Copper Foam Heat Sink

The pressure drop crossing the copper foam heat sink increases with the increase in pore density and decrease in porosity.

Copper foam heat sink.

Conventional heat sinks require special appendages such as pins fins or micro channels to increase their surface area. This testing compares a constant heat sink geometry made from copper aluminum and graphite foam. Pastall 100 pcs 8 different sizes heatsink kit with conductive adhesive tape aluminum heat sink cooler and copper heatsink for raspberry pi a b b 2 3 4. From us you can easily purchase copper foam heat absorbing materials at great prices.

Next an application specific heat sink study is presented using computational fluid dynamics cfd software. Free shipping on your first order shipped by amazon. The performance of both an aluminum and copper design was then evaluated using cfd. The copper plate has a number of holes to enhance airflow through the foam lateral flow through a large cross section falls off quickly due to its dense nature.

A thin hard layer of high temperature copper oxide improves the emissivity of the foam boosting the radiant properties of the heat sink and reducing the temperature of the component. For example the thermal resistance of a 40x40x5 mm micro porous copper foam heat sink is 17 4 c w for an applied load of 5w. Copper oxide coated foam heat sinks microporous copper foam coated with a thin hard layer of copper oxide provides outstanding performance as a low profile heat sink in passive cooling environments. The combination of surface area and the thermal conductivity properties of copper enable the height of these heatsinks to be markedly reduced without sacrificing operational performance levels.

4 8 out of 5 stars 31. In this particular experimental analysis copper foam based heat sink is considered for analysis without pcm and with four different pcms i e. Versarien low profile metallic foam heat sinks are designed for use in passive cooling applications where space is at a premium and performance is crucial. Detail comparisons between the results of copper foam heat sinks indicate that the thermal resistance of copper foam heat sink decreases with the decrease in porosity and increase in pore density.

Get it as soon as thu sep 3. The lph00xx series of micro porous copper and foam heatsinks from versarien use homogenously distributed interconnected pores to present a large surface area for enhanced heat dissipation. The underlying microporous copper foam structure of the heat sinks has pore sizes between 300 and 600 microns and a relative density of around 37 providing a much higher surface area than traditional copper foams. As an example of this technology for use in a heatsink a layer of copper foam was bonded to a copper plate using thermal epoxy.
