technical field [0001] The invention belongs to the field of device cooling methods, and in particular relates to a cooling method for improving a double-turn inductor. Background technique [0002] High-frequency heating is inseparable from high-frequency heating inductors. Double-turn inductors are the most used inductors in the quenching process of workpieces. Common high-frequency heating machine inductors are mostly wound with copper tubes. Bending in multiple places, using the electromagnetic induction formed by the copper tube to generate eddy current in the workpiece to heat the workpiece.

AI Technical Summary

Problems solved by technology

When the high-frequency heating sensor is in the heating process, the copper tube itself is also consuming electric energy, and the copper tube will generate heat during this process. The temperature of the sensor itself rises during operation, which will cause the resistance of the sensor to rise and increase energy consumption. Reduce the effective power of the equipment to heat the workpiece; if the cooling is not good and the temperature rises further, it will cause the sensor to melt and the heating process will fail

[0003] When the inductor is heated, enough cooling water needs to pass through the inner wall of the copper tube, and the cooling water can cool the copper tube, such as figure 1 As shown, the traditional copper pipe 1 is wound from a complete steel pipe. The diameter of the copper pipe 1 is 8mm and the wall thickness is 1mm. The cooling water can only enter from the left end of the copper pipe 1, and then from the The output at the other end on the left, the temperature of the cooling water at the water outlet 3 of the copper pipe 1 increases, which will cause the temperature of the cooling water at the water inlet 2 to be affected by the water outlet 3 to rise, resulting in the cooling of the entire copper pipe 1 At the same time, the copper pipe 1 at the bend will reduce the flow rate of cooling water, thereby reducing the flow rate of cooling water per unit time and reducing the cooling effect

At the same time, some products limit the size of the sensor when heating, such as high-frequency heating of small holes, the size of the hole determines the size of the sensor, we cannot cool the sensor by increasing the size of the sensor copper tube 1

Due to the large diameter of the copper tube 1 and the large diameter of the copper tube 1, only high-frequency heating can be performed on workpieces with a large heating surface. When high-frequency heating is required for small holes, the diameter and volume of the copper tube 1 , it is difficult to use a copper tube 1 with a diameter of 8 mm and a wall thickness of 1 mm for high-frequency heating
