Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, and in particular to a KOMO tube and condenser. Background Technology

[0002] As the proportion of new energy vehicles in the passenger car market continues to increase, in order to reduce the overall energy consumption of the vehicle as much as possible to improve the range and enhance the driving comfort of the passenger cabin, heat pump air conditioning systems have gradually become the standard configuration of passenger car passenger cabin air conditioning systems, and the condenser in the heat pump air conditioning system is the key heat exchange equipment of the passenger cabin air conditioning system.

[0003] To ensure the condenser can adapt to different operating conditions, KOMO tubing (KOMO is a well-known term in this field, derived from German, meaning "a liquid receiver for storing desiccant") is generally installed on the condenser to store or release refrigerant in the heat pump air conditioning system, maintaining refrigerant balance within the system. Traditional KOMO tubing is mostly a one-piece structure, which is difficult to manufacture and has limited versatility for different installation conditions. Furthermore, the ends of KOMO tubing are typically sealed with plugs, and the plugs are usually connected to the KOMO tubing via interference fits. This connection method has poor pressure resistance, affecting the sealing performance of the KOMO tubing.

[0004] Therefore, there is an urgent need to propose a KOMO tube and condenser to solve the above-mentioned technical problems. Utility Model Content

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] This embodiment provides a KOMO tube with a split-type structural design, which reduces the processing difficulty, improves the versatility of the KOMO tube, and provides better sealing performance.

[0041] Specifically, such as Figures 1-3 As shown, the KOMO tube includes a cylinder 100 and a sealing assembly 200. The sealing assembly 200 includes a sealing seat 210, a plug 220, and a stop 230.

[0042] The sealing seat 210 has a through hole 211 extending along its axial direction. One end of the cylinder 100 is connected to the first end of the sealing seat 210 and communicates with the through hole 211. At the second end of the sealing seat 210, a groove 212 is provided on the inner peripheral wall of the through hole 211. A plug 220 is installed in the through hole 211 for sealing. A stop 230 is engaged in the groove 212, and the end of the plug 220 away from the cylinder 100 can abut against the stop 230.

[0043] By designing the cylinder 100 and sealing assembly 200 as separate structures, the sealing assembly 200 can be assembled first, followed by its connection to the cylinder 100. Compared to the integrated structure of KOMO tubes in the prior art, this effectively reduces processing and assembly difficulty, improves the controllability of the production process, and thus contributes to increased production efficiency. Furthermore, a suitable length of cylinder 100 can be selected to fit the same sealing assembly 200 according to different installation boundaries and different subcooling requirements, improving the versatility of the KOMO tube. Additionally, the stop 230 limits the plug 220, improving its pressure resistance and thus enhancing the reliability of its sealing performance. Moreover, the stop 230 is installed via a slot 212, resulting in a simple structure and easy assembly.

[0044] Optionally, such as Figure 4As shown, in one possible embodiment, the stop 230 includes an open retaining ring 231 and multiple bosses 232. The open retaining ring 231 is engaged within a slot 212, and the two ends of the open end of the retaining ring 231 can elastically move closer or further apart. This arrangement facilitates the installation of the stop 230 within the through hole 211 and improves the reliability of the engagement between the open retaining ring 231 and the slot 212. Multiple bosses 232 are disposed on the inner peripheral wall of the open retaining ring 231 and spaced circumferentially along the open retaining ring 231. The end of the plug 220 furthest from the cylinder 100 can abut against a boss 232. This stop 230 has a simple structure, is easy to install, and provides good reliability in limiting the plug 220.

[0045] Further, see also Figure 4 To facilitate the installation of the stop 230, a clamping hole 233 can be provided on the open retaining ring 231. The clamping hole 233 is used to cooperate with the clamp. Optionally, in this embodiment, clamping holes 233 are provided at both ends of the opening of the open retaining ring 231.

[0046] The installation steps for the stop 230 are as follows:

[0047] First, the two clamping holes 233 on the open retaining ring 231 are clamped by the clamp, and the two ends of the opening of the open retaining ring 231 are brought closer to each other by the clamp to reduce the overall size of the stop 230, so that the stop 230 can be moved into the through hole 211 later.

[0048] Then, move the stop 230 to the slot 212 position in the through hole 211, and put the open retaining ring 231 into the slot 212;

[0049] Finally, the control clamp is disengaged from the clamping hole 233. At this time, the open retaining ring 231 can reliably engage with the slot 212 under the action of elastic restoring force.

[0050] It is understandable that the shape of the slot 212 is adapted to the shape of the open retaining ring 231 to ensure the reliability of the snap-fit ​​between the slot 212 and the open retaining ring 231.

[0051] It is understandable that the number and size of the bosses 232 can be set according to actual needs. In one possible embodiment, the number and size of the bosses 232, as well as the specific size of the opening retaining ring 231, can be determined using CAE (Computer Aided Engineering) simulation analysis to meet the usage requirements of different working conditions.

[0052] Optionally, in one possible embodiment, the width of the open retaining ring 231 gradually decreases from the middle to both ends. This configuration can improve the elastic deformation capacity at both ends of the open retaining ring 231. At the same time, the wider design in the middle of the open retaining ring 231 can also improve the structural strength of the open retaining ring 231 and reduce the risk of damage to the open retaining ring 231 during assembly.

[0053] Further, see also Figure 2 and Figure 3 The plug 220 has an annular groove 221 on its outer peripheral wall, and a sealing ring 240 is installed in the annular groove 221. The portion of the sealing ring 240 protruding from the annular groove 221 elastically abuts against the inner peripheral wall of the through hole 211. By setting the sealing ring 240 between the plug 220 and the through hole 211, the reliability of the plug 220 in sealing the through hole 211 is improved, and the sealing performance of the sealing assembly 200 is further improved.

[0054] Optionally, the number of annular grooves 221 provided on the outer peripheral wall of the plug 220 can be one, two, etc., and each annular groove 221 corresponds to a sealing ring 240. The number of annular grooves 221 can be set according to the sealing requirements, and this application does not make a specific limitation.

[0055] Optionally, see [link to relevant documentation] Figure 2 In one possible embodiment, the first end of the sealing seat 210 is provided with a mounting hole communicating with the through hole 211. One end of the cylinder 100 is inserted into the mounting hole, and the outer peripheral wall of the cylinder 100 is welded to the inner peripheral wall of the mounting hole. That is, when installing the cylinder 100 and the sealing assembly 200, one end of the cylinder 100 is first inserted into the mounting hole to pre-fix the cylinder 100, and then the welding between the cylinder 100 and the sealing seat 210 is performed. The assembly difficulty is low, and the connection strength and sealing performance between the cylinder 100 and the sealing seat 210 are high.

[0056] Further, see also Figure 2 and Figure 3 The sealing assembly 200 also includes a plug 250, which includes a cover body 251 and a connecting post 252. The cover body 251 seals the end of the through hole 211, and the connecting post 252 is connected to the connecting hole 222 on the plug 220. A stop member 230 is located between the plug 220 and the plug 250. By providing the plug 250 to seal the end of the connecting hole 222, the sealing performance of the sealing assembly 200 is further improved. The plug 250 is fixed by the cooperation of the connecting post 252 and the connecting hole 222, which has a simple structure and facilitates the assembly of the plug 250.

[0057] Optionally, an external thread can be provided on the connecting post 252, and the connecting hole 222 can be configured as a threaded hole. The connecting post 252 is threadedly connected to the threaded hole to connect the plug 250 and the plug 220. This configuration has a simple structure, facilitates the assembly of the plug 250, and provides better reliability in the connection between the plug 250 and the plug 220.

[0058] Further, see also Figure 2 In one possible embodiment, the cover 251 includes a first ring portion 2511 and a second ring portion 2512 spaced apart. The outer edge of the first ring portion 2511 abuts against the end face of the second end of the sealing seat 210, and the outer edge of the second ring portion 2512 elastically abuts against the inner peripheral wall of the through hole 211. The cover 251 forms two sealing structures through the first ring portion 2511 and the second ring portion 2512, resulting in high sealing performance and significantly improving the sealing performance of the KOMO tube.

[0059] Alternatively, the first ring portion 2511 and the second ring portion 2512 can be formed by opening an annular groove on the outer periphery of the cover 251, which simplifies the processing.

[0060] It is worth noting that the thickness of the second ring 2512 can be made thinner to ensure the elasticity of the second ring 2512.

[0061] Optionally, the cover 250 is made of plastic.

[0062] Further, see also Figures 1-3 The sealing seat 210 is provided with an integrally formed first mounting bracket 213, and the end of the cylinder 100 away from the sealing seat 210 is provided with a second mounting bracket 300. The first mounting bracket 213 and the second mounting bracket 300 are used for the assembly of the KOMO tube. By providing an integrally formed first mounting bracket 213 on the sealing seat 210, the process of welding the first mounting bracket 213 to the cylinder 100 is eliminated, and the structural stability of the first mounting bracket 213 integrally formed with the sealing seat 210 is higher. Through the cooperation of the first mounting bracket 213 and the second mounting bracket 300, the stress on the KOMO tube can be more even, improving the reliability of the KOMO tube assembly.

[0063] Optionally, in one possible embodiment, the first mounting bracket 213 includes two connecting ears, each with a mounting hole. In other embodiments, the structure of the first mounting bracket 213 can also be configured differently, depending on actual needs, and this application does not impose specific limitations.

[0064] Optionally, in one possible embodiment, the second mounting bracket 300 also includes a connecting ear, which is also provided with a mounting hole. In other embodiments, the structure of the second mounting bracket 300 can also be configured differently, depending on actual needs, and this application does not impose specific limitations.

[0065] Further, see also Figure 1 The sealing seat 210 has a first arc surface 214 on the side away from the first mounting bracket 213. The first arc surface 214 is used to connect with the outer peripheral wall of the condenser's manifold 11. The second mounting bracket 300 has a second arc surface 310 on one side, which is also used to connect with the outer peripheral wall of the manifold 11. By connecting the first arc surface 214 and the second arc surface 310 with the outer peripheral wall of the manifold 11, the contact area between the sealing seat 210 and the manifold 11, as well as between the second mounting bracket 300 and the manifold 11, is increased.

[0066] Optionally, the first arc surface 214 and the second arc surface 310 can be connected to the manifold 11 by welding. The welding process is simple and the connection strength is high.

[0067] Optionally, see [link to relevant documentation] Figure 1 The sealing seat 210 is provided with a first flow channel 215 connecting the manifold 11 and the through hole 211, and the second mounting bracket 300 is provided with a second flow channel 320 connecting the manifold 11 and the cylinder 100. The first flow channel 215 and the second flow channel 320 can be used to store the refrigerant.

[0068] like Figure 6 As shown, this embodiment also provides a condenser, including a condenser body 10 and the aforementioned KOMO tube, wherein the KOMO tube is disposed on one side of the condenser body 10.

[0069] Because this condenser uses the aforementioned KOMO tubes, its processing and assembly are relatively simple, and its operational reliability is excellent.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
