The apparatus is designed to investigate and allow trainees to demonstrate the steady and unsteady heat conduction. the trainer has different samples to allow vary experiments and clear investigation for the steady and unsteady heat conduction.

                                     
  • The apparatus consists of a heater, heat sink, different samples and different temperature sensors.
  • Each sample is fitted with 12 temperature measurement points.
  • The temperature measurement points are designed to has as little influence on the temperature as possible and the core temperature of the sample is measured.
  • Each sample has a temperature sensor to measure the temperature at its center.
  • Samples are supplied in aluminum, steel, copper, brass and stainless steel to investigate the effect of the thermal conductivity.
  • The apparatus is equipped with the Transient-temperature/ heat flow chart.
  • The heat source consists of an electrically heated hot water circuit. An electronic controller ensures the heating water is kept at a constant temperature.
  • The heat sink is realized by means of a water-cooling system. An elevated tank ensures a constant cooling water flow rate.
  • The temperatures of the sample, heating and cooling water, as well as the electrical heating power and the cooling water flow rate are displayed digitally on the control panel.
  • The control panel provides the means to control the apparatus is addition to providing signal conditioning and display of measured parameters.
