The present invention relates to an electric auxiliary heating device () for heating a flow of air passing through in particular a conduit of a ventilation, heating and/or air conditioning installation of a motor vehicle, the auxiliary heating device comprising a casing that houses at least one heating module, said casing comprising: &#x2218;a heating compartment of which a first end () comprises an opening () and &#x2218;a connection interface () comprising: &#x25aa;a first plate () that is essentially planar and extends essentially parallel to the opening so as to cover said opening, and &#x25aa;a sheath () that extends in projection from the first plate () opposite the heating compartment, &#x25aa;slots () passing through the first plate () and opening inside the sheath (), the connection interface () comprising, on its internal face () that is oriented toward the heating compartment, at least one insertion stub () of which at least one of the edges facing the slots () is chamfered.

Electric auxiliary heating device

The invention relates to a device () for electrically heating fluid for a motor vehicle, said heating device () comprising at least one heating module () for heating said fluid, said at least one heating module () comprising a central core () and a heating element () defining a guide circuit () that guides the fluid between said heating element () and said central core () such that said at least one heating module () comprises at least one disturbing element () arranged in the fluid guide circuit () around the central core () and able to disturb the flow of said fluid. The invention also relates to a heating, ventilation and/or air conditioning apparatus () for a motor vehicle that comprises such an electrical heating device ().

Electrical heating device for a motor vehicle, and associated heating, ventilation and/or air conditioning apparatus

The invention relates to an electrical liquid heating device for a motor vehicle. The heating device comprises at least a first () and a second () heating module for heating the aforementioned liquid, defining at least one circuit () for guiding the liquid to be heated. The device is characterized in that the heating modules () each have a generally cylindrical shape and are arranged side by side substantially in parallel. The invention also relates to a heating and/or air-conditioning unit for a motor vehicle, comprising such a heating device ().

Electrical heating device for a motor vehicle and vehicle and associated air-conditioning and/or heating unit

The invention relates to a device for thermally conditioning a fluid for a motor vehicle, comprising: at least one heat module comprising a core and a shell defining a circuit for guiding the fluid that is to be heated or cooled between the core and the shell, a fluid inlet box () and a fluid outlet box, the inlet box () having at least one fluid inlet canal () communicating with the fluid guiding circuit. According to the invention, the fluid inlet canal () has at least one substantially curved portion which is configured to generate a swirling movement in the fluid. The invention also relates to a heating and/or air conditioning apparatus comprising such a device.

Device for thermally conditioning fluid for a motor vehicle and corresponding heating and/or air conditioning apparatus

The invention relates to a device for electrically heating fluid for a motor vehicle, characterized in that it comprises: at least one heating module () comprising at least one heating element () and defining a circuit () for guiding the fluid to be heated; a means () for controlling the heating element (), comprising an electric current switch () connected to said heating element () and a heat sink () having a first surface (), which is to contact the fluid, and a second surface (), which is to contact a sole plate () of said electric current switch (). The invention also relates to a heating and/or air-conditioning apparatus for a motor vehicle, including at least one such electric-heating device ().

Device for electrically heating fluid for a motor vehicle, and related heating and/or air-conditioning apparatus

The invention relates to an electrical heating device () including a heating body in which at least one electric heating element () is installed, the operation of said electric heating element being dependent on a control module () constituting the heating device, the heating body () including walls () at least partially defining a cavity () in which the control module () is accommodated, characterized in that the electrical heating element () and the control module () are suitable for being supplied with a so-called low voltage of between 80 and 600 volts, and in that an electrical insulator (), which covers the walls () defining the cavity, is provided.

Heat exchanger having electric heating elements

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.

Frame for holding heating elements of an electric heater of a ventilating, heating and/or air conditioning unit

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

Heating assembly for a heating, ventilating and/or air conditioning installation for a vehicle cabin

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.
