Enhancement of convective heat transfer in an air-cooled heat exchanger using interdigitated impeller blades

Active heat transfer enhancement in air cooled heat sinks using integrated centrifugal fans

“…Some prior work on the heat transfer in integrated fans similar to the present work was reported by Allison [22,23], who gives two equations for R representing the best design points (equations use SI units): For comparison, in this work, Eq. (29) evaluates to R ¼ 0:668 _ W À0:25 .…”

“…This heat sink, referred to as ''PHUMP'', consists of a loop heat pipe with multiple parallel condensers and integrated, interdigitated centrifugal fans [20][21][22][23]. The fan impellers drive air radially outwards across a multitude of parallel-plate condensers (Fig.…”

“…The linear fit proposed in Eq. (23) has small values of rRMSE (typically less than 10%) for each experiment, meaning that this form of correlation represents each data set with excellent fidelity. Next, the experimental data was collapsed even more by developing an estimator for the correlation coefficients C 1 and C 2 in Eq.…”

“…Next, the experimental data was collapsed even more by developing an estimator for the correlation coefficients C 1 and C 2 in Eq. (23). An average value of C 1 and C 2 could be taken over all experiments, but first the distributions of C 1 and C 2 were examined to determine whether they were normally distributed.…”

Heat Transfer, Fluid Mechanics and Thermodynamics—HEFAT2011

“…In industry, heat transfer, fluid mechanics and thermodynamics are used in environmental studies as engineering sciences to enhance our basic understanding and design capabilities [1] of a broad range of phenomena [2][3][4][5][6][7][8][9][10], equipment [11][12][13], applications [14][15] and systems [16][17] ranging from biological systems [18][19] to common household appliances [20][21], aerospace [22][23], residential and commercial buildings [24][25], mining [26][27], industrial processes [28][29], and electronic devices [30][31]. These disciplines can also be used to conduct techno-economic analyses [32][33][34][35][36][37][38][39] for comparing different types of equipment and systems to allow decisions in terms of capital and running costs in comparison with the cost of financing and impact on the environment [40][41].…”
