[0027] The following is combined with Figure 1-2 This application is described in further detail.
[0028] Example 1
[0029] The present application requests the disclosure of an electromagnetic induction heating perturbation wave temperature equalization device, which is used to interfere with the trajectory of electromagnetic waves and disperse the heat collection intensity of electromagnetic waves at the electromagnetic intersection, thereby changing or reducing its heat collection characteristics, and then achieving temperature equalization. The device also has the function of auxiliary heating, and the device is made of electromagnetic induction material. When the device is irradiated by electromagnetic wave eddy current, heat is generated to complete the auxiliary heating operation.
[0030] The device of the present application includes: a device body 1, the material of the device body 1 is an electromagnetic induction material, which can be silicon steel, nebium iron boron material, ferrite material, low carbon steel, nickel iron alloy, iron chromium cobalt alloy, aluminum nickel cobalt alloy, etc. The cross section of the device body 1 can be various, common rectangular, triangle, pentagon and other polyhedrons, circle, ring, or other special shapes, such as graphics including curved edges. The function of the device body 1 is to disrupt or disperse the electromagnetic waves at the intersection of electromagnetic waves. Placing the device body 1 between the electromagnetic induction coil and the heated body can make the heated body heated evenly.
[0031] Furthermore, the shape of the device body 1 can be a rectangular parallelepiped, which is convenient for installation and coordination with electromagnetic heating equipment on the market, and the shape is relatively regular.
[0032] Furthermore, in order to enhance the wave disturbance effect of the device, a plurality of depressions 2 are arranged in an array on the side wall of the device body 1 of the embodiment of the present application to increase the roughness and undulation of the surface of the device body 1, thereby more fully disrupting the electromagnetic waves. At the same time, the specific surface area of the device body 1 can also be increased, thereby increasing its auxiliary heating effect.
[0033] Furthermore, the shape of the recess 2 is spherical, and the extent of the recess 2 does not exceed half of a sphere, which facilitates the release of heat generated by the electromagnetic waves in the device body 1 and uniformly heats the heated object.
[0034] In order to further enhance the auxiliary heating function of the device body 1, the present application has heat release holes 3 extending through the centers of two spherical depressions 2 that are separated from each other, thereby further increasing the heat transfer path and enhancing the auxiliary heating efficiency of the device. This design is also beneficial for weight reduction, while increasing the installation compatibility of the device of the present application with existing electromagnetic heating devices on the market.
[0035] Example 2
[0036] The shape of the device body 1 of the present application is different from that of Example 1. The difference lies in that the cross-section of the device body 1 of the present application includes two opposite curved sides and two opposite straight sides, and the curved side is a curve formed by n S-shaped shapes connected in sequence; n is a natural number not less than 1, that is, the side wall of the device body 1 becomes uneven, further increasing the effect of the device in dispersing electromagnetic waves. At the same time, the design of the curved side will also have a larger heating area than the flat side, which can ensure that the heated object is heated evenly.
[0037] Example 3
[0038] The present application discloses an electromagnetic induction heating disturbance wave temperature equalization device, wherein the cross section 5 of the temperature equalization disturbance wave device body is honeycomb-shaped, such as Figure 3 As shown, the device is applied to a heating pipe.
[0039] In the field of heating pipes, pipes transport heat media and exchange heat to the external environment through the pipe wall. Electromagnetic induction heating in heating pipes uses the principle of electromagnetic induction to generate heat inside the pipe, and does not produce smoke, exhaust gas and other environmentally harmful substances in the process. There is no open flame involved in the heating process, which is highly safe. However, electromagnetic heating in heating pipes also involves the problem of uneven heating of the heat medium due to the intersection of electromagnetic waves. Therefore, Figure 3 As shown, the honeycomb-shaped temperature-averaging disturbance device body is built between the pipe walls 4, so that the heated water, air and other liquid and gaseous flowing heat media in the pipe are evenly heated. At the same time, its auxiliary heating function and the increase of the heat dissipation area are more conducive to improving the heating efficiency.
[0040] Example 4
[0041] The present application discloses an electromagnetic induction heating disturbance wave temperature equalization device, which is different from the embodiment 3 in that: Figure 4 As shown, the cross-section 5 of the body of the uniform temperature disturbance device provided in the embodiment of the present application is also honeycomb-shaped, but is provided with a plurality of plum blossom-shaped holes in an annular array for the flow of the flowing heat medium, thereby facilitating multi-angle disturbance and achieving uniform temperature heating.
[0042] In summary, the present application can be used in the following commercially available electromagnetic heating devices:
[0043] 1. After the electromagnetic induction heating perturbation wave temperature equalization device of the present application is installed in a household induction cooker, temperature equalization operations can be completed, such as making pancakes and crepes. The device can be placed at the bottom of the pot, or between the electromagnetic heating coil and the bottom of the pot, to interfere with the intersection of electromagnetic waves, so that the heating of the induction cooker is in a uniform temperature state.
[0044] 2. After the electromagnetic induction heating perturbation wave temperature equalization device of the present application is installed in the pancake oven, pancake box, and pancake drum, temperature equalization operation can also be achieved, effectively avoiding the excessive temperature difference between the middle heat collection area and the non-heat collection areas on both sides, thereby failing to meet the technical problem of uniform temperature heating.
[0045] 3. During pipeline heating, a disturbance wave device can also be installed. In the field of electromagnetic heating, the application of pipeline heating is very common. The electromagnetic induction heating disturbance wave temperature equalization device of this application is installed inside the pipeline to interfere with the electromagnetic waves, thereby achieving temperature equalization.
[0046] Fourth, the electromagnetic heating roller may also be equipped with the disturbance wave device of the present application. The electromagnetic induction heating disturbance wave temperature equalization device of the present application may be installed outside the electromagnetic heating coil of the electromagnetic heating roller and between the heated roller wall to achieve a uniform temperature effect.
[0047] 5. For inner arc-shaped and outer arc-shaped heating tiles, the electromagnetic induction heating disturbance wave temperature equalization device of the present application is installed between the heating coil and the heated induction material to achieve a uniform temperature effect.
[0048] In short, the electromagnetic induction heating disturbance wave temperature equalization device is a device made of electromagnetic induction material and added between the electromagnetic induction coil and the heated body. It is used to disperse and reduce the heat collection of the electromagnetic waves of the heated body, and one or more layers can be set according to the strength and power of the electromagnetic induction frequency, and has good practicality.
[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and improved concepts of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
