Ceramic Heat Sink Thermal Conductivity

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.

Ceramic heat sink thermal conductivity.

A heat sink also commonly spelled heatsink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium often air or a liquid coolant where it is dissipated away from the device thereby allowing regulation of the device s temperature. The value most often quoted is around 180 w mk. 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. Ceramic heat sinks made from al 2 o 3 aluminum oxide or aln aluminum nitride.

Materials of high thermal conductivity are widely used in heat sink applications. It enables the direct and. Excellent high frequency characteristics. Thermal conductivity measures a material s ability to transfer heat.

High chemical resistance and corrosion resistance for long service life. Heat sink and circuit board in one chip on heatsink. Aluminum has a thermal conductivity of 235 watts per kelvin per meter w mk. Exhaust system components with ceramic coatings having a low thermal conductivity reduce heating of nearby sensitive components.

The heat conduction coefficient is high and the stability is good. Heat sink ceramic insulator description. Grease lubricates most efficiently within the listed temperature range. One of the most common metals used in heat sinks is aluminum.

Using ceramic as the material for the heat sink ensures outstanding thermal conductivity and electrical insulation. The closer it is used to a source of heat the greater the cooling advantage it offers. An intriguing example is aluminum nitride ain an increasingly popular ceramic. â anti oxidation â corrosion resistant â waterproof â electrical isolation â 30 lighter than aluminium.

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. The thermal conductivity of a material is a measure of its ability to conduct heat. Melting temperature is the point at which grease will fail and run out of equipment leaving it to run dry. The higher the rating the more heat it transfers.

The thermal conductivity number in this case 235 refers to the metal s ability to conduct heat. 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. Low thermal conductivity great thermal shock.
