Two-channel air-cooled small gasoline generator

Abstract

A two-channel air-cooled small gasoline generator, comprising a case (1), an engine assembly (2), a silencer (3) and a magneto assembly (4) with a fan, wherein the engine assembly (2), the silencer (3) and the magneto assembly (4) are arranged in the case. The gasoline generator further comprises: a first air guiding hood (21), arranged on the engine assembly (2) in a coating mode; an air duct (32), one end of the air duct being connected to the first air guiding hood (21), and the other opposite end of the air duct being communicated with the outside; a second air guiding hood (31), arranged on the silencer (3) in a coating mode and provided with an air outlet (311) communicated with the outside; and a third air guiding hood (41), arranged on the magneto assembly (4) in a coating mode and further communicated with the second air guiding hood (31). In the generator, the engine is cooled at high efficiency, thermal power attenuation of the engine is effectively reduced, and the output of the magneto is efficient; accordingly, high-efficiency operation of the generator is guaranteed, and a good noise isolation effect is achieved with the sealed air duct.

Description

technical field [0001] The invention relates to a gasoline generator, in particular to a dual-channel air-cooled small gasoline generator. Background technique [0002] Forced air-cooled generator sets require enough cold air to cool the high-heating parts of the generator set, such as the engine cylinder head, crankcase, permanent magnet generator and muffler, etc., and at the same time meet the increasing environmental protection requirements, so it is required Overall, it has the characteristics of beautiful appearance, less pollution, low energy consumption, and high space utilization rate. [0003] In the overall configuration of the existing small generator sets, three configuration methods are mainly adopted: 1. Open-frame configuration, which can meet the heat dissipation requirements of the generator set to the greatest extent, and the manufacturing cost is low, but it cannot meet the requirements of low noise and environmental pollution indicators Second, the clos...

Problems solved by technology

This kind of cooling structure has few joint surfaces, and the cooling and ventilation cavity formed is easier to ensure the sealing requirements, but it cannot guarantee sufficient cooling of the places where the engine generates a lot of heat, such as around the engine cylinder, exhaust pipe, and oil shell at the bottom of the engine. , poor cooling effect
