| Liquid temperature |
① Working temperature (inlet): 20℃
~50@normal mode 20℃~40℃@high performance
mode; |
| |
② Inlet temperature control accuracy ± 2℃ |
| |
③Storage and transportation temperature: -40~70℃ |
| |
Note: please empty the liquid in the equipment
during storage and transportation. |
| Liquid flow |
①Limited Data：≥10L/min |
| |
②Flow control accuracy ± 10% |
| |
Remarks: 10L/min corresponds to the temperature
difference between inlet and outlet water close to
10℃@normal mode, 14℃ @high performance Mode |
| Liquid pressure |
≤350kpa |
| |
Remarks: when the pressure is more than 350kpa,
the water-cooled plate will be deformed and cause
the risk of coolant leakage. |
| Liquid medium |
First-level deionized water: meet the requirements of the national standard GB/T 6682-2008 first-level deionized water |
| |
Notice:
1)If the water conductivity is ≥100us/cm, the medium must be replaced;
The water conductivity is less than 5us/cm when the system is running for the first time. |
| Liquid PH |
Control range: 6~8 |
| Liquid medium circulation |
①Anti-rust and anti-corrosion of pipeline; |
| system(Machine side) |
②The particle diameter of the liquid medium is ≤53
microns, that is, the circulation system isequipped with a 270 mesh filter; |
| |
③Before connecting the cabinet to the heat dissipation system, clean and filter the system pipeline with |
| |
deionized water to remove dust, welding slag and
other impurities; |
| |
④The temperature resistance of system components is
above 85℃; |
| |
⑤The circulatory system is recommended to be equipped with a UV lamp sterilization device to prevent the liquid from breeding bacteria and attenuate the heat dissipation capacity of the system; |
| |
⑥The system is equipped with a 4bar safety relief valve; |
| |
⑦The system is equipped with a constant pressure
expansion tank. |
| |
Note: when the temperature of the coolant rises after the miner is turned on the pressure will rise. |
| Humidity |
①Working humidity: 5%RH~85%RH (non-condensing) |
| |
②Storage humidity: 5%RH~95%RH (non-condensing) |
| |
③Long-term storage humidity: 30%RH~69%RH
(no condensation) |
| |
Remarks: The above liquid temperature and flow parameters are based on deionized water as the liquid medium. If the liquid medium uses antifreeze, the liquid temperature and flow parameters need to be calculated separately. Table 2 shows an example of 30% glycol antifreeze temperature and flow parameters. |
