220 V Air Cooler For Building Materials Store
Air cooler is abbreviated as air cooler. It uses air as a coolant and can be used as a cooler or a condenser. The air cooler is mainly composed of tube bundles, brackets and fans. The hot fluid of the air cooler flows in the tube, and the air blows through the tube bundle. Because the amount of ventilation required for heat exchange is large and the wind pressure is not high, axial fans are often used (see fluid conveying machinery).
The type and material of the tube bundle have a great influence on the performance of the air cooler. Because the heat transfer coefficient of the air side is very small, fins are often added outside the tube to increase the heat transfer area and fluid turbulence, and reduce thermal resistance. Most air coolers use radial fins. Air coolers usually use light tubes with an outer diameter of 25mm, low-fin tubes with a fin height of 12.5mm, and high-fin tubes with a fin height of 16mm. The fins are generally made of materials with high thermal conductivity (the most commonly used is aluminum), wound or inlaid on the light pipe. In order to strengthen the heat transfer effect of the air cooler, water can be sprayed in the inlet air for humidification. This not only reduces the air temperature, but also increases the heat transfer coefficient. The use of air coolers can save a lot of industrial water, reduce environmental pollution and reduce infrastructure costs. Especially in water-scarce areas, replacing water-cooling with air-cooling can alleviate the contradiction of water shortage.
