Abstract
The utility model discloses a thermocouple thermoelectric coefficient tester capable of fast cooling, which comprises a ceramic cylinder, a baffle, heat dissipation holes and a fan, wherein the side wall of the ceramic cylinder is wound with multiple turns of a heating wire, and the ceramic cylinder is fixedly connected with a tester shell through two first fixing brackets; the baffle is a thin wafer and movably connected with the top part of the right end of the ceramic cylinder through a pin axle; the plurality of the heat dissipation holes are located at the right side surface of the tester shell; the fan is fixed on the tester shell through a second fixing bracket in such a manner that the fan is located at a position which is two centimeters away from the left side surface of the ceramic cylinder, and the horizontal center line of the fan overlaps with the horizontal center line of the ceramic cylinder; and the baffle is made of a high-temperature resistant plastic, and the diameter of the baffle equals to the outer diameter of the ceramic cylinder. The thermocouple thermoelectric coefficient tester capable of fast cooling has the beneficial effects that the thermocouple thermoelectric coefficient tester is simple, convenient and practical, and the experiment effect is obvious and safe.
Description
Technical field
The utility model belongs to the physical experiment apparatus field, but relates to a kind of thermopair thermoelectric coefficient analyzer of fast cooling.
Background technology
Thermopair thermoelectric coefficient mensuration is an important experimental project in the Experiment of College Physics, the temperature difference of thermopair is to control by thermopair thermoelectric coefficient analyzer, after the temperature end of thermopair, temperature sensor all are soldered on the circuit board, be fixed on again in the ceramic cylinder that is wound with heating wire in the sidewall, heating wire work, the ceramic cylinder temperature raises, and the temperature end temperature of thermopair increases.Because the ceramic cylinder heat radiation is slow, in case be heated to higher temperature, need could lower temperature for a long time, after the student has surveyed high-temperature data, think to go again to survey the data of certain lower temperature, often need very long wait, waste experimenter's plenty of time.
Summary of the invention
In order to solve the problem of existence, but the purpose of this utility model provides a kind of thermopair thermoelectric coefficient analyzer of fast cooling, for the experimenter brings convenience.
The technical scheme that its technical matters that solves the utility model adopts is: but the thermopair thermoelectric coefficient analyzer of fast cooling, comprise ceramic cylinder, baffle plate, louvre and fan, be wound with the multi-turn heating wire in the described ceramic cylinder sidewall, ceramic cylinder is fixedly connected with Instrument shell by two the first fixed mounts, described baffle plate is thin discs, be connected with ceramic cylinder right-hand member top movable by bearing pin, a plurality of described louvres are positioned at the right flank of Instrument shell, described fan is fixed on the Instrument shell by the second fixed mount and satisfies: fan is positioned at apart from about 2 centimetres of ceramic cylinder left surfaces to be located, its horizontal center line overlaps with the horizontal center line of ceramic cylinder, described baffle plate is made by high-temperature resistance plastice, and its diameter equals the external diameter of ceramic cylinder.
During use, the power supply of opening heating wire makes its work, and the ceramic cylinder temperature raises, and the thermopair temperature end temperature that is fixed on the circuit board increases, and baffle plate is vertical because of Action of Gravity Field, is pasting the ceramic cylinder right flank, stops hot-air convection in the ceramic cylinder; When the needs fast cooling, disconnect the power supply of heating wire, make its stopped heating, open the power supply of fan, fan work wind that temperature is lower is to ceramic cylinder, and baffle plate turns right under the wind-force effect, and the hot-air in the ceramic cylinder just can flow out to the right, by louvre heat is shed, reach the purpose of rapid cooling.
The beneficial effects of the utility model are, simple and convenient practicality, experiment effect obviously, safety.

Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing:
As shown in Figure 1, but the thermopair thermoelectric coefficient analyzer of the utility model fast cooling, comprise ceramic cylinder 7, baffle plate 3, louvre 2 and fan 8, be wound with multi-turn heating wire 1 in described ceramic cylinder 7 sidewalls, ceramic cylinder 7 is fixedly connected with Instrument shell 5 by two the first fixed mounts 6, described baffle plate 3 is thin discs, be connected with ceramic cylinder 7 right-hand member top movable by bearing pin 4, a plurality of described louvres 2 are positioned at the right flank of Instrument shell 5, described fan 8 is fixed on the Instrument shell 5 by the second fixed mount 9 and satisfies: fan 8 is positioned at apart from about 2 centimetres of ceramic cylinder 7 left surfaces to be located, its horizontal center line overlaps with the horizontal center line of ceramic cylinder 7, and described baffle plate 3 is made by high-temperature resistance plastice, and its diameter equals the external diameter of ceramic cylinder 7.
During use, the power supply of opening heating wire 1 makes its work, and ceramic cylinder 7 temperature raise, the thermopair temperature end temperature that is fixed on the circuit board 10 increases, baffle plate 3 is vertical because of Action of Gravity Field, is pasting ceramic cylinder 7 right flanks, stops ceramic cylinder 7 interior hot-air convections; When the needs fast cooling, disconnect the power supply of heating wire 1, make its stopped heating, open the power supply of fan 8, fan 8 is worked the wind that temperature is lower to ceramic cylinder 7, and baffle plate 3 turns right under the wind-force effect, and the hot-airs in the ceramic cylinder 7 just can flow out to the right, by louvre 2 heat is shed, reach the purpose of rapid cooling.
Claims (2)
