Printed circuit board (PCB) with space saving cooling element for mounted electric component, containing tubular element forming duct for cooling air draught, with heat convection part for tubular element

摘要

PCB comprises cooling element for mounted electric components, which contains tubular element (re)forming duct for cooling air draught. There is heat convection part (WV) for tubular element with one or more PCB mounted components. Tubular element is so located on PCB that it is vertical to earth surface on insertion of PCB. Preferably fan is allocated to tubular element. Outer surface (AO) of tubular element may be silver-plated, while its inner surface (iO) may be black.
