The working principle of the low-noise generator set is further described as follows:
as shown in fig. 2 and 3, a cooling radiator, which is a component for cooling the engine, and a muffler are provided in the cooling and heat dissipating compartment. The water inlet and outlet pipes of the cooling radiator are connected with the water inlet and outlet pipe of the engine through a pipeline, the cooling radiator is an electronic fan type radiator, when the engine runs, the engine starts to work with a water pump, a water circulation system runs, hot water from the engine enters the engine after being cooled by the cooling radiator, and the engine is guaranteed to work at a proper temperature. The cold air circulation of the cooling and heat dissipating cabin is independent, that is, as shown in fig. 4, B1 and B3 are air inlets of the cabin, B2 is an air outlet of the cabin, and the cooling air of the cooling radiator circulates independently in the cabin to form cooling for a water tank in the cooling radiator.
As shown in fig. 2, the engine compartment, in which the engine and the necessary pipes (water pipes and muffler pipes) are installed, is characterized by complete sealing and no air circulation inside, so that the noise of the engine can be maximally reduced through the case. In the cabin, a key part of the engine is water circulation cooling, namely a water-cooling exhaust manifold 5-2 in fig. 3, and continuous tests show that the feasibility of the scheme can be ensured only if the exhaust manifold is of a water-cooling type, because the exhaust manifold of the engine is a high-heating part, if a natural air-cooling type is adopted, the temperature in the cabin is continuously increased, and the whole engine is stopped at a high temperature. The water-cooling type exhaust manifold is arranged, tests show that the water-cooling type exhaust manifold has a good effect, the air temperature of the cabin body can be kept constant at 58-67 ℃, the air temperature completely meets the working temperature of each part, and good running of an engine can be guaranteed.
As shown in fig. 2, the generator exhaust compartment 6 has two functions, one is the exhaust of the generator and the other is the air intake of the air filter of the engine. The cabin body separates the air inlet and the air outlet of the generator through the structural design, cools the hot air of the generator, and exhausts the hot air through air outlets A2 and A3 shown in figure 4.
As shown in fig. 2, the generator air intake compartment 7 has two functions, one is to set up a reasonable generator air intake channel to ensure the effective cooling of the generator, and the other is to set up a control system, as is well known, the generator control system is an electrical component, which generally cannot work in a high temperature environment, and the electrical control system is set up in the generator air intake compartment, and the air intake of the generator can cool the electrical component, so that the control system can work at a lower temperature.
Introduction fig. 3:
when the generator set runs, cooling air of the generator is sucked in by the generator 7-2 through the generator air inlet A1, the cooling air enters the generator exhaust cabin 6 after passing through the air duct cooling coil in the generator, part of the cooling air enters the air filter 6-2 of the engine, and the rest of the cooling air is exhausted from the generator exhaust outlets A2 and A3 through the air duct.
When the engine runs, cooling water passes through the engine cylinder sleeve to cool the engine, the water outlet of the engine is connected with the water inlet of the water-cooled exhaust manifold 5-2, hot water after cooling the exhaust manifold is connected with the water inlet of the cooling radiator through pipelines 5-4 and 4-3, and the cooling water passes through the pipelines; after the cooling radiator is cooled, the cooling radiator is connected with a water inlet of the engine through a pipeline 4-5, and therefore a water cooling circulation is formed.
It can be seen that in the mute box structure, the engine compartment 5 is equivalent to a sealed compartment (the sealed compartment has the largest isolation noise), and can isolate the noise to the greatest extent, so that the generator set has a good noise effect. In addition, the water-cooled exhaust manifold of the engine prevents the temperature of the cabin from continuously rising.
It can be seen that the four cabin bodies 4, 5, 6 and 7 are independent from each other and have a certain correlation to form a mute box body of the generator set, and the biggest bright point of the structure is that the cabin body 5 can be completely sealed.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
