An all-weather air-cooled diesel generator set

Abstract

The invention discloses an all-weather air-cooled diesel generating set. By the adoption of the all-weather air-cooled diesel generating set, demands for ventilation and heat dissipation of the unit can be met, leakage of noise can be effectively lowered, and external rainwater and sand wind can be effectively prevented from entering the unit. The all-weather air-cooled diesel generating set comprises a machine case, an oil tank, a control box, a generator and an air-cooled engine and further comprises an air inlet chamber, a flexibly-connected cylinder body, an exhaust air duct, a pair of auxiliary air inlet windows, an axial flow fan and a tower-shaped exhaust cover plate. The air inlet chamber is arranged at the rear end of the interior of the machine case. An air inlet window is formed in the rear side wall of the air inlet chamber. The two ends of the flexibly-connected cylinder body are communicated with the air inlet chamber and the cooling fan respectively. The exhaust air duct is connected between an exhaust outlet of an oil cooler and the top end of the machine case. The pair of auxiliary air inlet windows are oppositely arranged on the two side walls of the machine case and correspond to a cylinder block of the generator in position. The axial-flow fan is installed on the top of the interior of the machine case and corresponds to the cylinder block of the generator in position. The tower-shaped air exhaust cover plate comprises an annular baffle fixed to the top end of the machine case and a cover plate fixed to the position above the baffle.

Description

technical field [0001] The invention relates to a diesel generator set, in particular to an all-weather air-cooled diesel generator set. Background technique [0002] The normal ventilation and cooling of the diesel generator set is a necessary condition to ensure the rated power output of the unit. There are two main cooling passages for the air-cooled unit. One is to drive the cooling fan through the shaft belt pulley to cool the oil fins to take away the internal heat of the engine; the other is to radiate heat to the air through the cylinder block of the engine. In an open space, the unit can dissipate heat well to ensure normal operation, but it must work normally in an outdoor high-protection-level closed chassis. If the ventilation is not handled properly, it is easy to cause high-temperature shutdown. At the same time, components that are sensitive to high temperature, such as the starting battery in the chassis, will also age and be damaged quickly. Contents of t...
