US Patent 10150552 Forced flow water circulation cooling for barges

The disclosure relates to an open-loop cooling system installed on a refrigerated barge for removing heat from an external heat exchanger in communication with a closed-loop internal cooling system. The system includes an open loop with a pump drawing water from the environment and forcing the water across the outer surface of the heat exchanger to augment existing heat removal due to contact with and flow of water across the heat exchanger due to the motion of the barge. Water is forced across the side faces and inner faces of the cooler to increase heat transfer from the barge closed-loop cooling system to the water environment.
