description PURPOSE:To increase heat transmission efficiency and to increase cooling effect by installing small projections perpendicularly intersecting or slantingly intersecting to the cooling gas flowing direction at specified intervals over the whole length of passage on the upper and lower walls of passages in a cooling plate. CONSTITUTION:Small projections 5 perpendicularly intersecting to the cooling gas flowing direction are installed at specified intervals over the whole length of passage on the upper and lower inner walls of a cooling gas passage 4. The height of the small projection 5 is about 1/10 the height of the passage and its thickness is about twice the projection height. Intervals between the small projections is about 10 times the projection height. The small projections 5 arranged in the passage 4 disturb straight flow of cooling gas and act as a turbulent flow accelerator which generates small eddies. A cooling gas repeadedly strikes against the passage inner wall and heat transmission efficiency is increased.
