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
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

Lumped capacitance model — A lumped capacitance model, also called lumped system analysis,[1] reduces a thermal system to a number of discrete “lumps” and assumes that the temperature difference inside each lump is negligible. This approximation is useful to simplify… … Wikipedia
Buck converter — A buck converter is a step down DC to DC converter. Its design is similar to the step up boost converter, and like the boost converter it is a switched mode power supply that uses two switches (a transistor and a diode) and an inductor and a… … Wikipedia
Dynamic insulation — is a form of insulation where cool outside air flowing through the thermal insulation in the envelope of a building will pick up heat from the insulation fibres. Buildings can be designed to exploit this to reduce the transmission heat loss (U… … Wikipedia
