Flexible foil heaters are a proven technology and offer ideal solutions where large areas and low watt density are desired. The typical foil heater consists of a flexible heater wire bonded to a thin conductive substrate, usually aluminum. The substrate serves as a carrier for the wire and acts as a heat sink to maximize heat transfer.
Foil heaters offer a self-contained, one-piece assembly solution, which can be adhesively or mechanically mounted. They can be designed to match almost any surface geometry, conforming to irregular shapes and allowing for holes and cutaways. They can be flexible to semi-rigid, and terminated to be compatible with any connection scheme.
Foil Heater Construction Each foil heater is constructed to achieve optimum performance, allowing the heat to be
precisely placed. Various combinations of foil (chosen from a variety of thicknesses), insulation, and specially selected adhesive layers are bonded together with custom designed leads. Geometries are created to achieve the appropriate thermal and mechanical parameters, and terminations are chosen to be consistent with the power connection scheme. Both one- and two-sided heaters can be constructed.
Flexible Foil Heaters offer excellent heating solutions when you’re heating a large area and cost is a limiting factor. These heaters offer advantages where watt densities are low and surface contact is required.
