Abstract
An internally temperature controlled heat blanket. The heat blanket includes an outer layer of protecting foam fiberglass that affords operator safety, a layer of closed cell silicone foam which provides thermal and electrical insulation, a layer of thermally conductive mesh, another layer of thermally conductive silicone with holes cut into it, the holes containing positive temperature coefficient (PTC) heating elements, another layer of conductive mesh, a layer of thermally conductive silicone, and an inner layer of moderately conductive cured silicone or foam.
