Problems solved by technology

The patent number is 99100615.1, and the patent name is a portable generator. This patent discloses a generator, which adopts a single cooling air duct, and the cooling air is blown by a separate cooling fan to cool the generator, motor and muffler in sequence. The cooling effect is Better; In addition, the patent number is 03121181.X, and the patent name is an engine generator. This patent discloses a kind of generator, which adopts double cooling air passages, wherein one air passage is sequentially connected to the cylinder head of the controller, the engine, and the muffler. The cooling is carried out sequentially, and the other air duct cools the engine crankcase and the generator in turn. In this scheme, because the heat of the engine crankcase is high during the working process, after the cooling air passes through the crankcase, the cooling air has become Very hot, not conducive to cooling the rear generator body, the effect is not good

Abstract

A generator with double cooling duct consists of shell, inverter, power generating body and silencer. It is featured as setting power generating body in front or back of cooling fan and connecting it with the first cooling fan coaxially, setting the first and the second cooling fans separately at two ends of crankshaft of engine to let two said fans be driven by engine for forming the first and the second air ducts in said shell.

Description

technical field [0001] The invention relates to a generator, in particular to a generator set with dual cooling air ducts in which an engine and a generator are arranged in a housing. Background technique [0002] Usually, when the generator is working, the temperature inside the body is relatively high, especially for small generators, due to the limited space inside the body, how to quickly get rid of It is a problem that must be considered to discharge the heat flow inside the machine body, effectively cool the engine and generator body, and maintain good heat dissipation of the generator. The patent number is 99100615.1, and the patent name is a portable generator. This patent discloses a generator, which adopts a single cooling air duct, and the cooling air is blown by a separate cooling fan to cool the generator, motor and muffler in sequence. The cooling effect is Better; In addition, the patent number is 03121181.X, and the patent name is an engine generator. This p...
