Abstract
A heating unit and a method of fabricating the heating unit are provided. The heating unit includes a heating member provided in a tube, with an outer surface of the heating member spaced apart from an inner surface of the tube. The heating member may be connected to an external power source by a metal piece, rod, and a connecting unit sequentially coupled to the heating member. The heating member, connecting unit and rod provide a stable positioning of the heating member in the tube during thermal expansion of the heating member, thus preventing contact therebetween.
