Ceramic Heat Sink Thermal Conductivity

In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules.

Ceramic heat sink thermal conductivity.

Ceramic heat sinks made from al 2 o 3 aluminum oxide or aln aluminum nitride. Chip on heat sink on the metalized surface of ceramcool heat sinks makes it possible to achieve an extremely compact design for the entire cooling system. Excellent high frequency characteristics. The heat conduction coefficient is high and the stability is good.

High electrical insulation with high thermal conductivity. Alumina heat sink ceramic insulators are widely used in electrical and electrical fields that require heat conduction heat dissipation insulation high temperature resistance and high voltage breakdown. Melting temperature is the point at which grease will fail and run out of equipment leaving it to run dry. Grease lubricates most efficiently within the listed temperature range.

It enables the direct and. The thermal conductivity of a material is a measure of its ability to conduct heat. The thermal conductivity number in this case 235 refers to the metal s ability to conduct heat. High chemical resistance and corrosion resistance for long service life.

Materials of high thermal conductivity are widely used in heat sink applications. However in reference 1 some interesting data can be found in a graph in which thermal conductivity values from seven manufacturers are displayed as a function of temperature. Heat sink and circuit board in one chip on heatsink. A simplified structure has a direct bond between heat source and heat sink create superior thermal conductivity and electric insulation feature increases components life and stability in the entire assembly.

One of the most common metals used in heat sinks is aluminum. Aluminum has a thermal conductivity of 235 watts per kelvin per meter w mk. The higher the rating the more heat it transfers. The value most often quoted is around 180 w mk.

â anti oxidation â corrosion resistant â waterproof â electrical isolation â 30 lighter than aluminium. An intriguing example is aluminum nitride ain an increasingly popular ceramic. The closer it is used to a source of heat the greater the cooling advantage it offers. The ceramic heat sink ceramcool is an effective combination of circuit board and heat sink for the reliable cooling of thermally sensitive components and circuits.

Exhaust system components with ceramic coatings having a low thermal conductivity reduce heating of nearby sensitive components. Using ceramic as the material for the heat sink ensures outstanding thermal conductivity and electrical insulation. Thermal conductivity measures a material s ability to transfer heat.
