[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figures 1-4The utility model provides a heating coil box structure with end plate cooling, including box 1, cooling column subassembly, end plate cooling subassembly, cooling column subassembly sets up in the inside of box 1, and heating coil is around and is connected in cooling column subassembly, and end plate cooling subassembly is connected in the one side of box 1.

[0022] Specifically, the cooling column subassembly includes a hollow copper pipe 2, and the heating coil is wound around the hollow copper pipe 2; the hollow copper pipe 2 is connected with a cooling liquid.

[0023] Specifically, the end plate cooling subassembly includes a cooling plate 3, a first cooling channel 4 and a second cooling channel 5; the cooling plate 3 is connected to the box 1, the first cooling channel 4 is connected to the upper side wall of the cooling plate 3, and the second cooling channel 5 is connected to the lower side wall of the cooling plate 3. The first cooling channel 4 is in a U shape. The second cooling channel 5 includes an inner ring segment 51 and a square frame segment 52, the inner ring segment 51 is arranged inside the square frame segment 52, and the inner ring segment 51 and the square frame segment 52 are connected in communication.

[0024] Specifically, the heating coil is wrapped with a high-temperature-resistant insulation layer composed of a glass fiber heat insulation layer and a mica heat insulation plate. The high-temperature-resistant insulation layer made of glass fiber material has good insulation and high-temperature-resistant performance, further ensuring the safe and stable operation of the induction heating coil in a high-temperature environment.

[0025] Specifically, when the induction heating coil is working, on the one hand, the cooling liquid in the hollow copper pipe 2 cools the winding; on the other hand, the cooling liquid flows in the second cooling channel 5 to take away the heat of the end plate, thereby effectively cooling the end plate.
