Technical Field

[0001] This application relates to the field of air conditioning system technology, and in particular to a drying cylinder and heat exchanger assembly. Background Technology

[0002] In the field of automotive air conditioning system technology, the dryer cartridge plays a crucial role in removing moisture and impurities from the refrigerant, and its assembly reliability with the manifold directly affects the operating efficiency and service life of the entire refrigeration system. In traditional technical solutions, the dryer cartridge mostly adopts a metal cylinder structure and is permanently assembled with the manifold through welding or other permanent connection methods.

[0003] While this type of connection can guarantee initial sealing performance, in actual use, the metal cylinder is prone to microcracks under long-term vibration and temperature changes. Welded areas are also more susceptible to stress corrosion cracking, increasing the risk of refrigerant leakage. Furthermore, the weight of metal components increases energy consumption in automobiles, making it difficult to meet the low-energy-consumption design requirements of new energy vehicles.

[0004] Therefore, it is necessary to propose a new technical solution to overcome the shortcomings of existing technologies. Utility Model Content

[0012] This application also adopts the following technical solution: a heat exchanger assembly, the heat exchanger assembly including a heat exchanger with a manifold, and a drying cylinder as described in any of the above embodiments, the drying cylinder being connected to the manifold and the flow channels between the two being interconnected.

[0033] This application proposes a drying cylinder and heat exchanger assembly suitable for automotive air conditioning systems, aiming to solve the problems of traditional metal cylinder drying cylinders being prone to micro-cracks, stress corrosion cracking at welded joints, and increased energy consumption due to their large weight under long-term vibration and temperature difference conditions. The specific embodiments of this application are described in detail below with reference to the accompanying drawings.

[0034] Please see Figures 1 to 7As shown, this application provides a drying cylinder 10 and a heat exchanger assembly for use in an air conditioning system. The drying cylinder 10 is adapted to be installed on a heat exchanger with a flow channel communicating between the two. The drying cylinder 10 includes a plastic cylinder body 1 and a drying core 13 disposed within the plastic cylinder body 1. A connecting component is provided on the plastic cylinder body 1, and the connecting component is detachably connected to the heat exchanger, so that the drying cylinder 10 and the heat exchanger are detachably connected and fixed.

[0035] The heat exchanger assembly includes the aforementioned drying cylinder 10 and a heat exchanger with a manifold 21. Specifically, the heat exchanger is, for example, a condenser in an air conditioning system. In one embodiment, the heat exchanger includes a heat exchange core comprising alternating flat tubes and heat dissipation fins. The manifold 21 is mounted on the heat exchange core and communicates with the cavity of the flat tubes. The drying cylinder 10 is mounted on the manifold 21, and the flow channels between them are connected. The connecting component is detachably connected to the manifold 21, so that the drying cylinder 10 and the manifold 21 are detachably connected and fixed.

[0036] The drying cylinder 10 provided in this application adopts a plastic cylinder body 1 structure. Compared with traditional metal cylinder bodies, the plastic cylinder body 1 has advantages such as light weight, resistance to cracking, and strong corrosion resistance, which can effectively reduce vehicle energy consumption and extend service life. At the same time, connecting parts can be easily molded directly on the plastic cylinder body 1, allowing the drying cylinder 10 and the manifold 21 to adopt a detachable connection method, which facilitates maintenance and replacement, and improves the reliability and maintainability of the entire refrigeration system.

[0037] Please see Figures 1 to 4 As shown, the plastic cylinder 1 is the main body of the drying cylinder 10, and its interior has a hollow structure. In this embodiment, the plastic cylinder 1 is injection molded from a blended modified material of polyamide 66 (PA66) and glass fiber (GF) composite material, preferably with a glass fiber composite material content of about 30%. The plastic cylinder 1 injection molded from this material has excellent thermal stability, capable of adapting to a working temperature range between -30°C and 130°C, with a heat distortion temperature ≥230°C; moreover, it has high strength and rigidity, with a tensile strength ≥150MPa, a flexural strength ≥210MPa, and an impact strength ≥6kJ / m. 2 It can meet the application requirements of air conditioning systems under different operating conditions. The density of PA66 plastic is approximately 1.25 kg / m³. 3 Compared to aluminum alloys, it achieves a weight reduction of about 30%; in addition, the raw material price of PA66 and 30%GF is more economical than that of aluminum alloys, and the injection molding cost is lower than that of metal drying cylinders that require extrusion and machining, reducing the cost of secondary processing.

[0038] Please see Figure 3As shown, furthermore, to enhance the structural strength of the plastic cylinder 1, a plurality of reinforcing ribs are integrally formed on the outer wall surface of the plastic cylinder 1. Specifically, the reinforcing ribs include annular ribs 101 circumferentially surrounding the plastic cylinder 1 and strip ribs 102 extending axially along the drying cylinder 10. The arrangement of the annular ribs 101 and strip ribs 102 can significantly improve the overall strength and rigidity of the plastic cylinder 1, enabling it to withstand greater pressure and vibration, and ensuring stability and reliability during vehicle operation. In this embodiment, the two ends of the plastic cylinder 1 are arc-shaped end faces, and radially extending reinforcing ribs 103 are also provided on the arc-shaped end faces. The arc-shaped end faces of the two ends of the plastic cylinder 1 not only increase the strength of the cylinder but also reduce stress concentration, improve the load-bearing capacity of the ends, and ensure long-term reliable operation. Radial reinforcing ribs 103 extending radially are provided on the arc-shaped end face. The radial reinforcing ribs 103 can further enhance the strength of the end of the plastic cylinder 1 and prevent deformation or damage due to stress during long-term use.

[0039] In this embodiment, the plastic cylinder 1 includes a first half-cylinder 11 and a second half-cylinder 12, and the drying core 13 is located within the cavity of the plastic cylinder 1 formed by the connection of the first half-cylinder 11 and the second half-cylinder 12. The first half-cylinder 11 and the second half-cylinder 12 are sealed together after the drying core 13 is assembled into the plastic cylinder 1. That is, during assembly, the drying core 13 is first placed in one half-cylinder, and then the other half-cylinder is aligned with it and sealed together. This split design makes the installation of the drying core 13 more convenient, and also facilitates the cleaning and maintenance of the inside of the plastic cylinder 1. In this embodiment, the end of the second half-cylinder 12 that is connected to the first half-cylinder 11 is provided with an insertion positioning part, which can be inserted into the first half-cylinder 11 for positioning, and then welding is performed. The positioning of the insertion positioning part facilitates the welding process. Of course, in other embodiments, the end faces of the two half-cylinders can be directly butted together for welding; in other embodiments, the first half-cylinder 11 and the second half-cylinder 12 can also be sealed together by connecting parts such as threads and snaps, and in conjunction with sealing rings.

[0040] Please see Figure 3 and Figure 6As shown, in this embodiment, at least one of the first half-cylinder 11 and the second half-cylinder 12 has a guide section 123 inside to guide the fluid to flow toward the drying core 13. The design of the guide section 123 allows the fluid to flow more smoothly through the drying core 13, improving the drying effect and ensuring that moisture and impurities in the refrigerant can be fully removed. In this embodiment, a connection port 120 for communicating with the manifold 21 is opened on the second half-cylinder 12. The connection port 120 specifically includes an inlet and an outlet. The guide section 123 is also disposed inside the second half-cylinder 12, and the guide section 123 is a guide pipe that communicates with the inlet of the connection port 120.

[0041] In this embodiment, the drying core 13 is disposed inside the plastic cylinder 1, and its main function is to remove moisture and impurities from the refrigerant. The drying core 13 is typically made of a material with good hygroscopic and filtration properties; in this embodiment, it is specifically a molecular sieve. Molecular sieves have a uniform microporous structure, which can selectively adsorb moisture and impurities while having minimal impact on the performance of the refrigerant.

[0042] Please see Figures 2 to 4 As shown, a connecting component is provided on the outer wall of the plastic cylinder 1. In this embodiment, the connecting component can be integrally injection molded with the plastic cylinder 1, and the connecting component is used to detachably connect and fix it to the manifold 21. The design of the connecting component makes the installation and disassembly of the drying cylinder 10 more convenient and quick, improving assembly efficiency. In some embodiments, the connecting component includes one or more of the following: screw connection part 111, elastic clamping arm 112, and elastic buckle 122. In other embodiments, the connecting component can also be set as a separate part from the plastic cylinder 1, for example, as a clamp independent of the plastic cylinder 1, which can connect and fix the plastic cylinder 1 to the manifold 21.

[0043] Specifically, such as Figure 3 and Figure 4 As shown, the connecting component includes a screw connection portion 111, which has screw holes. A screw connection post 22, corresponding to the screw holes, is fixed on the manifold 21. In this embodiment, the screw connection post 22 is welded to the manifold 21; in other embodiments, it may be formed on the manifold 21 by riveting or integral molding. During connection, the drying cylinder 10 is fixedly connected to the manifold 21 by passing a screw 14 through the screw holes in the screw connection portion 111 and locking it to the screw connection post 22. In this embodiment, there are two screw connection portions 111, located at both ends of the plastic cylinder 1.

[0044] The screw connection method offers advantages such as a strong and reliable connection, capable of withstanding significant tensile forces and vibrations, ensuring a stable connection between the drying cylinder 10 and the manifold 21. The design of the screw connection part 111 makes the installation and disassembly of the drying cylinder 10 more convenient; assembly or disassembly can be completed simply by tightening or loosening the screw 14. Furthermore, the screw connection method also offers a degree of adjustability; by adjusting the tightness of the screw 14, the connection tightness between the drying cylinder 10 and the manifold 21 can be controlled, ensuring sealing performance.

[0045] Please refer to the following: Figure 5 As shown, in this embodiment, the connecting component further includes elastic clamping arms 112, which clamp the two sides of the manifold 21 to hold it tightly. The elastic clamping arms 112 are cantilevered arms extending downwards from the plastic cylinder 1, possessing a certain degree of flexibility and elastic deformation capability. There is a pair of elastic clamping arms 112, with their opposite sides configured to match the manifold 21, such as being configured as arc-shaped concave surfaces. During assembly, the drying cylinder 10 is brought close to the manifold 21, causing the elastic clamping arms 112 to open and clamp the two sides of the manifold 21. After installation, the elastic clamping arms 112, under their own elastic force, hold the manifold 21 tightly, thus connecting the drying cylinder 10 and the manifold 21.

[0046] The connection method using the elastic clamping arm 112 offers advantages such as convenient and quick installation, allowing assembly to be completed without tools. Simultaneously, the elastic deformation capacity of the elastic clamping arm 112 can adapt to different sizes of manifolds 21, providing a degree of versatility. Furthermore, the elastic clamping arm 112 also acts as a buffer and shock absorber, reducing the impact of vibrations during vehicle operation on the connection between the drying cylinder 10 and the manifold 21, thus improving connection reliability. In this embodiment, both the elastic clamping arm 112 and the screw connection part 111 are used for connection, making the connection more reliable. Moreover, the connection of the elastic clamping arm 112 can provide initial positioning, facilitating the tightening operation when the screw 14 passes through the screw connection part 111 and connects to the screw connection post 22.

[0047] Please refer to the following: Figure 6 As shown, in this embodiment, the connecting component includes an elastic buckle 122, and a corresponding engaging and engaging retaining part 2411 is fixed on the manifold 21. During assembly, the elastic buckle 122 of the drying cylinder 10 is aligned with the retaining part 2411 on the manifold 21, and then the drying cylinder 10 is pressed down forcefully, causing the elastic buckle 122 to elastically deform and engage with the retaining part 2411, thereby connecting the drying cylinder 10 and the manifold 21.

[0048] The connection method using the elastic buckle 122 has the advantages of a firm connection and easy disassembly. When it is necessary to disassemble the drying cylinder 10, simply pull the drying cylinder 10 outward to disengage the elastic buckle 122 from the holding part. At the same time, the design of the elastic buckle 122 can also prevent the drying cylinder 10 from loosening or falling off due to vibration during vehicle operation, ensuring the safety of the connection.

[0049] like Figure 6 and Figure 7 As shown, in this embodiment, the manifold 21 has two connection holes 210, which are respectively connected to two connection ports 120 on the drying cylinder 10 to realize the input and output of refrigerant. Figure 7 As indicated by the middle arrow, the manifold 21 is fixed with an interface component 24, which connects the connection hole 210 and the connection port 120, i.e., it connects the drying cylinder 10 and the manifold 21. In this embodiment, the interface component 24 includes a base portion 241 and an interface post 242 extending from the base portion 241 for sealing insertion into the drying cylinder 10. The base portion 241 forms the retaining portion 2411. In this embodiment, the interface component 24 is a connecting flange, and its base portion 241 is fixedly connected to the manifold 21 by welding, riveting, or integral molding. The retaining portions 2411 protrude outward from both sides of the base portion 241. The design of the interface post 242 ensures smooth flow between the drying cylinder 10 and the manifold 21, while the sealed insertion between the interface post 242 and the drying cylinder 10 prevents refrigerant leakage. In this embodiment, a sealing ring is fitted around the circumference of the interface post 242 to achieve a sealed connection with the drying cylinder 10. Multiple sealing rings can be provided along the axial direction of the interface post 242 to enhance sealing performance. In this embodiment, two sealing rings are fitted on each interface post 242 to achieve a double-layer seal. The interface component 24 makes the connection structure more compact, improving the reliability and sealing performance of the entire heat exchanger assembly.

[0050] During assembly, the drying cylinder 10 is pressed onto the manifold 21 with the elastic clamping arm 112 and elastic buckle 122 facing the manifold 21. During the pressing process, the elastic clamping arm 112 and elastic buckle 122 elastically deform and open, and after being installed in place, they return to their original position by their own elastic force to clamp and hold at the corresponding position of the manifold 21. Then, the screw 14 is passed through the screw connection part 111 and locked onto the screw connection post 22 to complete the assembly of the drying cylinder 10 and the manifold 21.

[0051] In use, when the automotive air conditioning system is running, refrigerant flows from the manifold 21 into the dryer cylinder 10. The refrigerant first enters the interior of the dryer cylinder 10 through the interface post 242 of the interface component 24, and then flows evenly through the dryer core 13 under the guidance of the guide section 123. The molecular sieve and other materials in the dryer core 13 adsorb and filter the moisture and impurities in the refrigerant, thus purifying and drying the refrigerant. After drying, the refrigerant flows out from the other end of the dryer cylinder 10 back into the manifold 21 to continue participating in the air conditioning system's circulation.

[0052] As can be seen from the above description of the specific embodiments, this application uses a plastic cylinder 1 instead of a traditional metal cylinder, which greatly reduces the weight of the dryer cylinder 10, thereby reducing the energy consumption of the vehicle and meeting the design requirements of new energy vehicles for low energy consumption. Moreover, the plastic cylinder 1 has good corrosion resistance, resisting the erosion of refrigerant and the external environment during long-term use, and is less prone to problems such as micro-cracks and stress corrosion cracking, thus extending the service life of the dryer cylinder 10. In addition, by setting various detachable connecting parts, such as screw connections 111, elastic clamping arms 112, and elastic buckles 122, a reliable connection between the dryer cylinder 10 and the manifold 21 is achieved. These connection methods are not only convenient to install and disassemble, but also able to withstand the vibration and tension during vehicle operation, ensuring the stability of the connection. Because the dryer cylinder 10 and the manifold 21 are connected in a detachable manner, when the drying core 13 fails or the plastic cylinder 1 needs cleaning and maintenance, the dryer cylinder 10 can be easily disassembled for replacement or repair, improving the maintainability of the entire refrigeration system. Furthermore, the design of the flow guide 123 allows the refrigerant to flow evenly through the drying core 13, improving drying efficiency and ensuring that moisture and impurities in the refrigerant can be fully removed, thereby improving the cooling effect and operational stability of the air conditioning system.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
