본 고안은 음식물을 신선하게 보관하기 위한 냉장고에서 냉장고내의 열을 흡수하는 증발기의 냉가핀에 관한 것으로 증발기의 열 흡수효율을 높일 수 있도록 표면을 형성한 냉각핀에 관한 것이다.The present invention relates to a cold fin of the evaporator that absorbs heat in the refrigerator in a refrigerator for storing food freshly, and relates to a cooling fin having a surface formed to increase the heat absorption efficiency of the evaporator.

일반적으로, 냉장고는 크게 압축기, 응축기, 팽창밸브와 증발기로 구성되어 프레온가스와 같은 냉매를 이용하여 냉장고내의 공기로 부터 열을 흡수하여 냉장고내의 공기를 냉각시키는 장치로서 가장 핵심적인 부분은 냉장고내의 공기로부터 열을 흡수하는 증발기이다.In general, a refrigerator is mainly composed of a compressor, a condenser, an expansion valve, and an evaporator, and uses a refrigerant such as freon gas to absorb heat from the air in the refrigerator to cool the air in the refrigerator. It is an evaporator that absorbs heat from.

여기서, 상기 증발기(100)는 응축기에서 액체상태로 된 냉매를 팽창밸브를 통하여 기체상태로 공급받는데, 이때 기체상태로 된 냉매는 저온상태 이므로 증발기(100)는 증발기관(30) 주위에 형성한 냉각핀(20)에 의하여 냉장고내의 공기중에서 열을 흡수하여 냉장고내의 공기를 냉각시켜 냉장고가 냉장고의 역활을 할 수 있도록 하는 것이다.Here, the evaporator 100 receives a refrigerant in a liquid state in a condenser in a gas state through an expansion valve, and since the refrigerant in a gas state is a low temperature state, the evaporator 100 is formed around the evaporator 30. The cooling fins 20 absorb heat from the air in the refrigerator to cool the air in the refrigerator so that the refrigerator can serve as a refrigerator.

이상과 같이 냉장고내의 공기를 냉각시키는 증발기(100)의 성능은 냉각핀(20)의 재질과 접열면적에 따라 결정지어지는 것으로, 상기 냉각핀(20)은 열전달 계수가 높은 알루미늄을 사용함과 더불어 접열면적을 최대로 형성되게 하여 공기와 직접적인 접촉을 통하여 많은 열 흡수를 할 수 있도록 형성한 것이다.As described above, the performance of the evaporator 100 for cooling the air in the refrigerator is determined according to the material and the contact area of the cooling fins 20. The cooling fins 20 are used together with the high heat transfer coefficient. The maximum area is formed to allow a large amount of heat absorption through direct contact with air.

그러므로, 종래에는 제1도에 도시된 도면과 같이 냉장고의 성능을 향상시키기 위해 열전달 계수가 높은 금속으로 냉각핀(20)을 제작하고 냉각핀(20)을 촘촘한 간격으로 형성하여 공기와 접하는 면적을 넓혀 공기로 부터 많은 열을 흡수할 수 있도록 하여 냉각 효율을 높이고 주위에는 엠보싱(Embosing) 처리에 의하여 리브(21)를 구비하여 변형을 방지하였다.Therefore, in the related art, in order to improve the performance of the refrigerator as illustrated in FIG. 1, the cooling fins 20 are made of metal having high heat transfer coefficients, and the cooling fins 20 are formed at close intervals to contact the air. It was widened to absorb a lot of heat from the air to increase the cooling efficiency and the ribs 21 were provided around the embossing treatment to prevent deformation.

그러나, 냉각핀(20)과 냉각핀(20) 사이의 간격이 좁아 결로현상으로 생성된 물이 얼어서 성애로 되어 냉각핀(20)과 냉각핀(20) 사이를 막아 공기저항을 발생시켜 냉각핀(20)이 공기로 부터 열 흡수를 하지 못하고, 냉각핀(20)사이의 간격을 좁게 배치함으로 재료비가 많이 드는 등 여러 가지 문제점들이 발생되었다.However, the gap between the cooling fins 20 and the cooling fins 20 is narrow, so that the water generated by the condensation phenomenon is frozen and the frost is formed to block air between the cooling fins 20 and the cooling fins 20 to generate air resistance. Various problems have occurred such that the material 20 does not absorb heat from the air and the material is expensive due to the narrow spacing between the cooling fins 20.

본 고안은 위와 같은 문제점을 해결하기 위하여 안출한 것으로 공기가 냉각핀에 고루 접하고 난류흐름을 유도할 수 있도록 슬리팅부를 형성한 것이다.The present invention has been made in order to solve the above problems is to form a slitting portion so that the air is in contact with the cooling fins and induce turbulent flow.

이하 도면에 의하여 상세히 설명한다.Hereinafter, the drawings will be described in detail.

제2도와 제3도에 도시된 도면과 같이 냉장고내의 공기가 냉각핀(10)과 고루 접할 수 있도록 함과 더불어 냉각핀(10)의 전후면을 따라 흐르는 공기가 고르게 혼합될 수 있도로 길이방향으로 길게 절개하여 공기통로(11a)가 형성되게 절개된 절개편(11b)를 절곡형성하여 경사지게 돌출형성한 슬리팅부(11)를 형성하되, 증발기관(30)이 결합되는 결합구(22)의 슬리팅부(11)는 열전달이 용이하게 방사형으로 형성하고 상하 결합구(22) 사이의 슬리팅부(11)는 길이방향으로 길게 형성한 것이다.As shown in FIG. 2 and FIG. 3, the air in the refrigerator may be in contact with the cooling fins 10, and the air flowing along the front and rear surfaces of the cooling fins 10 may be evenly mixed. The slitting portion 11 is formed to be bent to form a slanted protruding portion by bending the cut piece 11b cut to form an air passage 11a so that the air passage 11a is formed. The slitting part 11 is formed to be easily radial in heat transfer, and the slitting part 11 between the upper and lower coupling holes 22 is formed to be long in the longitudinal direction.

한편, 상기 결합구(22)와 결합구 사이의 슬리팅부(11)는 중앙에서 양측으로 공기통로(11a)가 개구되게 형성한 것이다.On the other hand, the slitting portion 11 between the coupler 22 and the coupler is formed to open the air passage (11a) from the center to both sides.

본 고안의 다른 실시예로는 제4도에 도시된 바와 같이 공기통로(11a)의 개구방향의 서로 다른 방향으로 개구되어 냉각핀(10) 전후면의 공기가 상호 혼합되게 절곡형성되어 돌출되는 돌출편(11b)의 돌출형상이 V형 형성되게 한 것으로, 냉각핀(10)의 주위를 흐르는 공기가, 전후면을 따라 이동되며 상호 혼합되어 주변공기의 냉각이 고루고 원활하게 이루어지는 것이다.In another embodiment of the present invention, as shown in Figure 4 is opened in different directions of the opening direction of the air passage (11a) protruding bent to protrude to form a mixture of air on the front and rear surfaces of the cooling fin (10) The protruding shape of the piece 11b is V-shaped, and the air flowing around the cooling fins 10 is moved along the front and rear surfaces and mixed with each other to uniformly and smoothly cool the surrounding air.

이하, 본 고안의 작용과 효과에 대하여 상세히 설명하면 다음과 같다.Hereinafter, the operation and effects of the present invention will be described in detail.

상기한 바와 같이 형성된 냉각핀(10)을 사용하므로 냉각핀(10) 주위를 따라 흐르던 공기는 돌출된 슬리팅부(11)의 공기통로(11a)를 따라 흘러 타면의 공기와 섞여 빠른 냉각이 된다.Since the cooling fins 10 formed as described above are used, the air flowing along the cooling fins 10 flows along the air passage 11a of the protruding slitting portion 11 and is mixed with the air of the other surface to provide rapid cooling.

또한, 냉각핀(10)으로 부터 일정한 거리이상 떨어져 직접 접촉되지 않는 공기를 돌출된 절개편(11b)에 의하여 냉각하므로 공기의 냉각이 고루게 이루어진다.In addition, since the air that is not directly contacted by a predetermined distance or more from the cooling fins 10 is cooled by the protruding cutouts 11b, the cooling of the air is made even.

그리고, 증발기관(30)이 삽입되는 결합구(22) 주위에는 열 전달의 특성에 알맞게 슬리팅부(11)를 방사형으로 형성함으로 냉각핀(10)으로 부터 증발기관(30)으로 열 흡수가 잘 이루어진다.In addition, the slitting part 11 is radially formed around the coupling port 22 into which the evaporation engine 30 is inserted, so as to absorb heat well from the cooling fin 10 to the evaporation engine 30. Is done.

한편, 냉장고의 냉각기능을 높이기 위하여 압축기와 냉각팬의 회전으로 빠르게 하면 하면 공기의 냉각이 냉각핀(10)을 촘촘하게 배치하여 공기를 냉각시키는 것이 아니라 슬리팅부(11)에 의하여 냉각시키므로 공기의 흐름이 원활하여 냉각효율의 변화없이 냉각능력을 증가시킬 수 있다.On the other hand, when the compressor and the cooling fan are rotated quickly to increase the cooling function of the refrigerator, the air is cooled by the slitting part 11 instead of cooling the air by closely placing the cooling fins 10. This smoothly increases the cooling capacity without changing the cooling efficiency.

따라서, 본 고안은 냉각핀 주위를 흐르는 공기의 냉각이 원활하게 이루어지고, 특히, 상기 냉각핀의 전·후면을 따라 흐르는 공기가 공기통로를 따라 상호 혼합되어 고루게 냉각되며, 아울러 냉각핀으로부터 일정거리 이상 떨어진 공기까지 냉각하므로 전체적인 냉각효과가 상승되는 매우 유용한 것이다.Therefore, the present invention smoothly cools the air flowing around the cooling fins, and in particular, the air flowing along the front and rear surfaces of the cooling fins is mixed with each other along the air passages to be cooled evenly, and also from the cooling fins It cools the air farther away and is very useful to increase the overall cooling effect.
