【発明の属する技術分野】
本発明は、放熱器を備えた電源装置に関する。
【０００２】
【発明が解決しようとする課題】
一般に、従来の電源装置では発生した熱を外部に放熱するため、熱を発する発熱部に放熱器を一体に取り付けている。その放熱器としては、例えば、冷却ファンと放熱用リブを有し強制空冷によるもの（特開平６−３８５４６号公報）や、冷却ファンを用いずに自然空冷によるものや、パイプに液体を流して温度を一定に保つもの（特開平６−２３００１２号公報）などがある。
【０００３】
しかし、上記のものはいずれも発熱部に放熱器が組み込まれ、該放熱器が電源ユニットに固定装備されているため、電源ユニットの重量が増加し、使用条件に合わせて放熱効果を大きくするためには放熱器自体も大型となり、このため負荷装置への装着にもスペースを要し、取付構造も大掛かりとなって、コストアップを招くという問題がある。また、負荷装置にスロットインにより着脱するタイプのものでは、電源装置が重たくなると、その取付作業が繁雑となる。そして、保守点検時に、寿命に至った電源は交換され、この際、使用可能な放熱器も電源とともに破棄されていた。
【０００４】
そこで、本発明は上記問題点を解決して、放熱器を無駄なく継続して使用でき、資源の節約が可能な電源装置を提供し、加えて、取付作業性に優れた電源装置を提供することを目的とする。
【０００５】

【００１４】

【００１５】
【発明の実施形態】
以下、添付図面に基づき、本発明における電子機器の各実施例を説明する。図１〜図４は、本発明の第１実施例を示し、同図に示すように、電源装置１は、電源ユニット２と、この電源ユニット２を取り付ける取付部材３と、この取付部材３に回動可能に設けた放熱器４とを備え、前記電源ユニット２は発熱部５を有し、前記取付部材３を負荷装置などの固定部たる固定側取付部６に固定している。前記取付部材３は、スライド挿入部たるガイドレール７，７を対向して備え、これらガイドレール７，７間に前記電源ユニット２の両側のスライド縁２Ｆ，２Ｆが着脱可能に挿入される。尚、ガイドレール７，７の基端側は連結部材７Ａにより連結されている。また、電源ユニット２の挿入方向先端には外部接続用の外部コネクタ８が設けられ、この外部コネクタ８を接続する固定側コネクタ９が前記負荷装置側に設けられている。尚、以下、電源ユニット２の挿入方向先端側を先端側、この挿入先端の他側を基端側という。
【００１６】
前記取付部材３には、前記放熱器４の長さ方向中間側が、前記ガイドレール７の長さ方向中間側にて回動可能に接続されており、この回動取付構造11は、前記放熱器４の長さ方向中央側に設けた回転中心軸12を、取付部材３の軸受部13に回動可能に接続してなり、その回動取付構造11は対をなして設けられている。前記放熱器４の内面と前記電源ユニット２の内面とが対向し、前記発熱部５は電源ユニット２の内面の基端側に設けられ、この発熱部５に対応して前記放熱器４の内面の基端側には受熱部４Ａが設けられている。前記放熱器４の先端側内面には、力点となる被当て部14が設けられ、この被当て部14に前記電源ユニット２の先端側内面の当て部15が当たり、電源ユニット２をガイドレール７，７にスライド挿入すると、作用点である基端側の受熱部４Ａが発熱部５に密着するように、被当て部14と当て部15などが設定されている。尚、この例では、前記外部コネクタ８の外面ケースが当て部15となっている。
【００１７】
前記電源ユニット２の基端側にはカバー部16が設けられ、基端側において、電源ユニット２の外面側と放熱器４の外面側を挟着するバネ性を有する固定手段たる挟着固定部材17により、受熱部４Ａと発熱部５とを密着状態で固定している。尚、前記放熱器４は、外面側に放熱用リブを有し冷却ファンで強制空冷するものや、外面川の放熱用リブで自然空冷するものや、パイプなどに冷却液を循環して水冷するものなど各種の物が用いられる。
【００１８】
次に前記電源装置の使用方法につき説明すると、電源ユニット２の取付の際には、図１に示すように、放熱器４を非受熱位置に回動しておき、ガイドレール７，７の間に電源ユニット２の先端側を挿入し、スライドさせると、電源ユニット２の当て部15が放熱器４の被当て部14に当たってこれを押し、基端側内面の受熱部４Ａが発熱部５に近づく方向に放熱器４が回動し、受熱部４Ａが発熱部５に密着する。そして、挟着固定部材17により、電源ユニット２と放熱器４とを挟むようにして両者を固定する。このように力点となる被当て部14に、電源ユニット２の先端側内面の当て部15が当たり、回転中心軸12を支点とした梃子の原理により、作用点である基端側において、発熱部４Ａに受熱部５が密着する。また、前記電源ユニット２のスライドにより、電源ユニット２の外部コネクタ８が固定側コネクタ９に挿入接続される。尚、挟着固定部材17以外の固定手段を用いることもできる。一方、寿命により電源ユニット２を交換する場合は、挟着固定部材17を外し、放熱器４の受熱部４Ａが発熱部５から離れる方向に該放熱器４を回す方向に力を加え、電源ユニット２を基端側に引くと、電源ユニット２を取付部材３から取り外すことができる。このようにして交換が必要となった電源ユニット２のみを交換し、放熱器４はそのまま使用することができる。そして、取付作業に用いる電源ユニット２は、従来のように放熱器一体型と異なるため、軽量となり、取付作業性の向上を図ることができる。このように、寿命部品である電源ユニット２の交換において、放熱器４を無駄なく継続使用でき、電源ユニット２も軽量となるから、その組み込み取り外しにおいて、作業を容易に行うことができる。また、この例では、放熱器４を負荷装置側の固定側取付部６に設けたから、電源ユニット２の重量体積を軽減でき、配送時、輸送重量体積の低減により配送費用の節減も可能となる。
【００１９】
このように本実施例では、請求項１に対応して、電源ユニット２を着脱可能に取り付ける取付部材３と、この取付部材３に設けられ電源ユニット２の発熱部５の熱を受ける放熱器４とを備えるから、電源ユニット２を取付部材３に取り付け、この取付部材３に設けた放熱器４により電源ユニット２の発熱部５の熱を放熱することができる。そして、電源ユニット２を交換する際は、取付部材３から電源ユニット２のみを取り外し、放熱器４はそのままで新しい電源ユニットを使用することができる。
【００２０】

【００２１】
また、このように本実施例では、請求項１に対応して、取付部材３に放熱器４が回動可能に設けられ、この放熱器４は発熱部５の熱を受ける受熱部４Ａを有し、この受熱部４Ａが発熱部５から熱を受ける受熱位置と非受熱位置に放熱器４が回動可能であるから、電源ユニット２を取付部材３に取り付け、放熱器４を受熱位置に回動してセットし、一方、電源ユニット２の交換時には、放熱器４を非受熱位置に回動して取付部材３から電源ユニット２を取り外すことができる。
【００２２】
さらに、このように本実施例では、請求項２に対応して、前記受熱位置で放熱器４を固定する固定手段たる挟着固定部材17を備えるから、挟着固定部材17により放熱器４を受熱位置で固定することができる。
【００２３】
また、このように本実施例では、請求項３に対応して、取付部材３は、電源ユニット２をスライド挿入するスライド挿入部たるガイドレール７，７を有するから、ガイドレール７，７間に電源ユニット２をスライド挿入して取付部材３に着脱することができる。
【００２４】
さらに、このように本実施例では、請求項４に対応して、ガイドレール７の中間側を回転中心として放熱器４を取付部材３に回動可能に設けており、取付部材３は、電源ユニット２をスライド挿入するスライド挿入部たるガイドレール７，７を有し、電源ユニット２はその先端側からガイドレール７，７にスライド挿入され、放熱器４には、回転中心である回転中心軸12より基端側に発熱部５に接する受熱部４Ａを設け、放熱器４の回転中心軸12より先端側には、電源ユニット２の先端側が当たって受熱部４Ａが発熱部５から熱を受ける受熱位置方向に回転する被当て部14を設けたから、受熱部４Ａが発熱部５に接する方向に該放熱器４を回転する被当て部14であり、電源ユニット２をスライド挿入すると、電源ユニット２の先端側の当て部15が放熱器４の被当て部14に当って、受熱部４Ａが発熱部５に接する方向に該放熱器４が回動し、発熱部５に受熱部４Ａを密着させて放熱器４をセットすることができる。
【００２５】
また、実施例上の効果として、取付部材３と固定側コネクタ９とを固定側取付部６に固設し、その固定側コネクタ９は外部コネクタ８の挿入位置に配置したから、取付部材３へのスライド挿入と同時に電源ユニット２の外部コネクタ８を固定側コネクタ９に接続することができる。
【００２６】
図５は本発明の第２実施例を示し、上記第１実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例では、放熱器４の基端側に回転中心軸12を設け、この回転中心軸12を回動可能に接続する軸受部13を取付部材３の基端側に設けている。また、前記発熱部５と受熱部４Ａとの間に放熱補助材31を設け、この放熱補助材31は、シリコンシートや、シート状にしたシリコンコンパウンドからなり、熱伝導率が高く、所定の弾性を有するものである。さらに、この例の固定手段はねじ32であり、放熱器４の基端側に設けた鍔孔33に前記ねじ32を挿通し、前記カバー部16のねじ孔34に前記ねじ32を螺着して固定している。
【００２７】
そして、図５に示すように、放熱器４が取付部材３から離れる方向に該放熱器４を回動し、取付部材３に電源ユニット２をスライド挿入して取り付け、放熱器４を逆方向に回動して、放熱補助材31を設けた発熱部５に受熱部４Ａを密着させ、ねじ32により固定することができ、このように電源ユニット２のみを交換して放熱器４を継続使用でき、請求項１〜５に対応して、上記第１実施例と同様な作用，効果を奏する。また、この例では、放熱補助材21によって放熱性を向上することができ、また、回転中心軸12を中心として放熱器４を回動した際、その弾性により発熱部５に受熱部４Ａを無理なく押し当てて密着させることができる。

[0016]
The radiator member 4 is connected to the attachment member 3 so that the intermediate side in the longitudinal direction of the radiator 4 can rotate on the intermediate side in the longitudinal direction of the guide rail 7. A rotation center shaft 12 provided at the center in the length direction 4 is rotatably connected to a bearing portion 13 of the attachment member 3, and the rotation attachment structures 11 are provided in pairs. The inner surface of the radiator 4 and the inner surface of the power supply unit 2 face each other, and the heat generating portion 5 is provided on the proximal end side of the inner surface of the power supply unit 2, and the inner surface of the radiator 4 corresponds to the heat generating portion 5. 4A of heat receiving parts are provided in the base end side. On the inner surface at the front end side of the radiator 4, there is provided a receiving portion 14 that becomes a power point. The abutting portion 15 on the inner surface at the front end side of the power supply unit 2 hits the receiving portion 14, and the power supply unit 2 is brought into contact with the guide rail 7. , 7, the receiving part 14 and the abutting part 15 are set so that the heat receiving part 4 </ b> A on the base end side, which is the action point, is in close contact with the heat generating part 5. In this example, the outer surface case of the external connector 8 is a contact portion 15.
[0017]
A cover 16 is provided on the base end side of the power supply unit 2, and on the base end side, a pinching fixing member as a fixing means having a spring property for pinching the outer surface side of the power supply unit 2 and the outer surface side of the radiator 4. 17, the heat receiving portion 4 </ b> A and the heat generating portion 5 are fixed in close contact.

Various things such as things are used.
[0018]
Next, a method of using the power supply device will be described. When the power supply unit 2 is attached, the radiator 4 is rotated to the non-heat receiving position as shown in FIG. When the distal end side of the power supply unit 2 is inserted and slid, the contact portion 15 of the power supply unit 2 hits the pressed portion 14 of the radiator 4 and pushes it, and the heat receiving portion 4A on the inner surface of the proximal end approaches the heat generating portion 5. The heat radiator 4 rotates in the direction, and the heat receiving portion 4 </ b> A comes into close contact with the heat generating portion 5. Then, the sandwiching fixing member 17 fixes both the power supply unit 2 and the radiator 4 so as to sandwich them.

Therefore, the power supply unit 2 is attached to the attachment member 3, and the heat of the heat generating portion 5 of the power supply unit 2 can be radiated by the radiator 4 provided on the attachment member 3. And when replacing | exchanging the power supply unit 2, only the power supply unit 2 can be removed from the attachment member 3, and the new power supply unit can be used with the heat radiator 4 as it is.
[0020]
