Abstract: In a plant for cooling heated goods, for instance cast iron, the goods is transported in a predetermined direction through one or several cooling sections (1,2,3). Through the tunnels a closed piping system (4) transports a fluid in a direction which is opposite to the transportation direction of the goods. The piping system also comprises at least one heat exchanger in which at least part of the heat from the goods is transferred to the fluid under the intermediary of a separate cooling medium which is brought in direct contact with the goods. A considerable part of the heat being emitted from the goods can thereby be transferred to the fluid and the heat energy thus taken care of can either be converted to electric energy or be directly used for heating purposes.
