Optimal Finned Heat Sinks
In a multi-board computer system, the volume allocated for heat removal is often a significant fraction of the total system volume. Cooling requirements can thus impact performance, reliability, cost, acoustic noise, and floorspace. This work addresses the volume costs or space requirements for removing heat with optimally designed finned heat sinks. Simple formulas applicable to both gas and l...
متن کاملHeat Transfer from Finned Surfaces
conv hAs (Ts T ) where As is the heat transfer surface area and h is the convection heat transfer coefficient. When the temperatures Ts and T are fixed by design considerations, as is often the case, there are two ways to increase the rate of heat transfer: to increase the convection heat transfer coefficient h or to increase the surface area As. Increasing h may require the installation of a p...
متن کاملCFD Simulation and Experimental Comparison of a Copper Wire Woven Finned Heat Exchanger to an Aluminium Flat Plate Finned Heat Exchanger
The performance of the adsorption cooling system is assessed in terms of the heat transfer coefficients of adsorbent bed heat exchanger. These parameters in-turn determine the specific cooling capacity (SCC) and the coefficient of the performance (COP) of the adsorption cooling system. It was observed that the overall heat transfer coefficients of the heat exchanger have a direct linear relatio...
متن کاملThe Effects of Frost Formation in a Flat Plate Finned-Tube Heat Exchanger
An experimental study on the effects of various factors(fin spacing, fin arrangement, air temperature, air humidity, and air velocity) on the frost growth and thermal performance of a finned-tube heat exchanger has been conducted under the frosting condition. It is found that the thermal performance of a heat exchanger is closely related to the blockage ratio of air flow passage due to the fros...
متن کاملForced Convection Model Of Fan Plate-Finned Tube Type Heat Exchanger At Low Reynolds Numbers
The forced convection experiment of fan plate-finned tube heat exchangers which are mainly used in air conditioners and the forced convection model have been studied for which the heat transfer effect of this type exchangers has not been proposed by a model. All measurements were made when there is no refrigerant flow in the pipe at Reynolds's number of 580. According to the experiment results,...
