ることが望ましい。(Problem to be solved by the invention) A control equipment device that houses a control equipment unit is generally surrounded by an outer jacket, and a device that cools the inside, where the temperature rises due to heat generated by the built-in control equipment. It is desirable to effectively cool the heat-generating parts in the equipment storage chamber to equalize the internal temperature and keep the internal temperature rise within an allowable value.

成が複雑になると共に、コストが高い等の問題点
がある。 However, in order to keep the temperature of the high-temperature part within an allowable range, the equipment to be housed must be made larger, and if the internal temperature is uneven, the deterioration of the insulation part will be different, causing localized high temperatures. parts are prone to failure, shortening the life of the control equipment and resulting in reduced reliability. In particular, in control equipment installed at operation sites such as cotton spinning factories, it is difficult to detect cotton fiber fragments and dust that are usually 200 microns or larger that are visible to the naked eye inside the factory, but invisible to the naked eye of about 100 to 150 microns. Dust, etc. is floating in the indoor air. Therefore, in the case of such a control device installed at a site, when the fan is in operation, fluff and the like accumulates in the filter provided at the air intake port. Therefore, in order to obtain the necessary amount of air, the work of removing fluff must be carried out periodically, which is time-consuming. Furthermore, in the case of a closed type device provided with a heat exchange section, there are problems such as a complicated structure of the device and high cost.

を行なうことを余儀なくされる。 In particular, at textile mills, etc., if air fluff accumulates on rotating bodies such as fans of control equipment, the required air volume may not be obtained, and the rotation may stop or there is a possibility of combustion, which is dangerous. be. moreover,
Sparks that can be seen at the operating site of a spinning factory generate sparks when a control device's magnetic switch is turned on or off, or when a connecting terminal becomes loose, and this can cause a fire, making it difficult to operate safely. has also become a problem. Furthermore, the permissible limit for semiconductors in control equipment is around 100℃.
The temperature rise value must be kept within this range. For this reason, if a fan is installed around the intake or exhaust port to cool the control equipment room by forced convection, the dust-proofing device will become more clogged.
If the operation is not stopped, the attached fluff, etc. will not fall off naturally, and in some cases, it may be necessary to periodically remove the fluff, etc.

The drawback was that the cooling effect deteriorated.

止しようとするものである。(Means for Solving the Problems) The present invention has been developed in consideration of the fact that forced ventilation using conventional methods is difficult to ventilate the control equipment in spinning factories where there is a lot of fluff, etc. as mentioned above. The structure is as simple as possible, and airflow is circulated inside the control equipment room for ventilation without clogging dust filters, etc., while cooling air is effectively sent to the heat generating parts of the control equipment to maintain the indoor temperature. This aims to prevent a rise in the number of devices, as well as a decline in the trustworthiness of the equipment.

At least one exhaust opening equipped with a dustproof filter and/or screen is provided in the control room, and natural convection flowing in the control room and a fan that locally cools the heat generating part of the control device are installed in the intake opening and the exhaust opening. A spinning mill characterized in that it is installed at a location as far away as possible from the air outlet, so that the naturally rising high-temperature air flow generated by the forced convection flow is merged with the natural rise and discharged from the exhaust port. The purpose of this invention is to provide a ventilation device for dust-proof control equipment.

３より外部へ放出される構成となつている。 The ventilation device for dustproof control equipment according to the present invention has the above-mentioned general structure, and in this structure,
When the control equipment is in operation, as the internal temperature rises due to the high heat generated by the heat generating part 7, cold air from the outside is sucked in through the intake opening 2 provided in the bottom part 4, as shown by the arrow, and flows into the control equipment room 9. In addition to forming an air passage for natural convection 11 inside, on the other hand, as shown in FIG. A wind path of forced convection 12 is formed near the heat generating part 7 by the fan 8, and the high-temperature air flow rises and merges with the natural convection 11, as shown in FIG. The gas is discharged to the outside through at least one exhaust opening 3 provided in the upper part of the side surface.

少なく、蓄積があつても問題とならない。 As described above, the control device according to the present invention can be used at operational sites such as cotton spinning factories where a lot of fluff floats and scatters, unlike the conventional one in which a fan is attached to the intake or exhaust port. The suction of fluff, etc. can be significantly reduced. Also,
Since natural convection occurs in the control equipment room 9, the wind speed is low, so there is little accumulation of fluff, etc. in the intake opening 2, and even if there is accumulation, it does not pose a problem.

This is because natural convection and the natural rise of high-temperature airflow formed by forced convection that locally cools the heat generating part with a fan are combined and released from the exhaust opening provided at the upper part of the side part.
During operation, as the internal temperature within the control equipment room increases, cool air is sent to the heat generating section along with natural convection, so that the room is effectively cooled.

善する点で効果は顕著である。 Therefore, it is possible to solve the problem of the conventional apparatus in which the dust-proof filters and the like provided at the intake opening or the exhaust opening are easily clogged with fluff and the like, which is also a problem in terms of operational management. Furthermore, in the event that the cooling effect decreases due to the accumulation of fluff and the like and the internal temperature rises abnormally, it is possible to avoid the effect on the semiconductors in the control equipment, for example, where the permissible limit is around 100°C.
Furthermore, when using a fan, etc., sparks generated outside the control equipment room can spread fluff and pose a high risk of fire, but sparks inside the room do not propagate and pose no problem. The effect is remarkable in terms of improving the cooling method used as a ventilation device for control equipment in textile factories and the like where there are many.
