Abstract (en)
[origin: EP0880003A2] The grill covering the radiator of an armoured vehicle, which can be opened and closed, has two frames (7,8) where the blades (11,12) are aligned against each other in opposite angles (16,17) in cross section. The thickness (18) of the blades (11,12) on the dividing plane (15) is larger than the gap (19) to the next blade (11,12) in the same frame. In the open position, converging-diverging flow channels (22,23) are formed between the blades (11,12) aligned between each other in both frames (7,8).
