Understanding the physics behind functionality of heatsinks
helps determine the engineering and design elements that govern the quality of
a heatsink. Materials affect the efficiency of heatsinks. Air has low thermal
conductivity. That explains why air cannot be blown past a central processing
unit (CPU) for performance-grade cooling achievement.
Copper makes an excellent heatsink material in many
situations. It has the best potential for conductive heat transfer. Copper
allows heat to transfer quickly. For that reason, applications that require
quick heat transfer utilize the metal. An example of such an application is
found in copper heatsinks.
Searching for copper heatsinks, that utilize copper fins and
copper heat pipe structures is commendable. Copper fins are not a necessity,
but copper heat pipes are highly recommended. Some manufacturers use aesthetic
materials such as nickel plating to cover up copper. Appearance does not always
define the material used in copper heatsinks.
LEDs are used in many applications such as automotive,
industrial, and household lighting. LED applications present thermal challenges
because of cost restrictions, complex environment, dissipation, and small size.
The small size allows LEDs to be clustered together to produce more or brighter
light. Transferring heat from LEDs into heatsinks is extremely important.
LED heatsinks are manufactured to be compatible with specific
LED components. The material used in LED heatsinks is light weight aluminum.
Radial-fin geometry optimizes natural convection. LED heatsinks are easily
mounted with standard hardware. The level of performance and size are matched
to the specific requirements of the purchaser.
