AXIAL FLOW FAN, BLOWING DEVICE, AND REFRIGERATION CYCLE DEVICE

An axial fan includes a hub, and a blade. The hub has a rotation axis, and is configured to be driven to rotate. The blade is connected to the hub, and has a front edge and a rear edge. The blade has a flow control portion. The flow control portion is located in at least part of a portion between the front edge and the rear edge, and guides a flow of a fluid on a pressure surface of the blade. The flow control portion has a regional inner edge, a regional outer edge, and a sectional portion. The regional inner edge is located closer to the inner circumference of the axial fan than is the regional outer edge. The regional outer edge is located closer to the outer circumference of the axial fan than is the regional inner edge. The sectional portion is a section that is located between the regional inner edge and the regional outer edge and is perpendicular to the rotation axis. The sectional portion is bent to have a concave part of the pressure surface. In the flow control portion, a virtual regional intermediate line, which extends through the middle of a region between the regional inner edge and the regional outer edge in the radial direction, is located closer to the outer circumference than is a virtual blade intermediate line, which extends through the middle of the blade in the radial direction. In the sectional portion, the distance to a portion of the pressure surface that is farthest in the normal direction from a sectional straight line that is a straight line connecting the regional inner edge and the regional outer edge is defined as a projection amount. The projection amount increases with increasing distance from the front edge toward the rear edge.
