PURPOSE: A heater assembly is provided to have excellent indirect heating performance due to radiation of infrared rays and to have rapid heating rate. CONSTITUTION: A heater assembly comprises a housing, a heating plate(120), and a heating unit(130). Openings are formed in both ends of the housing. The heating plate is longitudinally installed inside the housing. The heating unit comprises a heating element and electrodes. The heating element is fixed in an insulator attached in one side of the heating plate. The electrodes are located in both sides of the heating element. On order to radiate heat from the heating element, the electrodes supply power. The heating element is covered by a protective layer. |
