Communication base station inverter cooling chassis

Are data centres and telecommunication base stations energy-saving?

Data centres (DCs) and telecommunication base stations (TBSs) are energy intensive with ∼40% of the energy consumption for cooling. Here, we provide a comprehensive review on recent research on energy-saving technologies for cooling DCs and TBSs, covering free-cooling, liquid-cooling, two-phase cooling and thermal energy storage based cooling.

What are the different phase change cooling technologies in data centres?

Yuan et al. reviewed the technical principles, advantages, and limitations of four major phase change cooling technologies in data centres, namely, stand-alone heat pipe cooling, integrated heat pipe cooling, two-phase immersion cooling and phase change cold energy storage.

How does a DC & TBS cooling system work?

Cooling methods and performance The cooling of DCs and TBSs is mainly achieved using computer room air conditioning (CRAC) units, which consists of a vapour compression refrigeration system for cooling and a cold/hot aisle layout (Fig. 3) (Nada et al., 2016).

What is TES based cooling?

The TES-based cooling can be used in combination with other cooling technologies and has the advantage of reducing the energy consumption of CRACs as well as making full use of natural cool sources through peak shaving. PUE values of DCs and TBSs using these two cooling technologies have the potential for further reduction.

What is a TBS cooling system?

TBSs are communication equipment centres that send, receive and exchange signals in an information transmission network. They have a higher internal heat density than most of general computer rooms and therefore generally need a cooling system with a higher cooling intensity.

Can energy-saving cooling technologies be applied to DCS & TBSS?

Energy-saving cooling technologies, as environmentally friendly and low-cost cooling solution, have been developed low-carbon, energy-efficient and achieving sustainability (Cho et al., 2017). Such cooling technologies could be applied to DCs and TBSs since their servers and racks have similar layouts.
