PDE Modeling of a Microfluidic Thermal Process for Genetic Analysis Application

Figure 3

Cross-section view and dimensions of PCR LOC microchip. Due to the axisymmetric geometry of the chip, only half the chip is shown. The axis of symmetry is along the left vertical side. A circular hole is cut in the middle of the heatsink to provide thermal insulation under the heater and chamber. Heat is lost by free convection on the top and by conduction through the heatsink [21].
