Description

Technical Field

[0001] This utility model belongs to the technical field of automotive air conditioning condensers, specifically relating to an automotive air conditioning condenser with an auxiliary docking structure. Background Technology

[0002] In the automotive air conditioning refrigeration cycle, the main function of the condenser is to cool and condense the high-temperature, high-pressure gaseous refrigerant discharged from the compressor into liquid refrigerant. Through heat dissipation, the temperature and pressure of the refrigerant are reduced, preparing it for subsequent throttling and evaporation processes.

[0003] In the installation of automotive air conditioning condensers, precise assembly to the front of the radiator is crucial. However, current automotive air conditioning condensers have a significant design flaw, lacking necessary auxiliary docking structures. In practice, installers must manually hold the condenser throughout the entire process while simultaneously using one hand to grasp the fixing bolts for connection. This installation method is highly dependent on manual stability; even a slight change in the manual holding posture, or a minor wobbling, can cause a significant deviation between the condenser and the docking hole at the front of the radiator. Once the docking hole deviates, subsequent bolt tightening becomes difficult, significantly extending installation time and potentially damaging the condenser or radiator components due to forced assembly, ultimately severely impacting the overall assembly quality and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automotive air conditioning condenser with an auxiliary docking structure. This addresses the problem in existing technologies where installers must manually hold the condenser while simultaneously using one hand to grasp the bolts for connection. This installation method is highly dependent on manual stability; even a slight change in the hand's posture, or a minor wobbling, can cause a significant misalignment between the condenser and the docking hole at the front of the radiator. Misalignment makes subsequent bolt tightening difficult, significantly extending installation time and potentially damaging the condenser or radiator components due to forced assembly, ultimately severely impacting overall assembly quality and efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive air conditioning condenser with an auxiliary docking structure, comprising a connecting pipe and heat dissipation fins, wherein a fixing lug is connected to the surface of the connecting pipe, and an installation hole is provided through the surface of the connecting pipe, a fixing block is connected to the top of the fixing lug, a clamping block is provided at the bottom of the fixing block, a U-shaped groove is provided through the surface of the clamping block, a groove is provided inside the fixing block, an I-bolt is rotatably connected inside the fixing block, and a docking block is threadedly connected to the surface of the I-bolt.

[0006] As a preferred embodiment of the automotive air conditioning condenser with an auxiliary docking structure according to this utility model, the arc dimension of the U-shaped groove is adapted to the dimension of the mounting hole.

[0007] As a preferred embodiment of the present invention, an automotive air conditioning condenser with an auxiliary docking structure, the size of the docking block is adapted to the size of the groove.

[0008] As a preferred embodiment of the present invention, an automotive air conditioning condenser with an auxiliary docking structure, wherein the docking block can form a threaded transmission with the fixing block through an I-bolt, and the clamping block is connected to the docking block.

[0009] As a preferred embodiment of the automotive air conditioning condenser with an auxiliary docking structure according to this utility model, the front end of the fixing ear is connected to an arc-shaped block, and the inner wall of the arc-shaped block is interference-fitted with a first sealing gasket.

[0010] As a preferred embodiment of the present invention, an automotive air conditioning condenser with an auxiliary docking structure is provided with an assembly groove at the back end of the fixing ear, and a second sealing gasket is connected inside the assembly groove.

[0011] As a preferred embodiment of the present invention, an automotive air conditioning condenser with an auxiliary docking structure, wherein the inner diameter of the first sealing gasket is adapted to the mounting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By using a fixing block and a clamping block in conjunction, the fixing lug at the top of the automotive air conditioning condenser can be attached to the radiator's mating parts. Then, with the help of I-bolts and the mating blocks, it can accommodate radiator mating parts of different thicknesses and fix the position of the fixing lug on the radiator mating parts, ensuring that the mounting holes align with the assembly holes on the radiator mating parts. This facilitates the installation of the automotive air conditioning condenser and avoids the need for manual assembly.

[0014] The coordinated action of the arc-shaped block, the first sealing gasket, and the second sealing gasket effectively seals the connection between the mounting lug of the automotive air conditioning condenser and the radiator connector. This effectively prevents dust from seeping in through gaps between the bolts and the mounting lug, or between the mounting lug and the radiator connector, thus ensuring a tight seal and preventing dust from affecting subsequent disassembly and assembly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 The present invention provides the following technical solution: an automotive air conditioning condenser with an auxiliary docking structure, comprising a connecting pipe 1 and heat dissipation fins 2, a fixing lug 3 connected to the surface of the connecting pipe 1, an installation hole 4 through the surface of the connecting pipe 1, a fixing block 5 connected to the top of the fixing lug 3, a clamping block 6 provided at the bottom of the fixing block 5, a U-shaped groove 7 through the surface of the clamping block 6, a groove 8 inside the fixing block 5, an I-bolt 9 rotatably connected inside the fixing block 5, and a docking block 10 threadedly connected to the surface of the I-bolt 9.

[0024] In practical use, the compressor compresses the low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant and sends it to the condenser. Inside the condenser are many tiny pipes and heat sinks. As the high-temperature, high-pressure gaseous refrigerant passes through these pipes, it exchanges heat with the outside air. Due to the airflow generated by the vehicle's movement or the assistance of the fan, the heat is dissipated into the outside air, and the refrigerant temperature gradually decreases, changing from a gaseous state to a liquid state. The automotive air conditioning condenser is typically installed in front of the engine, close to the back of the front grille, in front of the radiator or water tank.

[0025] Preferably, the arc dimension of the U-shaped groove 7 is adapted to the dimension of the mounting hole 4. The dimension of the mating block 10 is adapted to the dimension of the groove 8. The mating block 10 can form a threaded transmission with the fixing block 5 through the I-bolt 9. The clamping block 6 is connected to the mating block 10.

[0026] In practical use, during the installation of the automotive air conditioning condenser, the fixing block 5 and the clamping block 6 cooperate to connect the automotive air conditioning condenser to the radiator connector. Subsequently, when the fastening bolt is removed for fixing, the fastening bolt will pass through the mounting hole 4, through the radiator connector, and continue through the U-shaped groove 7, thereby avoiding the influence of the height of the clamping block 6 on the connection between the fastening bolt and the radiator connector.

[0027] When the fixing block 5 and the clamping block 6 engage to attach the automotive air conditioning condenser to the radiator connector, the operator can manually rotate the I-bolt 9. The rotation of the I-bolt 9 causes the mating block 10 to move inside the fixing block 5. Since the mating block 10 is fitted with the groove 8, it does not rotate with the I-bolt 9. Next, the movement of the mating block 10 further moves the clamping block 6, bringing it closer to the fixing ear 3, while the distance between the clamping block 6 and the fixing ear 3 gradually decreases. This securely fixes the clamping block 6, the fixing ear 3, and the radiator connector together.

[0028] This ensures the stability of the automotive air conditioning condenser installation and allows for compatibility with radiator fittings of varying thicknesses. Therefore, it greatly simplifies the installation process, avoiding the tedious and inconvenient manual assembly.

[0029] Preferably, the front end of the fixing ear 3 is connected to an arc-shaped block 11, the inner wall of the arc-shaped block 11 is interference-fitted with a first sealing gasket 12, the back end of the fixing ear 3 is provided with an assembly groove 13, the inside of the assembly groove 13 is connected with a second sealing gasket 14, and the inner diameter of the first sealing gasket 12 is adapted to the mounting hole 4.

[0030] In practical use, during the installation of the automotive air conditioning condenser, the second sealing gasket 14 must first be inserted into the mounting slot 13, and then the first sealing gasket 12 must be installed inside the arc-shaped block 11. After the clamping block 6, the fixing ear 3, and the water tank connector are firmly fixed, the second sealing gasket 14 can seal the gap between the fixing ear 3 and the water tank connector. Subsequently, when the fastening bolt passes through the mounting hole 4 on the fixing ear 3 and fits against it, the first sealing gasket 12 will seal the gap between the fastening bolt and the fixing ear 3. In this way, dust can be effectively prevented from seeping in from the gap between the bolt and the fixing ear 3, or from the gap at the connection between the fixing ear 3 and the water tank connector, thereby ensuring the sealing of the connection and preventing dust from entering and affecting subsequent disassembly and assembly work.

[0031] Working principle: During the installation of the automotive air conditioning condenser, the second sealing gasket 14 is first inserted into the assembly groove 13, and the first sealing gasket 12 is assembled into the inside of the arc-shaped block 11. Then, the fixing block 5 and the clamping block 6 cooperate with each other to connect the automotive air conditioning condenser to the water tank docking part.

[0032] After the connection is completed, the operator can manually rotate the I-bolt 9. The rotation of the I-bolt 9 will cause the mating block 10 to move inside the fixing block 5. Since the mating block 10 is adapted to the groove 8, it will not rotate with the I-bolt 9. The movement of the mating block 10 will further drive the clamping block 6 to move, causing the clamping block 6 to move closer to the fixing ear 3. The distance between the clamping block 6 and the fixing ear 3 gradually decreases until the clamping block 6, the fixing ear 3, and the water tank connection are firmly fixed together.

[0033] Subsequently, the fastening bolts are removed and secured. The fastening bolts pass through the mounting holes 4 on the fixing lugs 3 and screw into the water tank fitting, continuing through the U-shaped grooves 7, thus avoiding the influence of the height of the clamping block 6 on the connection between the fastening bolts and the water tank fitting. When the fastening bolts are in contact with the fixing lugs 3, the first sealing gasket 12 seals the gap between the fastening bolts and the fixing lugs 3, while the previously installed second sealing gasket 14 seals the gap between the fixing lugs 3 and the water tank fitting.

[0034] This effectively prevents dust from seeping in through the gap between the bolt and the fixing lug 3, or through the gap between the fixing lug 3 and the water tank connector, thus ensuring the sealing of the connection and preventing dust from entering and affecting subsequent disassembly and assembly work.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
