PURPOSE:To enhance the heat utilization effect by forming a heat radiating surface consisting of metal wires in a certain length arranged at a constant spacing, and giving directionality to the heat radiation. CONSTITUTION:In such a way as half fitted in and half exposed to the atmosphere, a surface-shaped heat emitting member 1 is installed in a support 2 consisting of a heat insulating substance in a thickness of A so that the heat radiating surface will be convex or concave. This surface-shaped heat emitting member 1 has a heat radiating surface in an arbitrary form, e.g., a semi-circular, and the heat generated is released from an opening window O' to outside the device through direct radiation. The heat emitting member 1 is folded zigzag at certain lengths and arranged at a constant pitch P. This permits the heat to be radiated with directionality to provide good heating efficiency, and heat emitting wires can well be maintained without requiring heating of the support 2. |
