摘要:
Provided is an air blower for an air conditioner. The air blower for the air conditioner includes a centrifugal fan and a fan housing. The fan housing covers the centrifugal fan, and forms a scroll-type flow path having a varying cross-sectional area and guiding air forcibly blown by the centrifugal fan to an outlet. Here, a bottom surface of the scroll-type flow path inclines and is thinnest near a region where the scroll-type flow path ends. The thickness of the bottom surface progressively increases along a straight line running from a region where the bottom surface is thinnest to an opposite outer side of the scroll-type flow path through a center of the centrifugal fan.

An outdoor fan for an air-conditioner is provided to reduce unnecessary energy consumption and noise generated during an operation by reducing a side circulation flow generated when the fan rotates. The outdoor fan may include a hub shaft with a side hole, and rotary blades that convert rotary power received from the hub shaft into a pressure difference. The hub shaft may include a main plate unit perpendicular to the hub shaft and, positioned at a front side as compared to a virtual plane that includes the side hole, and the main plate unit to cover at least a portion of the hub shaft.

An air conditioner is provided. A heat exchange unit of the air conditioner may include a blower fan that generates air flow within a housing, and a first shroud that guides the air flow generated by the blower fan to an outside of the cabinet. A second shroud may be coupled to an upstream end of the first shroud. An outer peripheral surface of a transverse section of the second shroud may be curved so as to stabilize air flow generated by the blower fan.

A method for manufacturing a semiconductor light emitting device package includes forming a light emitting structure including a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer sequentially stacked on a growth substrate, forming a reflective layer on a first surface of the light emitting structure corresponding to a surface of the second conductivity-type semiconductor layer, forming bumps on the first surface, the bumps being electrically connected to the first or second conductivity-type semiconductor layer and protruding from the reflective layer, bonding a support substrate to the bumps on the first surface, removing the growth substrate, bonding a light transmissive substrate coated with a wavelength conversion layer to a second surface of the light emitting structure from which the growth substrate is removed, and removing the support substrate. The reflective layer covers at least portions of side surfaces of the light emitting structure and the bumps.
