2. Space Shuttle thermal protection system - Wikipedia

   en.wikipedia.org/wiki/Space_Shuttle_thermal...

   The key to a reusable shield against this type of heating is very low-density material, similar to how a thermos bottle inhibits convective heat transfer. [citation needed] Some high-temperature metal alloys can withstand reentry heat; they simply get hot and re-radiate the absorbed heat.

3. 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).

4. Heat shield - Wikipedia

   en.wikipedia.org/wiki/Heat_shield

   In engineering, a heat shield is a component designed to protect an object or a human operator from being burnt or overheated by dissipating, reflecting, and/or absorbing heat. [1] The term is most often used in reference to exhaust heat management and to systems for dissipating frictional heat.

5. Passive cooling - Wikipedia

   en.wikipedia.org/wiki/Passive_cooling

   Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process. [7]

8. Kerosene heater - Wikipedia

   en.wikipedia.org/wiki/Kerosene_heater

   The Japanese non-vented "fan" heater burns kerosene gas and is known as a gasification type heater. The liquid kerosene fuel is pre-heated via an electric heating element to vaporize the fuel. The resulting gas is collected and forced into the burn chamber where it is ignited and burns with a blue flame, similar to propane.
