Further, it is provided with insulating lacquer layer between the flat copper coil and magnet ring.By insulating lacquer layer by flat copper coilFixed with the position of magnet ring.
Further, the flat copper coil is formed by one or more strands of flat type copper wire coilings.
Further, the operating temperature of the ring-like Flat wire vertical winding inductor of the high-cooling property is -20-80 DEG C.The scope of applicationExtensively, it disclosure satisfy that the use of most clients.
The beneficial effects of the utility model are：
A kind of ring-like Flat wire vertical winding inductor of high-cooling property described in the utility model, simple in construction, size is compact, can be withNeeded to adjust the number of turn of coiling according to energy storage size, and high current and performance stabilization, the anti-direct current of inductor can be bornAbility lifted 12% on the basis of original, it is not easy to saturation, and can be under conditions of 90A electric currents and -20 ~ 80 DEG C of environmentAt a temperature of normal work, with good market prospects.
