Abstract
Description
本発明は、筐体内で発生する熱を効果的に外部に排出する排気ダクトを備えた電気機器収納用箱に関するものである。 The present invention relates to an electrical equipment storage box provided with an exhaust duct that effectively exhausts heat generated in a housing to the outside.
従来から、筺体の天井に排気ダクトを設けて筐体内の熱を外部に排出させる電気機器収納用箱が知られている。この場合、筐体内の熱は、排気ファンにより天井に位置する排気ダクト内に誘導されて排気口から排出されることになるが、例えば図５のように、排気ファン３を筐体の内側に突出形成した場合には、排気ファン３の側壁周辺の暖気が排気ダクト方向に十分誘導されずに筐体内で攪拌されるため、電気機器９の排熱が十分にされないという問題があった。そこで、図６のように、電気機器９の上部に仕切板１０を形成して空気の攪拌を防止することも考えられるが、電気機器９の取付スペースが制限されてしまうという問題が生じる。 2. Description of the Related Art Conventionally, an electric equipment storage box is known in which an exhaust duct is provided on a ceiling of a casing to discharge heat inside the casing to the outside. In this case, the heat in the housing is guided into the exhaust duct located on the ceiling by the exhaust fan and exhausted from the exhaust port. For example, as shown in FIG. 5, the exhaust fan 3 is placed inside the housing. In the case where the protrusion is formed, the warm air around the side wall of the exhaust fan 3 is not sufficiently guided in the direction of the exhaust duct and is stirred in the housing, so that there is a problem in that the exhaust heat of the electric device 9 is not sufficient. Therefore, as shown in FIG. 6, it may be possible to prevent the air from being stirred by forming a partition plate 10 on the upper part of the electric device 9, but there is a problem that the installation space of the electric device 9 is limited.
この問題を回避可能な構造として、排気ファンを排気ダクト内に設けた電気機器収納用箱も提案されている（特許文献１）。電気機器収納用箱は屋外に設置されることも多いが、特許文献１に記載の電気機器収納用箱は排気口が下向きに形成されているため、屋外に設置すると大雨時に雨水が排気口から浸入したり、暴風により塵などの異物が侵入して、電気機器に支障をきたす恐れがあった。 As a structure that can avoid this problem, an electric equipment storage box in which an exhaust fan is provided in an exhaust duct has also been proposed (Patent Document 1). Although the electrical device storage box is often installed outdoors, the electrical device storage box described in Patent Document 1 has an exhaust port formed downward, so that when it is installed outdoors, rainwater flows from the exhaust port during heavy rain. There was a risk of intrusion or intrusion of foreign substances such as dust due to storms, causing trouble to electrical equipment.
本発明の目的は前記問題を解決し、電気機器の十分な取付スペースを確保しつつ筐体内の暖気の攪拌を防止できるとともに、屋外に設置しても雨水や異物が侵入することのない電気機器収納用箱を提供することである。 The object of the present invention is to solve the above-mentioned problems, while preventing agitation of warm air in the housing while securing a sufficient mounting space for the electrical equipment, and preventing rainwater and foreign matter from entering even when installed outdoors. It is to provide a storage box.
上記課題を解決するためになされた本発明は、内部に電気機器を収納した筐体本体の天面から突出する排気ダクトを取り付けた電気機器収納用箱であって、該排気ダクトは、一端が筐体本体に形成された開口部に連設された筒状ダクト部と、該筒状ダクト部の他端に形成した折返部と、該折返部の端部に形成した排気口とからなり、該筒状ダクト部内には、筐体内部の排気を行う排気ファンを備え、該排気口を、排気ダクトの筒状ダクト部方向もしくは電気機器収納用箱より離れる方向に向けて開口形成したことを特徴とするものである。 The present invention made to solve the above-mentioned problems is an electric equipment storage box having an exhaust duct protruding from the top surface of a casing main body in which an electric equipment is housed, the exhaust duct having one end. A cylindrical duct portion connected to the opening formed in the housing body, a folded portion formed at the other end of the cylindrical duct portion, and an exhaust port formed at the end of the folded portion, An exhaust fan for exhausting the inside of the housing is provided in the cylindrical duct portion, and the exhaust port is formed to open toward the cylindrical duct portion of the exhaust duct or in a direction away from the electrical equipment storage box. It is a feature.
本発明に係る電気機器収納用箱は、一端が筐体本体の天面に形成された開口部に連設された筒状ダクト部と、該筒状ダクト部の他端に形成した折返部と、該折返部の端部に形成した排気口とからなる排気ダクトを備え、この排気口を排気ダクトの筒状ダクト部方向に向けて開口形成している。これにより、大雨や暴風時であっても雨水や塵等の異物が排気口から筐体内に侵入することを防止ができ、しかも排気口は外側から見えないので外観も良くなる。また、筒状ダクト部内に排気ファンを備えるので、筐体内の収納スペースを広げることができるとともに、筐体内の暖気の攪拌を防止して効果的に排熱を行うことができる。 An electrical equipment storage box according to the present invention includes a cylindrical duct portion connected to an opening formed at one end of the top surface of the housing body, and a folded portion formed at the other end of the cylindrical duct portion. An exhaust duct comprising an exhaust port formed at the end of the folded portion is provided, and the exhaust port is formed to open toward the cylindrical duct portion of the exhaust duct. Thereby, it is possible to prevent foreign matter such as rainwater and dust from entering the housing from the exhaust port even during heavy rain or storm, and the external appearance is improved because the exhaust port is not visible from the outside. Further, since the exhaust fan is provided in the cylindrical duct portion, the storage space in the housing can be expanded, and the heat can be effectively exhausted by preventing the warm air in the housing from being stirred.
特に、排気口を排気ダクトの筒状ダクト部方向に向けて形成すれば、結露が発生した場合や万が一排気口から雨水が侵入した場合であっても折返部内に水が溜まることなく排出されるので好ましい。 In particular, if the exhaust port is formed in the direction of the tubular duct part of the exhaust duct, water will be discharged without accumulating in the folded part even if condensation occurs or rainwater enters from the exhaust port. Therefore, it is preferable.
以下に本発明の好ましい実施形態を示す。
図１において、１は筐体本体、２は排気ダクト、３は排気ファンである。本発明に係る電気機器収納用箱は、筐体本体１と、筐体本体１の天井面から垂直方向に突出形成させた排気ダクト２と、排気ダクト２内に設けられた排気ファン３とから構成され、筐体本体１内の暖気を排気ファン３の運転により排気ダクト２を通って外部に排出させる構造のものである。
Preferred embodiments of the present invention are shown below.
In FIG. 1, 1 is a housing body, 2 is an exhaust duct, and 3 is an exhaust fan. An electric equipment storage box according to the present invention includes a housing body 1, an exhaust duct 2 that is formed so as to project vertically from the ceiling surface of the housing body 1, and an exhaust fan 3 provided in the exhaust duct 2. The warm air in the housing body 1 is configured to be discharged to the outside through the exhaust duct 2 by the operation of the exhaust fan 3.
筐体本体１内にはキュービクル等で使用する高圧機器やパワーコンディショナー、トランス、開閉器、配電盤等の電気機器が収納される。筐体本体１の天井面には排気ダクト２を接続する開口部４が形成されている。 The casing body 1 accommodates high-voltage devices used in cubicles and the like, and electric devices such as power conditioners, transformers, switches, and switchboards. An opening 4 for connecting the exhaust duct 2 is formed on the ceiling surface of the housing body 1.
排気ダクト２は断面略Ｔ字状をなし、一端を開口部４に連設した筒状ダクト部５と、筒状ダクト部５の他端に形成した折返部６と、折返部６の端部に形成した排気口７とからなり、この排気口７を図２に示すように筒状ダクト部５方向又は図３に示すように折返部６方向に向けて開口形成している。これにより、排気口７は外側から見えないので外観がよくなるとともに、雨水や塵等の異物が排気口７から筐体本体１内に侵入することを防止できる。 The exhaust duct 2 has a substantially T-shaped cross section and has a cylindrical duct portion 5 having one end connected to the opening 4, a folded portion 6 formed at the other end of the cylindrical duct portion 5, and an end portion of the folded portion 6. The exhaust port 7 is formed to open toward the cylindrical duct portion 5 as shown in FIG. 2 or toward the folded portion 6 as shown in FIG. Thereby, since the exhaust port 7 is not visible from the outside, the appearance is improved, and foreign matters such as rain water and dust can be prevented from entering the housing body 1 from the exhaust port 7.
図１及び図２に示す第１実施形態では、折返部６は断面Ｌ字状をなすので、排気口７は筒状ダクト部５の方向に向いているが、図３の第２実施形態のように、折返部６の先端をさらに垂直上向きに折り曲げて排気口７を電気機器収納用箱の筐体本体１から離れる方向となる上向きに、すなわち、折返部６方向に向けて形成することもできる。但し、この向きでは結露が発生した場合や万が一雨水が浸入した場合に折返部６内に水が溜まってしまう恐れがあるので、排気口７の開口方向を図１及び図２のように、筒状ダクト部５の方向に向けることが望ましい。 In the first embodiment shown in FIGS. 1 and 2, since the folded portion 6 has an L-shaped cross section, the exhaust port 7 faces toward the cylindrical duct portion 5, but the second embodiment of FIG. As described above, the tip of the folded portion 6 is further bent vertically upward so that the exhaust port 7 is formed upward in a direction away from the housing body 1 of the electrical equipment storage box, that is, toward the folded portion 6. it can. However, in this direction, there is a possibility that water may accumulate in the folded portion 6 when condensation occurs or rainwater enters, so the opening direction of the exhaust port 7 should be as shown in FIGS. It is desirable to direct in the direction of the duct portion 5.
さらに筒状ダクト部５の内壁には、排気ファン３を支持するブラケット８が取り付けられており、排気ファン３全体を筒状ダクト部５内に収めている。これにより、筐体内の暖気は排気ダクト２に誘導され、筐体内で滞留・攪拌することを防止できる。その結果、従来のように電気機器９の上部に仕切板１０を設ける必要もないので、筐体内の収納スペースを広げることができる。なお、本実施形態では排気ファン３をブラケット８で支持する構造としたが、これに限定されるものではなく、例えば筒状ダクト部５に直付けしてもよい。 Further, a bracket 8 that supports the exhaust fan 3 is attached to the inner wall of the cylindrical duct portion 5, and the entire exhaust fan 3 is accommodated in the cylindrical duct portion 5. Thereby, the warm air in the housing is guided to the exhaust duct 2 and can be prevented from staying and stirring in the housing. As a result, it is not necessary to provide the partition plate 10 on the upper portion of the electric device 9 as in the conventional case, so that the storage space in the housing can be expanded. In the present embodiment, the exhaust fan 3 is supported by the bracket 8. However, the present invention is not limited to this structure. For example, the exhaust fan 3 may be directly attached to the cylindrical duct portion 5.
上記においては排気ダクト２、排気ファン３、排気口７の位置関係について示したものであるが、以下に排気ダクト２の構造の詳細について説明する。図２及び図４に示すように、第１の実施形態の排気ダクト２は筒状ダクト部５、排気枠１１、フード１２からなる。筒状ダクト部５の一端は筐体本体１に取付形成し、筒状ダクト部５の他端は筒状ダクト部５から離れる方向に折り曲げ形成された折曲辺５ａ、折曲辺５ａより電気機器収納用箱の方向に垂下げて形成された垂下辺５ｂを形成している。排気枠１１は筒状ダクト部５より大きい枠体で面全体をパンチングメタルで形成した排気口７を有する排気面１１a、排気面より折曲げ形成した折曲辺１１bを形成している。フード１２は天面１２ａ及び天面１２ａの端部から垂下げ形成された側面１２ｂ、側面１２ｂよりフード１２の内側に折曲げ形成された折返面１２ｃから形成され、筒状ダクト部５及び排気枠１１を覆うように形成される。 In the above description, the positional relationship among the exhaust duct 2, the exhaust fan 3, and the exhaust port 7 is shown. Details of the structure of the exhaust duct 2 will be described below. As shown in FIGS. 2 and 4, the exhaust duct 2 of the first embodiment includes a cylindrical duct portion 5, an exhaust frame 11, and a hood 12. One end of the cylindrical duct portion 5 is attached to the housing body 1, and the other end of the cylindrical duct portion 5 is bent from a bent side 5 a formed in a direction away from the cylindrical duct portion 5. A hanging side 5b is formed by hanging in the direction of the device storage box. The exhaust frame 11 is a frame larger than the cylindrical duct portion 5 and has an exhaust surface 11a having an exhaust port 7 formed entirely of punching metal, and a bent side 11b bent from the exhaust surface. The hood 12 is formed of a top surface 12a and a side surface 12b that is suspended from the end of the top surface 12a, a folded surface 12c that is bent from the side surface 12b to the inside of the hood 12, and the cylindrical duct portion 5 and the exhaust frame. 11 is formed so as to cover 11.
筒状ダクト部５の左右面もしくは前後面の何れかにクランク状のブラケット１３を形成しており、ブラケット１３は筒状ダクト部５に取り付けられる取付面１３ｃ、取付面１３ｃより離れる方向に折り曲げた折曲辺１３ｂ、折曲辺１３ｂの端部から立上げた立上辺１３ａからなる。排気枠１１は筒状ダクト部５を覆うように取り付け、排気枠１１をブラケット１３にて仮保持させた状態で、排気面１１ａと筒状ダクト部５の垂下辺５ｂをねじで固定させる（図記載なし）。なお、この際、排気枠１１の高さは筒状ダクト部５の折曲辺５ａより突出しないようになっており、排気枠１１により通風路を阻害しないように形成している。また、フード１２の側面１２ｂの左右面もしくは前後面の何れかに取付孔１２ｄを形成しており、排気枠１１を筒状ダクト部５に取り付けた後、フード１２を被せ、側面１２ｂの取付孔１２ｄ、ブラケット１３の立上辺１３ａの取付孔１３ｄを対応させてねじ止め固定するものである。 A crank-shaped bracket 13 is formed on either the left or right surface or the front and rear surfaces of the cylindrical duct portion 5, and the bracket 13 is bent in a direction away from the mounting surface 13c and the mounting surface 13c attached to the cylindrical duct portion 5. It consists of a bent side 13b and a rising side 13a raised from the end of the bent side 13b. The exhaust frame 11 is attached so as to cover the cylindrical duct portion 5, and the exhaust surface 11 a and the suspended side 5 b of the cylindrical duct portion 5 are fixed with screws in a state where the exhaust frame 11 is temporarily held by the bracket 13 (FIG. not listed). At this time, the height of the exhaust frame 11 does not protrude from the bent side 5a of the cylindrical duct portion 5, and the exhaust frame 11 is formed so as not to obstruct the ventilation path. Further, attachment holes 12d are formed on either the left or right side or the front and rear surfaces of the side surface 12b of the hood 12, and after the exhaust frame 11 is attached to the cylindrical duct portion 5, the hood 12 is put on and attached to the side surface 12b. 12d and the mounting hole 13d of the upright side 13a of the bracket 13 are correspondingly fixed with screws.
なお、以上に説明した第１の実施形態の折返部６は、フード１２の天面１２ａの端部及び側面１２ｂ、折返面１２ｃ及び筒状ダクト部５の折曲辺５ａ及び垂下辺５ｂにより形成され、折返部６の端部に排気口７が形成される構造になるものである。また、第２の実施形態に示すように排気口７が折返部６方向を向くように形成する場合は、排気枠１１の上端を折曲形成し、折曲げ形成した上端を排気口７で形成し、その他の部分は板面で形成すれば良いものである。 In addition, the folding | returning part 6 of 1st Embodiment demonstrated above is formed of the edge part and side surface 12b of the top | upper surface 12a of the food | hood 12, the folding surface 12c, the bending side 5a of the cylindrical duct part 5, and the drooping side 5b. Thus, the exhaust port 7 is formed at the end of the folded portion 6. Further, as shown in the second embodiment, when the exhaust port 7 is formed to face the folded portion 6, the upper end of the exhaust frame 11 is bent and the bent upper end is formed by the exhaust port 7. However, other portions may be formed of a plate surface.
以上に説明したように、本発明に係る電気機器収容用箱は、排気口を筒状ダクト部方向、すなわち内側に向けて形成したので雨水や塵等の異物の侵入を阻止できる。さらに、排気ファンを筒状ダクト部５内に備えたので、電気機器の取付スペースを確保しつつ筐体内の暖気の攪拌を防止できる、等の利点を有する。 As described above, the electrical equipment storage box according to the present invention has the exhaust port formed in the direction of the cylindrical duct, that is, inward, so that entry of foreign matters such as rainwater and dust can be prevented. Further, since the exhaust fan is provided in the cylindrical duct portion 5, there is an advantage that warm air in the housing can be prevented from being stirred while securing a mounting space for the electric equipment.
