What is the best material to make fin for more heat transfer coefficient and the best geometric parameter for heat transfer?

2015年9月27日 · The more surface area, the more heat transfer. Ideally you'd use a single-molecule sheet, but that's impractical. Practically, using crushed ice is very simple and very effective. You could also freeze water inside drinking straws or on baking sheets to achieve high area-to-volume ratios.

2022年4月1日 · Four innovative fins with holes and slots in rectangular and circular shapes were investigated experimentally and numerically using the conjugate heat transfer model. The heat transfer coefficient of new plate-fin heat sinks is higher than that of plane fins without slots and holes, according to the results of the CFD model.

2000年3月2日 · Can anyone suggest a good material to make the fins out of or maybe can suggest a preferred shape of the fin for the best transfer. Is this for outdoor use or indoor use? If you expect the fins to hold up to weathering, its best to use a corrosion resistant material (i.e. stainless steel or such)

2023年6月15日 · Two optimization techniques (genetic algorithm and particle swarm) and three geometry representations (binary level set, composite Bézier, and free form deformation) are used to increase the heat transfer and reduce the pressure drop of a heat exchanger fin.

2015年6月1日 · We present optimization results for single rectangular, triangular, and trapezoidal fins. After that, we minimize the mass of an existing heat sink consisting of a base plate and a fin array by optimizing the geometrical variables and component locations on the base plate.

2014年4月1日 · The performance parameters related to the heat transfer and friction factor were found to strongly depend on the cross-sectional rib shapes. The new boot-shaped rib gave the best heat transfer performance with an average friction loss performance, and the reverse pentagonal rib gave the best friction loss performance.

Shape factors for steady heat conduction enable quick and highly simplified calculations of heat transfer rates within bodies having a combination of isothermal and adiabatic boundary conditions. Many shape factors have been tabulated, and most undergraduate heat transfer books cover their derivation and use.

2024年8月28日 · The numerical result shows that circular shape dimples have a greater heat transfer rate compared to both semi-circular and elliptical shape dimples. Further, numerical analysis is carried out for circular dimple shapes by varying different process parameters like dimple depth, diameter, and velocity.

The three principles of heat transfer: convection, conduction and radiation are compared. The full range of sophisticated equipment to simple, portable tool kits are described and the practical...
