Description

Technical Field

[0001] The invention belongs to the field of automobile air-conditioning heat pump system, and in particular relates to a liquid storage dryer cylinder. Background Art

[0002] The liquid storage dryer is a special component that has been continuously improved and updated in the development of air conditioning. Its main function is the "liquid storage" and "drying" mentioned in the name, that is, the "liquid storage dryer" involved in the refrigeration principle. The liquid storage dryer came into being with the development of modern refrigeration technology. In the refrigeration principle, the refrigerant achieves the effect of heat absorption and heat release through the transformation of physical form. When the refrigerant is added to the air-conditioning sealed system, it will inevitably be mixed with moisture in the air and impurities in the pipeline. During the physical transformation process, the moisture will freeze into solid ice, blocking the airtight pipeline of the air-conditioning system, thereby affecting the flow of refrigerant, and eventually leading to refrigeration failure, and in severe cases, explosion. The function of the liquid storage dryer is to absorb the moisture in the sealed air-conditioning pipeline and filter out the tiny impurities in the pipeline. Liquid storage dryers are widely used in household air conditioners, car air conditioners, central air conditioners and other fields. Liquid storage dryers usually remove moisture from liquids by heating, reducing pressure or using dry gas flow. Its basic principle is to evaporate the liquid through heat energy or other means to obtain dry solid materials or concentrated liquids. The original liquid storage dryer cylinder was stamped. With the gradual advancement of new energy electric vehicles, the weight of components is required to be reduced. The cylinder adopts a stamped structure. After the cylinder wall is thick, the weight of the cylinder itself is heavy and the circumferential wall thickness is uneven, which may affect the sealing performance.

[0022] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0023] like Figure 1 As shown, a liquid storage dryer cylinder includes a cylinder 1 and a sleeve 2, wherein the cylinder 1 is arranged in the sleeve 2, and the cylinder 1 has a uniform wall thickness. The cylinder 1 is obtained by an extrusion process to obtain an extruded profile, and the use of the extruded profile can achieve a more uniform wall thickness, achieve liquid storage and pressure resistance performance, and reduce the weight of the product itself.

[0024] like Figure 1 and Figure 2 As shown, one end of the cylinder 1 is provided with a water inlet 3, and one end of the water inlet 3 is a flared structure 7. One end of the water inlet 3 is the flared structure 7, which can increase the volume inside the cylinder 1 and allow more fluid to enter the receiver-drier.

[0025] The other end of the cylinder 1 is provided with a rear cover 8, which is a sealing structure. The rear cover 8 is welded by argon arc welding after extrusion, and is polished to form a sealing structure after welding. The rear cover 8 is a argon arc welded rear cover plate, and the weld quality of argon arc welding is high, ensuring the stability of the rear cover 8 and better sealing.

[0026] The outer wall of the cylinder 1 near the expansion mechanism 7 is provided with a water outlet 4, and the water outlet 4 is connected with a pipe 10, and the pipe 10 is connected with the condenser pipe. The water outlet 4 is provided with a pipe 10, and the pipe 10 is connected with the pipe of the condenser to realize the cooling and temperature reduction of the fluid.

[0027] A fixing port 6 is provided on the outer wall of the cylinder 1 near one end of the rear cover 4, and the fixing port 6 is connected to the condenser. The fixing port 6 is used to fix the liquid receiver-drier and can be fixed to the condenser to ensure stable operation.

[0028] An interface 5 is provided between the water outlet 4 and the fixing port 6, and a positioning pin 9 is provided on the interface 5. The interface 5 is provided with a positioning pin 9, and the cylinder 1 and the sleeve 2 form a latch positioning structure. The latch structure can improve safety and has strong impact and vibration resistance. The positioning pin 9 can limit the relative displacement of the cylinder 1 and the sleeve 2.

[0029] The positions of the water outlet 4 and the interface 5 match the position of the condenser flow channel. The center distance between the water outlet 4 and the interface 5 is processed by a milling machine, which can achieve high-precision processing because there are fewer milling chips and no excessive thermal deformation of the workpiece, thereby ensuring processing accuracy. During processing, the relative position of the water outlet 4 and the interface 5 is adjusted according to the position of the condenser flow channel, which facilitates the change of the condenser flow channel and simplifies the layout of the condenser flow channel.

[0030] The flared structure 7 is conical; the rear cover 8 is a plane; the water outlet 4, the interface 5, the fixing port 6 and the sleeve 2 are an integrated structure. The flared structure 7 is conical, and the generatrix angle of the flared structure 7 is 40°; the rear cover 8 is a plane, which is more stable when placed, and the wall thickness of the rear cover 4 is greater than 2 mm to avoid easy damage. The water outlet 4, the interface 5, the fixing port 6 and the sleeve 2 are an integrated structure, which is more stable and not easily damaged during the working process.

[0031] The ends of the cylinder 1 and the sleeve 2 are chamfered; the flared structure 3 is provided with chamfers; the water outlet 7, the interface 8 and the fixing port 9 are cylindrical. The chamfers of the ends of the cylinder 1 and the sleeve 2 can remove the burrs left after processing, improve safety, reduce stress concentration, and improve fatigue strength and stress resistance. The chamfer of the flared structure 3 can not only remove the burrs left after processing to prevent stress concentration, but also reduce the resistance in the fluid flow process, and prevent the fluid from flowing too fast when entering the liquid storage dryer. The cylindrical water outlet 7, the interface 8 and the fixing port 9 are more suitable for connection with the condenser. The material of the cylinder 1 is 3003-H112, and the material of the sleeve 2 is aluminum alloy 4343 / 3003-H14; the material of the cylinder 1 is 3003-H112, which has excellent anti-rust performance, good formability and weldability, and good corrosion resistance; the material of the sleeve 2 is aluminum alloy 4343 / 3003-H14, which has excellent thermal conductivity, high strength and rigidity, and good processing performance.

[0032] Working principle of the present invention: A liquid storage dryer cylinder, including a cylinder 1 and a sleeve 2. The cylinder 1 adopts an extrusion process, and the cylinder 1 is an extruded tube with uniform wall thickness. A water inlet 3 is provided at one end of the cylinder 1, and a flaring structure 7 is provided at one end of the water inlet 3. The flaring structure 7 can increase the internal area of ​​the cylinder 1. A water outlet 4, an interface 5 and a fixing port 6 are provided on the outer wall of the cylinder 1.
