Abstract
A safe electrical heat energy generator which comprises a heater unit equipped with a set of systematically organized heat radiating metal fins. A feature of the invention is its reenforced compact structure in which a heating element arrangement and the heat radiating metal fin arrangement are manufactured as a single heater unit structure. In such a structure, a heating element is surrounded with an insulating layer and enclosed inside a central heat conductive tubing of the framework for the metal fin arrangement, thereby defining the major components of the heater unit. In this manner, the entire heater unit structure is the source of radiant heat energy, not simply the heating element itself.
Claims22
