Abstract

<P>PROBLEM TO BE SOLVED: To provide a small-size and lightweight electronic apparatus through reduction in size of a heatsink, by improving the cooling effect of electronic components generating a large amount of heat arranged on a substrate. <P>SOLUTION: A wind-shield cover 6 is provided with a intake port 4 formed of a first opening 4-1 which is lower than the height of a cooling fin 3 of the heatsink 1 to intake the cooling wind, and a second opening 4-2 which is almost equal to the height of the cooling fin 3. This wind-shield cover 6 is mounted to the external side of the heatsink 1 in which a plurality of cooling ins 3 are formed. The electronic components 5-2 which generate a large amount of heat among a plurality of electronic components are arranged so that these components are cooled with the cooling wind generated by a fan 7 from the second opening 4-1. Since the fan sends a large amount of wind in the side of the second opening 4-1, effective cooling is realized by arranging the electronic components 5-2 which generate a large amount of heat in the side of the second opening 4-1 which provides a large amount of wind. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明は、例えば、通信機の送信部などで用いられる増幅器や発信器、変調器等が基板に配置された電子装置に関し、特に、トランジスタ等の発熱量が大きい電子部品が配置されたときに、効率的に冷却を行う電子装置に関するものである。
【0002】
【従来の技術】
従来の複数の発熱部品を空気冷却する電子装置では、図5に示すように、例えばアルミニュウム合金製の複数の冷却用のフィン500で形成したヒートシンク501の基板502に電子部品503を実装することにより放熱を行っていた。
【0003】
また、発熱部品を実装したヒートシンクに対して、冷却風を効率的にあてるために、冷却風の風上側のヒートシンクに設けられているフィンやピンの一部を削除し、フィンやピンを削除した部分を設けた側に発熱量の大きい電子部品を実装することが考えられている。
【0004】
また、放熱フィンを有する放熱体の上面にプリント基板を設け、フィンと基板に搭載された増幅器などの能動素子の放熱用ベースプレートを放熱体に固定したときに、プリント基板と放熱体との間に、冷却用の通風経路となる空隙を設けて対流による放熱構造を用いた電子回路装置が開示されている(例えば、特許文献1参照。)。

また、ファンを用いた電子機器の冷却構造として、放熱器に送風してして冷却するファンの排気口に絞り形状のフードを設けることにより、冷却用のファンの送風能力を充分に利用して、冷却効果を増大させる電子機器の冷却構造が開示されている(例えば、特許文献2参照。)。

【0008】
【発明が解決しようとする課題】
しかしながら、上記従来の技術では、電子部品の発熱を効率的に放熱するためには、ヒートシンクに大きな放熱面積が必要となり、ヒートシンクの大型化、重量化してしまい、近年の小型化及び軽量化の要求に沿うことができないという問題点があった。
【0009】
また、冷却風を効率的にあてるために、フィンやピンを削除する構造では、フィンやピンを削除した部分は、極めて冷却効果が低下するため、電子部品の配置に制約が生じるため、装置の大型化に繋がるという問題点があった。
【0010】
本発明は、上記問題点を解決するために鑑み為されたものであり、発熱量の大きい電子部品に対する冷却効果を高めることにより、ヒートシンクを小型化することで、装置全体を小型、軽量化する電子機器を提供することを目的とする。
【0011】
【課題を解決するための手段】
本発明は、上記目的を達成するために、複数の冷却フィンが形成されたヒートシンクの外側に風洞カバーを設け、この風洞カバーに、冷却風を吸入するためのヒートシンクの冷却フィンの高さより低い第1の開口部と前記冷却フィンの高さと略同一の高さの第2の開口部からなる吸入口を設けて、この第2の開口部のファンにより発生される冷却風の下流側に、前記複数の電子部品のうち発熱量が大きい電子部品を配置することにより、第1の開口部の下流側ではファンによる風量が少なくなり、第2の開口部の下流側ではファンによる風量が多くなるため、この風量が多くなる第2の開口部の下流側に、配置した発熱量の多い電子部品を効率的に冷却することができる。
【0012】
また、本発明は、上記目的を達成するために、複数の冷却ピンが形成されたヒートシンクの外側に風洞カバーを設け、この風洞カバーに、冷却風を吸入するためのヒートシンクの冷却ピンの高さより低い第1の開口部と前記冷却ピンの高さと略同一の高さの第2の開口部からなる吸入口を設けて、この第2の開口部のファンにより発生される冷却風の下流側に、前記複数の電子部品のうち発熱量が大きい電子部品を配置することにより、第1の開口部の下流側ではファンによる風量が少なくなり、第2の開口部の下流側ではファンによる風量が多くなるため、この風量が多くなる第2の開口部の下流側に、配置した発熱量の多い電子部品を効率的に冷却することができる。
【0013】
【発明の実施の形態】
本発明の一実施の形態の第1の実施例を図1〜図3を用いて説明する。図1は本発明の第1の実施例の電子機器の外観図、図2は本発明の第1の実施例の電子機器の分解図、図3は本発明の第1の実施例の電子機器の側面図をそれぞれ示している。
【0014】
図中1はヒートシンク、2は基板、3は冷却フィン、4は吸入口、5−1は発熱量の小さい電子部品、5−2は発熱量の大きい電子部品、6は風洞カバー、7はファンである。
【0015】
上記ヒートシンク1は、基板2を取付ける面と、その反対面に放熱用のフィン3が形成されている。尚、このヒートシンク1は、銅やアルミニウム合金等で構成され、軽量が要求される場合には、Mg合金が使用されるが、これらに限定されるものではない。
【0016】
このヒートシンク1には、風洞カバー6が取付けられ、この風洞カバー6は、吸入口4からフィン3を通過するまで、冷却風が外に漏れないように構成し、この風洞カバー6の一端に冷却風を発生させるためのファンが取り付れる構造となっている。
【0017】
本発明の電子機器では、図2に示すように、ファン7が回転すると、吸入口4からファン7の方向に冷却風が発生され、ヒートシンク1の冷却フィン3が、この冷却風で冷却されることにより、電子部品が冷却される構造となっていおり、ファン7は、ヒートシンク1の下流側に、冷却フィン3の後端から十分な距離をもって配置されている。 また、本発明では、本発明では、2つの冷却ファンを用いているが、その数は2つに限定されるものでなく、装置の大きさいに応じて、適宜冷却ファンの数を増減させて設ければ良い。
【0018】
また、上記吸入口4は、冷却フィン3の高さより低い開口部(以下、第1の開口部とする)4−1と、冷却フィンの高さと略同一の高さの開口部(以下、第2の開口部とする)4−2とから構成され、第1の開口部4−1での圧力損失は、第2の開口部4−2より大きくなる。
【0019】
すなわち、第1の開口部4−1とファン7との間での冷却風の流量は少なくり、第2の開口部4−2とファン7との間での冷却風の流量は多くなるため、第1の開口部4−1の下流側に、発熱量の小さい電子部品5−1を配置し、第2の開口部4−2の下流側に、発熱量の大きい電子部品5−2を配置することより、効果的に冷却することができるようになる。
【0020】
また、吸入口4の第1の開口部4−1と第2の開口部4−2とは、電子部品全体の配置を考慮して、自由に設定することができる。
上記発熱量の大きい電子部品5−2としては、例えば、トランジスタや電界効果トランジスタ等の高電力半導体能動素子等があるが、これらに限定されるものではない。
【0021】
また、従来のように、冷却フィンを削除する必要がないため、極めて冷却能力が低下する部分がないため、ヒートシンクを小型化することができるため、装置全体を小型、軽量化することができる。
【0022】
次に、本発明の一実施の形態の第2の実施例を図4を用いて説明する。図4は本発明の第2の実施例の電子機器の分解図を示す図である。第2の実施例は、上記第1の実施例のヒートシンク1の構造が異なり、ヒートシンク8に冷却ピン8を形成したものであり、その他の構造は、上記第1の実施例と同様である。
【0023】
本発明の実施例2では、上記実施例1と同様に、ファン7が回転すると、吸入口4からファン7の方向に冷却風が発生され、ヒートシンク8の冷却ピン9が、この冷却風で冷却されることにより、電子部品が冷却される構造である。
【0024】
また、上記第1の実施例と同様に、吸入口4を第1の開口部と4−1と第2の開口部4−2とから構成することにより、第1の開口部4−1とファン7との間での冷却風の流量は少なくり、第2の開口部4−2とファン7との間での冷却風の流量は多くなるため、第1の開口部4−1の下流側に、発熱量の小さい電子部品5−1を配置し、第2の開口部4−2の下流側に、発熱量の大きい電子部品5−2を配置することより、効果的に冷却することができるようになる。
【0025】
本発明の第2の実施例では、上記第1の実施例の冷却フィン3を冷却ピン9にすることにより、ヒートシンクを更に軽量化することができる。
【0026】
【発明の効果】
以上説明したように、本発明では、冷却風の吸入口に、冷却フィン又は冷却ピンの高さより低い開口部と、冷却フィン又は冷却ピンの高さと略同一の高さの開口部とで構成することにより、冷却フィン又は冷却ピンの高さより低い開口部とファン7との間での冷却風の流量は少なくり、冷却フィン又は冷却ピンの高さと略同一の高さの開口部とファン7との間での冷却風の流量は多くなるため、冷却フィン又は冷却ピンの高さと略同一の高さの開口部の下流側に、発熱量の大きい電子部品5−2を配置することより、効果的に冷却することができるようになるという効果を奏する。
【0027】
また、冷却効率が向上することにより、ヒートシンクを小型化することが可能となり、電子機器全体を小型、軽量化することができるという効果を奏する。

A suction port comprising a low first opening and a second opening having a height substantially equal to the height of the cooling pin is provided on the downstream side of the cooling air generated by the fan of the second opening. By disposing an electronic component that generates a large amount of heat among the plurality of electronic components, the airflow by the fan is reduced on the downstream side of the first opening, and the airflow by the fan is increased on the downstream side of the second opening. Therefore, the electronic component with a large calorific value arranged on the downstream side of the second opening where the air volume increases can be efficiently cooled.
[0013]
