Abstract: Provided is an air conditioner. The air conditioner includes: a blower fan blowing air; a blower motor rotating the blower fan; and a blower housing coupled with the blower motor and including a ring-shaped air blowing flow passage in which air discharged from the blower fan flows. Here, the blower housing includes a plurality of vanes that are disposed spaced from each other in a circumferential direction on the air blowing flow passage over the blower fan.

Abstract: A turbine blade airfoil including various internal cavities that are fluidly coupled is disclosed. The airfoil may include a first pressure side cavity positioned adjacent a pressure side of the airfoil. The first pressure side cavity may receive a coolant. The airfoil may also include a second pressure side cavity positioned adjacent to and fluidly coupled to the first pressure side cavity, and at least one channel positioned between and fluidly coupling the first and second pressure side cavities. The channel may be positioned radially between a top surface and a bottom surface of the first and second pressure side cavities. Additionally, the airfoil may include a trailing edge cooling system positioned adjacent a trailing edge and in direct fluid communication with the first pressure side cavity. The trailing edge cooling system may receive a portion of the coolant from the first pressure side cavity.
