A heater core 8 that warms the air cooled in the evaporator 6 by using coolant heated by heat dissipation of the engine, and is rotatably installed between the heater core 8 and the evaporator 6. It comprises a heater core damper (9) for blocking between the heater core 8 and the evaporator (6) when cooling.

그리고, 도 2에 도시된 바와 같이 상기 증발기(6)에서 기화된 냉매를 순환하여 사용할 수 있도록 엔진 측에 압축기(10)가 설치되어 엔진의 구동력을 이용하여 기화된 냉매를 고온, 고압으로 압축시키고, 엔진을 냉각수를 냉각시키는 라드에이터(미도시) 앞에 응축기(12)가 설치되어 차가운 외기를 이용하여 고온, 고압의 냉매를 응축시키며, 상기 응축기(12)와 증발기(6) 사이에 팽창밸브(14)가 설치되어응축된 냉매의 압력을 낮춘 후 상기 증발기(6)로 보낸다.And, as shown in FIG. 2, the compressor 10 is installed on the engine side to circulate and use the vaporized refrigerant in the evaporator 6 to compress the vaporized refrigerant to a high temperature, high pressure using the driving force of the engine In addition, a condenser 12 is installed in front of a radiator (not shown) for cooling the coolant of the engine to condense the refrigerant of high temperature and high pressure using cold outside air, and between the condenser 12 and the evaporator 6, an expansion valve ( 14) is installed to lower the pressure of the condensed refrigerant is sent to the evaporator (6).

여기서, 상기 에어 덕트(2)는 차실 내 또는 외부 공기를 공기조화시스템의 공조순서에 따라 안내하는 공조 덕트(2a)와, 상기 공조덕트(2a)의 출구부위에서 여러 갈래로 분기되고 차실의 여러곳에 형성된 벤트(미도시)와 각각 연결되어 공조된 공기를 차실로 안내하는 복수개의 벤트덕트(2b,2c,2d)로 이루어진다.Here, the air duct (2) is an air conditioning duct (2a) for guiding the air inside or outside the vehicle in accordance with the air conditioning order of the air conditioning system, and branched at the outlet of the air conditioning duct (2a) in several branches and several It is composed of a plurality of vent ducts (2b, 2c, 2d) connected to the vent (not shown) formed therein to guide the air conditioned to the vehicle compartment.

상기한 과제를 해결하기 위한 본 발명에 따른 차량용 공기조화시스템의 에어덕트는 공기가 공조될 수 있도록 공기를 공기조화시스템을 따라 안내하는 공조 덕트와; 상기 공조덕트에서 복수개로 분기되고 차실에 형성된 벤트와 각각 연결되어 상기 공조덕트에서 공조된 공기를 차실로 안내하는 벤트덕트와; 상기 벤트덕트와 공조덕트 사이에 설치되어 상기 벤트덕트로 유입되는 공기의 유동이 균일하도록 상기 공조덕트에서 벤트덕트로 유동되는 공기를 분산시키는 허니콤을 포함하여 구성된다.Air duct of the vehicle air conditioning system according to the present invention for solving the above problems is an air conditioning duct for guiding the air along the air conditioning system so that air can be air-conditioned; A vent duct branched into the plurality of air conditioning ducts and connected to vents respectively formed in the vehicle compartment to guide air air-conditioned from the air conditioning duct to the vehicle compartment; And a honeycomb disposed between the vent duct and the air conditioning duct to disperse the air flowing into the vent duct from the air conditioning duct so that the air flowing into the vent duct is uniform.

이하, 본 발명의 실시 예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

상기 본 발명에 따른 차량용 공기조화시스템의 에어 덕트는 도 3 및 도 4에 도시된 바와 같이 차실 내 또는 외부 공기를 공기조화시스템을 공조 순서따라 안내하여 공기조화가 이루어지도록 하는 공조덕트(50)와, 상기 공조덕트(50)의 출구부위(50a)에서 복수개로 분기되고 차실에 여러부위에 형성된 벤트(미도시)와 각각 연결되어 상기 공조덕트(50)에서 공조된 공기를 차실로 안내하는 벤트덕트(52)와, 상기 벤트덕트(52)와 공조덕트(50) 사이에 설치되어 상기 공조덕트(50)에서 벤트덕트(52)로 유입되는 공기의 유동이 균일하도록 공기의 유동을 곧은 방향으로 안내하는 유동균일화수단을 포함하여 구성된다.The air duct of the vehicle air conditioning system according to the present invention, as shown in Figures 3 and 4 and the air conditioning duct 50 to guide the air conditioning system to the air conditioning system in the interior or outside the air conditioning system A vent duct branched into a plurality of outlet portions 50a of the air conditioning duct 50 and connected to vents (not shown) formed in various parts of the vehicle compartment to guide the air conditioned in the air conditioning duct 50 to the vehicle compartment. And a 52 installed between the vent duct 52 and the air conditioning duct 50 to guide the flow of air in a straight direction so that the air flowing into the vent duct 52 from the air duct 50 is uniform. It comprises a flow homogenizing means to.

상기 공조덕트(50)는 입구부위(50b)에 설치된 송풍기(62)의 송풍력에 의해 차실 내 순환공기 또는 외부 공기를 선택적으로 유입받아 공조순서에 따라 안내하는데, 공기를 냉각시키는 증발기(64)와 공기를 따뜻하게 데우는 히터 코어(66)가 차체에 분산되어 설치되어 있고, 차체가 다른 장치들로 인해 복잡하기 때문에 여러개로 나누어짐과 아울러 설치 장소에 따라 다양한 형상으로 굴곡된다.The air conditioning duct 50 receives the circulating air or the outside air selectively in the cabin by the blowing force of the blower 62 installed at the inlet 50b, and guides the air duct 50 according to the air conditioning order. The evaporator 64 cools the air. Heater cores 66 for warming the air and air are distributed and installed in the vehicle body, and because the vehicle body is complicated by other devices, the heater core 66 is divided into several parts and bent in various shapes according to the installation place.

따라서, 상기 공조덕트(50)의 안내를 받는 공기 유동은 상기 공조덕트(50)의 형상에 따라 빈번하게 변화면서 상기 공조덕트(50)의 출구부위(50a)로 안내되기 때문에 상기 공조덕트(50)의 출구부위(50a)에서 상기 벤트덕트(52)의 입구부위(52a)로 유입되는 공기의 유동이 매우 불균일하다.Therefore, the air flow guided by the air conditioning duct 50 changes frequently depending on the shape of the air conditioning duct 50 and is thus guided to the outlet 50a of the air conditioning duct 50. The flow of air flowing into the inlet portion 52a of the vent duct 52 from the outlet portion 50a of) is very uneven.

상기 유동균일화수단은 상기 공조덕트(50)의 출구부위(50a)와 동일한 크기로 형성되어 상기 공조덕트(50)의 출구부위(50a)와 벤트 덕트(52)의 입구부위(52a) 사이를 구획하도록 상기 공조덕트(50)의 출구부위(50a)에 설치되고, 단면이 벌집모양의 격자구조를 갖는 허니컴 보드(56)로 구성된다.The flow homogenizing means is formed to have the same size as the outlet portion 50a of the air conditioning duct 50 to partition between the outlet portion 50a of the air conditioning duct 50 and the inlet portion 52a of the vent duct 52. The honeycomb board 56 is installed at the outlet 50a of the air conditioning duct 50 and has a honeycomb lattice structure in cross section.

특히, 상기 허니컴 보드(56)는 상기 공조덕트(50)에서 벤트덕트(52)로 유입되는 공기의 유동을 방해하지 않도록 각 벌집모양의 격자(56a)가 소정의 면적을 갖으며, 상기 공조덕트(50)에서 벤트덕트(52)로 유입되는 공기의 유동이 충분히 균일화될 수 있도록 유동방향으로 소정의 두께를 갖는다.In particular, the honeycomb board 56 has a predetermined area of each honeycomb lattice 56a so as not to interfere with the flow of air flowing into the vent duct 52 from the air conditioning duct 50, and the air conditioning duct It has a predetermined thickness in the flow direction so that the flow of air flowing into the vent duct 52 at 50 is sufficiently uniform.

이와 같은 허니컴 보드(56)는 상기 공조덕트(50)에서 벤트덕트(52)로 유입되는 공기의 유동을 복수개의 벌집모양의 격자(56a)만큼 분산시킴으로써 상기 공조덕트(50)의 불균일한 유동이 상기 허니컴 보드(56)에 부딪치면서 와류 등이 소산되어 유동 저항이 감소되도록 하고, 공기 유동을 곧은 방향으로 유동되도록 안내한다. 따라서, 상기 허니컴 보디(56)를 거친 공기의 유동이 상기 벤트덕트(52)로 비교적 균일하게 유입된다.The honeycomb board 56 disperses the flow of air flowing into the vent duct 52 from the air conditioning duct 50 by a plurality of honeycomb lattices 56a, so that the nonuniform flow of the air conditioning duct 50 is reduced. While hitting the honeycomb board 56, vortices and the like are dissipated to reduce the flow resistance and guide the air flow to flow in a straight direction. Therefore, the flow of air passing through the honeycomb body 56 flows into the vent duct 52 relatively uniformly.

상기와 같이 구성되는 본 발명에 따른 차량용 공기조화시스템의 에어 덕트는 공기를 공조순서에 따라 안내하는 공조덕트와 상기 공조덕트에서 여러 갈래로 분기되어 공조된 공기를 차실로 안내하는 복수개의 벤트 덕트 사이에 벌집모양의 격자구조를 갖는 허니콤 보드가 설치되기 때문에 공기의 유동이 굴곡이 심한 공조덕트로 인해 불균일하더라도 상기 허니컴 보드에서 유동저항이 감소됨과 아울러 곧은 방향으로 안내되어 상기 벤트덕트로 유입되므로 상기 벤트덕트로 유입되는 공기의 유동이 비교적 균일하여 유동손실 및 유동소음을 줄일 수 있는 이점이 있다.An air duct of an air conditioning system for a vehicle according to the present invention configured as described above is provided between an air conditioning duct for guiding air in accordance with an air conditioning order and a plurality of vent ducts branched into the fork in the air conditioning duct to the vehicle compartment. Since the honeycomb board having a honeycomb lattice structure is installed in the air, the flow resistance in the honeycomb board is reduced and guided in the straight direction to flow into the vent duct even though the air flow is uneven due to the severe air conditioning duct. Since the flow of air introduced into the vent duct is relatively uniform, there is an advantage of reducing flow loss and noise.
