In a cooling apparatus operated by ambient air and an agent to be cooled which can have solid state at atmospherical temperatures, a housing such as a cooling tower (100) with air inlets and air closure means (11) at the air inlets and great surface heat exchangers (3) arranged within the cooling tower (100) at its air inlets and divided into groups or sectors being in parallel connection are provided, with which the agent is cooled by the air streaming through the great surface heat exchangers (3). According to the invention, at least one pre-heating heat exchanger (20) is arranged in the air space (29) of each sector of the great surface heat exchangers (3), and the pre-heating heat exchangers (20) are in parallel connection with the great surface heat exchangers (3) of each sector. |
