Row, quick, economic tester can the heat conductivility of substantially assessment material be just particularly important.
Utility model content
To solve the performance deficiency for the low heat conduction that prior art is present, the utility model provides one kind and passes through infrared thermal imaging
The instrument of test material heat conductivility.
In order to solve the above technical problems, technology of the present utility model uses following technical scheme：It is a kind of by infrared heat into
As the instrument of test material heat conductivility, including shell and power supply, the shell includes platform and lid, the platform interior bottom
Face is provided with support column, and the support column upper surface middle part is removably connected with hollowed part above thermal resistance, the platform and is placed with
Material sample to be assessed, the material sample lower surface middle part to be assessed by double faced adhesive tape and the adhesion of thermal resistance upper surface,
The lid is covered in the top of platform, and the cover inside is provided with dividing plate, and the dividing plate upper surface is provided with temperature sensor.
It is preferred that, the lid surface is provided with display screen and buzzer, and the display location is in the obliquely downward of buzzer.
It is preferred that, the power supply is electrically connected with by wire and the thermal resistance supported.
It is preferred that, the shell and support column use insulation material, and preferably thermal conductivity factor is less than 0.1W/mk insulation
Material.
It is preferred that, the power supply can use constant voltage source, constant-current supply or constant-power power source.
Beneficial effect：1st, the utility model provides electric energy by power supply for thermal resistance, it is ensured that thermal resistance power invariability, really
Thermal resistance heat production is consistent when protecting repeated detection, improves the accuracy of testing result.
2nd, the utility model, can be according to two when detecting testing sample by setting temperature sensor on lid dividing plate
The size of secondary temperature sensor data measured carrys out resolved materials heat conductivility difference, and it is higher that temperature sensor measures temperature, explanation
Thermal conductivity is better, while when temperature is too high, the buzzer on lid can alarm, reminds operating personnel's circuit short-circuit, carries
The high security of detection process.
3rd, the utility model is shot by thermal infrared imager to the material sample to be assessed after temperature stabilization, by than
The distribution situation of temperature can quickly find out the difference of thermal conductivity of material in more infrared figure, and the temperature of screen display is shown in contrast
Degrees of data, further increases the accuracy of result, while simple to operate.
