Furthermore, the condenser core has a large base for sealing. This structure leads to high overall cost, weight, and manufacturing difficulties. To further optimize products and enhance market competitiveness, and given the rising living standards and increasing demands for air conditioning performance, optimizing and improving existing products to enhance cooling performance is crucial for accelerating business development and strengthening the overall capabilities of air conditioning companies.

[0003] On the one hand, the rigid pipe connection between the condenser and evaporator presents installation difficulties. On the other hand, the piping of both units, along with the liquid receiver and dryer, are all located at the evaporator's return air inlet, affecting the gas return airflow. Furthermore, the presence of a sealing plate under the condenser core results in high overall cost, heavy weight, and manufacturing difficulties. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this 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.

[0027] like Figure 1 As shown, a novel split air conditioning system includes a condenser assembly 1 and an evaporator assembly 2. The condenser assembly 1 is located at the front, and the evaporator assembly 2 is located at the rear. The condenser assembly 1 and the evaporator assembly 2 are connected by a combination of flexible hoses and rigid pipes.

[0028] Better yet, rigid pipes are connected to the left and right sides of the evaporator assembly 2, and flexible pipes are used to connect the left and right sides of the condenser assembly 1 to the rigid pipes of the evaporator assembly 2, thereby improving the flexibility and efficiency of the connection between the two components.

[0029] like Figure 2As shown, the condenser assembly 1 includes condenser cover assemblies 11 located on the left and right sides. Hinges 12 are provided on opposite sides of the two condenser cover assemblies 11. The condenser cover assemblies 11 are connected to the hinge fixing brackets 13 through the hinges 12. In this way, the condenser cover assemblies 11 on both sides are combined by using the hinge fixing brackets 13, so that one side of each condenser cover assembly 11 is connected to the housing assembly 20, and the other side is connected to the hinge fixing brackets 13 through the hinges. The hinge structure can realize the flipping function of the condenser cover assembly 11.

[0030] Furthermore, bolt fixing holes are provided on the hinge fixing bracket 13, which is connected to the fan cover assembly 15 by bolts, providing support and fixation for the fan cover assembly 15. Additionally, a lifting ring 14 is provided on the fan cover assembly 15, and a condenser fan 16 is located below the fan cover assembly 15. Thus, the lifting ring 14, fan cover assembly 15, and hinge fixing bracket 13 are connected in series, achieving three functions in one series, simplifying the structure and facilitating the hoisting of the entire unit. Even better, for the fan cover assembly 15, a first bending structure 17 is provided at the front end of the fan cover assembly 15, which can better enclose and fix the internal components.

[0031] like Figure 3 As shown, the housing assembly 20 is located at the bottom of the condenser assembly 1 and is mainly used to install components such as the condenser core, fan cover, and piping. The housing assembly 20 is provided with a cover fixing bracket 21, a front connecting plate 22, and a rear connecting plate 23. The cover fixing bracket 21 is welded to the left and right sides of the housing assembly 20 to facilitate the fixing of the condenser cover assembly 11. The rear connecting plate 23 has a wire-passing hole for easy wiring. The front connecting plate 22 has a second bending structure, within which a liquid receiver 24 and a dryer 25 are fixedly installed. The second bending structure facilitates the fixing of the liquid receiver and dryer with metal clamps. Furthermore, the second bending structure connects to the first bending structure 17 at the front end of the fan cover assembly 15, increasing the overall strength and stability of the unit, while also simplifying the overall structure and improving its appearance.

[0032] The outlet of the dryer 25 is connected to the outlet rigid pipe assembly 26, and the other end of the outlet rigid pipe assembly 26 is connected to the outlet connecting hose 27. The same design is used for the air inlet pipe: the air inlet of the liquid reservoir 24 is connected to the air inlet rigid pipe assembly 28, and the other end of the air inlet rigid pipe assembly 28 is connected to the air inlet connecting hose 29. This design can reduce the processing difficulty of long rigid pipes, and at the same time improve the connection flexibility between the pipes of the condenser assembly 1 and the evaporator assembly 2, making it easier for the pipes to be connected.

[0033] Better yet, the intake hard pipe assembly 28 is fixed to the housing assembly 20 by the pipe fixing bracket 30; the liquid outlet hard pipe assembly 26 is fixed to the housing assembly 20 by the pipe fixing clamp 31.

[0034] In addition, a left condenser core 32 and a right condenser core 33 are fixedly mounted on the housing assembly 20, and a core connecting plate 34 is provided between the left condenser core 32 and the right condenser core 33. At the same time, the front and rear ends of the left condenser core 32 and the right condenser core 33 are connected to the front connecting plate 22 and the rear connecting plate 23, respectively, so that the left condenser core 32 and the right condenser core 33 are connected in series by the front connecting plate 22 and the rear connecting plate 23, and are fixed to the housing assembly 20 as a whole by bolts.

[0035] Furthermore, both the left condenser core 32 and the right condenser core 33 are provided with front and rear side plates, and threaded holes are opened on the front and rear side plates of the core. The hinge fixing bracket 13 is fixed to the front and rear side plates of the left and right condenser cores by bolt connection.

[0036] like Figure 4 As shown, the housing assembly 20 includes a front crossbeam 201, a middle crossbeam 202, and a rear crossbeam 203 arranged in parallel. The left and right ends of the front crossbeam 201, the middle crossbeam 202, and the rear crossbeam 203 are respectively connected to the left longitudinal beam 204, the right longitudinal beam 206, the left sealing base plate 205, and the right sealing base plate 207.

[0037] It should be noted that the left longitudinal beam 204, right longitudinal beam 206, left sealing base plate 205, and right sealing base plate 207 are all arranged in parallel, with the left sealing base plate 205 and right sealing base plate 207 located on the inner side, and the left longitudinal beam 204 and right longitudinal beam 206 located on the outer side. Thus, to simplify the structure, this utility model designs the front, middle, and rear crossbeams to have the same structure, and the left and right longitudinal beams and sealing plates to have symmetrical and identical structures. Welding is used between the sheet metal parts to improve the overall strength of the machine.

[0038] To facilitate a sealed connection between the condenser and the bus roof, a sealing sponge strip 208 is installed at the bottom of both the left and right sealing base plates 205 and 207, and a base plate sealing sponge strip 210 is installed at the top of both plates. A crossbeam under-beam sponge strip 209 is installed at the bottom of the front crossbeam 201, middle crossbeam 202, and rear crossbeam 203. This utilizes the compressibility of the sponge strips to achieve a tight seal on the roof. This also solves the air leakage problem caused by the lack of a base plate at the bottom of the condenser core. The base plate sealing sponge strip 210 is attached above the left and right sealing base plates, allowing it to contact the condenser core and further improving the overall sealing performance and heat exchange efficiency.

[0039] The beneficial effects of this utility model are as follows:

[0040] First: The condenser and evaporator are designed as separate structures, and the pipes between the two are connected by a combination of rigid pipes and flexible pipes, which improves the flexibility of the connection and assembly of the two units and reduces the difficulty of pipe processing and assembly.

[0041] Second: The liquid receiver, dryer and piping inside the two units are all arranged at the front end of the condenser, which solves the problems of poor return air effect and poor cooling performance of conventional air conditioners.

[0042] Third: The integrated sealing base plate on the housing assembly is replaced with a small sealing plate for local sealing, which reduces costs and weight without affecting the overall sealing performance.

[0043] Fourth: Sponge strips are installed under each housing component, which can be sealed to the roof of the vehicle, simplifying the overall structure and weight while solving the air leakage problem.

[0044] Fifth: The core front connecting plate is designed with a bending structure, which can be used with metal clamps to fix the liquid reservoir, dryer, pipelines, etc. to the core front connecting plate, simplifying the structure and facilitating the installation of the whole machine.

[0045] Sixth: The front end of the condenser fan cover assembly is designed with a bent structure, which can fit tightly with the bent front connecting plate of the core. On the one hand, it covers the liquid receiver, dryer, pipelines, etc., improving the appearance of the structure. On the other hand, it can be connected in series with the condenser core and shell, which can strengthen the fixation and improve the overall strength and stability of the machine.

[0046] Seventh: The condenser cover assembly is designed as a hinge flip-type assembly with a dedicated hinge fixing bracket. This facilitates the installation and flipping of the hinge and cover, and allows the condenser core and fan cover assembly to be connected in series. Bolts are used to achieve a three-in-one connection, simplifying the assembly process and improving the overall assembly efficiency.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
