Description

에어컨용 열교환기{heat exchanger for air conditioner}Heat exchanger for air conditioners

본 발명은 에어컨용 열교환기에 관한 것으로써, 좀더 구체적으로는 구조를 개선하여 열교환 면적을 극대화시킬 수 있도록 한 것이다.The present invention relates to a heat exchanger for an air conditioner, and more particularly, to improve the structure to maximize the heat exchange area.

도 1은 종래의 열교환기를 나타낸 사시도로써, 지그재그로 절곡된 냉매파이프(1)의 외주면에 판상으로 형성된 다수매의 냉각핀(2)을 압입고정하여 열교환기를 구성하도록 되어 있는데, 이때 냉매파이프가 절곡되는 부위(이하 리턴 밴드라 함)에는 냉각핀을 위치시키지 못하게 되므로 상기 리턴 밴드(3)는 냉매의 유로역할만을 하게 된다.1 is a perspective view showing a conventional heat exchanger, and press-fits and fixes a plurality of cooling fins 2 formed in a plate shape on the outer circumferential surface of the refrigerant pipe 1 bent in a zigzag shape, wherein the refrigerant pipe is bent. Since the cooling fins cannot be located at a portion (hereinafter referred to as a return band), the return band 3 serves only as a flow path of the refrigerant.

상기한 바와 같은 구조로 이루어진 열교환기는 에어컨의 본체에 부착할 때 본체내에 장착된 송풍팬(도시는 생략함)의 구동에 따라 실내의 공기가 통과되면서 열교환이 이루어지는 부위를 제외한 나머지부분인 리턴 밴드(3)부분은 샤시에 부착되어 밀폐된다.The heat exchanger having the structure as described above has a return band (except for a portion where heat exchange is performed while the air in the room passes through the operation of a blower fan (not shown) mounted in the main body when attached to the main body of the air conditioner) 3) The part is attached to the chassis and sealed.

이러한 구조의 열교환기는 송풍팬의 구동에 의해 실내의 공기가 본체의 내부로 유입될 때 상기 공기는 냉각핀부분만을 통과하면서 열교환작용을 하게 되므로 냉각핀(2)의 외부로 노출된 리턴 밴드(3)부분은 열교환작용이 이루어지지 못하게 되고, 이에 따라 에어컨의 냉방능력인 효율이 저하되었음은 물론 열교환기의 콤팩트실현이 어렵게 되었다.The heat exchanger having such a structure has a return band (3) exposed to the outside of the cooling fin (2) because the air is exchanging heat while passing through the cooling fin only when the air in the room is introduced into the main body by driving the blower fan. The heat exchange effect of the a) part is not achieved, and as a result, the cooling efficiency of the air conditioner is lowered, and the compact realization of the heat exchanger becomes difficult.

본 발명은 종래의 이와 같은 문제점을 해결하기 위해 안출한 것으로써, 냉각핀의 외부로 노출되는 리턴 밴드부분에서도 열교환작용이 일어나도록 그 구조를 달리하여 열교환능력이 증대되도록 함과 함께 열교환기의 콤팩트화 실현이 가능해지도록 하는데 그 목적이 있다.The present invention has been made to solve such a problem in the prior art, the heat exchange capacity is increased by changing the structure so that the heat exchange action also occurs in the return band portion exposed to the outside of the cooling fins and the heat exchanger compact The goal is to make it possible.

상기 목적을 달성하기 위한 본 발명의 형태에 따르면, 지그재그로 절곡된 냉매파이프의 외주면에 다수매의 냉각핀을 압입 고정하고, 상기 냉각핀의 양측으로는 외부로 노출되게 리턴 밴드를 고정한 것에 있어서, 다수매의 냉각핀중 가장 좌,우측의 냉각핀 전,후에 상기 냉각핀과 직교되는 방향으로 각각 전면판넬과 후면판넬을 일체 형성하고, 상기 전면판넬에는 공기흡입구를 형성함과 함께 후면판넬에는 공기토출구를 형성하여 상기 공기흡입구를 통해 흡입된 공기가 전면판넬과 후면판넬 사이의 공간부에 머무르면서 리턴 밴드부분과 열교환을 행한 다음 공기토출구를 통해 토출되도록 한 에어컨용 열교환기가 제공된다.According to an aspect of the present invention for achieving the above object, by pressing-fixing a plurality of cooling fins to the outer peripheral surface of the refrigerant pipe bent in a zigzag, and fixed to the return band to be exposed to the outside on both sides of the cooling fins, Among the plurality of cooling fins, the front panel and the rear panel are integrally formed in the direction orthogonal to the cooling fins before and after the left and right cooling fins, and the air inlet is formed on the front panel and the air is formed on the rear panel. There is provided a heat exchanger for an air conditioner which forms a discharge port so that the air sucked through the air suction port stays in the space between the front panel and the rear panel, performs heat exchange with the return band portion, and then discharges it through the air discharge port.

첨부된 도 2a ∼ 도 2d는 본 발명 열교환기를 나타낸 사시도로써, 본 발명의 구성중 종래의 구성과 동일한 부분은 그 설명을 생략하고 동일부호를 부여하기로 한다.2A to 2D are perspective views of the heat exchanger of the present invention, and the same parts as those of the conventional structure of the present invention will be omitted with the same reference numerals.

이하 본 발명의 요부 구성을 설명하면 다음과 같다.Hereinafter, the main components of the present invention will be described.

본 발명은 다수매의 냉각핀(2)중 가장 좌,우측의 냉각핀 전,후에 상기 냉각핀과 직교되는 방향으로 각각 공기흡입구(4)가 형성된 전면판넬(6)과 공기토출구(5)가 형성된 후면판넬(7)을 일체 형성한 구조이다.According to the present invention, a front panel 6 and an air discharge port 5 each having an air inlet 4 formed in a direction orthogonal to the cooling fins before and after the left and right cooling fins of the plurality of cooling fins 2 are provided. The rear panel 7 formed is integrally formed.

상기 전면판넬(6)에 형성된 공기흡입구(4)의 단면적을 후면판넬(7)에 형성된 공기토출구(5)의 단면적보다 크게 형성하거나, 전면판넬(6)에 형성된 공기흡입구(4)를 후면판넬(7)에 형성된 공기토출구(5)보다 크게 형성함이 바람직 한데, 이는 에어컨을 구성하는 송풍팬의 구동에 의해 전,후면판넬(6)(7) 사이로 흡입된 실내의 공기가 상기 전,후면판넬 사이에서 보다 오랜시간 머무르도록 하여 리턴 밴드(3)부분과 충분한 열교환이 이루어지도록 하기 위함이다.The cross-sectional area of the air intake port 4 formed in the front panel 6 is larger than the cross-sectional area of the air discharge port 5 formed in the rear panel 7, or the air intake port 4 formed in the front panel 6 is formed on the rear panel. It is preferable to form larger than the air discharge port (5) formed in (7), which is the indoor air sucked between the front and rear panels (6) (7) by the driving of the blower fan constituting the air conditioner The reason for this is to allow a longer time between panels to allow sufficient heat exchange with the return band 3.

상기 전면판넬(6)에 형성된 공기흡입구(4)와 후면판넬(7)에 형성된 공기토출구(5)의 형상은 도 2a와 같이 원형의 구멍으로 형성하거나, 도 2b와 같이 세로방향의 장공으로 하거나, 도 2c와 같이 가로방향의 장공으로 하거나, 도 2d와 같이 전,후면판넬(6)(7)을 그물망형태로 할 수 있으나, 공기 흡입구(4)와 공기 토출구(5)의 형상을 필요에 따라 적절한 형태로 설계할 수 있으므로 반드시 이에 한정할 필요는 없다.The air inlet 4 formed in the front panel 6 and the air outlet 5 formed in the rear panel 7 may be formed in a circular hole as shown in FIG. 2c, the front and rear panels 6 and 7 may be meshed as shown in FIG. 2d, but the shape of the air inlet 4 and the air outlet 5 may be Therefore, it can be designed in an appropriate form is not necessarily limited to this.

이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

냉매 파이프(1)의 내부로 차거운 냉매가 흐르고 있는 상태에서는 상기 냉매의 찬 열이 복수매의 냉각핀()을 통해 외부로 발산되는데, 이때 에어컨을 구성하는 송풍팬이 구동하여 실내의 공기를 송풍시켜 주면 이 실내공기는 본체 내부로 흡입되고, 이 흡입된 공기는 냉각핀(2)사이를 통과하는 과정에서 이들과 접촉하여 열교환작용을 일으키므로 결국 공기는 차거워진 다음 계속되는 송풍팬의 회전으로 토출구를 통해 실내로 다시 토출됨에 따라 실내가 냉방되는데, 상기한 동작은 종래의 에어컨과 동일하다.In a state where a cool refrigerant flows into the refrigerant pipe 1, cold heat of the refrigerant is dissipated to the outside through a plurality of cooling fins (), and a blower fan constituting the air conditioner is driven to blow air in the room. In this case, the indoor air is sucked into the main body, and the sucked air is in contact with them in the course of passing between the cooling fins 2, causing heat exchange. Therefore, the air is cooled and then discharged by the continuous rotation of the blower fan. The room is cooled as it is discharged back to the room through, the operation is the same as the conventional air conditioner.

본 발명은 상기한 바와 같은 동작시 일부의 실내공기가 양측의 냉각핀()에 형성된 전면판넬(6)상의 공기흡입구(4)를 통해 흡입되고, 이 흡입되는 공기는 상기 전면판넬(6)과 후면판넬(7)사이의 공간부에서 일시적으로 머무르는데, 이 과정에서 상기 공기는 냉각핀(2)의 외측으로 노출되어 차거운 냉매가 흐르는 리턴 밴드(3)부분과 열교환작용을 하면서 차거워진 다음 후면판넬(7)에 형성된 공기 토출구(5)를 통해 토출되므로 결국 종래의 열교환기에 비해 열교환효율이 더욱 증대됨은 이해 가능하다.According to the present invention, some indoor air is sucked through the air intake port 4 on the front panel 6 formed at the cooling fins on both sides during the operation as described above. Temporarily stays in the space between the rear panel (7). During this process, the air is exposed to the outside of the cooling fin (2) to cool down while exchanging heat with the return band (3) where the coolant flows. Since it is discharged through the air discharge port 5 formed in the panel 7 can be understood that the heat exchange efficiency is further increased compared to the conventional heat exchanger.

이때, 상기 전면판넬(6)에 형성된 공기흡입구(4)의 크기 및 단면적이 후면판넬(7)에 형성된 공기토출구(5)의 크기 및 단면적보다 크게 형성되어 있으므로 전,후면판넬(6)(7) 사이의 공간부로 흡입된 실내의 공기가 전,후면판넬사이에서 오랜 시간동안 머무르면서 리턴 밴드(3)와 더욱 많은 열교환작용을 하여 차거워진 다음 공기토출구(5)를 통해 토출되므로 동일용량의 열교환기인 경우 종래의 에어컨에 비해, 실내의 온도를 보다 빠른 시간내에 설정된 냉각온도로 유지시킬 수 있게 된다.At this time, the size and the cross-sectional area of the air inlet (4) formed in the front panel 6 is larger than the size and cross-sectional area of the air outlet (5) formed in the rear panel (7) front, rear panel (6) (7 The air in the room sucked into the space between them stays between the front and rear panels for a long time, becomes more heat-exchanging with the return band (3), and then is discharged through the air outlet (5). When compared to the conventional air conditioner, it is possible to maintain the temperature of the room at a set cooling temperature within a faster time.

이상에서와 같이 본 발명은 리턴 밴드부분을 열교환면적으로 활용하도록 되어 있어 종래의 열교환기보다 열교환능력을 증대시키게 되므로 에어컨의 냉방능력을 배가시키게 되고, 이에 따라 동일 냉방능력인 경우에 열교환기의 크기를 종래의 열교환기보다 줄일 수 있게 되므로 에어컨의 콤팩트화 실현이 가능해지게 된다.As described above, the present invention is to use the return band portion as a heat exchange area to increase the heat exchange capacity than the conventional heat exchanger, thereby doubling the cooling capacity of the air conditioner, thus the size of the heat exchanger in the case of the same cooling capacity Since it can be reduced than the conventional heat exchanger, it becomes possible to realize the compactness of the air conditioner.
