  2. Overheating (electricity) - Wikipedia

    en.wikipedia.org/wiki/Overheating_(electricity)

    Heat sinks are often attached to portions of the circuit that produce most heat or are vulnerable to heat. Fans are also often used. Some high-voltage instruments are kept immersed in oil. In some cases, to remove unwanted heat, a cooling system like air conditioning or refrigerating heat-pumps may be required.

  4. Superheating - Wikipedia

    en.wikipedia.org/wiki/Superheating

    Superheating is more likely after repeated heating and cooling cycles of an undisturbed container, as when a forgotten coffee cup is re-heated without being removed from a microwave oven. This is due to heating cycles releasing dissolved gases such as oxygen and nitrogen from the solvent. There are ways to prevent superheating in a microwave ...

    A video showing a "heating pad" in action A video showing a "heating pad" with a thermal camera. A phase-change material (PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat or cooling.

  6. Heater core - Wikipedia

    en.wikipedia.org/wiki/Heater_core

    A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface area for heat transfer to air that is forced past them by a fan, thereby ...

    Positioning the laptop on the thighs can allow for direct exposure to the heating elements of the laptop, which include the central processing unit (CPU) and the graphics processing unit (GPU). [5] At least 15 cases have been reported by 2012 with the condition usually affecting the left anterior thigh. [ 5 ]
