THERMAL ISOLATION IN A FLUIDIC BLOCK OF AN ACTIVELY CONTROLLING THERMISTOR

A fluidic block has a thermally conductive body with a first end and a second end opposite the first end. The body has a cutout portion formed therein between the first and second ends. The cutout portion partitions the body into a first region, a second region, and a thin region between the first and second regions. The cutout portion produces a thermal break between the first and second regions.The thermal break operates to guide a heat flow between the first and second regions through the thin region. A thermally conductive chromatography tube extends through the first, second, and thin regions from the first end to the second end of the body. The tube is in thermal communication with the body. A section of the tube may run in a transverse direction across the body in the thin region of the body. 本发明提供了种流体块，所述流体块具有导热主体，所述导热主体具有第端部和与所述第端部相反的第二端部。所述主体具有切口部分，所述切口部分在所述主体内于所述第端部与所述第二端部之间形成。所述切口部分将所述主体划分成第区域、第二区域和位于所述第区域与所述第二区域之间的薄区域。所述切口部分在所述第区域与所述第二区域之间产生断热区。所述断热区用于引导所述第区域与所述第二区域之间的热流通过所述薄区域。导热色谱管从所述主体的所述第端部穿过
