Abstract
The present invention provides a plate-type heater designed to allow uniform generation of heat across the entire surface of the heater, comprising an upper component composed of a first outer covering and a first intermediate layer joined together and a lower component composed of a second outer covering and a second intermediate layer joined together, with a heating element being placed between said upper component and lower component and wires laminated onto the two end surfaces of said heating element.
Claims11
A method for manufacturing a plate-type heater, comprising,
- manufacturing an upper component and a lower component composed of joined outer coverings and intermediate layers;
- applying a heating element to the upper part of the entire surface of the lower component;
- and
- attaching wires, used to supply electrical energy, by lamination, to the ends of the heating element, and
- joining the lower component to which the heating element has been applied, to the upper component,
- in which the joining of the outer coverings and intermediate layers is carried out by extrusion lamination using a polyolefin resin.

A plate-type heater, comprising
- an upper component comprising a first outer covering and a first intermediate layer;
- a lower component comprising a second outer covering and second intermediate layer;
- said first outer covering and said first intermediate layer joined together by a polyolefin resin using an extrusion coating process;
- said second outer covering and said second intermediate layer joined together by a polyolefin resin using an extrusion coating process;
- a heating element comprising a first carbon compound layer, in a hardened form, placed between the upper component and the lower component and a second carbon compound layer laminated on the first carbon compound layer by gravure printing;
- conductive wires fusion bonded to both ends of the second carbon compound layer by lamination, without an adhesive, so that when electricity is passed to the conductive wire, the entire carbon compound layers are heated.
