Abstract
【解決手段】冷却ユニット40は、部品ユニット27と、クーリングプレート41とを有する。部品ユニット27は、電子部品31と、電子部品31の側部及び上部を覆うポッティング材33とを含み、上部が錘状に形成されている。また、クーリングプレート41は、部品ユニット27の上部が嵌合する錘状の穴41aと、冷媒が通流する流路42とを備えている。
【選択図】図6
Description
図3は第1の実施形態に係る情報処理装置の一例を示すブロック図、図4は情報処理装置が収納されたラックを示す斜視図(模式図)である。本実施形態では、情報処理装置がデータセンター用のサーバの場合について説明している。
第1の実施形態では、トランス31に被せる部品ケース32の上部を円錐台形状にしている。そのため、図9に示すように、クーリングプレート41は、部品ケース32の中心を軸として回転可能であり、回転方向に位置ずれが起こることが考えられる。
図12(a)は第2の実施形態の変形例1の冷却ユニット60で用いるトランスユニット61の側面図、図12(b)は同じくそのトランスユニット61の上面図である。また、図13は、変形例1に係る冷却ユニット60を示す上面図である。
図14(a)は第2の実施形態の変形例2の冷却ユニット70で用いるトランスユニット71の側面図、図14(b)は同じくそのトランスユニット71の上面図である。また、図15は、変形例2に係る冷却ユニット70を示す上面図である。
図16は、第3の実施形態に係る冷却ユニットを示す模式図(断面図)である。
図18は、第4の実施形態に係る冷却ユニットを示す模式断面図である。本実施形態が第1の実施形態と異なる点は部品ケースがないことにあり、その他の構成は基本的に第1の実施形態と同様である。そのため、図18において、図6と同一物には同一符号を付して、その詳細な説明は省略する。
第1の実施形態(図6参照)では部品ケース32内にトランス31及びポッティング材33を配置してトランスユニット27とし、トランスユニット27の部品ケース32をクーリングプレート41の穴に嵌合させて冷却ユニット40としている。
