Computations of liquid immersion cooling for a protruding heat source in a cubical enclosure

International Journal of Heat and Mass Transfer, 1993
Abstract Three-dimensional natural convection flow and heat transfer were studied numerically for a heated, protruding substrate-mounted chip or package in a cubic enclosure filled with a dielectric liquid. The governing steady-state equations for the natural convection within the liquid and the conjugate conduction within the element and the ...

A Simple Thermal Model for Mixed Convection From Protruding Heat Sources

Heat Transfer Engineering, 2014
This paper reports the results of numerical and experimental investigations of conjugate mixed convection from a vertical channel with sets of protruding heat sources. The goal of this study is to investigate the possibility of obtaining reasonably accurate results with a simpler or compact thermal model that replaces a set of protruding heat sources ...

The Aspect Ratio Effect on Natural Convection in an Enclosure With Protruding Heat Sources

Journal of Heat Transfer, 1991
The aspect ratio effect on natural convection heat transfer in a rectangular enclosure with protruding heat sources has been experimentally investigated. Five protruding heaters were mounted with uniform vertical spacing on one vertical wall. The vertical wall opposite to the wall on which heated sections were mounted was movable so that the enclosure ...

Heat transfer enhancement from protruding heat sources using perforated zone between the heat sources

Applied Thermal Engineering, 2009
Abstract This study is to experimentally investigate the heat transfer enhancement by perforation in air cooling of two in-line rectangular heat sources module. Two separation distances between the heat sources were investigated at s/L = 0.5 and 1.0. The area between the heat sources in both cases were perforated in aligned arrangement such that the ...

Experimental and Numerical Investigation of Mixed-Convection Heat Transfer from Protruding Heat Sources in an Enclosure

Experimental Heat Transfer, 2012
Heat transfer from a 5-by-4 array of protruding heat sources in the bottom wall of an adiabatic enclosure is investigated experimentally and numerically. The enclosure has a fixed inlet and different outlets. Flow velocity and applied heat fluxes are varied. Steady-state temperatures of the heat sources, air inlet and outlet temperatures, and enclosure

Mixed convection air cooling of protruding heat sources mounted in a horizontal channel

International Communications in Heat and Mass Transfer, 2009
Abstract A numerical study of laminar mixed-convection heat transfer to air from two identical protruding heat sources, which simulate electronic components, located in a two-dimensional horizontal channel, is presented in this paper. The finite volume method and the SIMPLER algorithm are used to solve the conservation equations of mass, momentum ...
