[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] See Figures 1 to 3 As shown, a multi-tube electromagnetic induction heating structure includes a blower 1, the outlet of which is connected to a multi-tube heating structure 2. In this embodiment, a sealing transition connector is provided at the connection between the outlet of the blower and the inlet of the multi-tube heating structure. This prevents air leakage and improves safety and reliability. The blower can deliver external air or external media into the multi-tube heating structure.

[0023] In this embodiment, the multi-tube heating structure includes a central tube 21, a middle tube 22 surrounding the central tube, and an edge tube 23 on the outer side of the middle tube. An electromagnetic induction coil 24 is wrapped around the outer side of the edge tube. The connection between the electromagnetic induction coil and the edge tube is fixed with thermally conductive adhesive. This ensures the stability of the electromagnetic induction coil connection, prevents displacement of the electromagnetic induction coil on the edge tube, and improves the stability and reliability of induction heating. In use, the electromagnetic induction coil is energized and generates an induced current, causing the central tube, middle tube, and edge tube to heat themselves and the air or grease inside the central tube, middle tube, and edge tube. Heating by electromagnetic means improves the heating uniformity of the overall structure. In this embodiment, the central tube, middle tube, and edge tube are all thermally conductive metal tubes. Specifically, the central tube, middle tube, and edge tube are all ferritic stainless steel tubes or austenitic stainless steel tubes.

[0024] Furthermore, in practical applications, the electromagnetic induction coil is wrapped with a sleeve 3. This sleeve is a conventional structure in existing technology, and is simply applied.

[0025] In this embodiment, the diameter of the central tube is larger than the diameter of the edge tube, and the diameter of the edge tube is larger than the diameter of the central tube.

[0026] Furthermore, a control switch 4 is installed on the blower. An electromagnetic induction circuit 5, connected to the electromagnetic induction coil, is installed on the outside of the sleeve. This facilitates control operation, and the electromagnetic induction circuit can also control the electromagnetic induction coil, improving the effectiveness and reliability of heating.

[0027] Its working principle is that the control switch starts the blower, which draws in external air into the multi-tube heating structure. After the electromagnetic induction coil is energized, it quickly generates an alternating magnetic field, which causes the central tube, middle tube and edge tube of the coil to heat up, rapidly heating the air inside the tube. Under the technical action of the blower, the heated air will be output through the multi-tube heating structure, ensuring that it is heated evenly and output.

[0028] In the heat transfer oil or grease heating process, turning on the switch starts the blower, which pushes the heat transfer oil or grease into the multi-tube heating structure. The electromagnetic induction coil works, generating an alternating magnetic field that induces current in the pipe to achieve heating. This rapidly heats the heat transfer oil or grease in the pipe, and the heated heat transfer oil or grease is output through the multi-tube heating structure, which can effectively control the temperature and ensure stable and efficient operation of the equipment.

[0029] This invention has the following positive effects: The structure of this invention is reasonably designed. It can draw external air into the multi-tube heating structure through a blower, and after the electromagnetic induction coil is turned on, it quickly generates an alternating magnetic field, causing the edge tubes, middle tubes and central tubes to heat up. This can quickly heat the air in the edge tubes, middle tubes and central tubes, and the heated air is output under the action of the blower. This helps to improve the temperature uniformity of the output air, resulting in good heating uniformity, stable and reliable use, and strong applicability.

[0030] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0031] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
