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.

High electrical insulation with high thermal conductivity. One of the most common metals used in heat sinks is aluminum. Excellent high frequency characteristics. The closer it is used to a source of heat the greater the cooling advantage it offers.

The higher the rating the more heat it transfers. 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. It enables the direct and. Exhaust system components with ceramic coatings having a low thermal conductivity reduce heating of nearby sensitive components.

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. Melting temperature is the point at which grease will fail and run out of equipment leaving it to run dry. 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.

Ceramic heat sinks made from al 2 o 3 aluminum oxide or aln aluminum nitride. 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. 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 heat conduction coefficient is high and the stability is good.

Aluminum has a thermal conductivity of 235 watts per kelvin per meter w mk. Materials of high thermal conductivity are widely used in heat sink applications. The thermal conductivity of a material is a measure of its ability to conduct heat. An intriguing example is aluminum nitride ain an increasingly popular ceramic.

Low thermal conductivity great thermal shock. Grease lubricates most efficiently within the listed temperature range. Using ceramic as the material for the heat sink ensures outstanding thermal conductivity and electrical insulation. High chemical resistance and corrosion resistance for long service life.

The value most often quoted is around 180 w mk. Heat sink ceramic insulator description. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules.
