Closed cooling tower application principles and advantages

Closed cooling tower application principle:

The closed cooling tower utilizes two-stage cooling means: primary cooling adopts air-cooling to cool the coil of the cooler by air; secondary cooling adopts air-cooling and spraying, and secondary cooling is used when the ambient temperature is relatively high. The air-cooled simultaneous spray system floods the cooler surface and removes heat from the coils as the water evaporates, resulting in a cooling effect.


Closed cooling tower advantages:

1. Circulating cooling medium closed cycle, no impurities to enter, to ensure the purity of the medium;

2. The water circulating water uses soft water, does not scale, does not block the pipeline;

3. small footprint, can be moved, placed according to need;

4. Low energy consumption and easy operation


Closed cooling tower design and main configuration advantages:

1. anti-freeze and anti-fouling type heat exchanger - The perfect closed-type cooling tower adopts improved high-efficiency heat exchanger. The heat exchange coil is optimized on the traditional basis, which can effectively reduce the air side resistance and adapt to the larger amount of spray water. As the tube spacing increases, the number of heat exchange tubes per unit volume increases and the heat transfer area increases. The heat transfer efficiency significantly improves the downward flow of the working fluid inside the tube and the upward flowing of the outside air with the best heat exchange effect. The entire heat exchanger is composed of one or more coil groups surrounded by a steel frame box, which is sturdy and durable. The coil group is made of T2 deoxidized copper tube 0.6mm. It is welded with silver electrodes. All copper tubes are tilted along the flow direction of the working fluid in the tube to facilitate the flow of working fluid. The special low water tank facilitates the recycling of the coil water. And equipped with automatic drainage intake system, to achieve anti-freeze effect, special low-power large-flow spray pump, so that the outer wall of the pipe can be completely wet, to avoid the formation of scale in the wet and dry point joints, special inlet system, can isolate the air particles Dust is combined with calcium and magnesium ions to achieve anti-fouling effect. Well-produced, and must pass the pressure test for 2.5MPa to be allowed to leave the factory.


2. Tower Structure - The robust and closed cooling tower has been carefully designed by our professional designer team and has reached the leading domestic level in performance, appearance and configuration. Preferred partner company!


3. Transmission - Reliable operation fan uses three anti-aluminum material fan, low noise, large air volume, stable operation, balance correction before leaving the factory to ensure its stability.
