Abstract
Abstract A mobile current consumer device, especially a fire control device for artillery- and/or rocket weapons, comprising a current generator unit insertable into a receiving compartment thereof. In the installed condition of the current generator unit, at least two spatially separated cooling air currents can be delivered to the current generator unit, and removed in the form of heated air currents spatially separated from one another. The one cooling air current can be delivered to an internal combustion engine of the current consumer device provided with a blower by means of an air infeed channel having a suction opening facing in the direction of travel. Such air current is then removable as heated air from the cooling casing surrounding the engine through the floor of the current generator unit which is extensively open at the region of the engine and by means of at least one opening provided in the floor of the receiving compartment. The other cooling air current entering by way of a suction opening facing such direction of travel can be withdrawn by at least one blower arranged at a side opposite the rear wall of the current generator unit, through a diffuser equipped with a radial fan. This cooling air current is deliverable by the radial fan to an inner compartment of the current generator unit and is removable as heated air through the extensively open rear wall.
