Inductance coil

The utility model provides an inductance coil which is formed by winding a single copper pipe and comprises a first straight line section, a bent section and a second straight line section which are sequentially arranged, a first pin is welded on the first straight line section, and a second pin is welded on the second straight line section. And an insulating layer is arranged on the outer pipe wall of the copper pipe. According to the inductance coil provided by the utility model, the coil is formed by winding the copper pipe, and the water-cooling pipe joints are arranged at the two ends of the copper pipe so as to be connected into an external cooling water circulation system, so that the rapid heat removal of the coil can be realized, and the coil is not easy to overheat or burn down when working; the coil can be ensured to run lastingly and stably, the service life of the coil is greatly prolonged, and the use requirement of a user is met. 本实用新型提供一种电感线圈，所述电感线圈由单根铜管绕制而成并包括依次设置的第一直线段、弯曲段和第二直线段，所述第一直线段上焊接有第
