A MEASURING DEVICE

Abstract

A measuring device for measuring thermal contact resistance is disclosed. The device includes a body, a vacuum chamberon the body in which a thermal contact resistance measurement is conducted, a first sampleand a second sample which are placed in the chamberand are in contact with each other in such a way that heat transfer occurs, a pistonwhich ensures a continuous contact to take place between the first sampleand the second sampleduring a measurement, a cooler which is located under the first sampleand the second sample, at least one damperwhich is attached to the chamber, is located under the cooler, and enables to dampen the force applied by the pistonto provide a continuous contact between the first sampleand a second sample, an insulatordisposed between the coolerand the damper, providing insulation for the heat transfer conducted by the cooler.

Description

Claims

1. A measuring device (1) comprising a body (2),a vacuum chamber (3) in the body (2) in which a thermal contact resistance measurement is conducted,a first sample (4) and a second sample (5) which are placed in the chamber (3) and are in contact with each other in such a way that heat transfer occurs,a piston (6) which ensures a continuous contact to take place between the first sample (4) and the second sample (5) during a measurement,a cooler (7) which is located under the first sample (4) and the second sample (5),at least one damper (8) which is attached to the chamber (3), is located under the cooler (7), and enables to dampen the force applied by the piston (6) to provide a continuous contact between the first sample (4) and a second sample (5),an insulator (9) disposed between the cooler (7) and the damper (8), providing insulation for the heat transfer conducted by the cooler (7), wherein: at least one plate (10) is placed between the damper (8) and the insulator (9) to prevent deformation on the insulator (9) by homogeneously distributing the force exerted by the damper (8) on the insulator (9),at least one gap (11) is provided on the insulator (9) and of which the location is determined by a user, andone of the at least one plates (10) is placed in the gap (11) to homogeneously distribute the force exerted by the damper (8) on the insulator (9).

2. A measuring device (1) according to claim 1, comprising more than one damper (8), more than one plate (10) and more than one gap (11) disposed at equal distances to each other to homogeneously distribute the force exerted by the damper (8) to the insulator (9) when the force applied by the piston (6) is dampened.

3. A measuring device (1) according to claim 1, comprising more than one damper (8), more than one plate (10) and more than one gap (11) disposed at different distances to each other.

4. A measuring device (1) according to claim 1, comprising at least one sheet (12) placed between the cooler (7) and the insulator (9) for preventing any deformation from occurring on the insulator (9) when the force applied by the piston (6) is dampened.

5. A measuring device (1) according to claim 4, wherein the sheet (12) is disposed in a user-designated gap (11) on the insulator (9) to prevent deformation by homogeneously distributing the force exerted by the cooler (7) on the insulator (9).

6. A measuring device (1) according to claim 1, wherein the insulator (9) is produced from Teflon.

7. A measuring device (1) according to claim 1, wherein at least one of the at least one plate (10) is made of stainless steel.

8. A measuring device (1) according to claim 4, wherein each sheet (12) is made of stainless steel.
