US Patent 7335855 Electric PCB heating component, electronic circuit board and heating method

An electric PCB heating component for a heating electric component is coupleable to an electronic circuit board. The PCB heating component includes a fastening element, a heating element for generating thermal energy, and a heating body. The heating body emits thermal energy via a heat radiating surface. For a low cost PCB heating component, the heating element is a PTC heating element. A plurality of heating projections of the heating element cooperate to form a relatively large heat radiating surface such that thermal energy can be emitted in a substantially directional mode. The heating projections can be convection or radiation elements.
