Description
Technical field
The invention belongs to electrical heating technique field, in particular it relates to a kind of electromagnetic induction heating body and containing its
Electromagnetic induction heating heater.
Background technique
Electromagnetic induction heating heater is a kind of device of principle progress heating using electromagnetic induction.Its groundwork is former
Reason is that the coil by drive control unit to be wrapped on heating water pipe provides high-frequency alternating current (20000Hz or more), in coil
High frequency changing magnetic field is formed in the space at middle part, forms countless eddy currents in the metal material of water pipe tube wall, generates heat,
To quickly heat the heating circulation water in pipeline.
Compared with other heating equipments, due to direct quickly heating pipeline, electromagnetic induction heating heater has heat
It dissipates less, the advantages that heating efficiency is high, fast and easy start and stop.However, Temperature Distribution is simultaneously uneven when recirculated water flows in pipe
It is even.Fluid outside runner can be initially heated, and heat passes through heat convection again and is gradually diffused into the middle part of runner.In runner
In the case where the main body water flow temperature in centre still lower (only slightly higher than inlet temperature), close to the fluid temperature (F.T.) of tube wall
It can acutely increase.Electromagnetical heating heater biggish for power, the fluid temperature (F.T.) close to tube wall can even be rapidly reached boiling
Point forms vapor bubble even air film on tube wall, causes heat transfer coefficient to become smaller suddenly, heat-transfer effect sharply deteriorates, heat
It can not be carried away by the flow in time, while runner temperature can not increase in time, the temperature of tube wall metal material is but increased rapidly,
It is serious material at high temperature to be caused to destroy.
The temperature that prior art mainly passes through monitoring tube wall carries out overheat protector.When tube wall temperature is close to the boiling point of water
When, control system can cut off coil power.Tube wall vaporization can be effectively prevented in this method, protects pipe wall material.But due to height
The rate of frequency electromagnetic induction coil heating tube wall is significantly faster than the rate that heat is transmitted to runner center from outer layer fluid, in outer layer
When the temperature of fluid is already close to boiling point, the water temperature of pipeline main body may be also very low, therefore, only overheat protector control system
It will cause in the case where mean outlet temperature increases limited situation, electromagnetic induction heater is just often forced to stop frequently, for a long time
Work, causes electromagnetic induction heating technology to be unable to give full play the high advantage of its rate of heat addition.
Summary of the invention
The object of the present invention is to provide a kind of electromagnetic induction heating body, which is followed using insert raising in pipe
The method of ring water outlet temperature and the electromagnetic induction heating heater rate of heat addition, by introducing Radial Flow in Guan Liuzhong, so that

Several magnetizers 7 are set on the outside of radio-frequency induction coil 5, the insertion in setting pipe in the flowing space in the pipe of heating pipe 2
Object 1.
Preferably, insert 1 is bond type insert, static mixer, conical ring, star insert or spiral shell in the pipe
Revolve spring.
Preferably, the quantity of several magnetizers 7 is at least four (magnetizer quantity can also regard watt level as four
Item, six, eight etc.), it is uniformly arranged on radio-frequency induction coil 5.
The present invention also provides a kind of electromagnetic induction heating heater, the electromagnetic induction heating heater includes above-mentioned
Electromagnetic induction heating body.
Further, the electromagnetic induction heating heater further includes heating radiator 11, the heating radiator 11 with
Electromagnetic induction heating body forms heat transfer cycle circuit, and water circulating pump 12 is arranged on the heat transfer cycle circuit；Electromagnetic induction
The radio-frequency induction coil 5 of calandria is connect with driving and control unit 8, and driving and control unit 8 connect alternating current input source 9.
The present invention is introduced in electromagnetic induction heating body for insert in the pipe of fluid-mixing and augmentation of heat transfer, and is being added
The end setting of hot-water line manage in insert mounting hole 6, can make in pipe insert be fixed below pipeline (fixed) or with
The bearing of pipeline lower part connects (self-rotary).
Insert is a kind of component for one-way flow heat transfer in enhanced tube in managing.Preferably, insert includes knob in managing
The multiple types such as belt (fixed or self-rotary), static mixer, conical ring, star insert, helical spring.Insertion in pipe
The water conservancy diversion of object or spin can allow fluid to rotate, and it is (secondary to introduce Radial Flow on the basis of axial flowing (primary stream)
Stream), vortex is generated, so that center flow channels fluid and wall surface fluid sufficiently radially mix in managing, reduces boundary layer thickness, reinforces stream
It conducts heat between body, increases flow distance, accelerate the heat transfer for absorbing near-wall fluid to runner center, realize whole fluids
Quick entirety be evenly heated.Compared to light pipe stream, the pipeline for being equipped with insert in pipe can possess much higher heat exchange system
Number, while heat transfer deterioration can occur and the phenomenon that temperature is ascended to heaven to avoid wall surface fluid vaporization.
The electromagnetic induction heating body for being equipped with insert in pipe can obtain much higher heating power.On the one hand, pass through
The temperature for reducing near wall fluid, can be improved heat transfer temperature difference, to improve heat exchange amount；On the other hand, heating power not
In the case where change, the time of wall portions fluid heating can be slowed down, to postpone time, the extension single heating that vaporization occurs
Heating duration in period.Can reduce the number that overheat protector in the unit time starts in this way, when raising equal heating power.Cause
This, managing interior insert may be implemented to improve the function of the electromagnetic induction heater entirety rate of heat addition.
It, can be in the case where flow resistance increases limited situation, greatly by selecting insertion species type and model in suitable pipe
Width improves heat transfer coefficient, reduces wall surface temperature, while improving heat transfer temperature difference, avoids frequent starting overheat protector.So as to
The advantage of tube wall temperature can be improved rapidly by giving full play to electromagnetic induction heating, greatly improve adding for electromagnetic induction heating heater
The thermal efficiency.Can the heating of whole heating circulation waters be quickly completed, properties of product are substantially improved in a short period of time.
It is mixed using the fluid of insert enhancing electromagnetic induction heating heater in pipe, improves whole heating efficiency, reduce
Overheat protector initiation culture.
