IPC: F24H3/00
Filed: 1990-10-22
Abstract: PURPOSE:To attain a long life of a heat transmitting line and prevent a fire from being occurred by a method wherein an electrical heater has a structure in which air passes through an annular passage between an air flow restricting pipe and a cylindrical insulator. CONSTITUTION:An air flow restricting pipe 4 for use in restricting a flow speed of air flowing outside a cylindrical insulator 1 having a heating electrical line 2 wound therearound is disposed. As sir is forcedly flowed from an air inlet 9 to an annular passage 12 composed of the air flow restricting pipe 4 and the cylindrical insulator 1 and heated, the air is restricted by the air flow restricting pipe 4, its flow speed is made fast and a heat transmittance rate at the air is increased. A casing is of a double structure, air is forcedly flowed outside an inner casing 6 and then a heating calorie is recovered. Air fed from an air inlet 9 passes through the annular passage 12 composed of the inner easing 6, reversed at its end, passes through an opening of an inlet side heat generating supporter plate 3 positioned inside the inner casing 6. The air is heated at the annular passage 12 composed of the air flow restricting pipe 4 and the cylindrical insulator 1, passes through an opening of the outlet side heating supporter plate 3 and flows out of an air outlet port 10.
