  2. Heat gun - Wikipedia

    en.wikipedia.org/wiki/Heat_gun

    A heat gun is a device used to emit a stream of hot air, usually at temperatures between 100 and 550 °C (373 and 823 K; 212 and 1,022 °F), with some hotter models running around 760 °C (1,030 K; 1,400 °F), which can be held by hand. Heat guns usually have the form of an elongated body pointing at what is to be heated, with a handle fixed to ...

  3. Thermal wheel - Wikipedia

    en.wikipedia.org/wiki/Thermal_Wheel

    Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...

  4. 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.

  5. Heat press - Wikipedia

    en.wikipedia.org/wiki/Heat_press

    A new style of press that is semi-automatic has entered the market as well, allowing for a manual closing process with an automatic, electromagnetic opening. Digital technology in newer machines enables precise control of heat and pressure levels and timing. The most common types of heat press employ a flat platen to apply heat and pressure to ...

  6. Heat spreader - Wikipedia

    en.wikipedia.org/wiki/Heat_spreader

    A heat spreader is generally used when the heat source tends to have a high heat-flux density, (high heat flow per unit area), and for whatever reason, heat can not be conducted away effectively by the heat exchanger. For instance, this may be because it is air-cooled, giving it a lower heat transfer coefficient than if it were liquid-cooled.

  7. Hot air oven - Wikipedia

    en.wikipedia.org/wiki/Hot_air_oven

    The standard settings for a hot air oven are: 1.5 to 2 hours at 160 °C (320 °F) 6 to 12 minutes at 190 °C (374 °F)....plus the time required to preheat the chamber before beginning the sterilization cycle. If the door is opened before time, heat escapes and the process becomes incomplete.

  8. Condenser (laboratory) - Wikipedia

    en.wikipedia.org/wiki/Condenser_(laboratory)

    A glass still head, upside down. The rounded part was meant to be fitted on the top of the boiling flask. Black-and-white photo of object at the Wellcome Trust museum. The still head is another ancient type of air-cooled condenser. It consists of a roughly globular vessel with an opening at the bottom, through which the vapor is introduced.

  9. Dilution refrigerator - Wikipedia

    en.wikipedia.org/wiki/Dilution_refrigerator

    On its way up, the cold, dilute 3 He cools the downward flowing concentrated 3 He via the heat exchangers and enters the still. The pressure in the still is kept low (about 10 Pa) by the pumps at room temperature. The vapor in the still is practically pure 3 He, which has a much higher partial pressure than 4 He at 500–700 mK.
