Abstract

An object is to provide a vehicle heat-exchange module that is capable of reducing abnormal sound generated by interference between rotor blades of a propeller fan and high-static-pressure regions generated at leading edges of stator blades, while decreasing the input power of a fan motor by providing the stator blades on the downstream side of the propeller fan. In a vehicle heat-exchange module (1) including a fan motor (7) that drives a propeller fan (8), the fan motor (7) is supported to the fan shroud (5) at a downstream side of the propeller fan (8) via motor support struts (6) formed into stator blades in a radiating pattern, and a distance (L1) between stator blades (14) formed of the motor support struts (6) and rotor blades (9) of the propeller fan (8) for a narrowest portion at the same position in the radial direction is at least 0.018D < L1, where D is the diameter of the rotor blades (9).
