PURPOSE:To reduce the dimension of a ventilating fan by installing the ventilating fan at the position over the heat generation part of a gas turbine on the edge part on the counter air inlet side of a cover member which surrounds the gas turbine and a working machine. CONSTITUTION:An air inlet 11 is formed at one edge 4a of a cover member 4 which surrounds a gas turbine 2 and the working machine 3 such as generator, and communicates to a unit accommodation chamber 10 through communication ports 31 and 33. An oil cooler 5 is installed at a proper position of the communication port 33 so as to cross air stream, and a ventilating fan 6 is installed on the other side 4b of the cover member 4 and at the position over the heat generating part such as the combustor 22 and the exhaust cylinder 23 of the gas turbine 2. Therefore, the temperature rise of the ventilating wind in the cover member 4 by the heat generated in the heat generation part can be suppressed, and the dimension of the ventilating fan can be reduced. |
