VAPOR PHASE SOLDERING DEVICE

PURPOSE:To improve a liquid recovery rate by the cooling means at a work carry-in and carry-out port sides by reducing the heater consuming electric power at a vapor tank side by interposing a heat insulating material between the vapor tank and a work carry-in port, and between the vapor tank and a work carry-out port. CONSTITUTION:A vapor tank 11 and work carry-in port 15 are formed by dividing with a separate member and an integrally formed flange 33 is fitted to a carry-in port 15 via the heat insulating material 32 formed in a square shape on the peripheral edge of the one side opening 31 of the vapor tank 11. Similarly, the vapor tank 11 and work carry-out port as well are formed by dividing with a separate member and an integrally formed flange is fitted to a carry-out port 16 via the heat insulating material 35 formed in a square shape on the peripheral edge of the opening 34 at the other side of the vapor tank 11. By the heat insulating materials 32, 35 the heat transfer to the carry-in and carry-out ports 15, 16 of the heat generated by the heater 14 of the vapor tank 11 is prevented and the heat of the heater 14 is effectively utilized in the formation of a saturated vapor phase 13 inside the vapor tank 11. And due to the heat transfer from the vapor tank 11 being shielded the internal temp. is maintained at low temp. with good efficiency by a cooling means 17 and the recovery rate of the condensed liquid is improved.
