Heat transfer — is a discipline of thermal engineering that concerns the exchange of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase change … Wikipedia
Thermal resistance in electronics — Thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time. It is the reciprocal of thermal conductance. The SI units of thermal resistance are kelvins per watt, or the equivalent… … Wikipedia
Heat transfer coefficient — The heat transfer coefficient, in thermodynamics and in mechanical and chemical engineering, is used in calculating the heat transfer, typically by convection or phase change between a fluid and a solid::Delta Q=h cdot A cdot Delta T cdot Delta… … Wikipedia
Thermal management of electronic devices and systems — Heat generated by electronic devices and circuitry must be dissipated to improve reliability and prevent premature failure. Techniques for heat dissipation can include heatsinks and fans for air cooling, and other forms of computer cooling such… … Wikipedia
Heat conduction — or thermal conduction is the spontaneous transfer of thermal energy through matter, from a region of higher temperature to a region of lower temperature, and acts to equalize temperature differences. It is also described as heat energy… … Wikipedia
Thermal transmittance — Thermal transmittance, also known as U value, is the rate of transfer of heat (in watts) through one square metre of a structure divided by the difference in temperature across the structure. It is expressed in watts per square metre per kelvin,… … Wikipedia
Thermal desorption — is an environmental remediation technology that utilizes heat to increase the volatility of contaminants such that they can be removed (separated) from the solid matrix (typically soil, sludge or filter cake). ExplanationThermal desorption is not … Wikipedia
Resistance — may refer to: Physics * Electrical resistance, a measure of the degree to which an object opposes an electric current through it * Friction, the force that opposes (relative) motion ** Drag (physics) ( air resistance ), fluid or gas forces… … Wikipedia
Thermal conduction — In heat transfer, conduction (or heat conduction) is a mode of transfer of energy within and between bodies of matter, due to a temperature gradient. Conduction means collisional and diffusive transfer of kinetic energy of particles of ponderable … Wikipedia
Thermal conductivity — In physics, thermal conductivity, k, is the property of a material that indicates its ability to conduct heat. It appears primarily in Fourier s Law for heat conduction.First, we define heat conduction by the formula::: H=frac{Delta Q}{Delta t}=k … Wikipedia
Thermal contact conductance — In physics, thermal contact conductance is the study of heat conduction between solid bodies in thermal contact. The thermal contact conductance coefficient, hc, is a property indicating the thermal conductivity, or ability to conduct heat,… … Wikipedia
