Problems solved by technology

Although this traditional structure can play a certain role in reducing the noise of the unit, this structure sacrifices the internal ventilation of the unit in exchange for reducing the emission noise.
This affects the heat dissipation performance of the diesel generator set, which in turn leads to a large power loss of the unit

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] see figure 1 Shown in -9, a kind of quiet type diesel generating set in the present embodiment mainly comprises engine 1, generator 2, silent cover 16, unit chassis 3, and engine 1 and generator 2 are all fixed on the unit chassis 3, and Isolated from the external environment by the quiet cover 16, two air inlets and two air outlets are provided on the quiet cover 16, including the first air inlet 4 and the first air outlet 6 that are opened on the engine 1 side, and opened on the generator. The second air inlet 5 and the second air outlet 12 on the 2 side, the air inlet and the air outlet adopt a louver structure to prevent dust and rainwater from entering the unit. Near the inside of the first air inlet 4, an axial flow fan 10 is arranged, and the axial flow fan 10 is installed in the inside of the quiet cover 16 through the axial fl...

Abstract

The invention relates to a silent type diesel generator set mainly comprising an engine, a generator, a silencing cover and a set chassis. An axial flow fan sucking cold air in the external environment into the silencing cover is arranged close to the inner side of a first air inlet. The axial flow fan directs the sucked cold air to a cooling device arranged on the inner side of the first air outlet for cooling. The cooling device is connected with a cooling liquid sleeve of the engine through a water inlet pipe and a water outlet pipe to cool the engine. A silencer is arranged above the engine and located close to a second air outlet. An air inducing shield which induces air from the horizontal direction to the vertical direction is arranged at the position of an outlet of the engine. An upper end air outlet of the air inducing shield is connected with an air director through an air guide channel, and air is guided to the silencer through the air director for cooling. According to the silent type diesel generator set, the cooling structure in the diesel generator set is improved, and the contradiction between silencing and cooling of the diesel generator set is effectively relieved.

Description

technical field [0001] The invention belongs to the manufacturing field of diesel generator sets, in particular to a silent diesel generator set. Background technique [0002] Diesel generator set is a kind of power generation equipment with diesel as the main fuel. The diesel engine is used as the driving force to drive the generator (ie electric ball) to generate electricity and convert kinetic energy into electrical energy and thermal energy. The whole set of diesel generating set is mainly divided into three parts: diesel engine, generator and controller. [0003] At present, most of the solutions to the heat dissipation of silent diesel generator sets are provided with air inlets and air outlets on the silent cover of the unit. Most of the noise problems are solved by adding traditional noise reduction and sound absorption structures to the unit. Although this traditional structure can play a certain role in reducing the noise of the unit, this structure sacrifices th...
