Types Of Industrial Fluid Coolers
Counter-flow closed cooling tower;
1. Water is in the filling material of the closed cooling tower, the water is from top to bottom, the gas is from top to bottom, and the two flow into the closed cooling tower in reverse.
2. The countercurrent closed cooling tower has good thermal characteristics and is divided into three refrigeration sections:
(1) The temperature of the indoor space from the rotating nozzle to the top of the filler is relatively high, so the heat can still be transferred to the gas
(2) The heat exchanger section of the filling material water and gas.
(3) The filling material of the closed cooling tower is sent to the water spraying section of the indoor space of the collecting tank, and the cooling circulating water is called the tail effect. Temperatures in northern regions can be lowered by 1-2°C. In general, the filling volume of the counter-flow closed cooling tower is about 20% smaller than that of the cross-flow closed cooling tower. The whole process of heat transfer in the counter-flow tower is more effective, and the cooling efficiency is higher.
3. The water distribution system is not easy to block, the sprinkler filling material is not easy to clean and embrittle, and the moisture flow in the body is small, and the countermeasures against cold and ice are very easy. Several can form a design scheme, and in winter, the fan can be combined to operate alone or completely stop the fan according to the required temperature and water flow.
4. Engineering construction, installation and maintenance are very easy and low-cost. It is common in central air-conditioning and industrial production of large, medium and small refrigeration cooling circulating water.
Cross-flow closed cooling tower;
l. Water is in the filling material in the closed cooling tower, the water flows from top to bottom, and the gas flows into the tower body from the outside of the tower. Commonly found in residential areas with strict noise regulations, it is a refrigeration cycle system tower commonly used in the home appliance industry. Advantages: environmental protection and energy saving, low water release, low air resistance, and a low-speed motor, no water seepage noise and tilting noise, which is conducive to the maintenance of filling materials and water distribution systems.
2. Basically, it can be placed randomly according to the appearance of the project, and a single or several closed cooling towers can be operated according to the required temperature.
3. It must be noted that: the structure needs 40% more heat transfer, and the filling material must have a large volume. The filling material is very easy to embrittle, the drainage outlet is very easy to block, the anti-freezing is not very good, and the moisture flow in the body is large. . The advantages of cross-flow fluid coolers are the disadvantages of counter-flow fluid coolers
Sprayer natural ventilation without filler closed cooling tower;
Select a distinctive nozzle installed at the air inlet at the bottom of the closed cooling tower, there are two methods of sprayer magnetic moment without motor exhaust and tower exhaust system. When the water is sprayed on the nozzle, it causes an internal swirling flow, and a fine mist is sprayed out, so that the mist exists, and the water is sprayed upward to reduce the cooling effect of 2 times. The atomization is uniform, there is no hollow state, the actual cooling effect is stable, the function loss is low, the water drift rate is 0.01%, no filler, low cost, and long service life.
Closed cooling tower;
1. The closed cooling tower is the deformation and development trend of the traditional closed cooling tower. In fact, the water mist of the volatile closed cooling tower is fluid in the tube, and the two do not touch. The water in the storage tank at the bottom of the tower is pumped out by the circulating water pump and sent to the outside of the pipe for uniform spraying. It does not come into contact with the processing liquid boiling water or refrigerant and the gas in the tube, and becomes a closed cooling tower, which improves the actual effect of heat conduction and convection heat transfer according to the sprinkler water.
