  • Patent number: 4579090
    Abstract: A cooling apparatus for a radiator through which a coolant of the drive unit flows, and to which cooling air is supplied. The radiator is disposed in a separate compartment of a vehicle, especially an armored vehicle, and is disposed above a cooling air fan. Openings in the roof and back end of the vehicle for supplying air to, and withdrawing air from, the cooling air fan are provided with gratings. A spraying arrangement is integrated into the separate compartment. This spraying arrangement includes a tube system which extends over the radiator and is spaced therefrom. The tube system is provided with jets for uniformly distributing a cooling liquid. The tube system communicates with a primary supply line, which is provided with a feed pump, a two-way valve, and an intake orifice which is disposed just above the bottom of the vehicle. A cooling liquid reservoir is mounted in the vehicle and is connected via a secondary supply line with the two-way valve.
