Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compressed air generator equipped with a compressor driven by a diesel engine.

Conventionally, as shown in FIG. 1, this type of device has been known in which an engine 3, a compressor 4, an oil cooler 5, a radiator 6, and a fan 7 are provided in a housing 2 having wheels 1. .

On the other hand, since the cooling areas of the oil cooler 5 and radiator 6 have been reduced in order to reduce costs, the fan 7 is driven to suck air through the housing opening 2'a to improve cooling efficiency. If the air inside the housing 2 is discharged to the outside by the fan 7, the cooling efficiency will be reduced.

In this case, the high temperature air that has cooled the oil cooler 5 and the radiator 6 is sucked into the housing 2, so the temperature inside the housing 2 becomes high, and the instruments, electrical components, etc. installed inside the housing 2 become high. The equipment 8 may come into contact with high-temperature air and be damaged by the heat, or it may become so hot that an operator cannot touch it with his/her hands and cannot operate it.

The present invention was developed in view of the above circumstances, and its purpose is to provide a compressed air generator that prevents equipment from becoming hot even when cooling air is sucked into the housing.

Embodiments of the present invention will be described below with reference to FIG. 2 and subsequent figures. The same members as the conventional one have the same symbols.

The housing 2 has an upper wall 2a, a lower wall 2b, and both side walls 2c, 2.
The opening 9 facing the oil cooler 5 and the radiator 6 is formed in one side wall 2c, and a net 10 and the like are provided.

A partition wall 11 bent in an L-shape is fixedly installed between the upper wall 2a and the other side wall 2c to form a space 12 isolated from the interior 2' of the casing 2, and this space 12 is connected to the other side wall 2c. The space 12 is opened to the outside through an inlet 13 formed in the air and connected to an air cleaner 15 via a pipe 14, thereby forming a space 12 as an intake air passage.

Devices 8 such as meters and electrical components are mounted so as to face into the intake air passage 12 from one end wall 2d.

16 is an eaves that prevents rainwater etc. from entering through the entrance 13.

Because of this, even if the inside of the housing 2 becomes high temperature, there is little heat effect on the equipment 8.Furthermore, since the equipment 8 comes in contact with the fresh cold air sucked in from the outside, it does not reach high temperatures and is protected from heat. This prevents damage from being caused by contact, and prevents it from becoming too hot to be touched by the operator.

Moreover, the upper wall 2 of the other side wall 2c in the housing 2
Since the partition wall 11 bent into a substantially L shape is attached between the side wall a and the side wall 2c of the upper wall 2a to form the space 12, the partition wall 11 is attached to the casing 2 of the conventional compressed air generator. Only 11 needs to be attached, so the number of parts does not increase, the cost does not increase, and manufacturing is simple.

Claims (1)

[Scope of utility model registration request] An opening 9 is formed in one side wall 2c of the casing 2 sealed by the upper wall 2a, the lower wall 2b, both side walls 2c, 2c and both end walls 2d, and the opening 9 is formed in the other side wall 2.
The upper wall 2a side surface of c and the other side wall 2 of the upper wall 2a
A partition wall 11 bent into a substantially L shape is attached to the inner surface 2' of the housing 2 to form a space 12 isolated from the interior 2' of the housing 2. The engine 3, compressor 4, radiator 6, and oil cooler 5 are installed so that the oil cooler 5 and radiator 6 face the opening 9, and the air cleaner 15 of the engine 3 is connected to the pipe 1.
4, an inlet 13 opening into the space 12 and opening the space 12 to the outside of the housing is formed on the other side wall 2c, and a device 8 is provided in the space 12.
