Abstract
The utility model relates to a cooling apparatus of the generator group, especially a cooling apparatus of whole-closed type generator group, including a engine arranged in the closed type case. A generator is arranged on the case side of the engine, and a front fan is arranged on the generator, while a cooling apparatus is disposed on the other side of the generator case. The utility model adopts the two cooling apparatuses having a front fan and a back fan, which can use the cold wind source for full cooling on the high temperature part in a near distance, with a evident effect, meanwhile, fully use the installation device of the back fan on the principal axis of the generator, to effectively save the energy and advance the efficiency.
Description
Technical field
The utility model relates to a kind of cooling device of generating set, particularly relates to a kind of cooling device of totally enclosed type generating set.
Background technology
The totally enclosed type generating set places in the rack of a sealing because of each functional assembly with generating set, generating set is when work, parts such as engine cylinder head, cylinder body, crankcase, generator can produce quite high heat, need fully cool off, easily cause engine to crash because of cooling effect is bad.At present, the cooling of solution totally enclosed type generating set is normally adopted and is improved the heat radiation that ducting system is improved whole unit, as disclosed Chinese patent ZL200420026342.2 on April 6th, 2005, name is called " a kind of gasoline engine generator group ", adopt in the closed cabinet petrol engine is installed, permanent magnet generator is installed on the casing of engine, handle tray is installed in the front end face of cool air suction cover, cool air suction cover adopts securing member to be connected with engine housing, handle tray employing securing member and cool air suction cover connect and compose power and cool off main inlet channel, described engine comprises an engine housing at least, the engine housing side cover, engine crankshaft, engine upper guide aerofoil, engine bottom wind deflector, engine cylinder cover, cylinder cover of engine, cylinder cover of engine adopts securing member to be connected with engine cylinder cover, engine housing upper guide aerofoil is installed in the top of the parallel engine housing of the installed surface of the main shaft of engine and engine, form cooling ventilation duct A, engine bottom wind deflector is installed the bottom because of the parallel engine housing of the installed surface of the main shaft of engine and engine, forms cooling ventilation duct C.This utility model is to adopt cool air suction cover and wind deflector with generator, blast pipe, the whole containing of muffler, by cooling air channel above-mentioned parts is cooled off by cooling fan inspiration cold wind again, and the back is by outside the air discharge duct discharge side.This kind type of cooling, adopt No. one cooling fan inspiration cold wind, should be relatively good to the cooling effect that rigidly connects the parts that contact cold wind such as generator, but afterwards will be by complicated and very long cooling air channel parts such as the engine housing very high to heating, cylinder cap, engine bottom oilcan, the muffler of rear end etc. cools off, its effect is just not too obvious, behind these high-temperature components of the long distance process of cooling air, wind in the cooling air channel neither be cold, but has quite high temperature, allow it high-temperature component be cooled off this moment again, and its effect is undesirable also well imagines.Often, cooling effect rises poor lubrication, problems such as vicious circle such as fuel feeding deficiency or engine deadlock in the practice because of significantly not causing the oil temperature in the oilcan.Moreover adopt complicated cooling air channel pattern, its cost also rises thereupon.
Summary of the invention
Problem to be solved in the utility model provides a kind of cooling device of simple in structure, the significant totally enclosed type generating set of cooling effect.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model provides a kind of cooling device of totally enclosed type generating set, comprise the engine that is located in the closed cabinet, casing one side at engine is provided with generator, on generator, be provided with forefan, on described closed cabinet, be provided with some air inlets, be provided with ventilating fan, on described closed cabinet, be provided with air outlet at the opposite side of engine housing.
Described ventilating fan is provided in a side of on the engine spindle.
Described ventilating fan is provided in a side of on arbitrary position of engine housing with respect to the opposite side of forefan, provides the ventilating fan power supply by generator.
The utility model adopts the two-way cooling device of forefan and aft-fan, can at utmost utilize the cold wind source that high-temperature component is carried out in-plant abundant cooling, and effect is obvious.This carries out the installation setting of aft-fan in the main shaft that uses to make full use of engine simultaneously, can effectively save and can raise the efficiency.
Description of drawings
Fig. 1: the general assembly front view of the utility model embodiment.
Embodiment
Below, with accompanying drawing the utility model is described in more detail in conjunction with the embodiments.
Embodiment 1: see Fig. 1, a kind of cooling device of totally enclosed type generating set, comprise the engine 4 that is located in the closed cabinet 1, casing 5 one sides at engine are equipped with generator 3, are provided with forefan 2 on generator 3, are provided with some air inlets 11 on described closed cabinet 1, air inlet 11 is located at the bottom of cabinet 1, both sides etc. are provided with ventilating fan 7 at the opposite side of engine housing 5, are provided with air outlet 13 on described closed cabinet 1.Described ventilating fan 7 is provided in a side of on the engine spindle 6, is provided with muffler 8 on engine 4, and forms air duct 9 with engine 4 fin, and muffler 8 is provided with wind scooper 10, and this wind scooper 10 is on described ventilating fan 7.Introduce in the closed cabinet 1 by the air that the air inlet on the cabinet 1 11 is outer with cabinet, the main two-way that divides of the cold air heat radiation of introducing, one tunnel cooling is the air inlet 12 by forefan 2, fin and air duct 9 along generator 3, engine 4, have an exhaust outlet and air duct 9 at muffler 8 rear portions and give the exhaust heat radiation, in exhaust ports individual wind scooper 10 is arranged, this wind scooper 10 is to prevent that the hot gas of discharging from being sucked cooling once more by ventilating fan 7 again, causes cooling effect bad.The type of cooling can be taken away the cylinder head of generator, engine and the heat of cylinder body and muffler effectively in a large number like this; Another road cooling is the opposite side at forefan 2, and engine 4 main shafts are provided with powerful ventilating fan 7, and this ventilating fan 7 is that all heats in engine 4 casings, oilcan and the closed cabinet are carried out strong heat absorption up hill and dale, and by air outlet 13 exhausts cooling.The two-way cooling device carries out fully a large amount of cooling to casing, cylinder head and cylinder body, engine oilcan and the muffler etc. of generator, engine simultaneously.
Embodiment 2: compare with embodiment 1, difference is different on the installation site of ventilating fan 7, not on the main shaft of engine, but on the casing of engine.Particularly, engine housing 5 with respect to forefan 2 opposite sides on ventilating fan 7 is installed, ventilating fan 7 provides and can provide by generator 3 for the power supply of ventilating fan 7 also below wind scooper 10, also can provide drive energy by engine 4, other are identical with embodiment 1.
