Wind power generation equipment, as the core carrier of wind energy conversion, operates in complex outdoor environments for extended periods; its stable and efficient operation directly impacts power generation efficiency and equipment lifespan.

[0003] With the continuous development of wind power technology, the capacity of single units continues to increase, and the heat generated by the equipment also increases. This places higher demands on the heat dissipation efficiency and energy utilization rate of the cooling system. Most existing cooling pipe structures only have a single cooling function and lack effective heat recovery devices, which cannot reasonably recover the heat generated during equipment operation, resulting in low energy utilization rate.

[0004] Therefore, it is necessary to design a wind power cooling pipe with a heat recovery device to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A wind power cooling pipe with a heat recovery device includes a cooling pipe body 1, which includes a main pipe made of 304 stainless steel. This material has excellent corrosion resistance and high temperature resistance, and can adapt to the complex outdoor operating environment of wind power equipment. The diameter of the main pipe ranges from 100-200mm, and the wall thickness is 6-10mm, which can be selected according to the heat dissipation requirements of wind power equipment of different power. The main pipe is connected to a branch pipe, which is welded to the main pipe. The upper end of the main pipe is connected to a bend. Two arc-shaped hollow blocks 2 are provided on the outer side of the main pipe. The arc-shaped hollow blocks 2 are die-cast from aluminum alloy. Aluminum alloy is not only lightweight, but also has good thermal conductivity. Its inner cavity volume is 800-1200ml, and the curvature matches the outer circle of the main pipe. A rectangular plate 7 is provided on the right side of the main pipe. A water tank 9 and two circulating pumps 16 are installed on the rear side of the rectangular plate 7. The water tank 9 is injection molded from polyethylene material, which has good chemical corrosion resistance and insulation. The water tank 9 has a capacity of 10-15L. It has a top-mounted filling port with a sealed cap for easy addition of coolant, and a bottom-mounted drain valve for regular cleaning of impurities. The inlet ends of two circulation pumps 16 are connected to the bottom space of the water tank 9, and the outlet ends of the two circulation pumps 16 are connected to the top space of the corresponding arc-shaped hollow blocks 2 via outlet pipes 10. The bottom spaces of the two arc-shaped hollow blocks 2 are connected to the water tank 9 via return pipes 11. Both outlet pipes 10 and return pipes 11 are flexible hoses made of heat-resistant silicone material with an inner diameter of 12-16mm and a working temperature range of -40℃ to 120℃. These hoses can adapt to different ambient temperature changes and possess good flexibility and aging resistance, allowing them to deform flexibly as the arc-shaped hollow blocks 2 move. Thermally conductive silicone pads are fixedly connected to the inner walls of both arc-shaped hollow blocks 2. The surface of the thermally conductive silicone pads has anti-slip textures to ensure a tight fit with the outer wall of the main pipe, reducing heat loss during transfer.

[0023] The rectangular plate 7 is fixedly connected to a slide rail 8 on its left side. Two connecting blocks 14 are slidably connected to the slide rail 8. The two connecting blocks 14 are fixedly connected to the corresponding arc-shaped hollow blocks 2. The rectangular plate 7 is fixedly connected to two mounting blocks 12 on its left side. Pneumatic rods 13 are fixedly connected to the adjacent sides of the two mounting blocks 12. The telescopic ends of the two pneumatic rods 13 are fixedly connected to the corresponding connecting blocks 14.

[0024] The rectangular plate 7 has a vertical rod 15 fixedly connected to its upper end, and a first arc-shaped block 3 fixedly connected to the upper end of the vertical rod 15. A second arc-shaped block 4 is rotatably connected to the rear side of the first arc-shaped block 3. Both the first arc-shaped block 3 and the second arc-shaped block 4 are made of ductile iron, which has high strength and toughness. A rubber anti-slip pad is provided on the inner side, with an arc consistent with the outer circle of the bend, which increases the friction between the pad and the bend and prevents the device from sliding. A fixing block 5 is fixedly connected to the upper end of both the first arc-shaped block 3 and the second arc-shaped block 4, and a fixing bolt 6 is threaded through both fixing blocks 5.

[0025] A temperature sensor is embedded on the outer wall of the main tube, and a controller is installed on the front side of the rectangular plate 7. The output end of the temperature sensor is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input ends of the two circulating pumps 16.

[0026] The functional principle of this utility model can be explained through the following operation: During the installation stage, the first arc-shaped block 3 and the second arc-shaped block 4 are first fastened to the outer side of the bend at the upper end of the main pipe. By tightening the fixing bolts 6 on the two fixing blocks 5, the overall structure is suspended and fixed on the bend to complete the basic positioning. Then, the pneumatic rod 13 is activated, which pushes the connecting block 14 to slide along the slide rail 8, causing the two arc-shaped hollow blocks 2 to move closer to the main pipe until the heat-conducting silicone pad on the inner side of the arc-shaped hollow block 2 is tightly attached to the outer wall of the main pipe, ensuring the smooth flow of heat.

[0027] When the wind turbine generates heat during operation, the medium flowing inside the main pipe carries the heat. The heat is conducted through the main pipe wall to the thermally conductive silicone pad on the inner side of the arc-shaped hollow block 2, and then transferred to the interior of the arc-shaped hollow block 2. At this time, the temperature sensor monitors the temperature of the outer wall of the main pipe in real time and transmits the temperature signal to the controller. The controller analyzes the temperature data, and when the temperature reaches the set threshold, it automatically starts the circulation pump 16.

[0028] After the circulating pump 16 starts working, it transports the coolant in the water tank 9 to the top space of the arc-shaped hollow block 2 through the outlet pipe 10. During its flow inside the arc-shaped hollow block 2, the coolant absorbs heat transferred from the main pipe. The heated coolant then flows back to the water tank 9 from the bottom space of the arc-shaped hollow block 2 through the return pipe 11, forming a complete cooling cycle. The high-temperature coolant returning to the water tank 9 can be recycled for heat recovery according to actual needs, achieving secondary energy utilization.

[0029] During the cooling process, the controller dynamically adjusts the operating power of the circulating pump 16 based on real-time temperature data fed back by the temperature sensor. When the main pipe temperature is high, the speed of the circulating pump 16 is increased to increase the coolant flow and enhance the cooling effect; when the temperature drops to a reasonable range, the speed of the circulating pump 16 is reduced or it stops operating to avoid energy waste, thereby achieving intelligent and precise cooling control.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
