Abstract

A thermal control system includes an enclosure configured to contain a thermal mass. A baffle plate is disposed in the enclosure. A heat exchanger is coextensive with and cooperates with the baffle plate to divide the enclosure into a first chamber and a second chamber. An air circulation element cooperates with the baffle plate and the heat exchanger to define an air circulation path and to cause air to flow through the air circulation path. The heat exchanger exchanges thermal energy with the air flowing through the air circulation path.
