber bottom shell 2. Figure 4-6 As shown, a cavity for installing the compressor is provided on the bottom shell 2 of the compressor cavity, the depth of the cavity is the longitudinal height of the compressor, and the bottom shell 2 of the compressor cavity is provided with a side wall 21 for installation, and the side wall 21 is provided with a fixing hole 22. The frame assembly 4 is clamped at the lower part of the side wall 21, thereby connecting the compressor module with other modules as a whole.

[0053] like Figure 7-9 As shown, the condensing chamber bottom shell 3 is provided with a condensing fan chamber 31 and a condenser core chamber 32. A plurality of condensing fan chambers 31 and condenser core chambers 32 are provided according to the size of the vehicle body. Accordingly, one condensing fan chamber 31 is provided with one condensing fan, and one condenser is provided with one condenser core chamber 32. Preferably, three condensing fans are provided in the present application, and one condenser is provided.

[0054] The shape of the condensing fan cavity is adapted to the shape of the condensing fan. Preferably, the condensing fan cavity in this embodiment is circular. The condenser condenses and dissipates heat, and the high-temperature and high-pressure refrigerant condenses and transfers heat to the air medium. The condensing fan discharges the high-temperature gas into the external environment, thereby achieving the purpose of heat dissipation.

[0055] As an embodiment of the present application, Figure 10-11 As shown, the various functional modules are connected into a whole through an assembly part, and the assembly part is a frame assembly 4 , and the frame assembly 4 includes a cross beam 41 and a longitudinal beam 42 .

[0056] Furthermore, the cross beam 41 and the longitudinal beam 42 are detachably connected. The cross beam 41 and the longitudinal beam 42 are connected by snapping or fixedly connected by a connecting piece, and preferably, the connecting piece is a fixing screw.

[0057] like Fig.10 As shown, the cross beam 41 includes a first cross beam, a second cross beam, and a third cross beam, and the longitudinal beam 42 includes a first longitudinal beam, a second longitudinal beam, and a third longitudinal beam. Specifically, the first longitudinal beam, the second longitudinal beam, and the first cross beam form a rectangular structure with an open end, wherein the second cross beam and the third cross beam are located in the rectangular structure, the second cross beam and the third cross beam are parallel to the first cross beam, and the second cross beam and the third cross beam are perpendicular to each longitudinal beam 42.

[0058] Furthermore, the first longitudinal beam and the second longitudinal beam are respectively arranged at the two ends of the first cross beam, the second cross beam and the third cross beam, and the second cross beam is between the first cross beam and the third cross beam.

[0059] Further, the first longitudinal beam and the second longitudinal beam are respectively located at two ends of the cross beam 41, and the first longitudinal beam is parallel to the second longitudinal beam. The ends of the third longitudinal beam are respectively connected to the first cross beam and the second cross beam, and are perpendicular to the first cross beam and the second cross beam.

[0060] like Fig.10 , 13 As shown, a condenser is installed in the area formed by the first cross beam, the second cross beam and the first longitudinal beam, so as to form a condensing module; a compressor is installed in the area formed by the second cross beam, the third cross beam and the first longitudinal beam, so as to form a compressor module; an indoor cavity bottom shell is provided in the area formed by the third cross beam and the first longitudinal beam, so as to form an indoor module.

[0061] like Figure 10-12 As shown, the frame assembly 4 is made of profiles, and the cross beam 41 is a profile cross beam, and the longitudinal beam 42 is a profile longitudinal beam.

[0062] Furthermore, the profile is a four-groove profile, on which a plurality of cross-sectional grooves for installing functional parts are arranged. The four-groove profile not only has a plurality of cross-sectional grooves, but also can withstand greater pressure without being easily deformed.

[0063] Furthermore, the four-slot profile is usually made of aluminum alloy material, and the wall thickness of the four-slot aluminum alloy profile is usually set in various sizes such as 1.8mm, 2mm, 2.5mm, 3mm, 3.2mm, etc. Technical personnel in this field can select the wall thickness type of the four-slot profile according to the weight of the functional parts to be installed. Generally, the thicker the wall of the four-slot aluminum alloy profile, the greater the bearing capacity, and the thinner the wall of the four-slot aluminum alloy profile, the smaller the bearing capacity.

[0064] Using the above four-groove profile as the frame assembly 4 can not only reduce the weight and improve the stability of the material, but also make the structure free from the influence of electrochemical corrosion.

[0065] The top cover is covered on the upper part of the functional module, and the top cover is fixed on the frame assembly 4 through a connecting piece.

[0066] The operating principle of the functional module composed of the indoor module, the compressor module and the condensing module is as follows: the compressor inhales the low-temperature and low-pressure gaseous refrigerant coming out of the evaporator. After being processed by the compressor, the temperature and pressure of the refrigerant rise and become a refrigerant in a high-temperature and high-pressure state; the refrigerant in a high-temperature and high-pressure state enters the condenser 32, and in the condenser 32, through heat exchange with the outside air, the heat is released and liquefied into a liquid to complete the condensation process, and the refrigerant will become a high-pressure and medium-temperature liquid refrigerant. The high-pressure and medium-temperature liquid refrigerant passes through the expansion valve and becomes a mist-like low-temperature and low-pressure refrigerant. The mist-like refrigerant will quickly absorb the surrounding heat, thereby evaporating the refrigerant into a gas, and the hot air in the car interior exchanges heat with the refrigerant through the evaporator, the air is cooled, and the cold air is transported to the car through the air supply port, and the refrigerant after heat exchange output from the evaporator is sucked into the compressor again to start a new cycle.

[0067] Compared with the prior art, the above technical solution in this embodiment has the following beneficial technical effects:

[0068] By designing the air conditioner into different configuration modules, the air conditioner is combined in the form of configuration, and each module is assembled into different units through a connection structure, thereby meeting the air conditioner configuration under different requirements;

[0069] The compatibility structure in the original equipment is cancelled, the structural setting is simplified, the waste of raw materials is reduced, and the weight of the device is reduced;

[0070] The air-conditioning structure is divided into multiple different modules, each of which is smaller than the size of the air-conditioning unit. During production, a more flexible production line can be formed, which improves the utilization rate of production space and reduces production costs.

[0071] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced.
