For a better understanding of the present invention, be described further below in conjunction with the drawings and specific embodiments.
The principle of electromagnetic heater is to utilize electromagnetic controller that AC rectification is become direct current, again direct current is converted to frequency and is the high-frequency high-voltage more than the 20KHz, the high-frequency high-voltage current that changes the at a high speed solenoid of flowing through can produce the nuclear varying magnetic field that changes at a high speed, when the inboard magnetic line of force in magnetic field causes the iron atom high-speed motion during by iron plate, the mutual friction of iron atom phase makes voluntarily at a high speed heating of iron plate itself, utilizes the iron plate of heating that object is heated.General electromagnetic heater only directly heats solid, can not be used for the heating of convection cell; Namely be used in fluid heating, because the fluid Negotiation speed is fast, contact area and time of contact are limited, also can't reach higher temperature after the heating.
In order to overcome the problems referred to above, the present invention adopts the heat conduction fin to link to each other with iron plate; Therefore, heat conduction fin and iron plate have uniform temp.And the heat conduction fin is provided with bent sheet, can increase the collision frequency of fluid and heat conduction fin, increases the time of heat exchange, improves the temperature of output fluid.
As shown in Figure 1, electromagnetic heater of the present invention comprises positive and negative electrode, electromagnetic controller, solenoid 1, partiting thermal insulation bed course 2, iron square tube 3, heat conduction fin 4; Described heat conduction fin 4 is embedded in the described iron square tube 3, and described partiting thermal insulation bed course 2 is wrapped in outside the described iron square tube 3, and described solenoid 1 is wrapped in outside the described partiting thermal insulation bed course 2.
As shown in Figure 2, described iron square tube 3 is comprised of 4 rectangle iron plates, and the first iron plate 31 is relative and identical with the second iron plate 32, is wide rectangle iron plate; The 3rd iron plate 33 is relative and identical with the 4th iron plate 34, is narrow rectangle iron plate.Described the first iron plate 31 has many row's hole clippings 35, and every row has a plurality of hole clippings 35.In like manner, also have many row's hole clippings 35 on second iron plate 32 identical with the first iron plate 31.
As shown in Figure 3, described heat conduction fin 4 is the elongated copper sheet that is complementary with described iron square tube 3.The limit that described heat conduction fin 4 and iron plate are chimeric is rabbet 41, and described rabbet 41 is comprised of protuberance 411 and depressed part 412.Described heat conduction fin 4 is provided with many row's bent sheet 42.
As shown in Figure 3, described heat conduction fin 4 is the large heat conduction fin 4A among Fig. 1, and its two long limits are rabbet 41.Article one, in the hole clipping 35 that the protuberance on the rabbet 41 411 embeds on the first iron plate, in the hole clipping 35 that the protuberance 411 on another rabbet 41 embeds on the second iron plate, described depressed part 412 contacts with the iron plate inwall of 35 of adjacent hole clippings.Each large heat conduction fin 4A has 2 row's bent sheet 42 at least, and described bent sheet 42 is to the same side bending of large heat conduction fin 4A.The side that bent sheet 42 bends towards is the front of large heat conduction fin 4A, and another side is the back side of large heat conduction fin 4A.The identical faces of adjacent 2 large heat conduction fin 4A is oppositely arranged, and namely the back side is relative with the back side, or front and vis-a-vis.
Because heat conduction fin 4 is copper sheet, certain hardness is arranged, caused certain difficulty to assembling.For ease of assembly, as shown in Figure 4, described large heat conduction fin 4A can be comprised of 2 half fins.It is rabbet 41 that each half fin only has a long limit, and another long limit is straight flange.In the hole clipping 35 that protuberance 411 on the rabbet 41 of the first half fin 4a is embedded on the first iron plate, protuberance 411 on the rabbet 41 of the second half fin 4b is embedded in the hole clipping 35 of the upper relevant position of the second iron plate, after iron square tube assembling was finished, the straight flange of above-mentioned two and half fins just in time contacted.Preferably, have at least row's hole clipping 35 on each half fin.
For the structure of more detailed description bent sheet, now describe as an example of half fin example.As shown in Figure 5, described bent sheet 42 is to separate with heat conduction fin 4 on three limits that heat conduction fin 4 is stamped to form, with heat conduction fin 4 link to each other on one side, to the little rectangular sheet of certain orientation bending.As shown in Figure 6, the opening that forms because of the preparation bent sheet on the heat conduction fin is bending opening 43.The side that bent sheet 42 bends towards is the front of half fin 4a, and another side is the back side of half fin 4a.
When on only having the first iron plate 31 and the second iron plate 32, heat conduction fin 4 being housed, only have the heat energy of the first iron plate 31 and the second iron plate 32 effectively to derive, the 3rd iron plate 33 of iron square tube and the heat energy on the 4th iron plate 34 can not effectively be derived, and have caused the waste of heat energy.
When 4 iron plates of iron square tube 3 all were equipped with the heat conduction fin, the efficient of heat exchange was higher.For this reason, preferably on the 3rd iron plate 33 and the 4th iron plate 34, also have many row's hole clippings 35, and link to each other with heat conduction fin 4 by described hole clipping 35, as shown in Figure 2.With the 3rd iron plate 33, heat conduction fin 4 that the 4th iron plate 34 is chimeric be little heat conduction fin.Little heat conduction fin 4B comprises two sidewalls and a connecting portion, and sidewall is similar to half fin, and two sidewalls link to each other by connecting portion, and integral body is " U " type; Described sidewall and described the 3rd iron plate 33 or the 4th iron plate 34 chimeric limits are rabbet, and its protuberance is embedded in the hole clipping 35 of the 3rd iron plate 33 or the 4th iron plate 34, are provided with at least row's bent sheet 42 on each sidewall.Bent sheet 42 outwards on the same little heat conduction fin 4B, symmetrical along the center line mirror image of connecting portion.
