Description
これに関し、例えば、JP5941878B2号においては、排気ガスをハウジング内に収容された排気ガス管を通じて案内することが示されており、その結果としてハウジングと前記排気ガス管の間、または前記の排気管同志の間では、例えば、液体の状態での冷却剤、特に水(water)/グリコール(glycol)を含む流れが生じる。
図2によると、フランジ(22)と排気ガス管(12)との間にハウジング(26)が提供されており、この際、ハウジングは多数の排気ガス管(12)を囲んでおり、その結果として排気ガス管を通じて循環する排気ガスを冷却させるため側面密閉されている排気ガス管は液状冷却剤、例えば、水により循環できる。
固定位置(28)は図示した実施例の場合、流動方向に少なくとも数ミリ、例えば、5mm及び/又は最大2cmまで延長される。従って、次のようなことが分かる。前記のような実施例で、固定位置(28)が流れ方向に上流にある壁(20)の端部にそしてまた流入口に提供される場合、固定位置(28)の延長部により流動方向に、冷却剤を供給することが不可能である。従って、本発明による隙(16)により解決される上述した問題が発生し、この際、前記の隙は固定位置(28)を流動方向にある程度下方に移動させる。
前記実施例によると、排気ガス冷却器は互いに並んでいる2つの流入口と、このような流入口に連結されている「重なった(stacked)」排気ガス管のグループを備えるが、本発明による排気ガス冷却器は単一の流入口と、このような流入口に連結されている排気ガス管のグループ、そして2つ以上の流入口と、これに相応するように提供される排気ガス管を備える。
望ましい改善例は請求項に記述されている。
排気ガスの流動方向に前記の隙の寸法に関しては、最小の長さが5mmであり、そして/又は最大の延長部が2cmの場合、優秀な結果が期待できる。
このような結果は、流動の方向に垂直に寸法が最小1mm及び/又は最大5mmである場合にも同様に適用される。
本発明による長所は特に、1つ以上の排気ガス管を備える排気ガス冷却器において用いることができ、この際、前記の排気ガス管は.3mm乃至0.5mmの厚さを有する1つ以上の壁を持つ。前記のような管は比較的厚さが少なく、従って「軽量に」形成され、本発明による措置で同時に流入口での損傷を防止できる。
本発明による排気ガスの冷却器が排気ガスの再循環の冷却器として用いられる場合、前記本発明による排気ガスの冷却器は特殊な長所を示す。
従って、本出願書は前記のような1つ以上の冷却器を備える排気ガスの再循環システムも対象にする。
