What characteristics make a heatsink a good one? There's a
number of factors to consider:Â
• High heatsink surface. It's at the surface of the heatsink
where the thermal transfer takes place. Therefore, heatsinks should
be designed to have a large surface; this goal can be reached by
using a large amount of fine fins, or by increasing the size of the
heatsink itself. Â
• Good aerodynamics. Heatsinks must be designed in a way that
air can easily and quickly float through the cooler, and reach all
cooling fins. Especially heatsinks having a very large amount of
fine fins, with small distances between the fins may not allow good
air flow. A compromise between high surface (many fins with small
gaps between them) and good aerodynamics must be found. This also
depends on the fan the heatsink is used with: A powerful fan can
force air even through a heatsink with lots of fine fins with only
small gaps for air flow - whereas on a passive heatsink, there
should be fewer cooling fins with more space between them.
Therefore, simply adding a fan to a large heatsink designed for
fanless usage doesn't necessarily result in a good cooler.
Â
• Good thermal transfer within the heatsink. Large cooling
fins are pointless if the heat can't reach them, so the heatsink
must be designed to allow good thermal transfer from the heat
source to the fins. Thicker fins have better thermal conductivity;
so again, a compromise between high surface (many thin fins) and
good thermal transfer (thicker fins) must be found. Of course, the
material used has a major influence on thermal transfer within the
heatsink. Sometimes, heat pipes are used to lead the heat from the
heat source to the parts of the fins that are further away from the
heat source. Â
• Perfect flatness of the contact area. The part of the
heatsink that is in contact with the heat source must be perfectly
flat. A flat contact area allows you to use a thinner layer of
thermal compound, which will reduce the thermal resistance between
heatsink and heat source.Â
• Good mounting method. For good thermal transfer, the
pressure between heatsink and heat source must be high. Heatsink
clips must be designed to provide a strong pressure, while still
being reasonably easy to install. Heatsink mountings with
screws/springs are often better than regular clips.
Thermoconductive glue or sticky tape should only be used in
situations where mounting with clips or screws isn't
possible.
