The US patent No. my% issued to Jullan et al. is a typical invention using resistive earth heating. The patent describes a resistance of a thick film heater with a σ-transfer brush on the surface of a cylindrical substrate. The ohmic losses of the traces generate thermal energy. The thermal energy generated by the ohmic loss is transmitted to the sleek plastic in a nozzle to keep the plastic free flowing. Resistive heaters, although at a lower price, have several major drawbacks. Strictly matched with the variance, hot spots, oxidation of the coil, and slower temperature rise are only a few of them. In this case, the large heating power cannot exceed two (lR(max)) XRc ', where 1R(max) is equal to the maximum current that the resistance wire can carry. 'The resistance of the RC system coil.

The inductive heater coil 36 basically comprises a hollow copper member, the outer surface φ of which is provided with an electrically insulating coating 18, and the cooling fluid 39 flows within the tube. Cooling fluid 39 can flow to a cooling system 38 which removes the heat from the inductor to heat in coil 36.

Inductive heating is a method of heating a conductive material by alternating current (A C). We can apply an alternating current to a conductive coil (such as copper) to produce an alternating magnetic field. The alternating magnetic field induces an alternating voltage and current in a workpiece that is tightly coupled to the coil. This alternating current will create a resistive loss and heat the workpiece. Therefore, an important feature of inductive heating is that the heating element can transfer thermal energy to the conductive material without directly contacting the workpiece. When an alternating current is passed through a coil, a magnetic field that varies with the amount of current is generated. If a conductive load is placed in the coil, an eddy current will be induced inside the load. The direction of flow of the eddy current is opposite to the direction of current flow within the coil. The induced current in the load will produce a magnetic field that is opposite to the magnetic field generated by the coil to prevent the magnetic field from penetrating into the center of the load. Therefore, the eddy current is concentrated on the surface of the support body and is sharply reduced toward the center. As shown in Fig. 3A, the inductor heater coil 36 is wound around a cylindrical heat receiving body 20. The current density Jx is indicated by line 41 in the figure. This phenomenon causes almost all current to be generated in the region 22 of the cylindrical heat receiving body 20, and the substance 24 contained in the center of the heated body is not used for heat generation. This phenomenon is often referred to as the "surface effect." In this technique, the depth at which the current density in the load body drops to 37% of its maximum value is called the penetration depth (5). We can assume that all currents in the load are within the penetration depth and are used as a simplification. This simplification assumption helps to calculate the resistance of the current path in the load. The load body has an inherent resistance to the current, so heat is generated in the load. The amount of heat generated (Q) is the resistance (R), the eddy current (1) squared, and

In the design of inductive heating systems, penetration depth is one of the most important factors. The general formula for penetration depth 5 is: where ~= vacuum permeability coefficient Μ = relative magnetic permeability of the load Ρ = resistivity of the load / frequency of the alternating current so the 'penetration depth is a function of the three variables, Two of the variables are related to the load. These variables are the resistivity ρ of the load, the magnetic permeability μ of the load, and the frequency of the alternating current in the coil. The magnetic permeability of the vacuum is constant, equal to 4ττ xl (T7 (Weber/ampere meter). One of the main causes of the different depth of the tooth depth is how much current will flow through the body of a given size. The heat energy generated is related to the square of the eddy current (Ρ). 'We must try to increase the amount of current in the load. In the prior art, the induction heating coil consisted almost exclusively of a hollow copper tube and cooling water flowing inside the tube. The induction coil is the same as the resistance heater, and it shows a certain degree of lightning I: and the heat generation force of the gentleman and the gentleman. This phenomenon is not the property of the coil that affects all the properties of the coil, and 'when the heat inside the coil When it is raised, see 'Because the heat accumulated in the coil directly affects the efficiency of the heater. In addition, the life of the coil is severely limited. Therefore, the oxidizing fluid transfer medium of the coil material will also be promoted, and the heat energy will be converted from the unused heat. The practice used in the prior art is to use the _ induction coil to extract. According to the prior art,

In a preferred embodiment, the heater coil 52 is made of a solid metallic material such as copper or other non-magnetic conductive and thermally conductive material. Alternatively, the coil can be made of a high resistance, high temperature alloy. The use of conductors with low electrical resistance increases the electrical inductance' and thus facilitates some applications in heating. Stranded enameled wire _ :-) is a metal wire construction suitable for low resistance coils. Depending on the design, the texture of the wire and the wire can minimize the energy loss of the solid conductor due to surface effects. Surface effects are the tendency of high frequency currents to concentrate on the surface of the conductor. The lacquered wire can counteract this effect by increasing the surface area without significantly increasing the size of the conductor. The stranded enameled wire consists of thousands of thin copper wires, each of which has a diameter of about OG (H-inch, and each wire strand is provided with an electrical insulator, so that each strand becomes a separate conductor. ^ The inner Ying 49 constitutes a transmission a channel 58 of a fluid (or solid) material to be heated.

A source of alternating current (not shown) having a suitable frequency is coupled in series with coil 52 to pass current through the coil. In a preferred embodiment, the frequency of the current source is selected to match the physical design of the heater. Alternatively, the frequency of the current source can be fixed (preferably around 50 to 60 Hz to reduce the cost of the heating system) while correcting the size of the core 48 and/or yoke 5 〇 and the heater coil μ, This particular frequency and most efficient heater.

The diameter and wall thickness are selected so that the efficiency of the heater reaches the maximum possible. The diameter and wall thickness also determine the coil diameter with the best efficiency. We can follow the method described below and according to a specific heater design.

The sleeve 216 can be attached to the barrel portion 2〇2 in a shrink fit manner, thereby stabilizing the electric component into the human groove m. Alternatively, sleeve 216 can be: a c-shaped portion that is then clamped into one piece. However, it has been found that the electrical component 212 can remain in the trench 214 without the sleeve 216. The sleeve 216 is possible but not necessarily subjected to the force generated by the material handled in the barrel assembly 2 - significant radial load. As shown in Figures 7 and 8, the sleeve 216 can be very thin (relative to the barrel portion 2〇2) and may only be used to secure the electrical component 212. As shown in Figure 9, the sleeve 216 can also have a substantial thickness, with a substantial radial weight. Here, the thickness of the sleeve in the <column is about the same as the barrel portion 202. This particular example places the component 212 deeper within the wall of the barrel assembly 200. The advantage of this _ position is that we can use the inductive energy to heat the barrel assembly 2〇〇 more efficiently because of the electrical components.

Referring to Fig. 10, in another example of the wood in the day of the moon, the electrical component 212 can be placed in the lining 204. The advantage of this embodiment is that the tubular portion 2〇2 having the structural function can be kept smooth without the need to provide a groove which can cause stress concentration. The lining 204 can be a tubular member and has a helical groove in which the electrical component 212 can be mounted. The portion of the barrel portion that covers the electrical component 212 is similar to the sleeve 216 of the previous specific embodiment. - an alternative method is to make the electrical component 212 into a coil shape and mount it on the inner surface 25 of the core 2〇2 and then 'on the electric +, the surface 250' - a suitable wear-resistant gasket material ( For example, through the 埶: coating technique to form a lining...accumulated to a sufficient thickness, the inner surface of the lining: can be formed after processing - a smooth hole to facilitate passage of the flowable material in the barrel assembly.

As with the previous specific example, a sleeve 216, as desired, can be used to secure the electrical component 212 in the channel 214. The specific example shown in Figure 12 can provide similar advantages. In this specific example, the member has no grooves. The electrical component 212 is coupled to a spacer 232, i.e., on the barrel portion 202, and after being compressed, substantially conforms to the space between the spacers 232. For example, spacer 232 can be an annealed ferromagnetic material, and is preferably selected from the same family of cores 202. In this embodiment, the electrical component 2 12 and the spacer 232 are preferably fastened to the barrel portion 2〇2 by the sleeve 21 6 so that the spacer and the electrical component are sandwiched between the sleeve and the core. between. In another embodiment shown in FIG. 13, the outer surface 220 of the barrel portion 202 has a groove 214 therein, but the depth of the groove 214 is insufficient to substantially flush the outer surface 218 of the electrical component 212 with the outer surface 220. The groove 214 can engage a portion of the perimeter of the sheath 228 and preferably has a sheath 228 that conforms to the contour. The extent of the circumferential engagement of the grooves 14/, 4 can be just over 1 degree, causing the sheath 228 to snap into the groove 214 and thereby secure it. The magnetic circuit in this specific example is closed by a sheath. Since the sheath 228 is very thin, the magnetic field will concentrate within the sheath and inductive heat cannot be generated in the barrel portion 202 in an efficient manner. Moreover, since the sleeve is not used in this particular embodiment, the significant electrical resistance heat generated by the electrical component 212 will be radiated to the air or applied to the insulating layer on the barrel assembly 2 as needed. This specific example is the simplest in construction (because there is no liner and no sleeve, and the depth of the groove 214 is the smallest), but it is the least efficient. To improve the performance of this particular embodiment, a cover may be placed on the outer surface 22 of the electrical component 212 and the body portion 2〇2 to a thickness that exceeds one-half the diameter of the electrical component 212. The cover O:\89\89383 D〇c -24^ 1254598 The cover is preferably a metal composite, sprayed). ...the technique known to the public (for example, the hot one alternative method is to mount the electrical component 2ί2 on the un-grooved barrel portion 202) and then set the metallic alloy covering, and fix the electrical component to the desired position. And improving the performance. In all of the above specific examples t, the electrical component 212 can maintain a plurality of axial spacings by a metallic structure disposed therebetween. The metallic structure between the electrical components 212 is preferably about the same as the electrical component. The width of 212 is equal. The electrical components 212 can be placed together in a tight manner to increase the heating density of the barrel assembly 2, but this will concentrate the magnetic field between the electrical components 212, thus generating our Unpleasant thermal gradients and reduced heating efficiency. It is preferable to adjust the frequency and power supplied to the electrical component 212 to achieve the desired heating effect, rather than the spacing between the electrical components 212. The electrical components 212 can be wider. However, the heating density is reduced, and it may be necessary to increase the current and/or frequency to complement the larger power requirements of the electrical component 212. All of the above specific examples use a separate electrical component 212. However, Figure 14 does not.

Referring to Figure 15, the thin film technique can be used to place the electrical component on the smooth outer surface 220 of the barrel portion 202 rather than in a groove. In this specific example, the electrically insulating layer 240 is attached to the entire outer surface of the barrel portion 2〇2. Heating element 242 is then deposited (preferably in a spiral form) on insulating layer 240 to form a coil. A second insulating layer 246 is then placed over the entire surface. This layer may be the final peripheral layer in the previous embodiment; or an intermediate layer by which additional heating elements are deposited on its top surface (preferably as shown, aligning the previously deposited heating elements to Form a multilayer coil). We can repeat this process until the desired thickness is reached. Then, a final outer insulating layer 244 can be provided with a mechanism to sigh the various thin tantalum deposition techniques described above, and the heating 7C member 242 can still be provided by the method. The applied material can be formulated to provide a resistivity factor that provides optimum resistance and inductive heating for a specific frequency and power.
