Abstract: An oil radiator structure particularly for heating rooms has a main body which is defined by a plurality of mutually associated radiating elements, inside which a hot fluid circulates, each radiating element includes at least one shaped plate-like element which has heat propagation formations suitable for reducing the heat on its outer surface and for simultaneously increasing the efficiency of the radiating element.

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.

Abstract: The device for emulsifying steam and milk particularly for cappuccinos and the like includes a first duct and a second duct for conveying milk and steam respectively and a device for mixing and emulsifying the milk with the steam; the mixing and emulsifying device is formed by a single chamber which is connected to the atmosphere and is provided with an element for conveying the first duct into the second duct for the simultaneous delivery, from a single outlet of the conveyance element, of milk and steam at a preset distance from the bottom of the chamber.
