しかし、キャビネットラック底部に吸気ファンを設けたものは、特許文献1に記載されているように収納された機器が吸気する機器の前面側に向けて送風するため、風の当たる前面部の温度は効果的に下げることができるが、風の当たらない部分は逆に熱せられた空気(暖気)の回り込みや滞留等で局部的に温度が上昇する場合があった。
また、天板部に排気ファンを設けたものは、冷気と機器が排出した暖気が混ざりやすく、冷却効率が悪かったし、天井が低い環境では排気効率が低下し易かった。更に、コストの点から排気ファンはキャビネットラックの天板から突出して設けられるため、キャビネットラックの外観上好ましいものではなかった。但し、この天板部に排気ファンを設けた構成の場合、本出願人は特許文献3において空気の流れを分離する熱遮蔽板を設けることで、キャビネットラック内の冷気と暖気を分離する構成を提案しているが、天井が低い場合や見栄えの問題は相変わらず残っていた。
また、吸気ファン、排気ファンの双方を設けたものは、何れか一方を設けた構成に比べて排気効率がアップするが、コスト高であったし、見栄えの問題も引き続き発生していた。
However, in the case where the intake fan is provided at the bottom of the cabinet rack, the device stored as described in Patent Document 1 blows air toward the front side of the device to be sucked, so the temperature of the front portion where the wind hits is Although the temperature can be effectively lowered, the temperature of the portion not exposed to the wind may rise locally due to the wraparound or stay of heated air (warm air).
In addition, in the case where an exhaust fan is provided on the top plate portion, the cold air and the warm air exhausted by the equipment are easily mixed, the cooling efficiency is poor, and the exhaust efficiency is easily lowered in an environment where the ceiling is low. Furthermore, since the exhaust fan is provided so as to protrude from the top plate of the cabinet rack in terms of cost, it is not preferable in terms of the appearance of the cabinet rack. However, in the case of a configuration in which an exhaust fan is provided in the top plate portion, the present applicant has a configuration in which the cool air and the warm air in the cabinet rack are separated by providing a heat shield plate that separates the air flow in Patent Document 3. Proposal, but the problem of the appearance is still remained when the ceiling is low.
Moreover, although the exhaust fan is provided with both the intake fan and the exhaust fan, the exhaust efficiency is improved as compared with the structure provided with either one, but the cost is high and the appearance problem continues to occur.

そこで、本発明はこのような問題点に鑑み、簡易な構成で部分的な温度上昇を抑える事ができ、また天井が低くても外観を損なう事無く良好に排熱できるキャビネットラックを提供することを目的とする。   Therefore, in view of such a problem, the present invention provides a cabinet rack that can suppress a partial temperature rise with a simple configuration and can exhaust heat well without damaging the appearance even when the ceiling is low.

FIG. 1 is an explanatory side view showing an example of a cabinet rack (hereinafter simply referred to as a rack) according to the present invention. 1 is a rack having a box-like case and configured to be closed, and 2 is housed. 3 is a cooling device, and 4 is an exhaust part. The arrows indicate the outline of the air flow in the rack, the thick arrows A1 to A3 indicate the flow of cool air sucked from under the floor, and the thin arrows B1 to B3 indicate the flow of air discharged from the equipment and warmed.

ラック内の各機器2は、ケース内の左右に立設された図示しない一対のマウントフレームにボルト止めされて固定され、上下に隣接して収納されている。個々の機器2は後方に排気ファンを内蔵し、冷却のために前面から吸引された空気を後方に排気(矢印B2)するよう構成されている。   Each device 2 in the rack is bolted and fixed to a pair of mount frames (not shown) standing up and down in the left and right in the case, and is stored adjacent to the top and bottom. Each device 2 has a built-in exhaust fan at the rear, and is configured to exhaust air sucked from the front for cooling (arrow B2).

冷却装置3は、図2の外観図に示すように、四角形箱状のハウジング5を有し、内部に下方から外気を吸引するターボファン6を備えている。ハウジング5の4側面には吸引した冷気を噴き出す吹き出し口7が斜め上方に向けて設けられている。この吹き出し口7は、全て同一形状で形成され、夫々同量の冷気を噴き出すよう形成されている。尚、ラック1を設置した床面には冷気吸引用の吸気口が設けられている。
一方、排気部4はケースの天板1aに設けられた排気孔4aから成り、天板1aに複数穿設され、冷却装置3の外気吸引圧で暖められた空気が排気孔4aから外部に放出される。
As shown in the external view of FIG. 2, the cooling device 3 includes a rectangular box-shaped housing 5 and includes a turbo fan 6 that sucks outside air from below. On the four side surfaces of the housing 5, blowout ports 7 for blowing out the sucked cold air are provided obliquely upward. The blowout ports 7 are all formed in the same shape, and are formed so as to blow out the same amount of cold air. Note that an air inlet for cold air suction is provided on the floor surface on which the rack 1 is installed.
On the other hand, the exhaust section 4 is composed of exhaust holes 4a provided in the top plate 1a of the case. A plurality of holes are formed in the top plate 1a, and the air heated by the outside air suction pressure of the cooling device 3 is discharged from the exhaust holes 4a to the outside. Is done.

このように構成された冷却装置3を設けることで、ラック1内には以下のような空気の流れが生ずる。冷却装置3により吸引された冷気は、矢印A1に示すようにラック1下部においてハウジング5の四方から斜め上方に向けて放出され、機器2の周囲に向けて噴き出される。そのうち前方に放出された冷気は、図1の矢印A2に示すように、上方にスムーズに流れて行き、途中で個々の機器2に吸引されて冷却に寄与する。
