Abstract
The invention discloses a cooling system of an engine generator, belonging to the technical field of generators. The outside of the engine generator is a noise enclosure, and an engine, a generator and a silencer are successively assembled in the noise enclosure. The cooling system of an engine generator is characterized in that the cooling system comprises a cooling fan linked with the engine, and the cooling fan is installed in a wind scooper; the engine heat protection shield covers the outside of the engine; a silencer heat protection shield covers the outside of the silencer; the wind scooper, the engine heat protection shield and the silencer heat protection shield are mutually communicated to form a main cooling air duct; the wind scooper is connected with a wind guidance tube; and the wind guidance tube and silencer heat protection shield are connected to form a secondary cooling air duct. In the invention, the cooling system is formed by the main cooling air fduct and the secondary cooling air duct, has compact structure and can effectively cool the engine and the silencer, in particular to the silencer.
Description
Technical field
The present invention relates to a kind of engine generator, relate to a kind of cooling system of engine generator more specifically, belong to technical field of generators.
Background technology
At present, traditional engine generator, mainly by blimp, engine, and form one by the generating body that engine drove, fuel tank is arranged on the top of blimp.By the above-mentioned engine generator of forming in the construction building site, it is not that very high occasion is widely used that the avenue even load requires, all the time, in the engine generator that generates electricity owing to driven by engine, during generating for sound insulation, generator and engine, even muffler, fuel tank, controllers etc. all are housed in the blimp, each parts meeting place of custody is very compact, but because engine and generating body can generate heat, and above-mentioned parts all are to be coated in the blimp, therefore, temperature in the blimp and the temperature that is coated on the muffler in the blimp can become very high, so, need in blimp, introduce other air, so that each parts that is housed in the blimp are played cooling effect.Yet exist so problem,,, be used further to cool off muffler, in fact can not reach good cooling effect because temperature can rise after the engine cooling promptly by the cooling air that imports in the muffler heat shield.So the very big muffler of volume that accounts for that is in engine generator is still located the condition of high temperature owing to cooling off effectively.
Summary of the invention
At the problems referred to above of prior art, the object of the present invention is to provide the cooling system of the engine generator of a kind of compact conformation, good cooling results.
The technical solution used in the present invention is as follows, a kind of cooling system of engine generator, the engine generator outside is a blimp, engine, generating body, muffler is equipped in the blimp in turn, it is characterized in that: cooling system comprises the cooling fan that is connected with engine, cooling fan is installed in the wind scooper, the engine heat shield is coated on the outside of engine, the muffler heat shield is coated on the outside of muffler, wind scooper, the engine heat shield, the muffler heat shield is interconnected and forms main cooling air channel, also be connected with guide duct on the wind scooper, guide duct links to each other with the muffler heat shield and forms time cooling air channel.
The further setting of the present invention is as follows: the engine heat shield of forming main cooling air channel is connected in an end of muffler heat shield, and it is corresponding with the engine heat shield that the guide duct of forming time cooling air channel is connected in the other end of muffler heat shield.
The present invention forms cooling system of the present invention by main cooling air channel and time cooling air channel, compact conformation, and can more effective engine and muffler be cooled off, especially can well cool off muffler.
The invention will be further described below in conjunction with the drawings and specific embodiments.

Embodiment
As shown in Figure 1, engine generator of the present invention 10 outsides are blimp 11, each parts of forming engine generator 10 all are housed in the blimp 11, in conjunction with Fig. 2, shown in Figure 3, in blimp 11, each parts of forming engine generator 10, comprise controller 12, engine 13, generating body 14 sets in turn, fuel tank 15 is installed on the top of engine 13 and is supported by blimp 11, in conjunction with shown in Figure 5, cooling system of the present invention comprises the cooling fan 16 that is connected with engine 13, in cooling fan 16 installations and the wind scooper 20, engine heat shield 21 is coated on the outside of engine 13, muffler heat shield 17 is coated on the outside of muffler 18, wind scooper 20, engine heat shield 21, muffler heat shield 17 is interconnected and forms main cooling air channel A, by also being connected with guide duct 19 on the wind scooper 20, guide duct 19 links to each other with muffler heat shield 17 and forms time cooling air channel B, in the present embodiment, the engine heat shield 21 of forming main cooling air channel A is connected in an end of muffler heat shield 17 (being muffler heat shield 17 tops shown in Figure 5), the guide duct 19 of forming time cooling air channel B is connected in the other end (being muffler heat shield 17 bottoms shown in Figure 5) of muffler heat shield 17, like this, the cooling system of being made up of main cooling air channel A and time cooling air channel B of the present invention can effectively cool off engine 13 and muffler 18.
Below sketch operation principle of the present invention: during work, driving the cooling fan 16 that is coated in the wind scooper 20 by engine 13 rotates, produce cooling air, the cooling air major part is through main cooling air channel A, cool off by 21 pairs of engines 13 of engine heat shield earlier, behind the cooling engine 13, the cooling air that temperature raises is further entered by muffler heat shield 17 tops, muffler 18 is cooled off again.And a fraction of cooling air enters into time cooling air channel B, promptly enters into guide duct 19 by wind scooper 20, is entered by muffler heat shield 17 bottoms through guide duct 19, directly muffler 18 is cooled off.Like this, on the one hand, can cool off muffler 18 behind the most of cooling engine 13 of the cooling air of going out by cooling fan, and owing to cooling engine 13 back cooling air temperature can raise, muffler 18 temperature are still than higher, by inferior cooling air channel B is that a fraction of cooling air that guide duct 19 is shunted away can directly cool off muffler 18 once more, thereby plays favorable cooling effect.Reasonable in design of the present invention is installed compactness, the experiment proved that the more original engine generator of cooling effect improves a lot.
