Embodiment
In order to make those skilled in the art understand better technical scheme of the present invention, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, it should be noted that, in the situation that not conflicting, the application's embodiment and the feature in embodiment can combine mutually.
Core of the present invention is to provide a kind of terminal bud area heating installation, and it is applicable to the experiment of terminal bud temperature control.
As depicted in figs. 1 and 2, terminal bud area heating installation of the present invention, comprises muff 1, adjustable digital display temperature controller 2.Described heat-preservation cylinder internal diameter is 15mm, and wall thickness is 10mm, and one end can be sealing.The material of muff 1 can be the foamed material with insulation effect, and foamed material has thermal insulation function, can guarantee that in muff, temperature is not affected by external environment as far as possible.In muff 1, be provided with electrothermal piece 3 and temp probe 5, the rated voltage of described electrothermal piece 3 is 5V, and resistance is 3-7 Ω.Described electrothermal piece is connected to adjustable digital display temperature controller 2 by USB connecting line, power supply adaptor 4, and power supply adaptor can be the required operating voltage of 5V electrothermal piece by 220V voltage transition.Described temp probe 2 is watertight transducer, can detected temperatures scope between 0-80 ℃.Temp probe 5 is connected to adjustable digital display temperature controller 2 by holding wire 6, the temperature that temp probe 5 detects in muff 1, and temperature signal is transferred to adjustable digital display temperature controller 2.Described adjustable digital display temperature controller 2 is controlled the size of current of electrothermal piece 3 according to the temperature signal of temp probe 5, adjustable digital display temperature controller can arrange a certain specified temp or temperature range as required, and can automatically open or close electrothermal piece power supply, accurately to control temperature within the specific limits.
As shown in Figure 2, described electrothermal piece 3 is electric heating sheets, and electric heating sheets is rolled into tubular, is arranged in muff 1.Electric heating sheets can be by multi-disc parallel connection or series connection, and when in parallel, total effective voltage is identical, need guarantee that single effective voltage is more than 4V during series connection, and the electric current of monolithic is not less than 500mA.In addition, described electrothermal piece 3 also can be resistance wire, and resistance wire spirality is arranged in muff 1.
Operation principle of the present invention: muff is enclosed within on terminal bud of plant, according to experiment needs, at adjustable digital display temperature controller, required a certain specified temp or temperature range (higher than room temperature) is set.Now, when in heating jacket, temperature is lower than set temperature, temp probe can feed back to temperature controller by the temperature signal of experiencing, and temperature controller will be connected connection power supply adaptor in the above.After the power connection of adapter, electric heating piece is started working, and jacket temperature raises.When temperature reaches set temperature, temp probe can be passed signal back temperature controller again, will the cut off the electricity supply power supply of adapter of temperature controller.This device can maintain experiment material metastable temperature range within the scope of certain space, guarantees completing smoothly of Heating Experiment.
