Abstract

The utility model discloses an instrument for measuring heat-conducting property of a thin material. The instrument is divided into two chambers, namely, a heating chamber (4-1) and a measuring chamber (4-2), wherein a target (3) is placed between the two chambers, after heat transferred from the heating chamber (4-1) penetrates through the target (3), a temperature sensor (5-2) mounted in the measuring chamber (4-2) measures the heat transfer conditions so as to obtain the heat conduction conditions of the target (3). The instrument is simple in structure and convenient to operate, can measure the heat conduction conditions of sheet, such as plastics, metal and inorganic non-metal materials, and provides basic experimental data for scientific research.

Description

For measuring the instrument of thin material heat conductivility

Technical field

The utility model relates to a kind of measuring instrument, is specifically related to a kind of instrument of measuring thin material heat conductivility, belongs to field of measuring technique.

Background technology

In the process that photovoltaic module is used out of doors, because inner solar battery sheet is when becoming electric energy by light energy conversion, self is also consuming part energy, these energy pass to material around by the form with heat, if the material for packaged battery sheet does not have good heat-conducting effect, heat cannot pass from cell piece surface fast, the temperature of so whole assembly will rise, temperature is higher, the photoelectric transformation efficiency of cell piece will be lower, produce negative temperature benefit, this power stage that not only affects assembly also can acceleration component aging, shorten the serviceable life of assembly.Material for the protection of cell piece is mainly EVA hot melt film and notacoria; notacoria is the polymer composites that assembly directly contacts atmosphere; play the effect of important transferring heat; if the heat conductivility of notacoria is bad; the heat radiation of whole assembly will be affected, so the heat conductivility of notacoria evaluates by being the important parameter whether notacoria is suitable for doing component package material.At present, on market, there is no and be directly used in the instrument that notacoria material thermal conductivity can be tested.

Summary of the invention

The problem existing for above-mentioned prior art, the utility model provides a kind of surveying instrument, and this instrument can test out the relative capacity of heat transmission of thin material, for assembly material test provides detection method easily.

To achieve these goals, the technical scheme that the utility model adopts is: for measuring the instrument of thin material heat conductivility, comprise heating chamber, measuring chamber, instrument lid, is separated by measured object in the middle of described heating chamber and measuring chamber, the inner heating chamber temperature sensor of installing of described heating chamber, described measuring chamber inside installs and measures room temperature sensor, and described temperature sensor connects signal feedback system, and described heating chamber adopts U-shaped heating tube heating.

Further, described heating chamber temperature sensor and measuring chamber temperature sensor respectively have two, are arranged on respectively the upper and lower of two Room.

The beneficial effects of the utility model are: measured object separates heating chamber and measuring chamber, heat can only pass from thin material, by Sensor monitoring to the temperature difference of two Room weigh the capacity of heat transmission of measured object, the utility model is simple to operate, practical and convenient, can fast detecting go out the relative capacity of heat transmission of different materials, and then optimize the material that is suitable for doing assembly notacoria.
