A duct type cooling frequency conversion unit and its layout

Abstract

The invention relates to an air duct type cooling frequency conversion unit and its layout method. The layout mode of the air duct type cooling frequency conversion unit includes a first air duct and a second air duct; the first air duct flows in from the first air inlet The generator, after cooling the generator, enters the engine, then cools the engine, enters the muffler after cooling the engine, and discharges out after cooling the muffler; the second air inlet channel flows in from the second air inlet, passes through the cooling inverter After that, it merges with the first air duct and flows out of the muffler. Its advantages are as follows: the air duct cooling frequency conversion unit and its layout mode of the present invention, through the structural improvement of the whole machine and the layout of the air duct cooling, make the whole machine small in size, light in weight and good in cooling effect.

Description

technical field

[0001] The invention relates to the technical field of frequency conversion units, in particular to an air duct cooling frequency conversion unit and its layout. Background technique

[0002] With the rapid development of the economy and the improvement of people's living standards; as a kind of emergency power supply - variable frequency generators are becoming more and more popular. However, there are following defects and deficiencies in the frequency conversion generator in the prior art:

[0003] First of all, regarding the structure, in the frequency conversion generator set in the prior art, the generator is installed below the muffler. The inverter is installed at the outer end. In order to ensure the stability of the engine speed and achieve the purpose of controlling the smooth operation of the engine, the flywheel is made of cast iron in a solid disc shape, which makes the size of the flywheel larger, the size of the whole machine is larger, and ...
