Abstract (en)

The present invention is relative to a fluid heating device, suitable for heating at least one fluid circulating inside a heating structure, comprising at least one enclosure (10) made of a conductive material, inside which at least one resistive element is inserted, having respective terminals connected to relative electrical conductors connected to a power electronic circuit, the power electronic circuit is provided with at least one power switch (3), which is connected in turn, to at least one resistive element and to the power circuit; the electrical conductors emerge from said enclosure (10) passing through a fitting (1), which is placed coaxially with respect to the enclosure (10) and which is made of thermally conductive material; the power switch (3), made internally to said fitting (1), comprises a power dissipating element or diffuser (2), fixed and interposed between the power switch (3) and at least a portion of the inner walls (13) of the fitting (1) or the enclosure or pipe (10)
