Definitions

  • the present invention relates to a radiating convection heating apparatus.
  • heater fans are already commercially available and are substantially constituted by an electric resistor arranged in a flow of air generated by a fan which thereby facilitates the rate of heat exchange from the resistor toward the environment, as see for example DE-U-6 906 398.
  • radiators are also known; said radiators are substantially constituted by a body which is composed of a plurality of columns which in practice define a chamber for containing diathermic oil which is heated by a resistor which is generally arranged in a lower part of the chamber (for example, EP-A-0 292 441).
  • the aim of the invention is indeed to solve the above described problem by providing a radiating convection heating apparatus which, despite having a mass of diathermic oil which is heated by a resistor, allows to also use a forced ventilation which facilitates heat exchange without thereby creating non-uniformities in heating.
  • a particular object of the invention is to provide a heating apparatus which allows to optimize heat exchange by using forced ventilation, achieving a significant increase in the outward production of heat.
  • Another object of the present invention is to provide a heating apparatus which allows to humidify the environment, thus restoring the natural equilibrium in said environment.
  • Not least object of the present invention is to provide a heating apparatus which can be easily obtained starting from commonly commercially available elements and materials and is furthermore competitive from a merely economical point of view.
  • a radiating convection heating apparatus which comprises two side wall compartments between which a plurality of column-like elements is arranged, said elements extending between a lower manifold and an upper manifold so as to define a containment chamber for diathermic oil which can be heated by means of an electric resistor, characterized in that it comprises a fan the delivery whereof is connected to a heat exchange duct which extends inside said upper manifold and exits at one of said side wall compartment.
  • the radiating convection heating apparatus which is generally indicated by the reference numeral 1, comprises two side wall compartments, respectively indicated by 2 and 3, which are advantageously but not necessarily mounted on castors 4. Between the side wall compartments 2 and 3 there is a plurality of column-like elements 5 which extend between a lower manifold 6 and an upper manifold 7, so as to define a chamber for diathermic oil which can be heated by means of an electric resistor which is generally arranged at the lower manifold 6.
  • An important peculiarity of the invention is constituted by the fact that in one of the side wall compartment, for example in the side wall compartment 2, there is a fan 10, the intake whereof is arranged at an opening 11 which allows to draw air at the interspace defined in the side wall compartment, so that the air is drawn in from below and is preheated by striking the face of the side wall compartment which is directed toward the heating elements.
  • the fan 10 is provided with an impeller 12, of a per se known type, advantageously with radial vanes, which feeds the flow of drawn air into a delivery duct 15 which is accommodated inside the side wall compartment 2 and is connected, in an upward position, to a heat exchange duct 20 which extends inside the upper manifold 7, so that in practice the air strikes the heating body from the inside, so that it undergoes an easy heating without dispersions or non-uniformities of flow toward the outside.
  • an impeller 12 of a per se known type, advantageously with radial vanes, which feeds the flow of drawn air into a delivery duct 15 which is accommodated inside the side wall compartment 2 and is connected, in an upward position, to a heat exchange duct 20 which extends inside the upper manifold 7, so that in practice the air strikes the heating body from the inside, so that it undergoes an easy heating without dispersions or non-uniformities of flow toward the outside.
  • the heat exchange duct 20 exits at a grille 21 which is directed outward and is advantageously provided on the other side wall compartment 3.
  • the heating apparatus comprises a humidification unit, generally indicated by the reference numeral 30, which is constituted by a storage tank 31 and by a humidification tank 32 which are mutually connected by means of a lower duct 33 so as to obtain in practice two communicating vessels.
  • a humidification unit generally indicated by the reference numeral 30, which is constituted by a storage tank 31 and by a humidification tank 32 which are mutually connected by means of a lower duct 33 so as to obtain in practice two communicating vessels.
  • a heating resistor 34 for humidification which can be independently powered and allows to create steam in a limited region of water, since in practice only the humidification tank is heated, allowing a good delivery of humidification steam, which escapes by means of an upper grille, generally indicated by 40.
  • the materials employed, as well as the dimensions and the contingent shapes may be any according to the requirements.
