Upper Heat S Ink Heat Pump Lower Heat Sink
The thermal diffusion factors observed for these systems vary considerably with concentration, and frequently show a change in sign at some concentration. New data on ethanol-toluene mixtures show that the sign and magnitude of the separation of the components in a thermal gradient are also strongly dependent on the mean temperature of the system. These observations, together with earlier ones ...
متن کاملAre sunk costs really sunk?
The problem of relevance of sunk costs in managerial decisions concerning a plant is studied. It is shown that under fairly general assumptions about the rationality of the managers the irrelevance of such costs, frequently claimed by economists and accountants, is weakly founded. An application to a specific problem of use of a machine is studied and the optimal use decision problem solved.
متن کاملHow to Select a Heat Sink
With the increase in heat dissipation from microelectronic devices and the reduction in overall form factors, thermal management bmomes a more and more important element of electronic product design. Both the performance reliability and life expectancy of electronic equipment are inversely related to the component temperature of the equipment. The relationship between the reliability y and the ...
متن کاملAnalysis of Micro Channel Heat Sink Performance
In the present research a numerical investigation has been made to evaluate the results of analytical approach in the analysis of micro channel heat sink (MCHS) which is increasingly used in the cooling of high heat dissipating electronic devices. In this regard the effects of geometrical and flow parameters affecting the absolute thermal resistance of MCHS have been analyzed. The effect of usi...
