Abstract A review is conducted about the application of the evaporative cooling technology in thermal power plants. Different case studies are considered, namely, evaporative air conditioners, evaporative cooling in direct air-cooled systems, gas turbine inlet cooling, wet cooling towers, and hybrid cooling towers with a crosswind effect. Some effort is provided to describe the advantages related to direct evaporative cooling when it is applied in thermal power plants and illustrate the research gaps, which have not been filled yet. In particular, typical case studies are intentionally used to compare the cooling performances when direct evaporative cooling is implemented in different types… More > Graphic Abstract

Abstract This paper describes the effects of a combination of rib and pulsating flow on heat transfer enhancement in an mm-scale model that simulates the narrow flow passages in cooling devices of downsized electronic equipment. This research aims to develop a novel water cooling device that increases heat transfer performance while inhibiting pumping power. Our recent study has reported that a combination of pulsating flow and rib could enhance heat transfer performance relative to the simple duct. In the present study, to verify the optimal rib height for improving heat transfer by pulsating flow, we evaluated the relationship between heat transfer… More >

Abstract This paper investigates the working fluid with different flow directions on the battery management cooling system with de-ionized water and ferrofluid (0.015%by volume). The pack of batteries with two different coolant directions (Models I, II) used in the present study with sixty Li-ion cylindrical cells (25.2V and 30A) are tested under the trickle method for charged process and constant ampere for the discharged process to consider the battery module temperature distribution and cooling performance. The uniform temperatures of the battery pack significantly affect the long lifecycle and thermal performance. It is found that average temperatures are nearly constant at about… More >

Abstract A lot of researchers have dealt with the heat transfer enhancement of block heat sources mounted on the channel walls by using baffle. On the other hand, the heat generating components are allocated inside the channel or cabinet in many engineering applications. This study aims firstly to investigate the characteristics of conjugate heat transfer of conduction-forced convection in a rectangular channel containing a block heat source module. The module is comprised of a board and five block heat sources mounted discretely on the up surface of the board. Furthermore, efforts are carried out to explore the enhancement of cooling performance… More >
