Description

열교환기 및 이를 가지는 실내기Heat exchanger and indoor unit with it
본 발명은, 공기조화 장치의 실내기에 사용되는 열교환기에 관한 것이다.The present invention relates to a heat exchanger used in an indoor unit of an air conditioner.
일반적으로 빌트-인(built-in) 타입의 공기조화 장치는 건물의 지붕과 천정 사이의 공간 등에 설치되는 실내기와, 냉매 배관 등을 통하여 상기 실내기와 접속되는 실외기를 구비한다.2. Description of the Related Art Generally, a built-in type air conditioner includes an indoor unit installed in a space between a roof of a building and a ceiling, and an outdoor unit connected to the indoor unit through a refrigerant pipe.
상기 실내기는 송풍기와, 상기 송풍기로부터 송풍되는 공기류가 통과하는 열교환기를 구비하고, 상기 열교환기를 통과한 공기류는, 건물 각처에 접속된 덕트로 흐른다.The indoor unit includes a blower and a heat exchanger through which the air flow blows from the blower, and the airflow that has passed through the heat exchanger flows into a duct connected to various places of the building.
건물의 전체 높이가 일정할 경우, 건물 실내의 천장의 높이를 키우게 되면, 건물의 지붕과 천장 사이의 공간의 높이가 줄어든다. 즉, 건물 실내의 천장의 높이에 의해 건물의 지붕과 천정 사이의 공간의 높이가 제한된다. 이로 인해, 건물의 지붕과 천정 사이의 공간의 높이 방향으로 설치 공간 한정되며, 건물의 지붕과 천정 사이의 공간에 실내기를 설치하기 위해서는 실내기의 높이 치수를 줄이는 것이 요구된다.If the overall height of the building is constant, increasing the height of the ceiling of the building reduces the height of the space between the roof and the ceiling of the building. That is, the height of the ceiling of the building limits the height of the space between the roof and the ceiling of the building. Therefore, the installation space is limited in the height direction of the space between the roof of the building and the ceiling. In order to install the indoor unit in the space between the roof of the building and the ceiling, it is required to reduce the height dimension of the indoor unit.
특허문헌 1에 기재된 발명에서는, 열교환기가 제1 열교환부와 제2 열교환부로 분할되어 각각이 90°의 각도를 이루고, 측면에서 볼 때 대략 “<(옆을 향한 V자 형상)“ 형상으로 연결되어 있다. 이와 같은 구조는, 열교환기를 연직 방향으로 세워서 송풍기의 송풍구에 대하여 그 면판부가 대향하도록 배치되는 구조와 비교하여, 실내기의 높이 치수를 줄일 수 있다.In the invention described in Patent Document 1, the heat exchanger is divided into the first heat exchanging portion and the second heat exchanging portion, each of which forms an angle of 90 ° and is connected in a substantially "<(side-facing V shape)" shape have. Such a structure can reduce the height dimension of the indoor unit as compared with a structure in which the heat exchanger is vertically arranged and arranged such that the face plate portion thereof is opposed to the air outlet of the blower.
그러나, 특허문헌 1에 기재된 발명의 구성에서는, 상기 제1 열교환부와 상기 제2 열교환부가 이루는 각도를 90°보다도 작게 할 수 없기 때문에, 높이 치수를 조정하기 어렵다.However, in the structure of the invention described in Patent Document 1, it is difficult to adjust the height dimension because the angle between the first heat exchanging portion and the second heat exchanging portion can not be made smaller than 90 degrees.
또한, 상기 제1 열교환부가 상기 제2 열교환부에 대하여 접하도록 배치되어 있으므로, 예를 들어 각각을 조합했을 때에 간섭이 발생하여 냉매 배관 등의 손상이 발생하지 않도록 하기 위해서는, 각 부재의 치수공차를 엄격하게 관리할 필요가 있다. 이로 인해, 조립 등에 기인하는 제조 비용을 저감하는 것이 어렵다는 문제도 있다.In addition, since the first heat exchanging portion is arranged to be in contact with the second heat exchanging portion, for example, in order to prevent the occurrence of interference with the refrigerant piping caused by the combination of the first heat exchanging portion and the second heat exchanging portion, It needs to be strictly controlled. As a result, there is a problem that it is difficult to reduce the manufacturing cost due to assembly and the like.

도 1 및 도 2에 도시한 바와 같이, 제1 열교환부(21)는 3매의 판 형상으로 형성된 제1 열교환 요소(23)가 각각의 면판 방향을 따라서 겹치지 않도록 배치되어 구성된다. As shown in Figs. 1 and 2, the first heat exchanging portion 21 is configured so that the first heat exchanging elements 23 formed in three plate shapes are arranged so as not to overlap each other along the face plate direction.
제1 열교환부(21)의 양단부는 코너와 평면이 교대로 형성된 계단 형상을 이룬다. 여기에서 말하는 평면이란 열교환 요소의 면판부의 일부를 이루는 것이다. 보다 구체적으로는, 제1 열교환부(21)에 있어서 상측에 배치되는 제1 계단 형상 단부(27)는 그 평면이 상방측을 향하고, 제1 열교환부(21)에 있어서 하측에 배치되는 제1 계단 형상 단부(25)는 그 평면이 하방측을 향하도록 배치된다. Both end portions of the first heat exchanging portion 21 have a stepped shape in which corners and planes are alternately formed. The plane referred to herein is a part of the face plate portion of the heat exchange element. More specifically, the first stepped end portion 27 disposed on the upper side of the first heat exchanging portion 21 has its plane directed upward, and the first stepped portion 27 disposed on the lower side of the first heat exchanging portion 21 The step-like end portion 25 is arranged so that its plane faces downward.
상측에 배치되는 제1 계단 형상 단부(27)는 케이싱(3)의 내부 상면에 설치된 상부 고정 구조(A1)에 의해 지지되고, 케이싱(3)과 제1 열교환부(21) 사이의 간극이 메워지도록 고정된다. The first stepped end portion 27 disposed on the upper side is supported by the upper fixing structure A1 provided on the inner upper surface of the casing 3 and the gap between the casing 3 and the first heat exchanging portion 21 is filled Respectively.
보다 구체적으로는, 제1 열교환부(21)에 있어서 가장 내측에 있는 제1 열교환 요소(23)의 상측단부와 케이싱(3)의 내부 상면 사이가 상부 고정 구조(A1)에 의해 막힌다. 여기서, 상측의 제1 계단 형상 단부(27)가 형성되어 있으므로, 2매째 및 3매째의 제1 열교환 요소(23)에 있어서의 상측의 단부는 상부 고정 구조(A1)가 설치되어 있는 부분보다 하측에 배치된다. More specifically, the upper fixing structure A1 blocks the space between the upper end of the first heat exchange element 23 located innermost in the first heat exchanging portion 21 and the upper surface of the casing 3. Here, since the first stepped end portion 27 on the upper side is formed, the upper end portion of the second and third heat exchange elements 23 is located lower than the portion where the upper fixing structure A1 is provided .
즉, 상부 고정 구조(A1)가 있음으로써 열교환을 수행하고 있지 않은 공기가 제1 열교환 요소(23)또는 제2 열교환 요소(24)를 통과할 수 있게 된다. 이와 같은 구조를 통해, 제1 열교환부(21)의 높이 방향으로 제1 열교환부(21)의 치수를 억제하면서, 열교환 효율을 높일 수 있다.That is, the presence of the upper fixing structure A1 makes it possible for the air not performing heat exchange to pass through the first heat exchanging element 23 or the second heat exchanging element 24. With this structure, the heat exchange efficiency can be increased while suppressing the dimension of the first heat exchanging portion 21 in the height direction of the first heat exchanging portion 21. [
도 1 및 도 2에 도시한 바와 같이, 제2 열교환부(22)는 3매의 판 형상으로 형성된 제2 열교환 요소(24)가 각각의 면판 방향을 따라서 겹치지 않도록 배치되어 구성된다. As shown in Figs. 1 and 2, the second heat exchanging section 22 is configured so that the second heat exchanging elements 24 formed in the form of three plates do not overlap along the direction of each face plate.
제1 열교환부(21)와 마찬가지로 제2 열교환부(22)의 단부는 코너와 평면이 교대로 형성된 계단 형상으로 가지도록 구성된다. 보다 구체적으로, 제2 열교환부(22)에 있어서 상측에 배치되는 제2 계단 형상 단부(26)는 그 평면이 상방측을 향하도록 되어 있고, 제2 열교환부(22)에 있어서 하측에 배치되는 제2 계단 형상 단부(28)는 그 평면이 하방측을 향하도록 배치되어 있다. Like the first heat exchanging portion 21, the end portion of the second heat exchanging portion 22 is configured so as to have a stepped shape in which corners and planes alternately form. More specifically, the second stepped end portion 26 disposed on the upper side of the second heat exchanging portion 22 has its plane directed upward, and the second stepped portion 26 disposed on the lower side of the second heat exchanging portion 22 The second stepped end 28 is disposed so that its plane faces downward.
하측에 배치되는 제2 계단 형상 단부(28)는 케이싱(3)의 내부 하면에 설치된 고정 구조(A2)에 의해 지지되고, 케이싱(3)과 제2 열교환부(22) 사이의 간극이 메워지도록 고정된다. The second stepped end portion 28 disposed on the lower side is supported by the fixing structure A2 provided on the inner bottom surface of the casing 3 so that the gap between the casing 3 and the second heat exchanging portion 22 is filled .
보다 구체적으로는, 제2 열교환부(22)에 있어서 가장 내측에 있는 제2 열교환 요소(24)의 하측단부와 케이싱(3)의 내부 하면 사이가 하부 고정 구조(A2)에 의해 막힌다. 여기서, 하측의 제2 계단 형상 단부(28)에 의해, 2매째 및 3매째의 제2 열교환 요소(24)에 있어서의 하측의 단부는 하부 고정 구조(A2)가 설치되어 있는 부분보다도 상측에 배치된다. More specifically, between the lower end of the second heat exchange element 24 located innermost in the second heat exchange section 22 and the inner bottom surface of the casing 3 is blocked by the lower fixing structure A2. Here, the lower second end 22 of the second and third heat exchange elements 24 is positioned above the lower fixing structure A2 by the second lower stepped end 28, do.
즉, 하부 고정 구조(A2)가 있음으로써 열교환을 수행하고 있지 않은 공기가 제1 열교환 요소(23)또는 제2 열교환 요소(24)를 통과할 수 있게 된다. 이와 같은 구조를 통해, 제2 열교환부(22)의 높이 방향의 치수를 억제하면서, 열교환 효율을 높일 수 있다.That is, the presence of the lower fixing structure A2 allows air that is not performing heat exchange to pass through the first heat exchanging element 23 or the second heat exchanging element 24. With this structure, the heat exchange efficiency can be increased while suppressing the dimension in the height direction of the second heat exchanging portion 22. [
제1 열교환부(21)의 하측 제1 계단 형상 단부(25)와, 제2 열교환부(22)의 상측 제2 계단 형상 단부(26)에 의해 연결부(2C)가 형성된다. 연결부(2C)는 측면에서 볼 때 제1 열교환부(21)와 제2 열교환부(22)가 90°보다 작은 소정 각도를 이루도록 구성된다. The connecting portion 2C is formed by the lower first stepped end portion 25 of the first heat exchanging portion 21 and the upper second stepped end portion 26 of the second heat exchanging portion 22. [ The connecting portion 2C is configured such that the first heat exchanging portion 21 and the second heat exchanging portion 22 form a predetermined angle smaller than 90 degrees when viewed from the side.
상기 소정 각도는, 제1 열교환부(21)의 면판부가 수평면에 대하여 이루는 각도와 제2 열교환부(22)의 면판부가 수평면에 대하여 이루는 각도의 총합이며, 40° 이상 90° 이하가 되도록 구성된다.The predetermined angle is a sum of an angle formed by the face plate portion of the first heat exchanging portion 21 with respect to the horizontal plane and an angle formed by the face plate portion of the second heat exchanging portion 22 with respect to the horizontal plane, .
제1 열교환부(21)와 제2 열교환부(22)가 이루는 상기 소정 각도와, 통풍 저항의 관계를 도 3의 그래프에 나타낸다. 그래프로부터 알 수 있는 바와 같이, 40° 이상 90° 이하로 소정 각도를 설정하면, 각 열교환부를 접은 상태에서 높이 방향의 치수를 억제하면서, 실내기(100)로서 동작시키기에 적합한 통풍 저항을 실현할 수 있다.The relationship between the predetermined angle formed by the first heat exchanging portion 21 and the second heat exchanging portion 22 and the ventilation resistance is shown in the graph of Fig. As can be seen from the graph, it is possible to realize the ventilation resistance suitable for operating as the indoor unit 100 while suppressing the dimension in the height direction in the state in which the respective heat exchanging portions are folded, by setting the predetermined angle to 40 degrees or more and 90 degrees or less .
또한, 도 1에 도시한 바와 같이, 제1 실시형태에서는, 제1 열교환부(21)의 면판부가 수평면에 대하여 이루는 각도가 제2 열교환부(22)의 면판부가 수평면에 대하여 이루는 각도보다 크게 되도록, 제1 열교환부(21)와 제2 열교환부(22)가 배치된다. 1, in the first embodiment, the angle formed by the face plate portion of the first heat exchanging portion 21 with respect to the horizontal plane is larger than the angle formed by the face plate portion of the second heat exchanging portion 22 with respect to the horizontal plane , A first heat exchanging part (21) and a second heat exchanging part (22) are arranged.
또한, 제1 열교환부(21)의 내측 면판부는, 제1 열교환부(21)의 내측 면판부를 송풍기(1) 측에 투영했을 경우, 분출구(11)를 대략 덮도록 분출구(11)와 대향하여 배치된다. When the inner face plate portion of the first heat exchanging portion 21 is projected to the blower 1 side, the inner face plate portion of the first heat exchanging portion 21 faces the air outlet 11 so as to substantially cover the air outlet 11 .
또한, 제1 실시형태에서는, 제1 열교환부(21) 및 제2 열교환부(22)가, 송풍기(1)의 분출구(11)로부터 수평하게 보았을 경우에, 튜브가 겹쳐지는 부분이 없도록 수평면에 대하여 경사지게 배치된다.In the first embodiment, when the first heat exchanging portion 21 and the second heat exchanging portion 22 are horizontally viewed from the air blow-out port 11 of the blower 1, As shown in FIG.
또한, 도 2에 도시한 바와 같이, 연결부(2C)에서, 모든 평면과 코너 사이에는 소정 거리의 간극이 형성된다. 즉, 제1 열교환부(21)와 제2 열교환부(22)는 연결부(2C)에서 서로 접촉하지 않도록 구성된다. 이 간극(도 2에 있어서 점선 동그라미로 도시)은 제1 열교환 요소(23) 및 제2 열교환 요소(24)의 치수공차나 조립 오차의 최대값보다 크게 설정되므로, 조립 시에 제1 열교환부(21)의 계단 형상 단부(25)가 제2 열교환부(22)의 계단 형상 단부(26)에 대하여 간섭이 발생하지 않는다. Further, as shown in Fig. 2, in the connecting portion 2C, a gap of a predetermined distance is formed between all the planes and the corners. That is, the first heat exchanging unit 21 and the second heat exchanging unit 22 are configured not to contact each other at the connecting portion 2C. Since the gap (shown by a dotted line in FIG. 2) is set to be larger than the maximum value of the dimensional tolerance or the assembly error of the first heat exchange element 23 and the second heat exchange element 24, the first heat exchange portion 21 do not interfere with the stepped end 26 of the second heat exchanging part 22.
제1 실시형태에서는 모든 코너와 평면 사이에 간극이 형성되어 있지만, 조립 용이성을 확보하기 위해서 적어도 하나의 코너와 평면 사이에 간극이 형성될 수도 있다.In the first embodiment, although a gap is formed between all the corners and the plane, a gap may be formed between at least one corner and a plane in order to ensure ease of assembly.
연결부(2C)에서, 송풍기(1)에 대하여 가장 외측에 있는 제1 열교환 요소(23)와 제2 열교환 요소(24)의 단부면 부분에는, 제1 열교환 요소(23)와 제2 열교환 요소(24) 사이의 간극을 막도록 V자 형상의 바람 차단판(4)이 설치될 수 있다.In the end portion of the first heat exchanging element 23 and the second heat exchanging element 24 which are at the outermost position with respect to the blower 1 in the connecting portion 2C the first heat exchanging element 23 and the second heat exchanging element 24, a V-shaped wind blocking plate 4 may be provided.
바람 차단판(4)이 설치되어 있지 않은 경우에는, 도 3에 도시한 바와 같이, 연결부(2C)의 간극으로 공기류가 집중되어, 1열의 열교환 요소만을 통과하는 경우가 발생한다. In the case where the wind blocking plate 4 is not provided, as shown in Fig. 3, the air flow is concentrated at the gap of the connecting portion 2C, and only the heat exchanging element of one row is passed.
도 2에 도시한 바와 같이, 바람 차단판(4)을 설치하면, 전체의 통풍 저항을 균일화할 수 있어, 제1 열교환부(21) 및 제2 열교환부(22)의 전체에 대하여 공기류가 통과하기 쉬워진다. As shown in Fig. 2, by providing the wind blocking plate 4, the entire ventilation resistance can be made uniform, and the airflow is made to flow through the entire first heat exchanging portion 21 and the second heat exchanging portion 22 It becomes easy to pass.
또한, 바람 차단판(4)에 의해 제1 계단 형상 단부(25)와 제2 계단 형상 단부(27)가 고정되므로, 연결부(2C)에서 각 단부에 간극을 형성하면서 조립하는 경우의 시인성을 양호하게 할 수 있다. 이로 인해, 각 열교환부를 간섭시키지 않고 조립 등을 용이하게 할 수 있게 되어, 조립성이 향상된다. Further, since the first stepped end portion 25 and the second stepped end portion 27 are fixed by the wind block 4, the visibility in the case of assembling while forming a gap in each end portion in the connecting portion 2C is good . As a result, it is possible to facilitate the assembly without interfering with each of the heat exchanging portions, and the assembling property is improved.
또한, 바람 차단판(2C)은 열교환기(2)에서 가장 하류측에 설치되어 있으므로, 예를 들어 제1 열교환부(21)에서 결로가 발생하여 핀 등을 타고 물방울이 하측의 제1 계단 형상 단부(25)나 연결부(2C) 내에 떨어지더라도 송풍기(1)의 공기류에 의해 이러한 물방울이 외부로 비산하는 것이 방지된다.In addition, since the wind blocking plate 2C is installed at the most downstream side in the heat exchanger 2, for example, condensation is generated in the first heat exchanging unit 21, Even when falling within the end portion 25 or the connecting portion 2C, the airflow of the blower 1 prevents such water droplets from scattering to the outside.
또한, 연결부(2C)에서, 제1 열교환부(21)에서 가장 송풍 덕트 접속구(32)에 가까운 부분과 제2 열교환부(22)에서 가장 송풍 덕트 접속구(32)에 가까운 부분이 연직 방향에 대하여 일렬로 배열되도록 각 열교환 요소가 배치된다. 즉, 제1 열교환부(21)의 각 지점으로부터 연직 방향 하향으로 수직선을 내렸을 경우에, 수직선이 제2 열교환기(2)와 교차하도록 구성된다. 따라서, 제1 열교환부(21)에서 발생하는 결로수가 제2 열교환부(22)로 낙하한 후, 제2 열교환부(22)를 타고 도시하지 않은 드레인을 통하여 배출될 수 있다.In the connecting portion 2C, a portion closest to the air duct connecting port 32 in the first heat exchanging portion 21 and a portion closest to the air duct connecting port 32 in the second heat exchanging portion 22 are arranged in the vertical direction Each heat exchange element is arranged to be arranged in a line. That is, when the vertical line is downward from the respective points of the first heat exchanging part 21 in the vertical direction, the vertical line intersects the second heat exchanger 2. Therefore, the condensation water generated in the first heat exchanging portion 21 can be discharged through the second heat exchanging portion 22 after draining into the second heat exchanging portion 22.
이와 같이 구성된 본 실시형태의 실내기(100)에 의하면, 제1 열교환부(21) 및 제2 열교환부(22)에서, 복수의 판 형상의 열교환 요소가 면판 방향을 따라서 겹치지 않도록 구성되고, 서로 대응하는 계단 형상의 단부의 조합으로 소정 각도를 이루도록 연결부(2C)가 구성되므로, 열교환기(2)의 수직 방향으로의 높이 치수를 억제할 수 있다.According to the indoor unit 100 of this embodiment configured as described above, the first heat exchanging unit 21 and the second heat exchanging unit 22 are constructed so that a plurality of plate-shaped heat exchanging elements do not overlap along the face plate direction, And the height of the heat exchanger 2 in the vertical direction can be suppressed.
또한, 연결부(2C)에서, 계단 형상 단부의 코너와 평면 사이에 간극이 형성됨으로써, 제1 열교환부(21) 및 제2 열교환부(22)의 치수공차나 조립 정밀도를 엄격하게 관리하지 않아도, 조립 시에 제1 열교환부(21) 및 제2 열교환부(22)가 서로 간섭되어 핀이나 튜브가 파손되는 것을 방지할 수 있다. 따라서, 열교환기(2)를 “<” 형상으로 절곡한 것과 같은 상태로 형성해도, 제조 비용의 상승을 억제할 수 있다.In addition, in the connecting portion 2C, a gap is formed between the corner of the step-like end portion and the plane, so that even if the dimensional tolerances and assembly precision of the first heat exchanging portion 21 and the second heat exchanging portion 22 are not strictly controlled, It is possible to prevent the first heat exchanging part 21 and the second heat exchanging part 22 from interfering with each other and damaging the fins and the tubes during assembly. Therefore, even when the heat exchanger 2 is formed in a state of being bent in the &quot; &quot; shape, an increase in manufacturing cost can be suppressed.
따라서 이와 같이 구성된 본 실시형태의 실내기(100)에 의하면, 지붕과 천장 사이의 공간을 가능한 한 작게 하고, 건물의 천장 높이를 높게 하여 거주 공간 등을 크게 하면서도, 저렴하면서, 종래와 동등한 냉동 효율을 가지는 공기조화 장치 구현하는 것이 가능하다.Thus, according to the indoor unit 100 of the present embodiment configured as described above, the space between the roof and the ceiling is made as small as possible, the height of the ceiling of the building is increased, It is possible to implement an air conditioner.
이어서 본 발명의 제2 실시형태에 관한 실내기(200)에 대하여 도 5를 참조하면서 설명한다.Next, an indoor unit 200 according to a second embodiment of the present invention will be described with reference to Fig.
제2 실시형태의 실내기(200)는 제1 실시형태의 실내기(100)와 동일한 연결부(2C)를 가진다. 제2 실시형태의 실내기(200)의 연결부(2C)는 제1 열교환부(21)와 제2 열교환부(22) 사이에 있는 공간을 메우도록 마련된 수지 충전체(5)를 더 포함한다. The indoor unit 200 of the second embodiment has the same connection portion 2C as that of the indoor unit 100 of the first embodiment. The connecting portion 2C of the indoor unit 200 of the second embodiment further includes a resin filling body 5 provided to fill a space between the first heat exchanging portion 21 and the second heat exchanging portion 22. [
수지 충전체(5)는, 측면에서 볼 때 제1 열교환부(21)의 제1 계단 형상 단부(25)와 제2 열교환부(22)의 제2 계단 형상 단부(26) 사이에 형성되는 공간의 단부면과 대략 동일 형상의 단부면을 갖는 등단면 형상의 기둥 형상체로 마련된다. The resin filling body 5 has a space formed between the first stepped end portion 25 of the first heat exchanging portion 21 and the second stepped end portion 26 of the second heat exchanging portion 22 as viewed from the side And has an end surface of substantially the same shape as that of the end surface of the rotor.
예를 들어, 제1 열교환부(21)와 제2 열교환부(22)를 케이싱(3)내에 설치한 후에 연결부(2C)에 대하여 측면으로부터 수지 충전체(5)를 삽입한다. 또한, 제2 열교환부(22)가 케이싱(3)에 설치된 후에 먼저 수지 충전체(5)를 제2 열교환부(22)의 계단 형상 단부(26)에 설치하고, 그 후, 제1 열교환부(21)를 그 계단 형상 단부(25)를 수지 충전체(5)에 대하여 맞추어가면서 설치할 수도 있다.For example, after the first heat exchanging portion 21 and the second heat exchanging portion 22 are installed in the casing 3, the resin filling body 5 is inserted into the connecting portion 2C from the side surface. After the second heat exchanging portion 22 is installed in the casing 3, the resin filling body 5 is first installed in the stepped end portion 26 of the second heat exchanging portion 22, (21) may be provided while aligning the stepped end (25) with the resin filler (5).
이와 같이 구성된 제2 실시형태의 실내기(200)에 의하면, 연결부(2C)에서의 간극을 모두 막고, 이 부분으로 송풍기(1)로부터 분출된 공기류가 통과할 수 없도록 하여 제1 열교환부(21) 및 제2 열교환부(22)로만 공기류가 통과하도록 할 수 있다. 따라서, 열교환기(2)의 열교환 효율을 더욱 높일 수 있다.According to the indoor unit 200 of the second embodiment configured as described above, the gaps in the connecting portion 2C are all closed, and the air flow ejected from the blower 1 is prevented from passing through the gaps and the first heat exchanging portion 21 ) And the second heat exchanging part (22). Therefore, the heat exchange efficiency of the heat exchanger 2 can be further increased.
또한, 연결부(2C)에 수지 충전체(5)가 배치됨으로써, 제1 열교환부(21)와 제2 열교환부(22)가 서로 간섭되는 것을 방지할 수 있고, 조립이 용이해지므로, 제조 비용을 더욱 저감할 수 있다. Since the resin filler 5 is disposed in the connecting portion 2C, it is possible to prevent the first heat exchanging portion 21 and the second heat exchanging portion 22 from interfering with each other, Can be further reduced.
또한, 수지 충전체(5)를 연속 발포체로 구성함으로써 제1 열교환부(21)로부터 제2 열교환부(22)로 결로수가 흐를 수 있는 유로를 확보하는 것이 가능하다. 즉, 수지 충전체(5)는 완전한 중실(中實)물질이 아니라, 미세한 다공질체를 포함하는 물질로 마련될 수도 있다.Further, by constituting the resin filling body 5 as a continuous foam, it is possible to secure a flow passage through which condensation water can flow from the first heat exchanging portion 21 to the second heat exchanging portion 22. [ That is, the resin filling body 5 may not be a complete solid substance but may be made of a material including a fine porous body.
이어서, 본 발명의 제3 실시형태에 관한 실내기(300)에 대하여 도 6을 참조하면서 설명한다.Next, an indoor unit 300 according to a third embodiment of the present invention will be described with reference to Fig.
제3 실시형태의 실내기(300)는 제1 실시형태의 실내기(100)와 동일한 연결부(2C)를 가진다. 제3 실시형태의 실내기(300)는, 제2 실시형태와 달리, 연결부(2C)의 모든 간극을 수지 충전체(5)로 막는 것이 아니다. The indoor unit 300 of the third embodiment has the same connection portion 2C as the indoor unit 100 of the first embodiment. Unlike the second embodiment, the indoor unit 300 of the third embodiment does not cover all the gaps of the connecting portion 2C with the resin filling body 5.
제3 실시형태의 실내기(300)의 연결부(2C)에서, 코너와 평면 사이는 수지 충전체(5)가 결합되고, 제1 열교환부(21)의 계단 형상 단부(25)로부터 제2 열교환부(22)의 계단 형상 단부(26)에 이르는 간극에 의해 적어도 하나의 유로(6)가 형성된다. 즉, 수지 충전체(5)를 복수로 분할함으로써, 적어도 하나의 유로(6)가 형성된다.In the connecting portion 2C of the indoor unit 300 according to the third embodiment, the resin filler 5 is coupled between the corner and the flat surface, and the second heat exchanging portion 5 is connected from the stepped end portion 25 of the first heat exchanging portion 21, At least one passage 6 is formed by a gap leading to the stepped end 26 of the valve body 22. That is, at least one flow path 6 is formed by dividing the resin filling body 5 into a plurality of parts.
이와 같이 구성된 제3 실시형태의 실내기(300)에 의하면, 송풍기(1)로부터 분출된 공기류가 연결부(2C)를 통과하기 어렵게 되고, 제1 열교환부(21)에서 발생한 결로수가 유로(6)를 지나 제2 열교환부(22)에 이른 후, 제2 열교환부(22)를 타고 드레인으로 배출된다.According to the indoor unit 300 of the third embodiment configured as described above, the airflow ejected from the blower 1 is less likely to pass through the connecting portion 2C, and the dew condensation generated in the first heat exchanging portion 21 is reduced, To the second heat exchanging part (22), and then discharged to the drain by the second heat exchanging part (22).
이어, 본 발명의 제4 실시형태에 관한 실내기(400)에 대하여 도 7을 참조하면서 설명한다.Next, an indoor unit 400 according to a fourth embodiment of the present invention will be described with reference to Fig.
제4 실시형태의 실내기(400)에서는, 열교환기(2)가 핀 앤드 튜브형이 아니라, 마이크로 채널형 열교환기(2)로 구성된다. 보다 구체적으로, 판 형상의 제1 열교환 요소(23) 및 제2 열교환 요소(24)는, 각각 다수의 마이크로 채널이 지면(紙面)의 깊이 방향으로 연장되는 편평관과, 각 편평관 사이에 예를 들어 코르게이트 핀이 끼워지도록 면판 방향을 따라서 적층된 형태로 마련된다.In the indoor unit 400 of the fourth embodiment, the heat exchanger 2 is not a pin-and-tube type but a microchannel-type heat exchanger 2. More specifically, the plate-shaped first heat exchanging element 23 and the second heat exchanging element 24 each have a flat tube in which a plurality of microchannels extend in the depth direction of the paper surface, So that the corrugated fin can be inserted.
이와 같이 구성된 제4 실시형태의 실내기(400)에 의하면, 공기류에 대한 열교환 효율을 더욱 높일 수 있고, 실내기(400)자체의 높이 치수를 보다 작게 하는 것도 가능해진다.According to the indoor unit 400 of the fourth embodiment configured as described above, the heat exchange efficiency with respect to the air flow can be further increased, and the height dimension of the indoor unit 400 itself can be made smaller.
