る。2. Description of the Related Art A conventional example will be described with reference to FIG. FIG. 3 is a diagram of a cooling and ventilation structure of a conventional engine generator. In the figure, the entire device is wrapped in an enclosure, the outside air is introduced from a suction hole on the driven machine side by a discharge fan provided in front of the engine and driven by the engine itself, and a part is used for combustion of the engine,
Exhaust gas from the engine is discharged from the exhaust hole to the outside of the enclosure through a muffler outside the enclosure. Most of the remaining air absorbs the heat radiation of the generator, which is the driven machine, and the engine to raise the temperature, and then further absorbs heat from the engine cooling water heat radiation radiator in front of the engine and is released to the atmosphere. The intake hole and the exhaust hole for the outside air communicate with the engine and the driven machine, which are noise sources.

よって昇温されない外気を使用したい。(1) Miniaturization of radiator and reduction of cooling air volume. In the conventional example, the air has already taken up heat from the engine and the driven machine before it enters the radiator, and the temperature has risen. Increases are required alone or in combination. Therefore, it is desirable to use outside air that is not heated by the engine or driven machine as the radiator cooling air.

ンクロージャ製造コスト低下も図れる。(2) Reduction of noise leakage from the cooling air intake and exhaust holes. The radiator cooling air intake / exhaust holes are connected to the noise source engine and driven machine, and noise leaks out significantly, so it is desirable to isolate the cooling air passage from the noise source. The intake and exhaust passages for the radiator cooling air use a small amount of cooling air by direct use of low-temperature outside air, and the discharge fan has a lower rotation speed, which in turn reduces the noise of the cubicle, and the cooling air volume for the engine and driven machine is radiator cooling. Since the amount of intake air is smaller than the amount of air used, the opening for intake and discharge is small, and noise can be easily prevented, so that the manufacturing cost of the enclosure can be reduced.

構造を提供することにある。The object of the present invention is to solve the above problems and prevent noise in the enclosure housing the engine and the driven machine from leaking out of the enclosure from the air passage, and the cooling air from the radiator for cooling water is used to cool the engine and the driven machine. An object of the present invention is to provide an enclosure soundproof cooling ventilation structure that can be separated from room cooling air to improve cooling efficiency.

いる。A soundproof cooling and ventilation structure for an enclosure of the present invention is an enclosure equipped with a radiator-cooled engine in which a radiator is provided in front of the engine and a discharge fan for blowing the cooling air for the radiator is driven by the engine. A soundproof partition 3 for partitioning the radiator / discharge fan installation section 15 from the engine / driven machine installation section 16, and a structure 13 for separating and ventilating the cooling air to both installation sections.
It is characterized by having a soundproof cooling and ventilation structure of an enclosure having 5, 6, 9, 2, 8, and 12.

The radiator cooling air discharge fan sucks the outside air directly from the outside air introducing duct 13 and sends it to the radiator to improve the cooling efficiency.
