1. What is an impact of excessive fluctuation of inlet temperature on hydro-cooling miners?

It is likely to cause excessive temperature fluctuation or overheating of miners, resulting in unstable operation or failure to work.

2. Are repeated temperature changes in the cooling liquid problematic for the miner?

Repeated temperature changes may not have a significant impact on the miner.

3. What are impacts of excessively high or low inlet flow rate on hydro-cooling miners, respectively?

If the flow rate is too high, a temperature difference of miners may fluctuate excessively, making them unable to work normally. If the flow rate is too low, outlet temperature will be too high, and the miner will also fail to work normally.

4. For M64 series hydro-cooling miner, can I keep the cooling circuit under pressure of 2-3 bar?

Make sure the input pressure of the miner is under 4 bar.

5. For a hydro-cooling miner, the maximum pressure for the inlet side is 400 kPa, what is the pressure leaving the miner?

The diameter of pipes selected for different hydro-cooling systems is different, so the pressure is also different. You can find the system supplier to customize the pressure separately if necessary.

6. Is there a pressure drop in the hydro-cooling system when adjusting different power modes?

No. According to the design of the hydro-cooling system, an expansion tank will be selected and installed in the system based on liquid consumption of the system. The function of the expansion tank is to avoid pressure changes caused by changes in water temperature and to maintain the stable pressure in the system.

7. Can the outlet temperature of a hydro-cooling miner be adjusted?

The outlet temperature can be adjusted, mainly through CDU of the supporting system. The outlet temperature may be affected by flow rate, valve opening, pump speed, etc., but the specific adjustment method can be provided by the corresponding system supplier.

8. What pipe material is recommended for a hydro-cooling system? Why is copper pipe prohibited?

Stainless steel pipe is recommended. Copper pipe is prohibited because it can cause problems such as chemical corrosion and welding slag clogging, leading to damage to hydro-cooling miners.

9. What requirements does a hydro-cooling system have for filtration precision of a filter and a bypass filtration system?

A main road of the hydro-cooling system should be provided with a filter of more than 100 mesh. It is also recommended to configure a 10-micron side filter system to filter tiny suspended substance. If the mesh size of the filter is too low to filter out impurities from large particles in the hydro-cooling system, hydro-cooling plates or quick connectors have the risk of the blockage.

10. How many cycle connection types for a hydro-cooling system?

There are two types of cycle systems in total. Specifically, both cycles include a hydro-cooling cabinet, a hydro-cooling CDU (Cooling Distribution Unit), and a dry cooler. Both have similar components. The biggest difference between the single cycle and the double cycle is that the CDU in the double cycle has a heat exchanger.

The following two figures can simply show necessary components connection in the CDU for the single cycle and the double cycle.

Double Cycle

11. How does a hydro-cooling system prevent leakage when quick connectors are disconnected?

The quick connectors feature a self-sealing mechanism:

When disconnected, both male and female quick connectors will automatically close to prevent leakage.

Ensure that the quick connectors are fully engaged (a clicking sound can be heard) during installation.

12. What other components are needed to run hydro-cooling miners besides a cabinet, and where can I purchase them?

For a complete hydro-cooling system, in addition to the miner and cabinet, the most important thing is its supporting system, which refers to a system for cooling, including pipes, water replenishment tanks, circulating pumps, dry coolers, drainage valves, and so on.

You can choose to purchase our supplier's hydro-cooling system, such as Heat Core hydro-cooling system, and we will provide professionals to build this system for you, so as to help you save time. Of course, you can also build a hydro-cooling system yourself, and we will give you some recommendations in our operation guide.

As for how much power is required for a cabinet, it needs to be analyzed case by case. For example, if you are using the HeatCore cabinet for home use, you can purchase HeatCore H Series, which can accommodate two miners and requires a maximum power of 20Kw. However, if you purchase HeatCore M Series, which can accommodate 10 miners and requires a maximum power of 100Kw.

I can give you an example, the price for the entire set of integrated hydro-cooling cabinet MS100 (HeatCore M Series), dry cooler DC100, and some accessories is 10,845 US dollars (refer to the real-time price for accuracy).

The prices of different types of cabinets also vary. You can refer to the official website of HeatCore https://heatcore.tech/ or contact our sales team for further communication.

13. The operation guide for hydro-cooling miners suggests that the liquid inside the miners should be completely drained during storage and transportation. If the miners are suddenly or temporarily taken out from cabinet and the liquid in the miners is not completely drained, what impact will it have?

If the liquid in the hydro-cooling miners during the storage and transportation is not completely drained, it will cause the following impacts:

If there is no corrosion inhibitor: excessive pressure inside hydro-cooling plates may cause the hydro-cooling plates to bulge, thereby damaging the hydro-cooling plates and hashboards;

If corrosion inhibitor recommended by WhatsMiner is added, there is usually big problem within one week, but the above-mentioned damage risk may still occur beyond this period.
