Abstract
A device for determining the temperature conductivity, the heat capacity and/or the thermal conductivity of a material sample. The device has a light emitter for exposing a front side of the sample to a light energy beam and a radiation detector for determining the temperature rise at a rear side of the sample facing away from the front side by detecting the radiation emitted there as a function of temperature, and a sample holder for holding the sample in a defined position.
Claims13
A device for determining a temperature coefficient of conductivity, a heat capacity and/or a thermal conductivity of a material sample, comprising:
- a light emitter for exposing a front side of the sample to a light energy beam,
- a radiation detector for determining a temperature rise at a rear side of the sample facing away from the front side by detecting the radiation emitted there as a function of temperature, and
- a sample holder for holding the sample in a defined position, wherein a first aperture is arranged on the front side in front of the sample holder, wherein the light energy beam passes through the first aperture before it strikes the front side of the sample, and wherein a second aperture is arranged on the rear side behind the sample holder,
- wherein the apertures are irises with blades which rotate together inwards or outwards by means of a mechanism to form a smaller or larger aperture opening between them.
A device for determining a thermal index of a material sample, comprising:
- a light emitter for exposing a front side of the sample to a light energy beam,
- a radiation detector for determining a temperature rise at a rear side of the sample facing away from the front side by detecting the radiation emitted there as a function of temperature, and
- a sample holder for holding the sample in a defined position, wherein a first aperture is arranged on the front side in front of the sample holder, wherein the light energy beam passes through the first structure before it strikes the front side of the sample, and wherein a second aperture is arranged on the rear side behind the sample holder,
- wherein the sample holder comprises several supports or pins which are displaceable in the radial direction.
