Problems solved by technology

At this time, the cooling effect of the muffler is extremely poor. The muffler itself is a heat source plus the resistance of the muffler. The high-temperature gas may also cause circulation.
Hot air may be stored in the generator set for a long time, and may be absorbed by the carburetor air intake at this time, causing the intake air temperature to be too high. High intake air temperature will cause the gasoline in the carburetor to vaporize before it is vaporized , causing engine air resistance, and even affecting the normal operation of the engine

Abstract

The invention discloses a ventilated cooling device of a digital generating set. The ventilated cooling device comprises an engine side cover, a silencer arranged at the outer side of the engine side cover, a crankshaft, and an impeller arranged on the crankshaft and positioned between the engine side cover and the silencer, wherein one end of the crankshaft extends out of the engine side cover. The ventilated cooling device is characterized in that: a volute air guide device is also arranged between the engine side cover and the silencer, the volute air guide device is provided with a main air inlet and a main air outlet along the axial direction of the crankshaft, meanwhile, a volute cavity is formed in the volute air guide device, and the impeller is positioned in the volute cavity. The volute air guide device is arranged between the engine side cover and the silencer, the volute air guide device is combined with the impeller therein to form a 'turbo charging cooling device' together, and the 'turbo charging cooling device' can eliminate hot air circulation in the digital generating set and enhance the cooling effect.

Description

technical field [0001] The invention relates to a ventilation cooling device for a digital generator set. Background technique [0002] The well-known silent digital generator sets adopt a fully enclosed design. The engine and generator are surrounded by a casing, and a thick sound-absorbing sponge is pasted on the inner surface of the casing, so that the heat inside the engine is difficult to dissipate. The generator set in this state requires very good heat dissipation conditions, otherwise it will cause the engine to overheat, and the power will drop in a short time. [0003] 1. At present, most silent digital generator sets on the market generally use super-large mufflers to obtain better noise reduction effects. The side cover of the engine in this generator set will be occupied by the muffler, although the cylinder head and the muffler guard plate Creates an air duct, but only cools the side of the muffler near the cylinder head. In addition, due to the compact struc...
