Problems solved by technology
[0002] At present, the fan of the traditional silent diesel generator set directly blows the liquid-cooled radiator to cool down. The air enters the engine room through the vent first to dissipate heat from the generator and cool the heat radiation of the engine. The cooling effect of the high wind temperature is not good, which affects the power of the generator set; the large area of the air intake and exhaust passage makes the engine noise easy to spread, the noise of the generator set is high, and the mute effect of the generator set is poor
[0003] In view of the disadvantages of high noise and poor radiator cooling effect in the existing diesel generator set, it is necessary to carry out technical improvement on the existing diesel generator set

The invention discloses a partition heat dissipation and noise reduction structure of an ultra-quiet diesel generator set, which comprises a double-fan fixed shaft arranged between a diesel engine and a radiator, a large engine fan and a centrifugal fan respectively arranged on the double-fan fixed shaft, And the centrifugal fan is located between the large engine fan and the diesel engine, the exhaust port of the large engine fan faces the radiator, the air suction port of the centrifugal fan is close to the air outlet end of the diesel engine, and is between the air outlet end of the diesel engine and the centrifugal fan. There is a middle partition between them, and the middle partition is provided with an air inlet hole for introducing the hot air from one side of the diesel engine to the side of the suction port of the centrifugal fan. The cover is provided with an air guiding channel separated from the large fan of the engine. The invention improves the cooling effect of the radiator of the diesel generating set and reduces the noise of the diesel generating set.
Description
technical field [0001] The invention relates to the technical field of diesel generator sets, in particular to a partition heat dissipation and noise reduction structure of an ultra-quiet diesel generator set. Background technique [0002] At present, the fan of the traditional silent diesel generator set directly blows the liquid-cooled radiator to cool down. The air enters the engine room through the vent first to dissipate heat from the generator and cool the heat radiation of the engine. After cooling, it ventilates and cools the radiator. The cooling effect of the high wind temperature is not good, which affects the power of the generator set; the large area of the air intake and exhaust passage makes the engine noise easy to diffuse, the noise of the generator set is high, and the mute effect of the generator set is poor. [0003] In view of the disadvantages of high noise and poor cooling effect of the radiator in the existing diesel generating set, it is necessary ...
