Evaporative Condenser&Cooling Tower
1. application features
1.1. power and water saving
Make full use of the temperature difference between the dry and wet spheres in the ambient air, and use evaporation and water absorption to evaporate and absorb. Compared with other water cooling methods, it achieves heat transfer with less cooling water circulation and water consumption.
1.2. save installation space and shorten construction period.
2. structural features
2.1. the reverse flow of air and water, with high velocity, promotes the evaporation of water surface. The cooling water has no secondary drainage and then evaporates. The structure is simple and the space height is low. When the ambient temperature is low in winter, it can work independently with air cooling.
2.2. the heat exchange tube inclines to the end of the coolant flow to make the coolant flow, reduce the flow resistance and improve the heat exchange efficiency.
3. enclosure
The shell can be made of galvanized aluminum sheet, stainless steel sheet and galvanized sheet; Anti corrosion, beautiful; The plate thickness is 1.5-2 (mm).
4. axial flow fan and water pump
The impeller adopts aluminum alloy extruded hollow wing impeller, with light weight, low noise, low strength and high efficiency. The motor is moisture-proof motor with protection grade of IP55 and insulation grade of F.
The pump is a special capacitor pump with large flow, low load, low power and high efficiency. The bearing and shaft seal of the water pump are of well-known brands, and the motor is moisture-proof motor, with protection grade of IP55 and insulation grade of F.
5. Heat exchange coil
Heat exchange tube and internal black metal components are treated by garvanizing process, which has good corrosion resistance. Special design of the heat exchange tube structure, the tube arrangement is more compact, the heat exchange area is large, and the effect is good; The gas-liquid head adopts tube and plate structure, argon arc automatic welding process, the quality of the welding joint is stable and reliable, and the heat exchange tube adopted elliptical welded tube, elliptical tube specification 31.8 × 21.6, SPCC standard material, 304 or 316L stainless steel can also be customized according to customer requirements.
6. sprinkler
The nozzle of the water spraying device adopts a large diameter structure, which can spray water evenly and effectively with large coverage area and is not easy to block.
7. dehydrator
The high efficiency dehydrator is used to return the evaporated water drops to the water tank. The water consumption is small, and the water consumption is less than or equal to 0.001%.
