Description

The electromagnetical immediately heating fluid heater

Technical field

The utility model relates to a kind of fluid heater, specifically is to utilize the heating of electromagnetic energy convection cell particularly to the electromagnetical immediately heating fluid heater of water heating, is widely used in family, school, commercial building and other relevant industry.

Background technology

Chinese patent application file (patent No. 200420022392.3) discloses a kind of electric heater.The heating system of this kind water heater comprises the iron core of circular cylindrical shape, be wound on the primary coil on the iron core column limit, cooling water pipe along the external peripheral surface coiling of primary coil, secondary coil one copper pipe on the coiling iron core column limit, the copper pipe two ends connect cooling water pipe and outlet pipe respectively, face mutually between the two circle copper pipes and have the solder joint that can form short circuit, primary coil is by relay and power connection, the primary coil of coiling and along the cooling water pipe of the external peripheral surface coiling of primary coil inclusion in the lump on the iron core.Though this water heater has its unique novel part, yet the part that still haves much room for improvement.The first, the price price of annular core higher (exceeding two times) than E shape iron core unit price; The second, manufacture difficulty big-coiling of primary coil is more loaded down with trivial details, technology difficulty is big, needs the higher import circle of precision around the machine coiling, the price and the maintenance cost of equipment is higher, the product percent defective is also big.Three, the pipeline as secondary coil need be socketed to form, and easily cause the generation of weld seepage phenomenon, and consumptive material is more.Mainly be cost and the process issues in the actual production process,

The utility model content

Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of water heater is provided, its should have simple and reasonable, efficient is higher and easy to manufacture, weight is lighter, lower-cost characteristics.

The technical scheme that the utility model provides is: the electromagnetical immediately heating fluid heater, its heating system comprises iron core, be wound on the primary coil on the iron core, copper pipe along the primary coil external peripheral surface coiling after the insulation processing as secondary coil, the copper pipe two ends connect cooling water intake and delivery port respectively, facing mutually between the two circle copper pipes of secondary coil has the solder joint that can form short circuit, described iron core is that the cross section is the rectangular cylinder of " day " font, this iron core is formed by the butt joint of E type silicon steel sheet, and described primary coil is wound on the newel at iron core middle part.

Be set with skeleton on the newel at described iron core middle part, described primary coil is wound on the skeleton.

Described copper pipe first half is a cooling water pipe, and latter half is the heating pipe who has the short circuit solder joint.

Because the rectangular cylinder iron core of " day " shaped sections adopts the butt joint of E type silicon steel sheet, thereby has annular and the incomparable advantage of 0 shape iron core, 1, use cut-parts formula silicon steel sheet can improve stock utilization, the saving manufacturing cost to greatest extent.2, primary coil and secondary heater coil can be undertaken prefabricatedly by checking the back data, more adapt to scale flowing water and produce and processing.3, coil winding is in prefabricated skeleton, and the line system that holds also becomes more free and relaxed, arranges slyness closely, and insulation processing is more convenient safer.Should be pointed out that at last the utility model more becomes rationally in technology, structure, all many-sides of cost, manufacturing cost has tangible reduction.

The specific embodiment

The whole rectangular shape of the heating system of Fig. 1, this electromagnetical immediately heating fluid heater shown in Figure 2, the rectangular cylinder iron core of " day " shaped sections adopt E type silicon steel sheet to dock.Be inserted in skeleton 4 on the newel 1-1 of iron core 1, even in advance coiling enamel-covered wire as primary coil 2 on the skeleton, the external peripheral surface of primary coil is wound with the copper pipe 3 as secondary coil, the number of turns of primary coil and secondary coil can be determined (also can be without skeleton, primary coil directly is wound on the newel of iron core 1) as required.As the copper pipe 3 of secondary coil, its first half directly connects cooling water intake 3-1 also as cooling water pipe; Latter half is as the heating pipe, and its copper pipe that faces mutually between two circles has the solder joint 3-3 that can form short circuit, and the outlet of copper pipe directly connects delivery port 3-2.

Fig. 3, shown in Figure 4 be that heating system is removed the cross-sectional schematic after prefabricated line holds the group assembly.Among the figure as can be known: the cross section of this iron core is " day " font, adopts E type silicon steel sheet butt joint back.E type silicon steel sheet adopts general slitter just can make.(the line bag is primary coil and secondary heater coil) is integrally welded with core lamination stack with argon arc welding after being inserted in prefabricated line bag; Whole heating system is through carrying out whole package insulation processing with DMC or other insulating materials after the assay was approved.

Fig. 5, shown in Figure 6 be the cross-sectional schematic that prefabricated line holds the group assembly.Among the figure as can be known: innermost layer be skeleton 4, the second layer is a primary coil 2, the nature, primary coil also can be shaped on some tap 2-1.The 3rd layer is that 5, the four layers of insulating materials are the secondary coils 3 as fluid heating usefulness.The course of work of the present utility model is: when opening water flow switch, the primary coil energising produces magnetic field, responds to short circuit current as the copper pipe of secondary coil latter half because of generation and heats up.Current enter from water inlet 3-1, the cooling water pipe that flows through the first half of secondary coil earlier carries out preheating cooling (the not short circuits of copper pipe between two circles), when water continues to flow through copper pipe between two circles when position of short circuit is arranged, current are heated, flow out from delivery port 3-2 at last, finish whole heat cycles.

During the primary coil coiling, its line footpath should be decided according to the designing requirement checking computations of product with the number of turn, and can carry out the multichannel tap as requested, so that the control of power and selection.

When making secondary coil winding (short circuit heating tube), should be close to the elementary winding after insulation is handled as far as possible.Secondary windings adopts the low resistance conductor material, as red copper matter etc.Can use welding procedures such as soldering, fine weldering, argon arc welding at the position that needs short circuit, also can adopt other technology to make its short circuit.Processing technology and pipeline shape are varied, but no matter adopt which kind of technology and shape, allly can make all can of secondary coil turn-to-turn short circuit.Its operation principle is close with transformer in a word, and difference is secondary.
