Ceramic Heat Sink Thermal Conductivity

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.
Ceramic heat sink thermal conductivity. Materials of high thermal conductivity are widely used in heat sink applications. 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. 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. An intriguing example is aluminum nitride ain an increasingly popular ceramic.
Thermal conductivity measures a material s ability to transfer heat. Grease lubricates most efficiently within the listed temperature range. 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. Ceramic heat sinks made from al 2 o 3 aluminum oxide or aln aluminum nitride.
It enables the direct and. The thermal conductivity of a material is a measure of its ability to conduct heat. Aluminum has a thermal conductivity of 235 watts per kelvin per meter w mk. Heat sink ceramic insulator description.
Heat sink and circuit board in one chip on heatsink. High electrical insulation with high thermal conductivity. The heat conduction coefficient is high and the stability is good. 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.
The value most often quoted is around 180 w mk. Low thermal conductivity great thermal shock. Exhaust system components with ceramic coatings having a low thermal conductivity reduce heating of nearby sensitive components. Excellent high frequency characteristics.
Using ceramic as the material for the heat sink ensures outstanding thermal conductivity and electrical insulation. One of the most common metals used in heat sinks is aluminum. 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.
The higher the rating the more heat it transfers. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules. Melting temperature is the point at which grease will fail and run out of equipment leaving it to run dry.
