Air - water heat exchanger of cooling unit

Air - water Heat Exchanger of cooling unit

Product introduction

Air cooler, referred to as "air cooler", also called fin fan, commonly used to replace the water cooled shell - tube heat exchanger cooling medium. It is a device for cooling or condensing the high temperature process fluid inside the tube by sweeping the finned tube with ambient air as the cooling medium. Air cooler is mainly used in petroleum, chemical, metallurgy and other air cooler supporting use, with large air volume, high efficiency, low vibration, low noise, easy maintenance and other advantages. The air cooler is mainly composed of tube bundle, support and fan. The type and material of tube bundle have great influence on the performance of air cooler. Because the heat transfer coefficient of the air side is very small, it is often added in the tube fin, in order to increase the heat transfer area and fluid turbulence, reduce the thermal resistance. Most air coolers use radial fins. Industrial Air Cooler,Greenhouse Air Cooler,Cooling System Evaporative Air Cooler Air coolers usually use light tubes with an outside diameter of 25mm, low fin tubes with a fin height of 12.5mm and high fin tubes with a fin height of 16mm. Fins are generally made of a material with high thermal conductivity (most commonly aluminum) and are wound or mounted onto the light tube.

Note:

1. The medium, temperature and pressure in the pipe should meet the design conditions, and overpressure and overtemperature operation is strictly prohibited;

2, the pipe pressure, temperature, should be slowly step by step, so as not to damage the equipment due to impact heat;

3, the air cooler normal operation, should first open the fan, and then to the tube bundle into the medium, stop the operation, should first stop to the tube bundle into the medium, then stop the fan;

4, the negative pressure operation of the air cooler boot, should first open the air extractor, tube to reach the specified vacuum degree and then start the fan, and then through the tube medium, shut down, according to the opposite procedure, winter operation, open the air extractor, to reach the specified vacuum degree, first through the tube medium, then start the fan, so as not to freeze the tube can not run;

5. When stopping, low pressure steam should be used to purge and clean the condensate to avoid freezing and corrosion.
