An Analysis of the Two-Dimensional Heat Transfer Model of the PCR Instrument Pedestal

摘要

By analyzing the heat transfer situation of the polymerase chain reaction (PCR) instrument pedestal, a mathematical model to reflect the temperature field function of the pedestal is proposed, and then this model is simplified to obtain a simple two-dimensional heat transfer model. According to the results of the simplified mathematical model, the temperature field of the PCR instrument pedestal is calculated and simulated. And according to the calculation of two-dimensional temperature field, the influence of various parameters the on the pedestal's temperature field is analyzed when the instrument is working in an uneven heating mode.
