Abstract
A thermal cycling module includes an array of thermoelectric devices �36! divided into multiple zones �A, B, C, D! independently controlled by corresponding variable power supplies �56, 58, 60, 62!. The thermoelectric devices �36! provide localized, precise, and rapid control of both heating and cooling, while fluid from one of several fluid supplies �64, 66, 68! provides bulk heating or cooling via a fluid heat exchanger �38!. Sensors �46, 48, 50, 52! provide feedback of temperature or other process parameters to a controller �54! which generates control signals for controlling the power supplies �56, 58, 60, 62!, the fluid supplies �64, 66, 68!, and fluid valves �70, 72! which control fluid flow through the heat exchanger �38!.
