[0037] 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 heater (14) located above the first sample; a measurement unit (7) which contacts the first sample (4) and the second sample (5); and a cooler (8) located below the first sample (4) and the second sample (5). Thanks to the piston (6), the first sample (4) and the second sample (5) continuously contact each other. Therefore, it is provided that the measurement unit (7) is able to measure thermal contact resistances of the first sample (4) and the second sample (5). By performing the measurement process in the vacuum chamber (3), external environment factors do not affect the measurement results. Thus, more accurate measurement results are provided.

[0038] The measurement mechanism (1), which is the subject matter of the present invention, comprises a piston (6) which provides transmitting the pressure directly onto the first sample (4) and the second sample (5) due to a connection element (10) that comprises thereon a plurality of air ducts (9). Thanks to the connection element (10), the piston (6) is centred on the vacuum chamber (3) and provides power transmission. Due to the air ducts, force of the piston (6) proceeds through the connection element (10) without decreasing.

[0039] In an embodiment of the invention, the measurement mechanism (1) comprises a connection element (10) which has a conical form. Thus, aerodynamics of the piston (6) is provided. Material to be used is reduced, thereby providing ease-of-production.

[0040] In an embodiment of the invention, the measurement mechanism (1) comprises a connection element (10) comprising a central circle (11) through which the piston (6) passes, a circumscribing circle (12) which encircles the central circle (11), and air ducts which are located between the central circle (11) and the circumscribing circle (12). The air ducts are located between the central circle (11) and the circumscribing circle (12). The central circle (11) and the circumscribing circle (12) provide increasing the endurance of the connection element (10).

[0041] In an embodiment of the invention, the measurement mechanism (1) comprises a connection element (10) comprising support walls which are located between the air ducts. Thanks to the support walls, it is provided that endurance of the connection element (10) is increased. The connection element (10) makes high piston (6) powers balanced, thereby providing the piston (6) to be centred.

[0042] In an embodiment of the invention, the measurement mechanism (1) comprises support walls comprising a slope from the central circle (11) towards the circumscribing circle (12). Due to the fact that the support walls comprise slope, pressure transmitted by the piston (6) through the connection element (10) proceeds by sliding along the support walls. Therefore, movement of the piston (6) is facilitated.

[0043] In an embodiment of the invention, the measurement mechanism (1) comprises a plurality of connection points (13) which are located on the circumscribing circle (12) and provide fixing the connection element (10) onto the vacuum chamber (3). The connection element (10) is fixed onto the vacuum chamber (3) by means of the connection points. The connection points may be removable or irremovable connections.

[0044] In an embodiment of the invention, the measurement mechanism (1) comprises a connection element (10) which is made of a stainless steel material. Thus, mechanical strength of the connection element (10) is increased. An increase in the quality perception of the user is provided.

[0045] In an embodiment of the invention, the measurement mechanism (1) comprises a barometer (15) which is located on the piston (6) and provides measuring a pressure applied by the piston (6). Therefore, the pressure applied by the piston (6) onto the samples is able to be measured, and a more accurate measurement result is obtained.

[0046] With the present invention, there is achieved a measurement mechanism (1) having a connection element (10) which provides centring the piston (6) by balancing the power transmitted onto the vacuum chamber (3). Therefore, it is provided that the power transmitted by the piston (6) is transmitted directly onto the samples. The efficiency is increased.
