Abstract
The invention relates to a frequency converter housing of a gasoline engine generator, a housing main body is an open rectangular box, a ventilation hole is arranged on the housing, a part of ventilation hole is positioned at the bottom of the rectangular box, and the other part of the ventilation hole is higher than the rectangular box, the internal surface of one lateral wall of the rectangularbox in the width direction is depressed to form an air guide trough, and the lateral wall which is in the length direction of the rectangular box and divides the ventilation hole into two parts is provided with a strip-shaped ventilation port. By adopting the frequency converter housing, cold air can cool the gasoline engine generator regularly through a frequency converter, and meanwhile, cold air can be conveniently and smoothly guided into a generator fixed rotor, an engine and other components, thereby improving the ventilation and heat dissipation effect of the whole gasoline engine generator.
Description
Technical field
The present invention relates to a kind of gasoline engine generator parts, relate to frequency converter housing of gasoline engine generator concretely.
Background technology
For attractive in appearance and reduce noise, some gasoline engine generator has adopted the closed shell structure, only the bottom of shell and wherein two sides be provided with the ventilating opening of venetian blind type.In the generator housing except that flywheel fan cover and kuppe that cold and hot differentiation dividing plate and petrol engine itself carry, other position of generator is not provided with the parts that wind is led in order specially, therefore its result of ventilating heat dissipation is poor, particularly installed the gasoline engine generator of frequency converter additional, work under suitable ambient temperature owing to must guarantee each element of frequency converter, so ventilation and heat is had higher requirement.
The air-cooled process of existing closure formula frequency conversion gasoline engine generator is: the cold wind that enters from housing side louvre ventilation mouth, at first be cooled to frequency converter, but because the space around the frequency converter is big, cold wind passes through frequency converter fast, dispersedly, and frequency converter is not adequately cooled; Cold wind is from the flywheel fan of the centre pilot engine of rotor then, owing to can cause certain resistance to wind during the rotor running, and the motor stator end directly links to each other with the flywheel fan cover, causes a large amount of wind successfully not import to the hot-zone through the flywheel fan cover and removes to cool off the crankcase housing.These wind are circuitous pacing up and down in the cold-zone, hindered air inlet air intake and air outlet air draft successfully swimmingly, makes the temperature of the temperature of whole gasoline engine generator frequency converter inductance and engine motor oil all higher, influenced the normal performance of machine performance.
Summary of the invention
In view of this, the invention provides a kind of frequency converter housing of gasoline engine generator, make cold wind to cool off it by frequency converter regularly, the parts such as generator stator-rotator and engine of also being convenient to simultaneously cold wind led smoothly improve the result of ventilating heat dissipation of whole gasoline engine generator.
For achieving the above object, the invention provides a kind of frequency converter housing of gasoline engine generator, this outer cover main body is uncovered rectangular box, and outer cover is provided with ventilation hole, and the wherein part of ventilation hole is positioned at the rectangular box bottom, and another part is then above rectangular box.
Frequency converter is placed in the uncovered rectangular box, the one side of frequency converter band aluminium radiator fin is uncovered towards rectangular box, part cold wind blows to the one side of frequency converter band aluminium radiator fin, and through around the frequency converter and the gap between the rectangular box sidewall frequency converter is cooled off, the ventilation hole that arrives the rectangular box bottom then continues the guiding generator stator-rotator; Another cold wind is directly by that part of ventilation hole guiding generator stator-rotator above rectangular box.As seen, after frequency converter housing of gasoline engine generator of the present invention has been arranged, not only frequency converter obtains very sufficient cooling, and parts such as the easier guiding generator stator-rotator of cold wind, engine flywheel fan guard and engine flow guiding cover, make each parts of the hot and cold district of whole gasoline engine generator all obtain good cooling, improved the result of ventilating heat dissipation of whole gasoline engine generator.
Further, a wherein side wall inner surfaces of above-mentioned rectangular box Width is through being recessed to form wind guide tank, behind the assembling frequency converter, the position of frequency converter inductance is just corresponding to this wind guide tank, and from then on the cold wind of wind guide tank process can cool off especially to the relative bigger inductance of caloric value.
Further, above-mentioned rectangular box length direction is separated into ventilation hole the bar shaped ventilating opening that two-part that sidewall is provided with grid type.Directly pass through by the bar shaped ventilating opening of above-mentioned grid type the frequency converter side to be cooled off above the wind of that part of ventilation hole guiding generator stator-rotator of rectangular box.
After adopting the present invention, cold wind can cool off it by frequency converter regularly, and the parts such as generator stator-rotator and engine of also being convenient to simultaneously cold wind successfully led have improved the result of ventilating heat dissipation of whole gasoline engine generator.
