[0016] All the parts illustrated in figures are individually assigned a reference number and the corresponding terms of these numbers are listed below.

[0028] The measurement mechanism (1) comprises a body (2); a vacuum chamber (3) which is located on the body (2) and in which a measurement process is performed; a first sample (4) and a second sample (5) between which a heat transfer occurs, which are placed in the vacuum chamber (3) and contact each other; a piston (6) which provides the first sample (4) and the second sample (5) to continuously contact each other; a main heater (7) which is located above the first sample (4) and the second sample (5); and a cooler (8) which is located below the first sample (4) and the second sample (5). The piston (6) exerts a force to the first sample (4) and the second sample (5) during the measurement. Thus, the first sample (4) and the second sample (5) are in contact with each other during the measurement. A heat flow is generated from the main heater (7) towards the cooler (8) on the vacuum chamber (3). Thus, a heat transfer occurs between the first sample (4) and the second sample (5) due to the heat flow while they contact each other. Thus, thermal contact resistances thereof can be measured.

[0029] The measurement mechanism (1), which is the subject matter of the present invention, comprises at least one wall (9) located above the cooler (8) and at least partially surrounding the first sample (4) and the second sample (5). Thanks to the wall (9), there would be no heat loss around the first sample (4) and the second sample (5) during the measurement. Thus, measurement accuracy is improved.

[0030] In an embodiment of the invention, the measurement mechanism (1) comprises at least one heater (10) which is located on the wall (9) and provides preventing heat dissipation through the first sample (4) and the second sample (5). It is aimed to create a heat shield on the wall (9) by means of the heater (10). Therefore, heat losses are prevented.

[0031] In an embodiment of the invention, the measurement mechanism (1) comprises a heater (10) which is a heat tape (11). The heat tape (11) provides direct contact with the wall (9). Thus, it is provided that the heat is transmitted to the wall (9) without heat loss. The heat tape (11) is electrically operated.

[0032] In an embodiment of the invention, the measurement mechanism (1) comprises a wall (9) which is in thermal contact with the cooler (8). Thanks to the cooler (8), temperature at an end of the wall (9) which is in contact with the cooler (8) decreases and the wall (9) cools down.

[0033] In an embodiment of the invention, the measurement mechanism (1) comprises a heat tape (11) located at an end of the wall (9) which is not in contact with the cooler (8). Thus, while the wall (9) is heated by the heat tape (11) from one end, it is cooled by the cooler (8) from the other end. Thus, a heat flux is generated on the wall (9) from the heat tape (11) towards the cooler (8). Heat flux provided between the cooler (8) and the main heater (7) located at the measurement mechanism (1) is supported by the wall (9). Thus, the measurement is performed without heat loss through the first sample (4) and the second sample (5).

[0034] In an embodiment of the invention, the measurement mechanism (1) comprises a wall (9) which is made of a conductive material. Thus, it is facilitated to create a heat flux between the heat tape (11) and the cooler (8).

[0035] With the present invention, there is provided a measurement mechanism (1) which provides preventing thermal losses that may occur through the samples during the measurement. Thanks to a wall (9) surrounding the samples, heat losses to be occur through the samples are prevented.
