The metal is placed in this space to be heated, and the cooling of the coil is often Cooling water pipes are arranged on the inner and outer surfaces of the coil to reduce the temperature of the inner and outer sides of the coil through water flow, but limited to the shape of the coil and the cooling water pipe, the contact area between the two is small, and the cooling effect is not good.

Utility model content

In order to solve the problem of poor heat dissipation of the induction heating coil used in the induction heating equipment in the prior art, the utility model provides a segmented induction heating coil used in the medium frequency induction heating equipment.

The technical scheme adopted by the utility model to solve the above technical problems is: a segmented induction heating ring for intermediate frequency induction heating equipment, the induction heating ring is formed by arranging multiple groups of induction coils in sequence, and one side of the induction coil is provided with The water inlet pipe and the water discharge pipe, the induction coil is made of copper coils with wires passing through the water, and its two ends are respectively provided with a water inlet and a water outlet, and the water inlet and the water outlet are respectively connected with the water inlet pipe and the water discharge pipe.

In the utility model, the number of groups of induction coils can be arranged according to needs. The water inlets on each group of induction coils are connected with the water inlet pipes, and the water outlets are connected with the drain pipes. By injecting cooling water into the water inlet pipes, cooling The water is diverted to each group of induction coils through the water inlet, where it flows to take away heat, and then is discharged through the water outlet and drain pipe to form a water cooling cycle.

Beneficial effects: the utility model makes the induction heating coil a segmented structure, and each segment is made of a copper ring with a wire passing through water, and cooling water is passed into each segment to form a water cooling cycle, which greatly improves the cooling efficiency.
