その中心線のまわりに捩じつて螺旋状に形成し、
前記チユーブ１に内装されたインナーフインとを
具備するオイルクーラにおいて、設定温度以上の
とき前記螺旋状の捩じりのピツチが小さくなる形
状記憶合金で前記インナーフイン本体３を形成す
ると共に、該本体３の端部に圧縮付勢したコイル
バネ４の端部を位置させて、その伸縮により前記
本体３の前記ピツチ変化に伴う伸縮を吸収するよ
うに構成したことを特徴とするオイルクーラ。 A tube 1 through which oil flows, and a strip twisted around its center line to form a spiral shape,
In the oil cooler including an inner fin housed in the tube 1, the inner fin body 3 is formed of a shape memory alloy that reduces the pitch of the helical twist when the temperature is higher than a set temperature, and The oil cooler is characterized in that an end of a compressed coil spring 4 is positioned at the end of the body 3, and the expansion and contraction of the coil spring 4 absorbs the expansion and contraction of the main body 3 due to the pitch change.
