一般說明

The Computer Controlled Heat Conduction Unit, "TCCC", consists of two modules electrically heated.

One of the modules is provided of a cylindrical metal bar for the realization of a series of experiments of linear heat conduction. While the ther one consists of a metallic disk that allows studying the radial heat conduction. Both modules are provided with a series of takings for the connection of a series of temperature sensors "T" type (high precision). To maintain the gradient of constant temperature, on a side of the modules, a cooling system has been inserted by circulating water.

The instrumentation provided with the unit allows making the measuring of the temperature and the electric power given to the heating element. For the control of the given energy it has a control circuit that allows the variation from 0 to 100 % of the maximum heating element power, through the computer.

The linear heat conduction module is supplied with interchangeable samples of different materials, different diameters and different insulating materials that allow to demonstrate the area effects, the conductivity and the combinations in series in the heat transfer process.

The radial heat conduction module consists of a disk with a refrigeration system in its end. In this module, there are six temperature takings placed along its radius. The heating element is placed exactly in its central point surrounded by an effective insulating material.

The two modules incorporate a water regulation valve, which allows the flow of cooling water to be varied, a water flow sensor, and temperature sensors at the water inlet and outlet.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
