“…Effective energy saving measures such as employing highly efficient air conditioning systems [150,152,153], proper design of the building envelope [154,165,166], indoor airflow optimization [167], as well as the reduction of cooling loads through energy efficient BS electronic equipment and energy management monitoring [168] are some of the solutions that have received more attention in recent years. A study of BS cooling using a two-phase loop-type thermo-siphon system that was integrated inside the wall had been introduced by Nakao et al [166].…”

Abstract:The telecommunication sector plays a significant role in shaping the global economy and the way people share information and knowledge. At present, the telecommunication sector is liable for its energy consumption and the amount of emissions it emits in the environment. In the context of off-grid telecommunication applications, offgrid base stations (BSs) are commonly used due to their ability to provide radio coverage over a wide geographic area. However, in the past, the off-grid BSs usually relied on emission-intensive power supply solutions such as diesel generators. In this review paper, various types of solutions (including, in particular, the sustainable solutions) for powering BSs are discussed. The key aspects in designing an ideal power supply solution are reviewed, and these mainly include the pre-feasibility study and the thermal management of BSs, which comprise heating and cooling of the BS shelter/cabinets and BS electronic equipment and power supply components. The sizing and optimization approaches used to design the BSs' power supply systems as well as the operational and control strategies adopted to manage the power supply systems are also reviewed in this paper.

“…The equipment installed in telecommunication equipment rooms consists of rackmounted units with chips on the PCB (printed circuit board) module. The power density and heat dissipation rate per unit area of the PCB module have increased with technological advancement in the telecommunication hardware [1][2][3]. A proper heat dissipation method from the PCB module of the unit rack of the telecommunication equipment is very important for reliable operation of electronic components.…”

Optimum control of the PCB surface temperature is very important in achieving high performance and operational reliability of telecommunication equipment with high power density and thermal density. In this study, the performance of a liquid cooling unit with MPCM slurries (called as "MPCM cooled unit") was tested and analyzed. In addition, its performance was compared with that of an air cooled unit and a water cooled unit. The maximum surface temperature and the index of uniform temperature distribution (IUTD) were introduced to analyze cooling performance. The surface temperature in the unit rack of telecommunication equipment can be controlled properly by using an MPCM cooled unit instead of an air cooled unit. The maximum surface temperature and IUTD of the MPCM cooled unit at the inlet temperature of 19 o C were lower than those at inlet temperatures of 25 o C and 27 o C due to the increases of heat capacity and heat transfer rate. The heat capacity of the MPCM cooled unit increased significantly with the increase of mass flow rate due to high specific heat of MPCM particles with latent heat transfer rate. The cooling performance of the MPCM cooled unit was superior to that of the water cooled unit.

“…Works with significant connections to multiple categories will be described in their primary category and noted in subsequent categories. A compendium of data center literature was presented by Schmidt and Shaukatullah [8], which compares the cooling, energy efficiency, humidity and contamination requirements between computer and telecommunication equipment rooms and also serves as a historical perspective considering the rapid growth in data center power density.…”

An assessment of the current thermal modeling methodologies for data centers is presented, with focus on the use of computational fluid dynamics and heat transfer as analysis tools, and model validation. Future trends in reduced or compact modeling of data center airflow and heat transfer are presented to serve as an overview of integrating rack-level compact models into full-scale facility level numerical computations. Compact models can be used to efficiently model data centers through varying model fidelity across length scales. Dynamic effects can be included to develop next-generation control schemes to maximize data center energy efficiency.
