Bonded fin heat sinks allow a smaller package size
or lower thermal resistance than conventional aluminum extrusions in
forced air applications. We offer signal fin, and corrugated fin options
for our bonded fin heat sinks. Some versions of our corrugated fin stock
have an off set providing greater turbulence resulting in larger heat
transfer. It is normally possible to dissipate two to three times more
heat than conventional aluminum extrusions with our bonded fin designs.
In applications where space and high thermal density is a problem, copper
bonded versions are available. Copper has a thermal conductivity twice
that of aluminum. The fin density and fin height on both can be used
in countless combinations. We can provide you with the best possible
value, based on your unique application.
Extrusions used in a forced air system are the most
common heat sinking method. When compared to a natural convection
system substantially better performance can be realized. It is important
understand too that most "as purchased" extrusion heat sinks
are not sufficiently flat and require machining. Our heat sinks typically
come with a 0.001 per inch flatness and surface finish of 64 micro inches
over the area required. We are constantly working to improve our fin aspect
ratios and fin densities. We continually produce heat sink extrusions that
other manufacturers said "were not possible". For the finest in
extruded air-cooled heat sinks let us assist you with your extrusion design.
We will provide a cost effective solution for your cooling needs.
Liquid cooled heat sinks provide the highest thermal performance
per unit volume and when optimally designed can exhibit a very low thermal
resistance. Liquid heat sinks can be constructed by soldering copper tubing
on to a flat copper plate or by drilling holes in a metal block through
which water may pass. With greater complexity and greater thermal performance
an elaborate serpentine water channel may be milled in a copper or aluminum
block that later is sealed off. While liquid cooling may be considered
undesirable and /or unsatisfactory for many applications it may be the only
viable approach in specific situations. Liquid cooling, in addition to being
compact, keeps noise to a minimum and can increase semiconductor life due to
reduced temperatures. We can also provide chiller units for complete cooling systems.
Typically it is advantageous to design a heat sink
assembly that can reduce waste created by additional handling through
secondary operations at your facility. We will work with you to design
an assembly which can drop right into your product, reducing handling
cost and potential damage. Items integrated into our heat sink assemblies
include, Shielding such as EMI/RFI barrier walls, Hardware like standoffs
and studs for mounting, Chassis and interface sheet metal. Also, we can
provide you with an extensive variety of finishes which include plating,
painting, and silk screening. We want to incorporate as much into the
assemblies as possible so that when you take our assembly to the factory
floor you can immediately interface it to the product for fast shipment
to your customer. We will work with you on mechanical components in order
to reduce your assembly time and inventory cost.
