摘要:
A frame for receiving a heating element for an electric heater of a ventilating, heating and/or air conditioning unit of a vehicle, in particular. The frame is shaped in the form of a hollowed-out box whose large faces, intended to be traversed by airflow conveyed by the unit, are held at a distance from each other in order to create between them a space for receiving the heating element. The frame is made of a single part in which means for holding the heating element inside the space are located in the area of the large faces.

The invention is directed to a heating assembly comprising, in combination, a main radiator (1) for fluid flow and an electric radiator. The latter is disposed on one face of the main radiator (1) defining its general plane, and consists of a plurality of independent heating elements (6). Each of these heating elements (6) comprises an elementary electrical heating body (7), having connecting means (31, 31′) for connection to an electrical power source, and a finned element (8). These heating elements (6) are assembled on a connecting structure of the electric radiator on the face of the main radiator (1).

The object of this invention is a frame (1) for receiving a heating element (3) for an electric heater of a ventilating, heating and/or air conditioning unit of a vehicle, in particular. This frame (1) is shaped in the form of a hollowed-out box whose large faces (2. 2′), intended to be traversed by the airflow (A) conveyed by the unit, are held at a distance from each other in order to create between them a space (12) for receiving the heating element (3). The frame (1) is made of a single part in which means for holding (15) the heating element (3) inside said space (12) are located in the area of said large faces (2, 2′).
摘要:
Two stop valves, associated with bypass ducts containing energy absorbing devices, enable an adjustable fraction of the hot fluid to be diverted past left and right hand heating radiators, so that any change in the adjustment of the fluid flow in either of the radiators has no effect on the fluid flow in the other radiator.
