Stelrad is a British-based manufacturer of central heating radiators. Its Elite radiator is the most popular radiator in the United Kingdom. ... Radiators – it ...
Radiator production was ended at Stelrad's Hull site, and production was focused on boilers. [24] In 1989 the Metal Box company demergered, and MB group formed; Caradon was acquired by MB group becoming MB Caradon in 1989 and the Hull boiler factory became Caradon Ideal in 1993.
The folded unipole antenna is a type of monopole mast radiator antenna used as a transmitting antenna mainly in the medium wave band for AM radio broadcasting stations. It consists of a vertical metal rod or mast mounted over and connected at its base to a grounding system consisting of buried wires. The mast is surrounded by a "skirt" of ...
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.
An unsectionalized mast radiator is a monopole antenna, and its vertical radiation pattern, the amount of power it radiates at different elevation angles, is determined by its height compared to the wavelength = / of the radio waves, equal to the speed of light divided by the frequency .
Radiators first used downward vertical flow, driven solely by a thermosyphon effect. Coolant is heated in the engine, becomes less dense, and so rises. As the radiator cools the fluid, the coolant becomes denser and falls. This effect is sufficient for low-power stationary engines, but inadequate for all but the earliest automobiles.
