Abstract

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.

Dependent claims

In a cooling system for cooling a liquid coolant in an immersible motor vehicle, comprising

a chamber structure defining a chamber,
inlet means for admitting fluid to said chamber at one end thereof,
outlet means for delivering fluid from said chamber at the opposite end thereof,
a radiator disposed in said chamber between said ends thereof and comprising heat exchange surface means having heat exchange surfaces defining on one side a flow path for said liquid coolant and exposed on the other side to said chamber,
a fan, which is operable to cause air to flow from said inlet means through said chamber in contact with said other side of said heat exchange surface to said outlet means, wherein
said inlet and outlet means permit also a flow of water through said chamber in contact with said heat exchange surfaces on said other side,
the improvement residing in that
a partition is provided, which divides said chamber into first and second compartments and divides said heat exchange surfaces at least on said other side into first and second sections,
said inlet means comprise an air inlet communicating with said first compartment and a water inlet communicating with said second compartment,
said outlet means comprise an air outlet communicating with said first compartment and a water outlet communicating with said second compartment,
outlet valve means are provided for selectively opening and closing said air outlet,
said first and second compartments communicate with each other through a passage disposed between said air inlet and said radiator,
a selector valve is provided for selectively opening and closing said passage, and
said fan is disposed upstream of said passage.

a first closing means connected to said air outlet for closing said air outlet when said motor vehicle is immersed,
a water inlet connected to said second compartment, said water inlet operable to allow water to flow into said second compartment when said vehicle is immersed,
a water outlet connected to said second compartment for allowing water to flow out of said second compartment, and
a second closing means for selectively opening and closing said passage, said second closing means being closed and said second section being cooled by water when said vehicle is immersed.
