Description

Technical Field

[0001] This utility model relates to the field of air coolers, specifically a swirl-enhanced air duct type air cooler. Background Technology

[0002] An air cooler is a device that uses air as a cooling medium to cool fluids. It mainly consists of tube bundles, fans, and a frame. During operation, the fluid to be cooled flows inside the tube bundle, while the fan forces air to flow horizontally or vertically across the outer surface of the tube bundle. Through heat exchange between the air and the fluid inside the tube bundle, the fluid temperature is lowered, achieving the cooling purpose.

[0003] Air coolers are widely used in industrial production and equipment operation as crucial cooling devices. Traditional air coolers have limitations in structural design and airflow guidance, resulting in cooling efficiencies that cannot meet the ever-increasing demands. Furthermore, achieving high cooling performance often requires high-power fans, which not only wastes energy but also generates significant noise, negatively impacting the working environment and equipment stability. Therefore, developing new air coolers that improve cooling efficiency is of significant practical importance. Utility Model Content

[0019] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0020] Please see Figures 1 to 5 This utility model provides a swirl-enhanced air duct type air cooler, including a front cover plate 1, a rear cover plate 3 is clamped and fixed to the inner wall of the rear end of the front cover plate 1, an air cooler radiator 2 is fixed inside the front cover plate 1, the front cover plate 1 includes a cover plate body 11, a circular opening is opened at the front end of the cover plate body 11, a support member 12 is fixed inside the circular opening, and a main flow vane 13 is installed at the rear end of the support member 12.

[0021] Improved cooling efficiency: Through the spiral blade design of the main flow vane 13 and the cooperation of the auxiliary flow guide vane 15, the airflow entering the air cooler forms a stable vortex, enhancing the contact and heat exchange effect between the airflow and the air-cooled radiator 2. Under the same power, the cooling efficiency is greatly improved, significantly enhancing the performance of the air cooler and better meeting the cooling needs of equipment in industrial production; Reduced fan energy consumption: Due to the improved cooling efficiency, the fan does not need to operate at a higher power to achieve the same cooling effect, thereby reducing the fan's energy consumption and achieving energy saving. This not only helps reduce the company's operating costs but also meets the requirements of energy conservation and emission reduction in today's society; Achieved energy saving and noise reduction: The reduction in fan power directly leads to a reduction in noise, creating a quieter and more comfortable working environment for employees. At the same time, the energy-saving and noise-reducing characteristics also give this vortex-enhanced air duct air cooler a greater advantage in environmental protection, which is conducive to promoting the development of green industry.

[0022] A fixed shaft 14 is fixedly connected to the inner wall of the cover plate body 11. There are four sets of fixed shafts 14, and auxiliary guide vanes 15 are rotatably connected to the ends of the four sets of fixed shafts 14.

[0023] The main flow blade 13 includes a fixing nut 131, and a blade shaft 132 is rotatably connected to the rear end of the fixing nut 131. The blade shaft 132 is a cylindrical design that is narrow at the front and wide at the back. Blades 133 are fixedly connected to the surface of the blade shaft 132. Several sets of blades 133 are arranged in a spiral on the surface of the blade shaft 132.

[0024] The air-cooled radiator 2 includes a limiting plate 21, which has two sets. An inlet pipe 22 is fixedly connected between the two sets of limiting plates 21. An outlet pipe 24 is fixedly connected to one end of the inlet pipe 22. Several sets of heat dissipation fins 23 are sleeved on the surface of the inlet pipe 22.

[0025] A flange is fixed to the front end of the front cover plate 1, and an external fan is fixed to the front end of the flange. A through air vent is opened in the center of the surface of the rear cover plate 3, and the air vent corresponds to the air-cooled radiator 2.

[0026] The cover plate body 11 has square openings on both sides. The two sets of square openings correspond to the two sets of limiting plates 21. The rear cover plate 3 is clamped behind the cover plate body 11 to limit and fix the rear of the air-cooled radiator 2.

[0027] When the air cooler starts working, the fan is installed at the flange of the front cover plate 1 and starts. The fan rotates at high speed, generating a strong suction force, which causes the surrounding air to quickly converge towards the fan and enter the air cooler at high speed through the fan hole of the front cover plate 1.

[0028] At this point, the main flow blade 13 begins to function. Due to the cylindrical design of the blade shaft 132, which is narrow at the front and wide at the back, and the spiral arrangement of the blades 133, when the airflow impacts the main flow blade 13, the airflow will impact the blades 133 and rotate on the surface of the blade shaft 132. At this time, the airflow flows along the spiral surface of the blades 133. This flow mode causes the airflow to form a rotational motion around the blade shaft 132, which gradually develops into a stable vortex. The formation of the vortex changes the flow direction and velocity distribution of the airflow, so that the airflow no longer simply passes through the air cooler in a straight line, but moves in a complex trajectory of spiraling up or down, which greatly increases the flow path length of the airflow inside the air cooler.

[0029] Meanwhile, the auxiliary guide vanes 15 also work in coordination. The four sets of auxiliary guide vanes 15 are rotatably connected to the inner wall of the rear end of the cover plate body 11 through the fixed shaft 14. They can rotate and adjust according to the actual airflow. When the vortex formed by the main flow vane 13 passes through the auxiliary guide vane 15, the auxiliary guide vane 15 will rotate synchronously to further correct and optimize the vortex. For example, if the airflow distribution is uneven in some areas, the auxiliary guide vane 15 in the area with stronger wind will rotate to guide the airflow to the area with weaker airflow, and drive the auxiliary guide vane 15 in the area with weaker wind to rotate, so that the airflow distribution in the entire duct is more uniform. This uniform airflow distribution can ensure that all parts of the air-cooled radiator 2 can fully contact the airflow and avoid local overheating or insufficient cooling.

[0030] The swirling airflow continues forward, making full contact with the heat dissipation fins 23 on the surface of the air-cooled radiator 2. The heat dissipation fins 23 have a large surface area, enabling them to quickly absorb heat from the fluid in the inlet pipe 22 and transfer it to the airflow in contact with them. Because the airflow is in a swirling state, its contact with the heat dissipation fins 23 is more thorough and frequent, more effectively removing heat from the fins 23. Specifically, the swirling airflow continuously impacts various surfaces of the heat dissipation fins 23 during its flow, creating a strong convective heat transfer effect.

[0031] During the heat exchange process, fluid (such as hot water or hot oil) is injected into the inlet pipe 22 in advance. Then, the inlet pipe 22 and the outlet pipe 24 are connected by a connecting pipe to form a circulation pipe. The fluid continuously carries the heat generated by the equipment into the air cooler, while the heat dissipation fins 23 continuously transfer the heat to the airflow. After sufficient heat exchange, the airflow temperature rises and is then discharged from the air vent of the rear cover plate 3, completing the entire cooling cycle. At the same time, the fluid in the inlet pipe 22, whose temperature has decreased, flows back to the equipment through the outlet pipe 24 to continue absorbing the heat generated by the equipment. This cycle repeats continuously to achieve continuous cooling of the equipment.

[0032] During this process, due to the unique air duct design and airflow guiding structure, the heat exchange efficiency between the airflow and the air-cooled radiator is greatly improved. Under the same fan power, more heat can be removed, thereby achieving improved cooling efficiency, reduced fan energy consumption, and energy saving and noise reduction effects under the same power.
