Closed cooling tower with novel structure

The utility model relates to the technical field of cooling, in particular to a closed cooling tower with a novel structure, which comprises a cooling box, two groups of heat exchangers which are oppositely distributed are arranged in the cooling box, a detection channel is formed between the two groups of heat exchangers, an air bellow is arranged above the two groups of heat exchangers, and a fan is arranged above the air bellow. And internal air flow of the heat exchanger enters the air bellow through the detection channel and is exhausted from the fan. The fan is arranged above the heat exchangers, so that the type selection of the fan is not limited, a large-air-volume fan can be selected, the heat exchangers on the two sides can be widened, the heat exchange area is increased, the redundant space of a maintenance channel is reduced, space waste is avoided, the air bellow is arranged between the heat exchangers and the fan, a certain space is provided, air draft of the fan is facilitated, and the heat ex
