以下、本発明の実施の形態１について図１〜３を参照しながら説明する。
(Embodiment 1)
Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS.

FIG. 3 is an external view of the outside of the heating element storage box cooling device according to Embodiment 1 of the present invention, in which a plurality of heating element storage box cooling devices A are installed in the horizontal direction (each figure shows the case of two installations). It shows the state of
発熱体収納箱冷却装置Ａは発熱体収納箱Ｂの扉Ｃに取り付けられ、「扉一体型」装着にて構成されている。 The heating element storage box cooling device A is attached to the door C of the heating element storage box B, and is configured by “door integrated type” mounting.
なお、発熱体収納箱冷却装置Ａは発熱体収納箱Ｂの扉Ｃに取り付けとしたが、発熱体収納箱冷却装置Ａは発熱体収納箱Ｂの扉Ｃまたは壁面に外付けもしくは内付けでもよい。 Although the heating element storage box cooling device A is attached to the door C of the heating element storage box B, the heating element storage box cooling device A may be externally attached or attached to the door C or the wall surface of the heating element storage box B. .
以下、発熱体収納箱冷却装置Ａの内部構成について説明する。 Hereinafter, the internal structure of the heating element storage box cooling device A will be described.
発熱体収納箱Ｂ内の空気（以下、これを内気と称する）は内気吸込口２より内気送風機３のターボファン１５に取込まれた後、熱交換素子４を通過して、内気吹出口５を介して、また発熱体収納箱Ｂ内に戻る循環される内気風路６を形成している。 The air in the heating element storage box B (hereinafter referred to as “inside air”) is taken into the turbo fan 15 of the inside air blower 3 from the inside air suction port 2, passes through the heat exchange element 4, and passes through the inside air outlet 5. And the inside air passage 6 that is circulated back to the heating element storage box B is formed.
一方、外気吸込口７より外気送風機８のターボファン１５に取込まれた後、熱交換素子４を通過して外気吹出口９を介して、外気に排出する外気風路１０を形成している。 On the other hand, after being taken into the turbo fan 15 of the outside air blower 8 from the outside air inlet 7, the outside air air passage 10 is formed that passes through the heat exchange element 4 and is discharged to the outside air through the outside air outlet 9. .
熱交換素子４は略直方体であり、外気と内気の顕熱を交換し、外気風路１０と内気風路６の間に配置されている。 The heat exchange element 4 is a substantially rectangular parallelepiped, and exchanges sensible heat between the outside air and the inside air, and is disposed between the outside air passage 10 and the inside air passage 6.
また、内気送風機３と外気送風機８は、ターボファン１５の回転軸と空気吸込方向が平行、かつ内気送風機３と外気送風機８のそれぞれの吹き出し方向を熱交換素子４の長手側風路の吸込口と一致するように配置されており、内気送風機３と外気送風機８の動作を制御する制御装置１３を備えている。 In addition, the inside air blower 3 and the outside air blower 8 have the rotation axis of the turbo fan 15 and the air suction direction parallel to each other, and the blowing directions of the inside air blower 3 and the outside air blower 8 are the suction ports of the long side air passage of the heat exchange element 4. And a control device 13 that controls the operation of the inside air blower 3 and the outside air blower 8.
箱体１の面に配される内気吹出口５及び外気吹出口９が、ともに熱交換素子４の内気側吹出口１６及び外気側吹出口（図示省略）と、面で接し一体となるように配置している。 The inside air outlet 5 and the outside air outlet 9 arranged on the surface of the box 1 are both in contact with and integrated with the inside air outlet 16 and the outside air outlet (not shown) of the heat exchange element 4. It is arranged.
上記構成により、発熱体収納箱冷却装置Ａは、内気温度が外気温度のよりも低いときに外気を取り入れ、発熱体収納箱Ｂ内の暖かい空気との間で熱交換素子４にて熱交換をおこ
ない、暖かくなった外気は排気し、冷たくなった空気を発熱体収納箱Ｂ内に給気することにより、発熱体収納箱Ｂ内温度は低下する。
With the above configuration, the heating element storage box cooling device A takes in outside air when the inside air temperature is lower than the outside air temperature, and exchanges heat with the warm air in the heating element storage box B by the heat exchange element 4. When the outside air that has become warm is exhausted and the cooled air is supplied into the heating element storage box B, the temperature inside the heating element storage box B decreases.
また、冷却装置に送風するには熱交換素子４などが風路にあるため送風抵抗が大きいので遠心式送風機を用いており、発熱体収納箱冷却装置Ａの奥行きは、風量すなわちターボファン１５の径により決定されるため、ターボファン１５の径が大きくなった場合は、前記奥行きは変わらないため、遠心送風機は、薄型となる。 Further, since the heat exchange element 4 and the like are in the air path for blowing air to the cooling device, the air blowing resistance is large, so a centrifugal blower is used. The depth of the heating element storage box cooling device A is determined by the air flow, that is, the turbo fan 15. Since it is determined by the diameter, when the diameter of the turbo fan 15 increases, the depth does not change, so that the centrifugal fan becomes thin.
また、１つの発熱体収容箱冷却装置Ａの内気送風機３または外気送風機８が故障したときでも、他の発熱体収容箱冷却装置Ａが冷却機能を保持しており、すべての発熱体収容箱冷却装置Ａが同時に故障する可能性は低く、冷却機能が完全に喪失されることはない。 Even when the inside air blower 3 or the outside air blower 8 of one heating element housing box cooling device A breaks down, the other heating element housing box cooling devices A hold the cooling function, and all the heating body housing box coolings are performed. Device A is unlikely to fail at the same time and the cooling function is not completely lost.
また、内気吹出口５及び外気吹出口９と、熱交換素子４の内気側吹出口及び外気側吹出口の間のスペースが不要となり、発熱体収容箱冷却装置Ａの奥行きを薄型とすることができる。 Moreover, the space between the inside air outlet 5 and the outside air outlet 9 and the inside air side outlet and the outside air side outlet of the heat exchange element 4 becomes unnecessary, and the depth of the heating element housing box cooling device A may be reduced. it can.
なお、内気送風機３と外気送風機８にターボファン１５を用いて説明したが、別種のファンでもよい。 In addition, although the internal air blower 3 and the external air blower 8 were demonstrated using the turbo fan 15, another kind of fan may be used.

熱交換素子４からの内気を吹出す吹出口の周囲の吹出口外隅と箱体１の外気吹出口９の周囲の外気吹出口外隅および内気吹出口５の周囲の内気吹出口外隅の間の空間に、加算された合計の厚さが前記空間よりも数ｍｍ程度大きい、硬度が比較的高い、例えばポリエチレンのような断熱材Ａ４２、硬度が比較的低い、例えばエプトシーラーのような断熱材Ｂ４３をそれぞれの吹出口の開口に沿って層状に配し、構成する。また、外気吹出口９および内気吹出口５の四隅に位置する最隅部は４５°程度の傾斜形状としておき、前記断熱材Ａ４２、断熱材Ｂ４３も傾斜形状に沿って層状に配する。 Outer corners around the blower outlet that blows out the internal air from the heat exchange element 4, the outer corners around the outside air outlet 9 of the box 1, and the outer corners around the inside air outlet 5. In the space between, the total thickness added is about several millimeters larger than the space, the hardness is relatively high, for example, a heat insulating material A42 such as polyethylene, the hardness is relatively low, for example, a heat insulating material such as ept sealer B43 is arranged in a layered manner along the opening of each outlet. In addition, the outermost air outlet 9 and the inner air outlet 5 are located at the four corners of the outermost corner with an inclined shape of about 45 °, and the heat insulating material A42 and the heat insulating material B43 are also arranged in layers along the inclined shape.
上記構成により、熱交換素子４と外気吹出口９および内気吹出口５の間の空間に配した断熱材Ａ４２、断熱材Ｂ４３が各々異なる圧縮率で押しつぶれるため、例えばポリプロピレン等の樹脂で成形された熱交換素子４のような平坦度を均一にしにくい場合でも、空間を堅固に埋めることができる。また、吹出口は箱体１の面のたわみにより、熱交換素子４と箱体１の空間の大きさがばらつきやすいが、最隅部を４５°程度の傾斜形状とすることで、空間の最も大きくなる部分の面積を少なくすることができる。 With the above configuration, the heat insulating material A42 and the heat insulating material B43 disposed in the space between the heat exchange element 4 and the outside air outlet 9 and the inside air outlet 5 are crushed at different compression rates. Even when it is difficult to make the flatness uniform as in the case of the heat exchange element 4, the space can be firmly filled. In addition, the size of the space between the heat exchange element 4 and the box 1 is likely to vary due to the deflection of the surface of the box 1 at the air outlet. The area of the enlarged portion can be reduced.
空間を堅固に埋めることができると、熱交換素子４と外気吹出口９および内気吹出口５の間から外気に含まれる塵埃、雨水等の浸入防止が可能となる。 If the space can be firmly filled, it is possible to prevent intrusion of dust, rainwater and the like contained in the outside air from between the heat exchange element 4 and the outside air outlet 9 and the inside air outlet 5.

( Reference Example 11 )
Next, Reference Example 11 will be described with reference to FIG.
図１４は参考例１１における発熱体収納箱冷却装置の箱体とパネルの接続関連断面図を示したものである。以下、本実施の形態のパネルと箱体の取り付け構造について説明する。図１４において、図３と同じ構成要素については同じ符号を用い、説明を省略する。 FIG. 14 shows a connection-related cross-sectional view of the box and panel of the heating element storage box cooling device in Reference Example 11 . Hereinafter, the panel and box attachment structure of the present embodiment will be described. 14, the same components as those in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted.
パネル３０を箱体１へ取り付ける開口部分（箱体の一つの面の開口部全周部分）である箱体開口端部１ｄについて、以下、代表して底面側の一端において説明する。発熱体収納箱冷却装置Ａを構成する箱体１は、例えば鋼板を用いて、底面から箱体開口端部１ｄを支点として鋭角に曲げられた箱体第一曲げ部１ａと、箱体第一曲げ部１ａの箱体開口端部１ｄと反対の端部を支点に取り外し可能なパネル３０（以下、これをパネル３０と称する）の平面部とほぼ平行な角度に曲げられた箱体第二曲げ部１ｂと、箱体第二曲げ部１ｂの箱体第一曲げ部１ａと反対の端部を支点に、パネル３０にほぼ垂直な角度に曲げられて形成される箱体第三曲げ部１ｃで構成される。箱体第三曲げ部１ｃのパネル３０側端部は、箱体開口端部１ｄから見て、パネル３０の板厚分とさらに数ｍｍ短くしておく。また、箱体第二曲げ部１ｂの平坦部には、例えばポップナット４７を備える。 The box opening end 1d, which is an opening for attaching the panel 30 to the box 1 (the entire circumference of the opening on one surface of the box), will be described below at one end on the bottom side as a representative. The box 1 constituting the heating element storage box cooling apparatus A includes, for example, a steel box, a box first bent portion 1a bent from the bottom surface at an acute angle with the box opening end 1d as a fulcrum, and a box first A second bent box body bent at an angle substantially parallel to a plane portion of a panel 30 (hereinafter referred to as a panel 30) that can be removed with the end portion of the bent portion 1a opposite to the box opening end portion 1d as a fulcrum. A box body third bent portion 1c formed by being bent at an angle substantially perpendicular to the panel 30 with an end portion of the box body second bent portion 1b opposite to the box body first bent portion 1a as a fulcrum. Composed. The panel 30 side end of the box third bent portion 1c is made a few mm shorter than the thickness of the panel 30 as viewed from the box opening end 1d. Moreover, the pop nut 47 is provided in the flat part of the box body 2nd bending part 1b, for example.
前記ポップナット４７は、溶接ナット、バーリングタップでもかまわない。 The pop nut 47 may be a welding nut or a burring tap.
一方、パネル３０は、箱体１の底面側端部を箱体第一曲げ部１ａと平行もしくは箱体第一曲げ部１ａの平面に向かうように、２〜３°傾斜をつけて曲げられる。箱体１とパネル３０は、ねじ４５を介して、箱体第二曲げ部のポップナット４７に接続されるが、パネル３０のパネル曲げ部３０ａの端部に水や空気に対してシール性能を有する第一の断熱材４８を配する。また、パネル３０には、箱体第三曲げ部１ｃに接触する部分に水や空気に対してシール性能を有する第二の断熱材４９を配する。 On the other hand, the panel 30 is bent with an inclination of 2 to 3 ° so that the bottom side end of the box 1 is parallel to the box first bent portion 1a or toward the plane of the box first bent portion 1a. The box 1 and the panel 30 are connected to the pop nut 47 of the box second bent portion via the screw 45, but the end portion of the panel bent portion 30a of the panel 30 has a sealing performance against water and air. The 1st heat insulating material 48 which has is arranged. In addition, the panel 30 is provided with a second heat insulating material 49 having a sealing performance against water and air at a portion in contact with the box third bent portion 1c.
なお、第一の断熱材４８は箱体第一曲げ部１ａ側の平面上に、第二の断熱材４９は箱体第三曲げ部１ｃの先端に配してもよい。 In addition, the 1st heat insulating material 48 may be distribute | arranged on the plane by the side of the box 1st bending part 1a, and the 2nd heat insulating material 49 may be distribute | arranged to the front-end | tip of the box 3rd bending part 1c.
ねじ４５には、パネル３０の裏側空間に位置させて内歯状の座金４６をあらかじめ設けておき、ねじ４５を前記ポップナット４７に締結してパネル３０を箱体１へ取り付けるも
のである。そして、箱体第二曲げ部１ｂとパネル３０の間に箱体第三曲げ部１ｃの長さで形成した奥行きを持つ空間が形成されて、内歯状の座金４６は前記空間内に自由な位置に配されることになる。
An internal toothed washer 46 is provided in advance on the screw 45 in the space behind the panel 30, and the screw 45 is fastened to the pop nut 47 to attach the panel 30 to the box 1. A space having a depth formed by the length of the box third bent portion 1c is formed between the box second bent portion 1b and the panel 30, and the internal toothed washer 46 is free in the space. Will be placed in position.
座金４６の材質は、鋼板等の金属でもよいが、ねじ山を傷つける恐れがあるため、ナイロン等の樹脂を用いるのが望ましい。 The material of the washer 46 may be a metal such as a steel plate, but it is desirable to use a resin such as nylon because it may damage the thread.
上記構成により、ねじ４５を締め付けてパネル３０を箱体１に固定するときは、箱体第一曲げ部１ａを鋼板で形成することによって可能となるばねの性質（弾性）により、箱体第一曲げ部１ａを支点に、箱体第三曲げ部１ｃとパネル３０は互いに引き合うい、第二の断熱材４９を押しつぶしながら、互いに密着する。また、箱体第一曲げ部１ａとパネル３０のパネル曲げ部３０ａにも同様に、互いに引き合う力が働き、第一の断熱材４８を押しつぶしながら、互いに密着する。 With the above configuration, when the panel 45 is fixed to the box body 1 by tightening the screws 45, the box body first is made possible by the nature (elasticity) of the spring that is made possible by forming the box body first bent portion 1a with a steel plate. With the bent portion 1a as a fulcrum, the box third bent portion 1c and the panel 30 are brought into close contact with each other while being crushed by the second heat insulating material 49. Similarly, a force attracting each other acts on the box first bent portion 1 a and the panel bent portion 30 a of the panel 30, and the first heat insulating material 48 is crushed and is in close contact with each other.
また、ねじ４５を緩めてパネル３０を箱体１から外すときは、ポップナット４７からねじ４５が外れた後も、箱体第二曲げ部１ｂとパネル３０の空間があるために、座金４６がねじ４５に留まるため、ねじ４５がパネル３０から落下しない。 Further, when the screw 45 is loosened and the panel 30 is removed from the box 1, the washer 46 is removed because the space between the box second bent portion 1 b and the panel 30 exists after the screw 45 is removed from the pop nut 47. Since the screw 45 remains, the screw 45 does not fall from the panel 30.
奥行きを薄型にする送風機の回転軸と空気吸込方向が平行となる配置の場合には、外気を取り入れるときに浸入する塵埃、雨水等が外気風路を形成する壁面に飛散し、特に取り外し可能なパネル３０から浸入する可能性が高まるが、箱体第一曲げ部１ａ、箱体第二曲げ部１ｂ、箱体三曲げ部１ｃ、第一の断熱材４８、第二の断熱材４９を組み合わせてねじ４５によりパネル３０を箱体１へ締結する二重に遮断する手段により、二重かつ堅固に密着できる構造なので、塵埃、雨水等の浸入防止ができる。 In the case where the rotation axis of the blower that makes the depth thin and the air suction direction are parallel, dust, rainwater, etc. that enter when taking in outside air scatters on the wall surface that forms the outside air passage, and is especially removable Although the possibility of entering from the panel 30 is increased, the box first bent portion 1a, the box second bent portion 1b, the box three bent portion 1c, the first heat insulating material 48, and the second heat insulating material 49 are combined. With the structure that allows the panel 30 to be tightly and firmly adhered to the box body 1 by the screws 45, the dust can be prevented from entering.
また、メンテナンス時にねじ４５を緩めてパネル３０を外すときに、パネル３０からねじ４５の落下が防止できる。 Further, when the panel 45 is removed by loosening the screws 45 during maintenance, the screws 45 can be prevented from dropping from the panel 30.
（参考例１２）
次に、参考例１２について、図１６を参照しながら説明する。
( Reference Example 12 )
Next, Reference Example 12 will be described with reference to FIG.
図１５は参考例１４における発熱体収納箱冷却装置の構成図を示したものである。図１５において、図２、１０と同じ構成要素については同じ符号を用い、説明を省略する。 FIG. 15 shows a configuration diagram of the heating element storage box cooling device in Reference Example 14 . In FIG. 15, the same components as those in FIGS.
発熱体収納箱冷却装置Ａの内部において、制御装置１３は、２つの内気送風機３の中間かつ送風方向に配置され、制御装置１３の外気側壁面と箱体１の外気面の間に１０ｍｍ程度の空間を設け、内気送風機３が運転されるときには、大部分の空気が通過する熱交換素子４の吸込口に直接吸込まれる内気風路６と、前記空間を通過した後に、熱交換素子４に吸込まれる内気風路６を形成する。また、プリント基板３８を配したプリント基板固定板５０を制御装置１３の内気側面に設けた穴に差込んで、取り外し可能なパネル３０の側からねじで固定し、かつ前記放熱板３７に配したプリント基板３８に対して列状に並べて配置する。 Inside the heating element storage box cooling device A, the control device 13 is arranged between the two inside air blowers 3 and in the blowing direction, and is about 10 mm between the outside air side wall surface of the control device 13 and the outside air surface of the box 1. When a space is provided and the inside air blower 3 is operated, the inside air flow path 6 directly sucked into the suction port of the heat exchange element 4 through which most of the air passes, and the heat exchange element 4 after passing through the space The inside air path 6 to be sucked is formed. Further, the printed board fixing plate 50 on which the printed board 38 is arranged is inserted into a hole provided on the inside air side surface of the control device 13, fixed from the side of the removable panel 30 with a screw, and arranged on the heat radiating plate 37. They are arranged in a row with respect to the printed circuit board 38.
上記構成により、制御装置１３の外気側壁面と箱体１の外気面の間に、外気温度に比べて比較的高い内気風路の空気が流れる。また、２つの内気送風機３の中間に制御装置１３を配することで、一方の内気送風機３が故障したときにも、前記制御装置１３の外気側壁面と箱体１の外気面の間に、内気風路の空気が流れる。また、プリント基板３８を配したプリント基板固定板５０を制御装置１３の内気側面に設けた穴に差込んで取り外し可能なパネル３０側の制御装置１３の面に、ねじ４５で固定することで、プリント基板固定板５０の取り付け／取り外しが容易になる。 With the above-described configuration, the air in the inside air path that is relatively higher than the outside air temperature flows between the outside air side wall surface of the control device 13 and the outside air surface of the box 1. Further, by arranging the control device 13 in the middle of the two inside air blowers 3, even when one inside air blower 3 breaks down, between the outside air side wall surface of the control device 13 and the outside air surface of the box 1, Air from the inside air flow path flows. Also, by fixing the printed circuit board fixing plate 50 on which the printed circuit board 38 is arranged to the surface of the control device 13 on the panel 30 side which can be removed by being inserted into a hole provided in the inside air side surface of the control device 13, Attachment / removal of the printed board fixing plate 50 is facilitated.
制御装置１３の外気側壁面と箱体１の外気面の間に、外気温度に比べて比較的高い内気風路の空気が流れることで、制御装置１３の外気側壁面の結露防止が可能となり、電気的な安全が確保できる。また、２つの内気送風機３のうち、１つが故障したときにも、前記と同様の効果が維持できるので、結露防止が可能となり、電気的な安全が確保できる。また、取り外し可能なパネル３０側から、プリント基板固定板５０の取り付け／取り外しが容易になることで、メンテナンスを容易に行うことができる。 By allowing the air in the internal air path relatively higher than the outside air temperature to flow between the outside air side wall surface of the control device 13 and the outside air surface of the box 1, it becomes possible to prevent condensation on the outside air side wall surface of the control device 13. Electrical safety can be ensured. Further, even when one of the two inside air blowers 3 breaks down, the same effect as described above can be maintained, so that condensation can be prevented and electrical safety can be ensured. Further, since the attachment / detachment of the printed board fixing plate 50 is facilitated from the removable panel 30 side, maintenance can be easily performed.
