Description

Technical Field

[0001] This invention belongs to the field of automotive air conditioning heat pump systems. Specifically, this invention relates to a liquid storage dryer cylinder. Background Technology

[0002] Liquid receiver-dryers are a crucial component in the continuous improvement and upgrading of air conditioning systems. Their primary functions, as the name suggests, are "liquid storage" and "drying," reflecting the principles of refrigeration. Liquid receiver-dryers emerged with the development of modern refrigeration technology. In refrigeration, refrigerant undergoes physical transformations to absorb and release heat. When refrigerant is added to the sealed system of an air conditioner, moisture from the air and impurities from the pipes inevitably enter. During these transformations, moisture can solidify into ice, clogging the sealed pipes of the air conditioning system, affecting refrigerant flow, ultimately leading to refrigeration failure, and in severe cases, explosion. The function of a liquid receiver-dryer is to absorb moisture from the sealed air conditioning pipes while filtering out minute impurities. Liquid receiver-dryers are widely used in household air conditioners, automotive air conditioners, and central air conditioning systems. They typically remove moisture from liquids through heating, pressure reduction, or the use of dry gas flow. The basic principle is to evaporate the liquid using heat or other methods, resulting in a dry solid or concentrated liquid. The original liquid storage dryer cylinder was made of stamping. With the gradual advancement of new energy electric vehicles, there is a requirement to reduce the weight of components. The cylinder is now made of stamping structure. However, with the increased wall thickness, the cylinder itself is too heavy and the wall thickness is uneven around the perimeter, which may affect the sealing performance.

[0003] Chinese patent CN203771827U disclosed a car air conditioning condenser liquid receiver dryer on August 13, 2014, including a dryer cylinder with a dryer inside. The dryer cylinder includes a cylinder body and a top cover connected to one end of the cylinder body. A connecting sleeve connected to the car air conditioning manifold is provided on the cylinder body. This car air conditioning condenser liquid receiver dryer adopts a split structure, which has low stability. The cylinder body wall is relatively thick, the cylinder body itself is heavy, and the circumferential wall thickness is uneven, which may affect the sealing performance. Summary of the Invention

[0004] The present invention aims to provide a liquid storage dryer with uniform wall thickness around the cylinder, good sealing performance, and light weight.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A liquid storage dryer cylinder includes a cylinder and a sleeve, wherein the cylinder is disposed inside the sleeve and the cylinder has a uniform wall thickness.

[0007] One end of the cylinder is provided with a water inlet, and the water inlet has a flared structure.

[0008] The other end of the cylinder is provided with a rear cover, which is a sealed structure.

[0009] The outer wall of the cylinder near the flaring mechanism is provided with a water outlet, which is connected to a pipe and the pipe is connected to the condenser pipe.

[0010] A fixing port is provided on the outer wall of the cylinder near the rear cover, and the fixing port is connected to the condenser.

[0011] An interface is provided between the water outlet and the fixed port, and the interface is equipped with a positioning pin.

[0012] The positions of the water outlet and interface are coordinated with the positions of the condenser flow channels.

[0013] The flared structure is conical; the rear cover is flat; the outlet, interface, fixing port and sleeve are an integrated structure.

[0014] The ends of the cylinder and sleeve are rounded; the flared structure is chamfered; the outlet, interface and fixing port are cylindrical.

[0015] The cylinder is an extruded tube, and the sealing structure is an argon-arc welded cover plate.

[0016] The technical effects of this invention are as follows:

[0017] A liquid storage dryer cylinder body achieves uniform wall thickness around the circumference, enabling liquid storage and pressure resistance; the overall integrated structure provides good stability and is more robust; the rear cover is extruded, then argon arc welded and ground smooth, ensuring good sealing and facilitating changes to the condenser flow channel; the cylinder body is made of extruded tube, resulting in light weight and a corresponding reduction in the weight of the condenser assembly.

[0018] This manual includes the following figures, which illustrate the following:

[0019] Figure 1 This is a schematic diagram of a liquid storage dryer.

[0020] Figure 2 for Figure 1 A magnified schematic diagram of part A in the middle.

[0021] The markings in the diagram are: 1. Cylinder; 2. Sleeve; 3. Inlet; 4. Outlet; 5. Interface; 6. Fixing port; 7. Flared structure; 8. Rear cover; 9. Positioning pin; 10. Pipe. Detailed Implementation

[0022] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help 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 to facilitate its 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 disposed inside 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. Using an extruded profile can achieve a more uniform wall thickness, achieving liquid storage and pressure resistance performance, while reducing 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. The flared structure 7 can increase the internal volume of the cylinder 1, allowing more fluid to enter the liquid storage dryer.

[0025] The other end of the cylinder 1 is provided with a rear cover 8, which is a sealed structure. The rear cover 8 is welded by argon arc welding after being extruded. After welding, it is ground smooth to form a sealed structure. The rear cover 8 is an argon arc welded rear cover plate. The weld seam using argon arc welding has high quality, ensuring the stability of the rear cover 8 and better sealing.

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

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

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

[0029] The positions of outlet 4 and interface 5 are coordinated with the positions of the condenser flow channels. The center distance between outlet 4 and interface 5 is machined using a milling machine. Milling allows for high-precision machining because it produces fewer chips and avoids excessive thermal deformation of the workpiece, thus ensuring machining accuracy. During machining, the relative positions of outlet 4 and interface 5 are adjusted according to the position of the condenser flow channels, facilitating changes to the condenser flow channels and simplifying the condenser flow channel layout.

[0030] The flared structure 7 is conical; the rear cover 8 is flat; the outlet 4, interface 5, fixing port 6, and sleeve 2 are an integral structure. The flared structure 7 is conical with a generatrix angle of 40°; the rear cover 8 is flat for greater stability during placement, and the rear cover 4 has a wall thickness greater than 2 mm to prevent easy breakage. The integral structure of the outlet 4, interface 5, fixing port 6, and sleeve 2 provides greater stability and reduces the likelihood of damage during operation.

[0031] The ends of the cylinder 1 and sleeve 2 are rounded; the flared structure 3 is chamfered; the outlet 7, interface 8, and fixing port 9 are cylindrical. The rounded ends of the cylinder 1 and sleeve 2 remove burrs left after processing, improving safety, reducing stress concentration, and increasing fatigue strength and stress resistance. The chamfer of the flared structure 3 not only removes burrs left after processing and prevents stress concentration, but also reduces resistance during fluid flow, preventing excessive flow velocity when the fluid enters the liquid storage dryer. The cylindrical outlet 7, interface 8, and fixing port 9 are more suitable for connection to the condenser. The material of cylinder 1 is 3003-H112, and the material of sleeve 2 is aluminum alloy 4343 / 3003-H14. Cylinder 1 is made of 3003-H112, which has excellent rust resistance, good formability and weldability, and good corrosion resistance. Sleeve 2 is made of aluminum alloy 4343 / 3003-H14, which has excellent thermal conductivity, high strength and rigidity, and good processing performance.

[0032] The working principle of this invention is as follows: A liquid storage dryer cylinder includes a cylinder 1 and a sleeve 2. The cylinder 1 is manufactured using an extrusion process and is an extruded tube with uniform wall thickness. One end of the cylinder 1 has a water inlet 3, and one end of the water inlet 3 has a flared structure 7, which increases the internal area of ​​the cylinder 1. The outer wall of the cylinder 1 has a water outlet 4, an interface 5, and a fixing port 6. The water outlet 4 is connected to a condenser pipe via a pipe 10. The interface 5 has a positioning pin 9 to prevent relative movement between the cylinder 1 and the sleeve 2. The fixing port 5 secures the liquid storage dryer.

[0033] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
