Technical Field

[0001] This utility model relates to the field of vehicle heat exchanger technology, and in particular to a self-cleaning heat exchanger radiator assembly. Background Technology

[0002] The vehicle heat exchanger is a key component of the automotive cooling system. It achieves heat exchange between the coolant and the air through the radiator core, thereby reducing the engine temperature. Its structure is compact and includes mechanical parts such as heat pipes, heat sinks, inlet pipes, and outlet pipes.

[0003] During vehicle operation, the coolant continuously circulates. As it passes through the radiator, dust, pollen, sand, and other impurities in the air may be drawn into the coolant. These contaminants can hinder heat exchange between the coolant and the air, leading to reduced heat dissipation efficiency. If coolant carrying impurities flows into the radiator assembly, causing poor heat dissipation, the engine is prone to overheating, which can lead to a series of malfunctions such as knocking and power loss. Severe overheating may even damage the engine and affect driving safety. Therefore, this utility model proposes a self-cleaning radiator assembly for vehicle heat exchangers to solve the above problems. Utility Model Content

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a self-cleaning radiator tube assembly for an on-board heat exchanger, including a heat exchanger 1, an inlet pipe 2, an outlet pipe 3, and a filter 4. The top of one side of the heat exchanger 1 is connected to the inlet pipe 2, and the bottom of one side of the heat exchanger 1 is connected to the outlet pipe 3. One end of the outlet pipe 3 is connected to the filter 4, and the bottom end of the filter 4 is connected to the drain pipe 5. The top of the left side of the filter 4 is connected to the feed pipe 6, and the bottom of the right side of the filter 4 is connected to the discharge pipe 17. A filter cylinder 8 is fixedly installed inside the filter 4, and a top cover 7 is fixedly installed on the top of the filter 4. A scraping mechanism is provided inside the filter 4. Coolant enters the interior of the heat exchanger 1 through the inlet pipe 2, and heat is transferred and dissipated through heat exchange to reduce the temperature of the coolant. The cooled coolant is then transported into the interior of the filter 4, where it is filtered by the filter cylinder 8 to remove impurities. Finally, it is transported to the radiator tubes in the engine through the discharge pipe 17, preventing excessive impurities in the coolant from affecting the heat dissipation efficiency of the radiator tubes.

[0020] The scraping mechanism includes a rotating shaft 9, a scraper 10, a sleeve 11, a fixing bolt 12, a nut 13, a groove 14, and a locking rod 15. The bottom of the liquid inlet pipe 2 is rotatably connected to the rotating shaft 9. The outer side of the rotating shaft 9 is provided with a scraper 10. The inside of the scraper 10 is provided with multiple sleeves 11. The bottom end of the rotating shaft 9 is fixedly connected with a fixing bolt 12. The outer side of the fixing bolt 12 is threadedly connected with a nut 13. The top sleeve 11 of the scraper 10 is provided with a groove 14. The top end of the rotating shaft 9 is symmetrically fixedly connected with locking rods 15. The top of the top cover 7 is fixedly installed with a motor 16. The output end of the motor 16 is fixedly connected to the top end of the rotating shaft 9 through a coupling. The outer side of the scraper 10 is fitted and connected to the inner side of the filter cartridge 8.

[0021] The scraper 10 is integrated with the rotating shaft 9. The top end of the rotating shaft 9 is connected to the output end of the motor 16. The motor 16 can drive the scraper 10 to rotate inside the filter cylinder 8. The scraper 10 can scrape the impurities on the inner wall of the filter cylinder 8, preventing impurities from adhering to the inner wall of the filter cylinder 8 and causing the filter holes of the filter cylinder 8 to become clogged, thus affecting the filtration effect of the filter cylinder 8.

[0022] The bottom end of the rotating shaft 9 extends through the interior of multiple sleeves 11. The outer wall of the clamping rod 15 engages with the inner wall of the groove 14. The diameter of the nut 13 is larger than the diameter of the sleeve 11. The scraper 10 is sleeved on the outside of the rotating shaft 9 through the sleeve 11, and the groove 14 on the top sleeve 11 of the scraper 10 engages with the clamping rod 15 at the top of the rotating shaft 9. Then, the nut is tightened on the outside of the fixing bolt 12. The nut and the clamping rod 15 cooperate to clamp the scraper 10 on the outside of the rotating shaft 9, thereby fixing the scraper 10 and the rotating shaft 9 together.

[0023] One end of the feed pipe 6 is inserted into the top of the filter 4 and extends to the top of the filter cylinder 8. One end of the discharge pipe 17 is parallel to the bottom of the filter cylinder 8. Both the feed pipe 6 and the discharge pipe 17 are fixedly connected to flanges. The feed pipe 6 and the discharge pipe 17 are connected to the liquid outlet pipe 3 on the heat exchanger 1 and the heat dissipation pipes by means of flanges and double-ended bolts. One end of the feed pipe 6 is located above the filter cylinder 8, so that the coolant containing impurities can be directly transported into the interior of the filter cylinder 8.

[0024] The filter 4 is provided with a collection hopper at the bottom, and the bottom of the collection hopper is connected to the top of the drain pipe 5. The drain pipe 5 is designed as a curved pipe structure. The purified coolant can be concentrated at the top of the drain pipe 5 through the collection hopper, and the coolant can be transported into the interior of the heat dissipation pipe through the drain pipe 5. The curved pipe structure can prevent the coolant from flowing back.

[0025] The top cover 7 has multiple mounting holes evenly distributed in a ring on its outer side. The top of the filter 4 has a threaded hole at the corresponding position. A connecting bolt is inserted into the mounting hole. The bottom end of the connecting bolt is threaded to the inner wall of the threaded hole. Unscrew the connecting bolt from the inside of the threaded hole and then pull it out of the mounting hole. At this time, the top cover 7 is disconnected from the top of the filter 4, and the rotating shaft 9 is connected to the liquid inlet pipe 2. By lifting the top cover 7 upward, the scraping mechanism can be removed from the filter 4 for cleaning. During the movement, the scraper 10 can be rotated to adjust its position to avoid excessive movement interference between the scraper 10 and the feed pipe 6. After cleaning, the top cover 7 is closed back on the top of the filter 4 and then installed on the top of the filter 4 using the connecting bolt.

[0026] The self-cleaning radiator tube assembly of this vehicle heat exchanger uses a sleeve 11 to attach a scraper 10 to the outside of a rotating shaft 9. The groove 14 on the sleeve 11 at the top of the scraper 10 engages with the locking rod 15 at the top of the rotating shaft 9. Then, a nut is tightened on the outside of the fixing bolt 12. The nut and the locking rod 15 work together to clamp the scraper 10 to the outside of the rotating shaft 9, thus fixing the scraper 10 and the rotating shaft 9 together. The motor 16 can drive the scraper 10 to rotate inside the filter cylinder 8. The scraper 10 can scrape away impurities on the inner wall of the filter cylinder 8, preventing impurities from adhering to the inner wall of the filter cylinder 8 and causing blockage of the filter holes, thus affecting the filtration effect of the filter cylinder 8. The coolant is filtered through the filter cylinder 8 to remove impurities. Then, it is transported to the radiator tubes in the engine through the discharge pipe 17, preventing excessive impurities in the coolant from affecting the heat dissipation efficiency of the radiator tubes.
