Abstract
To achieve the improvement of maintainability, simplification of structure, upon arranging a cooling fan on an outdoor side of a heat exchanger. To configure such that heat exchangers are arranged so as to face an openable/closable cover in a closed state, in a main accommodating chamber having an opening part which is opened or closed by the openable/closable cover; on the other hand, cooling fans are mounted in the operable/closable cover, and the cooling fans faces heat exchangers to supply cooling air in the closed state of the openable/closable cover; on the other hand, the cooling fans are separated from the heat exchangers in an open state of the openable/closable cover to allow the heat exchangers to be accessible from the opening part.

An arrangement structure of cooling fan configured such that, in a construction machine equipped with a heat exchanger arranged in an accommodating chamber having an opening part, an openable/closable cover for covering the opening part so as to be freely openable and closable, and a cooling fan for supplying cooling air to the heat exchanger, upon arranging the cooling fan on an outdoor side of the heat exchanger, the heat exchanger is arranged at a position facing the openable/closable cover in a closed state, and the cooling fan is mounted in the openable/closable cover, wherein in the closed state of the openable/closable cover, the cooling fan faces the heat exchanger to supply cooling air;
- on the other hand, in an open state of the openable/closable cover, the cooling fan mounted in the openable/closable cover is separated from the heat exchanger to allow the heat exchanger to be accessible from the opening part.
