Compared with the conventional heat pipe thermostatic bath, the heat pipe thermostatic bath in the utility model has the advantages of remarkably improved stability and uniformity of temperature field and thermostatic effect, low electric energy loss and good temperature control effect; and can meet the verification, calibration and testing requirements of various temperature elements and meters.
Description
Technical field
The utility model relates to a kind of heat pipe thermostatic bath, belongs to the thermostat in temperature measurement/calibration field.
Background technology
Heat pipe thermostatic bath is a kind of thermostat that utilizes heat pipe principle to make, and uniform temperature field distribution characteristic can be provided in certain temperature range, is used for calibrating, calibration, verification thermal resistance, thermocouple, all temps meter or sensor.According to the difference of charging into working media, the operating temperature range commonly used of heat pipe thermostatic bath has: 50 ℃～150 ℃, 150 ℃～300 ℃, 300 ℃～500 ℃ etc., the main distinction of all temps scope heat pipe is the difference of working media.The heat pipe thermostatic bath that present stage adopts, under the sensor insertion depth situation of more shallow (as less than 150mm), warm field uniformity is not ideal enough, and there are bigger measure error in calibrating, the short type element of calibration when more shallow (or element insertion depth).
Summary of the invention
For solving the problem of above existence, the utility model provides a kind of new heat pipe thermostat, and its technical scheme of taking is:
This heat pipe thermostatic bath comprises radiator, heat pipe tube core, is located at sensor intubate in the heat pipe tube core and the electrothermal tube that is positioned at the heat pipe die bottom, sealing is connected to form the condensing reflux passage between radiator and the heat pipe tube core, and the radiator present position is higher than heat pipe tube core upper end.
Radiator exceeds heat pipe tube core upper end in vertical direction, with the heat pipe upper end cover to the condensing zone of radiator top as heat pipe, the whole part that is positioned at inside heat pipe of sensor intubate all is in isothermal region, compare with present existing heat pipe thermostatic bath, improved the upper temp distributing homogeneity of heat pipe thermostatic bath greatly.
Around the sensor intubate exposed parts that is positioned on the heat pipe upper end cover, be laid with electric heating device, to remedy the loss of this place's heat.
The radiator outer surface is wound with condenser pipe, can cool off the requirement of fast cooling when satisfying pressure-type thermometer to temperature switch, charged contact, the instrument calibration/calibration of bimetallic thermometer equitemperature/test by cooling water opposite heat tube thermostat fast.
Electrothermal tube in the heat pipe tube core is combined by the heating of two different capacities, under different duties, independent power supply or string and tandem compound by two heatings, can change the rated power of heat pipe tube core, heat up, be incubated the power compatibling problem under two kinds of duties to solve.
Therefore the beneficial effect that the utility model had is: this heat pipe thermostatic bath temperature field stability, the uniformity and the more conventional heat pipe thermostatic bath of constant temperature effect are significantly improved, it is effective to save electric energy loss and temperature control, can satisfy the calibrating/calibration/test request of all temps element, instrument.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, a plurality of sensor intubate 2 are located in the heat pipe tube core 1, and the heat pipe end face that is covered by heat pipe upper end cover 8 is exposed on its top a little, are laid with electric heating device around sensor intubate 2 exposed parts on heat pipe upper end cover 8.Electrothermal tube 6 is installed in heat pipe tube core 1 bottom, and it is combined by the heating of two different capacities, and electrothermal tube 6 is connected with power governor through electrothermal tube terminals 7.Heat pipe one side or the left and right sides are provided with radiator 4, and radiator 4 exceeds heat pipe tube core 1 upper end in vertical direction, and sealing is connected to form the condensing reflux passage between it and the heat pipe tube core 1, and outer surface is twining the condenser pipe by the metal tube coiling.Liquid refrigerant 3 is distributed in around the metal catheter of electrothermal tube 6 and Pressure gauge 5, and heat pipe integral body is wrapped up by insulation material.
When work, the element that needs to examine and determine, calibrates or test is inserted in the pore of sensor intubate 2, set temperature required, under the control of temperature control instrument and controller, electrothermal tube 6 heating liquid refrigerants 3 are to evaporation, carry the steam flow heat pipe top of heat, and heat outwards distributed by tube wall, make the whole part that is positioned at inside heat pipe of sensor intubate all be in isothermal region, steam mainly is condensed into liquid at radiator 4, get back to the thermal treatment zone along the condensing reflux passage, be heated once more, evaporate.By the FEEDBACK CONTROL of temperature control instrument, make the temperature of heat pipe isothermal region keep constant temperature.
For making heat pipe thermostatic bath heat up, be incubated under the two states and work better, can adopt following scheme:
Scheme one: the combination with electrothermal tube is made two kinds of different capacity heatings, switch to high-power heating element heater during intensification, to guarantee programming rate, switch to the small-power heating element heater during insulation, with the step resolution and the dynamic range of guaranteed output adjusting.
Scheme two: only use high-power heating element heater, during intensification with the power supply of 220V power supply as power regulator, pass through step-down transformer during insulation, provide low-voltage to power regulator, the electricity scope is looked heat pipe different temperatures scope with design temperature and different, generally between 30V～110V, can meet the demands about transformer capacity selection 250VA, for exceeding transformer secondary output output voltage or capacity, can directly use the 220V power supply.
