JP-A-5-335765 Japanese Patent Laid-Open No. 11-63547 JP 2001-257495 A

上記した従来の筐体の冷却構造においては、冷却空気は図３（ｂ）の矢印に示すように流れるが、筐体１の内部に流れ込まない空気も多く、またフロントパネル２には高発熱コネクタ９，１０や表示機器１５等が設けられているので、吸気口１１，１２の面積を増大させることも限度があり、吸気口１１〜１３や排気口１４の面積を多少増大させても冷却効果はあまり上がらず、冷却効果を上げることは困難であった。   In the conventional casing cooling structure described above, the cooling air flows as shown by the arrow in FIG. 3B, but there is much air that does not flow into the casing 1, and the front panel 2 has a high heat generating connector. 9, 10 and the display device 15 are provided, so there is a limit to increasing the area of the intake ports 11 and 12, and the cooling effect can be achieved even if the areas of the intake ports 11 to 13 and the exhaust port 14 are increased somewhat. It was difficult to increase the cooling effect.

この発明は上記のような課題を解決するために成されたものであり、冷却効率を向上するとともに、小型化が可能な筐体の冷却構造を得ることを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain a cooling structure for a casing that can be reduced in size while improving cooling efficiency.

この発明の請求項１に係る筐体の冷却構造は、フロントパネルに、複数の吸気口を上下に並べ、かつ上側の吸気口の真下から水平方向にずらした位置に下側の吸気口を設けるとともに、天井板に排気口を設け、前記各吸気口に臨んでプリント板を収納した筐体において、前記プリント板の前端側には発熱コネクタを設け、該発熱コネクタを前記吸気口の下側から前記フロントパネルの前面に突出させるとともに、前記フロントパネルの上端に、フロントパネルの前方に突出して冷却風を前記吸気口に導くひさしを設けたものである。 According to a first aspect of the present invention, a cooling structure for a housing is provided with a plurality of intake ports arranged vertically on the front panel , and provided with a lower intake port at a position shifted horizontally from directly below the upper intake port. under with the exhaust port is provided on the top plate, the housing accommodating the printed circuit board facing the respective intake ports, provided fever connector on the front side of the printed circuit board, the heat generating connector of the intake port In addition to projecting from the side to the front surface of the front panel, an eaves projecting forward of the front panel and guiding cooling air to the intake port is provided at the upper end of the front panel.

以上のようにこの発明の請求項１によれば、フロントパネルの上端に前方に突出したひさしを設けており、従来上方に流れていた冷却風がひさしに遮られてフロントパネルの吸気口から筐体内に流入するようになり、冷却効率が向上する。又、吸気口や排気口をあまり大きくしなくても良いので、小型化が可能となる。   As described above, according to the first aspect of the present invention, the eaves projecting forward are provided at the upper end of the front panel, and the cooling air that has been flowing upward is blocked by the eaves so that it can be opened from the intake port of the front panel. It begins to flow into the body, improving the cooling efficiency. Further, since it is not necessary to make the intake port and the exhaust port so large, the size can be reduced.

実施最良形態１
以下、この発明を実施するための最良の形態を図面とともに説明する。図１（ａ），（ｂ）はこの発明の実施最良形態１による筐体の冷却構造の斜視図及びそのＢ−Ｂ線縦断側面図を示し、筐体１のフロントパネル２の上端には前方に突出してひさし１６を設ける。その他の構成は従来と同様である。 Best Embodiment 1
The best mode for carrying out the present invention will be described below with reference to the drawings. FIGS. 1A and 1B are a perspective view of a cooling structure for a housing according to the first embodiment of the present invention and a vertical side view taken along line B-B. The eaves 16 are provided so as to protrude from the surface. Other configurations are the same as those of the prior art.

上記構成において、図１（ｂ）に矢印で示すように、フロントパネル２の吸気口１１，１２においては、上昇した空気はひさし１６により遮られ、吸気口１１，１２から筐体１内に流入する。このため、冷却空気の流通量が増大し、冷却効率が向上する。又、吸気口１１及び排気口１２をあまり大きくしなくても、冷却空気の流通量が得られるので、筐体１の小型化が可能となる。   In the above configuration, as shown by arrows in FIG. 1B, the air that has risen is blocked by the eaves 16 at the intake ports 11 and 12 of the front panel 2 and flows into the housing 1 from the intake ports 11 and 12. To do. For this reason, the circulation amount of the cooling air is increased, and the cooling efficiency is improved. Further, since the amount of cooling air can be obtained without enlarging the intake port 11 and the exhaust port 12, the housing 1 can be downsized.

実施最良形態２
図２（ａ），（ｂ）は実施最良形態２による多段筐体の冷却構造の正面図及び側面図を示し、１は従来同様の筐体であり、フロントパネル２に吸気口１１，１２を有するとともに、側板３に吸気口１３を有する。又、天井板５に排気口１４を有し、内部にはプリント板６，７等の電子機器を有する。二つの筐体１の取付ブラケット４を取付枠１７にボルト１８により取り付けるが、二つの筐体１は上下に間隔をあけて取り付ける。この結果、多段筐体が構成される。又、各筐体１のフロントパネル２の上端位置において前方に突出するようにしてひさし兼用のケーブルダクト１９を取付枠１７にボルト２０により取り付ける。ケーブルダクト１９には筐体１毎にケーブル２１を支持する。 Embodiment 2
FIGS. 2A and 2B are a front view and a side view of a cooling structure for a multistage housing according to the second embodiment. In addition, the side plate 3 has an intake port 13. Further, the ceiling plate 5 has an exhaust port 14, and electronic devices such as printed boards 6 and 7 are provided inside. The mounting brackets 4 of the two housings 1 are attached to the mounting frame 17 with bolts 18, and the two housings 1 are attached at intervals in the vertical direction. As a result, a multistage housing is configured. Further, a cable duct 19 serving as an eaves is attached to the attachment frame 17 with a bolt 20 so as to protrude forward at the upper end position of the front panel 2 of each housing 1. The cable duct 19 supports a cable 21 for each housing 1.

上記構成において、冷却風は吸気口１１〜１３から吸入され、排気口１４から排出されるが、ひさし兼用のケーブルダクト１９を設けたことにより吸気口１１，１２の外側を上方に流れていた冷却風がケーブルダクト１９に遮られて吸気口１１，１２から筐体１内に流入するようになり、冷却空気の流通量が増大して冷却効果が向上する。又、吸気口１１〜１３や排気口１４をあまり大きくする必要がなく、筐体１を小型化することができる。 In the above structure, cooling air is sucked from the air suction port 11 to 13, is discharged from the exhaust port 14, it has been flowing in the outer air inlet 11 and 12 upward by providing the cable duct 19 of the eaves combined The cooling air is blocked by the cable duct 19 and flows into the housing 1 from the air inlets 11 and 12, and the amount of cooling air flowing is increased, thereby improving the cooling effect. In addition, the air intake ports 11 to 13 and the exhaust port 14 so there is no need to increase, the housing 1 can be reduced in size.
