Description
본 발명은 열교환기에 관한 것으로, 특히 열교환기 표면에 응축수가 퍼져서 막을 형성하거나 서리 생김을 방지하여 열교환 성능을 향상시킬 수 있는 열교환기에 관한 것이다.The present invention relates to a heat exchanger, and more particularly, to a heat exchanger that can improve heat exchange performance by preventing condensed water from spreading on the surface of the heat exchanger to form a film or prevent frost.
일반적으로 열교환기는 온도가 다른 두 개의 유체를 직접 또는 간접으로 접촉시켜 열교환시키는 장치로서, 에어컨이나 냉장고 등 가전제품의 냉동 사이클에 주로 사용된다.In general, the heat exchanger is a device for heat exchange by contacting two fluids of different temperatures directly or indirectly, and is mainly used in a refrigeration cycle of household appliances such as an air conditioner or a refrigerator.
이러한 열교환기는 열교환하는 목적에 따라 핀-튜브(fin-tube) 타입, 쉘-튜브(shell and tube) 타입, 플레이트- 핀 타입 등 다양한 종류가 사용된다.Such heat exchangers are used in various types, such as fin-tube type, shell and tube type, and plate-fin type, depending on the purpose of heat exchange.
그리고, 유체의 흐름에 따라 평행 흐름식 (parallel flow type) 열교환기, 향류식(counter flow type) 열교환기 등으로 분류되고, 열교환하고자 하는 유체의 혼합 여부에 따라 혼합식(mixed type), 비혼합식(unmixed type) 열교환기로 분류된다. 현재 각종 가전제품에서는 그 용도와 용량에 따라 적절한 형태의 열교환기가 사용되고 있다.And, according to the flow of the fluid is classified into a parallel flow (heat exchanger), counter flow (counter flow type) heat exchanger, etc., mixed (mixed type), non-mixed according to the mixing of the fluid to be exchanged It is classified as an unmixed type heat exchanger. Currently, various types of home appliances are using heat exchangers of a suitable type according to their use and capacity.
도 1은 현재 가장 많이 사용되는 핀-튜브 타입의 열교환기를 나타낸 일부 사시도이다.1 is a partial perspective view showing the most commonly used fin-tube type heat exchanger at present.
종래의 열교환기는 일정 간격을 두고 다수개의 핀(102)이 적층되고, 상기 적층된 핀(102)의 직각방향으로 유체가 통과하는 다수개의 튜브(104)가 일정 간격으로 배열되어 구성되고, 대기의 공기가 각 핀(102) 사이의 공간을 통과하면서 튜브에 흐르는 유체의 열교환 작용을 수행한다.A conventional heat exchanger is configured by a plurality of fins 102 stacked at regular intervals, and a plurality of tubes 104 through which fluid passes in a direction perpendicular to the stacked fins 102 are arranged at regular intervals. As air passes through the spaces between the fins 102, it performs a heat exchange action of the fluid flowing in the tube.
이와 같이, 열교환되는 두 유체 중 한쪽이 대기인 경우 열교환 할 때 두 유체 사이의 온도차에 의해 공기 중의 수분이 응결되어 생기는 물방울이나 서리가 열교환기의 표면에 막을 형성하거나 열어 붙게 되어 공기 유동을 방해하고 열저항을 형성하여 열전달을 방해하게 된다.As such, when one of the two heat exchanged fluids is the atmosphere, water droplets or frost formed by condensation of moisture in the air due to the temperature difference between the two fluids during heat exchange forms a film on the surface of the heat exchanger, which causes the air flow to hinder. It forms a thermal resistance that interferes with heat transfer.
상기와 같은 이슬 맺힘 및 서리에 의한 결빙을 해결하기 위해 현재의 열교환기에서는 열교환기에 전열선을 설치하여 일정 시간을 두고 제상운전을 실시하여 열교환기를 가열함으로써, 결빙된 서리를 제거한다.In order to solve the dew condensation and frost as described above, in the current heat exchanger by installing a heating wire in the heat exchanger to perform a defrost operation for a predetermined time to heat the heat exchanger, to remove the frost.
그러나, 상기한 바와 같은 종래의 열교환기는 도 2에 도시된 바와 같이, 열교환시 공기 중의 수분이 응축되는 응축수(106)가 핀(102)의 표면에 맺힐 때 핀(102)의 표면과 응축수(106) 사이의 접촉각(θ1)이 90도 이하로 작기 때문에 응축수(106)의 표면 장력도 작아지게 된다.However, the conventional heat exchanger as described above, as shown in Fig. 2, when the condensate 106 is condensed on the surface of the fin 102, the condensate 106 is condensed water 106, the moisture in the air during heat exchange condensation 106 Since the contact angle [theta] 1 between them is small to 90 degrees or less, the surface tension of the condensate 106 becomes small.
그러므로, 열교환기 표면에 수막이 형성되어 열저항을 발생시키고 열전달을 방해하게 되며, 열교환기의 핀 사이에 물방울이나 서리가 맺힘으로써, 공기의 유동을 방해하여 열교환 효율을 저하시키는 문제점이 있다.Therefore, a water film is formed on the surface of the heat exchanger to generate heat resistance and interfere with heat transfer, and water droplets or frost are formed between the fins of the heat exchanger, thereby preventing the flow of air and reducing heat exchange efficiency.
또한, 서리를 제거하기 위한 제상운전을 실시함에 따른 전력 소모 및 가전 제품 내부의 온도 상승으로 인한 실내 온도유지에 영향을 미치고 냉장고의 경우 저장되는 음식물에 나쁜 영향을 미치는 문제점이 발생된다.In addition, there is a problem that affects the indoor temperature maintenance due to the power consumption and the temperature rise inside the home appliance due to the defrosting operation to remove the frost and adversely affect the food stored in the case of the refrigerator.
또한, 금속인 열교환기의 핀 표면에 수분이 항상 존재하게 되어 부식을 발생시키는 문제점이 있다.In addition, there is a problem in that water is always present on the fin surface of the heat exchanger which is a metal to cause corrosion.
본 발명은 상기한 문제점을 해결하기 위하여 창출된 것으로서, 본 발명의 목적은 열교환기 표면에 마이크로 스케일의 요철구조를 형성하여 열교환기 표면에 맺히는 응축수의 표면장력을 크게 함으로써, 열교환기의 표면에 수막 및 서리 결빙이 발생되지 않도록 하여 공기의 흐름을 원활하게 하고, 열교환 효율을 향상시킬 수 있는 열교환기를 제공하는 데 있다.The present invention has been made to solve the above problems, an object of the present invention is to form a microscale uneven structure on the surface of the heat exchanger to increase the surface tension of the condensate water formed on the surface of the heat exchanger, water film on the surface of the heat exchanger And it is to provide a heat exchanger that can facilitate the flow of air by improving the frost freezing, and improve the heat exchange efficiency.
다른 목적은 이슬 맺힘이나 서리의 결빙을 없애기 위해 실시하는 제상 운전이 불필요하므로 전력 소모를 저감시키고, 가전 제품 내부의 온도 상승으로 인한 나쁜 영향을 방지할 수 있는 열교환기를 제공하는 데 있다.Another object of the present invention is to provide a heat exchanger that can reduce power consumption and prevent a bad effect due to a temperature increase inside a home appliance because defrosting operation to remove dew condensation or frost is unnecessary.

상기한 과제를 실현하기 위한 본 발명에 따른 열교환기는 열교환되는 두 유체 중 한 유체가 대기 중의 공기를 사용하는 열교환기에 있어서, 상기 열교환기의 표면에 열교환시 발생되는 응축수와 열교환기 표면 사이의 접촉각을 크게 하여 응축수의 표면장력을 증대시키는 표면장력 증대수단이 형성되어짐을 특징으로 한다.In the heat exchanger according to the present invention for realizing the above object, one of the two fluids to be heat exchanged uses air in the air, the contact angle between the condensate generated during the heat exchange and the surface of the heat exchanger on the surface of the heat exchanger It is characterized in that the surface tension increasing means for increasing the surface tension of the condensate is formed.
이하, 첨부된 도면을 참조하여 본 발명의 일 실시예를 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
도 3은 본 발명에 따른 열교환기의 일부 사시도이고, 도 4는 본 발명의 일 실시예에 따른 열교환기의 확대 단면도이다.3 is a partial perspective view of a heat exchanger according to the present invention, Figure 4 is an enlarged cross-sectional view of the heat exchanger according to an embodiment of the present invention.
도 3 및 도 4에 따르면 본 발명의 열교환기는 핀-튜브 타입으로, 유체가 통과할 수 있는 일정 간격을 두고 다수개로 적층되는 핀(2)과, 상기 핀(2) 사이에 관통되어 일정 간격으로 배열되고 내부에 유체가 흐르는 튜브(4)와, 상기 핀(2)의 표면 또는 튜브(4)의 표면에 형성되어 공기 중의 수분이 응축되어 발생되는 응축수의 표면장력을 증대시키는 표면장력 증대수단 등으로 구성된다.According to FIGS. 3 and 4, the heat exchanger of the present invention is a fin-tube type, in which a plurality of fins 2 are stacked at regular intervals through which a fluid can pass, and penetrated between the fins 2 at regular intervals. Surface tension increasing means arranged on the surface of the tube 4 and the fluid flowing therein and the surface of the fin 2 or the surface of the tube 4 to increase the surface tension of condensate generated by condensation of moisture in the air. It consists of.
이러한, 열교환기는 핀(2)과 핀(2) 사이의 공간으로 대기의 공기를 불어 넣으면, 튜브(4) 내부에 흐르는 유체와의 사이에서 열교환이 이루어진다. 이때, 두 유체 즉, 튜브(4) 내부에 흐르는 유체와 대기 중 공기 사이의 온도차에 의해 대기 중의 수분이 응축되는 응축수가 핀이나 튜브의 표면에 맺히게 된다.Such a heat exchanger blows atmospheric air into the space between the fins 2 and 2, and heat exchange occurs between the fluid flowing in the tube 4. At this time, the condensed water condensed with moisture in the air is formed on the surface of the fin or the tube by the temperature difference between the two fluids, that is, the fluid flowing inside the tube 4 and the air in the air.
상기 표면장력 증대수단은 핀(2)의 표면에 맺힌 응축수(10)의 표면 장력을 증대시켜 쉽게 분리될 수 있도록 하는 것으로, 핀(2)의 표면에 폴리머 구멍 가공으로 미세한 마이크로 스케일(micro-scale)의 요철 구조를 형성한 것이다. 여기에서, 마이크로 스케일 가공을 실시하면 약 25㎛ 정도의 미세 구멍이 형성되고, 이때, 핀(2)의 표면에는 미소돌기(8)가 돌출된다.The surface tension increasing means increases the surface tension of the condensed water 10 formed on the surface of the fin 2 so that the surface tension increasing means can be easily separated, and fine micro-scale by polymer hole processing on the surface of the fin 2. ) Is a concave-convex structure. Here, when microscale processing is carried out, a fine hole of about 25 μm is formed, and at this time, the micro-projections 8 protrude from the surface of the pin 2.
도 5에 도시된 바와 같이, 응축수(10)는 미소돌기(8)의 끝부분에 맺히게 되고, 이때 미소돌기(8)에 의해 응축수(10)의 접촉각(θ2)이 크게 되어 결과적으로 응축수(10)의 표면장력을 커지도록 도와 응축수(10)가 핀(2)의 표면에서 쉽게 분리될 수 있도록 한다.As shown in FIG. 5, the condensate 10 is formed at the end of the microprojection 8, and at this time, the contact angle θ2 of the condensate 10 is increased by the microprojections 8, resulting in condensate 10. ) To increase the surface tension of the condensate (10) can be easily separated from the surface of the fin (2).
여기에서, 상기 접촉각(θ2)은 액체와 기체의 표면이 고체면과 이루는 각도로서, 표면장력이 큰 액체일 경우 접촉각은 커지게 된다. 즉, 표면장력이 작아서 접촉각이 90°보다 작을 경우에는 젖음(wetting)이라 하고, 접촉각이 90°보다 큰경우에는 비젖음(nonwetting) 이라 하며 접촉각이 큰 경우를 말한다.Here, the contact angle θ2 is an angle at which the surfaces of the liquid and the gas form the solid surface, and the contact angle becomes large when the surface tension is large. In other words, when the contact angle is smaller than 90 ° because of the small surface tension, wetting is called. When the contact angle is larger than 90 °, it is called nonwetting and the contact angle is large.
이와 같이, 핀(2)의 표면에 형성되는 미소돌기(8)에 응축수(10)가 맺히게 되면 미소돌기(8)가 응축수(10)의 접촉각(θ2)을 크게 하여 비젖음(nonwetting) 상태로 함으로써, 응축수(10)가 핀(2)의 표면에 수막 및 서리 응결을 방지하여 용이하게 분리된다.As such, when the condensed water 10 forms on the micro-projections 8 formed on the surface of the fin 2, the micro-projections 8 increase the contact angle θ 2 of the condensed water 10 to a nonwetting state. As a result, the condensate 10 is easily separated by preventing water film and frost condensation on the surface of the fin 2.
상기에서, 핀(2)의 표면뿐만 아니라 튜브(4)의 외주면에도 역시 동일한 미소돌기(8)를 형성하여 동일한 효과를 얻을 수 있다.In the above, not only the surface of the fin 2 but also the outer circumferential surface of the tube 4 can also form the same microprojections 8 to obtain the same effect.
도 6은 본 발명의 제2실시예에 따른 표면장력 증대수단을 나타낸 사시도이고, 도 7은 본 발명의 제2실시예에 따른 응축수의 맺힘 상태를 나타낸 사용 상태도이다.6 is a perspective view showing the surface tension increasing means according to a second embodiment of the present invention, Figure 7 is a state diagram showing the condensed water condensation state according to a second embodiment of the present invention.
제2실시예에 따른 열교환기의 표면장력 증대수단은 핀(26) 또는 튜브의 표면에 마이크로 스케일 가공을 실시하여 서로 직교되는 막대 타입 돌기(20)를 형성하여 이루어진다.The surface tension increasing means of the heat exchanger according to the second embodiment is formed by forming a rod-type protrusion 20 orthogonal to each other by performing micro-scale processing on the surface of the fin 26 or the tube.
즉, 도 7에 도시된 바와 같이, 일정 각도로 서로 직교되는 다수의 막대 타입 돌기(20)를 핀(26) 또는 튜브의 표면에 형성시켜 응축수(22)가 직접 핀(26)의 표면에 접촉되지 않고 막대 타입 돌기(20)의 끝부분에 맺히게 되고, 이때, 그 접촉각(θ3)이 커지게 되므로 응축수(22)의 표면장력이 증대되어 핀(26)의 표면에서 용이하게 분리된다.That is, as shown in FIG. 7, a plurality of rod-type protrusions 20 orthogonal to each other at an angle are formed on the surface of the fin 26 or the tube so that the condensate 22 directly contacts the surface of the fin 26. It is not formed at the end of the rod-type protrusion 20, at this time, the contact angle (θ3) is increased, so that the surface tension of the condensate 22 is increased to be easily separated from the surface of the pin 26.
따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 열교환기는 열교환기의 표면에 마이크로 스케일 가공을 실시하여 미소돌기를 형성함으로써, 응축수와 열교환기 표면 사이의 접촉각을 크게 하여 그 표면장력을 증대시켜 보다 쉽게 응축수가 분리될 수 있도록 한다.Therefore, the heat exchanger according to the present invention constructed and operated as described above forms a micro-projection by performing micro-scale processing on the surface of the heat exchanger, thereby increasing the contact tension between the condensate and the surface of the heat exchanger, thereby increasing the surface tension. Allow condensate to separate easily.
그리고, 이와 같이 열효관기의 표면에 수막 및 서리 결빙을 방지함으로써, 공기 유동을 원활하게 하고 열전달 효율을 증대시킬 수 있다.In this way, by preventing the water film and frost freezing on the surface of the thermally effective tube, it is possible to smooth the air flow and increase the heat transfer efficiency.
또한, 응축수가 미소돌기의 끝부분에 맺히게 되므로 열교환기의 표면에 직접 접촉되기 않기 때문에 열교환기의 부식을 방지할 수 있다.In addition, since the condensed water is formed at the end of the micro-projection, it is possible to prevent corrosion of the heat exchanger because it is not directly in contact with the surface of the heat exchanger.
또한, 서리 결빙 및 이슬 맺힘을 방지하기 위한 별도의 제상 운전 등이 불필요하므로 소비전력을 줄이고, 제품 전체의 구조를 단순화함과 아울러 제상 운전으로 인한 제품 내부의 온도 증가 및 열손실을 방지할 수 있다.In addition, since there is no need for a separate defrosting operation to prevent frost freezing and dew condensation, power consumption can be reduced, the structure of the whole product can be simplified, and the temperature increase and heat loss inside the product due to the defrosting operation can be prevented. .
