  • Patent number: 11407271
    Abstract: An air-conditioning unit for a vehicle includes an air conditioning case, a blower, and a rectifying mechanism. The blower has a blower fan rotating around a fan axis and arranged in an in-case passage of the air conditioning case, and blows out air drawn from one side in an axial direction of the fan axis by rotation of the blower fan. The rectifying mechanism is arranged downstream of the blower fan in the in-case passage, and the air passes through the rectifying mechanism. The blower fan is arranged so that the other side of the fan axis that is opposite to the one side extends toward a downstream side of the in-case passage. The rectifying mechanism suppresses a swirling flow generated by the rotation of the blower fan in the air blown out from the blower fan as compared with the blown-out air prior to flowing into the rectifying mechanism.

  • Patent number: 11274670
    Abstract: A blower includes a centrifugal fan and a partition wall disposed in a suction space in the centrifugal fan. The partition wall has a base portion extending along a fan central axis to partition the suction space into a first space for a first fluid and a second space for a second fluid. The partition wall has an enlarged portion connected to an end of the base portion on another side of the fan central axis. The enlarged portion covers a part of a fan boss. A clearance passage is defined between the enlarged portion and the fan boss and has a first space side opening and a second space side opening. The enlarged portion is biased in the suction space to the second space such that a pressure at the second space side opening is less than a pressure at the first space side opening.

  • Publication number: 20210276397
    Abstract: An air-conditioning unit includes: an air-conditioning case in which an in-case passage is formed; and a blower having a blower fan arranged in the in-case passage to rotate around a fan axis so as to blow out air sucked from one side in an axial direction. A rectifying mechanism is arranged downstream of the blower fan in a flow of air in the in-case passage to define a rectifying passage to rectify a swirling flow generated by the rotation of the blower fan relative to the air blown from the blower fan. The rectifying mechanism includes a contracting rectifying passage having an inlet into which the swirling flow flows and an outlet through which the rectified air flows out. A flow path area of the outlet is smaller than a flow path area of the inlet.
