Description
Technical field
The present invention relates to a kind of temperature balancing device, in particular, it is to be related to one kind to be used for balancing pid heter temperature
The device of fluctuation.
Background technology
In a lot of fields it would be desirable to carry out temperature control to fluids within pipes medium, majority of case is to need to manage
In road, the temperature stabilization of fluid media (medium), in some definite value, now often adopts pid temperature control technology, by pid automatic warm
The adjust automatically of heater power realized by control table, so that medium temperature is stablized near setting value.Control skill yet with pid
The limitation of art itself, and affected by pipeline local environment, in pipeline, the temperature of flow media can not possibly keep one absolutely
To definite value, but present the trend fluctuating up and down around setting value, the amplitude of fluctuation and concrete control mode and concrete ring
Border situation is relevant, often at least positive and negative 1 degree of wave amplitude, even more greatly.Needing the occasion of accurate temperature controlling, this temperature fluctuation
It is unacceptable, such as, in plastics-production industry or laboratory accurate temperature controlling occasion, the fluctuation of temperature very little may be led
The decline of product quality or the uncertainty of experimental data is caused to sharply increase.Traditional way is to install after pid heater
Thermostatic water bath or oil groove carry out further temperature constant, or directly pass through thermostatic water bath or oil groove heating fluid.Constant temperature
Oil groove, tank realize high (± 0.001 DEG C) water temperature of precision and oil by special accurate heating, cooling, thermometric, control parts
Temperature control system, external pipe fluid flows through thermostatic water bath, oil groove by coil pipe.
Cross thermostatic oil bath or tank realize accurate temperature controlling face equipment take up space, the problem of high cost, powerful perseverance
These problems of warm water tank or oil groove are more prominent, and the water of thermostatic water bath, oil groove and oil are often in fixed space, outside stream
Body needs by the just heat exchange of special coil pipe, installs inconvenient.
Content of the invention
The invention aims to overcoming deficiency of the prior art, one kind is provided to be used for balancing pid heter temperature
The device of fluctuation, this device inputs without external power source and power, realizes automatically putting down of temperature by the mixing of fluid itself
Weighing apparatus, it is simple to have a structure, easy to use, the advantages of cost-effective good balance effect.
The purpose of the present invention is achieved through the following technical solutions:
A kind of device for balancing the fluctuation of pid heter temperature, described device is made up of cylindrical mixing chamber, described mixed
The wherein one end closing room is provided with fluid outlet, is respectively arranged with connecting hole, institute at the upper, middle and lower position of described mixing chamber
State connecting hole to be connected with the isocon one end being wrapped in mixing chamber outer wall respectively, the other end of described isocon is connected with fluid
Input port, described mixing chamber is additionally provided with thermocouple interface.
Described mixing chamber and isocon are each made of a metal.
Described mixing chamber and isocon are made by copper material.
Described connecting hole is elliptical openings.
Described connecting hole is connected by welding manner with isocon.
Compared with prior art, technical scheme is had the benefit that
1st, three isocons of the present invention are all wrapped on mixing chamber, by isocon and the heat exchange mixing chamber outer wall, real
The first time balance of existing temperature fluctuation.
2nd, mixing chamber cavity volume of the present invention is more than the flow in one period of waves of fluid temperature (F.T.), indoor in mixing, stream
Body passes through and is sufficiently mixed, by convection current and heat conduction so that periodic temperature fluctuation greatly reduces.
3rd, in the present invention, three isocons connect in mixing chamber upper, middle and lower three position respectively, flow in three isocons
Approximately equal.Three road fluids enter mixing chamber by diverse location, strengthen fluid in the indoor disturbance of mixing, thus strengthening temperature
Counterbalance effect.
4th, in the present invention, three isocons are connected with the connecting hole of mixing chamber by welding manner, and connecting hole is in ellipse
Shape, fluid approximately enters mixing chamber from tangential direction, thus in mixing indoor formation vortex, strengthening mixing effect of fluid, thus
Strengthen hygral equilibrium effect.
Brief description
Fig. 1 is the structural representation of the present invention under different directions.
Fig. 2 is to be provided without the experimental data curve figure that apparatus of the present invention carry out hygral equilibrium.
Fig. 3 is the experimental data curve figure carrying out hygral equilibrium using apparatus of the present invention that mixing chamber volume is 0.25l.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of device for balancing the fluctuation of pid heter temperature, described device is by cylindrical mixing chamber 1
Constitute, wherein one end of mixing chamber 1 is provided with fluid outlet 7, mixing chamber 1 is respectively arranged with top connecting hole 2, middle part connects
Connect hole 3 and bottom connecting hole 4, this three connecting holes are connected by welding manner with three isocons 5 respectively, soldering opening is in ellipse
Shape；This three isocon 5 sectional areas are identical, and length differs, and three isocons 5 are spirally wrapped around on the outer wall of mixing chamber 1,
Linking together with fluid input port 6 of final convergence, is additionally provided with thermocouple interface 8 on mixing chamber 1 in addition.
When the present invention is embodied as, fluid is divided into three identical section by three isocons 5 after passing through fluid input port 6
Unequal three streams of area, length.Three isocons 5 pass through connecting hole 2,3,4 " incision " mixing on mixing chamber 1 respectively
The internal cavities (isocon 5 end and mixing chamber 1 radius near normal) of room 1, fluid is defeated through fluid after mixing in mixing chamber 1
Outlet 7 output.
As shown in Figure 2 to Figure 3, experiment condition is: discharge is 80l/h, and pid controls electric heater, and (phase-shifting trigger sets
Water temperature is 39 degrees Celsius), 8 degrees Celsius of tap water is heated, Fig. 2 is that the change of water temperature when not using any device is bent
Line is it is seen that the maximum amplitude that water temperature fluctuates near 39 degrees Celsius up and down has reached 2 DEG C of even more highs；And in Fig. 3 and Fig. 4, when
Install mixing chamber 1 volume be this device of 0.25l or 0.5l after, upper and lower fluctuation range is significantly near 39 degrees Celsius for water temperature
Reduce and tend to be steady it is seen that using after apparatus of the present invention, temperature fluctuation amplitude can greatly reduce, effect is significant.
