A cooling structure for a generator set

Abstract

The invention relates to a cooling structure of a generating set, which includes an engine installed in a closed case, a permanent magnet generator, an electronic component installation box and a control system. The lower space of the type case is divided into the working area of ​​the unit and the heat exchange area by the water tank partition. The engine, generator, electronic component installation box and control system are installed in the working area of ​​the unit. The upper space of the closed case is separated by the top cover. The plate is divided into a hot air area and a cold air area. The cooling fan is set on the water tank partition. The working area of ​​the unit is connected to the heat exchange area through the cooling fan. The heat exchange area is connected to the hot air area through the hot air hole. connected. The invention can ensure the effective cooling of the components with large heat generation of the engine set, and realizes high-efficiency cooling of the engine set.

Description

technical field [0001] The invention relates to a cooling structure of a generating set. Background technique [0002] The water-cooled engine set requires enough cold air to cool the various high-heating parts of the generator set, such as the engine cylinder head, crankcase, permanent magnet generator and electronic components, etc., and at the same time meet the increasing environmental protection requirements, so the overall It has the characteristics of beautiful appearance, less pollution, low energy consumption and high space utilization rate. [0003] Before the present invention was made, in the overall configuration of the existing generating set, two configuration modes were adopted: [0004] 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 pollution environmental indicators; [0005] 2. Closed configuration means th...

Problems solved by technology

[0004] 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 pollution environmental indicators;

[0005] 2. Closed configuration means that all functional components of the generator set are placed in a closed cabinet, so that the heat dissipation requirements of the generator set can be met through a more complicated air duct system, and it can also meet people's requirements for environmental protection and aesthetics concept, but the manufacturing cost is relatively high, the commodity price is high, and the production process is relatively complicated, so it is not suitable for mass production

There are not many joint surfaces of this kind of cooling structure, and the cooling and ventilation chamber formed is easier to ensure the sealing requirements, but it cannot guarantee the place where the generating set generates a lot of heat (such as around the engine cylinder, the oil shell at the bottom of the engine, the permanent magnet generator, electronic components). ) for sufficient cooling
