20130291563 | TWO-PHASE HEAT EXCHANGER MOUNTING - Embodiments of the present disclosure relate to controlling multiple Thermoelectric Coolers (TECs) to maintain a set point temperature of a chamber. In one embodiment, a controller receives temperature data corresponding to a temperature of the chamber. Based on the temperature data, the controller selectively controls two or more subsets of the TECs to maintain the temperature of the chamber at a desired set point temperature. In this manner, the controller is enabled to control the TECs such that the TECs operate to efficiently maintain the temperature of the chamber at the set point temperature. In another embodiment, the controller selects one or more control schemes enabled by the controller based on temperature data and a desired performance profile. The controller then independently controls one or more subsets of the TECs according to the selected control scheme(s). | 11-07-2013 |
