In recent years, data centers have been increasingly developed
into the ones featuring high speed, high density, and large power
consumption. The power consumption of a single cabinet can be
as high as tens of kilowatts, exerting critical air cooling capacity
and efficiency challenges to the data centers. Technologies such as
precision air supply and thermal management system (TMS) can no
longer meet heat dissipation requirements of equipment with large
power capacity.

air cooled. However, with

data centers to deliver either

…… This situation is creating
a need for implementing
liquid cooling solutions.
Huawei liquid cooling solution is a board-level liquid cooling solution
for high-density systems. The solution is green, energy-saving, highly
reliable, highly integrated, and easy to maintain.

Challenges of energy conservation and emission reduction
The energy consumed by traditional air cooling equipment accounts
for more than 40% of the total power consumption in a data center.
High-density scenarios such as high performance computing have
high requirements for energy conservation, emission reduction, and
total cost of ownership (TCO) decrease. The liquid cooling technology,
which outperforms in high efficiency and energy conservation, has
gradually been applied to high-density IT equipment rooms.
