Specific embodiment
Embodiment one:
Referring to Fig.1, a kind of diesel generator with low noise group, including what is be made of fuel engines 1, generator 2 and fuel tank 3 Main body, the Packed sound proofing enclosure 11 of the outer cup of main body, the lower part of main body is by passing through the connecting column 6 of sound proofing enclosure 11 under The support frame 7 of side connects, and the bottom of support frame 7 has stabilizer blade 8, and the both ends of support frame 7 have handle 10, fuel engines 1 Exhaust outlet 4 passes through exhaust pipe(It is not shown)The outside for leading to sound proofing enclosure 11 is equipped with hush pipe on exhaust pipe(Do not show Out), the lid 5 of fuel tank 3 is located at the outside of sound proofing enclosure 11, the cable hole passed through for cable is provided on sound proofing enclosure 11 12, it is provided with thermally conductive sheet 13 on the shell of fuel engines 1, the outside of sound proofing enclosure 11 is provided with cooling fin 15, it is thermally conductive Heat conducting pipe 14 is connected between piece 13 and cooling fin 15, heat conducting pipe 14 passes through sound proofing enclosure 11.
Referring to Fig. 2, sound proofing enclosure 11 is composite construction, and ecto-entad successively includes coat of metal 1101, mineral wool Layer 1102 and felt layers 1103, this composite construction have good absorbing sound and lowering noise effect.
During the work time, the diesel oil in fuel tank 3 is transported in fuel engines 1 generating set, fuel engines 1 Continuous running drives generator 2 to rotate, to realize power generation.Due to the Packed sound proofing enclosure 11 of the outer cup of generating set, Sound proofing enclosure 11 has the effect of sound insulation, can absorb the most of noise generated in power generation process, and a small amount of noise can only be made logical It crosses, to significantly reduce the noise that generating set takes in environment, realizes low noise operation.
The heat that the work of fuel engines 1 generates is conducted on cooling fin 15, is distributed by cooling fin 15 into air, is protected Demonstrate,proving fuel engines 1 is not in the excessively high situation of temperature in closed environment.
In the present embodiment, cooling fin 15 is vertically fixed on the side of sound proofing enclosure 11, under cooling fin 15 Side is provided with fan 17, and fan 17 and support frame 7 are fixed, and fan 17 directly takes electricity from generator 2.
Since cooling fin 15 can heat surrounding air, according to the principle that hot-air rises, cooling fin 15 is set vertically The air flows upwards for being conducive to be heated are equipped with, thus help to flow up cold air from the lower part of cooling fin 15, thus Make cooling fin 15 that there is good heat dissipation effect.
On this basis, fan 17 is dried from the bottom up, accelerates the circulation of 15 surrounding air of cooling fin, to be substantially improved The heat dissipation effect of cooling fin 15.
