Thermal convection generating chip, thermal convection generating device, and thermal convection generating method

A thermal convection generating chip comprising:

• a substrate;
• at least one annular thermal convection pathway provided in the substrate, the annular thermal convection pathway having an inside circumferential surface and an outside circumferential surface;
• at least one liquid supply path that is provided in the substrate, that is connected to the outside circumferential surface of the annular thermal convection pathway, and through which a liquid is supplied into the annular thermal convection pathway;
• and
• at least one gas discharging path that is provided in the substrate, that is connected to the outside circumferential surface of the annular thermal convection pathway, and that is configured to receive gas in a liquid in the annular thermal convection pathway,
• wherein the thermal convection generating chip has a rotation axis and is configured to rotate to apply centrifugal force to a liquid in the annular thermal convection pathway,
• the liquid supply path and the gas discharging path are arranged in a symmetric manner with respect to the annular thermal convection pathway,
• the liquid supply path includes a first portion connected to the annular thermal convection pathway, a second portion connected to the first portion, and a third portion connected to the second portion, the second portion having a width larger than a width of the first portion, the third portion having a width smaller than the width of the second portion,
• the at least one annular thermal convection pathway includes a plurality of annular thermal convection pathways that are rotatable about the rotation axis, and
• the annular thermal convection pathways are arranged in a symmetric manner with respect to the rotation axis.
