Abstract
The present invention relates to a heating device for heating air and to radiator subassemblies and positioning frames and further relates to a method for mounting a heating device according to the invention. The positioning frames comprise means for snap-fittingly anchoring radiator elements and electrode sheets, thereby permitting an easy joining to obtain radiator subassemblies which can subsequently be arranged in layers or stacked in an easy manner. A heating device is thereby created with improved assembling properties. PTC elements are used as the heating elements.
Claims42
Heating device for heating air, the heating device comprising at least one radiator element and at least one positioning frame;
- said at least one positioning frame arranged for being fixed to said at least one radiator element;
- said at least one positioning frame comprising means for receiving at least one PTC (Positive Temperature Coefficient) element;
- said at least one positioning frame further comprising means for clipping a radiator element to both sides of the positioning frame.
Method for assembling a heating device, the method comprising the steps of:
- connecting radiator sheets to lamella elements for prefabricating radiator elements;
- clipping the prefabricated radiator elements and/or electrode sheets to positioning frames and inserting PTC elements for prefabricating radiator subassemblies;
- stacking the prefabricated radiator subassemblies;
- and
- enclosing the stacked radiator subassemblies in a holding frame.
Positioning frame comprising:
- means for receiving at least one PTC (Positive Temperature Coefficient) element;
- and
- means for clipping a radiator element to both sides of the positioning frame.
A radiator subassembly comprising:
- a radiator element;
- and
- a positioning frame clipped to the radiator element;
- the positioning frame comprising
- means for receiving at least one PTC (Positive Temperature Coefficient) element, and
- means for clipping said radiator element to both sides of the positioning frame.
