Title:
MULTI-STAGE TYPE THERMAL LOUVER
Document Type and Number:
Japanese Patent JPS58221416
Kind Code:
A
Abstract:
PURPOSE:To improve heat dissipating/insulating properties and the insulating properties against sunlight, by arranging multi-stage blade arrays in the flowing direction of heat from a dissipating surface to the outer space and reversing the rotational directions of the blade arrays on the stages adjacent to each other. CONSTITUTION:The blade arrays 3 constitutes two stages; the outer blade array rotates in the counterclockwise direction from a position perpendicular to the fully opened dissipating surface 1 and the inner blade array 3 rotates in the clockwise direction. In an intermediate position, sunlight made incident from both right and left directions are considerably reflected by any blade array, so that no direction permits the sunlight to fall directly upon the dissipating surface 1. When the dissipating surface 1 is fully closed, the insulating properties are obtained by two specular surface plates, and when fully opened, the dissipating surface 1 is almost exposed to the outer space and high dissipating properties are obtained.
