<p>The present invention relates to a heating apparatus of an instantaneous electric water heater. The apparatus includes a heat-radiating case which has a water inlet and a water outlet. A heat-radiating cover is provided at the opening at one end of said heat-radiating case and a ceramic sheet for radiating heat is securely connected at the lower end of the heat-radiating cover. The output end of said ceramic sheet for radiating heat is connected with the power supply lines which pass through said heat-radiating cover. After assembled, the ceramic sheet is immersed in the liquid contained in said heat-radiating case. The ceramic sheet for radiating heat is comprised of a ceramic sheet body and a printed thin film for radiating heat which is sintered in said ceramic sheet body. The present invention with this structure is endowed with such merits that its structure is simple, its thermal efficiency is high, the radiation of heat is uniform, as well as that its life span is long.</p> |
