1. A flux recovery device that recovers flux from a gaseous mixture containing a flux component, the flux recovery device comprising:
a condensation device comprising:
an outer cooling unit including two or more inner tubes, an outer tube located outside the two or more inner tubes, and a first flow path through which a first cooling medium passes between the two or more inner tubes and the outer tube, wherein the two or more inner tubes have a shape of a cylinder
a purification device to which the water containing flux is supplied, and that separates flux from the water containing flux, and recovers flux
a piping that supplies water separated from flux and purified in the purification device from the purification device to the condensation device and
a separation unit that separates flux from the gaseous mixture by use of water, and discharges gas containing water vapor and water containing flux,
wherein the outer cooling unit includes a first cooling medium inlet, and a first cooling medium outlet,
wherein the first cooling medium is configured to be supplied from the first cooling medium inlet to the first flow path, and discharged from the first cooling medium outlet, and
wherein the first cooling medium outlet is in fluid communication with the purification device without passing through the separation unit.
