Wind-cooling generating set end shield assembly with exhausting passage

Abstract

The invention relates to an end cover assembly of an air-cooled generating set with a discharge passage, and belongs to the technical field of frames or shells of machines or equipment. The feature is that the exhaust grille is placed in the lower part of the casing, and the front of the upper part of the casing is provided with a reinforcement structure, and the exhaust grille is provided with an engine exhaust port and a cooling exhaust port, and the engine exhaust port is located at the cooling exhaust port. In the middle of the outlet, there is a protruding sealing flange around the cooling air outlet, and the sealing rubber ring is tightly fitted on the sealing flange of the exhaust grille. The invention can improve the rigidity of the casing without increasing the weight, reduce the noise of the working machine from the direction of the casing; it can also reduce the internal temperature of the generator set, improve the operating environment of the engine, and is beneficial to the long-term stable operation of the generator set; The exhaust, heat dissipation, noise reduction and other functions are integrated together, which is light and firm, which not only reduces the overall weight of the generator set, but also reduces the production cost.

Description

technical field [0001] The invention relates to an end cover assembly of an air-cooled generator set with a discharge channel, and belongs to the technical field of frames or shells of machines or equipment. Background technique [0002] In the prior art, the existing mobile generator sets usually adopt the following structural forms to cool down the unit: [0003] 1. The open-frame structure can meet the heat dissipation requirements of the generator set to the greatest extent, and its manufacturing cost is low, but the engine noise of this structure is relatively large, which cannot meet the use requirements of some environments or occasions with limited noise; [0004] 2. The closed water-cooled structure means that all functional components of the generator set are placed in a closed cabinet, and the heat dissipation requirements of the generator are met through the cooling water tank, exhaust fan and more complicated air duct system. Although it meets people's requireme...

Problems solved by technology

[0003] 1. The open-frame structure can meet the heat dissipation requirements of the generator set to the greatest extent, and its manufacturing cost is low, but the engine noise of this structure is relatively large, which cannot meet the use requirements of some environments or occasions with limited noise;

[0004] 2. The closed water-cooled structure means that all functional components of the generator set are placed in a closed cabinet, and the heat dissipation requirements of the generator are met through the cooling water tank, exhaust fan and more complicated air duct system. Although it meets people's requirements for environmental protection and Aesthetics, but the manufacturing process is more complicated, and the commodity price is higher;

However, the engine exhaust ports of the currently known mobile generating sets are all arranged on the top of the casing, and the exhaust noise has a greater impact on the nearby crowd.
