3.2. Thermal Properties
- A hot plate divided into a square element of 250 × 250 mm (the measuring zone), supplied with an assigned power rate, and a frame element with a total thickness of 125 mm (the guard zone), kept at the same temperature of the previous one by a closed-loop control system, in order to avoid lateral dispersion from measuring zone. The two parts are realized in aluminium with a thickness of 30 mm and internally heated by heating cartridges;
- A cold plate (500 × 500 mm) made of a parallelepiped, constituted by a tank with an internal spiral circuit where the chilled water flows;
- A second guarded hot plate to prevent a downward heat flux placed beneath the whole surface of the hot plate and kept at the same temperature.
