Description
【0001】[0001]
本考案は、電気機器内部に発生した熱を外部に放出するための電気機器の強制 空冷装置に関する。 The present invention relates to a forced air cooling device for an electric device for discharging heat generated inside the electric device to the outside.
【0002】[0002]
従来、電気機器の強制空冷装置は、電気機器筐体に設けた入口部から、該入口 部に設けたほこりの侵入を防ぐウレタンスポンジや目の細かい金網などの塵埃防 御フィルタを通し、機器内部へ外気を取り入れ、この空気を内部発熱部に循環さ せ、熱量を吸収した後、出口部から外部へ放出させていた。 Conventionally, the forced air cooling system for electric equipment has been equipped with a dust control filter such as urethane sponge and fine mesh to prevent dust from entering through the entrance provided on the housing of the electric equipment. The outside air was taken in, and this air was circulated to the internal heat generating part to absorb the amount of heat and then released to the outside from the outlet part.
【0003】[0003]
しかしながら、この従来の電気機器の強制空冷装置にあっては、外気を電気機 器外部から取り入れ、風流を発熱部に通し、熱量を吸収した後、外部に放出する という一定方向の風流を作り出すことしかできないので、長年の使用により外気 取り入れの入口部に装備されている塵埃防御フィルタが、塵埃の付着による目づ まりを起こし、外気吸入量が減少し冷却効率の低下をまねくことがあり、この場 合には、機器の正常な動作に支障を来たし、発煙,火災などを引き起こす可能性 があるという問題点があった。 However, in this conventional forced air cooling system for electric equipment, the outside air is taken in from the outside of the electric equipment, the airflow is passed through the heat generating part, the heat quantity is absorbed, and then the airflow is discharged to the outside to create a unidirectional airflow. Since it can only be done for many years, the dust protection filter equipped at the inlet of the outside air intake may cause clogging due to the adhesion of dust, reducing the amount of intake of outside air and lowering the cooling efficiency. In this case, there is a problem that it may interfere with the normal operation of the equipment, and may cause smoke and fire.
【0004】 本考案は、上記の問題点にかんがみてなされたもので、塵埃フィルタの目づま りが生じないようにし、安全性の向上を図った電気機器の強制空冷装置の提供を 目的とする。The present invention has been made in view of the above problems, and an object of the present invention is to provide a forced air cooling device for an electric device that prevents the dust filter from being clogged and improves safety. .
【0005】[0005]
上記目的を達成するため本考案の電気機器の強制空冷装置は、電気機器筐体に 空気が通過する空気の入口部および出口部を形成し、この入口部および出口部に 塵埃フィルタを設けるとともに、正転により入口部から空気を筐体内に導入する 正逆可能なファンと、該ファンを正逆転させる駆動部と、ファンを所定時間逆転 させるよう駆動部を作動させる回転方向制御部とを備えた構成としてある。 In order to achieve the above object, the forced air cooling device for electric equipment of the present invention forms an air inlet part and an air outlet part through which air passes in an electric equipment casing, and provides a dust filter at the inlet part and the outlet part. A forward-reverse fan that introduces air from the inlet into the housing by forward rotation, a drive unit that rotates the fan forward and backward, and a rotation direction control unit that operates the drive unit to rotate the fan backward for a predetermined time are provided. It is as a configuration.
【0006】 そして、必要に応じ、上記回転方向制御部は、電気機器の電源投入時から所定 時間ファンを逆転させその後正転させるよう駆動部を作動させる機能を備えてい る構成としてある。Then, if necessary, the rotation direction control unit is configured to have a function of operating the drive unit so that the fan is reversely rotated for a predetermined time after the power supply of the electric device is turned on and then the fan is normally rotated.
【0007】[0007]
上記構成からなる電気機器の強制空冷装置によれば、回転方向制御部によって 駆動部を介してファンが所定時間逆転させられる。これにより、筐体内には出口 部から入口部に至る通常の冷却時の風流とは逆の風流が形成され、そのため、入 口部から排出される空気によって入口部の塵埃フィルタに付着した塵埃が外部に 吹き飛ばされる。 According to the forced air cooling device for an electric device having the above configuration, the rotation direction control unit causes the fan to rotate in the reverse direction for a predetermined time via the drive unit. As a result, an air flow that is the reverse of the air flow during normal cooling from the outlet to the inlet is formed in the housing, so that the dust discharged from the inlet to the dust filter on the inlet is filtered by the air discharged from the inlet. It is blown outside.
【0008】[0008]
以下、本考案の実施例について図面を参照して説明する。図1は本考案の実施 例に係る強制空冷装置を示す図である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a view showing a forced air cooling device according to an embodiment of the present invention.
【0009】 図において、3は電機部品等の発熱部6を収納した電気機器筐体である。この 筐体3には、空気が通過する空気の入口部7および出口部8が形成されている。 この入口部7および出口部8には、それぞれ、ウレタンスポンジや目の細かい金 網などの塵埃防御フィルタ5が設けられている。In the figure, reference numeral 3 is an electric device housing in which a heat generating portion 6 such as an electric component is housed. The housing 3 is formed with an air inlet portion 7 and an air outlet portion 8 through which air passes. A dust protection filter 5 such as urethane sponge or fine mesh is provided at each of the inlet portion 7 and the outlet portion 8.
【0010】 4は出口部8の後側に設けられた正逆転可能なファンである。このファン4は 正転により入口部7から空気を筐体3内に導入し、逆転により入口部7から空気 を排出する。1は該ファン4を正転逆転させるモータ等の駆動部である。Reference numeral 4 denotes a fan that is provided on the rear side of the outlet portion 8 and is capable of forward and reverse rotation. This fan 4 introduces air into the housing 3 from the inlet portion 7 by forward rotation and discharges air from the inlet portion 7 by reverse rotation. Reference numeral 1 is a drive unit such as a motor for rotating the fan 4 in the normal and reverse directions.
【0011】 2は回転方向制御部であって、電気機器の電源投入時から所定時間ファン4を 逆転させるよう駆動部1を作動させるとともに、所定時間経過後はファン4を正 転させるよう駆動部1を作動させるものである。Reference numeral 2 denotes a rotation direction control unit that operates the drive unit 1 so as to rotate the fan 4 in the reverse direction for a predetermined time after the power of the electric device is turned on, and drives the fan 4 in the normal direction after the predetermined time has elapsed. 1 is operated.
【0012】 したがって、この実施例に係る強制空冷装置によれば、回転方向制御部2によ り、電気機器の電源投入直後の一定時間、駆動部1を介してファン4が逆回転さ せられる。これにより、通常と逆の風流が作り出され、入口部7から空気が排出 される。そのため、この排出空気によって、塵埃防御フィルタ5に付着した塵埃 が吹き飛ばされる。所定時間経過後はファン4は正転させられ、通常の冷却用の 風流を生成する。Therefore, according to the forced air cooling device of this embodiment, the rotation direction control unit 2 causes the fan 4 to rotate in the reverse direction via the drive unit 1 for a certain period of time immediately after the electric device is powered on. . As a result, an air flow opposite to the normal one is created, and the air is discharged from the inlet 7. Therefore, the dust adhering to the dust protection filter 5 is blown off by the exhaust air. After a lapse of a predetermined time, the fan 4 is rotated in the normal direction to generate a normal cooling air flow.
【0013】[0013]
以上説明したように、本考案の電気機器の強制空冷装置によれば、制御部によ りファンを一定時間逆回転させ入口部の塵埃を吹き飛ばすことができるので、塵 埃防御フィルタの目づまりを防止することができ、目づまりによる動作不良を防 止して安全性の向上を図ることができるという効果を有する。 As described above, according to the forced air-cooling device for electric equipment of the present invention, the control unit can rotate the fan in the reverse direction for a certain period of time to blow off the dust at the inlet, thus preventing clogging of the dust protection filter. This has the effect of preventing malfunctions due to clogging and improving safety.
