  2. Heating pad - Wikipedia

    en.wikipedia.org/wiki/Heating_pad

    A heating pad is a pad used for warming of parts of the body in order to manage pain. Localized application of heat causes the blood vessels in that area to dilate, enhancing perfusion to the targeted tissue. Types of heating pads include electrical, chemical and hot water bottles. Specialized heating pads (mats) are also used in other settings.

  3. Warm compress - Wikipedia

    en.wikipedia.org/wiki/Warm_compress

    A warm compress is a method of applying heat to the body. [1] Heating sources can include warm water, microwaveable pads, wheat packs and electrical or chemical pads. Some unorthodox methods can include warmed potatoes, uncooked rice, and hard-boiled eggs. The most common warm compress is a warm, wet washcloth. [2]

  4. Flameless ration heater - Wikipedia

    en.wikipedia.org/wiki/Flameless_ration_heater

    The instructions advise that the heater should rest against a "rock or something" The flameless ration heater is issued in a plastic bag with instructions printed on it. Inside the bag is a small quantity of metallic powders, which does the actual heating. To heat a meal, the bag is first torn open, and a sealed food pouch is placed inside.

    Thermal pads can be seen in several locations on this printed circuit board (PCB), in particular, the bottom pad of the three vertical pads in the top left corner. A thermal relief pad, thermal pad or simply thermal, is a printed circuit board (PCB) pad connected to a copper pour using a thermal connection. It looks like a normal pad with ...

  7. ThermaCare - Wikipedia

    en.wikipedia.org/wiki/ThermaCare

    ThermaCare is a type of Continuous Low-level Heat-wrap Therapy (CLHT), that activates upon contact with air, providing approximately eight hours of heat directly where the heat-wrap is applied. Thermacare heat-wraps are designed for specific applications, including neck or wrist pain, lower back pain, knee pain, and menstrual cramps.

  8. Hand warmer - Wikipedia

    en.wikipedia.org/wiki/Hand_warmer

    The release of heat is triggered by flexing a small metal disk in the hand warmer, which generates nucleation centers that initiate crystallisation. Heat is required to dissolve the salt in its own water of crystallisation and it is this heat that is released when crystallisation is initiated. [9] The latent heat of fusion is about 264–289 kJ ...

  9. Thermally conductive pad - Wikipedia

    en.wikipedia.org/wiki/Thermally_conductive_pad

    In computing and electronics, thermal pads (also called thermally conductive pad or thermal interface pad) are pre-formed rectangles of solid material (often paraffin wax or silicone based) commonly found on the underside of heatsinks to aid the conduction of heat away from the component being cooled (such as a CPU or another chip) and into the heatsink (usually made from aluminium or copper).
