Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle-mounted air conditioners, and particularly relates to a detachable and lightweight air duct for an air conditioner. Background Art

[0002] An air duct for an air conditioner is usually provided on the top of a special vehicle. The existing air ducts are generally of a fixed structure. After installation, it is difficult to adjust or reconfigure according to actual needs, with poor adaptability. And it is difficult to clean and maintain the inside of the air duct. If there is a leak or damage in the air duct, the repair is relatively troublesome; in some environments with limited space, the air duct layout will also be affected, resulting in uneven air volume distribution. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a detachable and lightweight air duct for an air conditioner, which is convenient for regular maintenance, cleaning or replacement of components of the air duct.

[0004] To solve the above technical problem, the technical solution of the present invention is: a detachable and lightweight air duct for an air conditioner, including two U-shaped air ducts and two straight air ducts. Both ends of the two straight air ducts are movably connected to the U-shaped air ducts through connectors, so that the entire air duct forms a square ring.

[0005] The detachable air duct provided by the above technical solution is assembled by two U-shaped air ducts and two straight air ducts through connectors. In this way, it can be laid out and adjusted according to actual needs to adapt to changes in different spaces and usage scenarios; and it is easy to disassemble and reassemble, which is convenient for regular maintenance, cleaning or replacement of components; thus, it can improve the energy efficiency of the overall system and reduce energy consumption.

[0006] In one embodiment, the connector includes a first connector and a second connector that cooperate with each other. One end of the first connector is inserted into the port of the U-shaped air duct and fixed by a rivet. One end of the second connector is inserted into the port of the straight air duct and fixed by a rivet. The first connector and the second connector are spliced through a mortise and tenon structure and fixed by screws.

[0007] In one embodiment, one end of the first connector is provided with a rectangular tenon, and one end of the second connector is provided with a rectangular mortise adapted to the rectangular tenon. Both the tenon and the mortise are set to be rectangular, so that it is very convenient to assemble and disassemble the first connector and the second connector in a pulling manner.

[0008] In one embodiment, sealing rubber strips are provided on the upper and lower end faces of the rectangular tenon.

[0009] In one embodiment, sealing rubber strips are provided on the inner side walls of the rectangular mortise.

[0010] In one embodiment, a limiting plate is provided on one side of the rectangular tenon.

[0011] In one embodiment, the first connector and the second connector are both made of aluminum alloy, and a rubber-plastic plate is attached to the inner wall of the aluminum alloy to prevent cold air from condensing into water droplets.

[0012] In one embodiment, both the U-shaped air duct and the I-shaped air duct are formed by processing with carbon fiber plates. The carbon fiber plates have high strength and rigidity, and are very light, meeting the lightweight requirements, and have good corrosion resistance. At the same time, they have a low thermal expansion coefficient, and can maintain dimensional stability in the air conditioning system, and can be applied to various scenarios.

[0018] As Figure 1 shown, a detachable and lightweight air duct for an air conditioner includes two U-shaped air ducts 1 and two straight air ducts 2. Both ends of the two straight air ducts 2 are movably connected to the U-shaped air ducts 1 through connectors, so that the entire air duct forms a square ring; the connector includes a first connector 3 and a second connector 4 that cooperate with each other. One end of the first connector 3 is inserted into the port of the U-shaped air duct 1 and fixed by a rivet, and one end of the second connector 4 is inserted into the port of the straight air duct 2 and fixed by a rivet. The first connector 3 and the second connector 4 are spliced through a mortise and tenon structure and fixed by screws.

[0019] Since the detachable air duct for an air conditioner provided in this embodiment is assembled by two U-shaped air ducts 1 and two straight air ducts 2 through connectors, it can be laid out and adjusted according to actual needs to adapt to changes in different spaces and usage scenarios; moreover, it is easy to disassemble and reassemble, facilitating regular maintenance, cleaning or replacement of components; thus, it can improve the energy efficiency of the overall system and reduce energy consumption.

[0020] As Figures 2 to 7As shown, in this embodiment, one end of the first connector 3 is designed as a rectangular tenon, and one end of the second connector 4 is designed as a rectangular mortise that is compatible with the rectangular tenon. Since the tenon and the mortise are both set to be rectangular, the first connector 3 and the second connector 4 can be assembled and disassembled very conveniently by pulling. In order to enhance the sealing between the first connector 3 and the second connector 4, a sealing strip 5 is provided on the upper and lower end surfaces of the rectangular tenon, and a sealing strip 5 is also provided on the inner side wall of the rectangular mortise. In order to ensure that the screw holes of the first connector 3 and the second connector 4 can be quickly aligned, a stop plate is provided on one side of the rectangular tenon.

The carbon fiber plates have high strength and rigidity, and are very light in weight, meeting the lightweight requirements. They also have good corrosion resistance. At the same time, they have a low thermal expansion coefficient, can maintain dimensional stability in the air conditioning system, and can be used in various scenarios.

[0022] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of the patent of the present invention.
