Document Type and Number:
Japanese Patent JP2518137
Kind Code:
B2
Abstract:
PURPOSE: To provide a space thermal louver which is designed to reduce the generation of a mechanical stress owing to vibration and an impact during launching.
CONSTITUTION: A thermal louver comprises a mechanism consisting of a hold spring 1 to fix a louver blade 3 during launching and a shape memory spring 2 elongated when the temperature of a radiation plate 5 exceeds a specified value during launching; and a bimetal coil 4 to rotate the louver blade 3 around a louver blade rotary shaft 6 according to a temperature change. In an initial state, the generation of fixed vibration and the impact of the louver blade is reduced. Meanwhile, in a working state, it works like a conventional louver plate.
