Description

열교환기 및 그 제조방법Heat exchanger and its manufacturing method

본 발명은, 열교환기 및 그 제조방법에 관한 것으로서, 보다 상세하게는 응축수가 핀의 관통공의 외주연부에 고이는 것을 방지하여 공기의 순환을 원활하게 이룰 수 있는 열교환기 및 그 제조방법에 관한 것이다.The present invention relates to a heat exchanger and a method for manufacturing the same, and more particularly, to a heat exchanger and a method for manufacturing the same to prevent condensed water from accumulating on the outer periphery of the through hole of the fin and to smoothly circulate air. .

열교환기는 에어컨이나 냉장고 또는 냉난방기 등에 증발기 및 응축기로 설치되며, 냉매의 순환 과정에서 열의 방출이나 흡수를 위해 외기와 열교환을 수행한다. 응축기는, 압축기로부터 유입된 고온고압의 기체냉매로부터 외부로 열을 방출하여 액화시키며, 증발기는 액체상태의 냉매가 증발할 때의 흡수열로 외부로부터 송풍되는 공기를 냉각하여 냉기를 형성한다. 이러한 열교환기는, 일반적으로, 냉매가 흐르는 전열관과 이 전열관에 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. The condenser releases heat from the high-temperature, high-pressure gas refrigerant introduced from the compressor to the outside to liquefy, and the evaporator cools the air blown from the outside with absorption heat when the liquid refrigerant evaporates to form cold air. Such a heat exchanger generally consists of a heat exchanger tube through which a refrigerant flows, and a plurality of plate-like fins which are stacked at a predetermined interval in the heat transfer tube.

도 3은 종래의 열교환기에 따른 부분확대단면도이다. 이 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.3 is a partially enlarged cross-sectional view of a conventional heat exchanger. As shown in this figure, the conventional heat exchanger 101 is arranged in parallel with a plurality of refrigerant flow transfer tubes 110 and parallel to each other in the longitudinal direction of the heat transfer tube 110 arranged in parallel to each other in the longitudinal direction. Has a plurality of plate-shaped pins 120.

핀(120)의 판면에는 전열관(110)들의 통과를 위한 다수의 관통공(121)들이 형성되어 있으며, 핀(120)의 판면에는 핀(120)과 핀(120)의 사이에 맺히는 응축수를 효율적으로 제거하기 위하여 친수재(125)를 도포한다. 친수재(125)는 물에 대한 친화력이 강한 친수도료로 소정의 계면활성제가 함유되어 있으며, 물을 넓게 퍼지게 한다.The plate surface of the fin 120 is formed with a plurality of through-holes 121 for the passage of the heat transfer pipes 110, the plate surface of the fin 120 efficiently condensed water formed between the fin 120 and the fin 120 In order to remove the hydrophilic material 125 is applied. The hydrophilic material 125 is a hydrophilic paint having a strong affinity for water, and contains a predetermined surfactant, and spreads water widely.

따라서, 친수재(125)를 도포한 핀(120)의 판면에서는, 응축수가 핀(120)의 판면에 맺히게 되는 경우 친수재(125)에 의하여 핀(120)의 표면에서 당기는 인력이 커지게 되어 핀(120)의 판면에 넓게 퍼지게 된다. 이로 인하여, 핀(120)의 판면에서는 응축수가 모아지지 않고 넓게 퍼지게 되므로 응축수가 용이하게 외부로 배출된다.Therefore, in the plate surface of the fin 120 to which the hydrophilic material 125 is applied, the attraction force pulled from the surface of the fin 120 by the hydrophilic material 125 becomes large when the condensate forms on the plate surface of the fin 120. It spreads widely over the plate surface of the pin 120. For this reason, the condensate is easily discharged to the outside because the condensate is spread in the plate surface of the fin 120 without being collected.

한편, 핀(120)의 관통공(121)의 외주연부에서는, 도포된 친수재(125)에 의하여 응축수가 핀(120)의 하단부로 떨어지지 못하고 핀(120)과 핀(120) 사이에 넓게 퍼지게 되면서 응축수가 고이는 영역이 생기게 된다.On the other hand, in the outer periphery of the through-hole 121 of the fin 120, the condensed water does not fall to the lower end of the fin 120 by the applied hydrophilic material 125 to spread widely between the fin 120 and the fin 120 As a result, condensate will accumulate.

따라서, 이러한 종래의 열교환기에 있어서는, 핀의 관통공의 외주연부에 도포된 친수재에 의하여 고이는 응축수에 의하여 송풍되는 공기의 흐름을 원활하게 이루게 할 수 없어 공기의 통풍저항을 증가시키는 것은 물론이고 이로 인하여, 열전달이 효과적으로 이루어지지 않아 열전달효율을 떨어뜨린다는 문제점이 있다.Therefore, in such a conventional heat exchanger, due to the hydrophilic material applied to the outer periphery of the through hole of the fin, it is not possible to smoothly flow the air blown by the condensed water, which of course increases the ventilation resistance of the air. Due to this, there is a problem that the heat transfer is not made effectively, thereby reducing the heat transfer efficiency.

따라서, 본 발명의 목적은, 응축수가 핀의 관통공의 외주연부에 고이는 것을 방지하여 송풍되는 공기를 원활하게 순환시킬 수 있으며 이로 인해, 열전달효율을 향상시킬 수 있는 열교환기를 제공하는 것이다.Accordingly, an object of the present invention is to provide a heat exchanger that can prevent the condensed water from accumulating in the outer periphery of the through hole of the fin to smoothly circulate the air to be blown, thereby improving the heat transfer efficiency.

여기서, 상기 핀의 관통공의 외주연부에 비친수영역이 존재하는 것이 바람직하다.Here, it is preferable that a non-hydrophilic region exists at the outer peripheral edge of the through hole of the pin.

한편, 본 발명의 다른 목적에 따르며, 상호 평행하게 배열된 다수의 냉매유동용 전열관과, 상기 전열관들의 통과를 위한 관통공들을 가진 상기 전열관의 길이방향에 가로로 상호 소정의 간격을 두고 평행하게 배열되는 다수의 판상의 핀을 갖는 열교환기의 제조방법에 있어서, 상기 핀의 관통공주위영역을 제외한 나머지 판면에 친수재를 도포하는 단계와; 상기 관통공에 상기 전열관을 통과시키는 단계를 포함하는 것을 특징으로 하는 열교환기의 제조방법에 의해 달성된다.On the other hand, according to another object of the present invention, a plurality of refrigerant flow transfer tubes arranged in parallel with each other, and arranged parallel to each other at a predetermined interval horizontally in the longitudinal direction of the heat transfer tube having through holes for the passage of the heat transfer tubes. A method of manufacturing a heat exchanger having a plurality of plate-shaped fins, the method comprising: applying a hydrophilic material to the remaining plate surface except the through-hole periphery region of the fin; It is achieved by the method of manufacturing a heat exchanger comprising the step of passing the heat pipe through the through hole.

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 사시도이며, 도 2는 도 1의 Ⅱ-Ⅱ선에 따른 열교환기의 부분확대단면도이다. 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 a perspective view of a heat exchanger, and FIG. 2 is a partially enlarged cross-sectional view of the heat exchanger according to line II-II of FIG. 1. 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)의 판면에는 전열관(10)들의 통과를 위한 다수의 관통공(21)들이 형성되어 있으며, 핀(20)의 판면에는 핀(20)과 핀(20)의 사이에 맺히는 응축수를 효율적으로 제거하기 위하여 친수재(25)를 도포한다. 이 때, 친수재(25)는 핀(20)의 관통공(21)의 외주연부를 제외한 나머지 판면에 도포되므로, 핀(20)의 관통공(21)의 외주연부는 친수재(25)가 도포되지 않는 비친수영역(27)이 형성된다.The plate surface of the fin 20 is formed with a plurality of through-holes 21 for the passage of the heat transfer tubes 10, the plate surface of the fin 20 efficiently condensed water formed between the fin 20 and the fin 20 In order to remove the hydrophilic material 25 is applied. At this time, the hydrophilic material 25 is applied to the remaining plate surface except the outer peripheral edge of the through hole 21 of the pin 20, the outer peripheral edge of the through hole 21 of the pin 20 is a hydrophilic material 25 A non-hydrophilic region 27 that is not coated is formed.

이 때, 친수재(25)는 물에 대한 친화력이 강한 친수도료로 소정의 계면활성제가 함유되어 있으며, 물과의 친화력이 강하여 물을 핀(20)의 판면에 넓게 퍼지게 하는 역할을 한다.At this time, the hydrophilic material 25 is a hydrophilic paint having a strong affinity for water, and contains a predetermined surfactant, and has a strong affinity with water to play a role of spreading water widely on the plate surface of the fin 20.

이와 같은 구성에 의하여, 친수재(25)가 도포된 핀(20)의 판면에서는 물에 대한 친화력이 커지기 때문에 핀(20)의 판면을 따라 흐르는 응축수가 핀의 하단영역으로 흘러 외부로 배출된다. 그리고, 핀(20)의 관통공(21)의 외주연부의 비친수영역(27)에서는, 친수재(25)가 도포되어 있지 않으므로, 응축수를 당기는 인력이 핀(20)의 판면에서의 응축수를 당기는 인력에 비해 상대적으로 작게 작용하게 된다. 이로 인해, 핀(20)의 관통공(21)의 외주연부에 맺히는 응축수가 핀(20)의 판면에 고이지 않고 핀(20)의 하단부를 통하여 외부로 배출되는 것이 용이하다.By such a configuration, since the affinity for water is increased in the plate surface of the fin 20 to which the hydrophilic material 25 is applied, condensate flowing along the plate surface of the fin 20 flows to the lower region of the fin and is discharged to the outside. In the non-hydrophilic region 27 of the outer circumferential edge of the through hole 21 of the pin 20, since the hydrophilic material 25 is not coated, the attraction force for pulling the condensed water causes The pulling force is relatively small compared to the manpower. For this reason, it is easy for the condensed water which is formed in the outer periphery of the through-hole 21 of the fin 20 to discharge to the outside through the lower end of the fin 20, without accumulating on the plate surface of the fin 20.

이와 같이, 핀의 관통공의 주위영역을 제외한 나머지 판면에 친수재가 도포되어 있음으로써, 응축수가 핀의 관통공의 외주연부에 넓게 퍼지면서 고이는 현상을 방지할 수 있다.In this way, the hydrophilic material is applied to the remaining plate surface except the peripheral region of the through-hole of the pin, so that condensate can spread to the outer periphery of the through-hole of the pin and prevent the swelling phenomenon.

이상에서 설명한 바와 같이, 본 발명에 따르면, 응축수가 핀의 관통공의 외주연부에 고이는 것을 방지하여 공기의 순환을 원활하게 이룰 수 있어, 열전달효율을 향상시킬 수 있는 열교환기 및 그 제조방법이 제공된다.As described above, the present invention provides a heat exchanger and a method of manufacturing the same, which prevents condensed water from accumulating on the outer periphery of the through-hole of the fin and achieves a smooth circulation of air, thereby improving heat transfer efficiency. do.
