Shanghai Venttech refrigeration equipment Co., Ltd. is a professional dry air cooler for bitcoin immersion cooling system, condenser, evaporator manufacturer in China, which has more 17 years experience in HVAC area.
Dry type air cooler can be used in various cold storages such as architectural or constructional ones. Please refer to the following for general informations. For more details, please contact our sales staff.
By optimizing the refrigerant flow, finned tube material, frosting, wind speed, pipe arrangement, fin spacing and so on. To provide customers the dry cooler with high efficient, compact, light weight, high reliability, energy saving and environmental protection.
The copper tube and aluminum fin of the heat exchanger through the expansion tube process to reduce the contact resistance, increase the pressure of the contact between the aluminum fin and copper tube, so that bulge occur some deformation at the interface, then to reduce the gap, increase the contact area, reduce the contact resistance , enhance heat transfer. Because of the water or medium through the dry cooler, it must be light pipe, which can reduce the resistance of the liquid in the pipeline.
Through thermodynamic calculation, select the number of copper tube suitable for working conditions. In full consideration of gravity and resistance, strictly control the flow rate, reasonable layout, which can make the heat exchanger achieve the best heat exchange performance in the harsh conditions.
The heat exchanger select outer rotor-type fan with low energy consumption, fan motor protection class IP54, insulation class F, each motor with thermal protection, stable operation, long service life.

Dry cooler Auxiliary System:
1. The spray system:
The spray system uses intermittent atomized water to spray on the intake flow to provide an adiabatic cooling effect, reducing the air temperature to near the wet bulb temperature, thereby helping to save a lot of energy and increase work. Improving heat exchange efficiency can increase heat dissipation under the same heat exchange area.
Adding a spray system to the induction cooling system can take away the heat of the circulating water in the data center for most of the year. The spray system increases the heat transfer capacity of the dry cooler, further reducing the operation of mechanical refrigeration.
2. Wet curtain(cooling pad) system:
This type of adiabatic pre-cooling allows return and condensation temperatures below the ambient temperature or a considerably higher unit performance with the same space requirements and improved system efficiency.
