Temperature conditioning unit, temperature conditioning system, and vehicle

A temperature conditioning unit including a first temperature conditioning unit part, a second temperature conditioning unit part, and a blower,

• the first temperature conditioning unit part including a first housing, a first air hole part, a first air chamber, a first object to be temperature-conditioned, and a second air chamber,
• the second temperature conditioning unit part including a second housing, a second object to be temperature-conditioned, a second air hole part, and a third air chamber,
• the temperature conditioning unit comprising:
• a partition wall formed such that a part of a wall of the first housing serves as a part of a wall of the second housing or a partition wall formed such that a part of the wall of the second housing serves as a part of the wall of the first housing;
• an air path for connecting an air intake hole of the blower and the second air chamber so as to allow passage of air;
• a structure for disposing an outlet hole of the blower in the third air chamber so as to allow passage of air;
• a structure for disposing a part of the second object to be temperature-conditioned inside the third air chamber;
• and
• a structure for disposing a part of the blower inside the third air chamber, wherein the blower includes
• an impeller disk that has a rotary shaft at a central portion and a surface extending in a direction intersecting the rotary shaft,
• an impeller that has a plurality of rotor blades, each of the rotor blades extending in a direction along the rotary shaft, having a circular-arc cross section in the direction intersecting the rotary shaft, and having an inner-periphery-side end positioned closer to the rotary shaft and an outer-periphery-side end positioned on an opposite side from the rotary shaft, the circular-arc cross section protruding in a direction of rotation of the impeller disk,
• an electric motor that includes a shaft and that transmits a rotary motion to the rotary shaft through the shaft,
• a fan case that has a side wall extending in a longitudinal direction of the rotary shaft so as to cover the impeller and the air intake hole positioned in the longitudinal direction of the rotary shaft, and
• an outlet hole corresponding to the air intake hole, and
• the fan case has a flow path for guiding, toward the outlet hole along the side wall, air that is suctioned through the air intake hole and flows toward the outer-periphery-side end from the inner-periphery-side end due to rotation of the impeller by the rotary motion transmitted from the electric motor.
