Using extruded aluminum heatsinks provides a greater range
of convection solutions needed for high power systems and components. By
forcing raw aluminum through extrusion dies, complex fin profiles have
increased surface area that allows greater heat dissipation. The time and cost
of an equivalent shape using block aluminum is eliminated.
The benefits of extruded aluminum heatsinks include:
• More efficiency
• Lower costs
• Availability of
many sizes and shapes
• Easy
customization for any application
• Weight advantage
over copper
• Mounting tools
and hardware are eliminated
The latest technology is used to test and prototype extruded
aluminum heatsinks to provide the most effective thermal products. Extruded
aluminum heat sinks are designed for forced air cooling and natural convection.
Plating options include chromatic and anodization. Multiple extruded aluminum
heatsinks can be produced. Shapes include tube, solid, semi-hollow, rod, bar,
profile, and hollow. Customers can also specify unique custom shapes.
The compact designs of today require one-piece aluminum heat
sink extrusions. That design prevents premature failure and limits temperature
rise. Heat sink extrusions satisfy a wide range of needs for semiconductor
cooling. Heat sink extrusions are customized to perform optimally for any
application.
Aluminum heat sink extrusions have eliminated
labor-intensive, bonded-fin heat sinks. The overall size has been reduced. The
original heat sink prototype was overdesigned. A thermal analysis that used
maximum operating conditions, environmental constraints and a power component
layout allowed a high-ration extrusion that met the thermal requirements to be
developed.
That is the process used to find solutions to heat sink
extrusion challenges. Often, heat sink prototypes that are too expensive,
too heavy, or too large can be replaced by extruded aluminum heatsinks.
