摘要： Disclosed is a flow path switching device including: a case including a first nozzle into which fluid is introduced, a second nozzle through which fluid is discharged, a plurality of inner outflow pipes through which fluid supplied from the first nozzle flows, a plurality of inner inflow pipes through which the fluid supplied to the second nozzle flows, and a flow path connection portion in which a space is formed to communicate the plurality of inner outflow pipes with the first nozzle or to communicate the plurality of inner inflow pipes with the second nozzle; a valve rotatably disposed in the space of the flow path connection portion, and having a first chamber connecting one of the plurality of inner inflow pipes and the first nozzle according to placement, and a second chamber connecting one of the plurality of inner outflow pipes and the second nozzle; and a motor disposed in one side of the valve and rotating the valve. Each of the first nozzle, the inner outflow pipe, and the flow path connection portion forms a flow path perpendicular to each other inside. A first chamber hole connecting the first chamber and a nozzle flow path formed inside the first nozzle is formed in the valve. A cross-sectional area of the nozzle flow path is reduced to a size corresponding to the first chamber hole from an inlet portion of the first nozzle towards the flow connection portion.

摘要： The present embodiment comprise: an inner housing having an inner space formed therein; a rotation shaft assembly supported in the inner housing and having a rotor and a bearing mounted on a rotation shaft thereof; a stator disposed to surround the rotor in the inner housing; an impeller connected to the rotation shaft; an outer housing surrounding the outer periphery of the inner housing and having an inlet body, formed thereat, for guiding air to the impeller. The present embodiment is advantageous in that a heat dissipation vane is provided on the outer peripheral surface of the inner housing to guide air which passes between the inner housing and the outer housing after being suctioned into the inlet body, and thus when being guided by the heat dissipation vane, the air having been moved by the impeller can efficiently absorb heat transferred from the stator to the heat dissipation vane and more stable flow than when colliding against the stator and the rotor, and thus can be quickly discharged.
