Claims

[Scope of utility model registration request]

A vertical shaft engine 2 is installed inside a cover 1 that is open on the bottom surface.
A generator 3 disposed above the vertical axis engine 2 and directly connected to the vertical axis engine 2, and a cooling fan 4 fixed to the upper end of the rotating shaft 10 of the generator 3 are arranged. and covering the side surface of the generator 3 with a wind guide case 13 across the main cooling air passage 12;
A fan room 21 for storing the cooling fan 4 is formed in the cover 1, and the main cooling air passage 12 is communicated with the fan room 21 through a main air intake port 27, and the main cooling air passage 12 is communicated with the fan room 21 through an upper air intake port 28. By connecting the air guide case 13 inside the cover 1 and the upper part of the space outside the fan room 21 and driving the cooling fan 4, air is sucked into the fan room 21 through the main cooling air path 12 and the main air intake port 27. The vertical shaft engine 2 and the generator 3 are cooled with cooling air, while the air outside the air guide case 13 inside the cover 1 and the fan room 21 is sucked into the fan room 21 through the upper air intake port 28. A cooling device for an air-cooled engine generator, characterized by the following.
