Abstract

PURPOSE: To prevent incidence of a sunlight upon a heat collecting plate by applying a stress for deformation of a shape memorizing metal directly connected with a reflector while a heat collecting plate is overheated.
CONSTITUTION: A reflector 3 is divided into two part, a shape remembering metal 4 is sticked on a heat collecting plate 2 with its one end fixed to the heat collecting plate, and the divided reflectors are connected with the metal 4, which are lifted up through spring force while a system is overeated. If the heat collector 2 is made of copper, the spring force of the shape remembering metal is actuated when the metal is overheated to a temperature of about 200°C, and the reflectors 3 are restored to an original positon when its temperature goes down to a temperature of about 150°C. The shape memorizing metal 4 can be wound round a heat collecting tube without dividing the reflector 3. An external control causes to make a system prevent overheating of the heat collecting plate 2 unnecessary,as the reflector 3 can be moved automatically depending on a temperature.
