Abstract

The utility model discloses an electromagnetic heat exchanger, which is provided with a flow-guiding pipe 3 with a liquid inlet 1 and a liquid outlet 2, wherein, the outside of the flow-guiding pipe 3 is provided with an insulating layer 4, and the outside of the insulating layer is provided with an electromagnetic coil 5. After the electromagnetic coil is energized, the body of the flow-guiding pipe generates vortex flow, and the temperature of the flow-guiding pipe is quickly raised to heat the fluid in the flow-guiding pipe. Meanwhile, a strong magnetic field is formed in the flow-guiding pipe to act on the fluid, and the temperature of the fluid is quickly raised. The heat conversion efficiency of the utility model is high, and compared with heat conversion efficiency of heating a product by the existing electrothermal film, and the heat conversion efficiency raises 30 to 40%. The utility model can be sued for the fields of agriculture, aquaculture, seedling cultivation, oilfields, heating, etc.

Description

The electromagnetism heat exchanger

Technical field:

The utility model relates to a kind of heater, and especially a kind of heating fields such as boiler that can be applicable to are converted into electric energy, magnetic energy on the electromagnetism heat exchanger of heat energy.

Background technology:

In the past, many firing equipments were that fuel is realized heat exchange with coal, oil all.Coal-fired, not only heat exchanger effectiveness is low for apparatus for fuel heating, and a large amount of toxic emissions is arranged in the combustion process, therefore, environmental administration has determined to forbid to produce and use small-sized fire coal, oil burning boiler in some city, praises highly the electrical heating product of non-pollution discharge.Shortcomings such as present electrical heating product (electric heater, electric boiler etc.) is generally directly-heated type and heat-storage, and it utilizes electrothermal tube (resistance wire) to heat, and is all big at power consumption, that thermal transition efficient is low, poor stability and reliability are low.Though people have increased the intellectuality control of electrothermal tube heating products in order to reach purpose of energy saving, its energy-saving effect still can not be satisfactory.For this reason, existing another kind of electrical heating product comes out, and promptly is the product of thermal source with the Electric radiant Heating Film.Electric radiant Heating Film heating products thermal transition efficient is than general resistance wire heating products thermal transition efficient height, but owing to be subjected to the restriction of Electric radiant Heating Film coating technique and equipment, be difficult to make stay-in-grade high power electrothermal film heating device, and small power electric hotting mask heating products is also the same with the resistance wire heating products, exist and can not anhydrous dry combustion method reach the easily shortcoming of electric leakage, this also is the main cause that present Electric radiant Heating Film heating products can not be popularized.

Summary of the invention:

The purpose of this utility model is in order to solve the existing in prior technology problem, and a kind of thermal transition efficient height, electromagnetism heat exchanger that reliability is high are provided.

Technical solution of the present utility model is: a kind of electromagnetism heat exchanger, be provided with have fluid inlet 1, the mozzle 3 of fluid issuing 2, described mozzle 3 outsides are provided with insulating barrier 4, the outer solenoids 5 that are provided with of insulating barrier 4.

Described mozzle 3 can be to be provided with parent tube 6, and parent tube 6 communicates with fluid issuing 2, has two-layer bushing pipe 7,8 in the parent tube 6 at least, and an end of bushing pipe 7,8 has plug 9, and bushing pipe 7 communicates with fluid inlet 1, and bushing pipe 7,8 is provided with fluid through-hole 10,11.

Described insulating barrier 4 can be fire-retardant layers of kraft paper.

After special construction of the present utility model makes the solenoid energising, the mozzle body produces eddy current, mozzle is rapidly heated the fluid in the mozzle is heated, simultaneously in mozzle, form very strong magnetic field and acted on fluid, make fluid heat up rapidly, its thermal conversion efficiency is very high, than the thermal conversion efficiency raising 30～40% of existing Electric radiant Heating Film heating products.The utility model have thermal conversion efficiency high in, also have following advantage: electricity separation can make the security of products height; Strong magnetic field action in the mozzle can be avoided the water conservancy diversion in-tube fouling; Various fluids such as available seawater are as heat medium, and the conserve water resource can be widely used in fields such as agricultural, aquaculture are grown seedlings, oil field, heating.

Fig. 2 is the external structure schematic diagram of the utility model embodiment.

Fig. 3 attempts for the A-A of Fig. 1.

The specific embodiment:

Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 2: the utility model embodiment can be provided with have fluid inlet 1, the mozzle 3 of fluid issuing 2, mozzle 3 must be made with iron, its surperficial available macromolecular material carries out preservative treatment, is the needs of seawater etc. with suitable fluid.Fluid intake 1 can arbitrarily be set with fluid issuing 2.In order to make fluid fully magnetization in mozzle 3, mozzle 3 can be as shown in Figure 1: be provided with parent tube 6, parent tube 6 communicates with fluid issuing 2, has two-layer bushing pipe 7,8 in the parent tube 6 at least, one end of bushing pipe 7,8 has plug 9, bushing pipe 7 communicates with fluid inlet 1, and bushing pipe 7,8 is provided with fluid through-hole 10,11.Fluid is entered the bushing pipe 7 from fluid intake 1, enter between bushing pipe 7 and the bushing pipe 8 by fluid through-hole 10, enter between bushing pipe 8 and the parent tube 6 by fluid through-hole 11, fluid flows out from fluid issuing 2 after sufficient heat exchange and magnetization.Can be the real fluid inlet also with the fluid issuing in scheming 2, and the fluid intake 1 among the figure is actual fluid issuing, be that the fluid issuing 2 of fluid from figure enters, by parent tube 6, fluid through-hole 11, fluid through-hole 10, the fluid intake from figure 1 flows out at last.As Fig. 2, shown in Figure 3: mozzle 3 outer will windings have layers of kraft paper fire-retardant, insulation effect, and its thickness is advisable with 3～6mm, and promptly insulating barrier 4.Twine solenoid 5 outside insulating barrier 4, solenoid 5 available epoxy sealing are in the housing that can more whole electromagnetism heat exchanger be placed insulation, ventilates.

Operation principle: after solenoid is connected power supply, baffle made of iron itself produces eddy current, baffle is rapidly heated, fluid in the baffle is heated, simultaneously can in heat exchanger, form a very strong magnetic field, make the fluid molecule strenuous exercise and the collision in this magnetic field of flowing through, produce a large amount of heat energy, electric energy-magnetic energy-heat energy conversion efficient height can be saved a large amount of electric energy.
