Industrial fluids (water, oil, or other liquids) flow in the coil, and the outer wall of the coil is wrapped in sprayed water. The heat of the fluid is transferred through the tube wall, forming saturated hot and humid steam with water and air. The heat is discharged into the atmosphere by the fan, and the moisture is blocked back to the water tank for circulation and spraying, resulting in low consumption. During the circulation of spray water, the water temperature is lowered through PVC heat sinks, forming a cross flow of wind and water with fresh air. The coil mainly relies on sensible heat transfer and other methods. The characteristic of this operating principle is that it may control the formation of scale on the outer wall of the coil.

Due to the air and spray water flowing in the same direction through the coil, the spray water can cover the surface of the coil to a large extent, ensuring that the surface of the coil is completely moist. Compared to the structure with reverse feng shui, it greatly reduces the formation of dry spots and scaling on the coil wall.
 

 

The JBH series side inlet tower features dual inlet air flow and spray water flow in the same direction. The lower part of the cooling coil is equipped with heat dissipation fins, which greatly prevent scaling on the outer wall of the coil and have high cooling efficiency, making it particularly suitable for high-temperature fluid cooling.

1. Added a spray water cooling device in the design to reduce the temperature of the spray water; Make the windward amount and windward area of the cooler uniform, ensuring the heat transfer effect. Increased the efficiency of latent heat of evaporation, resulting in an increase in the cooling capacity of the cooling tower. Effectively alleviated the deposition of scale on the outer wall of the cooling pipe by calcium and magnesium ions in the spray water (due to water temperature ≥ 50 ℃). Reduced the noise of the spray water (the slow descent of the spray water through the PVC radiator reduces the vibration sound).

2. Maintenance free fan: reduces maintenance frequency and labor intensity, improves system reliability. The JBH series closed cooling tower adopts a direct coupled axial flow fan. After the moisture-proof motor is directly connected to the impeller, it is fixed in the air duct as a whole without problems such as belt aging, relaxation, and limited bearing life. It can ensure that the working capacity of the fan is not reduced for a long time, and the work is reliable and the service life is long.

3. Each cooling tower has its own spray system, which has two benefits: first, when it is maintained separately, the spray pump can be stopped separately without affecting the normal operation of other spray pumps; Secondly, the spray pump can be placed in the space at the bottom of the cooling tower, which not only provides shade and rain protection, corrosion prevention, and extends its service life, but also is easy to operate and maintain.

4. The JBH closed cooling tower comes with one control cabinet (including one temperature sensor), which is placed indoors (in the pump room).

4.1 Automatic control of spray pump: The spray pump can automatically control the start or stop of the spray pump based on the temperature sensor's measured water temperature signal, in order to avoid unnecessary energy waste and save energy.

4.2 High temperature alarm: When the circulating water temperature exceeds the set high limit, the control cabinet can provide sound and light alarms to remind manual inspection of the system.
