  2. Heat sink - Wikipedia

    en.wikipedia.org/wiki/Heat_sink

    The inlet air temperature of the heat sink is therefore higher, which also results in a higher heat-sink base temperature. If there is no air flow around the heat sink, energy cannot be transferred. A heat sink is not a device with the "magical ability to absorb heat like a sponge and send it off to a parallel universe". [2]

  3. Second law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Second_law_of_thermodynamics

    The second law of thermodynamics is a physical law based on universal empirical observation concerning heat and energy interconversions.A simple statement of the law is that heat always flows spontaneously from hotter to colder regions of matter (or 'downhill' in terms of the temperature gradient).

    Temperature vs. heat load diagram of hot stream (H 2 O entering at 20 bar, 473.15 K, and 4 kg/s) and cold stream (R-11 entering at 18 bar, 303.15 K, and 5 kg/s) in a counter-flow heat exchanger. "Pinch" is the point of closest approach between the hot and cold streams in the T vs. H diagram.

  5. Heat pump and refrigeration cycle - Wikipedia

    en.wikipedia.org/wiki/Heat_pump_and...

    A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2] Thus a heat pump may be thought of as a "heater" if the objective is to warm the heat sink (as when warming the inside of a home on a cold day), or a ...

  6. Fin (extended surface) - Wikipedia

    en.wikipedia.org/wiki/Fin_(extended_surface)

    In the study of heat transfer, fins are surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing convection. The amount of conduction , convection , or radiation of an object determines the amount of heat it transfers.

  9. Thermodynamic temperature - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_temperature

    Thermodynamic temperature is a quantity defined in thermodynamics as distinct from kinetic theory or statistical mechanics.. Historically, thermodynamic temperature was defined by Lord Kelvin in terms of a macroscopic relation between thermodynamic work and heat transfer as defined in thermodynamics, but the kelvin was redefined by international agreement in 2019 in terms of phenomena that are ...
