Description
【０００１】[0001]
本考案は、シールドルーム（電磁波遮断室）の放熱装置に関する。 The present invention relates to a heat dissipation device in a shield room (electromagnetic wave shielding room).
【０００２】[0002]
シールドルームは、工作機械が発生する有害電磁波を遮断する囲み建屋として 知られている。一例としてアーク放電加工の場合について説明すると、鋳型をア ーク放電加工によって作製する時に火花が発生し、該火花による電磁波が近くに 存するテレビやコンピュータのモニターに到るとこれらの画面に映像不良を引き 起こさせ、ひいては計測や制御に不具合を生じさせる。そこで、上記電磁波に起 因する弊害を防止するためにアーク放電加工の作業をシールドルーム内で行なわ れる。 The shield room is known as an enclosed building that blocks harmful electromagnetic waves generated by machine tools. As an example of the case of arc electric discharge machining, sparks are generated when a mold is manufactured by arc electric discharge machining, and when electromagnetic waves due to the sparks reach a nearby TV or computer monitor, image defects occur on these screens. Cause a malfunction in measurement and control. Therefore, in order to prevent the harmful effects caused by the electromagnetic waves, the work of arc electric discharge machining is performed in the shield room.
【０００３】 上記シールドルームは、上述したように、室内で発生した電磁波を吸収して漏 れないように構成された組み立て建屋であって、この建屋を構成する天井板、前 後壁板、側壁板等の継目は、室の内外が電磁的に完全に遮断されるように、隙間 なく接続されている。換言すれば、室内の熱を逃しにくい構造とされている。As described above, the shielded room is an assembled building configured to absorb electromagnetic waves generated in the room so as not to leak, and includes a ceiling plate, front and rear wall plates, and side walls that constitute the building. The seams such as plates are connected without any gap so that the inside and outside of the chamber are completely electromagnetically shut off. In other words, the structure is such that the heat in the room is hard to escape.

ところで、工作機械にはオイルや水が用いられることが多く、これらを冷却す るためのオイルクーラーやウォータークーラー等の熱交換器が付属している。工 作機械とりわけ放電加工機の上記熱交換器からは大量の熱が放出され、シールド ルーム内の作業環境を悪化させるので、このような場合には、別途にルームクー ラーを用いている。ところが、ルームクーラーによるシールドルーム内の温度均 一化は甚だ困難であり、場所によっては温度がかなり異なってしまう不都合を生 じる。この温度不均一は、シールドルーム内で生産される製品の品質にばらつき を生じる不具合となって表われてくる。 By the way, machine tools often use oil or water, and a heat exchanger such as an oil cooler or a water cooler for cooling them is attached. A large amount of heat is released from the above heat exchanger of the working machine, especially the electric discharge machine, which deteriorates the working environment in the shielded room. In such a case, a room cooler is used separately. However, it is very difficult to equalize the temperature inside the shielded room by the room cooler, and the temperature varies considerably depending on the location. This non-uniformity in temperature appears as a defect that causes variations in the quality of products produced in the shielded room.
【０００５】 そこで本願考案は、前記オイルクーラーやウォータークーラー等の熱交換器よ り放出される熱を、シールドルーム外へ排出することを可能とするシールドルー ムの放熱装置を提供することを目的としている。Therefore, the object of the present invention is to provide a heat dissipation device for a shield room, which enables the heat released from the heat exchanger such as the oil cooler or the water cooler to be discharged to the outside of the shield room. I am trying.

A heat dissipation device for a shielded room according to the invention as defined in paragraph 1, wherein an opening for communicating with the inside or outside of the shielded room is formed, and an electromagnetic shielding member made of a wire mesh or having pores is arranged in the opening, The exhaust port of the heat exchanger of the machine tool installed in the above is airtightly connected to the opening with a flexible tube, and an intake fan is disposed in the flexible tube or in the vicinity of the opening inside the room, In addition, an air flow port communicating with the inside and outside of the flexible tube is provided between the intake fan and the exhaust port.
【０００７】[0007]
したがって、本願第１請求項に係る考案によれば、放電加工時に生じる火花に 起因する電磁波は、上記電磁波遮断部材に遮られて外部に漏れず、そして放電加 工時に熱交換器から排出される高温空気は、フレキシブルチューブ内を通って上 記開口から室外へと出てゆく。 Therefore, according to the first aspect of the present invention, electromagnetic waves caused by sparks generated during electric discharge machining are blocked by the electromagnetic wave blocking member and do not leak to the outside, and are discharged from the heat exchanger during electric discharge machining. Hot air passes through the flexible tube and exits the room through the above opening.
【０００８】 また、本願第２請求項に係る考案によれば、上記第１請求項に係る考案の作用 に加え、高温空気が吸気ファンによって強制的に室外へ排出される。According to the second aspect of the present invention, in addition to the function of the first aspect of the invention, high temperature air is forcedly discharged to the outside by the intake fan.
【０００９】 さらに、本願第３請求項に係る考案によれば、上記第２請求項に係る考案の作 用に加え、上記空気通流口から導入される空気によってフレキシブルチューブ内 の負圧化が避けられ、フレキシブルチューブが陥没等の変形を起こさず、従って 、上記排気口からの高温空気がシールドルーム外へスムーズに出てゆく。According to the third aspect of the present invention, in addition to the effect of the second aspect of the invention, the negative pressure in the flexible tube is reduced by the air introduced from the air flow port. It is avoided, and the flexible tube does not undergo deformation such as depression. Therefore, the hot air from the exhaust port smoothly flows out of the shield room.
【００１０】[0010]
以下、本考案を一実施例たる図１、図２に基づき説明する。図１（斜視図）に 示すように、シールドルーム１は、天井板２、前後壁板３、側壁板４によって可 及的に気密な組み立て建屋とされている。 Hereinafter, the present invention will be described with reference to FIGS. 1 and 2 as one embodiment. As shown in FIG. 1 (perspective view), the shield room 1 is made up of a ceiling plate 2, front and rear wall plates 3, and side wall plates 4 so that the building is as airtight as possible.
【００１１】 ５は、上記シールドルーム１内に配設された放電加工機（図示を省略）の熱交 換器であり、６は該熱交換器の排気口を示す。すなわち、上記シールドルーム１ 内で放電加工が行なわれる際に高熱が発生して当該加工機が高温化されるため、 該高温化の抑制手段として上記熱交換器５が設置されおり、上記熱交換器５の排 気口６からかなり高温の空気が排出される。そこで本願考案では、上記排気口６ から出てくる高温空気をフレキシブルチューブ７でシールドルーム１外へ導く構 成を採っている。Reference numeral 5 is a heat exchanger of an electric discharge machine (not shown) arranged in the shield room 1, and 6 is an exhaust port of the heat exchanger. That is, when electric discharge machining is performed in the shield room 1, high heat is generated and the temperature of the machining machine is raised. Therefore, the heat exchanger 5 is installed as a means for suppressing the temperature rise, and the heat exchange is performed. Air of a considerably high temperature is discharged from the exhaust port 6 of the container 5. Therefore, in the present invention, the flexible tube 7 guides the high temperature air coming out of the exhaust port 6 to the outside of the shield room 1.
【００１２】 図示実施例では、天井板２に開口８を形成し、該開口８の内側及び熱交換器５ の排気口６それぞれに取付け金具９，１０をボルト１１，１１で止着し、該取付 け金具９，１０間にアルミ製のフレキシブルチューブ７を接続配置させている。 取付け金具９，１０は、例えば円筒状のものに鍔を付けて形成し、この円筒部に フレキシブルチューブを固定し、また、鍔部を天井板２や排気口６に取付けるも のである。１２は、上記取付け金具９の下端に張設された網状の電磁遮断部材で あり、また、１３は上記取付け金具９内に配設された吸気ファンである。すなわ ち、排気口６から出てくる高温空気をフレキシブルチューブ７内に導き、更に、 吸気ファン１３で強制的に室外へ排出する構成としてある。In the illustrated embodiment, an opening 8 is formed in the ceiling plate 2, and fittings 9 and 10 are fixed to the inside of the opening 8 and the exhaust port 6 of the heat exchanger 5 with bolts 11 and 11, respectively. A flexible tube 7 made of aluminum is connected between the mounting brackets 9 and 10. The fittings 9 and 10 are formed, for example, by attaching a flange to a cylindrical shape, fixing a flexible tube to the cylindrical portion, and attaching the flange to the ceiling plate 2 and the exhaust port 6. Reference numeral 12 is a net-shaped electromagnetic shielding member stretched on the lower end of the mounting member 9, and 13 is an intake fan disposed in the mounting member 9. That is, the hot air coming out from the exhaust port 6 is guided into the flexible tube 7 and is forcedly discharged to the outside by the intake fan 13.
【００１３】 しかし、上記吸気ファン１３の吸引力が大きい場合には、フレキシブルチュー ブ７内が負圧となってフレキシブルチューブ７自体が陥没してしまう。そこで フレキシブルチューブ７の下部に空気通流口１４を形成している。However, when the suction force of the intake fan 13 is large, the pressure inside the flexible tube 7 becomes negative and the flexible tube 7 itself collapses. Therefore, the air flow port 14 is formed in the lower portion of the flexible tube 7.
【００１４】 なお、上記実施例では電磁遮断部材１２を網状物としているが、これに代わっ て、細孔を有する板状物としてもよい。また、上記吸気ファン１３は、フレキシ ブルチューブ７の中途部に配してもよく、また上記開口８は、シールドルーム１ の前後壁板３又は側壁板４に形成してもよい。Although the electromagnetic shielding member 12 is a net-like member in the above embodiment, it may be a plate-like member having pores instead. The intake fan 13 may be arranged in the middle of the flexible tube 7, and the opening 8 may be formed in the front and rear wall plates 3 or the side wall plates 4 of the shield room 1.
【００１５】[0015]
以上説明したように、本願第１請求項に係る考案によれば、工作機械の熱交換 器から出る高温空気がシールドルーム内に拡散されずにフレキシブルチューブに 導かれて室外へ出てゆき、この結果、シールドルーム内の温度分布が均一に保て ることになる。 As described above, according to the invention according to the first claim of the present application, the high-temperature air discharged from the heat exchanger of the machine tool is guided to the flexible tube without being diffused in the shielded room, and then flows out of the room. As a result, the temperature distribution inside the shielded room can be kept uniform.
【００１６】 また、本願第２請求項に係る考案によれば、本願第１請求項に係る考案の効果 に加え、高温空気が確実に室外へ導かれるという効果を奏する。According to the invention of the second aspect of the present application, in addition to the effect of the invention of the first aspect of the application, there is an effect that the high temperature air is reliably guided to the outside.
【００１７】 更にまた、本願第３請求項に係る考案によれば、本願第２請求項に係る考案の 効果に加え、フレキシブルチューブの形状が良好に保全されるという効果が加わ る。Further, according to the device of the third aspect of the present application, in addition to the effect of the device of the second aspect of the present application, the effect that the shape of the flexible tube is favorably maintained is added.
