Cooling body

冷却体

Abstract

<P>PROBLEM TO BE SOLVED: To provide a cooling body, in which a liquid coolant flows once through the interior, heightening the cooling capability without any increase in flow of the liquid coolant. <P>SOLUTION: In the cooling body coming into contact with a heating unit and provided with a once-through passage disposed in the interior for the liquid coolant to flow once through a zigzag once-through passage allowing the liquid coolant to flow from one end to the other end while the flow direction is changed to the direction vertical to the contact surface and to the parallel direction so as to come into contact with both surfaces alternately is provided between both opposite surfaces which are contact surfaces between the cooling body and the heating unit. <P>COPYRIGHT: (C)2005,JPO&NCIPI
【課題】内部に冷却液を貫流させる形式の冷却体において、冷却液の流量を増加させることなく冷却能力を高めることのできる冷却体を提供することを目的とする。 【解決手段】発熱体に接触され、内部に冷却液の貫流する貫流路を設けた冷却体において、この冷却体の発熱体との接触面となる対向する両面の間に、冷却液がその一方端からこの両面の各面に交互に接触するように流れの方向を接触面に垂直な方向と平行な方向に変更しながら他方端へ貫流するジグザグ状の貫流路を設ける。 【選択図】 図3
