A blower unit for a vehicle and an air conditioning device including the same, the blower unit including: a scroll casing having an inlet port; a fan rotatably disposed in the scroll casing; a motor having a shaft coupled to the fan; and a bell mouth disposed in the inlet port, in which an inner end of the scroll casing, which defines the inlet port, is disposed to be spaced apart from the fan in a radial direction to define a separation space, and the bell mouth prevents air, which flows by a rotation of the fan, from flowing reversely through the separation space. The blower unit and the air conditioning device including the same prevent air from flowing reversely to the outside of the scroll casing by means of the arrangement of the bell mouth and the scroll casing and the structural shape of the bell mouth.

Blower unit for vehicle, and air conditioning device comprising same

Disclosed is an air conditioner for a vehicle, the air conditioner having an improved guide structure capable of increasing an air volume by preventing a collision between air flowing through an upper passage and air flowing through a lower passage. The air conditioner for a vehicle comprises: an air conditioning case having an air passage formed therein and an air outlet which includes a defrost vent and a face vent; and a heat exchanger for cooling and a heat exchanger for heating, which are provided in the air passage of the air conditioning case. The air conditioner for the vehicle further comprises: a temperature door arranged between the heat exchanger for cooling and the heat exchanger for heating in order to adjust the degree to which cold air, which has passed through the heat exchanger for cooling, is heated by the heat exchanger for heating; a cold air passage through which cold air that has passed through the heat exchanger for cooling bypasses the heat exchanger for heating; a warm air passage through which cold air that has passed through the heat exchanger for cooling passes through the heat exchanger for heating; a cold air guide unit for guiding the cold air downstream of the heat exchanger for cooling; and a warm air guide unit for guiding the warm air downstream of the heat exchanger for heating.

Air conditioner for vehicle

The invention relates to: a hybrid supported metallocene catalyst includes at least one first metallocene compound among the compounds represented by chemical formula 1, at least one second metallocene compound among the compounds represented by chemical formula 2 and a cocatalyst compound; a method for preparing an ethylene-&#x3b1;-olefin copolymer, comprising polymerizing olefin monomers in the presence thereof; and an ethylene-&#x3b1;-olefin copolymer having improved melt strength.
