Description
본 발명은, 열교환기에 관한 것으로서, 보다 상세하게는 핀의 판면을 따라 흐르는 응축수를 원활하게 배출할 수 있는 열교환기에 관한 것이다.The present invention relates to a heat exchanger, and more particularly, to a heat exchanger capable of smoothly discharging condensate flowing along a plate surface of a fin.
열교환기는 에어컨이나 냉장고 또는 냉난방기 등에 증발기 및 응축기로 설치되며, 냉매의 순환 과정에서 열의 방출이나 흡수를 위해 외기와 열교환을 수행한다. 일반적으로 열교환기는, 냉매의 유동을 위한 전열관과 이 전열관에 가로방향으로 소정의 간격을 유지하고 적층되는 복수개의 판상의 핀으로 구성된다.The heat exchanger is installed as an evaporator and a condenser in an air conditioner, a refrigerator, or an air conditioner, and performs heat exchange with outside air for the release or absorption of heat during the circulation of the refrigerant. Generally, a heat exchanger consists of a heat exchanger tube for the flow of a refrigerant | coolant, and a plurality of plate-shaped fins which are laminated | stacked at predetermined intervals in the transverse direction.
도 4는 종래의 열교환기용 핀의 사시도이고, 도 5는 종래의 열교환기의 부분확대단면도이다. 이들 도면에 도시된 바와 같이, 종래의 열교환기(101)는 상호 평행하게 배열된 다수의 냉매유동용 전열관(110)과, 전열관(110)의 길이방향에 가로로 상호 소정의 간격을 두고 평행하게 배열되는 다수의 판상의 핀(120)을 갖는다.4 is a perspective view of a conventional heat exchanger fin, and FIG. 5 is a partially enlarged cross-sectional view of a conventional heat exchanger. As shown in these figures, the conventional heat exchanger 101 is arranged in parallel with a plurality of refrigerant flow transfer tubes 110 arranged in parallel with each other at a predetermined interval horizontally in the longitudinal direction of the heat transfer tube 110. Has a plurality of plate-shaped pins 120.
핀(120)에는, 도 4에 도시된 바와 같이, 핀(120)의 판면을 관통하도록 다수의 관통공(121)들이 형성되어 있으며, 이 관통공(121)에는 전열관(110)들이 통과된다. 핀(120)의 판면에는 관통공(121)의 외주를 둘러싸도록 다수의 슬릿(123)들이 형성되어 있으며, 이 슬릿(123)들은 상호 소정의 간격을 두고 핀(120)의 판면으로부터 절개형성되어 있다. 이들 슬릿(123)들은 판면에서 송풍방향에 가로방향으로 절개된 부위가 송풍방향을 따라 교호적으로 돌출 및 함몰형성되어 있다.4, a plurality of through holes 121 are formed to penetrate the plate surface of the fin 120, and heat pipes 110 pass through the fins 120. A plurality of slits 123 are formed on the plate surface of the fin 120 so as to surround the outer circumference of the through hole 121, and the slits 123 are cut off from the plate surface of the fin 120 at predetermined intervals from each other. have. These slits 123 are alternately protruded and recessed along the blowing direction in a portion cut in the transverse direction in the blowing direction on the plate surface.
각 슬릿(123)은 교호적으로 돌출 및 함몰형성되어 있으므로, 판면을 따라 흐르는 외기의 흐름은 판면에 대해 상하방향으로 굴곡되며 유동하게 된다. 상하방향을 따라 유동하며 흐르는 외기는, 핀(120)의 판면과 돌출 및 함몰된 슬릿(123)을 따라 흐르며 접촉하게 되며, 이에 따라 핀(120)과 송풍되는 외기 사이에 열교환이 이루어지게 된다. 이 때, 핀(120)과 외기 사이에서 열교환이 이루어지게 되면, 송풍되는 외기와 핀(120) 사이에서는 온도차의 발생으로 인하여 응결이 이루어지게 되므로 응축수가 생성된다. 이렇게 생성된 응축수는 핀(120)의 판면을 따라 흘러 외부로 배출된다.Since each slit 123 is alternately protruded and recessed, the flow of outside air flowing along the plate surface is bent and flows upward and downward with respect to the plate surface. The outside air flowing along the up and down direction flows and contacts the plate surface of the fin 120 along the protruding and recessed slits 123, thereby performing heat exchange between the fin 120 and the blown outside air. At this time, when the heat exchange is made between the fin 120 and the outside air, condensation is generated because condensation occurs due to a temperature difference between the blown outside air and the fin 120. The condensate thus generated flows along the plate surface of the fin 120 and is discharged to the outside.
그런데, 이러한 종래의 열교환기에 있어서는, 핀의 판면으로부터 돌출 및 함몰된 슬릿은 일정한 높이를 가지거나, 핀의 하단부로 갈수록 돌출높이가 높아지도록 형성되어 있어 응축수가 외부로 배출되지 않고 슬릿내의 일영역에 고이게 된다. 이렇게 슬릿의 내부에 고이는 되는 응축수는 열교환기의 핀과 외기의 원활한 흐름을 차단하게 되어 열교환효율을 떨어뜨리게 된다는 문제점이 있다.By the way, in such a conventional heat exchanger, the slits protruding and recessed from the plate surface of the fin have a certain height or are formed to have a higher protrusion height toward the lower end of the fin, so that the condensed water is not discharged to the outside and is located in one area within the slit. Going. The condensate that accumulates inside the slit has a problem that the heat exchanger efficiency is lowered by blocking the smooth flow of fins and outside air of the heat exchanger.
따라서, 본 발명의 목적은, 응축수의 배출을 원활하게 할 수 있어 열교환효율을 향상시킬 수 있는 열교환기를 제공하는 것이다.Accordingly, an object of the present invention is to provide a heat exchanger which can smoothly discharge condensate and improve heat exchange efficiency.

상기 목적은, 본 발명에 따라, 상호 평행하게 배열된 다수의 냉매유동용 전열관과, 상기 전열관들의 통과를 위한 관통공들을 가지고 상기 전열관의 길이방향에 가로로 상호 소정의 간격을 두고 평행하게 배열되며 송풍방향에 가로로 형성된 슬릿을 따라 판면으로부터 융기된 슬릿융기부가 형성된 다수의 판상의 핀을 갖는 열교환기에 있어서, 상기 슬릿융기부는 상기 핀의 판면으로부터 돌출형성되며 상기 핀의 판면을 따라 흐르는 응축수가 낙하하는 방향으로 갈수록 돌출높이가 점진적으로 낮아지는 것을 특징으로 하는 열교환기에 의해 달성된다.The object is, according to the present invention, a plurality of refrigerant flow heat exchanger tubes arranged in parallel with each other, the through-holes for the passage of the heat pipes are arranged parallel to each other at a predetermined interval in the transverse direction in the longitudinal direction of the heat pipes and blowing A heat exchanger having a plurality of plate-shaped fins formed with slit ridges raised from a plate along a slit formed transversely in a direction, wherein the slit ridges protrude from the plate plane of the fins, and the condensate flowing along the plate plane of the pins falls. It is achieved by the heat exchanger, characterized in that the height of the projection is gradually lowered toward the direction.
여기서, 상기 핀의 판면으로부터 함몰형성되며 상기 핀의 판면을 따라 흐르는 응축수가 낙하하는 방향으로 갈수록 함몰깊이가 점진적으로 얕아지는 슬릿융기부를 더 포함하는 것이 바람직하다.Here, it is preferable to further include a slit ridge portion which is recessed from the plate surface of the fin and gradually decreases in depth as the condensed water flowing along the plate surface of the fin falls.
이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 열교환기의 외관사시도이며, 도 2는 본 발명에 따른 열교환기용 핀의 사시도이고, 도 3은 본 발명에 따른 핀와 전열관의 조립단면도이다. 이들 도면에 도시된 바와 같이, 본 열교환기(1)는, 상호 평행하게 배열된 다수의 냉매유동용 전열관(10)과, 전열관(10)의 길이방향에 가로로 상호 소정의 간격을 두고 평행하게 배열되는 다수의 판상의 핀(20)을 갖는다.1 is an external perspective view of a heat exchanger, FIG. 2 is a perspective view of a fin for a heat exchanger according to the present invention, and FIG. 3 is an assembled sectional view of a fin and a heat pipe according to the present invention. As shown in these figures, the heat exchanger 1 is arranged in parallel with a plurality of refrigerant flow transfer tubes 10 arranged in parallel with each other at a predetermined interval horizontally in the longitudinal direction of the heat transfer tube 10. It has a plurality of plate-shaped pins 20 that are.
핀(20)에는, 도 2에 도시된 바와 같이, 핀면을 관통하도록 다수의 관통공(21)들이 형성되어 있으며, 이 관통공(21)에는 전열관(10)들이 통과된다. 핀(20)의 판면에는 다수의 슬릿(23)들이 관통공(21)의 외주를 따라 둘러싸며 핀(20)의 판면으로부터 절개되어 돌출 및 함몰형성되어 있다. 각 슬릿(23)들은 소정길이를 가지며, 돌출 및 함몰형성된 슬릿(23)들은 핀(20)의 판면을 따라 흐르는 응축수가 낙하하는 방향으로 갈수록 돌출높이 및 함몰깊이가 낮아지도록 하향경사지게 형성되어 있다. 이들 슬릿(23)들은 판면에서 송풍방향에 가로방향으로 절개된 부위가 송풍방향을 따라 교호적으로 돌출 및 함몰형성되어 있으며, 상호 소정의 간격을 두고 이격되어 있다.As shown in FIG. 2, a plurality of through holes 21 are formed in the fin 20 to penetrate the fin surface, and the heat pipes 10 pass through the through holes 21. On the plate surface of the fin 20, a plurality of slits 23 surrounds the outer circumference of the through hole 21 and is cut out from the plate surface of the pin 20 to protrude and dent. Each of the slits 23 has a predetermined length, and the protruding and recessed slits 23 are formed to be inclined downward so as to lower the protruding height and the depth of depression toward the direction in which the condensate flowing along the plate surface of the fin 20 falls. These slits 23 are protruded and recessed alternately along the blowing direction in portions cut in the transverse direction in the blowing direction from the plate surface, and are spaced apart from each other at predetermined intervals.
이와 같은 구성에 의하여, 외부로부터 송풍되는 공기는 핀(10)의 판면에 돌출 및 함몰형성된 슬릿(23)에 의하여 상하방향으로 유동하며 이동하게 된다. 그리고, 송풍되는 외기가 핀(20)의 판면을 따라 전열관(10)의 둘레를 용이하게 흐르게 되며, 이에 따라 핀(20)과 외기 사이에 열교환이 이루어지게 된다.By such a configuration, the air blown from the outside flows and moves up and down by the slits 23 protruding and recessed in the plate surface of the fin 10. In addition, the outside air to be blown flows easily around the heat pipe 10 along the plate surface of the fin 20, and thus heat exchange is made between the fin 20 and the outside air.
한편, 송풍되는 외기와 열교환기(1)의 핀(20) 사이에서 열교환이 이루어지게 되면 핀(20)과 외기의 온도차에 의하여 기체가 응결되어 응축수가 생기게 된다. 이렇게 생긴 응축수는 열교환기(1)의 핀(20)의 판면을 따라 흐르면서 외부로 배출된다. 이 때, 외부로 배출되는 응축수는, 응축수가 낙하하는 방향으로 갈수록 돌출 높이 및 함몰깊이가 낮아지도록 경사지게 형성된 슬릿(23)을 따라 흐르게 되므로, 슬릿(23)의 내부영역에 고이지 않고 핀(20)의 판면을 따라 열교환기(1)의 하부로 원활하게 배출된다.On the other hand, when heat exchange is performed between the blown outside air and the fins 20 of the heat exchanger 1, the gas is condensed by the temperature difference between the fins 20 and the outside air to produce condensed water. The condensate thus generated flows along the plate surface of the fin 20 of the heat exchanger 1 and is discharged to the outside. At this time, the condensate discharged to the outside flows along the slits 23 formed to be inclined so as to lower the protruding height and the depth of depression toward the direction in which the condensate falls, so that the fin 20 does not accumulate in the inner region of the slit 23. It is smoothly discharged to the lower part of the heat exchanger 1 along the plate surface of the.
이와 같이, 핀의 판면으로부터 돌출형성되며 상기 핀의 판면을 따라 흐르는 응축수가 낙하하는 방향으로 갈수록 돌출높이가 점진적으로 낮아지는 슬릿융기부를 마련함으로써, 핀의 판면을 따라 흐르는 응축수의 배출을 원활하게 할 수 있다.As such, by providing a slit ridge portion which protrudes from the plate surface of the fin and the protrusion height gradually decreases toward the falling direction of the condensate flowing along the plate surface of the fin, it is possible to smoothly discharge the condensate flowing along the plate surface of the fin. Can be.
이상에서 설명한 바와 같이, 본 발명에 따르면, 응축수의 배출을 원활하게 할 수 있어 열교환효율을 향상시킬 수 있는 열교환기가 제공된다.As described above, according to the present invention, a heat exchanger capable of smoothly discharging condensate and improving heat exchange efficiency is provided.
