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 utilizes electromagnetic controller that AC rectification is become direct current, direct current is converted to the high-frequency high-voltage that frequency is more than 20KHz again, the high-frequency high-voltage current of change flows through the core varying magnetic field that solenoid can produce change at a high speed at a high speed, inside magnetic field, the magnetic line of force is by causing iron atom high-speed motion during iron plate, the mutual friction of iron atom phase makes iron plate heating at a high speed voluntarily itself, utilizes the iron plate of heating to heat object.General electromagnetic heater only directly heats solid, can not be used for the heating to fluid; Namely be used in fluid heating, because fluid Negotiation speed is fast, contact area and time of contact limited, also cannot reach higher temperature after heating.
In order to overcome the problems referred to above, the present invention adopts heat conduction fin to be connected with iron plate; Therefore, heat conduction fin and iron plate have identical temperature.And heat conduction fin is provided with bent sheet, the collision frequency of fluid and heat conduction fin can be increased, increase the time of heat exchange, improve 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 to be embedded in described iron square tube 3, and described partiting thermal insulation bed course 2 is wrapped in outside described iron square tube 3, and described solenoid 1 is wrapped in outside described partiting thermal insulation bed course 2.
As shown in Figure 2, described iron square tube 3 is made up of 4 pieces of rectangle iron plates, and the first iron plate 31 is relative and identical with the second iron plate 32, is wide rectangle iron plate; 3rd iron plate 33 is relative and identical with the 4th iron plate 34, is narrow rectangle iron plate.Described first iron plate 31 has many row's hole clippings 35, and often row has multiple hole clipping 35.In like manner, the second identical with the first iron plate 31 iron plate 32 also has and arranges hole clipping 35 more.
As shown in Figure 3, described heat conduction fin 4 is the elongated copper sheet matched with described iron square tube 3.Described heat conduction fin 4 limit chimeric with iron plate is rabbet 41, and described rabbet 41 is made up 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 in Fig. 1, and its two long limits are rabbet 41.Article one, the protuberance 411 on rabbet 41 embeds in the hole clipping 35 on the first iron plate, and the protuberance 411 on another rabbet 41 embeds in the hole clipping 35 on the second iron plate, and the iron plate inwall between described depressed part 412 with adjacent hole clipping 35 contacts.Each large heat conduction fin 4A has 2 row's bent sheet 42 at least, and described bent sheet 42 bends to the same side 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, there is certain hardness, cause certain difficulty to assembling.Conveniently assemble, as shown in Figure 4, described large heat conduction fin 4A can be made up of 2 half fins.Each half fin only has a long limit to be rabbet 41, and another long limit is straight flange.Protuberance 411 on the rabbet 41 of the first half fin 4a is embedded in the hole clipping 35 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 has been assembled, the straight flange of above-mentioned two and half fins has just in time contacted.Preferably, each half fin at least has row's hole clipping 35.
In order to describe in more detail the structure of bent sheet, be now described for half fin.As shown in Figure 5, described bent sheet 42 is that three limits be stamped to form on heat conduction fin 4 are separated with heat conduction fin 4, is connected with heat conduction fin 4, to the little rectangular sheet of certain orientation bending.As shown in Figure 6, opening heat conduction fin formed because of preparation bent sheet 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 only have the first iron plate 31 and the second iron plate 32 are equipped with heat conduction fin 4 time, the heat energy of the first iron plate 31 and the second iron plate 32 is only had effectively to derive, heat energy on 3rd iron plate 33 of iron square tube and the 4th iron plate 34 can not effectively be derived, and causes the waste of heat energy.
When 4 iron plates of iron square tube 3 are all equipped with heat conduction fin, the efficiency of heat exchange is higher.For this reason, preferably also have on the 3rd iron plate 33 and the 4th iron plate 34 and arrange hole clipping 35 more, and be connected with heat conduction fin 4 by described hole clipping 35, as shown in Figure 2.Be little heat conduction fin with the 3rd iron plate 33, heat conduction fin 4 that the 4th iron plate 34 is chimeric.Little heat conduction fin 4B comprises two sidewalls and a connecting portion, and sidewall is similar to half fin, and two sidewalls are connected by connecting portion, overall in " U " type; The described sidewall limit chimeric with described 3rd iron plate 33 or the 4th iron plate 34 is rabbet, and its protuberance is embedded in the hole clipping 35 of the 3rd iron plate 33 or the 4th iron plate 34, each sidewall is at least provided with row's bent sheet 42.Bent sheet 42 on same little heat conduction fin 4B outwards bends, along the center line specular of connecting portion.
Electromagnetic heater of the present invention is prepared by the following method, and 1) iron plate is cut into wide rectangle and narrow rectangle, vacate hole clipping 35 at the appropriate location basket of wide rectangle or wide rectangle and narrow rectangle; 2) copper sheet is made heat conduction fin 4, copper sheet stamps out bent sheet 42, and rabbet 41 is made on long limit; 3) sequentially injected by the protuberance 411 of heat conduction fin 4 after in the hole clipping 35 of iron plate, joint filling full weld, can not leak out; 4) two pieces of chimeric heat conduction fin 4 wide rectangle iron plates and narrow rectangle iron plate are welded into iron square tube 3, described narrow rectangle iron plate can be fitted together to heat conduction fin 4; 5) at iron square tube 3 outer wrapping partiting thermal insulation bed course 2; 6) described electromagnetic heater is namely made at the outer solenoid 1 that is wound around of partiting thermal insulation bed course 2.
Because electromagnetic heater of the present invention have employed the mode of high-frequency electromagnetic coil eddy-current heating, compared with use coal or combustion gas, more save the energy; And the heat produced is owing to being subject to the isolation of partiting thermal insulation bed course, cannot be lost to surrounding space, heat is all derived fast to iron square tube outlet, improves heat utilization rate.
Another object of the present invention is to provide a kind of electromagnetism heating equipment.As shown in Figure 7, described electromagnetism heating equipment is generated by fluid or storage facilities, fluid enters pipe 5, fluid goes out pipe 6 and above-mentioned electromagnetic heater forms, the two ends of the iron square tube 3 of described electromagnetic heater enter pipe 5 respectively and go out pipe 6 with fluid and be connected with fluid, the other end that fluid enters pipe 5 generates with fluid or storage facilities is connected.Now, iron square tube 3 entirety is a fluid passage 38.Described fluid generates or storage facilities is used for providing fluid, and conventional fluid generates or storage facilities has blower fan, storage tank etc., provides the fluid such as gas and liquid respectively.
Preferably, as shown in Figure 7, be provided with iron dividing plate 36 in the iron square tube 3 of described electromagnetic heater, iron square tube 3 is divided into multiple Electromagnetic Heating unit 37, each Electromagnetic Heating unit is a fluid passage 38; Entering with fluid the Electromagnetic Heating unit end that pipe 5 is connected is fluid intake end, and going out with fluid the Electromagnetic Heating unit end that pipe 6 is connected is fluid outlet, and other ends of Electromagnetic Heating unit 37 are revolution end; Described electromagnetism heating equipment also comprises return bend 7, and return bend 7 is for connecting the same end revolution end of adjacent Electromagnetic Heating unit 37.
As shown in Figure 8, in fluid passage 38, adjacent 2 large heat conduction fin 4A identical faces are relative, even the back side is relative with the back side, or front and vis-a-vis.The overbending direction of the bent sheet in each fluid passage 38 is identical with fluid flow direction.Fluid enters pipe 5 from fluid and enters fluid passage 38, and fluid passes through from the interval of adjacent heat conduction fin 4.Because bent sheet 42 bends to large heat conduction fin 4A front, bent sheet 42 bottom is bending opening 43.In Fig. 8, arrow represents the flow direction of fluid.Fluid in the process of flow forward will inevitably or directly, or change flow direction from encountering bent sheet 42, heat conduction fin 4, iron dividing plate 36 or iron square tube 3 after bending opening 43 passes, after multiple impacts heat exchange, fluid just passes through fluid passage.Fluid by the process of little heat conduction fin similarly.Each collision is all heated fluid.Because having multiple heat conduction fin in iron square tube, each heat conduction fin having and arranges bent sheet more, often arranging bent sheet has multiple bent sheet, and therefore after heating for multiple times, final fluid temperature (F.T.) can reach more than 250 DEG C.Fluid is often many, and by a fluid passage, the number of times collided with bent sheet doubles, and can improve final fluid temperature (F.T.), shortens the heat time.
The preparation method of described electromagnetism heating equipment is that fluid of burn-oning at the iron square tube two ends of described electromagnetic heater enters pipe and goes out manage with fluid, or fluid of burn-oning at the two ends of Electromagnetic Heating unit enters pipe, fluid goes out to manage and return bend, namely makes electromagnetism heating equipment.
