The AFPF heat sinks are subjected to the steady water flow covering the Darcy-Forchheimer regime, and measurements of the flow and heat transfer are performed and compared with the aluminum foam (AF) heat sinks. The results show that the insertion of pin fins into the AF heat sink has ...
Single-phase cryogenic flow and heat transfer through microscale pin fin heat sinks Heat Transfer Eng. (2016) R.S.Prasheret al. Nusselt number and friction factor of staggered arrays of low aspect micropin–fins under cross flow for water as fluid ...
The study covers specifically the heat transfer, friction characteristics of convective heat transfer through a rectangular channel with cylindrical and square (with and without perforation) and diamond cross-section pin-fins attached over a rectangular duralumin flat surface with flow of air. The heat...
parallel fin structures that extend from a heat sink base, providing a large surface area for heat transfer. Pin fins are cylindrical or elongated protrusions that extend from a heat sink base, offering improved air circulation.
Number of pin fins Q : Heat transfer rate (W) Ra : Rayleigh number T : Temperature (°C) V : Electric voltage (V) V a : Air volume in heat sink (m3) V as : Air volume plus heat sink volume in heat sink (m3) α : Thermal diffusivity (m2/s) β : Thermal expans...
A solution in which pin- fins were alternately located with dimples was found to be more efficient than the one composed only of pin-fin columns. Sahiti et al. [15] elaborated the heat transfer and pressure-drop characteristics of a double-pipe pin-fin heat exchanger. Metallic 3D structures...
The work reported in this paper is an attempt to enhance heat transfer in electronic devices with the use of waveform pin-?nned heat sinks. The cooling performance of electronic devices has attracted increased attention owing to the demand of compact siz
Dear CFD experts: I am working on a conjugate heat transfer case: Flow through a heat sink with several vertical fins. Heat source is attached to the
(CPU) or other heat-generating components. Heat sinks work by increasing the surface area available for heat transfer and using fins or other structures to increase the flow of air or other cooling medium over the surface of the heat sink. This helps to keep the device operating at a safe...
The more streamlined drop-shaped pin fins were better at delaying or suppressing separation of the flow passing through them, which decreased the aerodynamic penalty compared to circular pin fins. The heat transfer enhancement of the drop-shaped pin fins was less than that of the circular pin ...
