Embodiment Construction

[0029] figure 1 An electrical heating device 1 according to the invention is schematically shown. The electric heating device mainly consists of two components linked to each other differently: the heating body 2 and the control module 3 .

[0030] The heating body 2 comprises a tube bundle 4 for passage of a fluid to be heated, which can be a gaseous fluid or a liquid fluid. In the case of a ventilation and heating installation for motor vehicles, the gaseous fluid is an air flow which is conveyed in the installation and reheated via the heat dissipater 9 . In this same facility, the liquid fluid can also be water with added glycol, which is circulated in the cooling system.

[0031] The heating body 2 continues beyond the tube bundle 4 by a wall 5 forming the edge of a cavity 6 delimiting an interior space in which the control module 3 is installed.

[0032] The heating body 2 comprises a plurality of housings 7 which receive at least one electric heating element 8 . fig...

Abstract

The invention relates to an electric heating device (1) comprising a heating body in which at least one electric heating element (8) is mounted, the operation of which depends on a control module (3) which constitutes the heating device , the heating body (2) comprises a wall (5) which at least partially defines a cavity (6) in which the control module (3) is housed, characterized in that , the electric heating element ( 8 ) and the control module ( 3 ) are adapted to be supplied with a so-called low voltage between 80 and 600 volts, and in that an electrical insulation ( 17 ) is provided, which electrical insulation ( 17 ) Covers the wall (5) defining the cavity (6).

Description

technical field [0001] The technical field of the invention is that of ventilation, heating and / or air conditioning equipment installed on vehicles propelled by electric motors. The invention is more specifically aimed at electric heating devices installed in these devices and passed through by the air flow contained by the housing of the device. Background technique [0002] The increasing scarcity of oil resources has led automakers to develop vehicles that operate on new energy sources. Propulsion of vehicles by electric energy is a solution that presents an interesting alternative, and it is necessary to install batteries to store and supply this electrical energy to the electric motors that propel the vehicle. [0003] Vehicles currently equipped with an internal combustion engine ensure that the passenger compartment is heated by all or some of the fluid ensuring cooling of the internal combustion engine. This coolant heats up when it comes into contact with the inte...
