Embodiment Construction
[0020] Special cooling method of the present invention, see figure 1 , the interior of the generator case is cooled by two mutually independent cooling winds, one of which contains the high heat part of the engine through the suction cooling wind cover 10, upper wind deflector 14 and lower wind deflector 15 of the engine group, and is sucked in by the suction cooling fan The cooling air cools the high heat part of the engine, and then discharges to the upper cavity of the muffler 21 to cool the muffler 21, and then discharges through the hot air isolation cavity on the maintenance door assembly 26 on the generator case, which is the air duct E; The cooling air drawn in by the magneto fan 20 cools the magneto 3, the lower part of the exhaust pipe, and the lower part of the muffler 21, and then is discharged through the hot air isolation chamber on the maintenance door assembly 26 on the generator case. Road F. The muffler 21 is installed inside the cavity formed after the magn...

The invention provides a special cooling method of a generator, which can ensure that the overheating parts of an engine can be fully cooled; and the machine can be made into small volume, thus reducing production and manufacturing cost; the invention also provides a sealed gasoline generating set adopting the method. The special cooling method of the generator is characterized in that: the interior of the case of the generator is cooled by two mutually independent draughts of cooling air, wherein one draught encloses the overheating parts of the engine through a cooling air suction guard, an upper air deflector and a lower air deflector of an engine unit, cooling air inhaled by a cooling air suction fan is used for cooling the overheating parts of the engine and then is discharged to a cavity above a muffler to cool the muffler, and is finally discharged from a hot air separating cavity on an upper maintenance door assembly of the case of the generator, while the other draught cools a magnetor, the lower part of an exhaust pipe, the lower part of the muffler in virtue of the cooling air inhaled by a fan of the magnetor and then is discharged from the hot air separating cavity on the upper maintenance door assembly of the case of the generator.
Description
(1) Technical field [0001] The invention relates to a special cooling method for generators, and also relates to a closed gasoline generator set using the method. (2) Background technology [0002] There are three types of configurations in the existing generator sets. One is the open-frame configuration, which can meet the heat dissipation requirements of the generator to the greatest extent. The manufacturing cost is low, but it cannot meet the requirements of environmental pollution indicators; the second is the closed configuration, namely The functional accessories of the generator set are placed in a closed cabinet, so that through the complex air duct system, the heat dissipation requirements of the generator can be met, and it can also meet people's requirements for environmental protection and aesthetics, but the manufacturing cost is high and the production process is complicated. , not suitable for mass production; third, an independent ventilation and cooling sys...
