Description
본 발명은 공기조화기의 열교환기(예컨대, 증발기 또는 응축기)에 관한 것으로서, 더욱 상세하게는 핀(FIN)에 설치되는 루버(LOUVER)형 절기의 폭(단면) 및 높이가 기류의 유동방향으로 점차 커지도록 한 공기조화기의 열교환기에 관한 것이다.The present invention relates to a heat exchanger (eg, an evaporator or a condenser) of an air conditioner, and more particularly, a width (section) and a height of a louver-type season installed in a fin (FIN) in the flow direction of the airflow. It relates to a heat exchanger of an air conditioner that is gradually increased.
종래에 의한 공기조화기의 열교환기는, 도1a에 도시한 바와 같이, 소정간격을 두고 좌우 배치되는 2개의 지지판(10)과, 상기 지지판(10)의 사이에 상호 일정간격을 두고 가로방향으로 평행하게 배열되는 다수의 핀(20)과, 상기 2개의 지지판(10)과 다수의 핀(20)을 관통하여 확관됨과 동시에 상하 일정간격을 두고 배열되는 다수의 냉매관(30)과, 상기 2개의 지지판(10)의 외측으로 돌출된 상기 다수의 냉매관(30)의 끝단에 2조 한쌍씩 각각 연결되어 하나의 냉매 패스라인(PASS LINE)을 이루도록 하는 리턴 밴드관(40)으로 구성되어 있다.The heat exchanger of the conventional air conditioner, as shown in Figure 1a, is parallel to the horizontal direction at a predetermined interval between the two support plates 10, which are arranged left and right at a predetermined interval, and the support plate 10 A plurality of fins 20 arranged so as to be arranged, a plurality of refrigerant tubes 30 extending through the two support plates 10 and the plurality of fins 20 and arranged at regular intervals up and down, and the two It is composed of a return band pipe 40 is connected to each of the pair of pairs to each end of the plurality of refrigerant pipes 30 protruding out of the support plate 10 to form one refrigerant pass line (PASS LINE).
이와 같이 구성된 열교환기는, 냉매관(30)의 내부를 따라 냉매가 유동되면, 이 냉매의 온도가 냉매관(30)의 외주와 접하는 핀(20)으로 열전도됨으로써 이 열은 냉매관(30)의 중심으로부터 방사상으로 원형상의 등온선(等溫線)을 이루면서 핀(20)의 주변으로 점차 확산된다.In the heat exchanger configured as described above, when the coolant flows along the inside of the coolant pipe 30, the temperature of the coolant is thermally conducted to the fin 20 contacting the outer circumference of the coolant pipe 30. It gradually spreads around the fin 20 while forming a circular isotherm radially from the center.
이때, 기류는 화살표방향(S)과 같이 다수의 핀(20)들의 사이 사이를 통과하면서 핀(20)과 냉매관(30)의 표면에 접촉함으로써 핀(20)과 냉매관(30)에서 발생되는 냉매 온도에 의해 차갑거나 또는 뜨거운 기류로 열교환된다.At this time, the air flow is generated in the fin 20 and the refrigerant pipe 30 by contacting the surface of the fin 20 and the refrigerant pipe 30 while passing between the plurality of fins 20 as shown by the arrow direction (S). Heat exchanges with cold or hot air flow due to the refrigerant temperature.
그리고, 다수의 핀(20) 주위의 열유체 특성은 도1b에 도시한 바와 같이, 다수의 핀(20)의 전열면상의 온도경계층(P)의 두께가 기류의 유입부로부터의 거리의 제곱근에 비례하여 두꺼워지기 때문에 열교환율은 기류의 유입부 기류측으로부터의 거리가 증가함과 동시에 현저히 저하하며, 열교환기로서의 전열성능이 낮다는 결점을 가지고 있었다.In addition, as shown in FIG. 1B, the thermal fluid characteristic around the plurality of fins 20 is determined by the thickness of the temperature boundary layer P on the heat transfer surface of the plurality of fins 20 at a square root of the distance from the inlet of the airflow. The heat exchange rate has a drawback that the heat exchange rate significantly decreases as the distance from the inflow portion of the air flow increases, and the heat transfer performance as the heat exchanger is low because it becomes thick in proportion.
한편, 냉매관(30) 주위의 열유체 특성은 도1c에 도시한 바와 같이, 냉매관(30)에 화살표방향의 저풍속 기류가 유동하는 경우, 냉매관(30) 표면의 막힌 지점으로부터의 각도(θ)가 70-80°에서 흐름이 벗겨져 떨어지고, 냉매관(30)의 후방부에 사선으로 표시한 사류역(C)이 생기기 때문에 이 사류역(C)에서의 기류측 열전달율이 현저히 저함됨에 따라 전열성능이 낮다는 결점을 가지고 있었다.On the other hand, the heat fluid characteristics around the refrigerant pipe 30 is as shown in Figure 1c, when the low wind speed air flow in the direction of the arrow flows through the refrigerant pipe 30, the angle from the blocked point of the surface of the refrigerant pipe 30 (θ) flows off at 70-80 ° and drops off, and the airflow side heat transfer rate in this waterflow zone (C) is significantly lowered because the crossflow zone (C) indicated by the oblique line is formed at the rear portion of the refrigerant pipe (30). Therefore, the heat transfer performance was low.
그래서, 종래는 도2에 도시한 바와 같이, 다수의 핀(20)에 대하여 다수의 냉매관(30)들의 상하측 사이 간격에 다수의 루버형 절기(50,51,52,53)를 사선방향으로 경사지도록 각각 설치하여 왔다.Thus, conventionally, as shown in FIG. 2, a plurality of louver type seasons 50, 51, 52, 53 are diagonally disposed at intervals between the upper and lower sides of the plurality of refrigerant pipes 30 with respect to the plurality of fins 20. As shown in FIG. Each has been installed so as to be inclined.
즉, 상기 다수의 루버형 절기(50,51,52,53)는, 도3에 도시한 바와 같이, 기류의 유동방향으로 기반부가 없이 다이렉트로 연속 설치되며 또한 그들 절기폭(W)과 절기높이(H)가 모두 동일하도록 설치되어 있다.That is, the plurality of louver-type seasons 50, 51, 52, and 53, as shown in Fig. 3, are installed directly and continuously without a base in the flow direction of the airflow, and also their season width W and season height. (H) is provided so that all are the same.
그러나, 이와 같이 구성된 종래에 의한 공기조화기의 열교환기에 있어서, 핀(20)에 설치된 루버형 절기(50,51,52,53)는, 그 절기폭(W)과 절기높이(H)가 모두 동일하게 설치되어 있기 때문에 도3에 표시한 화살표방향(S)으로 기류가 유동될 경우 맨 앞쪽에 위치한 루버형 절기(50)에서 발생된 온도경계층이 루버형 절기(50)의 뒷쪽에 위치한 루버형 절기(51,52,53)의 온도경계층과 겹치게 됨에 따라 온도경계층 효과를 극대화시킬 수 없을 뿐만 아니라, 맨 앞쪽에 위치한 루버형 절기(50)를 통과하는 기류의 간섭작용때문에 뒷쪽에 위치한 루버형 절기(51,52,53)쪽을 기류가 제대로 유입되지 못함에 따라 난류화 효과도 극대화되지 못한다는 문제점이 있었다.However, in the heat exchanger of the conventional air conditioner configured as described above, the louver type seasons 50, 51, 52, and 53 provided in the fin 20 have both the season width W and the season height H. Since the airflow flows in the direction of the arrow S shown in FIG. 3, since the same installation, the temperature boundary layer generated at the front louver type season 50 is located at the rear of the louver type season 50. The overlapping temperature boundary layers of the seasons (51, 52, 53) are not only able to maximize the effect of the temperature boundary layer, but also the rear louver type seasons due to the interference of the airflow passing through the front louver type seasons (50). There was a problem that the turbulence effect was not maximized as the airflow was not properly introduced to the (51, 52, 53) side.
따라서, 본 발명은 상기 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 맨 앞쪽에 위치한 루버형 절기의 온도경계층이 뒷쪽에 위치한 루버형 절기의 온도경계층과 겹치지 않게 하여 온도경계층 효과를 극대화시킴과 동시에 맨 앞쪽에 위치한 루버형 절기를 통과한 기류가 뒷쪽에 위치한 루버형 절기로 유입될려는 기류의 흐름에 간섭을 주지 않게 하여 난류화 효과를 극대화시킬 수 있도록 한 공기조화기의 열교환기를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to maximize the temperature boundary layer effect by not overlapping the temperature boundary layer of the louver-type season located at the rear of the louver-type season located at the rear. At the same time, the airflow passing through the front louver season does not interfere with the flow of air to enter the rear louver season, thereby providing a heat exchanger for the air conditioner to maximize the turbulence effect. have.

상기 목적을 달성하기 위하여 이루어진 본 발명에 의한 공기조화기의 열교환기는, 기류가 유동되도록 소정 간격을 두고 평행하게 배열된 다수의 핀과, 상기 다수의 핀에 직각으로 삽입 배열된 다수의 냉매관을 구비한 공기조화기의 열교환기에 있어서, 상기 핀은, 기류의 유동방향으로 갈수록 절기폭(단면) 및 절기높이가 점차 커지는 다수의 루버형 절기를 포함하는 것을 특징으로 한다.The heat exchanger of the air conditioner according to the present invention made to achieve the above object, a plurality of fins arranged in parallel at a predetermined interval so that the air flow flows, and a plurality of refrigerant pipes inserted and arranged at right angles to the plurality of fins The heat exchanger of the air conditioner provided, characterized in that the fin comprises a plurality of louver-type seasons in which the season width (section) and the height of the season gradually increases toward the flow direction of the airflow.
이하, 본 발명의 일실시예에 관하여 첨부 도면을 참조하면서 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
참고로, 도면에서 종래의 구성과 동일한 구성에 대해서는 동일명칭 및 동일부호를 부여하고, 그에 대한 상세한 설명은 생략한다.For reference, the same components and the same reference numerals are assigned to the same components as the conventional components in the drawings, and detailed description thereof will be omitted.
본 발명에 의한 공기조화기의 열교환기는, 도4에 도시한 바와 같이, 기류가 유동되도록 소정 간격을 두고 평행하게 배열된 다수의 핀(20)과, 내부로 냉매가 유동되며 또한 상기 다수의 핀(20)에 직각으로 삽입 배열된 다수의 냉매관(30)과, 상기 다수의 핀(20)에 대하여 상기 다수의 냉매관(30)들의 상하측 사이 간격에 기류의 유동방향으로 갈수록 절기폭 및 절기높이가 점차 커지도록 동일한 경사각도로 각각 설치된 다수의 루버형 절기(60,61,62,63)로 구성되어 있다.The heat exchanger of the air conditioner according to the present invention, as shown in Figure 4, a plurality of fins 20 arranged in parallel at a predetermined interval so that the air flow flows, the refrigerant flows therein and also the plurality of fins A plurality of coolant tubes 30 inserted and arranged at right angles to the 20, and intervals between the upper and lower sides of the plurality of coolant tubes 30 with respect to the plurality of fins 20 in the flow direction of the air flow. Consists of a plurality of louver-type season (60, 61, 62, 63) installed at the same inclination angle so that the season height gradually increases.
또한, 상기 다수의 루버형 절기(60,61,62,63)들은, 동일한 경사방향에서 각각 경사각도가 서로 다르게 구성될 수도 있다.이때, 상기 다수의 루버형 절기(60,61,62,63)는, 도5에 도시한 바와 같이, 기류의 유동방향으로 기반부가 없이 다이렉트로 설치되면서 그 입구단이 상기 핀(20)의 이면으로 돌출되어 기류의 유동방향으로 개구되고, 그 출구단이 상기 핀(20)의 표면으로 돌출되어 기류의 유동반대방향으로 개구되어 있다.In addition, the plurality of louver type seasons 60, 61, 62, 63 may be configured to have different inclination angles in the same inclined direction, respectively. In this case, the plurality of louver type seasons 60, 61, 62, 63 As shown in FIG. 5, the inlet end protrudes to the rear surface of the fin 20 to be opened in the flow direction of the airflow while the base is directly installed without the base in the flow direction of the airflow. It protrudes to the surface of the fin 20, and is open in the direction opposite to the flow of airflow.
또, 상기 루버형 절기(60,61,62,63)는, 기류 유동방향을 따라 루버형 절기(60) ＜ 루버형 절기(61) ＜ 루버형 절기(62) ＜ 루버형 절기(63)의 수순으로 점차 절기폭과 절기높이가 커지도록 설치되어 있다.The louver type seasons 60, 61, 62, and 63 are made of louver type seasons 60 <louver type seasons 61 <louver type seasons <<louver type seasons 63 along the air flow direction. In order, the season width and season height are gradually increased.
다음은, 이와 같이 구성된 본 발명의 작용 및 효과를 설명한다.Next, the operation and effect of the present invention configured as described above will be described.
도5에 표시한 화살표방향(S)으로 기류가 유동되면, 이 기류는 핀(20)의 이면과 표면으로 양분되어 흐르다가 핀(20)의 소정위치에 설치된 다수의 루버형 절기(60,61,62,63)에 접촉됨으로써 난류화된다.When the airflow flows in the arrow direction S shown in FIG. 5, the airflow flows bilaterally to the back and the surface of the pin 20, and then a plurality of louver-type seasons 60 and 61 installed at predetermined positions of the pin 20. And 62, 63 to make it turbulent.
즉, 핀(20)의 이면측으로 흐르는 기류의 일부는 핀(20)의 이면으로 돌출된 루버형 절기(60,61,62,63)의 입구단을 통하여 점선화살표와 같이 유입됨과 동시에 핀(20)의 표면으로 돌출된 출구단을 통하여 유출되면서 핀(20)의 표면측으로 흐르는 본래의 기류와 충돌 및 혼합됨으로써 강한 난류를 형성하게 되고, 이로 인하여 핀(20)은 기류와 강한 접촉에 의해 높은 열교환이 이루어진다.That is, a part of the airflow flowing to the rear surface side of the fin 20 flows in the form of a dotted arrow through the inlet end of the louver type seasons 60, 61, 62, and 63 protruding to the rear surface of the fin 20, and at the same time, the fin 20 By colliding with and mixing with the original airflow flowing to the surface side of the fin 20 as it flows out through the outlet end protruding to the surface of), a strong turbulence is formed, whereby the fin 20 has a high heat exchange by strong contact with the airflow. This is done.
이때, 핀(20)에 설치된 루버형 절기(60,61,62,63)는, 절기높이가 모두 다르면서 기류의 유동방향으로 갈수록 점차 커지도록 루버형 절기(60) ＜ 루버형 절기(61) ＜ 루버형 절기(62) ＜ 루버형 절기(63)의 수순으로 설치되어 있기 때문에 기류가 유동될때 맨 앞쪽에 위치한 루버형 절기(60)에서 발생된 온도경계층이 뒷쪽에 위치한 루버형 절기(61,62,63)의 온도경계층과 겹치게 않게 되고, 그리고 루버형 절기(61)로부터 발생된 온도경계층은 뒷쪽에 위치한 루버형 절기(62,63)의 온도경계층과 겹치지 않게 되며, 그 다음 루버형 절기(62)로부터 발생된 온도경계층은 뒷쪽에 위치한 루버형 절기(63)의 온도경계층과 겹치지 않게 된다.At this time, the louver type seasons 60, 61, 62, and 63 installed in the pin 20 have different heights of the seasons and gradually increase in the flow direction of the airflow, and thus the louver type seasons 60 <louver type seasons 61 <Louver type season 62 <Since louver type season 63 is installed in order of airflow flows, when the airflow flows, the temperature boundary layer which generate | occur | produced in the louver type season 60 located in the front is located in the back. 62,63), and the temperature boundary layer generated from the louver-type season 61 does not overlap with the temperature boundary layer of the louver-type seasons 62,63 located at the rear, and then the louver-type season ( The temperature boundary layer generated from 62 does not overlap with the temperature boundary layer of the louver type season 63 located at the rear side.
따라서, 다수의 루버형 절기(60,61,62,63)들은 서로 온도경계층이 겹치지 않고 따로 온도경계층을 형성하기 때문에 온도경계층 효과를 극대화시킬 수 있다.Accordingly, the plurality of louver type seasons 60, 61, 62, and 63 may maximize the temperature boundary layer effect because the temperature boundary layers do not overlap each other and form a temperature boundary layer separately.
또한, 맨 앞쪽에 위치한 루버형 절기(60)를 통과하는 기류가 뒷쪽에 위치한 루버형 절기(61,62,63)쪽으로 각각 유입되는 기류에 간섭을 주지 않게 되고, 루버형 절기(61)를 통과하는 기류가 뒷쪽에 위치한 루버형 절기(62,63)쪽으로 각각 유입되는 기류에 간섭을 주지 않게 되며, 루버형 절기(62)를 통과하는 기류가 뒷쪽에 위치한 루버형 절기(63)쪽으로 유입되는 기류에 간섭을 주지 않게 된다.In addition, the air flow passing through the louver-type season 60 located at the very front does not interfere with the airflow flowing into the louver-type seasons 61, 62, and 63 located at the rear, and passes through the louver-type season 61. The air flow does not interfere with the air flows toward the louver-type seasons 62 and 63 located at the rear side, and the air flow passing through the louver-type seasons 62 is introduced into the louver-type season 63 located at the rear side. Will not interfere with.
따라서, 다수의 루버형 절기(60,61,62,63)들은 서로 기류흐름에 간섭을 주지 않게 됨으로, 난류화 효과를 극대화시킬 수 있다.Therefore, the plurality of louver-type seasons (60, 61, 62, 63) do not interfere with each other air flow, it is possible to maximize the turbulence effect.
그리고, 루버형 절기(60,61,62,63)는, 절기폭(면적)이 모두 다르면서 기류의 유동방향으로 갈수록 점차 커지도록 루버형 절기(60) ＜ 루버형 절기(61) ＜ 루버형 절기(62) ＜ 루버형 절기(63)의 수순으로 설치되어 있기 때문에 기류가 후방으로 갈수록 열전달율이 저하되는 것을 미연에 방지할 수 있다.The louver type seasons 60, 61, 62, and 63 have different season widths (areas) and are gradually increased in the flow direction of the airflow, and thus, louver type seasons 60 <louver type seasons 61 <louver type Since the season 62 is provided in the order of the louver-type season 63, it is possible to prevent the heat transfer rate from decreasing as the air flows backward.
그 이유는, 단면이 넓으면 넓을수록 기류와 접촉되어 열을 빼앗기는 속도가 느리기 때문이다.The reason for this is that the wider the cross section, the slower the speed of contact with the airflow and the heat is taken away.
이상 설명한 바와 같이, 본 발명에 의한 공기조화기의 열교환기는, 루버형 절기의 면적이 기류의 유동방향으로 점차 넓어지도록 설치함과 동시에 루바형 절기의 높이가 기류의 유동방향으로 점차 높아지도록 설치한 구조로 되어 있기 때문에 맨 앞쪽에 위치한 루버형 절기의 온도경계층이 뒷쪽에 위치한 루버형 절기의 온도경계층과 겹치지 않게 하여 온도경계층 효과를 극대화시킴과 동시에 맨 앞쪽에 위치한 루버형 절기를 통과한 기류가 뒷쪽에 위치한 루버형 절기로 유입될려는 기류의 흐름에 간섭을 주지 않게 하여 난류화 효과를 극대화시킬 수 있는 것이다.As described above, the heat exchanger of the air conditioner according to the present invention is installed so that the area of the louver season is gradually widened in the flow direction of the airflow, and the height of the luba season is gradually increased in the flow direction of the airflow. Because of this structure, the temperature boundary layer of the front louver season does not overlap with the temperature boundary layer of the louver season located at the rear, maximizing the effect of the temperature boundary layer and at the same time, the airflow passing through the front louver season at the rear It is possible to maximize the turbulence effect by not interfering with the flow of airflow to be introduced into the louver-type season located at.
