Description
好ましくは、前記積層ユニットには、前記巻付部材の長手方向に沿って延び、前記巻付部材を収容可能な収容溝が形成されている。以上の構成によれば、前記巻付部材の長手方向に対して直交する方向における前記巻付部材の移動を抑制することができる。
好ましくは、前記巻付部材は、前記複数の冷却器に対して溶接されている。以上の構成によれば、前記複数の冷却器間の相対的な位置関係が安定する。
好ましくは、前記巻付部材は金属製の帯であり、前記帯には、前記複数の冷却器と対向する位置に複数の溶接孔が形成されており、前記複数の溶接孔の周縁において、前記帯は前記複数の冷却器に対して溶接されている。以上の構成によれば、前記巻付部材を前記複数の冷却器に対して効率よく固定することができる。
本願発明の第2の観点によれば、複数の半導体モジュールと、冷媒の流路を有する複数の冷却器と、を交互に積層して積層ユニットを形成し、積層方向で隣り合う2つの前記冷却器の間に、前記積層方向で隣り合う2つの前記冷却器の前記流路同士を連結するシール部材を配置した状態で、前記積層ユニットを前記積層方向で加圧し、前記積層ユニットを加圧した状態で前記積層ユニットに巻付部材を巻き付けることで、前記積層ユニットの前記積層方向に加圧された状態を維持する、半導体装置の製造方法が提供される。以上の方法によれば、前記積層ユニットの前記積層方向に加圧された状態を維持する機能を損なうことなく、上記特許文献1のスタッドボルトを省略できるので、前記半導体装置を小型化することができる。
以下、図1〜図6を参照して、半導体スタック1を説明する。半導体スタック1は、インバータやコンバータなどの電力変換装置として機能する半導体装置である。
次に、図7及び図8を参照して、第2実施形態を説明する。以下、本実施形態が上記第1実施形態と異なる点を中心に説明し、重複する説明は適宜省略する。
次に、図9及び図10を参照して、第3実施形態を説明する。以下、本実施形態が上記第2実施形態と異なる点を中心に説明し、重複する説明は適宜省略する。
