Embodiment Construction
[0034] A temperature control device for controlling temperature at multiple locations of a medium, comprising several active thermal locations arranged at various locations on a substrate, and each active thermal location includes a heating element and a heat insulating layer, the heating element is used for For applying a variable amount of heat to corresponding portions of the medium, an insulating layer is disposed between the heating element and the substrate. One or more passive thermal regions are disposed between active thermal sites on the substrate, and each passive thermal region includes a thermally conductive layer for conducting heat from a corresponding portion of the media to the substrate. The thermally conductive layer in the passive cooling area has a lower thermal resistance in the direction perpendicular to the plane of the substrate than the insulating layer in the active thermal area. In use, the substrate can act as a heat sink (either by exposing the su...

The temperature control device 2 includes several active thermal locations 6 arranged at various positions on the substrate 10, and each active thermal location includes a heating element 13 and an insulating layer 16, the heating element 13 is used to apply a variable amount of heat to The corresponding part of the medium, and the heat insulating layer 16 is arranged 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 thermally conductive layer 18 for conducting heat from a corresponding portion of the medium to the substrate 10 . The thermal resistance of the heat conducting layer 18 in a direction perpendicular to the plane of the substrate 10 is smaller than that of the heat insulating layer 16 . This enables, for example, precise control over both heating and cooling of various locations in the flowing fluid.
Description
technical field [0001] This technology relates to the field of temperature control, and more particularly, to controlling the temperature at various locations of a medium. Background technique [0002] Controlling the thermal pattern applied at different locations in a medium (such as a fluid or solid) is useful for some applications, for example to control chemical reactions at various locations such as . To be able to set different temperatures at different locations, or to change the temperature at a given location over time, some locations may need to be heated while other locations may need to be cooled. However, it is challenging to provide devices that allow rapid bi-directional control of temperature at different locations, while supporting the temperature range required for some applications. Contents of the invention [0003] At least some examples provide a temperature control device for controlling temperature at multiple locations of a medium, including: ...
