<p>Disclosed is a heat exchange module for a vehicle which is capable of suppressing peeling, stall, or the like on the blade surface to overcome reduced aerodynamic performance, aggravated noise, or the like even under the operating condition of a large air volume and a high pressure loss when using a fan unit with one fan configuration in which motor input is below a predetermined level. Specifically disclosed is a heat exchange module for a vehicle in which a fan unit (4) is provided on the downstream side or a rectangular-shaped heat exchanger, and in which the fan unit (4) is provided with a shroud (5) having a bell mouth (9) and a ring opening section (10), a propeller fan (8) disposed in the ring opening section (10), and a fan motor for rotary-driving the propeller fan (8), wherein the fan unit (4) is a unit with one fan configuration in which motor input is below a predetermined level, and the propeller fan (8) has two pairs of sets of winglet (26, 27) erected on both the pressure surface and negative pressure surface on the root side of a blade (16) at predetermined intervals in the radial direction along the peripheral direction.</p> |
