Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning compressors, in particular to a tapered tube. Background Art

[0002] The tapered tube on the air conditioning compressor housing is primarily used for air intake. This design allows air or refrigerant to enter the compressor through the tapered tube, helping the compressor work more efficiently. The shape of the tapered tube helps guide the flow of gas, improving compression efficiency, while also aiding in heat dissipation, ensuring the compressor maintains an appropriate temperature while operating efficiently. This design is particularly common in air conditioning compressors, where the intake duct is usually covered with a filter to ensure that the air or refrigerant entering the compressor is clean and prevent impurities from entering the compressor and causing damage.

[0003] Existing conical tubes are usually made of copper tubes because they have excellent pressure resistance, corrosion resistance, thermal conductivity, and mechanical properties. However, copper tubes are relatively expensive. Some use steel tubes, which reduces costs to a certain extent. However, due to the characteristics of steel, especially in the narrow-mouthed guide section, the gas conduction and heat conduction efficiency of steel tubes is insufficient, and the guide section is more easily damaged. Therefore, the present invention proposes a conical tube to solve the problems existing in the existing technology. Summary of the Invention

[0004] In response to the above problems, the present invention proposes a tapered tube, which is formed by integrally forming a thick-mouthed steel tube, a guide steel tube and a narrow-mouthed steel tube, and covering the narrow-mouthed steel tube with a layer of outer copper tube. While reducing costs, it maintains the flow conduction, heat conduction and mechanical properties of the narrow-mouthed section, ensuring the normal function of the air-conditioning compressor.

[0005] To achieve the purpose of the utility model, the utility model is implemented through the following technical solutions: a tapered tube, comprising a thick-mouthed steel tube, a guide steel tube and a narrow-mouthed steel tube, wherein the guide steel tube is arranged at the lower end of the thick-mouthed steel tube, the narrow-mouthed steel tube is arranged at the lower end of the guide steel tube, and the outer side of the narrow-mouthed steel tube is covered with an outer copper tube;

[0006] The guide steel pipe is provided with inner steps inside, and the inner steps are provided in multiple groups. The inner steps at the upper end and the inner steps at the lower end are connected to the thick-mouthed steel pipe and the narrow-mouthed steel pipe respectively.

[0007] A further improvement is that guide angles are provided at the inner corners of the multiple groups of inner steps, and the multiple groups of inner steps are formed in one piece.

[0008] A further improvement is that the thickness of the outer copper tube is 15-25 μm, and the outer copper tube and the narrow-mouth steel tube are fixed by electroplating or cladding.

[0009] A further improvement is that the thick-mouthed steel pipe, the guide steel pipe and the narrow-mouthed steel pipe are seamlessly integrated, and the centers of the thick-mouthed steel pipe, the guide steel pipe and the narrow-mouthed steel pipe are located on the same vertical line.

[0010] A further improvement is that the thick-mouthed steel pipe, the guide steel pipe and the narrow-mouthed steel pipe have the same thickness, and the outer copper pipe has a thickness greater than that of the narrow-mouthed steel pipe.

[0011] A further improvement is that connecting ribs are provided on the outside of the thick steel pipe and the guide steel pipe, and the connecting ribs are embedded in the side walls of the thick steel pipe and the guide steel pipe, and the outer copper pipe is connected to the bottom of the connecting ribs.

[0012] A further improvement is that: there are at least three groups of connecting ribs, and the three groups of connecting ribs are arranged at equal angles around the center of the thick-mouthed steel pipe, and the lower ends of the connecting ribs are embedded and fixed into the side wall of the outer copper pipe.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model adopts a thick-mouthed steel pipe, a guide steel pipe and a narrow-mouthed steel pipe as an integral part, and covers the narrow-mouthed steel pipe with a layer of outer copper pipe. While reducing the cost, it maintains the flow and heat conduction and mechanical properties of the narrow-mouthed section, ensuring the normal function of the air-conditioning compressor.

[0015] 2. The utility model sets multiple sets of connecting inner steps on the inner side of the guide steel pipe to enhance the strength of the guide steel pipe.

[0016] 3. The utility model connects multiple groups of connecting ribs on the outside of the thick steel pipe and the guide steel pipe, and uses the connecting ribs to connect the outer copper pipe below, thereby enhancing the connection strength between the outer copper pipe and the overall pipe, preventing it from falling off, and improving the overall stability.

While reducing costs, the flow and heat conduction and mechanical properties of the narrow-mouthed section are maintained, ensuring the normal function of the air-conditioning compressor.

[0023] The guide steel tube 2 is provided with an inner step 5, and the inner step 5 is provided in multiple groups. The inner step 5 at the upper end and the inner step 5 at the lower end are connected to the thick-mouthed steel tube 1 and the narrow-mouthed steel tube 3, respectively. When in use, the multiple groups of connecting inner steps 5 provided on the inner side of the guide steel tube 2 enhance the strength of the guide steel tube 2, allowing it to withstand greater wind pressure during the process of guiding the airflow, and preventing the guide steel tube 2 from cracking and damage.

[0024] The inner corners of the multiple sets of inner steps 5 are all provided with guide angles 6, and the multiple sets of inner steps 5 are integrally formed. By utilizing the function of the guide angles 6, the sharp angles of the inner steps 5 are changed to obtuse angles, thereby reducing the wear of the inner steps 5 by wind pressure.

[0025] The outer copper tube 4 is 20 μm thick and is secured to the narrow-mouth steel tube 3 via electroplating or cladding. The thick steel tube 1, guide steel tube 2, and narrow-mouth steel tube 3 are integrally formed, and the narrow-mouth steel tube 3 is covered with an outer copper tube 4. This reduces costs while maintaining the fluid conduction, heat conductivity, and mechanical properties of the narrow-mouth section, ensuring proper function of the air conditioning compressor.
