  2. Thermosiphon - Wikipedia

    en.wikipedia.org/wiki/Thermosiphon

    Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used). A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump.

  3. Radiator (engine cooling) - Wikipedia

    en.wikipedia.org/wiki/Radiator_(engine_cooling)

    In effect, the evaporative version is operating between 80 °C and 560 °C, a 480 °C effective temperature difference. Such a system can be effective even with much smaller amounts of water. The downside to the evaporative cooling system is the area of the condensers required to cool the steam back below the boiling point. As steam is much ...

  4. Ford Model T engine - Wikipedia

    en.wikipedia.org/wiki/Ford_Model_T_engine

    Overview of the thermosyphon cooling system of the Ford Model T engine. [7] The T engine's cooling system reflected the T's simplicity design theme. The first few hundred Model Ts had a water pump, but it was eliminated early in production. Instead, Ford opted for a cheaper and more reliable thermosyphon system. Thermosyphon was a common engine ...

  5. Thermic siphon - Wikipedia

    en.wikipedia.org/wiki/Thermic_siphon

    The concept of a self-circulating thermic syphon began with stationary boilers and relatively simple Galloway tubes.They reached their peak in steam locomotive boilers, where the complexity of a syphon was justified by the need for a compact and lightweight means of increasing boiler capacity.

  6. Silk 700S - Wikipedia

    en.wikipedia.org/wiki/Silk_700S

    The engine had no water pump, using instead a thermo-syphon cooling system. Coolant in the cylinder jackets absorbed engine heat and rose convectively via a rubber tube to the radiator. The cooled liquid was denser and returned through another tube to the base of the cylinders.

  7. Reboiler - Wikipedia

    en.wikipedia.org/wiki/Reboiler

    Thermosyphon reboilers (Image 2) do not require pumping of the column bottoms liquid into the reboiler. Natural circulation is obtained by using the density difference between the reboiler inlet column bottoms liquid and the reboiler outlet liquid-vapor mixture to provide sufficient liquid head to deliver the tower bottoms into the reboiler.

  8. Barra system - Wikipedia

    en.wikipedia.org/wiki/Barra_system

    The Barra system is a passive solar building technology developed by Horazio Barra in Italy.It uses a collector wall to capture solar radiation in the form of heat. It also uses the thermosiphon effect to distribute the warmed air through channels incorporated into the reinforced concrete floors, warming the floors and hence the building.

  9. Dilution refrigerator - Wikipedia

    en.wikipedia.org/wiki/Dilution_refrigerator

    A 3 He/ 4 He dilution refrigerator is a cryogenic device that provides continuous cooling to temperatures as low as 2 mK, with no moving parts in the low-temperature region. [ 1 ] [ 2 ] The cooling power is provided by the heat of mixing of the helium-3 and helium-4 isotopes.
