A heat pipe is a hollow tube containing a heat transfer liquid. The liquid absorbs heat and evaporates at one end of the pipe. The vapor travels to the other (cooler) end of the tube, where it condenses, giving up its latent heat. The liquid returns to the hot end of the tube by gravity or capillary action and repeats the cycle. Heat pipes have ...
A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.
A cast iron convector radiator from 1904. Heat transfer from a radiator occurs by two mechanisms: thermal radiation and convection into flowing air or liquid. Conduction is not normally a major source of heat transfer in radiators. A radiator may even transfer heat by phase change, for example, drying a pair of socks. In practice, the term ...
Liquid cooling systems are made up of a driving pump, a cold plate, and a fan-cooled radiator. [14] The heat generated by a high power LED will first transfer to liquids through a cold plate. Then liquids driven by a pump will circulate in the system to absorb the heat. Lastly, a fan-cooled radiator will cool the heated fluids for the next ...
The radiator must reject both the spacecraft waste heat plus any radiant-heat loads from the environment or other spacecraft surfaces. [9] Most radiators are therefore given surface finishes with high IR emittance (ε > 0.8) to maximize heat rejection and low solar absorption (α < 0.2) to limit heat loads from the
A loop heat pipe (LHP) is a two-phase heat transfer device that uses capillary action to remove heat from a source and passively move it to a condenser or radiator.LHPs are similar to heat pipes but have the advantage of being able to provide reliable operation over long distance and the ability to operate against gravity.
Turn the heat down when you're away. But setting your thermostat to a specific temperature and never changing it won't be good for your heating bills. Though about 70 degrees is ideal, it's unwise ...
