Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a radiator-cooled power generator installed indoors.

[0002]

[Prior art]

 Generally, a power generation engine installed indoors is equipped with a radiator, and this radiator is cooled by cooling air from a cooling fan mounted on the engine. Exhaust gas that cools the radiator is exhausted to the outside, but an exhaust duct is provided to minimize ventilation resistance at that time.

However, depending on the installation condition inside the room, the exhaust duct may have a mixture of straight and curved portions, which increases ventilation resistance. When cooling a radiator with an engine driven fan, there is a limit to the air volume, and unless the resistance of the exhaust duct is suppressed to about 10 mmAg or less, the air volume in the duct will decrease and the cooling capacity will decrease, causing the engine to overheat. Will end up. Therefore, by design, if the allowable pressure loss of the engine drive fan is exceeded, the construction position of the generator is changed to reduce ventilation resistance, or a separate electric fan is installed inside the exhaust duct. .

FIG. 3 schematically shows a conventional power generator. As shown in the figure, a diesel engine 103 equipped with an AC generator 102 is fixed on a floor 101 installed indoors, and an engine driving fan 104 is attached to the diesel engine 103. There is. A radiator 105 is fixed on the front side of the diesel engine 103 adjacent to the engine driving fan 104, and the radiator 105 circulates and cools the engine cooling water of the diesel engine 103. As described above, the diesel engine 103 having the AC generator 102 and the engine driving fan 104 and the radiator 105 are fixed and unitized on the floor 101, and can be installed at a desired position in the house.

Further, such a generator is provided with an exhaust duct 106 for exhausting the exhaust gas, which has cooled the radiator 105, to the outside. One end of the exhaust duct 106 is connected to the radiator 105. , The other end is open to the outside. An electric fan 107 for increasing the exhaust capacity is attached to the middle of the exhaust duct 106.

As the diesel engine 103 is driven, cooling water is circulated between the diesel engine 103 and the radiator 105. Then, the diesel engine 103 is cooled by the outside air P introduced into the inside of the apparatus, and the radiator 105 is cooled by the air (outside air P) guided by the engine driving fan 104, and the exhaust gas Q is discharged by the exhaust duct 106 to the outside. Is discharged to. At this time, the flow of the exhaust gas Q in the exhaust duct 106 is assisted by the electric fan 107 and is surely discharged.

[0007]

[Problems to be solved by the device]

 However, in the above-described conventional power generator, the exhaust gas Q that has cooled the radiator 105 is sent into the exhaust duct 106 by the engine driving fan 104, but the ventilation resistance in the exhaust duct 106 is large and the exhaust capacity is insufficient. Therefore, the electric fan 107 assists ventilation in the exhaust duct 106. However, although the exhaust capacity is improved by mounting the electric fan 107 together with the engine driving fan 104 in the exhaust duct 106, the cost is increased by providing the electric fan 107 separately. Further, the electric fan 107 has to be mounted inside the exhaust duct 106, which causes a problem that the mounting work is troublesome and the mounting man-hour is increased.

The present invention solves such a problem, and an object of the present invention is to provide a power generation device capable of suppressing the cost and increasing the cooling and exhausting power.

[0009]

Means for Solving the Problems In order to achieve the above-mentioned object, a power generator of the present invention has a cooling radiator disposed adjacent to an engine equipped with a generator and a front surface of the cooling radiator. An electric fan is disposed on the side of the engine, and an exhaust duct is connected to the electric fan, and a cooling air passage is provided through which the cooling air of the engine is guided to the cooling radiator by the electric fan and discharged from the exhaust duct to the outside. It is characterized by being configured.

[0010]

[Action]

 The engine is cooled by the outside air introduced into the device, the radiator is cooled by the air guided by the electric fan, and the flow of the exhaust gas is fed into the exhaust duct by the electric fan to be reliably discharged.

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic view of a power generator according to an embodiment of the present invention, and FIG. 2 is a side view showing a main body portion of the power generator.

In the power generator of this embodiment, the main body is unitized so that it can be moved and attached as a unit. That is, as shown in FIG. 2, a diesel engine 13 equipped with an AC generator 12 is fixed on a floor 11 via a vibration-proof rubber 14. A radiator 15 is fixed to the front side of the diesel engine 13, and is connected by a connecting pipe 16 to circulate and cool the engine cooling water of the diesel engine 13. An electric fan 17 is attached adjacent to the radiator 15. As described above, the AC generator 12, the diesel engine 13, the radiator 15, and the electric fan 17 are fixed and unitized on the base 11, and in this state, it can be installed at a desired position indoors.
