  2. Heat sink - Wikipedia

    en.wikipedia.org/wiki/Heat_sink

    The heat sink thermal resistance model consists of two resistances, namely the resistance in the heat sink base, , and the resistance in the fins, . The heat sink base thermal resistance, , can be written as follows if the source is a uniformly applied the heat sink base. If it is not, then the base resistance is primarily spreading resistance:

  3. Stirling engine - Wikipedia

    en.wikipedia.org/wiki/Stirling_engine

    Not shown: Heat source and heat sinks. In this design the displacer piston is constructed without a purpose-built regenerator. As a consequence of closed-cycle operation, the heat driving a Stirling engine must be transmitted from a heat source to the working fluid by heat exchangers and finally to a heat sink. A Stirling engine system has at ...

  4. Heat spreader - Wikipedia

    en.wikipedia.org/wiki/Heat_spreader

    A heat spreader transfers energy as heat from a hotter source to a colder heat sink or heat exchanger. There are two thermodynamic types, passive and active. The most common sort of passive heat spreader is a plate or block of material having high thermal conductivity, such as copper, aluminum, or diamond. An active heat spreader speeds up heat ...

  5. Passive cooling - Wikipedia

    en.wikipedia.org/wiki/Passive_cooling

    Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process. [7]

  6. Deep water source cooling - Wikipedia

    en.wikipedia.org/wiki/Deep_water_source_cooling

    Deep water source cooling (DWSC) or deep water air cooling is a form of air cooling for process and comfort space cooling which uses a large body of naturally cold water as a heat sink. It uses water at 4 to 10 degrees Celsius drawn from deep areas within lakes, oceans, aquifers or rivers, which is pumped through the one side of a heat exchanger .

    "Kids' bodies produce heat faster than adults and they can't get rid of that heat as quickly," she explains. As a result, children can get sick in extreme heat, and do so faster than many adults ...

  8. Rankine cycle - Wikipedia

    en.wikipedia.org/wiki/Rankine_cycle

    The Rankine cycle is an idealized thermodynamic cycle describing the process by which certain heat engines, such as steam turbines or reciprocating steam engines, allow mechanical work to be extracted from a fluid as it moves between a heat source and heat sink.

  9. Thermal management (electronics) - Wikipedia

    en.wikipedia.org/wiki/Thermal_management...

    Generally, forced convection heat sink thermal performance is improved by increasing the thermal conductivity of the heat sink materials, increasing the surface area (usually by adding extended surfaces, such as fins or foam metal) and by increasing the overall area heat transfer coefficient (usually by increase fluid velocity, such as adding ...
