Description

Technical Field

[0001] This utility model relates to the field of aluminum flat tube technology, and in particular to a gradient cooling and drying mechanism for microchannel aluminum flat tubes. Background Technology

[0002] Microchannel aluminum flat tubes are flat tubes with microchannel structures made of aluminum alloy. Their channel size is at the micrometer level. They are generally manufactured using a special extrusion process and have the advantages of being lightweight, having high heat exchange efficiency, and being corrosion resistant. They are widely used in automotive air conditioning, household air conditioning, and heat exchanger refrigeration and thermal management fields, and can effectively improve system performance and energy utilization efficiency.

[0003] The gradient cooling and drying mechanism for microchannel aluminum flat tubes is a component used in the production process of microchannel aluminum flat tubes. It primarily cools and dries aluminum flat tubes after hot extrusion or other processes. The mechanism mainly consists of a cooling unit and a drying unit. The cooling unit circulates and controls the temperature of cooling water through a water tank, circulation pipeline, temperature monitoring components, heat exchange components, and switching components to achieve gradient cooling of the flat tubes and ensure effective cooling. The drying unit uses multiple nozzles positioned opposite the flat tubes, combined with guide components, to create an acute angle between the airflow direction of the flat tubes and the nozzles, increasing the blowing area on the flat tube surface and effectively improving drying efficiency while reducing energy consumption. However, even after processing by the drying mechanism, in some special cases, such as when the aluminum flat tube surface has tiny grooves or pores, or when the drying process is incomplete, the drying process may still fail. Uneven airflow distribution and residual moisture can lead to oxidation and corrosion of the aluminum flat tube surface during subsequent storage or processing, affecting product quality. Current technology aims to minimize contact between the aluminum flat tube and water or other corrosive substances during processing. If cleaning is necessary, timely drying after cleaning is crucial. Furthermore, optimizing processing steps reduces the exposure time of the aluminum flat tube to air, lowering the risk of oxidation and corrosion. However, during use, changes in the specifications of the produced aluminum flat tubes (e.g., length, width, or diameter) prevent the fixed nozzles from being adjusted to the new product's size and shape, hindering the provision of adequate cooling. This necessitates redesigning or modifying the entire cooling system, increasing production costs and time. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a microchannel aluminum flat tube gradient cooling and drying mechanism, which aims to improve the problem in the prior art where, when the specifications of the produced aluminum flat tubes change, such as different lengths, widths, or tube diameters, the fixed nozzles cannot be adjusted according to the size and shape of the new products, making it difficult to provide a suitable cooling effect. This requires redesigning or modifying the entire cooling system, which increases production costs and production cycles.

[0030] 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a microchannel aluminum flat tube gradient cooling and drying mechanism, comprising a body 1, a conveyor belt 3 installed in the middle of the inner side of the body 1, a water tank 6 fixedly connected to the top of the body 1, a water inlet pipe 7 connected to the top left side of the water tank 6, connecting hoses 23 connected to the left and right ends of the bottom of the water tank 6, multiple nozzles 24 equidistantly arranged at the bottom of the connecting hoses 23, a second motor 18 installed in the middle of the rear side of the water tank 6, providing power to subsequent processes through the installation of the second motor 18, a connecting short column 28 fixedly connected to the output end of the second motor 18, a gear 27 fixedly connected to the outer side of the connecting short column 28, and the upper and lower rear sides of the water tank 6... Both ends are slidably connected with racks 26, the outer side of racks 26 meshes with the outer side of gears 27, and the front side of each rack 26 is fixedly connected with a connecting rod 25. The front side of the connecting rod 25 is fixedly connected with the rear side of the connecting hose 23. A clamping mechanism 2 is installed inside the body 1. The clamping mechanism 2 is used to clamp the aluminum flat tube. A circular cover 8 is installed on the top of the water inlet pipe 7. A fixed short column 9 is fixedly connected to the top center of the circular cover 8. The installation of the circular cover 8 prevents dirt from entering. Multiple fans 10 are installed at equal intervals on the outer side of the body 1. Multiple heat dissipation slots 17 are opened at equal intervals on the right side of the body 1. By turning on the fans 10, the aluminum flat tube can be dried quickly.

[0032] Specifically, the aluminum flat tube can be moved by the installation of the conveyor belt 3. The water tank 6 receives water through the water inlet pipe 7 on its top left side. When the cooling process needs to be started, the second motor 18 is turned on. Its output end drives the gear 27 fixedly connected on the outside to start rotating through the connecting short column 28. The two racks 26 mesh with the gear 27 for transmission. As the racks 26 rotate, the connecting rod 25 fixedly connected on the front side also starts to move, thereby pulling the connecting hose 23 to make a corresponding displacement. This allows the nozzle 24 to spray water evenly on the microchannel aluminum flat tube on the conveyor belt 3, ensuring the uniformity of the cooling process, thus completing the gradient cooling process and improving the working efficiency of the cooling and drying process.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The clamping mechanism 2 includes a first motor 201, which is installed at the bottom right side of the machine body 1. A rotating short column 202 is fixedly connected to the output end of the first motor 201. A connecting rope 203 is fixedly connected to the front and rear ends of the rotating short column 202. A clamping plate 204 is fixedly connected to the left side of each of the two connecting ropes 203. The bottom of the clamping plate 204 is slidably connected to the top of the conveyor belt 3. A spring 205 is fixedly connected to the left and right ends of the two clamping plates 204 on opposite sides. The clamping plate 204 can be quickly reset by the installation of the spring 205. A telescopic tube 206 is installed on the outside of the spring 205. A sliding groove 207 is opened in the middle of the left and right ends of the machine body 1. A support rod 5 is fixedly connected to the front and rear ends of the bottom right side of the machine body 1. A support plate 4 is fixedly connected to the top of the support rod 5.

[0034] Specifically, the first motor 201 is started, and its output end is connected to the rotating short column 202. The rotating short column 202 rotates accordingly, which in turn drives the connecting rope 203 to wind around. The connecting rope 203 pulls the clamping plate 204 fixed on the left side, so that its bottom slides on the top of the conveyor belt 3. The two clamping plates 204 move relative to each other and clamp the aluminum flat tube. With the installation of the spring 205 and the assistance of the telescopic tube 206, the device can achieve buffering and quick reset. The sliding groove 207 is provided in the middle of the left and right ends of the machine body 1 to guide the movement of the clamping plate 204. The conveyor belt 3 begins to transport the clamped aluminum flat tube. Through the above process, unnecessary movement of the aluminum flat tube during the transportation process is avoided.

[0035] Reference Figure 1 , Figure 2 and Figure 3A slot plate 12 is fixedly connected to the middle of the front side of the body 1. A notice board 11 is set inside the slot plate 12. A storage box 13 is fixedly connected to the lower middle of the front side of the body 1. A square cover 14 is rotatably connected to the top of the storage box 13. A handle 15 is fixedly connected to the middle of the top of the square cover 14. A support base 16 is fixedly connected to the bottom of the body 1. A sliding box 20 is fixedly connected to the lower middle of the rear side of the body 1. Multiple hooks 21 are equidistantly slidably connected inside the sliding box 20. Sliding blocks 22 are fixedly connected to the upper and lower ends of the rear side of the body 1. A connecting square plate 19 is fixedly connected to the rear side of the bottom sliding block 22.

[0036] Specifically, the installation of the slot plate 12 facilitates the replacement of the notice board 11, the installation of the storage box 13 facilitates the storage of parts, the installation of the square cover 14 prevents dirt from falling into the storage box 13, the installation of the hook 21 facilitates the hanging of temporary items, and the installation of the sliding block 22 prevents the rack 26 from moving unnecessarily.

[0037] Working principle: The conveyor belt 3 installed in the middle of the inner side of the machine body 1 is responsible for transporting the microchannel aluminum flat tubes to be cooled and dried. The water storage tank 6 fixedly connected to the top of the machine body 1 is filled with water through the water inlet pipe 7 connected to the left side of the top. The second motor 18 is turned on, and the connecting short column 28 fixedly connected to its output end drives the gear 27 fixedly connected to the outside to rotate. The two racks 26 are meshed and driven, which in turn causes the connecting rod 25 fixedly connected to the front side of the rack 26 to drive the connecting hose 23 to move, so that the water sprayed from the nozzle 24 is evenly sprayed on the microchannel aluminum flat tubes on the conveyor belt 3 to complete the gradient cooling process and improve the working efficiency.

[0038] When the first motor 201 is turned on, the rotating short column 202 fixedly connected to its output end rotates, causing the connecting rope 203 fixedly connected to the front and rear ends to wind around. The connecting rope 203 pulls the clamping plate 204 fixedly connected to the left side, causing the bottom of the clamping plate 204 to slide on the top of the conveyor belt 3. The two clamping plates 204 move towards each other to clamp the aluminum flat tube. Due to the installation of the spring 205, it plays a buffering role with the assistance of the telescopic tube 206 and can achieve quick reset. The sliding groove 207 opened in the middle of the left and right ends of the machine body 1 provides guidance for the movement of the clamping plate 204. The conveyor belt 3 begins to transport the clamped aluminum flat tube. Through the above process, unnecessary movement of the aluminum flat tube is avoided.

Although the present 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.
