Description

A kind of cooling structure of generator set
Technical field
The present invention relates to a kind of cooling structure of generator set.
Background technique
The water-cooled engine group, requirement has each high heating part such as engine cylinder head, crankcase body, permanent magnet generator and the electronic component etc. of abundant chilled air cools generator set, satisfy simultaneously the environmental requirement that improves day by day again, thus require integral body have appearance looks elegant, pollution less, characteristics such as low, the space availability ratio height of energy consumption.
Before the present invention makes, in the configured in one piece of existing generator set, adopt two kinds of configuration modes:
One, open-shelf configuration can be satisfied the heat radiation requirement of generator set so to greatest extent, and is cheap for manufacturing cost, but can not satisfy the requirement of befouling environment index;
Two, closed configuration promptly places each functional assembly of generator set in the rack of a sealing, like this can be by the ducting system of more complicated, reach the heat radiation requirement of generator set, and can satisfy people to environmental protection requirement and aesthetic conceptions, but manufacture cost is higher, the commodity price height, the production technology more complicated not too is applicable to production in enormous quantities.
These requirements have just been noticed in the box type electric generator in the closed generator product in present market, sealed completely as whole power and generator unit, they have adopted the ducting system of more complicated to strengthen the heat radiation of whole unit, have adopted the silencing apparatus of jumbo irregular how much external forms to reduce the measures such as discharging of noise.But these structures sometimes same as above all can strengthen the apparent size and the weight of complete machine, make the comparison heaviness that type becomes under the condition of identical mechanical property, place the comparison difficulty that becomes etc. in the environment of various hommizations.
Moreover in prior art, the generator set cooling structure normally adopts full encirclement formula cooling channel chamber, promptly with cooling off fan housing and cooling channel chamber wind scooper the full containing of motor, generator, outlet pipe, silencing apparatus integral body, cooling air by the cooling fan inspiration cools off the full surface of the above parts, and the back is by outside the air vent discharge side.This kind cooling construction junction plane is few, the cooling channel chamber that is constituted more easily guarantees seal request, but can't guarantee the place big to the generator set heating value (as around the cylinder, motor bottom oilcan, permanent magnet generator, electronic component) fully cool off.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the generator set cooling structure of the stable operation of a kind of high efficiency running that can effectively cool off, guarantee motor to generator set and electronic component is provided.

Motor, generator, electronic component install bin are installed on the same horizontal line in the unit working area, and control system is installed on the electronic component install bin.
In the cold wind district, be provided with the top cover dividing plate, have the ventilation space between the bottom of top cover dividing plate and the top cover connecting.
Described cold wind district is the reduced cross-sectional shape by its entrance point to its outlet end.
In the hot blast district, corresponding hot blast hole tip portion is provided with the wind deflector that is obliquely installed.
Be provided with the air intake barrier on closed cabinet, described air intake barrier bottom edge is arranged on the closed cabinet of bottom top of corresponding top cover dividing plate.
Top cover connecting upper surface in the hot blast district is provided with barrier plate, has the gap between described barrier plate and the top cover dividing plate.
The present invention compared with prior art has following advantage:
The present invention is simple in structure, compact, reasonable; Thereby use the cooling fan drive train inner air circulation cooling down high-temperature parts (electronic component, permanent magnet generator, motor) of motor, and electronic component and permanent magnet generator carried out the specific aim cooling, cooling air passes through outside the top cover hot blast district discharge side after heat exchange area carries out heat exchange, therefore this cooling structure is comparatively reasonable to the cooling of cluster engine, can guarantee the big parts of cluster engine heating value are effectively cooled off, realize high efficiency cooling cluster engine.
