A device in connection with cooling of printed circuit boards, where the printed circuit boards are in a holder 1 in a cabinet 3, which device is constructed in such a way that for each holder a regulating plate 6 is placed across the stream of air, the regulating plate having a number of through holes 9, 10, 11 and/or slits 12, the size and position of which are determined in advance, and that the stream of air across the different printed circuit boards in a holder 1 is adapted to the required cooling need, dependent upon the amount of heat generated in the different printed circuit boards. <IMAGE>
