Description

Cabin cooling device of generator set
Technical field
The utility model is related to a kind of cooling device of the generating set in cabin, and especially one kind can improve cold But effect and can reduce energy consumption generating set cooling device, belong to oil-electric engine technical group field.
Background technology
Desired raising and the demand of some industries are protected to environmental protection and to labourer with society, it is more and more Generating set no longer using it is open-shelf install, but use cabin formula(It is box)The pattern of installation, so as to reduce noise to periphery The influence of environment, and avoid erosion and influence of the environment on generating set.When generating set works, the hair in cabin The internal combustion engine and generator of group of motors must be adequately cooled, and the operating temperature of especially internal combustion engine is very high, if cooling reaches Less than requiring, the service life of internal combustion engine will be had a strong impact on.The radiator of existing internal combustion engine is the flabellum cooling using rotation, Flabellum is located on rear side of radiator, drives rotating shaft to rotate by I. C. engine crankshaft so that be fixed on the flabellum rotation of rotating shaft front end, band Dynamic air stream blows to radiator, and the heat of radiator is taken away, so as to reduce the temperature of internal combustion engine.When generating set works, by In flabellum always with internal combustion engine operation, noise is very big all the time;And flow through the air stream of generator and internal combustion engine main body and make Airflow temperature is increased while generator and internal combustion engine main body obtain cooling, forms the hot blast higher than environment temperature, hot blast Also the flabellum rotated blows over radiator so that the heat of radiator cannot be distributed, and causes generating set high energy consumption, efficiency It is low.The internal combustion engine cooled down using bleed type is limited due to reasons such as volumes, and flabellum is close apart from the core surface of radiator, blows over The annular region that the air of radiator is mainly projected by flabellum flows(Radiator core body is usually square-section), cooling effectiveness Further reduction.Therefore, going back special setting axial flow blower in cabin, open, further add after generating set is out of service The flowing of strong cooling air stream, it is to avoid the waste-heat cabin air of block surfaces after the shutdown of hot weather generating set, makes Personnel can not normal work;Also avoid miscellaneous equipment simultaneously is influenceed and is broken down by high temperature, and the axial flow blower set up enters one Step increases the energy consumption of existing generating set, increases the use cost of generating set.
Utility model content
The purpose of this utility model is to provide the cabin hair of cooling effect that is a kind of simple in construction and can improving generating set Group of motors cooling device.
The utility model is achieved by the following technical programs:
