Temperature conditioning unit, temperature conditioning system, and vehicle provided with temperature conditioning unit

A temperature conditioning unit, comprising:

• an impeller including:
• an impeller disk including:
• a rotary shaft at a center portion of the impeller disk;
• and
• a surface extending in a direction intersecting the rotary shaft;
• and
• a plurality of rotor blades extending in a direction along the rotary shaft, each of the rotor blades having a cross-sectional circular-arc shape in the direction intersecting the rotary shaft, the shape being a convex form curving toward a direction of rotation of the impeller disk, each of the rotor blades including:
• an inner-periphery-side edge located on the-rotary-shaft side;
• and
• an outer-periphery-side edge located on an opposite rotary-shaft side;
• an electric motor including
• a shaft for transferring a rotary motion to the rotary shaft;
• a fan case covering the impeller and including:
• a side wall disposed along the rotary shaft;
• a suction hole located in a direction of a shaft center of the rotary shaft;
• a discharge hole located in the direction along the rotary shaft, on an opposite side of the suction hole with respect to the side wall;
• and
• a flow path for conducting air along the side wall to the discharge hole when the impeller is rotated by the rotary motion transferred from the motor, the air having been suctioned from the suction hole and passed from the inner-periphery-side edge through the outer-periphery-side edge to the flow path;
• and
• a housing including
• an external surface on which the fan case is mounted, the housing accommodating a member to be temperature-conditioned in an inside of the housing,
• wherein the housing further includes an exhaust hole for exhausting the air to an outside of the housing, the air having been introduced into the housing, and
• the exhaust hole faces the suction hole of the fan case.
