Abstract
A ceramic heater having an enlarged windward area includes a conductive heat sink, at least one positive temperature coefficient (PTC) heating element, and an electrode plate. The conductive heat sink includes a cooling fin. The at least one PCT heating element is disposed on one side of the cooling fin. The electrode plate is disposed on the other side of the cooling fin. A conductive terminal protrudes from one end of the electrode plate. The conductive terminal includes a warped section and a flat section. A portion of the warped section and the flat section extend in a direction perpendicular to an extending direction of the electrode plate. Accordingly, heat dissipation is accelerated, a windward area is enlarged, and the effect of blowing out a hot airflow is enhanced, thereby avoiding a temperature rise of the conductive terminal.
