[0002] With the increasing demands for carbon neutrality, advanced energy utilization, and the development of new materials and processes, there are more and more opportunities to process high-viscosity fluids. However, research on the flow and heat transfer of high-viscosity fluids is relatively weak, making the enhancement of their heat transfer performance, especially their cooling, a key focus. High-viscosity fluids are highly sensitive to temperature; when heated, their viscosity decreases, increasing fluidity and resulting in better heat transfer. Conversely, when cooled, their viscosity increases, leading to laminar flow and less ideal heat transfer. Therefore, we propose a high-viscosity fluid cooler. Utility Model Content

An upper tube sheet 2 is fixedly installed inside the cooling tank 1 near the upper end, and a lower tube sheet 9 is fixedly installed inside the cooling tank 1 near the lower end. A baffle mechanism 3 is fixedly installed on the lower surface of the upper tube sheet 2. A heat exchange structure 4 is fixedly connected between the upper tube sheet 2 and the lower tube sheet 9, and the upper and lower ends of the heat exchange structure 4 pass through the upper tube sheet 2 and the lower tube sheet 9, respectively. A water inlet connector 5 is fixedly connected to the surface of the cooling tank 1 near the upper tube sheet 2, and a water outlet connector 6 is fixedly connected to the surface of the cooling tank 1 near the lower tube sheet 9. A material inlet 7 is connected to the upper end of the cooling tank 1, and a material outlet 8 is connected to the lower end of the cooling tank 1.
[0021] The flow deflector mechanism 3 includes long hangers 301, short hangers 302, a flow deflector center plate 303, and a flow deflector side plate 304. Three long hangers 301 are evenly arranged and installed on the lower surface of the upper tube sheet 2. Short hangers 302 are fixedly installed on both sides of the three long hangers 301 on the lower surface of the upper tube sheet 2. The flow deflector center plate 303 is fixedly installed on the surface of the three long hangers 301. The surfaces of the short hangers 302 and the long hangers 301 closest to the short hangers 302 are fixedly installed... The cooling tank 1 is equipped with baffle side plates 304; multiple baffle middle plates 303 and baffle side plates 304 are provided and are installed inside the cooling tank 1 by alternating long hangers 301 and short hangers 302; the heat exchange structure 4 includes heat exchange tubes 401, expansion tubes 402, contraction tubes 403 and internal inserts 404. Expansion tubes 402 are fixedly installed at the upper and lower ends of the heat exchange tubes 401, and contraction tubes 403 are fixedly connected to the other ends of the expansion tubes 402. The internal component 01 is embedded with an inner insert 404, which is at least 10 meters long and has no splicing welds. The gap between the inner insert and the inner wall of the heat exchange tube is less than 0.1 mm. The surface of the inner insert is polished to achieve a nanometer-level smoothness. The two shrink tubes 403 are respectively recessed into the preset holes of the upper tube sheet 2 and the lower tube sheet 9 at their ends. The other ends of the two shrink tubes 403 are respectively sealed to the upper tube sheet 2 and the lower tube sheet 9 by internal shrink welding.

The ends of the shrink tubes 403 are ground smooth after welding to the upper surface of the upper tube sheet 2 and the lower surface of the lower tube sheet 9. There are two heat exchange structures 4, which connect the upper part of the upper tube sheet 2 and the lower part of the lower tube sheet 9.
[0022] It should be noted that this utility model is a high-viscosity fluid cooler. In use, the cooling material enters the heat exchanger from the material inlet 7, passes through the upper tube sheet 2 and enters the heat exchange tube 401 of the heat exchange structure 4. Under the action of the inner insert 404, the flow direction of the cooling material is continuously changed, breaking the laminar flow state, and finally flows out from the material outlet 8. During this period, the cooling water inlet connector 5 enters the cooling tank 1 and is deflected by the baffle side plate 304 and the baffle middle plate 303. The material exchanges heat with the coolant through the heat exchange tube 401. Under the action of the inner insert 404, the radial temperature difference inside the heat exchange tube is reduced, and the cross-sectional temperature difference inside the heat exchange tube is within 1℃. Compared with the bare tube, the heat transfer coefficient is more than doubled.
