Aluminum Graphite Heat Sink

Our products are also impressive thanks to their low coefficients of thermal expansion and low density.

Aluminum graphite heat sink.

Get contact details address of companies manufacturing and supplying aluminum heat sink aluminium heat sinks across india. Schunk aluminium graphite products can be used in various markets including transportation industry and communications technology. It s not as conductive as copper but it s close with a thermal conductivity of 370 w mk. Another material that s gaining popularity with heat sink producers is a natural graphite composite material.

The graphite heat sink s thermal performance was only 12 lower than aluminum at low flow rates. Aluminum heat sink 150 x 74 x10 mm 5 9 x 2 91 x 0 39 inch blue heatsinks module cooler fin heat board cooling for amplifier transistor semiconductor devices 4 6 out of 5 stars 6 9 99 9. As a fin material the graphite epoxy composite offers thermal performance significantly better than aluminum and approaching copper but at only 70 and 21 of the weight of aluminum and copper respectively. Find here aluminum heat sink aluminium heat sinks manufacturers suppliers exporters in india.

The fins of the heat sink are made from graphite while the base is still either copper or aluminum. However the performance difference increased to 25 30 as the flow rate increased table 3. Yet the literature is void of true comparison of these materials against copper and aluminum. The graphite fins are bonded to the base with thermally conductive epoxy keeping the heat sink.

This behavior is evident in the table below and when comparing the different heat sink materials. To address the issue of graphite foam as a viable material for heat sinks a series of tests were conducted to compare thermal performance of geometrically identical heat sinks table 1 made of copper aluminum and graphite foam table 2. A wide variety of graphite heat sink options are available to you such as bending cutting and punching. This material is being used today as a fin material in combination with an aluminum or copper base to make hybrid heatsinks.

This leads to an improvement in the overall reliability of the electronic system.
