Description

Technical Field

[0001] This utility model relates to the field of desiccant bottles, and in particular to a structure of an air conditioner desiccant bottle made of aluminum profile. Background Technology

[0002] Air conditioning dryer bottles are key components of automotive air conditioning systems. Their main functions are to absorb moisture from the refrigerant and filter impurities, preventing ice blockage or corrosion within the system and ensuring cooling efficiency and system lifespan. The outer shell of the air conditioning dryer bottle is typically made of aluminum alloy, which possesses good mechanical strength and pressure resistance. During production, aluminum alloy raw materials are first extruded into aluminum profiles conforming to the dimensions of the dryer bottle using an extruder and mold. These profiles are then cut into individual dryer bottle preforms according to predetermined dimensions. Next, components such as the filter and desiccant are inserted into the preforms. Finally, two end caps are welded to both ends of the dryer bottle using a welding machine, completing the manufacturing process.

[0003] With the rise of outdoor sports, desert off-roading events are becoming increasingly popular. During these events, vehicles operate under high temperatures, with the engine and air conditioning system constantly under heavy load. This causes a significant increase in refrigerant pressure within the vehicle's cooling system, leading to a faster refrigerant circulation rate.

[0004] Currently, industry improvements to automotive cooling systems for high-temperature environments primarily focus on enhancing condenser heat dissipation, employing high-performance compressors, or improving control systems. However, for the dryer bottle, a critical buffer and purification component, static design approaches are still widely adopted. The market lacks a dryer bottle that can proactively adapt to extreme environments, especially in challenging field conditions where maintenance is difficult, allowing users to quickly adjust it based on anticipated operating conditions.

[0005] This allows users to proactively increase the internal space of the dryer bottle under anticipated high-temperature operating conditions. This reduces the refrigerant flow rate, prolongs the refrigerant's residence time within the bottle, and provides greater settling space. This allows any small amounts of gas bubbles (gas-phase refrigerant) or flash gases generated by pressure changes that enter the dryer bottle when liquid refrigerant enter, sufficient time and space to rise to the top of the bottle due to density differences (gravity), thus achieving gas-liquid separation. This prevents insufficiently separated liquid refrigerant or excessive refrigerant from returning to the compressor, reducing the risk of "liquid slugging" on the compressor. Utility Model Content

[0006] This application provides an aluminum profile air conditioner dryer bottle structure, which allows for adjustment of the internal volume of the dryer bottle, enabling the dryer bottle's performance to meet the refrigerant circulation requirements of automotive air conditioning systems under high-temperature conditions.

[0007] The technical solution for the aluminum profile air conditioner dryer bottle structure provided in this application is as follows: An aluminum profile air conditioner dryer bottle structure includes an upper bottle body, a lower bottle body, and a limiting mechanism. The inner cavity of the upper bottle body is connected to the inner cavity of the lower bottle body to form a receiving cavity for containing refrigerant. A connecting pipe is provided on the upper bottle body, and a first annular groove is provided on the lower bottle body. The connecting pipe is slidably disposed in the first annular groove, so that the upper bottle body can slide relative to the lower bottle body along its axial direction to change the volume of the receiving cavity. The limiting mechanism is used to restrict the relative movement between the upper bottle and the lower bottle. The limiting mechanism includes a screw on the outer side wall of the lower bottle, two nuts threaded onto the screw, and a mating block on the outer side wall of the upper bottle. The mating block has a through hole through which the screw passes. The two nuts are located on the upper and lower sides of the mating block respectively and abut against the upper and lower ends of the mating block.

[0008] By employing the above technical solution, to increase the volume of the receiving cavity, firstly, the nut above the mating block is rotated, causing it to move upwards a predetermined distance. Then, the upper bottle is pulled, moving it away from the lower bottle. As the upper bottle moves away from the lower bottle, the volume of the receiving cavity increases. Subsequently, after the mating block moves to abut against the nut above it, the nut below the mating block is rotated, causing it to abut against the mating block. The mating block is then locked by the screw and the two nuts, thereby locking the positions of the upper and lower bottles, restricting their relative movement, and maintaining the stability of the receiving cavity volume.

[0009] Preferably, there are four screws, four mating blocks, and eight nuts. The four screws are equidistantly arranged on the periphery of the lower bottle body, and the four mating blocks are equidistantly arranged on the periphery of the upper bottle body.

[0010] By adopting the above technical solution, the screw protects the upper and lower bottles, preventing foreign objects from impacting the upper and lower bottles.

[0011] Preferably, one end of the screw extends to the top of the upper bottle body, and the other end of the screw extends to the bottom of the lower bottle body, with the upper and lower bottle bodies located between the four screws.

[0012] By adopting the above technical solution, the protective effect of the screw on the upper and lower bottle bodies can be further improved.

[0013] Preferably, four mounting blocks are provided on the outer side wall of the lower bottle body, and each of the four mounting blocks is provided with a threaded hole. The four threaded holes are respectively opposite to four through holes, and the four screws are respectively threaded into the four threaded holes.

[0014] By adopting the above technical solution, it is convenient to install the screw.

[0015] Preferably, a fixing ring is welded to the outer wall of the lower bottle body. The fixing ring is located between the lower bottle body and the four screws. An mounting plate is integrally formed on the fixing ring. The mounting plate is used to connect with the front anti-collision beam of the car.

[0016] By adopting the above technical solution, the lower bottle body is fixed to the front anti-collision beam of the car, so that when the volume of the receiving cavity is changed, it is convenient to pull the upper bottle body away from the lower bottle body.

[0017] Preferably, a sealing tube is slidably provided on the inner wall of the upper bottle along the axial direction of the upper bottle, and an annular slot is provided on the lower bottle to engage with the sealing tube; a driving component is provided inside the upper bottle, and the driving component always drives the sealing tube to move toward the lower bottle; when the upper bottle slides away from the lower bottle, the sealing tube is always inserted into the annular slot under the action of the driving component, and blocks the receiving cavity from the chamber formed between the upper bottle and the lower bottle after the upper bottle moves away from the lower bottle.

[0018] By adopting the above technical solutions, the sealing performance of the dryer bottle is improved, and the risk of coolant leakage is reduced.

[0019] Preferably, the inner wall of the upper bottle body is provided with a second annular groove, the driving component is a spring, the spring is disposed in the second annular groove, and the sealing tube isolates the second annular groove and the receiving cavity.

[0020] By adopting the above technical solution, contact between the coolant and the spring is prevented.

[0021] The main technical effects of this utility model are reflected in the following aspects: 1. This utility model uses a screw and two nuts to lock the mating block, thereby locking the positions of the upper and lower bottle bodies, restricting their relative movement, and maintaining the stability of the volume of the receiving cavity; 2. This utility model is equipped with four screws to protect the upper and lower bottle bodies and prevent foreign objects from impacting the upper and lower bottle bodies; 3. This utility model fixes the lower bottle body to the front anti-collision beam of the car, so that when changing the volume of the receiving cavity, it is convenient to pull the upper bottle body away from the lower bottle body; 4. By increasing the volume of the dryer bottle, this utility model ensures that the air conditioning refrigeration system has sufficient space to store refrigerant and perform gas-liquid separation of refrigerant under high-temperature conditions. This prevents insufficiently separated liquid refrigerant or excessive refrigerant from returning to the compressor, reducing the risk of "liquid slugging" to the compressor.

[0027] The present application will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present application can be more easily understood and mastered.

[0028] Reference Figures 1-3 This embodiment of an aluminum profile air conditioner dryer bottle structure includes an upper bottle body 1, a lower bottle body 2, and a limiting mechanism 3. The inner cavity of the upper bottle body 1 is connected to the inner cavity of the lower bottle body 2 to form a receiving cavity 4 for containing refrigerant. The upper bottle body 1 is provided with a connecting pipe 11, and the lower bottle body 2 is provided with a first annular groove 21. The connecting pipe 11 is slidably disposed in the first annular groove 21, so that the upper bottle body 1 can slide relative to the lower bottle body 2 along its axial direction to change the volume of the receiving cavity 4.

[0029] Reference Figure 2 The lower bottle 2 has a detachable filter screen 24, desiccant 25, and perforated cover 26 installed inside its inner cavity. The upper bottle 1 has an inlet pipe 13 and an outlet pipe 14 at its top. The inlet pipe 13 connects to the outside and the receiving cavity 4. The outlet pipe 14 passes through the perforated cover 26, desiccant 25, and filter screen 24 and extends into the lower bottle 2. The outlet pipe 14 connects to the receiving cavity 4 located below the filter screen 24 and the outside. When the outlet pipe 1 moves with the upper bottle 1, it will move relative to the filter screen 24 and other components.

[0030] Reference Figure 1 , Figure 3 and Figure 4Four mounting blocks 22 are welded to the outer wall of the lower bottle body 2, and four threaded holes 23 are provided on the mounting blocks 22. At the same time, a fixing ring 5 is welded to the outer wall of the lower bottle body 2. The fixing ring 5 is located below the four mounting blocks 22 and between the lower bottle body 2 and the four screws 31. An mounting plate 51 is integrally formed on the fixing ring 5. The mounting plate 51 is used to connect with the front anti-collision beam of the car.

[0031] Reference Figures 1-4 The limiting mechanism 3 is used to limit the relative movement between the upper bottle body 1 and the lower bottle body 2. The limiting mechanism 3 includes four screws 31, eight nuts 32 that are threaded to the four screws 31 in pairs, and four mating blocks 33 on the outer side wall of the upper bottle body 1. Each of the four mating blocks 33 has a through hole 34. The four through holes 34 are respectively arranged opposite to the four threaded holes 23. The four screws 31 are respectively threaded into the four threaded holes 23 and pass through the four through holes 34. The two nuts 32 on the same screw 31 are respectively located on the upper and lower sides of the corresponding mating block 33 and abut against the upper and lower ends of the mating block 33.

[0032] Reference Figure 1 Four screws 31 are equidistantly arranged on the periphery of the lower bottle body 2, and four mating blocks 33 are equidistantly arranged on the periphery of the upper bottle body 1. One end of the screw 31 extends to the top of the upper bottle body 1, and the other end of the screw 31 extends to the bottom of the lower bottle body 2. The upper bottle body 1 and the lower bottle body 2 are located between the four screws 31.

[0033] Reference Figures 1-3 A sealing tube 6 is slidably mounted on the inner wall of the upper bottle body 1 along its axial direction. An annular slot 27 is provided on the lower bottle body 2 to engage with the sealing tube 6. Initially, the end of the sealing tube 6 near the lower bottle body 2 is inserted into the annular slot 27. Simultaneously, a second annular groove 12 is provided on the inner wall of the upper bottle body 1, and the sealing tube 6 isolates the second annular groove 12 from the receiving cavity 4. A driving element 7, which is a spring 71, is provided within the second annular groove 12.

[0034] Reference Figure 2 One end of the spring 71 abuts against the top wall of the second annular groove 12, and the other end of the spring 71 abuts against the sealing tube 6. The spring 71 always drives the sealing tube 6 to move toward the lower bottle body 2. When the upper bottle body 1 slides away from the lower bottle body 2, the sealing tube 6 moves toward the lower bottle body 2 under the action of the spring 71. Therefore, it is always inserted into the annular slot 27 and blocks the receiving cavity 4 from the chamber formed between the upper bottle body 1 and the lower bottle body 2 after the upper bottle body 1 moves away from the lower bottle body 2. (Here, "the two" refers to the upper bottle body 1 and the lower bottle body 2).

[0035] Reference Figure 1 and Figure 2 The volume adjustment steps for the drying bottle receiving cavity 4 in this application are as follows: To increase the volume of the receiving cavity 4, first rotate the four nuts 32 located above the four mating blocks 33, causing the four nuts 32 to move upward a predetermined distance so that the four nuts 32 are at the same height. Then pull the upper bottle body 1 so that the upper bottle body 1 moves away from the lower bottle body 2. When the upper bottle body 1 moves away from the lower bottle body 2, the volume of the receiving cavity 4 will increase.

[0036] Subsequently, after the four mating blocks 33 move to abut against the nuts 32 located above them, the four nuts 32 located below the four mating blocks 33 are rotated so that they abut against the mating blocks 33. The mating blocks 33 are locked by the screw 31 and the two nuts 32, thereby locking the positions of the upper bottle 1 and the lower bottle 2, restricting their relative movement, and maintaining the stability of the volume of the receiving cavity 4.

[0037] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
