side opening wind hood

Abstract

The invention relates to a universal generator part, in particular to a side opening air director of a universal generator. The side opening air director comprises an air director main body, wherein the middle part of the air director main body is protruded outwards to form a cylindrical space for accommodating a flywheel fan, a mesh enclosure is arranged in an outer port of the cylindrical space, the side edge of the air director main body is turned outwards and extends to provide with a bolt hole in the extension part, the air director main body is fixedly connected to a general engine main body through a bolt, a side air opening is formed in the side surface of the air director main body, the side air opening is in a rectangular shape, the side air opening is communicated to a generator heat radiating air duct through a cold air conduit, and the position of the side air opening is tangential to a rotary surface of the flywheel fan. By adopting the technical scheme, the side opening air director is simple in structure, good in silencer heat radiating effect, low in cost and capable of not influencing the portability of a diesel engine.

Description

technical field [0001] The invention relates to a general generator component, in particular to a wind guide cover with a side opening of the general generator. Background technique [0002] At present, the output power requirements of diesel-powered general machines are constantly increasing, and at the same time, various expansion measures have to be taken in order to meet the portable requirements. The results of these measures often cause the oil temperature of diesel-powered general machines to be too high and reduce reliability. To solve the heat dissipation problem of this type of engine, a finned plate-type air-cooled radiator will be installed at the flywheel windshield, and the flywheel fan will supply cold air to the fins of the body, which can obtain a very ideal cooling effect. In addition, the noise of diesel-powered general machines is generally large, and a muffler will be installed. The vertically installed baffle inside the muffler can block the propagation...

AI Technical Summary

Problems solved by technology

In addition, the noise of diesel-powered general machines is generally large, and a muffler will be installed. The vertically installed baffle inside the muffler can block the propagation of sound waves and allow airflow to pass through. However, due to the certain temperature of diesel-powered exhaust gas, the temperature of the muffler shell will The noise reduction effect is not good enough, the usual way is to use the wind from the outlet of the cooling air duct of the generator to dissipate heat for the muffler

Now with the implementation of diesel power expansion measures, the temperature of the muffler shell is higher, and the temperature of the outlet air of the generator cooling air duct is also higher, so the heat dissipation of the muffler shell cannot be well performed

However, if an additional air-cooling device is introduced, the portability of the diesel-powered general machine will inevitably be reduced. It can be seen that there are no good measures to solve the above contradictions.
