Ceramic Heat Sink Thermal Conductivity

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

Ceramic heat sink thermal conductivity.

Melting temperature is the point at which grease will fail and run out of equipment leaving it to run dry. 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. 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. Ceramic heat sinks made from al 2 o 3 aluminum oxide or aln aluminum nitride.

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. â anti oxidation â corrosion resistant â waterproof â electrical isolation â 30 lighter than aluminium. Low thermal conductivity great thermal shock. Grease lubricates most efficiently within the listed temperature range.

Materials of high thermal conductivity are widely used in heat sink applications. 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. Heat sink ceramic insulator description. The closer it is used to a source of heat the greater the cooling advantage it offers.

Using ceramic as the material for the heat sink ensures outstanding thermal conductivity and electrical insulation. Aluminum has a thermal conductivity of 235 watts per kelvin per meter w mk. Heat sink and circuit board in one chip on heatsink. High chemical resistance and corrosion resistance for long service life.

One of the most common metals used in heat sinks is aluminum. Thermal conductivity measures a material s ability to transfer heat. Exhaust system components with ceramic coatings having a low thermal conductivity reduce heating of nearby sensitive components. The thermal conductivity of a material is a measure of its ability to conduct heat.

It enables the direct and. High electrical insulation with high thermal conductivity. In computers heat sinks are used to cool cpus gpus and some chipsets and ram modules. The higher the rating the more heat it transfers.

An intriguing example is aluminum nitride ain an increasingly popular ceramic. Excellent high frequency characteristics. The heat conduction coefficient is high and the stability is good.
