If battery packs for electric vehicles (EVs) and hybrid electric vehicles (HEVs) are to operate effectively in all climates, thermal management of the packs is essential. In this paper, we will review a systematic approach for designing and evaluating battery pack thermal management systems. A thermal management system using air as the heat transfer medium is less complicated than a system usin...

Data centers are seeking more efficient cooling techniques to reduce their operating expenses, because cooling can account for 30-40% of the power consumption of a data center. Recently, liquid cooling has emerged as a promising alternative to traditional air cooling, because it can help eliminate undesired air recirculation. Another emerging technology is free air cooling, which saves chiller ...

The increased circuit density on today’s computer chips is reaching the heat dissipation limits for air-cooling technology. The direct liquid cooling of chips is being considered as a viable alternative. This paper reviews liquid cooling with internal flow channels in terms of technological options and challenges. The possibilities presented herein indicate a fourto ten-fold increase in heat fl...

this article presents a transient model of a solar adsorption cooling system. a computer program has been developed to simulate the operation of a two bed silica gel- water adsorption cooling system as well as flat plate collectors and the hot water storage tank. this program is then utilized to simulate the performance of a sample solar adsorption cooling system used for cooling a set of rooms...

Wind power is experiencing steady growth, and wind turbine technologies are continually developing. Currently, power ratings of up to 20 MW are being considered for future wind farms. Offshore applications, which call for the largest and most powerful wind turbines, demand a higher standard of reliability and maintainability. Because they offer better overall efficiencies and higher reliability...
