Abstract

A cooling device according to the present invention, in which a space is formed by means of flat electrodes and side plates disposed on the ends of the flat electrodes, and a flexible film fastened in that space in a shape of the letter S, is fixed to a semiconductor package so that one of the flat electrodes is fitted on the semiconductor package. The respective flat electrodes are alternately powered to move the S shaped section of the flexible film.
