Abstract
In a gas-intake-port array structure, which enables any temperature fluctuation during conveying time of a printed circuit board, a semiconductor wafer or the like to be reduced and allows the printed circuit board and the like to be very uniformly heated or cooled, a nozzle pattern Pis arranged to be line symmetry with a nozzle pattern Pin one upper or lower divided section of a nozzle layout region of the nozzle coverrelative to a center portion that is orthogonal to a conveying direction, as shown in FIG.. In order for the arrangement patterns diagonally arranged in the nozzle layout region to become identical, the nozzle pattern Pis arranged to be line symmetry with the nozzle pattern Pin the other upper or lower divided section. Intake portsandeach having a predetermined opening width are arranged between two blowing nozzlesor more and across a first row thereof and plural other rows having different phases, in order to circulate the gas blown from the blowing nozzles. Widths of the intake portsandare set so that they are gradually become narrower with increasing distance from the center portion.
