Water-cooled energy storage and heat dissipation

What is a server water cooled system?

Fig. 1 (a) shows the system flowchart. A server water-cooled system, including a cabinet, fin-type water-cooled heat sinks, two pumps, plate heat exchanger, and cooling tower, with a total load of 4.8 kW. The server cabinet contained 12 chips, with a thermal power of 400 W for each chip.

How does a server cooling water transfer heat?

The heat carried by the server cooling water is released to the cooling tower water in the heat exchanger first, and finally to the atmospheric environment. Therefore, more attention should be paid to the cooling-tower water mass flow rate and atmospheric conditions.

Can water-cooled heat sinks reduce energy consumption of data center?

In order to reduce the energy consumption of data center caused by cooling system, research on the water-cooled heat sinks used to cool chips has become increasingly important with the steep increase in the heat flux density of data centers.

Why is expanding the heat dissipation area important?

Because of the limited space inside the cabinet, expanding the heat dissipation area is the optimization direction of the water-cooled plate with a balanced performance between pressure drop, maximum temperature, and temperature uniformity.

Can a liquid cooling data center drive adsorption refrigeration cycle?

Waste heat from a liquid cooling data center was utilized to drive an adsorption refrigeration cycle in Ref. , and the generated refrigeration capacity of the ARC was further used for air cooling. It was found that for a 350 kW water cooling system and a 50 kW air cooling system, the discounted payback period (DPB) was as low as 285 days.

How does humidity affect server water cooled systems?

From this, the optimal cooling water flow rates, optimal server inlet temperature, and minimum total energy consumption of the server water-cooled system showed a nearly linear increase with increasing atmospheric relative humidity for both A- and B-types, which was determined by the cooling tower characteristics.
