Abstract
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 at the air inlets and large 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 large surface heat exchangers (3). At least one pre-heating heat exchanger (20) is arranged in the air space (29) of each sector of the large surface heat exchangers (3), and the pre-heating heat exchangers (20) are in parallel connection with the large surface heat exchangers (3) of each sector.
