Experimental and numerical study of pressure drop and heat transfer in a single-phase micro-channel heat sink
The pressure drop and heat transfer characteristics of a single-phase micro-channel heat sink were investigated both experimentally and numerically. The heat sink was fabricated from oxygen-free copper and fitted with a polycarbonate plastic cover plate. The heat sink consisted of an array of rectangular micro-channels 231 lm wide and 713 lm deep. Deionized water was employed as the cooling liq...
متن کاملExperimental Investigation of Low Flow Rate, Low Pressure Drop and Heat Transfer in Micro-Channel
The objective of the current experimental program is to generate data for liquid flow through micro-channels. The channel dimensions are 0.9 mm deep x 0.5 mm width. Rectangular seven micro-channels each of 70 mm long were cut on a stainless steel substrate (100 mm x 100 mm x 10 mm) by Electro Discharge Machining (EDM) technique. Covering the top with another plate formed the channels. The liqui...
متن کاملMeasurement and prediction of pressure drop in two-phase micro-channel heat sinks
This study explores hydrodynamic instability and pressure drop in a water-cooled two-phase micro-channel heat sink containing 21 parallel 231 713 lm micro-channels. Two types of two-phase hydrodynamic instability were identified: severe pressure drop oscillation and mild parallel channel instability. It is shown the severe pressure drop oscillation, which can trigger pre-mature critical heat fl...
متن کاملFluid flow and heat transfer characteristics of low temperature two-phase micro-channel heat sinks – Part 2. Subcooled boiling pressure drop and heat transfer
This second part of a two-part study explores the performance of a new cooling scheme in which the primary working fluid flowing through a micro-channel heat sink is indirectly cooled by a refrigeration cooling system. The objective of this part of study is to explore the pressure drop and heat transfer characteristics of the heat sink. During single-phase cooling, pressure drop decreased with ...
متن کاملNumerical Investigation of Heat Transfer and Pressure Drop in a Corrugated Channel
The influence of variation in rib-height to channel-height ratio (e/H) on the heat transfer and pressure drop characteristics inside a channel with corrugated upper and lower plates was investigated numerically in the present study. The governing equations were solved by using finite volume approximations for a wide range of (0.06 < e/H < 0.26) and Reynolds numbers (5400 < Re < 23000), with a m...
