Custom Extruded Aluminum Heat Sink for LED OEM Aluminium Extrusion
What is a Heat sink?
A heat sink (or heatsink) is an object that absorbs and dissipates
heat. Heat sinks are used in a wide range of applications (such as
LED design) wherever efficient heat dissipation is required. Heat
sinks are made of metal or alloy, which usually includes a
combination of aluminum and copper. Heat sinks may also consist of
one or more flat surfaces to ensure good thermal contact with the
components that need to be cooled, and an array of comb or fin like
protrusions to increase the surface contact with the air, and thus
the rate of heat dissipation.
The performance specification for any heat sink would be thermal
resistance or thermal sensitivity, which is typically expressed in
C° / W as the temperature increase per watt of heat. When comparing
ratings, thermal resistance is a nominal specification. The main
factors that affect thermal resistance or thermal sensitivity
include increased airflow (aerodynamics), forced air or
water-cooling, mounting method, and ambient temperatures.
Frequently, on data sheets for heat sinks, thermal resistance is
presented as a performance curve.
To increase thermal transfer between component and heat sink, a
thermal adhesive (also known as thermal grease) can be added to the
base of the heat sink.
Heatsink surface treatment can be Anodized Aluminum (colored) or
Copper heat sinks can be plated with Silver or Gold.
Applications for Heat sinks:
Typical applications include thermal management of electronics,
often computer central processing unit (CPU) or graphics
processors. You can also find them on transistors, power mosfets,
or on any component that may dissipate high heat. Sometimes you
will find fans used in conjunction with a heat sink to increase
overall airflow. This is known as active heat sink cooling. Heat
sinks are also important in LED design because they provide a path
for heat to dissipate from the LED source to an outside medium.
