Fully enclosed water-cooling system
The traditional cooling method relies on water pools and open cooling towers to reduce temperatures. However, this approach has several drawbacks: the circulating water in the pool cannot be effectively controlled, leading to scale buildup inside the equipment’s heat exchangers and water jackets. As a result, the heat transfer efficiency steadily declines, increasing the failure rate of the equipment and ultimately causing production delays. Our company’s fully enclosed water-cooling system ensures that the cooling water remains completely sealed throughout the circulation process. Moreover, the water consumption is only 5% to 6% of that required by conventional water pools. With reduced water usage, we can easily maintain high water quality by using distilled water, thereby significantly minimizing scale formation—or even preventing it altogether—and greatly enhancing the equipment’s service life and operational stability. Additionally, our system transfers heat to the external environment via cooling coils. As the distilled water flows through these coils, a spray pump starts spraying cool water, while a fan begins operating simultaneously. This powerful heat-exchange mechanism keeps the temperature of the internal circulating water within the range specified by the equipment, thus reliably meeting its heat-transfer requirements.
Operating environment 1. The installation of cooling towers should avoid locations with acidic gases, explosive dust, severe soot pollution, and excessive water vapor.
2. When installed next to a building, it should be kept at a sufficient distance from the air intake (0.5–3 m, depending on the model).
3. When installed within a well-type enclosure, be mindful of the risk of hot and humid air flowing back, which could lead to overheating and failure. In special environments, consider installing a ventilation device.Piping issues 1. The piping and butterfly valves should be installed below the operating water level of the cooling tower to prevent overflow and air intake.
2. When considering the placement of equipment, sufficient pump head should be provided, taking into account both the pressure loss due to the head and the pressure loss across the cooling coil.
3. The interface flange for fluid cooling is designed for a pressure rating of 1 MPa; therefore, the piping should be considered for lifting or support.Sprinkler System Maintenance 1. As the closed-circuit cooling tower operates, minerals and other impurities in the water will settle and accumulate in the sump. Therefore, it is essential to regularly monitor water quality and perform periodic drainage and cleaning. This approach helps maintain good water quality and prevent scaling.
2. Requirements for spray water quality: Refer to the “GB50050—95” page on the Design Code for Circulating Cooling Water Treatment. In areas with particularly poor water quality, water purification (softening) treatment should be considered.
3. Supplemental water for spray systems: Evaporation rate ≤ 0.8% of flow rate + drift loss < 0.1% + blowdown rate 0.3% = circulating flow rate ≤ 1.2%.Circulating water The circulating water in a closed cooling tower should meet the water quality requirements of the production process; softened water or purified water, among others, can be used. Closed-circuit cooling tower cooling (very important) 1. When the ambient temperature drops below zero degrees Celsius, heaters can be installed in the spray water tank and within the internal circulation pipes. At the same time, the circulating water inside the tower should maintain a minimum flow rate through the channel coils to prevent freezing.
2. When the equipment is not in use, the circulating water inside the pipes should be drained to prevent freezing and damage to the piping in cold weather.
3. The most effective method is to add antifreeze—either ethylene glycol or propylene glycol—to the closed-loop water-cooling tower.
