Wet-Dry Coolers With Direct Water Spray System For Bitcoin
Two-phase Liquid Cooling System
Two-phase liquid cooling:
The cooling liquid undergoes a phase change in the process of
circulating heat dissipation. The cooling liquid takes away the
heat from the server and then undergoes a phase change
gasification. The gaseous cooling liquid is condensed by the
condenser and becomes liquid again and returns to the liquid
cooling tank; the cooling liquid can use 3M electronics The boiling
point of the coolant FC-72 and FC-72 is above 50℃. In this case,
the temperature of the water in the condensing coil does not need
to be too low. The use of a dry cooler can meet the heat exchange
requirements and take away the heat. The two-phase liquid cooling
has a high heat transfer efficiency due to the phase change of the
electronic cooling liquid. The disadvantage is that during this
phase change, the electronic fluorinated liquid will escape during
the vaporization process, so there is a certain degree of tightness
of the container. However, it should not be too sealed to prevent
the cooling system from being interrupted and the cylinder
explosion event, so certain safety facilities need to be set up.
Features
1. High efficiency heat exchanger: capacity designs for maximizing
the heat transfer relative to the energy consumption of the fan.
2. Tube and tube coupling design for low pressure drop in the coil
on the media sides(maximum 100KPa at water designing condition).
3. Our thermodynamic and aerodynamic designing software is long
year tested and proved in Germany.
4. Fan: only choose low specific energy consumption fans.
5. Fan nozzle designs for maximum air flow and air throw.
6. Our fans from the world`s leading manufacturer are practically
proved to be reliable in operation and long lasting.
7. Motor: protection class IP 54 and insulation class F.
8. Air separator for each fan.
9. We facilitate you to have a long lasting and low maintainance
operation.
10. Durable material and rigid enclosure with hard gloss powder
coated finish.
11. Protective enclosure for both manifolds and U-bends.
12. Unit design for outdoor installation. 100% leakage tested at
31bar.
Options
A. Coil design refrigerant: water, oil, glycol.
B. Multiple circuits.
C. Sub-cooling circuits.
D. Stainless steel or aluminum casing.
E. Coated aluminum or copper fins.
F. Explosion proof motor.
G. Customized fin spacing.
