Description
Technical field
The utility model belongs to electrical heating technique field, and specifically, the utility model is related to a kind of electromagnetic induction heating bodies
And the electromagnetic induction heating heater containing it.
Background technology
Electromagnetic induction heating heater is a kind of device of the principle progress heating using electromagnetic induction.Its groundwork is former
Reason is high-frequency alternating current (20000Hz or more) to be provided by drive control unit for the coil being wrapped on heating water pipe, 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 efficiency of heating surface is high, fast and easy start and stop.However, recirculated water, in Bottomhole pressure, Temperature Distribution is simultaneously uneven
It is even.Fluid outside runner can be initially heated, and heat is gradually diffused by heat convection in the middle part of runner again.In runner
In the case of the main body water flow temperature still relatively low (being only slightly higher than inlet temperature) in centre, close to the fluid temperature (F.T.) of tube wall
It can acutely increase.For the electromagnetical heating heater that power is larger, the fluid temperature (F.T.) close to tube wall even can 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 drastically 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 but increases rapidly,
It is serious material at high temperature to be caused to destroy.
Prior art mainly carries out overheat protector by monitoring the temperature of tube wall.When tube wall temperature is close to the boiling point of water
When, control system can cut off coil power.This method can effectively prevent tube wall to vaporize, and protect 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, the system that only overheat protector controls
Can cause in the case that mean outlet temperature increase it is limited, electromagnetic induction heater be just often forced to frequently, for a long time stop
Work, causes electromagnetic induction heating technology to be unable to give full play the high advantage of its rate of heat addition.

The utility model is introduced in electromagnetic induction heating body for insert in the pipe of fluid-mixing and augmentation of heat transfer, and
The insert mounting hole 6 in the end set pipe of heating pipe can be such that insert in pipe is fixed below pipeline (fixed)
Or (self-rotary) is connect with the bearing of pipeline lower part.
Insert is a kind of component for one-way flow heat transfer in enhanced tube in pipe.Preferably, insert includes knob in managing
The multiple types such as belt (fixed or self-rotary), static mixer, conical ring, star insert, helical spring.It is inserted into 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), generate vortex so that center flow channels fluid and wall surface fluid sufficiently radially mix in pipe, reduce boundary layer thickness, reinforce 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, much higher heat exchange system can be possessed by being equipped with the pipeline of insert in pipe
Number, while can vaporize to avoid wall flow body, heat transfer deterioration occur and the phenomenon that temperature is ascended to heaven.
Much higher heating power can be obtained by being equipped with the electromagnetic induction heating body of insert in pipe.On the one hand, pass through
The temperature for reducing near wall fluid, can improve heat transfer temperature difference, to improve heat exchange amount；On the other hand, heating power not
In the case of 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 interval starts in this way, when raising equal heating power.Cause
This, manages interior insert and may be implemented to improve the function of the electromagnetic induction heater entirety rate of heat addition.
, can be limited in flow resistance increase by being inserted into species type and model in the suitable pipe of selection, greatly
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.The heating of whole heating circulation waters can be quickly completed, properties of product are substantially improved in a short period of time.
The fluid for being enhanced electromagnetic induction heating heater using insert in pipe is mixed, and is improved the whole efficiency of heating surface, is reduced
Overheat protector initiation culture.
