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.
