Abstract
The utility model discloses a low-temperature liquid thermostat bath, including a working bath body which consists of an inner layer bath body and an outer layer bath body, a liquid driving pump and a heat exchanger, the heat exchanger consists of an outer layer shell body and a fluid guide pipe which is arranged in the shell body, a heater is arranged in the fluid guide pipe, the inner layer bath of the working bath body is communicated with the fluid guide pipe by a pipeline, the outer layer bath of the working bath body is communicated with an input interface of the liquid driving pump through another popeline, an outlet interface of the liquid driving pump is communicated with the outer layer shell body of the heat exchanger through a pipeline, and a jet flow stirring nozzle is connected on an outlet of a pipeline which enters the bottom part of the inner layer bath body. The heat exchange of the liquid is completed in the heat exchanger which is communicated with the working bath body; the utility model has smaller liquid volume, which can reduce the volume by about 50 percent under the same size of the working bath body. By adopting the jet flow stirring technology, with no mechanical movement stirrer in the working bath body, the utility model can obtain the higher indicators of the stability and uniformity of the temperature field. The utility model can achieve the water temperature of 100 DEG C without the boiling under an atmospheric pressure.
Description
Technical field
The utility model relates in temperature calibrating, calibration experiment chamber and is used for comparing accurate platinum resistance thermometer, thermocouple thermometer, mercury and other temperature sensors of high precision, and can be used for the long preservation after the water triple point bottle freezes system; Gallium three phase point (the molten point of gallium) keeps the cryogenic liquid thermostat of constant temperature.
Background technology
The liquid thermostatic bath that China and countries in the world production is at present used as shown in Figure 2.Constitute by outer cell body 1, interior cell body 2, heater 3, agitator 4 and motor 5, adopt the liquid thermostatic bath of this structure to have following defective:
1. the heat exchange of liquid, stirring are all finished in a container.
2. in order to obtain warm preferably field stability, uniformity, and need to increase liquid capacity.
3. the increase of volume strengthens energy consumption, and the lifting/lowering temperature time is long.
4. in same container, finish heat exchange owing to there is heating (cooling) element of high power density,
Make warm field uniformity be difficult to guarantee.Stir yet need to strengthen, introduce noise.
The utility model content
The technical problems to be solved in the utility model is, a kind of cryogenic liquid thermostat that overcomes above-mentioned defective in the prior art is provided, this thermostat can not only reduce liquid capacity and machine volume widely, and can improve the warm field uniformity and the stability of work cell body inside, thereby reduce noise and energy-conservation.
The utility model adopts following technical scheme to solve above-mentioned technical problem: construct a kind of cryogenic liquid thermostat, comprise by interior, the work cell body that outer double-deck cell body constitutes, liquid driving pump, also comprise a heat exchanger, described heat exchanger is by outer casing and place the mozzle of housing to constitute, in mozzle, be provided with heater, the inner layer groove of described work cell body is communicated with described mozzle by pipeline, the outer groove of described work cell body is communicated with the input interface of liquid driving pump by another pipeline, the output interface of described liquid driving pump is communicated with the outer casing of described heat exchanger by pipeline, is connected with jet and stirs nozzle on the pipe outlet of the bottom that enters described internal layer cell body.
Adopt the cryogenic liquid thermostat of said structure to have following advantage: the heat exchange of liquid be with heat exchanger that the work cell body is communicated with in finish; Has less liquid capacity, to such an extent as under identical work cell body size, can reduce volume about 50%.Adopt the jet stirring technique, no mechanical motion agitator in the work cell body.Obtain higher warm field stability, uniformity index easily.Can be implemented in an atmospheric pressure is issued to 100 ℃ of water temperatures and does not seethe with excitement.Low noise and energy-conservation.

The specific embodiment
As shown in Figure 1, in the cryogenic liquid thermostat comprises, outer double-deck cell body 12, the 11 work cell bodies that constitute, liquid driving pump 19, other is provided with a heat exchanger, heat exchanger is by outer casing 17 and place the mozzle 16 of housing 17 to constitute, in mozzle 16, be provided with heater 15, the internal layer cell body 12 of work cell body is communicated with mozzle 16 by pipeline 20, the outer cell body 11 of work cell body is communicated with the input interface of liquid driving pump 19 by another root pipeline 14, the output interface of liquid driving pump 19 is communicated with the outer casing 17 of heat exchanger by pipeline 18, and the pipeline exit in the bottom that enters internal layer cell body 12 is connected with jet and stirs nozzle 13.
Fluid stirs nozzle 13 ejections from the bottom jet after entering internal layer cell body 12 bottoms by pipeline 20, produce rotation and rise and stir stream and after the 12 top overflows of internal layer cell body, prolong the refluxing opening that space between the inside and outside cell body flow to outer cell body 11 bottoms downwards, suck superchargings after heat (cold) interchanger temperature control is finished a temperature control through 13 ejections of internal layer cell body 12 bottom nozzles again circulates through water pump 19 by pipeline 14.
As shown in Figure 3, can between 60 ° and 180 °, select at the radial distribution angular range that is connected with in the outlet of internal layer cell body 12 bottom pipe between 13,3 nozzles 13 of 3 jets stirring nozzles; The angle of each nozzle 13 and central ray can be selected between 10 ° of degree and 120 °.Normally 3 nozzles 13 radially are hexagonal angle and distribute, each nozzle becomes 75 ° of angle settings with central ray, can form brute force and spray stirring stream, rotates thereby liquid is risen.Fluid driven pumps 19 is provided with the third gear speed governing, and the user can adjust the utility model as required and utilize space formation liquid circulation loop between the inside and outside layer cell body, makes it to separate the thermal loss that conducts heat and produced between cell body and the air, a minimizing level temperature thermograde.Heat exchange is placed the cell body outside, make the inner no thermal source of cell body, thereby improved temperature stability, uniformity index.Heat exchange is to carry out under greater than an atmospheric pressure, thereby makes that can rise to 100 ℃ when making water as medium does not seethe with excitement.The system fluid that provides low noise, adjustable speed, a no leakage liquid driving pump needed power that circulates is finished multi-functionals such as heat exchange, stirring.The utility model has not only overcome the shortcoming that exists in the prior art, and all is being better than aspect the technical indicators such as fluid displacement, complete machine size, energy consumption, noise, temperature control stability, warm field uniformity
Prior art.
