Abstract
Description
このような電子機器は、「電子素子を含む実装部品」を実装された回路基板を、筐体により保持した構造のものが多い。
回路基板に実装される実装部品には、例えば、演算処理チップ等「使用により発熱」する発熱性の電子素子が含まれる。
発熱性の電子素子は動作時に発熱するので、発生する熱を適切に処理しないと、素子自体が高温となって、素子自体の機能を妨げたり、素子周辺の実装部品の機能に影響したりする。
図1は、撮像装置1の外観を示す図である。
符号2Aで示す部分は「撮像部に含まれるレンズの1つ」である。
図3は、筐体3から筐体部分3Aを取り外した状態を示している。筐体部分3Bには、レンズ2A等を含む撮像部と回路基板4が組み込まれ、ねじで固定されている。
従って、演算処理チップ5A等で発生する熱の処理が必要となる。
「クリーム状の導熱媒質」は、液体のような流動性はないが、機械的な外力が作用すると、外力に從って自在に変形する。イメージとしては「化粧品のクリーム」に近い。
この撮像装置は、全天球型の撮像装置であり、図1において、レンズ2Aを示した「撮像部」は、図6や図7に示すように、レンズ2Aとともにレンズ2Bを有し、これらレンズ2A、2Bは、2系統の光学系にそれぞれ含まれている。
熱拡散体6は、上記の如く、発熱により温度上昇する部分に直接もしくは熱伝導体を介して面接触し、温度上昇する部分からの熱を有効に吸収し、熱拡散体全体に拡散する。
発熱性の電子素子5A等を含む実装部品を実装された回路基板4、11と、該回路基板4、11を内部に保持する筐体3と、該筐体内に前記回路基板とともに保持される熱拡散体6とを有し、前記熱拡散体6は、液状もしくはクリーム状の導熱媒質9を変形自在なパック容器8内に密封してなり、前記回路基板の前記発熱性の電子素子5A等およびその周辺領域の3次元形状に倣って変形する構成である電子機器1。
[1]記載の電子機器であって、熱拡散体6が、少なくとも発熱性の電子素子5A等に直接接触する電子機器。
[1]記載の電子機器であって、熱拡散体6が、少なくとも発熱性の電子素子5A等に、シート状の熱伝導体7を介して接触する電子機器。
液状もしくはクリーム状の導熱媒質9を変形自在なパック容器8内に密封してなり、発熱性の物品およびその周辺領域の3次元形状に倣って変形する構成である熱拡散体6。
[4]記載の熱拡散体であって、パック容器8内に密封された導熱媒質9が液状である熱拡散体。
[4]記載の熱拡散体であって、パック容器8内に密封された導熱媒質9がクリーム状である熱拡散体。
[6]記載の熱拡散体であって、クリーム状の導熱媒体が、複数種の材料により構成され、時間経過とともに固形化する熱拡散体。
[4]ないし[7]の何れか1に記載の熱拡散体であって、[1]ないし[3]の何れか1に記載の電子機器に使用される熱拡散体。
レンズ2A、2Bを含む撮像部を有し、撮像装置1として構成される[1]〜[3]の何れか1に記載の電子機器。
3A、3B 筐体部分(筐体を構成する。)
4、11 回路基板
5A、5B、5C 演算処理チップ(発熱性の電子素子)
6 熱拡散体
8 パック容器
9 導熱媒質
