Abstract

PROBLEM TO BE SOLVED: To provide a radiator for an optical panel element to let a uniform air current from a slit of a guide pipe flow along a surface of a panel element, improve efficiency of heat radiation and prevent noise and loss of air current pressure caused by turbulence. SOLUTION: The radiator for the optical panel is composed of a fan 1 providing an exit 11 and a guide pipe 2. One end of the guide pipe 2 is connected to the exit 11 and provides the slit 21 on another end. The slit 21 corresponds to the lower end of the surface 31 of the panel element 31. The uniform air current from the slit 21 can flow along the surface of the panel element.
