A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [1] [2] [failed verification] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters.
An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm. No contact or medium between the emitter and cool ...
SPH smart dog house Recent advancements in technology have led to the development of smart dog houses, which offer features such as temperature control, automatic doors, and environmental monitoring. These smart shelters can automatically adjust temperature, humidity, and air quality to ensure pets' comfort, with some models also allowing ...
In buildings, the radiant heat flow between two internal surfaces (or a surface and a person) is influenced by the emissivity of the heat emitting surface and by the view factor between this surface and the receptive surface (object or person) in the room. [38] Thermal (longwave) radiation travels at the speed of light, in straight lines. [9]
A positive-temperature-coefficient heating element (PTC heating element), or self-regulating heater, is an electrical resistance heater whose resistance increases significantly with temperature.
A heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. [1] Heat is generated by the passage of electric current through a resistor through a process known as Joule heating. Heating elements are used in household appliances, industrial equipment, and scientific ...
A TE device made by two ceramic plates can be integrated into a high power LED and adjust the temperature of LED by heat-conducting and electrical current insulation. [10] Since ceramic TE devices tend to have a coefficient of thermal expansion mismatch with the silicon substrate of LED, silicon-based TE devices have been invented to substitute ...
Radiant space heaters transfer heat directly to bodies in front of them using thermal radiation. Thermal radiation is a process by which objects at a high temperature emit heat in the form of electromagnetic waves. These heaters are often designed such that the frequency of the emitted waves are in the infrared part of the electromagnetic spectrum.
