Abstract

A heat exchanger having tubes aligned in two rows is provided to differ tube pitches in front and rear rows according to positions of inlet and outlet pipes for preventing concentration of refrigerant, thereby improving heat exchange performance. In a heat exchanger having tubes aligned in two rows, a tube pitch(Ptube) between neighboring tubes(30) becomes different according to positions of inlet and outlet pipes(11,12). The tube pitch between tubes in a row(A) provided with the inlet pipe becomes decreased gradually in the lengthwise direction of upper and lower tanks(10,20) from the inlet pipe. The tube pitch between tubes in the other row(B) provided with the outlet pipe becomes increased gradually in the lengthwise direction of upper and lower tanks from the inlet pipe.

본 발명은 2열 열교환기에 관한 것으로서 전, 후열을 갖는 2열 열교환기에 있어서 냉각수가 유입되는 열과 배출되는 열의 튜브 피치가 다르도록 형성되어 열교환효율을 더욱 높일 수 있는 2열 열교환기를 제공함에 있다.The present invention relates to a two-column heat exchanger in a two-column heat exchanger having a front and back heat, so that the tube pitch of the heat entering the coolant and the discharged heat is different from each other to further improve the heat exchange efficiency.

근래 자동차 산업에 있어서 세계적으로 환경과 에너지에 대한 관심이 높아짐에 따라 연비 개선을 위한 연구가 이루어지고 있으며 다양한 소비자의 욕구를 만족시키기 위해 경량화·소형화 및 고기능화를 위한 연구개발이 꾸준히 이루어지고 있다. In recent years, as the interest in the environment and energy in the automobile industry is increasing, researches for improving fuel efficiency have been made, and research and development for light weight, miniaturization, and high functionalization have been steadily performed to satisfy various consumer needs.

특히, 열교환기는 온도차가 있는 두 환경 사이에서 한쪽의 열을 흡수하여 다른 쪽으로 열을 방출시키는 장치로서, 기본적으로 열교환기는 주변으로부터 열을 흡수하는 증발기, 냉각수를 압축하는 압축기, 주변으로 열을 방출하는 응축기, 냉각수를 팽창시키는 터빈(또는 팽창밸브)으로 구성된다. In particular, a heat exchanger is a device that absorbs heat from one side and dissipates heat between the two environments with different temperatures, and basically a heat exchanger is an evaporator that absorbs heat from the surroundings, a compressor that compresses cooling water, Condenser, turbine (or expansion valve) for expanding the cooling water.

상기 열교환기는 액상의 냉각수가 기체상태로 변화하는 과정에서 송풍장치에 의해 유입된 공기를 열교환에 의해 냉각되도록 하여 차가워진 공기를 차량의 실내로 공급되도록 할 경우에는 냉방 장치로서 작동하고, 외부로부터 열을 흡수하여 따뜻해진 공기를 실내로 방출 할 경우에는 난방 장치로 작용하게 된다. The heat exchanger operates as a cooling device to cool the air introduced by the blower in the process of changing the liquid coolant into the gas state by heat exchange to supply the cooled air to the interior of the vehicle. When it absorbs and releases warmed air into the room, it acts as a heating device.

그러나 상술한 바와 같이 자동차의 경량화·소형화 추세에 따라 자동차 내부 에서 충분한 공간을 확보하기 어려운 실정이기 때문에 작은 크기를 가지면서도 높은 효율을 가지는 열교환기를 제조하기 위한 노력이 있어왔다.However, as described above, due to the light weight and miniaturization of the automobile, it is difficult to secure sufficient space inside the vehicle. Therefore, efforts have been made to manufacture a heat exchanger having a small size and high efficiency.

도 1은 종래의 2열 열교환기의 사시도로 도시된 바와 같이, 상기 2열 열교환기는 상단탱크(110) 및 하단탱크(120)와; 상기 상단탱크(110) 및 하단탱크(120)에 고정되고 전, 후열을 갖는 다수개의 튜브(130)와; 상기 튜브(130) 사이에 적층되는 복수개의 핀(140)으로 이루어진다. 상기 도 1에 도시된 열교환기는 상기 상단탱크(110)에 일측에 입구파이프(111)와 출구파이프(112)가 구비되고 상기 상단탱크(110)에 배플이 구비되어 2개의 격실이 존재하는 일 실시예를 도시하였다. 1 is a perspective view of a conventional two-row heat exchanger, the two-row heat exchanger and the upper tank 110 and the lower tank 120; A plurality of tubes 130 fixed to the upper tank 110 and the lower tank 120 and having a front and rear rows; It consists of a plurality of fins 140 stacked between the tube 130. The heat exchanger illustrated in FIG. 1 is provided with an inlet pipe 111 and an outlet pipe 112 at one side of the upper tank 110, and a baffle is provided at the upper tank 110. An example is shown.

도 2는 종래의 2열 열교환기의 분해사시도로 종래의 2열 열교환기는 냉각수의 흐름과는 관계없이 2열 열교환기 전체에 대하여 상기 전열과 후열의 튜브 피치는 같게 형성되어 있다. FIG. 2 is an exploded perspective view of a conventional two-row heat exchanger. In the conventional two-row heat exchanger, the tube pitches of the heat transfer and the post-heat treatment are the same for the entire heat exchanger regardless of the flow of cooling water.

상기한 바와 같이 구성된 종래의 2열 열교환기는 입구파이프가 구비된 열에서 상기 입구파이프에 가까운 부분에 냉매가 편중되고 출구파이프가 구비된 열에서 상기 출구파이프로부터 먼 부분에 냉매가 편중되는 문제점이 있었다. 이에 따라, 냉매가 편중되는 부분에서 충분히 열교환되지 못하게 되므로 자동차 내부의 좌·우 온도차이가 발생되는 문제점이 있고 열교환효율이 떨어짐에 따라 사용자의 온도 쾌적성을 떨어뜨리는 문제점이 있었다.The conventional two-row heat exchanger configured as described above has a problem in that the refrigerant is concentrated in a portion close to the inlet pipe in the heat provided with the inlet pipe, and the refrigerant is concentrated in the portion away from the outlet pipe in the heat provided with the outlet pipe. . Accordingly, there is a problem in that the left and right temperature difference occurs inside the vehicle because the refrigerant is not sufficiently heat exchanged in the portion in which the refrigerant is biased, and the temperature comfort of the user is lowered as the heat exchange efficiency decreases.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 전열과 후열의 튜브를 갖는 2열 열교환기에 있어서, 상기 2열 열교환기에 구비된 입구파이프와 출구파이프의 위치에 따라 상기 전열과 후열의 이웃하는 튜브 간 거리인 튜브 피치가 다르게 구비되어 냉매 편중을 방지함으로써 2열 열교환기의 열교환 성능을 향상시킬 수 있는 2열 열교환기를 제공함에 있다. Accordingly, the present invention has been made to solve the above problems, the object of the present invention is a two-row heat exchanger having a tube of heat transfer and after heat, according to the position of the inlet pipe and the outlet pipe provided in the heat exchanger It is to provide a two-row heat exchanger that can improve the heat exchange performance of the two-row heat exchanger by preventing the bias of the refrigerant is provided with a different tube pitch, which is the distance between the neighboring tube of the heat transfer and the after heat.

또한, 본 발명에 따른 다른 목적은 좌우의 온도차를 최소화하여 자동차 내부의 온도쾌적성을 유지할 수 있도록 하는 2열 열교환기를 제공함에 있다. In addition, another object of the present invention is to provide a two-row heat exchanger to minimize the temperature difference between the left and right to maintain the temperature comfort inside the vehicle.

상기의 목적을 달성하기 위한 본 발명의 2열 열교환기는 입구파이프 및 출구파이프가 각각 구비되고 일정거리 이격되어 나란하게 형성된 상단탱크 및 하단탱크와; 상기 상단탱크와 하단탱크를 연결하고 전, 후열을 갖는 다수개의 튜브와; 상기 튜브 사이에 적층되는 복수개의 핀을 포함하는 2열 열교환기에 있어서, 상기 입구파이프 및 출구파이프의 위치에 따라 이웃하는 튜브 간 거리인 튜브 피치가 다르게 형성되는 것을 특징으로 한다.The two-row heat exchanger of the present invention for achieving the above object is provided with an inlet pipe and an outlet pipe, respectively, the upper and lower tanks are formed side by side spaced apart; A plurality of tubes connecting the upper tank and the lower tank and having a front row and a rear row; In a two-row heat exchanger including a plurality of fins stacked between the tubes, the tube pitch, which is the distance between neighboring tubes, is formed differently according to the positions of the inlet pipe and the outlet pipe.

아울러, 상기 입구파이프가 구비된 열의 튜브 피치는 상기 입구파이프로부터 상기 탱크의 길이방향으로 진행됨에 따라 점차적으로 작아지는 것을 특징으로 한다.In addition, the tube pitch of the row provided with the inlet pipe is characterized in that it gradually decreases as it runs in the longitudinal direction of the tank from the inlet pipe.

또한, 상기 출구파이프가 구비된 열의 튜브 피치는 상기 출구파이프로부터 상기 탱크의 길이방향으로 멀어짐에 따라 점차적으로 커지는 것을 특징으로 한다.In addition, the tube pitch of the row provided with the outlet pipe is characterized in that it gradually increases as the distance from the outlet pipe in the longitudinal direction of the tank.

이하, 상기한 바와 같은 구성을 가지는 본 발명의 2열 열교환기를 첨부된 도 면을 참조로 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings, the two-row heat exchanger of the present invention having the configuration as described above will be described in detail.

본 발명에서 설명하는 튜브 피치(Ptube)는 상기 튜브(30)와 튜브(30) 사이의 거리를 나타내며, 상기 튜브(30) 사이에 핀(40)이 적층되므로 핀 높이(Hfin)와 같은 의미를 갖는다.Tube pitch (P tube ) described in the present invention represents the distance between the tube 30 and the tube 30, pin 40 is stacked between the tube 30, such as fin height (H fin ) Has meaning.

본 발명의 2열 열교환기는 입구파이프(11) 및 출구파이프(12)가 각각 구비되고 일정거리 이격되어 나란하게 형성된 상단탱크(10) 및 하단탱크(20)와; 상기 상단탱크(10)와 하단탱크(20)를 연결하고 전, 후열을 갖는 다수개의 튜브(30)와; 상기 튜브(30) 사이에 적층되는 복수개의 핀(40)을 포함한다.The two-column heat exchanger of the present invention includes an inlet pipe 11 and an outlet pipe 12, respectively, and includes an upper tank 10 and a lower tank 20 formed side by side at a predetermined distance from each other; A plurality of tubes 30 which connect the upper tank 10 and the lower tank 20 and have before and after rows; It includes a plurality of fins 40 stacked between the tube (30).

이와 같이 형성된 상기 2열 열교환기의 내부에 유통되는 냉매는 상기 입구파이프(11)를 통해 상기 상단탱크(10)로 냉각수가 유입되어 상기 상단탱크(10)의 길이방향을 따라 냉각수가 이동되어 상기 전열을 형성하는 튜브(30)를 통해 상기 하단탱크(20)로 유입되고 상기 하단탱크(20)를 통해 후열을 형성하는 튜브(30)를 통해 다시 상단탱크(10)로 유입되어 상기 상단탱크(10)에 형성된 출구파이프(12)를 통해 배출되는 구조를 가진다. The coolant circulated in the two-row heat exchanger formed as described above is introduced into the upper tank 10 through the inlet pipe 11 to move the cooling water along the longitudinal direction of the upper tank 10. The upper tank 10 is introduced into the lower tank 20 through the tube 30 forming the heat transfer and flows back into the upper tank 10 through the tube 30 forming the rear heat through the lower tank 20. It has a structure that is discharged through the outlet pipe 12 formed in 10).

상기한 바와 같은 2열 열교환기는 상기 입구파이프에 가까운쪽과 상기 출구파이프에 먼쪽에 냉매가 편중되어 충분한 열교환이 이루어 지지 않음에 따라 자동차 실내로 토출되는 풍량의 좌우 온도차이가 발생되는 문제점이 있었다.As described above, the two-column heat exchanger has a problem in that left and right temperature differences between the inlet pipes and the outlet pipes are biased so that a sufficient heat exchange is not performed and thus the left and right temperature differences of the air volume discharged to the vehicle interior are generated.

상기한 바와 같은 문제점을 해결하기 위한 본 발명의 2열 열교환기는 입구파이프(11) 및 출구파이프(12)가 각각 구비된 상단탱크(10) 및 하단탱크(20)와; 상기 상단탱크(10)와 하단탱크(20)를 연결하고 전, 후열을 갖는 다수개의 튜브(30)와, 상기 튜브(30) 사이에 적층되는 복수개의 핀(40)을 포함하는 2열 열교환기에 있어서, 상기 입구파이프(11) 및 출구파이프(12)의 위치에 따라 이웃하는 튜브 간 거리인 튜브 피치(Ptube)가 다르게 형성되는 것을 특징으로 한다. 상기 입구파이프(11)가 구비된 열(A)의 튜브 피치(Ptube)는 상기 입구파이프(11)로부터 상기 탱크의 길이방향으로 진행됨에 따라 점차적으로 작아지고, 상기 출구파이프(12)가 구비된 열(B)의 튜브 피치(Ptube)는 상기 출구파이프(12)로부터 상기 탱크의 길이방향으로 멀어짐에 따라 점차적으로 커지는 것을 특징으로 한다.Two-column heat exchanger of the present invention for solving the problems as described above and the upper tank 10 and the lower tank 20 is provided with an inlet pipe 11 and outlet pipe 12, respectively; The upper tank 10 and the lower tank 20 is connected to a two-column heat exchanger including a plurality of tubes 30 having front and rear rows, and a plurality of fins 40 stacked between the tubes 30. In this case, according to the position of the inlet pipe 11 and the outlet pipe 12 is characterized in that the tube pitch (P tube ) which is the distance between the neighboring tube is formed differently. The tube pitch P tube of the row A provided with the inlet pipe 11 gradually decreases from the inlet pipe 11 in the longitudinal direction of the tank, and the outlet pipe 12 is provided. The tube pitch P tube of the row B is gradually increased as it moves away from the outlet pipe 12 in the longitudinal direction of the tank.

본 발명의 2열 열교환기는 입구파이프(11)가 구비된 열(A)에만 상기 입구파이프(11)로부터 상기 탱크의 길이방향으로 진행됨에 따라 상기 튜브 피치(Ptube)가 점차적으로 작아지도록 형성될 수 있고, 상기 출구파이프(12)가 구비된 열(B)에만 상기 출구파이프(12)로부터 상기 탱크의 길이방향으로 멀어짐에 따라 상기 튜브 피치(Ptube)가 점차적으로 커지도록 형성될 수 있다.The two-column heat exchanger of the present invention may be formed such that the tube pitch (P tube ) gradually decreases from the inlet pipe (11) to the tank (A) having the inlet pipe (11) in the longitudinal direction of the tank. The tube pitch (P tube ) may be formed to gradually increase in the longitudinal direction of the tank from the outlet pipe 12 only in the row (B) provided with the outlet pipe (12).

도 3은 본 발명의 2열 열교환기의 일실시예를 나타낸 분해사시도이고, 도 4는 상기 도 3에 도시된 상단탱크(10)의 하면을 나타낸 정면도로 도시된 바와 같이 상기 입구파이프(11)가 구비된 열(A)과 상기 출구파이프(12)가 구비된 열(B) 모두 에 튜브 피치(Ptube)가 달라지도록 형성될 수 있다.Figure 3 is an exploded perspective view showing an embodiment of a two-row heat exchanger of the present invention, Figure 4 is a front view showing a lower surface of the upper tank 10 shown in Figure 3 the inlet pipe 11 The tube pitch (P tube ) may be formed in both the column (A) provided with the column (B) provided with the outlet pipe (12).

상기 입구파이프(11)가 구비된 열(A)의 튜브 피치(Ptube)가 상기 입구파이프(11)로부터 상기 탱크의 길이방향으로 진행됨에 따라 점차적으로 작아짐으로써, 보다 상기 입구파이프(11)로부터 멀리 떨어진 곳까지 상기 냉각수가 빠르게 이동되어 상기 입구파이프(11)와 가까운 부분에 냉매가 편중되어 충분히 열교환되지 않는 문제점을 해결할 수 있게 된다.The tube pitch P tube of the row A provided with the inlet pipe 11 gradually decreases as it travels from the inlet pipe 11 in the longitudinal direction of the tank, thereby further reducing the inlet pipe 11 from the inlet pipe 11. The coolant is rapidly moved to a far place so that the refrigerant is concentrated in a portion close to the inlet pipe 11 and thus the heat exchange is not sufficiently performed.

아울러, 상기 출구파이프(12)가 구비된 열(B)의 튜브 피치(Ptube)는 상기 출구파이프(12)로부터 상기 탱크의 길이방향으로 멀어짐에 따라 점차적으로 커지게 되고 상기 출구파이프(12)와 가까운 쪽의 튜브 피치(Ptube)는 작아진다.In addition, the tube pitch (P tube ) of the row (B) provided with the outlet pipe 12 is gradually increased in the longitudinal direction of the tank from the outlet pipe 12 and the outlet pipe 12 The tube pitch (P tube ) near the side becomes smaller.

도 5는 상기 도 3의 입구파이프(11)가 구비된 열(A)의 확대도로 상기 입구파이프(11)와 가까운 쪽에 위치한 부분은 도 5 (a)와 같이 튜브 피치(Ptube)가 크게 형성되고, 도 5 (b)와 같이 상기 입구파이프(11)에서 상기 탱크 길이방향으로 진행됨에 따라 점차적으로 작아진다.FIG. 5 is an enlarged view of a row A provided with the inlet pipe 11 of FIG. 3, and the portion located near the inlet pipe 11 has a large tube pitch P tube as shown in FIG. 5A. As shown in FIG. 5 (b), the inlet pipe 11 gradually decreases as it proceeds in the tank longitudinal direction.

도 6은 상기 도 3의 출구파이프(12)가 구비된 열(B)의 확대도로 상기 출구 파이프와 가까운 쪽에 위치한 부분은 도 6 (a)와 같이 튜브 피치(Ptube)가 크게 형성되고, 상기 출구파이프(12)에서 상기 탱크 길이방향으로 멀어질수록 상기 튜브(30)피치는 상기 도 6 (b)와 같이 점차적으로 커지게 된다.Figure 6 is formed of a tube pitch (P tube) larger as enlarged the outlet 6 portion is located on the side close to the pipe Fig. (A) of column (B) equipped with a outlet pipe 12 of Figure 3, the The farther away from the outlet pipe 12 in the tank longitudinal direction, the pitch of the tube 30 becomes larger as shown in FIG. 6 (b).

도 6에 도시된 2열 열교환기는 상단탱크(10) 내부에 배플이 형성되어 2개의 격실이 형성되고 상기 상단탱크(10)의 일측에 입구파이프(11) 및 출구파이프(12)가 형성된 일 실시예를 도시하였으며, 본 발명의 2열 열교환기는 상기 입구파이프(11) 및 출구파이프(12)가 구비되는 위치 및 냉매의 흐름에 따라 다양하게 적용가능한 것은 당연하다.The two-row heat exchanger illustrated in FIG. 6 is a baffle formed inside the upper tank 10 so that two compartments are formed, and an inlet pipe 11 and an outlet pipe 12 are formed at one side of the upper tank 10. For example, the two-column heat exchanger of the present invention may be variously applied depending on the location of the inlet pipe 11 and the outlet pipe 12 and the flow of the refrigerant.
