Background technology
Small-sized digital electricity generating group is made up of internal combustion engine, permanent magnet generator, inverter controller.Since the nineties in last century, Japanese honda, Yamaha were released small gasoline permanent magnet generator unit, the permanent magnet generator machine technology had obtained paying close attention to widely, and the technology report about the permanent magnet generator unit has been arranged a lot.With regard at present disclosed technology and product, all be to have cancelled flywheel, magneto is installed in position corresponding to excitation generator group flywheel, and the motor in the logarithmic code generating set, the inverter controller cooling processing of dispelling the heat, and the heat radiation cooling all is the mode that adopts fan, fan is installed in the generator amature outside, drives fan by generator amature and rotate.At present, inverter controller is for the cooling of dispelling the heat, common way is to place inverter controller within the fan housing and be positioned at the fan front end, and air when fan rotates that fan housing is outer is inhaled into, and air is realized heat radiation and cooling to inverter controller through inverter controller in suction process.There is tangible deficiency in this mode, because inverter controller is positioned at the fan front end, is in the air intake direction, can increase the air intake resistance, for guaranteeing cooling effect, fan blade need be increased a lot, can increase the power that fan consumes.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides a kind of digital permanent magnet generator unit that can not increase windage when solving generating set motor and inverter heat radiation cooling problem again.
The technical solution of the utility model is achieved in that a kind of digital permanent magnet generator unit, comprise internal combustion engine, bent axle, generator unit stator, generator amature, hand pulling starter, cooling fan, fan housing, inverter controller and muffler, generator unit stator is fixedly mounted on the internal combustion (IC) engine airframe and is positioned at generator amature, cooling fan and generator amature are fixedly mounted on the bent axle, fan housing is installed on the internal combustion engine casing, its front is provided with air inlet, hand pulling starter, cooling fan and generator amature are positioned at fan housing, it is characterized in that: described inverter controller is positioned at the outside side of fan housing, and the position that fan housing is corresponding with inverter controller has some heat transmission air guide holes.
Further, described fan housing is two, be respectively oily machine fan housing and generator fan housing, cooling fan is two centrifugal fans that the blade rotation direction is opposite, one of them cooling fan is installed in away from bent axle one end of generator amature and is positioned at the generator fan housing, inverter controller and muffler are positioned at the outside left and right sides of generator fan housing, the position that the generator fan housing is corresponding with muffler has some heat transmission air guide holes, and another cooling fan is installed in the generator amature outside and is positioned at oily machine fan housing jointly with hand pulling starter and generator amature.
The utility model inverter controller is positioned at the fan housing exterior lateral sides, the air-out that utilizes fan is to its heat radiation cooling, avoided being positioned at the air intake resistance that the fan front end produces, therefore this structure had both solved the heat radiation cooling problem of generating set motor and inverter, can not increase windage again, so the heat radiation cooling is reliable.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Embodiment 1: referring to Fig. 1, Fig. 2, from the figure as can be seen, the digital permanent magnet generator unit of present embodiment mainly comprises generating set shell, panel, bent axle 7, oily machine fan housing 1, hand pulling starter 2, internal combustion engine 6, generator unit stator 5, generator amature 4, cooling fan 3, inverter controller 9 and muffler 8.Generator unit stator 5 is fixedly mounted on internal combustion engine 6 bodies, and I. C. engine crankshaft 7 passes from generator unit stator 5 mesopores, and bent axle 7 one ends are installed with generator amature 4, and generator unit stator 5 is positioned at generator amature 4.Cooling fan 3 is for centrifugal fan and be positioned at generator amature 4 outsides and generator amature 4 is fixedly installed togather.Oil machine fan housing 1 is installed on the internal combustion engine casing, and its front is provided with air inlet 10, and hand pulling starter 2, cooling fan 3 and generator amature 4 are positioned at oily machine fan housing 1.Be provided with air duct in I. C. engine crankshaft casing, the cylinder head.Inverter controller 9 is positioned at oily machine fan housing 1 an outside side, and oily machine fan housing 1 and inverter controller 9 corresponding positions have some heat transmission air guide holes 12, and blowing out cooling air thus is inverter controller 9 heat radiations.Muffler 8 be positioned at oily machine fan housing 1 back to internal combustion engine 6 body opposite sides.
Embodiment 2: referring to Fig. 3, Fig. 4, by contrasting as can be seen with Fig. 1 and Fig. 2, the difference of present embodiment and embodiment 1 is, fan housing is two, except oily machine fan housing 1, also has generator fan housing 11, cooling fan also is that two and blade rotation direction are opposite, and promptly embodiment 2 has increased generator fan housing 11 and a cooling fan on the basis of embodiment 1.The mounting means of oil machine fan housing 1, hand pulling starter 2, one of them cooling fan 3 (being equivalent to original cooling fan), generator amature 4, generator unit stator 5 and bent axle 7 is identical with embodiment 1, does not give unnecessary details at this.
