Open Cooling Tower
In open circuit cooling towers, there is a direct contact between the water to cool down and the air.
An open cooling tower is a heat exchanger that in order to cool down water makes use of the direct contact with the air. The heat transfer occurs partially thanks to a heat exchange between air and water, but mainly thanks to the evaporation of a small quantity of the water that needs to be cooled. This will allow to cool down to a temperature lower than the ambient temperature.
Principle of operation for open cooling tower
- The water that needs to be cooled will be directed to the upper part of the cooling tower.
- The nozzles distribute water over the tower packing.
- Water will be spread in a thin and even film over the packing thanks to its shape. This will result in a very large contact surface (heat exchange surface).
- The fan blows or extracts (depending on the type of fan) ambient air through the packing. This air will cool the water in 2 different ways. Part of the heat will be removed due to convection (contact between hot water and colder air), but the main cooling part will be because of evaporation.
- The air, which is now saturated with humidity, will be exhausted through the upper part.
- The cooled down water will be gathered in the basin so it can be reused in the production process.
- The drop eliminators above the nozzles make sure that the water drops don't leave the cooling tower.
Components Instruction for open cooling tower
| Open Low-Noise Enclose Type Counter Flow Cooling Tower | |
| CASING AND WATER BASIN | Fiberglass reinforced polyester (FRP) is applied with water-resistance resin and high quality fiberglass mat. With good moisture, high gel,high strength, spray the gel-coat on FRP parts by machine and is thermal formed. |
| FAN & DRIVING SYSTEM | All cooling tower fans with adjustable pitch blades are applied to being balanced, it operates stably and quietly. Material chosen are A.B.S, aluminum alloy for normal standard, F.R.P or stainless steel material available for option.Small capacity cooling tower adopts direct drive low noise fan. Bigger capacity fan equipped with Belt drive speed reducer or Gear box. |
| WATER DISTRIBUTION | Using high coefficient rotating sprinkler head made of plastic or aluminum alloy could reduce the pressure of friction loss, and the water can be distributed evenly to achieve the max thermal cooling performance. |
| FILL PACKING | Used high quality & improved performance PVC with good material, it is high cooling efficiency and anti-corrosive & UL V-0. The surface of infill is corrugated to increase the filling pitch to make sure that infill is clog-free and overcome the problem of water quality. Special material for option if high entering water temperature. |
| FRAME | The framework is made of hot dip galvanized steel (HDGS), to makes the cooling tower in rust-free, durable and long service life. |
