Abstract: 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).

Abstract: Electric heating device comprising an electric radiator (10) for heating the air passing through it, said radiator comprising a casing (12), at least one resistive element mounted in the casing and constituted by at least one zigzag metal strip (22) which is disposed so as to be directly exposed to the air passing through the casing, and a circuit (30) for controlling the electrical supply of the resistive element or elements connected to a power supply. The electric radiator (10) comprises a set of individual heating modules (20) disposed parallel to one another in the casing (12) and so as to be directly exposed to the air passing through the casing, each heating module (20) comprising a pleated or corrugated metal strip (22) and an electronic switch controlled by the control circuit (30) intended to selectively inhibit the electrical supply of the metal strip (22).

Abstract: Part for supporting an item of equipment, comprising support ribs, and method of molding said part The support part has support ribs for holding an item of equipment, in particular an electric motor for a motor vehicle. A mold consisting of at least two cores is provided. These cores are brought toward one another in a direction (D) such that they are in contact with one another along a parting plane. The mold is filled with a moldable material and the cores are moved apart from one another in the given direction (D). The support ribs are provided on the molded part with an angle of inclination with respect to the given direction (D). The ribs follow the parting plane. A clearance is provided in the region of the parting plane between the cores in order to form the ribs during molding.

Abstract: A heating and/or air-conditioning installation with a motor-driven fan unit has a motor driving a turbine, a speed control module and a volute housing the motor and forming an outlet channel for airflow at the periphery of the turbine. The speed control module is mounted at the periphery of the motor and has an electrical connector engaging a connector of the motor. It also has one or more walls of thermally conducting material and in contact with the outlet channel to cool the module.
