The diesel engine of the diesel generator set generates a large amount of heat in the process of driving the generator to generate electricity, the higher the generating power of the diesel generator is, the more the generated heat is, once the heat of the diesel generator set can not be dissipated to the outside in time, the diesel generator is easy to break down due to overheating of the engine body, and further the electric energy can not be continuously output. Therefore, the air circulation is ensured, and the heat generated in the power generation process of the diesel generator is taken away by the air flow, which is one of important means for ensuring the normal working temperature of the diesel generator.

Specifically, the conventional diesel generator set includes a supporting base, a generator body, and a fan, wherein the power generation main body comprises a heat dissipation channel, one end of the heat dissipation channel is communicated with the outside, the fan is provided with an air outlet channel, the power generation main body is arranged above the supporting base, the power generation main body generates electric energy in the operation process, to supply electric power to mechanical equipment attached to the power generating main body, the fan being held at one end of the power generating main body, the air outlet channel of the fan is communicated with the heat dissipation channel, the fan is driven to rotate, negative pressure is formed at one end of the power generation main body, so that outside air passes through the heat dissipation channel of the power generation main body and then leaves the diesel generator set from the air outlet channel of the fan, and heat generated by the power generation main body is taken away.

However, in the power generation process of the conventional diesel generator set, the conventional diesel generator set usually has high running noise, and noise generated by the power generation main body is transmitted to the outside from the heat dissipation channel, so that high noise pollution is caused, and the working environment of a user is affected. In order to reduce noise, the conventional diesel generator set further includes a housing having a receiving cavity, the housing being mounted on the support base, the power generating main body and the fan being received in the receiving cavity of the housing, and noise generated by the power generating main body being blocked by the housing from being transmitted to the outside. However, in this way, the circulation of air is obstructed, and the heat generated by the power generating main body is also gathered in the accommodating cavity of the shell, so that the heat dissipation efficiency of the diesel generator is reduced, and the power generation power of the diesel generator set is affected. Some diesel generating set on the market through set up a plurality of through-holes in the casing for accelerate the circulation of air, though improved diesel generator's radiating efficiency, it is difficult to reduce the noise that diesel generating set produced in the operation process.

Therefore, it is urgently needed to improve the structure of the generator set so as to reduce noise pollution generated by the generator set while ensuring the heat dissipation requirement of the generator set.
