Description

에어콘용 실외열교환기의 방열구조 { A Radition Structure Of Outside Heat Exchanger For Air-Conditioner }A Radiation Structure Of Outside Heat Exchanger For Air-Conditioner}

본 발명은 에어콘의 실외열교환기에 관한 것으로, 특히, 방열핀에 상,하로 교번적으로 다수 절곡된 절곡슬릿부를 형성하여 공기와 접촉시에 대류현상을 향상하여 열교환 효율을 증대하도록 하는 에어콘용 실외열교환기의 방열구조에 관한 것이다.The present invention relates to an outdoor heat exchanger for an air conditioner, and in particular, an outdoor heat exchanger for increasing the heat exchange efficiency by improving the convection phenomenon when contacting air by forming a bent slit part alternately up and down on the heat radiating fin. It relates to a heat radiation structure of.

일반적으로, 에어콘은 냉방기의 일종으로서, 모터가 구동되는 응축기로 냉매를 고압으로 압축하여 액화시키고, 이 고압으로 응축된 냉매를 관의 직경이 작은 로 이동시키면서 증발기에서 냉매를 순간적으로 기화시켜 증발시키므로 온도를 강하시켜 냉기를 발생하고, 이때 발생된 냉기를 실내로 토출시키므로 냉방을 수행하게 된다.In general, an air conditioner is a type of air conditioner that compresses and liquefies a refrigerant at a high pressure with a condenser driven by a motor, and vaporizes the refrigerant in an evaporator by evaporating the refrigerant instantaneously while moving the refrigerant condensed at a high pressure to a small tube. Cold air is generated by lowering the temperature, and cooling is performed since the generated cold air is discharged into the room.

그리고, 증발기에서 증발되면서 열을 흡수하면서 기화된 냉매는 압축기에서 응축기로 이동하여 응축되어 액화되면서 열을 외부로 방출하여 상기한 과정을 거쳐지속적으로 냉방을 수행하게 된다.The refrigerant vaporized while absorbing heat while being evaporated in the evaporator is condensed by moving from the compressor to the condenser and liquefied to release heat to the outside to continuously cool through the above process.

한편, 최근에는 낭방운전과 냉방운전을 겸용으로 사용하는 냉,난방 겸용 에엌콘을 사용하고 있는 추세 있으며, 이 냉난방 겸용 에어콘은, 난방운전시에는 실외의 열을 흡수하여 실내로 방출하도록 하고, 냉방운전시에는 실내의 열을 흡수하여 실외로 방출하도록 하는 이중 작동구조를 지닌다.On the other hand, recently, there has been a trend to use a combination of cooling and heating kitchen cones that use both a cooling operation and a cooling operation. This air-conditioning dual-purpose air conditioner absorbs heat from the outside and discharges it to the interior during heating operation. In operation, it has a dual operation structure that absorbs heat from the room and releases it to the outside.

특히, 자동차에 적용중인 알루미늄재의 SCC열교환기를 가정용 에어콘의 실외기에 적용하여 사용하는 것이 바람직하고, 현재 냉난방모델에 국한하여 적용중이나 냉,난방겸용 기종에도 확대하여 적용하도록 하고 있다.In particular, it is preferable to use the SCC heat exchanger made of aluminum applied to automobiles by applying it to an outdoor unit of a household air conditioner, and is currently being applied only to a heating / cooling model, and to expand the application to a cooling / heating combined model.

도 1은 일반적인 에어콘용 실외기의 구조를 보인 도면이고, 도 2는 일반적인 실외열교환기를 보인 도면이고, 도 3은 종래의 실외열교환기의 방열구조의 단면을 보인 도면이고, 도 4는 도 3의 A-A선 단면을 보인 도면이고, 도 5는 도 4의 B-B선 단면을 보인 도면이다.1 is a view showing the structure of a conventional outdoor air conditioner, Figure 2 is a view showing a general outdoor heat exchanger, Figure 3 is a view showing a cross-sectional view of the heat dissipation structure of a conventional outdoor heat exchanger, Figure 4 is AA of Figure 3 It is a figure which shows the cross-section line, and FIG. 5 is a figure which shows the BB line cross section of FIG.

종래의 실외교환기(특히, 알루미늄재의 SCC열교환기)의 구성을 살펴 보면, 베이스판넬(3)상에 분리판(6)을 일정 부분을 분리시키도록 하고, 냉매를 고압을 압축시키는 압축기(2)와, 외부와 열을 교환하도록 하는 실외열교환기(1)가 설치되어진다.Looking at the configuration of a conventional outdoor exchanger (particularly, SCC heat exchanger made of aluminum), the compressor (2) for separating a predetermined portion of the separation plate 6 on the base panel 3, and compresses the refrigerant at high pressure. And an outdoor heat exchanger (1) for exchanging heat with the outside.

상기 실외열교환기(응축기)(1)에 인접하여 열을 교환하도록 하여 주는 구동모터(4)와 이에 결합된 송풍팬(5)이 설치되어진다.A drive motor 4 and a blower fan 5 coupled thereto are installed to allow heat exchange adjacent to the outdoor heat exchanger (condenser) 1.

상기 실외열교환기(1)의 구성을 보면, 냉매를 공급하는 냉매공급파이프(7)와 냉매를 배출하도록 하는 냉매배출파이프(11)가 헤더파이프(8)에 결합되어져 설치된다.In the configuration of the outdoor heat exchanger (1), a refrigerant supply pipe (7) for supplying a refrigerant and a refrigerant discharge pipe (11) for discharging the refrigerant are coupled to the header pipe (8).

그리고, 상기 헤더파이프(8)의 내부에 냉매가 저장되는 공간부(12)를 구비하고, 이 공간부(12)의 내측으로 냉매가 이동하도록 하는 납작한 형상의 튜브(9)가 다수 수평으로 연결되어진다.In addition, the header pipe 8 includes a space portion 12 in which the refrigerant is stored, and a plurality of flat tubes 9 horizontally connected to allow the refrigerant to move inside the space portion 12 are horizontally connected. It is done.

상기 튜브(9)의 외측으로는 주름형상의 방열핀(10)이 설치되어져서 열교환이이루어지도록 형성되고, 도 4에 도시된 바와 같이, 튜브(9)는 납작하게 펴진 상태로 형성되고, 내부에는 다수개의 냉매유로(14)가 형성되어진다.The outer side of the tube (9) is formed so that the heat dissipation fin 10 of the corrugated shape is formed to be heat exchange, as shown in Figure 4, the tube (9) is formed in a flattened state, the inside A plurality of refrigerant passages 14 are formed.

그리고, 상기 도 5는 도4의 B-B선 단면을 보인 도면으로서, 경사진 형상의 방열슬릿(13)이 다수 형성되어진다.5 is a cross-sectional view taken along the line B-B of FIG. 4, and a plurality of inclined heat radiation slits 13 are formed.

그런데, 상기한 바와 같이, 종래의실외열교환기의 튜브, 방열판 및 방열슬의 설치구조가 실외기의 설치 상태에서 수평방향을 난방시 실외온도가 저하됨에 따라 발생되는 실외열교환기 표면의 성에를 제거하기 위하여 제상운전을 수행할 때 성에를 녹여주므로 인하여 발생되는 응결수가 배수가 제대로 이루어지지 않아서 냉난방겸용 실외열교환기로 사용하기 어려운 문제점을 지닌다.However, as described above, in order to remove the frost on the surface of the outdoor heat exchanger, which is caused by the decrease in outdoor temperature when heating the horizontal direction in the installation state of the outdoor unit, the tube, heat sink and heat dissipation chain of the conventional outdoor heat exchanger. In order to dissolve frost when performing defrosting operation, condensation water generated due to poor drainage has difficulty in using as an outdoor heat exchanger for both heating and cooling.

또한, 주름형상의 방열핀에 형성된 방열슬릿구조로 인하여 이 슬릿부분에 실외의 먼지등이 적층되어지면서 열교환효율이 저하되으로 원활한 열교환효율을 제공하지 못하는 단점을 지닌다.In addition, due to the heat radiation slit structure formed on the corrugated heat radiation fins, the outdoor dust and the like is laminated on the slit portion, and the heat exchange efficiency is lowered, thereby not providing a smooth heat exchange efficiency.

본 발명은 이러한 점을 감안하여 안출한 것으로서, 방열핀에 상,하로 교번적으로 다수 절곡된 절곡슬릿부를 형성하여 공기와 접촉시에 대류현상을 향상하여 열교환 효율을 증대하는 것이 목적이다.The present invention has been made in view of this point, and the object is to increase the heat exchange efficiency by improving the convection phenomenon when contacting air by forming a plurality of bent slit portion alternately up and down on the heat radiation fin.

그리고, 도 9 및 도 10에 도시된 바와 같이 다른 실시예로서, 상기 방열핀(26)에 결합된 다수의 튜브(24) 사이에 물결 형상으로 다수 횟수 절곡되어지는 절곡슬릿부(38)를 형성하여 공기의 접촉효과를 향상하도록 한다.9 and 10, as another embodiment, a bent slit portion 38 that is bent a plurality of times in a wave shape between the plurality of tubes 24 coupled to the heat dissipation fins 26 is formed. Improve the air contact effect.

그리고, 상기 튜브(24)는 중심부분에서 양측 대칭으로 하향 경사져서 형성하도록 한다.In addition, the tube 24 is formed to be inclined downward in both sides symmetrical from the central portion.

상기 방열핀(26)에 형성되는 절곡슬릿부(38)는, 대략 "W"자 형상으로 형성하여 이동하는 공기에 대류현상이 발생하여 공기로 인하여 방열효과가 증대하도록 한다.The bent slit portion 38 formed on the heat dissipation fin 26 is formed in a substantially "W" shape so that convection occurs in the moving air, thereby increasing the heat dissipation effect due to the air.

이하, 첨부도면에 의거하여 본 발명의 작용 및 효과를 살펴 보도록 한다.Hereinafter, the operation and effects of the present invention will be described based on the accompanying drawings.

도 6에 도시된 바와 같이, 본 발명에 따른 실외열교환기(20)에 냉매가 공급되어지면, 상기 냉매공급파이프(22)로 이동하는 냉매가 헤더파이프(28)의 내부에 일차적으로 유입되어져 일시 저장되어진다.As shown in FIG. 6, when the coolant is supplied to the outdoor heat exchanger 20 according to the present invention, the coolant moving to the coolant supply pipe 22 is first introduced into the header pipe 28 to temporarily receive the coolant. Are stored.

그리고, 상기 헤더파이프(28)에 연결된 튜브(24)의 냉매유로(36)를 통하여이동하면서 반대측의 헤더파이프(28)로 이동하게 된다.Then, while moving through the refrigerant passage 36 of the tube 24 connected to the header pipe 28 is moved to the header pipe 28 on the opposite side.

이와 같이, 상기 튜브(24)를 통하여 이동하는 냉매에 포함된 열은 튜브(24)의 외측에 방열핀칼라부(34)를 통하여 방열핀(26)의 전체면으로 이동하면서 열을 외부로 배출하게 된다.As such, the heat contained in the refrigerant moving through the tube 24 moves to the entire surface of the heat dissipation fin 26 through the heat dissipation fin collar 34 on the outside of the tube 24 to discharge heat to the outside. .
