A device that aids in the removal of heat from electronic equipment, and is particularly important when heat is generated in a small area, or when devices such as power transistors, rectifiers and microprocessors are operated. Heat sinks may be added to components, or to complete assemblies. Typically they are made of metal with high thermal conductivity, and the removal of heat may be assisted by built-in fans as well as depending on natural or forced convection.
Facility to provide cooling of PAR and MSR components while "buttoned up" during a nuclear attack. Water for component cooling was re-circulated through an underground storage cavern where its heat was dumped. Photo (B20).
a device, usually made of metal, brought into contact with the hot surface of a component, such as a microprocessor chip, in order to aid the cooling of that componentthrough thermal dissipation by conduction and convection
a device, usually made of metal, brought into contact with the hot surface of a component, such as a microprocessor chip , to help cool that component through thermal dissipation by conduction and convection
A device for dissipating heat; it absorbs heat by conduction from heat producing devices and dissipates heat by means of convection. Heat sinks are common inside fire service thermal imagers to help maintain proper operating temperatures.
A metal mass with fins designed to absorb heat from a 'busy' and therefore hot device, eg the microprocessor in a PC, for which a small fan helps the process, and radiate this heat away safely into the ambient air.
a phenomenon whereby cancerous tissue cools at different rates because of its distance from large blood vessels. A constant supply of warm blood circulating nearby and diffusing heat to the lesion can inhibit the freeze process.
a component generally made of aluminum or a zinc alloy and having fins designed to lower the temperature of an electronic device to which it is attached by dissipating heat into the surrounding air; most modern motherboards require either a heat sink, fan, or both.
A device that radiates or draws heat away from a source, such as a transistors or power diode. Heat sinks are used to increase effective surface area, which increases heat radiating capability, of components. Heat sinks are made of high-thermal-conductivity metals, usually aluminum.
A substance to which heat energy is transferred. A heat sink has a lower level of heat energy (slower moving molecules) than the surrounding material; heat energy travels from one area of high concentration to that of lower concentration
process, or region, in which energy is removed from the atmosphere in the form of heat. Russian translation prepared by Nina A. Zaitseva for the Arctic Climatology Project Arctic Meteorology and Climate Atlas.
A structure that is mechanically attached to a device that generates heat, in order to lower the overall thermal impedance between the point source of the heat within the device and its cooler surroundings.
