Abstract
Description
本発明に係るファンシャーシは、壁パネルと、前記壁パネルの上端に接続される上パネル及び前記壁パネルの下端に接続される下パネルとを備える。前記壁パネルと前記上パネルと前記下パネルとの断面は、略U字状である。前記壁パネルは、ファンの取付穴に挿入される複数の突起を有する。前記上パネル及び前記下パネルの少なくとも一方は、前記ファンの上端部又は下端部が嵌合される貫通孔を有する。前記上パネルと前記下パネルとの間の内寸法は、前記ファンの上下方向の外形寸法よりも短い。前記上パネルと前記下パネルは、前記上パネルと前記下パネルとが互いに離間する方向に弾性変形する。
図1に示すように、本実施形態のファンユニット1は、無線通信システムの室内ユニットの通信装置30に組み込まれている。通信装置30は、筐体31と、複数の通信ユニット32と、プリント基板40と、2つのファンユニット1と、電源ユニット33と、フィルタ34を有する。筐体31は、直方体形状である。複数の通信ユニット32は、筐体31に搭載される。プリント基板40は、例えば制御基板である。
図2に示すように、筐体31の奥部にはマザーボード38が配置されている。通信ユニット32、プリント基板40、ファンユニット1、及び電源ユニット33は、マザーボード38上のMBコネクタ39を介して接続される。ファンユニット1は、このような通信機器に使用することに限られない。ファンユニット1は、サーバ装置やPC等の電子機器の機器内部の温度上昇を防ぐために使用することができる。
ファンユニット1は、筐体31内部から空気を引き抜き、通風穴36から空気を排出するように構成されている。フィルタ34はファンユニット1の空気排出に伴い、筐体31の内部に流入する空気に含まれる埃、塵などを遮断するように構成されている。
ファン本体3は、一面17から他面18に向かって風力を発生させるように構成されている。
基板部41は絶縁体基材からなるプリント基板である。基板部41は、長方形状であり、ファンシャーシ2の平面視形状と略同形状を有している。基板部41には、2つのファン本体3との干渉を避けるための2つの切欠部44が形成されている。
基板部41の左右方向の一辺の反対側の他辺には、3つの第二突片(第二突起部)46が形成されている。第二突片46は、後述するファンシャーシ2の第二差込部51に差し込まれる。
基板部41の後端には、左右方向に突出する第三突片(第三突起部)47が形成されている。第三突片47は、後述するファンシャーシ2の第三差込部53に挿入される。
制御コネクタ5は、基板部41の後端に設けられている。制御コネクタ5は接続部が後方を向くように取り付けられている。よって、ファンユニット1をスロット37に対して挿入し、マザーボード38(図2参照)に突き当てることによって、マザーボード38上のコネクタ39とファンユニット1の制御コネクタ5とが接続される。
前面パネル11の所定位置には、雌ねじ孔15が形成されている。この雌ねじ孔15には、ツマミねじ16(図3参照)が取り付けられる。このツマミねじ16が筐体31に設けられた板片(不図示)のねじ穴に螺合することによって、ファンユニット1は通信装置30の筐体31に固定される。
上パネル13には、2つのファン貫通孔21が形成されている。ファン貫通孔21の奥行方向の長さは、ファン本体3の幅と略同一である。ファン貫通孔21の左右方向の長さは、ファン本体3の厚さと略同一である。つまり、各々のファン貫通孔21の平面視形状は、ファン本体3のケーシング6の平面視形状と略同一である。
第一爪27は、ファン本体3を収容した際、ファン本体3のケーシング6のリブ19を下方から押圧する。第二爪28の先端部は、ファン本体3を収容した際、ファン本体3のケーシング6のリブ19の内側の側面に係止する。
まず、図12に示すように、ファンシャーシ2の右方より2つのファン本体3を挿入する。この際、上パネル13と下パネル14とを離間させるように、押し広げることによって、ケーシング6のリブ19とファンシャーシ2との干渉を回避させる。ファン本体3の他面18が壁パネル12と当接する位置まで押し込んだ後、押し広げを解除する。これにより、ファン本体3は壁パネル12により左方向への移動が拘束されるとともに、ファン貫通孔21により右方向への移動が拘束される。
例えば、図15に示すように、上パネル13に加えて下パネル14にもファン貫通孔21Bを設ける構成としてもよい。この構成においては、ファン本体3は、上下のファン貫通孔21,21B、及び突起24によって移動を拘束される。
この実施形態によれば、ファンユニット1の最大外形高さをファン本体3の最大外形と略同一にすることができる。このため、更なるファンユニットの小型化が容易となる。
