2. Space heater - Wikipedia

   en.wikipedia.org/wiki/Space_heater

   Convective space heaters utilize convection to transfer heat from the power source to a space. These heaters typically either rely on natural or forced convection.Natural convection is a phenomenon where temperature variations in an environment generate fluid flow.

3. Radiator (heating) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(heating)

   Radiators and convectors are heat exchangers designed to transfer thermal energy from one medium to another for the purpose of space heating. Denison Olmsted of New Haven, Connecticut, appears to have been the earliest person to use the term 'radiator' to mean a heating appliance in an 1834 patent for a stove with a heat exchanger which then ...

4. Spacecraft thermal control - Wikipedia

   en.wikipedia.org/wiki/Spacecraft_thermal_control

   The thermal control subsystem can be composed of both passive and active items and works in two ways: Protects the equipment from overheating, either by thermal insulation from external heat fluxes (such as the Sun or the planetary infrared and albedo flux), or by proper heat removal from internal sources (such as the heat emitted by the internal electronic equipment).

5. Radiator - Wikipedia

   en.wikipedia.org/wiki/Radiator

   The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, [1] [2] having received a radiator patent in 1857, [3] but American Joseph Nason and Scot Rory Gregor developed a primitive radiator in 1841 [4] and received a number ...
