Abstract

PURPOSE: To improve the cooling effect of an integrated circuit by mounting a plurality of integrated circuits in rows on a printed circuit board to pass cooling fluid through both sides of respective rows in such a manner that the integrated circuits are laterally displaced with respect to the flowing direction of the cooling fluid.
CONSTITUTION: A number of integrated circuits 2 are so mounted on a printed circuit board 1 to pass cooling fluid through both sides of respective rows as to retain the space for passing the cooling fluid at both sides of the rows. The integrated circuits 2 of the respective rows are so displaced laterally, for example, perpendicularly to the direction of the cooling fluid flow as not to exceed the width of the integrated circuits 2 at one every other circuits 2. Thus, there occur fluid pressure increase and decrease in the vicinity of both ends laterally between the integrated circuits 2a and 2b projected toward the cooling fluid flow to thereby cause induction stream 4 and longitudinal vortex 5 along the integrated circuits 2, and the integrated circuits 2 are accordingly uniformly and effectively cooled to reduce the size of high packing density mounting structure and to increase the integration of the integrated circuits 2.
