Abstract
A reflow solder convection oven with at least one heater element and at least one blower assembly in fluid communication with the heater element. The blower assembly includes a mount structure including at least one intake port and at least two supply ports, a housing connected to the mount structure, a fan wheel, and a motor attached to the fan wheel. The housing has an interior surface defining at least two pressurization zones, and at least two outtake regions, each outtake region proximate a supply port of the mount structure. The periphery of the wheel is positioned in the housing to form dual pressurization zones, the housing defining at least two spline curves along the interior surface thereof, each curve having a starting node proximate a pressurization zone and a terminating node proximate an outtake region.
