Abstract
The utility model discloses a constant temperature bath which is designed according to the heat pipe principle. The temperature field distribution of the utility model can satisfy requirements which are calibrated or certified by a mercury thermometer with the first and second class standard. The utility model is also universal for the calibration or the certification of industrial and experimental glass thermometers (precision thermometers and common thermometers). The utility model is composed of a radial temperature equal heat pipe, an outer shell and a base provided with a rotating disk. The temperature can be controlled within the design temperature between 75 DEG C and 250 DEG C by an external connection precise temperature controller. The temperature can be rapidly lowered. Eight thermometers can be calibrated or certified for one time.
Description
The utility model is a kind of novel constant-temperature groove, demarcates or the calibrating use at 75 ℃ of-250 ℃ of warm areas for glass-stem thermometer.
Existing thermometer is demarcated or the calibration cell of calibrating usefulness is the CS604 standard oil tank, and not only volume is big for it, and constant temperature speed is slow, and oil vapour is serious, and contaminated air smokes the laundry damage health.
Task of the present utility model adopts " heat pipe " technology that newly-developed gets up in the thermal conduction study field, uses a kind of brand-new principle and structure, for glass-stem thermometer is demarcated or calibrating provides that a kind of volume is little, constant temperature is fast, free of contamination calibration cell.According to " metering appliance detecting rules " the temperature regulation to constant temperature, the utility model is applicable to first-class standard mercury thermometer, second-class standard mercury thermometer, industry and the precision glass thermometer of experiment usefulness and the demarcation or the calibrating of simple glass thermometer.
The utility model is realized by heat pipe principle, the survey pipe conduct of laying temperature meter is the condensing zone of isothermal heat pipe radially, hold survey pipe cylindricality airtight container wall as the heating zone, with water is working medium, water is heated gasification at the container wall, and Radial Flow is to surveying on the tube wall, steam is caught a cold and condensation at survey pipe outer wall, condensed fluid returns container bottom by action of gravity, rise on the chamber wall by capillary action by the imbibition core that is contained on the container inner wall again, and be heated vaporization, formed characteristics of the present utility model like this: by the phase transformation of working medium and the mobile transmission heat of steam.Be in the saturated vapour owing to survey pipe, and the heat flow density of output is very little, thereby surveys the surface that is in control the height isothermal, realized the constant temperature function that large-scale oil groove reached.
Fig. 1 is according to the calibration cell sectional view that the utility model proposes.
With reference to Fig. 1, in calibration cell, comprise a radially isothermal heat pipe (1), the survey pipe (2) that the laying temperature meter is radially arranged in the isothermal heat pipe, surveying pipe (2) makes with thin-wall copper pipe, survey pipe (2) soldering on the top cover of cylindricality closed container (3) for nine, the material of container (3) is made of copper-stainless steel composite material.Medial surface at cylindricality closed container (3) posts the imbibition core made from copper mesh (4), imbibition core (4) is full of hole, the mat capillary action promotes working medium (6), container (3) outside surface is tied with well heater (5) and refrigeratory (8), and well heater (5) is controlled by external precision temperature controller.Container (3) bottom be equipped with fill working medium (6) fill pipe (7), whole radially isothermal heat pipe (1) is contained in the shell (9), is the heat insulation layer (10) of filling aluminosilicate fiber cotton thermal insulation material therebetween.Whole casing body (9) is installed on the base (13), by handle (11) housing is gone up at base (13) and is rotated, determine angle by index dial (12).The calibration cell device size is about φ 150mm * 700mm(diameter * height).
Claims (7)
