A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops. The thermal switch may be a bimetallic strip, often encased in a tubular glass bulb to protect it from dust or short circuit. Another common design ...
Cycling dryers (also known as thermal mass dryers) utilize a thermal mass, usually a tank of water, to store the energy produced by the refrigeration system. The temperature of the water controls the refrigeration system through a thermostat. The compressed air passes through the thermal mass via a water cooled heat exchanger.

Despite its high stability, cast iron remains unsuitable for use as a normal surface plate in high-tolerance production applications because of thermal expansion. The nature and use of a master surface, by contrast, already necessitates expensive measures to control temperature regardless of material choice, and cast iron becomes preferable.
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.
Insulation is achieved by slowing the transfer of thermal energy (heat) to or from a component. This is achieved by insulating the component with materials that have a high r-value, which measures how well a material resists conductive flow of heat. The external layer of a removable insulation blanket is typically durable, made with a material ...
For the same amount of heat exchanged, the size of the plate heat exchanger is smaller, because of the large heat transfer area afforded by the plates (the large area through which heat can travel). Increase and reduction of the heat transfer area is simple in a plate heat-exchanger, through the addition or removal of plates from the stack.
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 ...
