A comparative study of the performance of pin finned heat sinks for cooling electronic components by natural convection

Creator:: Manolescu, Mircea Ion
Abstract:: A study was conducted to determine the heat transfer characteristics of pin finned heat sinks in natural convection. Three pin diameters were studied: 0.238 cm, 0.318 cm and 0.396 cm. The pins were attached to the base in two arrangements, triangular and rectangular, forming a horizontal array. Pin spacing was...

Potential of Genetic Algorithms for Design of Liquid Cooled Heat Sinks Fabricated Using Additive Manufacturing

Creator:: Dokken, Connor B.
Abstract:: The advancement of new manufacturing techniques such as additive manufacturing enable significantly greater freedom of design compared to conventional techniques. Of significant interest is what improvements could be made in the design of cold plates and heat sinks for electronics cooling. Greater design freedom could potentially enable new designs that...

A study of micro-scale, fractal-like branching flow networks for reduced pumping power and improved temperature uniformity

Creator:: Alharbi, Ali Y.
Abstract:: A first generation, one-dimensional predictive model is proposed for designing heat sinks with fractal flow networks. A three-dimensional computational fluid dynamics (CFD) model is analyzed as a means for validating the model and identifying areas for improvement. Two separate CFD models were developed. One was analyzed with conjugate heat transfer...

Experimental study of subcooled water spray cooling using flow symmetric micro-structured surfaces

Creator:: Tulchinsky, Alex M.
Abstract:: Spray impingement cooling has been shown to be a leading candidate for future high heat flux cooling applications. In general, spray cooling curves consist of three heat flux regimes; single-phase, two-phase and critical heat flux (CHF). CHF is considered the design limit for almost all two-phase cooling applications, as a...

A technique for spatially resolved wall temperature measurements in microchannel heat sinks using infrared thermography

Creator:: Krebs, Daniel P.
Abstract:: A non-intrusive measurement technique for direct quantitative thermal visualization of channel wall temperatures in two phase microchannel flows using infrared thermography (IRT) is presented. Specifically, the measurement of top channel wall temperatures in a fractal-like branching microchannel silicon heat sink during flow boiling is demonstrated and thoroughly documented. Obtaining quantitative...

Laminar microchannel cooling of integrated circuits

Creator:: Lienau, Jeffrey Jay
Abstract:: Liquid cooled, laminar microchannel heat sinks were earlier proposed by Tuckerman for cooling high heat generating integrated circuits and high power microwave generation systems using photoconductive switches. A method of computationally analyzing the heat sinks is presented which produces the desired temperature and velocity distributions within the heat sinks. The...

Microscale thermal management utilizing vapor extraction from a fractal-like branching heat sink

Creator:: Apreotesi, Mario A.
Abstract:: It is hypothesized that increases in pressure drop due to vapor generation during boiling in microchannels can be reduced by extraction of vapor at its point of inception. Ultimately, this local vapor extraction decreases the pressure drop required to drive the flow through a fractal-like branching, microchannel flow network within...

Transient conduction with counter mass flow in wood

Creator:: Pfeiffer, Nikolaus, 1960-
Abstract:: This paper deals with the thermal decompositon of wood slabs under fire conditions. The partial differential equation is solved numerically by the use of an implicit finite difference method. Wood is treated as two components, Lignin and Hemicellulose on one side, and Cellulose on the other side. The chemical reactions...

Modeling convective boiling flow with in-situ local vapor extraction

Creator:: Salakij, Saran
Abstract:: The pressure drop of convective boiling flow may be reduced by extracting vapor locally since the entire generated vapor does not have to travel through the entire channel length. In this study, the theoretical model was developed to simulate a convective boiling flow through a fractal-like branching microchannel network with...
