In a cooling system for floatable and/or submersible motor vehicles having a liquid-cooled engine the radiator (1) is accommodated in a chamber (2), which during land travel is flown through by air supplied by a fan (V) and which admits water when the vehicle is submerged or floating. In order to decrease the loss of buoyancy when the vehicle is floating or submerged and to reduce any lateral shifting of weight, the chamber (2) contains a partition (5), which divides the heat exchange surfaces of the radiator into two sections at least on the cold side. The air supply duct (6) opens into the preferably larger compartment (2a), which is disposed on one side of the partition and provided with flow passages (8), which lead to the outside and are adapted to be closed. The other compartment (2b) is preferably smaller and is adapted to be shut off from the compartment (2a) and is the only compartment which is floodable.

Cooling system for cooling a liquid coolant in an immersible motor

A longitudinal housing wall for an internal combustion engine is formed with an elongate channel defined by two confronting parallel surfaces. A rod extends in said channel over at least two-thirds of the length of said channel and is coupled to said wall so as to be resiliently movable relative to said wall and capable of absorbing energy of flexural vibration at a predetermined frequency from said wall.
