Abstract

A radiator, in particular for the use on motor vehicles, comprising a supporting body (1), where one or more heat emitting elements (2) extend between two first sides (1C) of said body, said heat emitting elements comprising one or more electric resistors, in particular positive temperature coefficient resistors, and being in contact with at least a heat dissipating element (4), the latter being in particular assembled mounted in said supporting body (1) in a substantially position with respect to the heat emitting element (2) in contact with it, where in said supporting body (1) elastic means (3) are further provided, which generate a thrust to press at least one of the dissipating elements (4) provided on at least one of the heat emitting elements (2), or vice-versa. According to the invention, said elastic means comprise at least one elastic device (3) located in an intermediate position between two dissipating elements (4) and/or two heat emitting elements (2) and/or a dissipating element (4) and a heat emitting element (2), being operative for pushing them towards respective opposite directions.
