Abstract

PURPOSE:To obtain control center units which efficiently radiate heat generated large heat-generators inside the units without allowing the heat to stay in the units, and which require no large heat-radiation space inside the units. CONSTITUTION:A ventilation duct 7 is provided just above a large heat generator 4 installed inside a unit 2. The duct 7 is designed to discharge heat to outside through a ventilation opening 8 in a unit side plate 3, thereby radiating heat, generated from a large heat-generator 4, to outside through the space isolated by the ventilation duct 7, unallowing the heat to stay inside the unit. Thus, the other devices inside the unit do not need to be highly heat-resistant nor to be constituted such that they are not affected by heat, resulting in cutting cost of the unit.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system for a control center unit.

[0002]

2. Description of the Related Art FIG. 6 is a front view showing a control center in which conventional units are stored in multiple stages, and FIGS. 7 and 8 are a front view and a side sectional view showing those units. In the figure, 1 is a box of a control center, 2 is a unit that is housed in multiple stages inside this box, 3 is a side plate formed on the side of this unit, 4 is a device that has a large amount of heat and is placed inside the unit, 5 is a unit door arranged in the front opening of the unit, 6 is an opening for radiating the heat generated by the large heat generating device 4 housed in the unit to the outside of the unit. Is.

Since the unit of the conventional control center is constructed as described above, heat generated from the device 4 having a large heat generation stored in the unit 2 rises in the unit and is arranged at the front opening. Upper opening 6 of the door 5
More heat is dissipated to the outside.

[0004]

In the unit of the conventional control center as described above, heat generated from the device 4 having a large heat generation that rises in the unit 2 is generated in the unit above the upper opening 6 of the door 5. Since it accumulates and raises the air temperature in this unit, it is necessary to make other equipment housed in the unit highly heat resistant and to have a structure that is not affected by heat. There was a problem that it was expensive.

Further, in order that the heat generated from the device 4 which generates a large amount of heat rises smoothly in the unit 2 and is efficiently radiated from the upper opening 6 of the door 5 to the outside of the unit,
There is also a problem in that a large space is required near the upper opening 6 of the door 5 and the upper portion of the appliance 4 which generates a large amount of heat in the unit, which makes the unit too large.

The present invention has been made in order to solve such a problem, and heat generated from a large heat generating device housed in the unit is efficiently radiated to the outside of the unit without staying in the unit. Another object is to obtain a unit that does not require a large space for heat dissipation in the unit.

[0007]

A unit of a control center according to the present invention is a ventilation system in which the heat generated by a heat-generating device is opened in a side plate or a rear plate of the unit immediately above a device having a large heat generation stored in the unit. The ventilation duct is arranged so as to be guided from the mouth to the outside of the unit.

Further, a ventilation fan is attached to a ventilation opening formed in a side plate or a back plate of the unit.

Further, a wire mesh for preventing foreign matter from entering from the outside of the unit is attached to a ventilation opening formed in a side plate or a back plate of the unit.

[0010]

In the unit of the control center constructed as described above, the heat generated from the equipment with a large heat generation contained in the unit passes through the ventilation duct arranged above the heat generating equipment and the side plate or back plate of the unit. Heat is dissipated to the outside of the unit from the ventilation port opened in.

Further, the ventilation fan attached to the ventilation opening provided in the side plate or the back plate of the unit efficiently dissipates heat generated from a device having a larger heat generation and arranged inside the unit.

Further, a wire mesh attached to a ventilation opening formed in a side plate or a rear plate of the unit prevents foreign matter from entering the unit from the outside.

EXAMPLES Example 1. FIG. 1 is a perspective view of a unit of a control center showing an embodiment of the present invention, and FIG. 2 is a front view of a state in which the units are stored in multiple stages. In the figure,
Reference numeral 2 is a unit, 3 is a side plate formed on the side surface of the unit, 4 is an instrument with a large heat generation housed in the unit, 7 is disposed immediately above the instrument 4 with a large heat generation, It is a ventilation duct formed so as to guide the heat generated by the large appliance 4 toward the ventilation opening 8 formed in the side plate 3.

In the unit of the control center constructed as described above, the heat generated from the device 4 having a large heat generation accommodated in the unit 2 passes through the ventilation duct 7 arranged above the device 4 and passes through the unit. The heat is radiated to the outside of the unit through the ventilation port 8 formed in the side plate 3 of the.

Example 2. FIG. 3 shows that in the unit of the first embodiment, a ventilation fan 9 is provided in the ventilation opening 8 formed in the side plate 3.
The ventilation fan 9 promotes heat radiation from the equipment 4 having a large heat generation housed in the unit 2 to the outside.

Embodiment 3. Further, FIG. 4 shows that in the unit of the first embodiment, the wire mesh 1 is provided in the ventilation opening 8 formed in the side plate 3.
The wire mesh 10 prevents foreign matter from entering the inside of the unit through the ventilation port 8 from the outside of the unit.

Embodiment 4. FIG. 5 is a unit side sectional view of a control center showing Embodiment 4 of the present invention. In the figure, reference numeral 11 denotes a back plate formed on the back surface of the unit 2, and the ventilation duct 7 arranged above the appliance 4 having a large heat generation housed in the unit 2 is provided from the appliance 4 having a large heat generation. Ventilation port 1 where heat is generated in the back plate
2 is formed so as to be guided to the back side 2, and heat generated from the device 4 having a large heat generation passes through the ventilation duct 7 and the back plate 1
Heat is radiated to the outside of the rear of the unit through the ventilation port 12 formed in 1.

[0018]

Since the present invention is constructed as described above, it has the following effects.

A ventilation duct is provided in the unit, and the heat generated by the large-heat-generating equipment housed in the unit is radiated to the outside of the unit through the space defined by the ventilation duct. Therefore, it is not necessary to make other appliances housed in the unit highly heat resistant or to have a structure that is not affected by heat, so that an inexpensive unit can be obtained. .

Further, since heat generated from a device having a large heat generation can be dissipated to the outside of the unit only in the space of the ventilation duct, the unit can be downsized.

Further, by attaching a ventilation fan to the ventilation opening provided in the side plate or the back plate of the unit, it is possible to store a device having a larger heat generation in the unit.

Further, by attaching a wire mesh to the ventilation opening provided on the side plate or the back plate of the unit, it is possible to prevent foreign matter from entering the unit from the outside of the unit through the ventilation port, and the unit is highly safe. Is obtained.
