Staggered aluminum circle Pattern Graduated Fin Spacing

Optimization Of Micro Pin-Fin Heat Sink With Staggered

The best thermal performance enhancement of 106% was obtained by using staggered triangular fins with larger fin height of 0.75 mm, smaller fin width of 0.5 mm and spacing double the fin width

CF Series Engineering Data - SPX Cooling

Tubes are 3/4\" or 1\" O.D., staggered in the direction of airflow. \"Turbo-Spacers\" on 3/4\" O.D. coils are located between tubes to provide nominal fin spacing and improve fin efficiency by turbulating the airflow. 1\" O.D. coil units are spaced on the tube to offer cleanability and unequaled fin spacing patterns to match application

Louvered Heat Exchanger Fin Stock - Nordyne,

The wind tunnel tests of a scale model of the FIG. 2 construction are interpreted as indicating that, at the relatively wide fin spacing of 121/2 fins per inch (increased from the prior 14 fin/inch spacing) there will be an approximate 5% improvement in the \"S.E.E.R.\" rating as compared to the fins made according to my U.S. Pat.

Optimization Of Short Micro Pin Fins In Minichannels

Jul 01, 2012  The third investigation was conducted in efforts to optimize the fin dimensions and spacing using the square pin fin geometry. Because the fin width, w f, fin spacing, S t, S L, and number of fins, N, are all dependent on one another, the ratio of fin width times the number of fins in the row, N x, to the channel width, N x w f / w c, is kept constant at a value of

Parametric Study On The Combined Thermal And Hydraulic

Nov 01, 2010  Earlier in 2005 Peles et al. studied the performance of micro pin-fin heat sinks by studying the pressure drop and heat transfer in the micro heat sink by varying the geometry spacing and arrangement of the pin-fins. All the structures were made in silicon wafer and the geometries selected were circle, hydrofoil, cone, and
