ABSTRACT:
A cooling arrangement is provided for an electric generator of an underwater power plant contained in a body wherein a coolant is circulated for cooling the generator. The cooling arrangement includes a cowl that covers the end-face of the generator and forms a portion of the body. The outer surface of the cowl is exposed to the turbine water and the inner surface of the cowl defines a path for conducting the coolant therealong for recooling the coolant. A plurality of cooling fins are provided and each of the fins has two end-portions bent toward each other to give the fin a hook-like configuration. Each fin is fixedly mounted to the inner surface of the cowl at one of the end-portions thereof. The fins are short relative to the length of the path.
