Aluminum Graphite Heat Sink

It s not as conductive as copper but it s close with a thermal conductivity of 370 w mk.

Aluminum graphite heat sink.

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. However the performance difference increased to 25 30 as the flow rate increased table 3. Schunk aluminium graphite products can be used in various markets including transportation industry and communications technology. This leads to an improvement in the overall reliability of the electronic system.

Yet the literature is void of true comparison of these materials against copper and aluminum. 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. The graphite fins are bonded to the base with thermally conductive epoxy keeping the heat sink.

Find here aluminum heat sink aluminium heat sinks manufacturers suppliers exporters in india. But the real advantage of graphite is its weight it weighs just 70 percent of the weight of aluminum. This behavior is evident in the table below and when comparing the different heat sink materials.

This material is being used today as a fin material in combination with an aluminum or copper base to make hybrid heatsinks. Heat sinks made of aluminium graphite the thermal properties and ability to manufacture components with a wide variety of different geometries make aluminium graphite an outstanding material for conducting heat. The fins of the heat sink are made from graphite while the base is still either copper or aluminum. The graphite heat sink s thermal performance was only 12 lower than aluminum at low flow rates.

Another material that s gaining popularity with heat sink producers is a natural graphite composite material.
