Abstract:
1. An anti-condensate resistance with PTC thermistor that prevents the formation of condensate thereon, comprising: a) a central heat sink element, the central heat sink element comprising two dissipating plates which are mutually facing and continuously joined in such a way as to form, in a space interposed between the plates, a housing for inserting the PTC thermistor together with an element adapted to be secured inside the housing; b) a first and a second closing plugs for closing openings of the housing and for hermetically sealing the PTC thermistor inside the housing; wherein the dissipating plates have a cross-section that is centrally curved with a convex curvature, each one of the dissipating plates being equipped at their ends with inserting tracks adapted to form working portions, the working portions being adapted to be subjected to forces in order to permanently set joining sections of the dissipating plates, so that the dissipating plates are adapted to elastically press onto the PTC thermistor, at the same time cancelling the curvature of the dissipating plates in order to maximize a contact surface between the dissipating plates and the PTC thermistor in the housing and to block the closing plugs in the openings, each one of the dissipating plates being equipped on an external surface with a plurality of dissipating wings.
