Abstract
A heat-radiating structure of an electronic card unit is compact and reinforces a printed circuit board while improving heat radiation efficiency. Card unithas dual function reinforcing plate-heat dissipatersandat the upper and lower edges of a printed circuit boardon which a heat-generating componentis mounted.
