More Information
Summary:A temperature control device (2) comprises a number of active thermal sites (6) disposed at respective locations on a substrate (10), each comprising a heating element (13) for applying a variable amount of heat to a corresponding site of a medium and a thermal insulation layer (16) disposed between the heating element and the substrate. At least one passive thermal region (8) is disposed between the active thermal sites (6) on the substrate (10), each passive thermal region (8) comprising a thermal conduction layer (18) for conducting heat from a corresponding portion of the medium to the substrate (10). The thermal conduction layer (18) has a lower thermal resistance in a direction perpendicular to a plane of the substrate (10) than the thermal insulation layer (16). This enables precise control over both heating and cooling of individual sites in a flowing fluid, for example.
