Extruded Heat Sinks

Extruded Heat Sinks

Most Tran-Tec heat sinks are made from extruded aluminum. Tran-Tec maintains a large inventory of heat sink extrusions of various sizes and configurations, many of which are de facto industry standards. Use our Extrusion Search to locate extrusions suitable for your application.Get more news about Aluminum Round Heatsink,you can vist our website!

Even if you can't find an exact match for your needs we can modify extrusions by shortening fins, removing fins to provide component mounting space, cutting to a narrower width or machining features as necessary. Sample quantities of extrusions are available for evaluation. Learn more about how extrusions are made.

If your application requires a shape not in our inventory we can work with you to design a custom extrusion to meet your specific needs. Tran-Tec works with several top aluminum extruders in the U.S. who have years of experience producing in an incredible array of products. For details on available finishes,

Bonded fin heat sinks overcome some of the limitations of extruded aluminum heat sinks by allowing much taller fin heights and denser fin spacing. They also make it possible to use other metals, such as copper, which have greater thermal conductivity but are not as readily extruded as aluminum.

In the basic construction, individual fins are set into a slotted base using high quality industrial grade epoxy glue with powdered aluminum to increase its thermal conductivity. Units with copper bases and copper fins are usually soldered or brazed. Bonded fin can also be economical way to prototype a design for testing that will eventually be extruded.

Tran-Tec has several bases in stock made from aluminum with slots extruded into them. Unlike many other heat sink manufacturers, Tran-Tec does not offer only a limited range of base widths, fin heights and fin spacing. We can also custom slot bases to your specifications.
