以下に本発明の好ましい実施形態を示す。 Preferred embodiments of the present invention are shown below.
本発明に係る電気機器収納用箱は、筐体内部にサーバやユニットなどの電気機器を収容するものであり、本実施形態では、図１、図２に示すように、正面扉１と左側面扉２を備えている。各々の扉には、扉を開閉操作するためのハンドル１０、１１が形成され、各ハンドル１０，１１は、操作方向が、互いに垂直方向となるように配置されている。電気機器を筐体内に収容する際には、正面扉１と左側面扉２の双方を、観音扉状に開放した状態として、大きな作業空間を確保することができる。筐体の底面には、配線導入部となるグロメット２７が形成されている。 The electrical equipment storage box according to the present invention accommodates electrical equipment such as a server and a unit inside a casing. In this embodiment, as shown in FIGS. A door 2 is provided. Handles 10 and 11 for opening and closing the doors are formed in each door, and the handles 10 and 11 are arranged so that the operation directions are perpendicular to each other. When the electric device is accommodated in the housing, a large work space can be secured by opening both the front door 1 and the left side door 2 in the form of a door. A grommet 27 serving as a wiring introduction portion is formed on the bottom surface of the housing.
図３に示すように、電気機器３は、一端に吸気口４、他端に排気口５を有し、吸気口４を左側面扉２に向け、排気口５を筐体の右側面６に向けて、筐体内に収容されている。電気機器３には、排気ファンを備えることが望ましい。 As shown in FIG. 3, the electrical device 3 has an intake port 4 at one end and an exhaust port 5 at the other end, with the intake port 4 facing the left side door 2 and the exhaust port 5 on the right side surface 6 of the housing. It is accommodated in the housing. It is desirable that the electrical device 3 includes an exhaust fan.
図２、３に示すように、筐体の左側面扉２には、電気機器３の吸気口４と対峙するように電子式クーラ７が配置され、筐体の右側面６には、電気機器３の排気口５と対峙するように放熱フィン８が配置されている。更に、筐体の正面扉１には、熱交換器９が、その吸気方向が電気機器３の排気方向と直交するように、配置されている。 As shown in FIGS. 2 and 3, an electronic cooler 7 is disposed on the left side door 2 of the housing so as to face the air inlet 4 of the electrical device 3, and an electrical device is disposed on the right side 6 of the housing. The radiating fins 8 are arranged so as to face the three exhaust ports 5. Furthermore, the heat exchanger 9 is arranged on the front door 1 of the housing so that the intake direction thereof is orthogonal to the exhaust direction of the electric device 3.
上記のように、３種類の冷却機器が配置された筐体内では、電子式クーラ７から排気された冷気は、電気機器３の吸気口４から吸い込まれて、電気機器３の内部を通過しながら冷却する。電気機器３の内部空気は、電気機器３の排気口５から排気され、放熱フィン８と接触して、ここで粗熱が除去される。粗熱が除去された空気は、その後、熱交換器９に導入される。熱交換器９内での熱交換で、冷却された空気は、電子式クーラ７の吸気口１２から吸い込まれた後、電子式クーラ７内で更に冷却された後、再度、電気機器３の吸気口４に向けて排気される。このように、３種類の冷却機器を用いて、冷却を行うことにより、コンプレッサを有するヒートポンプを利用するという高コストな手段によらずとも、電気機器収納用箱の冷却手段として十分な冷却能力を得ることができる。本実施形態においては、３種類の冷却機器を用いた構造として説明をするものであるが、熱交換器９及び放熱フィン８の２種の冷却機器を用いることも可能である。その場合、安価で構成することができ、熱交換器９単独で形成するよりも、冷却効率を向上させつつ筐体内部の冷却を行うことが可能である。また、３種類の冷却機器を用いて、冷却を行うことにより、筐体内の温度や外気温に応じた細やかな制御を行うことができる。制御パターンは、例えば、筐体内部が４０℃以上の場合には、熱交換器９及び電子クーラ７をＯＮ制御し、筐体内部が２０〜３０℃の場合には、電子クーラ７をＯＦＦ制御して、熱交換器９と放熱フィン８を使用し、筐体内部が１０〜２０℃の場合には、筐体内循環の為、熱交換器９のファン９ａまたは吸・排気口に形成したファンのみをＯＮ制御して放熱フィン８のみ使用し、筐体内部が０℃以下の場合には、結露防止の為、ペルチェ素子の極性を切替えヒータ運転するパターンなど、適宜最適なパターンを組み立てることができる。 As described above, in the case where the three types of cooling devices are arranged, the cold air exhausted from the electronic cooler 7 is sucked from the air inlet 4 of the electrical device 3 and passes through the interior of the electrical device 3. Cooling. The internal air of the electrical device 3 is exhausted from the exhaust port 5 of the electrical device 3 and comes into contact with the heat radiating fins 8, where coarse heat is removed. The air from which the crude heat has been removed is then introduced into the heat exchanger 9. The air cooled by heat exchange in the heat exchanger 9 is sucked from the air inlet 12 of the electronic cooler 7, further cooled in the electronic cooler 7, and then again taken into the intake air of the electric device 3. The air is exhausted toward the mouth 4. Thus, by using three types of cooling devices for cooling, sufficient cooling capacity as a cooling means for the electrical equipment storage box can be obtained without using an expensive means of using a heat pump having a compressor. Can be obtained. In the present embodiment, the structure is described as a structure using three types of cooling devices, but two types of cooling devices, that is, the heat exchanger 9 and the radiating fins 8 can also be used. In that case, it can be configured at low cost, and it is possible to cool the inside of the housing while improving the cooling efficiency, rather than forming the heat exchanger 9 alone. In addition, by performing cooling using three types of cooling devices, it is possible to perform fine control according to the temperature inside the casing and the outside air temperature. For example, when the inside of the casing is 40 ° C. or higher, the control pattern is ON control of the heat exchanger 9 and the electronic cooler 7, and when the inside of the casing is 20 to 30 ° C., the electronic cooler 7 is OFF controlled. When the heat exchanger 9 and the radiating fins 8 are used and the inside of the housing is 10 to 20 ° C., the fan 9a of the heat exchanger 9 or the fan formed on the intake / exhaust port for circulation in the housing If only the radiating fin 8 is used and only the heat radiation fin 8 is used, and the inside of the housing is 0 ° C or less, an optimum pattern such as a pattern for switching the Peltier element and operating the heater can be assembled to prevent condensation. it can.
本実施形態では、図３に示すように、筐体内に、筐体内の空間を、電気機器３の吸気口４側と排気口５側とに分離する仕切板２６を備え、仕切板２６により筐体内の冷却領域と排気領域を分離して冷却効率の向上を図っている。更に、この仕切板２６で仕切られた空間のうち、電気機器３の排気口５側の空間に熱交換器９の吸気口１７を配置し、電気機器３の吸気口４側の空間に熱交換器９の排気口１８を配置している。当該構成によれば熱交換器専用の仕切板が不要となるため、筐体内に配置される部品点数を削減することができる。図４に示すように仕切板２６の上下(詳しくは電気機器の上下)にはグロメット２７が形成され、排気側(吸気側)から電線を引込む際に使用できる構造となっている。図２に示すように、電気機器３を仕切板２６に取り付けた際に空隙が出来た場合にはブランクパネル２６ａを取り付けておくことも可能である。 In the present embodiment, as shown in FIG. 3, a partition plate 26 that separates the space in the housing into the intake port 4 side and the exhaust port 5 side of the electrical device 3 is provided. The cooling area and the exhaust area in the body are separated to improve the cooling efficiency. Furthermore, the air inlet 17 of the heat exchanger 9 is disposed in the space on the exhaust port 5 side of the electric device 3 in the space partitioned by the partition plate 26, and heat is exchanged in the space on the air inlet 4 side of the electric device 3. An exhaust port 18 of the vessel 9 is arranged. According to this configuration, a partition plate dedicated to the heat exchanger is not necessary, and the number of components arranged in the housing can be reduced. As shown in FIG. 4, grommets 27 are formed on the upper and lower sides of the partition plate 26 (specifically, on the upper and lower sides of the electrical equipment), and have a structure that can be used when an electric wire is drawn from the exhaust side (intake side). As shown in FIG. 2, when a gap is formed when the electric device 3 is attached to the partition plate 26, a blank panel 26 a can be attached.
電線の引込み位置は、電気機器の種類により異なる為、仕切板２６の上下や筐体の底面に形成したグロメット２７を膜状シートで形成し、電線で突き破って保持する構造とすることが好ましい。当該構造とすれば、電線は、膜状シート密着して保持されるため、電線の周囲からの空気漏れを防止することができる。膜状シートは、交換可能なタイプのものを使用することが好ましい。 Since the drawing-in position of the electric wire varies depending on the type of the electric device, it is preferable that the grommet 27 formed on the upper and lower sides of the partition plate 26 and the bottom surface of the housing is formed with a film-like sheet and is pierced and held by the electric wire. If it is set as the said structure, since an electric wire is closely_contact | adhered and hold | maintained, a film-like sheet | seat can prevent the air leak from the circumference | surroundings of an electric wire. It is preferable to use an exchangeable type sheet.
本実施形態では、図４に示すように、仕切板２６をクランク状に形成し、下端部を扉２側の吸気側に突出させている。これにより、扉１，２側からの配線作業を行い易く形成するとともに、開閉器２９・端子台３０などの配電機器の設置可能スペースを確保することができる。また、複数回折り曲げ形成により、仕切板２６を補強する効果も得ることができる。また、仕切板２６をクランク状に形成することによって、電気機器３の仮設置台としても使用可能である。 In the present embodiment, as shown in FIG. 4, the partition plate 26 is formed in a crank shape, and the lower end portion protrudes toward the intake side on the door 2 side. Thus, wiring work from the doors 1 and 2 can be easily performed, and a space for installing power distribution devices such as the switch 29 and the terminal block 30 can be secured. Moreover, the effect which reinforces the partition plate 26 can also be acquired by multiple bending bending formation. Further, by forming the partition plate 26 in a crank shape, the partition plate 26 can also be used as a temporary installation base for the electrical equipment 3.
本発明において、電子式クーラ７とは、冷媒や圧縮器等を使用しない、ペルチェ式のクーラを意味し、ペルチェ素子の吸気側および排気側にヒートシンクおよび換気扇を備えている。本実施形態では、図２に示すように、筺体の左側面扉２の上下２カ所に、電子式クーラ７を配置し、最下段には、各々の電子式クーラ７の制御を行う制御部１９を配置している。 In the present invention, the electronic cooler 7 means a Peltier cooler that does not use a refrigerant, a compressor, or the like, and includes a heat sink and a ventilation fan on the intake side and the exhaust side of the Peltier element. In this embodiment, as shown in FIG. 2, the electronic cooler 7 is arrange | positioned in the upper and lower two places of the left side door 2 of a housing, and the control part 19 which controls each electronic cooler 7 in the lowest stage. Is arranged.
放熱フィン８の形状や、配置数は、特に限定されないが、例えば、「剣山状」など、外気または内気に接触する面積がより多くなる形状とすること好ましい。その他、剣山状に形成した放熱フィン８に多孔質部材を形成することにより通気性を確保しつつ接触面積を増やした形状とすることもできる。本実施形態では、図２に示すように、筐体の右側面６の上下３カ所に、放熱フィン８を配置している。また、放熱フィン８の周囲には、図５に示すように、熱交換器９の吸気口１７に向けて排気を促すガイド部材１４を備えておくことが好ましい。ガイド部材１４を放熱フィン８の外周を囲むように配置することにより、電気機器３の排気口５から排出された空気を、効率よく放熱フィン８に導くことができる。電子式クーラ７の周囲にも、同様のガイド部材を設けてもよい。 The shape and the number of arrangement of the radiating fins 8 are not particularly limited. For example, it is preferable that the radiating fins 8 have a shape with a larger area in contact with the outside air or the inside air, such as “sword mountain shape”. In addition, by forming a porous member on the radiating fin 8 formed in a sword mountain shape, it is possible to obtain a shape with an increased contact area while ensuring air permeability. In this embodiment, as shown in FIG. 2, the radiation fin 8 is arrange | positioned at three places up and down of the right side surface 6 of a housing | casing. Further, as shown in FIG. 5, it is preferable that a guide member 14 that prompts exhaust toward the air inlet 17 of the heat exchanger 9 is provided around the heat radiating fins 8. By disposing the guide member 14 so as to surround the outer periphery of the radiating fin 8, the air discharged from the exhaust port 5 of the electric device 3 can be efficiently guided to the radiating fin 8. A similar guide member may be provided around the electronic cooler 7.
なお、筐体内外に温度差が出来た場合、放熱フィン８に結露が生じる場合があり、結露により生じた水滴が筐体内に溜まって錆等の要因となる恐れがあるところ、本実施形態では、結露対策として、図６に示すように、筐体の底面に、排水孔１５を備え、更に、図２に示すように、放熱フィン８を配置した筐体の右側面６下部には、放熱フィン８に生じた結露を、排水孔１５に向けてガイドする排水ガイド１６を配置する構造を採用している。排水ガイド１６は、排水孔１５に向けて傾斜させて形成されている。なお、排水ガイド１６は放熱フィン８に沿って形成しているため、熱交換器９の吸気口１７に向けて排気を促すガイド部材としての役割も担うものである。 In addition, in the present embodiment, when there is a temperature difference between the inside and outside of the housing, condensation may occur on the heat radiating fins 8 and water droplets generated by the condensation may accumulate in the housing and cause rust. As a countermeasure against condensation, as shown in FIG. 6, a drain hole 15 is provided on the bottom surface of the casing, and further, as shown in FIG. A structure is adopted in which a drainage guide 16 for guiding the condensation generated on the fin 8 toward the drainage hole 15 is arranged. The drain guide 16 is formed to be inclined toward the drain hole 15. Since the drainage guide 16 is formed along the heat radiating fins 8, it also serves as a guide member that urges exhaust toward the air inlet 17 of the heat exchanger 9.
熱交換器９の種類は、特に限定されない。本実施形態では、図２、図３に示すように、熱交換器９の左右端部側には、筐体内に向けて開口した吸気口１７と排気口１８が形成されている。冷却効率の向上を図るため、吸気口１７は、その吸気方向が電気機器３の排気方向と直交するように配置され、排気口１８は、電気機器３の吸気方向と直交するように配置されている。また、熱交換器９の排気口１８は吸気口１７よりも筐体内部に突出させて形成している。熱交換器９内に排気口１８を形成すると空気を循環するためのファンを配置させるために熱交換器９の幅方向が大きくなり、それに伴い筐体自体も大きくなってしまう問題がある。そのため、排気口１８及びファンを筐体内部に突出させるように形成し熱交換器９の幅方向を小さくしている。なお、吸気口１７は排気口１８より筐体外側に位置することにより、排気領域の空気を満遍なく吸い込むように形成している。 The kind of heat exchanger 9 is not particularly limited. In the present embodiment, as shown in FIGS. 2 and 3, the left and right ends of the heat exchanger 9 are formed with an intake port 17 and an exhaust port 18 that open toward the inside of the housing. In order to improve the cooling efficiency, the intake port 17 is disposed so that the intake direction thereof is orthogonal to the exhaust direction of the electric device 3, and the exhaust port 18 is disposed so as to be orthogonal to the intake direction of the electric device 3. Yes. Further, the exhaust port 18 of the heat exchanger 9 is formed so as to protrude from the intake port 17 into the housing. If the exhaust port 18 is formed in the heat exchanger 9, a fan for circulating the air is disposed, so that the width direction of the heat exchanger 9 is increased, and accordingly, the housing itself is also increased. Therefore, the exhaust port 18 and the fan are formed so as to protrude into the housing, and the width direction of the heat exchanger 9 is reduced. Note that the intake port 17 is located outside the housing from the exhaust port 18 so that the air in the exhaust region is uniformly sucked.
熱交換器９の下部には、図２に示すように、熱交換器９の制御を行う制御部２０を配置している。制御部１９、２０は、筺体内の空気循環の妨げにならないように、電子式クーラ７や熱交換器９の吸・排気口の下部、または電気機器３の下部に配置することが好ましい。 As shown in FIG. 2, a control unit 20 that controls the heat exchanger 9 is disposed below the heat exchanger 9. The control units 19 and 20 are preferably arranged below the intake / exhaust ports of the electronic cooler 7 and the heat exchanger 9 or the lower part of the electric device 3 so as not to hinder the air circulation in the housing.
本実施形態では、図３に示すように、放熱フィン８と熱交換器９を、筐体の外面側から、各々被覆する箱状の遮蔽部材２１，２２を備えている。この遮蔽部材２１，２２は、筐体の外気温の影響による筐体内の温度上昇を回避する機能を奏するものである。なお、図１に示すように熱交換器９を被覆する遮蔽部材２２には、ハンドル１０を露出させるための切欠部２３が形成されている。遮蔽部材２２は筐体側に向かって左右方向が幅広になるように形成した断面台形状に形成されているため、遮蔽部材２２の側面に切欠部２３を形成されるだけでハンドル１０を露出させることが可能である。 In this embodiment, as shown in FIG. 3, the box-shaped shielding members 21 and 22 which cover the radiation fins 8 and the heat exchanger 9 from the outer surface side of the housing are provided. The shielding members 21 and 22 have a function of avoiding a temperature rise in the casing due to the influence of the outside air temperature of the casing. As shown in FIG. 1, the shielding member 22 that covers the heat exchanger 9 is formed with a notch 23 for exposing the handle 10. Since the shielding member 22 is formed in a trapezoidal cross section formed so that the left-right direction becomes wider toward the housing side, the handle 10 is exposed only by forming the notch 23 on the side surface of the shielding member 22. Is possible.
図７に示すように、遮蔽部材２１，２２の側面には、通気孔２４、２５が形成されている。詳しくは、放熱フィン８を被覆する遮蔽部材２１の熱交換器８側の側面に通気孔２４を、熱交換器９を被覆する遮蔽部材２２の放熱フィン８側の側面に通気孔２５を形成している。これにより、放熱フィン８に換気扇がない場合でも、熱交換器９のファン９ａの作り出す空気流れを、通気孔２４、２５を介して放熱フィン８に導き、放熱フィン８を通過する空気流れを形成することができ、自然対流よりも熱交換を行う冷却効率が向上する。その他、図６に示すように、遮蔽部材２１，２２に、塞ぎ板２２ａを取付可能な開口部２６を複数設け、排気方向を自由に変更可能とすることもできる。 As shown in FIG. 7, vent holes 24 and 25 are formed on the side surfaces of the shielding members 21 and 22. Specifically, a vent hole 24 is formed on the side surface on the heat exchanger 8 side of the shielding member 21 covering the radiating fin 8, and a vent hole 25 is formed on the side surface on the radiating fin 8 side of the shielding member 22 covering the heat exchanger 9. ing. Thereby, even when there is no ventilation fan in the radiating fin 8, the air flow created by the fan 9 a of the heat exchanger 9 is guided to the radiating fin 8 through the vent holes 24 and 25, and the air flow passing through the radiating fin 8 is formed. Therefore, the cooling efficiency for heat exchange is improved compared with natural convection. In addition, as shown in FIG. 6, the shielding members 21 and 22 may be provided with a plurality of openings 26 to which the closing plate 22a can be attached, so that the exhaust direction can be freely changed.
