Claims (1)
間に熱交換を行なわせるヘリカルコイル伝熱管において
、上記ヘリカルコイル伝熱管で構成される円筒状管壁の
内径層を通る管外流体の流れ方向に対して最適伝熱条件
となる角度で上記伝熱管外周に環状溝を所定ピッチで刻
設したことを特徴とするヘリカルコイル伝熱管。In a helical coil heat exchanger tube that performs heat exchange between an internal fluid flowing inside the tube and an extratubular fluid flowing outside the tube, the outside of the tube passes through the inner diameter layer of the cylindrical tube wall constituted by the helical coil heat exchanger tube. A helical coil heat exchanger tube, characterized in that annular grooves are carved at a predetermined pitch on the outer periphery of the heat exchanger tube at an angle that provides optimum heat transfer conditions with respect to the flow direction of the fluid.
