A standoff assembly for use in terminating a plurality of resistive heaters disposed within a fluid vessel includes a pressure adapter plate, an electrical enclosure adapter plate, and a plurality of conduits. An end portion of each of the resistive heating elements extends through the pressure adapter plate. The electrical enclosure adapter plate is spaced apart from the pressure adapter plate to define a dry volume therebetween. The conduits are secured to the pressure adapter plate and the electrical enclosure adapter plate. Each conduit is aligned concentrically with each of the resistive heating elements. An electrical termination portion of each resistive heating element is disposed within the conduit.

The invention relates to a device for electrically heating (1) a liquid, comprising a heating body (11), and a housing (3) defining, at least in part, a chamber (30) for circulating the liquid, the heating body (11) comprising at least one electric heating element (7, 9) extending in the chamber (30) and attached to an inner wall of the device defining, at least in part, the chamber (30) for circulating the liquid, so as to form a first mechanical connection. According to the invention, the electric heating device (1) comprises at least one mechanical connecting element (21) arranged in the chamber (30) and mechanically connecting the at least one electric heating element (7, 9) to an inner surface of the housing (3) extending opposite the heating body (11), so as to form a second mechanical connection separate from the first mechanical connection.

An electric heater for heating a liquid or frozen substance in a motor vehicle. In particular, an electric heater for heating electric car batteries or an HVAC system or for a system for reducing the environmental pollution of the motor vehicle. The electric heater includes a metal sheet adapted to generate heat when it is crossed by an electric current. two polymeric layers between which the metal sheet is arranged, and two metal layers, between which the two polymeric layers are arranged. The two metal layers are hermetically sealed to each other defining a casing, which prevents the substance to be heated from coming into contact with the two polymeric layers and with the metal sheet. A plurality of metal flaps extend transversely from an external face of at least one metal layer of the two metal layers.
