Thermal performance measurement of heat sinks with confined impinging jet by infrared thermography

Numerical investigation on thermal properties of micro-pin-fin cooler

“…It can be observed that at Fig.10 Temperature distribution on the micro-pin-fin durface a larger inlet diameter, corresponding to a smaller Y D , the average thermal resistance of the heat sink becomes larger. This agrees with the results in [24], where it was found that the thermal resistance reduced obviously as Y D increased. When Y D exceeds 12, the thermal resistance decreases very slowly.…”

Comparison of thermal performances of plate-fin and pin-fin heat sinks subject to an impinging flow

“…They showed that optimized plate-fin heat sinks provide 40% lower thermal resistances compared to optimized pin-fin heat sinks [12]. Li et al [13] compared thermal resistances of several plate-fin and pin-fin heat sinks with various fin heights and Reynolds numbers experimentally using infrared thermography. Contrary to the results presented by Kondo et al, they concluded that the thermal performance of the pin-fin heat sink is superior to that of the plate-fin heat sink.…”

Thermal analysis of a metal foam subject to jet impingement

“…The infrared thermography imaging method is non-intrusive and only can measure the surface temperature of a solid object. Li et al [13] investigated the thermal performance of plate heat sinks with confined impinging jet by an infrared thermal imaging system FLIR (ThermaCAM SC500 camera).…”
