<p><P>PROBLEM TO BE SOLVED: To provide a reflow soldering device in which a plurality of blowers for circulating gas in a furnace are provided in parallel in the axial direction, the blowers have a structure of sucking from the axial direction and discharging from the outer circumferential face, and, the guide passage for discharge connecting to the discharge port of each blower are adjacent via partition walls, in which the vibration of the partition walls by the discharge wind of the blowers is prevented. <P>SOLUTION: A pair of blowers 9A, 9B for circulating gas in a furnace 1 are arranged in an axial direction, the blowers 9A, 9B have a structure of sucking from the axial direction and discharging from the outer circumference, and, in the ducts 13A, 13B for discharge respectively connected to the discharge ports of the blowers 9A, 9B, the parts in the vicinity of the discharge ports of the blowers 9A, 9B are adjacent to each other via a partition 23. The device further includes an air direction changing plate 30 changing the air direction of the gas discharged from the blowers to a direction far from the partition wall 23. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
