Abstract:
1. A heating assembly for a heating, ventilating and/or air conditioning installation, especially for a cabin of a vehicle, which assembly comprises, in combination, a main radiator ( 1 ) for flow of fluid, including at least one manifold ( 2 , 2 ′) having ports ( 3 , 3 ′) for inlet and outlet of the fluid, between which there extends a plurality of tubes ( 4 ) for flow of the fluid therein, which are interposed between and along a plurality of finned elements ( 5 ) to define a heat exchange surface of the main radiator ( 1 ) relative to a direction of air flow, together with an electric radiator comprising a body defining a heat exchange surface of the electric radiator relative to the direction of air flow, which comprises at least one electrical heating member interposed between a plurality of finned elements ( 8 ) and having means ( 31 , 31 ′) for connection to an electrical source and to electronic control devices ( 28 , 29 , 30 ), the heating assembly further including means for assembling together the main radiator ( 1 ) and the electric radiator, characterised in that the heat exchange surface of the electric radiator is distinct from the heat exchange surface of the main radiator ( 1 ) with the body of the electric radiator is sub-divided into a plurality of independent heating elements ( 6 ) disposed adjacent to and upstream and/or downstream to at least one face of the main radiator ( 1 ) relative to the direction of air flow and assembled on a junction structure for joining the electric radiator on the at least one face of the main radiator ( 1 ), and the electronic control devices comprise at least one switch ( 29 ) associated with an electronic printed circuit board ( 30 ), with means for connecting at least one elementary body ( 7 ) of the heating elements ( 6 ) comprising a pair of connecting lugs ( 31 , 31 ′) for connection to a pair of profiled elements ( 32 , 32 ′) associated with the electrical power source of the vehicle, and in that the electronic printed circuit board ( 30 ) is fixed close to any one of the sides of the main radiator ( 1 ), the switch ( 29 ) being located indifferently on any one of the sides of the main radiator ( 1 ) or on one of the faces of the latter, and the elementary body ( 7 ) comprises a metal plate ( 26 ) having at least one resistive track ( 27 ).
