Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a package type engine generator, and more particularly to a package for housing a diesel engine generator or a gas engine generator having ventilation equipment.

[Prior Art] A package engine generator is an engine generator composed of a combination of a diesel engine or a gas engine and a generator, and is a box that houses the engine generator together with accessory electrical components. It is possible to prevent engine noise from directly spreading to the outside. The package is mainly made of steel plate, and if it is large, the soundproof material is put inside if necessary. In the conventional package, the second
As shown in the figure, a ventilation fan 14 is provided on one exhaust side of the ventilation windows 12 and 13 of the package 11 for ventilation of the inside so that outside air is taken in from the ventilation window 12 and the other ventilation window 13 is provided.
Discharge from. In the generator 7, the cooling fan 3 of its own
Is cooled through the intake port 7a and the exhaust port 7b. However, such ventilation has the following drawbacks.

A power supply and wiring for driving the ventilation fan 14 are required. Further, even if the ventilation fan 14 is turned, the temperature inside the package 11 rises uniformly above the outside air due to the heat generated by the generator 7 and the engine 6, so that the electrical components for the generator 7 and the engine 6 (electronic governor, controller). Etc.) may be adversely affected. Further, since the air to the combustion chamber of the engine is supplied from the air intake port arranged in the package having a temperature of extremely high heat as described above, the efficiency of the engine is also adversely affected.

[Problems to be Solved by the Invention] The present invention does not require special equipment such as a ventilation fan, its power source, and wiring for ventilation of the package, and the internal temperature of the package rises, so that the efficiency of internal electrical components and the engine is reduced. It is an object of the present invention to provide a package for an engine generator that does not adversely affect the engine.

[Means for Solving the Problems] In order to solve the above problems, an engine generator package according to the present invention is a diesel engine generator or a gas engine generator that has ventilation windows on the generator-side and engine-side end walls, respectively. In a package for accommodating a generator, a space between the intake port and the exhaust port of the generator includes a generator chamber and an engine chamber that are airtight in a space inside the package.
A partition plate is provided to divide the chamber into two chambers, the package is ventilated by the cooling fan of the generator, and an air inlet for supplying air to the combustion chamber of the engine is provided in the generator chamber.

[Operation] The partition plate divides the space inside the package into two chambers, the generator chamber and the engine chamber, between the intake port and the exhaust port of the generator,
Limiting the free circulation of air between these two chambers, the cooling air from the outside is drawn in from the air intake window on the generator side of the package through the intake port of the generator by the cooling fan of the generator, Restrict the flow path from the generator exhaust port to the package exhaust window. Since the air intake for supplying air to the combustion chamber of the engine is provided in the generator chamber that is separated from the engine chamber as described above, cold air taken from the outside air enters the combustion chamber of the engine. It will be supplied and the efficiency of the engine will be improved.

[Embodiment] FIG. 1 shows an embodiment of the present invention. Package 1 of the present invention
2 is different from the conventional package 11 shown in FIG. 2 in that the partition plate 2 has an intake port 7a (cooling air inlet) and an exhaust port 7 of the generator 7.
It is provided so as to divide the space inside the package into a generator room 8 and an engine room 9 at a position between b (cooling air outlet). In this case, a flexible elastic member 2a is used for the contact portion between the partition plate 2 and the outer periphery of the generator 7 so that these two chambers are airtight to each other. Further, in order to facilitate the inflow and outflow of the cooling air from the outside, the guide plates 4a and 5a are provided inside the intake window 4 and the exhaust window 5 of the package 1, if necessary. Further, the air intake 6a, which is supplied to the combustion chamber of the engine 6 through the air cleaner 10, penetrates the partition plate 2 so as to be located in the generator chamber 8 and is projected.

To explain the operation, the internal space of the package is separated by the partition plate 2 into the generator chamber 8 and the engine chamber 9 with the intake port 7a and the exhaust port 7b of the generator 7 as boundaries, and the flow of air between them is restricted. Therefore, the cooling air from the outside is drawn from the intake window 4 of the package 1 to the intake port 7 of the generator 7 by the suction force generated by the rotation of the cooling fan 3 of the generator placed on the engine room 9 side.
It flows through a and is discharged from the exhaust port 7b of the generator 7 into the engine compartment 9. The cooling air further cools the outer periphery of the engine 6 and is then exhausted to the outside through the exhaust window 5 of the package 1. In this case, cold air from the outside air is supplied to the combustion chamber of the engine from the air intake 6a through the air cleaner 10, so that the efficiency of the engine is improved. In this case, since the generator room 8 is isolated from the engine room 9, for example, the outside air temperature is 30%.
The temperature is 30 degrees, which is almost the same temperature as the outside air. In the engine room 9, the temperature of the exhaust gas from the exhaust port 7b of the generator 7 is about 45 degrees, but the temperature of the exhaust gas from the outer circumference of the engine 6 rises by about 30 degrees to 60 degrees from the outside air. Will be discharged from the outside. Therefore,
Among the electrical components of the engine 6 (electronic governor, controller, ignition coil, battery, etc.), those that are adversely affected by this temperature rise are incorporated in the generator room 8. The cooling fan 3 of the generator 7 needs to have a sufficient capacity to ventilate the inside of the package 1.

[Advantage of the Invention] The space inside the package is divided into two mutually airtight chambers at the position between the intake port and the exhaust port of the generator, so that only the cooling air from the outside is in one chamber of the package. The flow path is limited so that it is sucked from the intake window through the intake port of the generator by the cooling fan of the generator, discharged from the exhaust port into the other chamber, and then exhausted from the exhaust window. Therefore, the ventilation fan, the control device for the ventilation fan, and the power supply can be omitted, the structure of the package can be simplified, and extra auxiliary equipment is unnecessary.

In addition, the partition plate divides the chamber into a chamber that has almost the same temperature as the outside air and a chamber that has a relatively high temperature.By moving and installing the electrical components that are adversely affected by the high temperature into a chamber that has the same temperature as the outside air, It can protect electrical components.

If the air intake to the combustion chamber of the engine is placed in a room that has the same temperature as the outside air partitioned by the partition plate as described above, it will be placed in the generator room. Since the air of the same temperature is supplied, the efficiency of the engine is improved, and because the engine is located in the chamber on the relatively high temperature side, the difference from the temperature of the outer peripheral surface of the engine is small and the radiant heat loss of the engine is small. Efficiency is further improved. It is particularly effective when heat is recovered.
