Heat distribution in differential scanning calorimeter furnace
The paper deals with the issues of heat distribution in the DSC furnace with consideration of its basic operation modes and geometrical dimensions. The paper lists the results of experiments conducted for numerical determination of the influence of the radiation of the substrate on the process of heat transfer from the heater to the cells with the test substance through the effect of heat conduction. An equation of heat conduction of the substrate in the oven with consideration of change of the ratio of heat conduction of the air layer between the substrate and the oven cover with consideration of the influence of the thermal radiation of the substrate at high temperature operation modes. The resulting equation is fundamental for mathematical description of the object of the automatic substrate temperature control which allows to provide the best indices of heating quality of the test substance.
