Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, specifically to an automotive air conditioning condenser. Background Technology

[0002] The automotive air conditioning condenser is the core heat dissipation component of the automotive air conditioning refrigeration system. It is essentially a heat exchanger responsible for releasing heat from inside the vehicle to the atmosphere. It is the key to whether the air conditioning can cool. Common types of condensers include parallel flow, tube-fin, and tube-plate. In existing technologies, parallel flow condensers have high heat exchange efficiency, but due to the multiple pipe channels inside, impurities are easily trapped. Cleaning requires the entire condenser to be disassembled and the outlet of the condenser's liquid collection pipe to be blocked before spraying cleaning fluid into the inlet of the liquid collection pipe. This operation makes it inconvenient to control the opening and closing of the discharge port to control the gas pressure inside the condenser, resulting in low cleaning efficiency. To address these shortcomings, we propose an automotive air conditioning condenser. Summary of the Invention

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1 to 7 The present invention provides a technical solution: including a plate body 1, mounting buckles 2 are symmetrically arranged on both sides of the top of the plate body 1, and a collection pipe 3 is respectively connected to the side of the plate body 1. A side cylinder 4 is connected to the back of one of the collection pipes 3. An inlet pipe 5 and an outlet pipe 6 are respectively connected to one of the collection pipes 3 away from the side cylinder 4. A three-way fitting 7 is respectively connected to the inlet pipe 5 and the outlet pipe 6. A mounting bracket 8 is fixedly connected to one of the collection pipes 3 on the back of the three-way fitting 7. A drive cylinder 9 is provided on the mounting frame 8. The output shaft of the drive cylinder 9 passes through the mounting frame 8 and is fixedly connected to a support seat 10. The support seat 10 is slidably connected to the mounting frame 8. A cleaning liquid tank 11 is detachably installed on the support 10. The top of the cleaning liquid tank 11 is provided with a first plug 12 that is fixedly connected to the support 10. The first plug 12 is movably connected to one of the three-way fittings 7. A spray valve 13 is provided on the first plug 12. The spray valve 13 passes through the interior of the first plug 12 and communicates with the interior of the cleaning liquid tank 11. An air valve interface 14 is provided at the input end of the cleaning liquid tank 11. The air valve interface 14 is used to connect to a gas pressurization output device. In this embodiment, the gas supply equipment is started and high-pressure gas is input into the cleaning liquid tank 11. The cleaning liquid is released under pressure to the spray valve 13. The spray valve 13 is opened and passes through the liquid inlet pipe 5 to conduct the cleaning liquid into the plate 1. The cleaning liquid flows along the pipeline in the parallel flow condenser to clean the impurities inside. The impurities are impacted by the cleaning liquid and flow to the liquid outlet pipe 6. The bottom of the support 10 is fixedly connected to a second plug 15, and a blocking cage 16 is fixedly connected to the second plug 15. A pressure sensor 17 is fixedly connected to one end of the blocking cage 16 relative to the second plug 15. The second plug 15 and the blocking cage 16 are internally movably connected to another tee 7. In this embodiment, when cleaning the condenser, the pipes connecting the front ends of the two tee fittings 7 are first removed. In the initial state, the first plug 12 and the second plug 15 are not inside the two tee fittings 7. The side of the two tee fittings 7 near the two plugs is sealed by the plug 22. After the pipes are removed, the gas delivery equipment is connected to the gas valve interface 14, the drive cylinder 9 outputs outward, and the transmission bearing seat 10 moves closer to the two tee fittings 7. During the process, the first plug 12 and the second plug 15 enter the interior of the two tee fittings 7 respectively, and the two plugs 22 block one end of the pipe connecting the tee fittings 7, thus completing the switching of the operating state. The top of the second plug 15 is fixedly connected to a driving component 18, such as a cylinder. The output end of the driving component 18 is engaged with and driven by an adjusting disc 19. The surface of the adjusting disc 19 is provided with several guide grooves 20 that are opened through and around it. Inserts 21 are slidably arranged in the guide grooves 20. There are four inserts 21 arranged in a ring and they are spliced ​​together. The inserts 21 are slidably connected to the surface of the second plug 15. In this embodiment, during the cleaning process, based on the pressure display of the pressure sensor 17, the controller controls the operation of the drive unit 18. First, the drive unit 18 drives the adjustment plate 19 to bring the four inserts 21 closer together, sealing the opening of the second plug 15, so that the inside of the plate 1 gradually accumulates pressure. When the pressure value displayed by the pressure sensor 17 reaches the release threshold, the controller causes the drive unit 18 to drive the adjustment plate 19 to reverse, and the four inserts 21 are opened synchronously through the guide groove 20. Since there is an opening at the far end, the pressure inside the plate 1 flows quickly towards that end and is released, so that the stubborn impurities attached to the pipeline inside the plate 1 are carried out together. The opening diameter of the second plug 15 can also be controlled by controlling the movement of the inserts 21, thereby adjusting the flow rate of the cleaning fluid and controlling the duration of the cleaning fluid in the plate 1, further improving the cleaning effect. Both the first plug 12 and the intercepting cage 16 are fixedly connected with plug pieces 22, which abut against both sides of the inner surface of the tee 7, and are used to block either side of the tee 7. A guide rod 23 is fixedly connected to one side of the top of the support 10; A desiccant 24 is detachably installed inside the side cylinder 4. A sealing plate 25 is installed on the outside of the desiccant 24. The sealing plate 25 is installed inside the side cylinder 4. The top of the sealing plate 25 passes through the side cylinder 4 and is fixedly connected to a gear 26. A crossbar 27 is installed on the side of the gear 26. The crossbar 27 is slidably connected to the plate body 1. A rack 28 is fixedly connected to the side of the crossbar 27 near the gear 26. The rack 28 meshes with the gear 26. An elastic element 29 is provided at the top of the end of the crossbar 27 away from the gear 26, and the crossbar 27 abuts against the elastic element 29, which is preferably a spring; A stop shaft 30 is fixedly connected to one end of the crossbar 27. A swing arm 31 abuts against the side of the stop shaft 30. The end of the swing arm 31 away from the stop shaft 30 is hinged to the mounting bracket 8. The surface of the swing arm 31 abuts against the transmission rod 23. In this embodiment, while the support seat 10 moves toward the two tee members 7, the transmission rod 23 contacts the swing arm 31 at the connection between the swing arm 31 and the mounting bracket 8, and continuously pushes the swing arm 31, causing the other end of the swing arm 31 to swing around its hinge with the mounting bracket 8, thereby pushing the stop shaft 30 laterally along the length of the plate 1. The stop shaft 30 laterally pushes the crossbar 27, compressing the elastic member 29. The rack 28 at the other end of the crossbar 27 meshes with the gear 26, thereby causing the sealing plate 25 at the bottom of the gear 26 to rotate, sealing the connection between the side cylinder 4 and the nearby collection pipe 3, preventing the cleaning liquid from flowing into the side cylinder 4 along the pipe of the plate 1, and protecting the desiccant 24. After the cleaning process is completed, the support seat 10 retracts, and the sealing plate 25 automatically removes the obstruction between the side cylinder 4 and the collection pipe 3.

[0016] The method of use and advantages of this invention: The working process of this automotive air conditioning condenser is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown: S1: Remove the front end pipe of the tee fitting 7, drive the cylinder 9 to move the bearing seat 10 forward along the width direction of the plate 1, so that the first plug 12 and the second plug 15 are inserted into the tee fitting 7, and the pipe interface is sealed by the plug plate 22. S2: High-pressure gas is used to send the cleaning liquid in the cleaning liquid tank 11 into the condenser plate 1 through the spray valve 13 and the liquid inlet pipe 5 to flush out impurities in the pipeline and discharge it through the liquid outlet pipe 6. S3: Based on the signal from the pressure sensor 17, the controller controls the drive component 18 to drive the insert 21 to open and close the second plug 15, thereby achieving pressure accumulation and instantaneous pressure release in the plate 1, flushing out stubborn impurities, and controlling the flow rate and residence time by adjusting the opening size. S4: When the carrier seat 10 moves forward, the linkage sealing plate 25 rotates to seal the side cylinder 4 and the manifold 3 to protect the desiccant. After cleaning, the carrier seat 10 retracts and the sealing plate 25 resets.
