Abstract
The invention relates to a heating device comprising a housing (15), through which air to be heated can pass and which delimits a heating space controlled by a power supply control circuit connected to a power source. The heating space includes electric heating modules (14), each heating module consisting of a first and second metal tape (10, 10) that arc essentially parallel in a transversal direction (D) and of a positive temperature coefficient resistive elements (12) fixed between the two metal tapes.
Claims22
A heating device, comprising a housing (15) through which air to be heated can pass delimiting a heating space controlled by an electrical power supply control circuit connected to a power supply source,
- characterised in that the heating space comprises a plurality of electrical heating modules (14) mounted to the housing (15), each heating module being independently separable from the housing (15) and the heating space and including a first and a second approximately parallel metallic ribbon (10, 10′) along a transverse direction (D) and by resistive elements with a positive temperature coefficient (12) fixed between the two metallic ribbons,
- wherein the housing (15) also comprises power supply compartments (20) with a shape suitable for housing power supply modules (200) that can be connected to the electrical power supply control circuit and to a group consisting of at least one heating module (14), each power supply module comprising an electronic switching element (203), and
- wherein the power supply control circuit is arranged on one side of the housing, in a power supply control compartment (50), and wherein the power supply compartments (20) are arranged in parallel close to the control circuit along the transverse direction (D) with an equal spacing between each compartment.
A heating device according to any one of the previous claims, characterised in that the housing (15) includes heating compartments (16) shaped to house a number of heating modules (14) chosen as a function of the total required heating power.
