Electric heating device, in particular for a vehicle heating and/or air-conditioning apparatus
First Claim
1. An electric heating device comprising:
- an electric radiator comprising a set of individual heating modules and a casing;
at least one resistive element constituted by at least one zigzag metal strip mounted in the casing;
a power supply;
a resistive element or elements connected to the power supply;
a control circuit for controlling the electrical supply of the resistive element or elements;
wherein each heating module (20) comprise a pleated or corrugated metal strip (22) and an electronic switch (25) controlled by the control circuit, wherein the pleated or corrugated metal strip (22) and the electronic switch (25) selectively inhibit the electrical supply of the metal strip (22), wherein each heating module (20) also comprises an insulating support (40), and the insulating support (40) comprises a molded rail (45) to hold the metal strip (22) in position, andwherein when air passes through the radiator the at least one zigzag metal strip is disposed so as to be directly exposed to the air passing through the radiator and wherein the in individual heating modules (20) are disposed parallel to one another in the casing.

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).
