Description
Technical field
The utility model belongs to Physical Experiment equipment field, is specifically related to a kind of Physical Experiment and conducts comparator with heat.
Background technology
Heat conduction is extremely important in people's daily life, the eating of people, wear, live, there is close contacting the provisional capital with hot the conduction, so it is very important to understand the thermal conductivity of various materials.
In the physics teaching material, the thermal conductivity of various materials there is the data introduction, the thermal conductivity of the various materials of Data Comparison that students can provide by teaching material, but can not contrast by experiment intuitively the thermal conductivity of material.
The utility model content
Order of the present utility model ground is the problem that can not contrast by experiment intuitively the thermal conductivity of material in order to solve the student, provides a kind of Physical Experiment to conduct comparator with heat, and its technical scheme is as follows:
Physical Experiment is conducted comparator with heat, and it comprises stand, spirit lamp, contrast platform and probe-type electronic thermometer.Described stand comprises top board, pillar and base plate, the plate face of described top board is square, circular hole is arranged in the middle of the described top board, described pillar has four, following four jiaos of described top board are fixedly connected with the upper end of four pillars is vertical respectively, one side of described top board is fixedly connected with two annulus, and the lower end of described four pillars is fixedly connected with base plate is vertical.Described spirit lamp be placed on the base plate of described stand and be positioned at top board circular hole under.Described probe-type electron temperature is in respect of two, is inserted in respectively in two annulus of top board side of described stand.Described contrast platform is the square plate of fine silver material, is fixedly connected with above the top board of described contrast platform and described stand.
Preferably: the top board of described stand is copper material chrome-faced layer.
The beneficial effects of the utility model are: can heat two kinds of solid matters simultaneously, and utilize the probe-type electronic thermometer to observe the temperature changing process of two kinds of solid matters, the thermal conductivity of two kinds of materials is had intuitively contrast.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, Physical Experiment is conducted comparator with heat, and it comprises stand 1, spirit lamp 2, contrast platform 3 and probe-type electronic thermometer 4.Described stand 1 comprises top board 1-1, pillar 1-2 and base plate 1-3, the plate face of described top board 1-1 is square, circular hole 1-1-1 is arranged in the middle of the described top board 1-1, described top board 1-1 is copper material chrome-faced layer, described pillar 1-2 has four, following four jiaos of described top board 1-1 are fixedly connected with the upper end of four pillar 1-2 is vertical respectively, and the side of described top board 1-1 is fixedly connected with two annulus 1-1-2, and the lower end of described four pillar 1-2 is fixedly connected with base plate 1-3 is vertical.Described spirit lamp 2 be placed on described base plate 1-3 upper and be positioned at top board 1-1 circular hole 1-1-1 under.Described probe-type electronic thermometer 4 has two, and two probe-type electronic thermometers 4 are inserted in respectively among described two annulus 1-1-2.Described contrast platform 3 is square plates of fine silver material, described contrast platform 3 be fixedly connected with above the described top board 1-1.
Using method is: two kinds of solid matters that will contrast are first respectively made a cube, two cubical measure-alike, and stamp identical circular hole two cubical same positions, the probe diameter of the diameter of circular hole and probe-type electronic thermometer 4 is coincide, and then two cubes is placed on the described contrast platform 3.The probe of two described probe-type electronic thermometers 4 is inserted respectively in two cubical circular holes, light at last spirit lamp 2 heating contrast platforms 3, observe the temperature variation that two described probe-type electronic thermometers 4 show, contrast the thermal conductivity of two materials according to the difference of temperature variation.
The utility model principle: the temperature conductivity of fine silver is very high, so two kinds of materials that utilize the contrast platform 3 of fine silver material can be fast the heat transferred of spirit lamp 2 will be contrasted, but fine silver is easy to distortion, once distortion just can not well be fitted with the square that the material that will contrast is made, so the contrast platform 3 of fine silver is fixed on the top board 1-1, prevent from contrasting platform 3 distortion, top board 1-1 has reserved circular hole 1-1-1, and spirit lamp can directly heat contrast platform 3 by circular hole 1-1-1.
