Abstract
Description
壁を通したガス状態または液体状態の媒体の熱伝逹は次のように単純化できる。
Q=(Tガス−T冷却材)x(kxA)
この場合、
1/(kxA)=(1/αガスxAガス)+(S壁xA壁/λ壁)+(1/α液体xA液体)
ここで
A=表面積、
S=厚さ、
λ=熱伝導率
α=熱伝逹率
である。
一定の増加に対する代案として、本発明は好ましくはガス流入口からガス排出口までウェーブ形態のチャンネルのウェーブ振幅が不連続的に増加することによって改善される。ウェーブ振幅の不連続的増加は、複数の隣接したウェーブ振幅が同じ大きさを有し、同じ振幅を有するウェーブグループを形成することを意味し、この場合には、後続してさらに大きい振幅を有する次のウェーブグループが連結する。振幅の階段状のプロファイルはガスの流動経路に沿って形成される。
1.
冷却器のガス流入口側では、ガスと冷却剤との間の温度差が非常に大きく、ガスの熱伝逹率が非常に大きいため、ガスからの非常に大きい入熱(heat input)が発生する。高いガス温度によって、ガスはまた低い密度を有し、このような密度は大きい体積及びそれにより高い流動速度を引き起こす。
冷却器のガス排出口側では、その間、ガスが冷却され、ガスから冷却剤にただ小さな入熱だけが発生するが、その理由はガスと冷却剤との間の温度差が非常に小さく、ガスの熱伝達率が非常に小さいためである。低いガス温度によってガスは高い密度を有し、このような密度は小さな体積及びそれによる低い流動速度につながる。このようなことは貫流方向に熱伝逹が段々小さくなり、したがって冷却器の「後方」領域がガス排出前は非常に非効率的に用いられるという問題点を引き起こす。
リブ数によって調整されるガス側表面積の調整、及びガス流れの流動速度を変更するか、または壁近くで局部的な流動速度を変更することによる乱流の増加である。上記のような壁近くの局部的な流動速度/乱流はウェーブ振幅とウェーブ長さのリブ媒介変数により変更できる。ガス流れの流動速度はガスチャンネル断面積、高さ、幅またはガスチャンネルの数を通じても調整できる。このようなことは好ましくはU字形貫流またはS字形貫流冷却器で用いられる。I字形貫流冷却器に関しても原理は同様に適用できる。
小型部品は生産に必要な材料が少ないため、原材料コストが削減できる。
