Closable radiator grid for an armored vehicle

摘要

A closable radiator grid for an armored vehicle which comprises two frames which have a plurality of parallel plates, wherein one frame is closed with respect to the other in a partition plane transverse to the direction of the plates. In order to disturb the rate of passage of cooling air as little as possible and seal it well, the plates of the two frames are inclined, in cross section, in opposite directions by an angle, the thickness of the plates at the partition plane being greater than the width between the plates of the same frame and form a convergent-divergent flow channels in their open state between the plates of the two frames which are aligned with each other.
