1.Working principle of dry and wet water tower
Dry-wet water tower is a kind of efficient cooling equipment. It is often called closed water tower because its pipeline is a closed-loop system. The whole system also includes two parts of water. The first part is internal circulation water. We connect the mining machine and the water tank with this part of water. The whole internal circulation pipeline must use pure water, antifreeze or distilled water. Otherwise, the internal pipeline is prone to scaling under high temperature operation, which will be very difficult to clean. The second part is external cooling water. This part of water can use tap water or groundwater. The water tower contains a pump⑧ . The function of this pump is to pump the external cooling water of the water tower from the bottom of the water tank⑦ to the top of the spray system④ Through the ppr pipeline⑨ , and then sprinkle it on the pipe⑤ . The cooling water contacts the pipe to generate hot steam and takes away the heat through the fan ② . The top insulation material③ will effectively condense the water vapor and recover excess water vapor.Then cooled water flows back to the mining machine equipment. During the whole process, the cooling water is kept in the closed system, avoiding evaporation loss, ensuring the efficient use of water resources and long-term stable operation.
2.Dry and wet tower heat dissipation efficiency
The heat dissipation efficiency of dry and wet water tower mainly depends on the external air temperature, humidity, flow rate of cooling medium and design of heat exchanger. Generally speaking, areas with lower wet-bulb temperatures (dry air environments) are more suitable for using water towers. Conversely, areas with higher wet-bulb temperatures have limited heat dissipation effects. The larger the diameter of the pipe, the greater the heat dissipation and the greater the pressure of the spray pump.
3.Water consumption of Dry-wet water towers
The Dry-wet water tower adopts a closed circulation system, so the water inside it will not evaporate and lose, and basically does not require frequent water replenishment, and the water consumption is extremely low. Only during equipment maintenance or extreme environments, the system may have slight water evaporation, and the normal operation of the system can be maintained by appropriate water replenishment. However, there will be a certain consumption of external cooling water, From tens liter to several tons per hour, depending on the size of the water tower and how much heat needs to be dissipatedbut fortunately, these waters only need to use tap water. This heat dissipation method is suitable for most regions and user groups
4.Selection of Dry-wet water tower
Hash Zebra provides a variety of Dry-wet water tower with cooling power ranging from 80kw to 1400kw. For BTC Hyd miners, we have specially designed Dry-wet water tower solutions suitable for mines of different sizes to ensure that customers can choose the most suitable cooling equipment according to the number of equipment, regional climate and other conditions. Each closed water tower undergoes strict quality control to ensure that it can adapt to various extreme climate conditions and has superior transportation convenience. All equipment meets the requirements of international standard container transportation, which is convenient for global delivery and installation.
5.Comparison with dry coolers
Compared with dry coolers, Dry-wet water tower have significant advantages in heat dissipation efficiency and environmental adaptability. Although dry coolers are suitable for extremely arid areas, they rely on air circulation and the heat conduction effect of heat sinks. Under extremely high temperature conditions, the heat dissipation effect may be limited. The Dry-wet water tower, on the other hand, can continuously provide strong cooling capacity for the BTC Hyd miner while consuming some water resources through the internal closed circulation system, ensuring that the miner can operate efficiently under any conditions. In addition, the maintenance cost of the closed water tower is relatively low, which is suitable for long-term use.
6.Conclusion
Hash Zebra’s dry and wet water tower system is an ideal cooling solution for most customers, especially in areas with tight water resources or high environmental requirements, and can provide stable, efficient and energy-saving heat dissipation. Regardless of whether the customer chooses a dry cooler or a closed water tower, we will customize the most appropriate solution based on the actual situation to ensure that the mining equipment can operate stably and for a long time.
