Abstract
The utility model relates to an improved version constant temperature water bath device comprising a heat source device, a water bath, etc. The main improvement point of the utility model is formed by the method that a bath body of the water bath is a metal block, the upper part of the metal block is provided with a cavity which is maintained with small gaps with an immersion object. The utility model is used for the constant temperature maintenance of some articles or temperature reference probes, and a temperature uniformity of the constant temperature water bath device can reach 0.05 DEG.
Description
The utility model relates to a kind of light water-storage heater that thermal source is arranged.
Conventional thermostatical water bath is to be used for certain product or certain temperature reference probe are kept constant temperature, and its mode promptly is to get final product in the water bath that thermostatted water is housed in product or the probe immersion thermostatical water bath.For keeping the temperature unanimity of heat transfer medium water in the water bath, conventional agitating device is set in the water-bath cell body, therefore the volume of water-bath cell body is relatively large, because the heat capacity ratio of heat transfer medium water is bigger, heat transfer rate is slow, so the uniformity of water bath each point temperature is difficult to accomplish that temperature control precision is undesirable less than 0.1 ℃ of degree, just do not satisfy instructions for use at some occasion bain-marie, and bain-marie when working noise bigger.
The purpose of this utility model is to provide a kind of at above-mentioned shortcoming can eliminate the thermostatical water bath that noise improves temperature control precision.
The purpose of this utility model is to realize like this, being about to the existing thermostatical water bath that includes devices such as heat power supply device, water bath improves, cancel original agitating device, reduce the volume of thermostatted water, increase the thick very fast metal derby of a kind of heat transfer rate that becomes of water bath body wall, be provided with on metal derby and immerse the thing shape and keep closely spaced cavity as water bath, this moment as the consumption of the water of heat transfer medium just seldom, it is many that essence is that thermal resistance that heat passes reduces, and purpose just can reach.
Thermostatical water bath after the improvement, each point temperature uniformities such as the point for measuring temperature of its water bath, hot spot and temperature-sensitive sensing point can reach 0.05 ℃ of degree, have improved the thermostatic control precision of whole water bath with thermostatic control.
Give to describe in detail below in conjunction with accompanying drawing.
Fig. 1 is the thermostatical water bath structural representation, is that the A-A of Fig. 2 analyses and observe.
Fig. 2 is the vertical view of Fig. 1.
A kind of heat power supply device that includes, the thermostatical water bath of water bath etc., the cell body of water bath are a kind of metal derby (1), and its material can be done with copper or aluminum, be provided with thereon and immerse the thing shape and keep closely spaced cavity (2), cavity (3), pour into suitable quantity of water in the cavity.Cavity (2) is set up in the middle of metal derby, is used to the thermometer of planting, and the immersion thing in the cavity (3) can be certain article that needs to keep constant temperature.As constant temperature benchmark probe etc.Cavity (3) can be a plurality of, decide as required, cavity (2), (3) root are provided with the connected chamber (6) of void space, to keep thermostatted water interface unanimity, the concrete size in little gap that immerses between thing and cavity can be according to the temperature uniformity of point for measuring temperature and hot spot, that is to say the requirement design of the temperature uniformity between each cavity and decide, so as long as the energy satisfied temperature uniformity be 0.05 ℃ spend or any little gap size of the more required precision of lean all can, metal derby profile Keyuan Garden shape or square etc.Heat power supply device can be with devices such as combustion gas heating or infrared electrical heating, mode of heating can or contain heating with lower heating, comprise a kind of in the utility model heat power supply device evenly around the heating wire coil (4) that is connected with radiator valve of metal derby (1) appearance, the parallel lumen centerline of its centerline average also can be designed to coil centerline as needs and intersect with lumen centerline.Keep constant temperature more effective for making, thus the heat-insulation layer (5) of routine put at heating wire coil peripheral hardware, and with shell (7) hard-pressed bale.With with thermostatical water bath the same manner of routine, temperature-sensitive sensor probe (8) is set in metal derby a part control in the device so that insert conventional constant temperature.As of the heating of this water bath as temperature reference probe, its appearance and size can make small volume and less weight.
Claims (3)
1. thermostatical water bath that comprises heat power supply device, water bath, the cell body that it is characterized in that water bath is a metal derby, is provided with thereon and immerses the thing shape and keep closely spaced cavity.
2. by the described thermostatical water bath of claim 1, it is characterized in that the root of cavity (2), cavity (3) is provided with the connected chamber (6) of void space.
3. by claim 1 or 2 described thermostatical water baths, it is characterized in that comprising in the heat power supply device a kind of evenly around the heating wire coil (4) that is connected with radiator valve of metal derby (1) appearance.
