It relates to a heat exchanger for an outdoor unit of a heat pump that can be moved to.

일반적으로 히트펌프는 에어컨의 냉각 사이클(cooling cycle)에서 냉매의 흐름을 역전환시킴으로써 냉방과 난방을 겸할 수 있는 공기 조절장치로 이용되고 있으며, 이러한 히트펌프는 계절에 구애받지 않고 사용할 수 있는 장점에 따라 점차적으로 그 사용영역이 확대되고 있다.In general, the heat pump is used as an air conditioner that can both cool and heat by reversing the flow of refrigerant in the cooling cycle of the air conditioner, and the heat pump can be used regardless of the season. Therefore, the use area is gradually expanding.

이러한 히트펌프는 통상적으로 외부와 열교환을 위해 열교환기를 설치하고 있다. 종래 실외기용 열교환기는 내부에 냉매가 흐르는 다수의 냉매관과, 냉매관과 접촉되도록 설치되어 외부와 열교환을 하는 다수의 방열핀을 포함하여 구성된다.These heat pumps are usually provided with a heat exchanger for heat exchange with the outside. The conventional outdoor unit heat exchanger is configured to include a plurality of refrigerant pipes through which refrigerant flows and a plurality of heat dissipation fins installed to be in contact with the refrigerant pipe to exchange heat with the outside.

그런데, 난방사이클 과정에서 실외 온도의 급격한 하강에 의해 실외에 설치된 실외기용 열교환기의 방열핀 상에 액적(water droplet)이 형성되고, 상기 액적의 부피가 점점 커지면서 서리가 맺히는 착상(着想)현상이 발생되어 열교환효율이 급격히 낮아지는 문제점이 있었다. However, during the heating cycle, a rapid drop in the outdoor temperature causes water droplets to form on the heat dissipation fins of the heat exchanger for the outdoor unit installed outdoors. There was a problem that the heat exchange efficiency is sharply lowered.

이에 따라, 착상현상을 방지하는 수단으로서 방열핀의 표면에 자기발열이 가능한 발열소자를 부착하고, 외부전원을 인가하여 착상을 방지하는 방법 등이 제안되었다.Accordingly, as a means of preventing the phenomenon of phenomena, a method of attaching a heat generating element capable of self-heating to the surface of the heat radiating fin and applying an external power source to prevent frosting has been proposed.

또한, 열교환기의 방열핀 표면에 액적이 일 방향으로 이동함으로써 착상현상을 예방하여 열교환기의 효율저하를 방지할 수 있는 히트펌프의 실외기용 열교환기를 제공함에 있다.In addition, it is to provide a heat exchanger for the outdoor unit of the heat pump that can prevent the fall of the efficiency of the heat exchanger by preventing the droplets to move in one direction on the surface of the heat radiating fin of the heat exchanger.

또한, 종래와 비교하여 착상현상을 방지하는 별도의 발열수단 등을 구비하지 않아도 됨으로써 제조비용을 절감할 수 있는 히트펌프의 실외기용 열교환기를 제공함에 있다.In addition, the present invention provides a heat pump heat exchanger for an outdoor unit of a heat pump that can reduce manufacturing costs by not having to provide a separate heat generating means for preventing an frosting phenomenon as compared with the conventional art.

도 1 및 도 2를 참조하면, 본 발명의 제1실시예에 따른 히트펌프의 실외기용 열교환기(1)는 냉매관(10), 복수의 방열핀(20) 및 전원유닛(30)을 포함하여 구성될 수 있다.1 and 2, the heat exchanger 1 for the outdoor unit of the heat pump according to the first embodiment of the present invention includes a refrigerant pipe 10, a plurality of heat dissipation fins 20, and a power supply unit 30. Can be configured.

상기 냉매관(10)은 내부에 냉매가 흐르도록 마련되어 상호 연결되도록 다수 배열 설치된다.The refrigerant pipe 10 is provided with a plurality of arrays so that the refrigerant flows therein and connected to each other.

상기 복수의 방열핀(20)은 판상의 통전가능한 도전체로 마련되어 냉매관(10)의 법선방향으로 배치되며, 상호 이격되도록 배열되되 실질적으로 균일한 간격으로 평행하게 배열된다.The plurality of heat dissipation fins 20 are provided in a plate-like conducting conductor and are arranged in the normal direction of the refrigerant pipe 10 and are arranged to be spaced apart from each other, but are arranged in parallel at substantially uniform intervals.

여기서, 상기 복수의 방열핀(20)은 적어도 제1방열핀(21)과 제2방열핀(22)을 포함하여 구성될 수 있다. 이때, 제1방열핀(21)은 복수의 방열핀 중 어느 하나일 수 있다.The plurality of heat dissipation fins 20 may include at least a first heat dissipation fin 21 and a second heat dissipation fin 22. In this case, the first heat dissipation fin 21 may be any one of a plurality of heat dissipation fins.

상기 제2방열핀(22)은 제1방열핀(21)과 이웃하는 방열핀으로서, 후술할 전원유닛(30)의 전압이 인가되는 통전부(221)와, 통전부(221)를 복수 개로 구획하는 절연부(222)로 구성될 수 있다.The second heat dissipation fin 22 is a heat dissipation fin adjacent to the first heat dissipation fin 21. The second heat dissipation fin 22 is divided into a plurality of conductive portions 221 to which a voltage of the power supply unit 30 to be described below is applied, and a plurality of conductive portions 221. It may be composed of a portion 222.

절연부(22)는 통전부(221)와 비교하여 길이방향으로 비교적 좁은 폭으로 형성되며, 일정 간격으로 설치됨으로써 복수 개의 통전부(221)를 구획함으로써 각 통전부(21)가 상호 절연될 수 있다.The insulator 22 is formed to have a relatively narrow width in the longitudinal direction compared to the conducting unit 221, and is installed at a predetermined interval so that the plurality of conducting units 21 may be insulated from each other by partitioning the plurality of conducting units 221. have.

상기 전원유닛(30)은 전원(31)을 포함하여 제1방열핀(21)과 제2방열핀(20)의 각 통전부(221)와 연결되어 소정의 제어부에 의해 제어되어 각 방열핀에 전압을 인가하도록 설치된다.The power supply unit 30 is connected to each of the current-carrying portions 221 of the first heat dissipation fin 21 and the second heat dissipation fin 20 including the power 31 and controlled by a predetermined control unit to apply voltage to each heat dissipation fin. To be installed.

이때, 제2방열핀(20)의 각 통전부(221) 사이에는 전압인가 온오프(on/off) 가 가능한 스위치(32)가 설치되어, 각 통전부(221)에 전압을 선택적으로 인가할 수 있다.At this time, a switch 32 capable of applying voltage on / off is provided between each current-carrying portion 221 of the second heat dissipation fin 20 to selectively apply voltage to each current-carrying portion 221. have.

다음으로, 상기된 본 발명의 제1실시예에 따른 작동상태를 설명한다. 도 3과 도 4는 도 2의 작동상태도이다.Next, an operation state according to the first embodiment of the present invention described above will be described. 3 and 4 is an operating state diagram of FIG.

여기서, 제1방열핀(10)에는 일정 전압이 연속적으로 인가되고, 제2방열핀(20)의 각 통전부는 일정 전압이 일정 주기를 가지고 하향으로 순차적으로 반복하여 인가되도록 제어된다고 가정한다.Here, it is assumed that a predetermined voltage is continuously applied to the first heat sink fins 10, and each energization part of the second heat sink fins 20 is controlled so that a predetermined voltage is repeatedly applied sequentially and downwardly with a predetermined period.

도 3을 참조하면, 제1방열핀(10)과 제2방열핀(20) 중 제1통전부(2210)에 동시에 접촉하는 액적(water droplet)이 형성시, 제1방열핀(10)에는 일정 전압이 연속적으로 인가되어 있고, 제2방열핀(20) 중 제2통전부(2211)에 전압이 인가되면 제2통전부(2211)의 표면으로 액적(A)이 이동하게 된다.Referring to FIG. 3, when water droplets contacting the first conducting portion 2210 are formed simultaneously among the first heat dissipation fin 10 and the second heat dissipation fin 20, the first heat dissipation fin 10 has a constant voltage. When continuously applied and a voltage is applied to the second conducting portion 2211 of the second heat radiating fin 20, the droplet A moves to the surface of the second conducting portion 2211.

이는, 전기습윤(electorwetting) 원리에 기반한 것인데, 전기습윤이란 도 5에 도시된 바와 같이, 대향된 두 유전체의 사이에 두 유전체와 맞닿는 액적이 형성시 두 유전체에 전압을 인가하면 액적의 표면접촉각이 작아져(θ1->θ2) 유전체 면 상으로 넓게 퍼지는 현상을 말한다.This is based on the principle of electorwetting. As shown in FIG. 5, when the droplets contacting the two dielectrics are formed between two opposed dielectrics, the surface contact angle of the droplets is reduced. It becomes smaller (θ 1- > θ 2 ) and spreads widely over the dielectric plane.

즉, 제2통전부(2211)에 전압이 인가되면, 액적(A)의 표면접촉각이 작아지면서 제2통전부(2211)의 내측방향으로 넓게 퍼지면서 제2통전부(2211)의 표면상에 기존에 형성되어 있는 다른 액적(A)과 합쳐지면서 부피는 커지면서 넓게 퍼지게 된다.That is, when a voltage is applied to the second conducting portion 2211, the surface contact angle of the droplet A decreases and spreads widely in the inward direction of the second conducting portion 2211 on the surface of the second conducting portion 2211. As it is combined with other droplets (A) previously formed, the volume becomes wider and wider.

아울러, 제1통전부(2210) 상에 존재하는 액적(A)의 나머지 부분은 액적(A)의 표면장력에 의해 제2통전부(2211) 상으로 이동을 하게 된다.In addition, the remaining portion of the droplet (A) present on the first conducting portion 2210 is moved on the second conducting portion 2211 by the surface tension of the droplet (A).

그리고, 도 4를 참조하면, 제2통전부(2211)에 이어 제3통전부(2212)에 전압을 인가시에(이때에는 제2통전부(2211)의 전압은 오프(off)로 변환됨) 제3통전부(2212)와 접촉된 액적(A)의 표면접촉각은 작아지면서 상기된 제2통전부(2211)의 전압인가시와 같은 현상이 발생한다.4, when a voltage is applied to the third conducting unit 2212 following the second conducting unit 2211 (in this case, the voltage of the second conducting unit 2211 is converted to off). The surface contact angle of the droplet A in contact with the third conducting portion 2212 decreases, and the same phenomenon occurs when the voltage applied to the second conducting portion 2211 is applied.

즉, 제1통전부(2210)으로부터 제2통전부(2211), 제3통전부(2212)를 거쳐 마지막 통전부까지 전원을 순차적으로 인가하면 각 통전부의 표면에 형성된 액적(A)을 하향으로 이동시킬 수 있다.That is, when power is sequentially applied from the first conducting portion 2210 to the last conducting portion through the second conducting portion 2211 and the third conducting portion 2212, the droplet A formed on the surface of each conducting portion is downward. Can be moved to

결과적으로, 거시적으로 봤을 때는 제1방열핀(10)과 제2방열핀(20)의 표면은 마치 친수성으로 표면처리된 것과 같아져 표면에 형성된 액적(A)은 표면을 따라 흘러내리는 것과 같이 나타날 수 있다.As a result, when viewed macroscopically, the surfaces of the first heat sink fins 10 and the second heat sink fins 20 are as if they were hydrophilic surface treated, so that the droplets A formed on the surface may appear to flow along the surface. .

이와 같은 원리로 히트펌프의 실외기용 열교환기가 작동함으로써 난방사이클 중에도 방열핀의 표면은 액적(A)이 방열핀의 사이 간격과 대응되는 크기로 형성되기만 하면 하향으로 낙하하게 됨으로써 방열핀 표면에서의 착상현상이 예방되어 열교환기의 효율저하를 방지할 수 있다.
In this way, the heat pump heat exchanger for the outdoor unit of the heat pump operates so that even during the heating cycle, the surface of the heat sink fin falls downward as long as the droplets A have a size corresponding to the spacing between the heat sink fins, thereby preventing frost phenomenon on the surface of the heat sink fins. Therefore, the efficiency of the heat exchanger can be prevented from being lowered.

다음으로, 본 발명의 제2실시예에 대해 설명한다. 본 발명의 제2실시예는 제1실시예와 비교하여 제2방열핀의 구조가 부분적으로 변경된다.Next, a second embodiment of the present invention will be described. In the second embodiment of the present invention, the structure of the second heat dissipation fin is partially changed in comparison with the first embodiment.

도 6은 본 발명의 제2실시예에 따른 히트펌프의 실외기용 열교환기의 개략도이다. 도 6을 참조하면, 본 발명의 제2실시예에서는 제2방열핀(22A)의 복수의 통전부로 구획되도록 각 통전부가 상호 분리형성된다. 이외 다른 구성들은 제1실시예와 동일하므로 상세한 설명은 생략한다.6 is a schematic diagram of a heat exchanger for an outdoor unit of a heat pump according to a second embodiment of the present invention. Referring to FIG. 6, in the second embodiment of the present invention, the respective conducting portions are separated from each other so as to be partitioned into a plurality of conducting portions of the second heat radiating fin 22A. Since other configurations are the same as those of the first embodiment, detailed description thereof will be omitted.

이와 같이 설치된 상태에서 제1방열핀(21)에 전압을 인가하고 동시에 제2방열핀(22A)의 각 통전부에 순차적으로 일정 주기를 가지고 전압을 인가하면 제1실시예에서와 같은 방법으로 표면에 형성된 액적(A)이 이동될 수 있다.When the voltage is applied to the first heat radiation fin 21 in the installed state and the voltage is sequentially applied to the energization portions of the second heat radiation fin 22A in sequence, the surface is formed on the surface in the same manner as in the first embodiment. Droplet A may be moved.
