Abstract
An oil radiator, particularly for heating rooms, includes a main body defined by a plurality of mutually associated radiating elements in which a diathermic oil heated by an electric resistor circulates. Each radiating element includes a pair of mating shaped plate-like elements joined together by welding to form an oil receiving space therebetween and each having lateral surfaces provided with a series of folds which mate with the corresponding folds of the other plate-like element to define a channel-shaped air flow compartment capable of lowering the surface temperature of the oil radiator below that of the oil contained in the radiator, thus reducing burn injuries caused by inadvertent contact with the radiator. The folds also cooperate to provide the radiator with planar lateral outer surfaces to minimize impact injuries caused by collision with the radiator. During operation cold air flows upwardly through the channel-shaped compartments and is heated so that the radiator propagates heat by convection and radiation.
