Condensation device, flux recovery device, soldering device, water vapor removing method, flux recovery method and solder processing method

A water vapor removing method comprising the steps of:

• allowing a first cooling medium to pass through a first flow path between two or more inner tubes and an outer tube in an outer cooling unit including the two or more inner tubes and the outer tube located outside the two or more inner tubes,
• allowing, in interiors of the two or more inner tubes, condensation of water vapor contained in gas flowing through the interiors of the two or more inner tubes, to remove water vapor contained in the gas, and
• allowing the water that separated from flux and purified in a purification device to be supplied from the purification device to the condensation device as the first cooling medium,
• wherein the two or more inner tubes have a shape of a cylinder,
• 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,
• wherein the first cooling medium outlet is in fluid communication with the purification device without passing through a separation unit, and
• wherein the separation unit is configured to separate flux from the gaseous mixture by use of water, and discharges gas containing water vapor and water containing flux.

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 one or two or more inner tubes, an outer tube located outside the one or two or more inner tubes, and a first flow path through which a first cooling medium passes between the one or two or more inner tubes and the outer tube, and
• an inner cooling unit located inside the one or two or more inner tubes and including a second flow path through which a second cooling medium passes
• a purification device to which the water containing flux is supplied, and that separates flux from the water containing flux, and recovers flux, and
• 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 discharges 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.
