The care with which we express the dimensions of important parameters makes the difference between conveying useful information or conveying useless or misleading data. Taking the issue of units one more step, the purpose of…read more
Simplified Formula for Estimating Natural Convection Heat Transfer Coefficient on a Flat Plate
August 1st, 2001
Although most of the emphasis today in the electronics cooling community is devoted to extending forced convection cooling capability, many applications still depend upon natural convection cooling. Basically, natural convection cooling combined with radiation is…read more
The Anisotropic Thermal Conductivity of Plastics
August 1st, 2001
The easiest way to tailor thermal conductivity of plastics is to incorporate some highly thermal conductive filler material into the plastic molding compound. Here the filler particles act as heat carriers in the thermally isolating…read more
The Challenge of Operating Computers at Ultra-low Temperatures
August 1st, 2001
Although the potential for low temperature enhancement of CMOS circuit performance has been recognized for some time, circuit scaling (proportionally reducing the size of the circuit) has been the preferred method of achieving higher performance.…read more
The Role of Natural Graphite in Electronics Cooling
August 1st, 2001
Graphite is available as a variety of different material forms, the most useful in the electronics cooling market being pyrolytic graphite, graphite fiber reinforced carbon and polymer matrix composites, graphite foams and, the subject of…read more
Use of Naphthalene Sublimation Technique for Obtaining Accurate Heat Transfer Coefficients in Electronic Cooling Applications
August 1st, 2001
The naphthalene sublimation technique has been demonstrated by a number of investigators to be an excellent method for obtaining heat transfer results [1,2] and a few have applied this technique to applications focused on electronic…read more
Vapor Compression Cooling for High Performance Applications
August 1st, 2001
Vapor compression refrigeration is being adapted to cool computer and telecommunications equipment in a limited number of high performance applications. Vapor compression can lift large heat loads and can heat sink at below ambient temperatures.…read more
