Claims (11)
- 循環液の温度を調節する熱交換部を備えた熱交換器であって、
前記熱交換部において温度調節された前記循環液が流入する調温後液室が設けられていると共に、該調温後液室には該循環液中の空気を除去するフィルタが配されて、該調温後液室の壁部には脱気ポートが設けられており、該フィルタが該脱気ポートへ向けて傾斜して設けられていることを特徴とする熱交換器。 - 前記調温後液室は前記フィルタの両側が脱気前液室と脱気後液室とされており、前記脱気ポートが該脱気前液室の壁部に設けられている請求項1に記載の熱交換器。
- 前記フィルタが、前記調温後液室の壁部を構成するハウジングにインサート成形されたインサート構成部材とされている請求項1又は2に記載の熱交換器。
- 前記調温後液室内の温度を測定するための温度検出ポートが、前記調温後液室の壁部に設けられている請求項1〜3の何れか1項に記載の熱交換器。
- 前記脱気ポートの少なくとも根元部分が透明とされている請求項1〜4の何れか1項に記載の熱交換器。
- 前記フィルタが平坦な形状とされている請求項1〜5の何れか1項に記載の熱交換器。
- 前記フィルタが疎水性材料で形成されている請求項1〜6の何れか1項に記載の熱交換器。
- 前記フィルタが親水性材料で形成されている請求項1〜6の何れか1項に記載の熱交換器。
- 循環液の温度を調節する熱交換部を備えた熱交換器であって、
前記熱交換部において温度調節された前記循環液が流入する調温後液室が設けられていると共に、該調温後液室には該循環液中の空気を除去するフィルタが配されて、該調温後液室における該フィルタの両側が脱気前液室と脱気後液室とされていると共に、該フィルタが該調温後液室の壁部を構成するハウジングにインサート成形されたインサート構成部材とされていることを特徴とする熱交換器。 - 前記ハウジングが前記脱気前液室の壁部を構成する第1の液室壁部材と前記脱気後液室の壁部を構成する第2の液室壁部材とを備えており、前記フィルタが該ハウジングの該第1の液室壁部材に取り付けられている請求項9に記載の熱交換器。
- 前記熱交換部に連通されて前記循環液を該熱交換部へ導入する循環液入口ポートを備えた底部材が設けられており、
該底部材における該循環液入口ポートの開口と対向する部分には、該循環液入口ポートに向けて突出する分流突起が設けられていると共に、
該分流突起に対する該底部材の周方向の両側には、該底部材の周方向に延びるガイド突条が設けられている請求項1〜10の何れか1項に記載の熱交換器。
