Fundamental Studies in Cryogenic Cooling of Power Electronics( )

1 edition published in 1995 in English and held by 0 WorldCat member libraries worldwide

This report is divided into two studies. The first deals with the measurement and modeling of film thickness produced during spray cooling. The experiments were conducted using pressure and air atomizing nozzles. The film thickness increases with decrease in flow rate for pressure atomizing nozzles, although the decrease is small. For air atomizing nozzles, increase in flow rate causes an increase in film thickness while and increase in air velocity causes a decrease in film thickness. Models were derived for both forms of sprays. The second study deals with the effect of operating temperature and cooling technique on power MOSFET characteristics. This numerical study found that the maximum drain current can be more than quadrupled at 78 K as compared to room temperature operation. In comparing spray cooling and immersion cooling, it was found that the maximum drain current possible with spray cooling was more than double that with immersion cooling
Cryo Power and Heat Transfer( )

1 edition published in 1997 in English and held by 0 WorldCat member libraries worldwide

The numerous advantages of operating electronics at the cryogenic temperature have made this research increasingly important Because the foremost problem in electronic cooling is achieving high heat removal capacity within small packages, one focus of this study is to investigate the heat transfer characteristics of various cooling techniques. Pool boiling experiment studies the effects of heater angle orientation and confined spacing on CHF (Critical Heat Flux). The horizontal upward-facing heater gives the highest CHF while the downward facing position causes significant drop in CHF. The study also finds a critical value (s=2.5 mm) for the confined spacing situation. For the heaters in an array, at the vertical orientation, the influence from the lower heater causes a lower CHF of the higher heater. Forced convective boiling in this study can achieve 4 to 5 times higher heat removal rates thin those of pool boiling. A model to describe the heat transfer mechanism near CHF is developed. It is demonstrated that the macrolayer thickness plays the most important role in determining CHF. The effect of flow channel height and heater geometry have been investigated. A practical guideline for the design of a flow boiling system is proposed. A MOSFET (Metal Oxide Semiconductor Field Effect Transistor) will be manufactured, simulated and tested at both room temperature and cryogenic temperature. The simulation results will be compared with the measurements of the real device
Fundamental Studies in Hydrogen Blow-Down and Cryogenic Cooling( )

1 edition published in 1992 in English and held by 0 WorldCat member libraries worldwide

A hydrogen facility designed to conduct experiments relating to blow- down of supercritical hydrogen is described in detail. A theoretical study was conducted to determine the best way of supplying supercritical hydrogen at specified temperature and pressure; the different methods of meeting the required experimental criteria are discussed. The latter part of the study describes experimental arrangements designed and fabricated to study the fluid flow phenomena in free expansion of supercritical/liquid cryogens, and the heat transfer characteristics of cryogens under spray cooling and jet impingement
Fundamental Studies in Blow-Down and Cryogenic Cooling( )

1 edition published in 1993 in English and held by 0 WorldCat member libraries worldwide

Experiments were conducted to study the free expansion (blow-down) behavior of cryogens. Visualization of the phenomena and determination of the final state of LN2 during free expansion were the main purposes of the study. Results presented show the effect of nozzle size, upstream pressure and downstream pressure. The second part of the study details the experiments conducted to study the heat transfer characteristics during spray cooling with LN2. Four different nozzles at various pressures were used to study the variation in spray cooling heat transfer. Effect of nozzle and flow rate on the critical heat flux and overall heat transfer characteristics are presented. Finally an experiment designed to study the LN2 pool boiling heat transfer from discrete sources in a confined space is described.
