Fractal Geometry as an Effective Heat Sink
Strojniški vestnik - Journal of Mechanical Engineering, 2022 "How long is the coast of Britain?" was the question stated by Mandelbrot. Using smaller and smaller rulers the coast length limits to infinity. If this logic is applied to the fractal heat sink geometry, infinite cooling capacity should be obtained using fractals with mathematically infinite surface area.

A novel copper bead heat sink for computer cooling [PDF]
, 2013 The power dissipation of CPU used in desktop computers has been steadily increasing with time. The tendency for a rise in the CPU capacity resulted at present in increasing heat release to 50-100W for desktop PC.

Using of phase change materials to enhance the thermal performance of micro channel heat sink
Engineering Science and Technology, an International Journal, 2018 In this paper using of the phase change materials (PCMs) in a micro-channel heat sink (MCHS) is numerically investigated. The air is first used in heat sink and then four phase change materials (paraffin wax, n-eicosane, p116 and RT41) have been used as ...

Influence of an Electrically Non-Conducting Heat Sink for Power Semiconductors on Radiated Interferences [PDF]
Advances in Radio Science, 2018 Power semiconductors are used in a growing number of applications. Furthermore, faster switching transients and therefore higher switching frequencies can be realised. This leads to higher radiated interferences at higher frequencies.
