Description

냉장고의 응축기구조Condenser structure of the refrigerator

본 발명은 냉장고의 응축기에 관한 것으로, 보다 상세하게는 반원형의 단면을 가진 냉매유로홈을 각각 형성한 두 개의 철판을 서로 겹쳐서 형성된 응축기를 냉장고의 배면에 설치하여 고온고압으로 온도상승된 냉매가 응축기를 통해 냉장고의 외부로 보다 효율적으로 방열되도록 함으로써 제조원가를 낮추고 냉각효과 또한 향상되도록 한 냉장고의 응축기구조에 관한 것이다.The present invention relates to a condenser of a refrigerator, and more particularly, a refrigerant condenser that is elevated in high temperature and high pressure by installing a condenser formed by stacking two iron plates each having a refrigerant flow path groove having a semicircular cross section on the back of the refrigerator. Through a more efficient heat dissipation to the outside of the refrigerator through the condenser structure of the refrigerator to lower the manufacturing cost and improve the cooling effect.

일반적으로 잘 알려져 있듯이 냉장고 냉동싸이클상의 응축기는 압축기를 통해 고온고압을 압축된 고온의 기체냉매가 통과되면서 응축기파이프를 통해 캐비넷 외부로 열발산하여 액상의 냉매로 온도하강되는 열교환이 이루어지는 냉동싸이클상의 핵심 구성요소로서 냉매의 유입량 및 그 종류에 따라 알맞는 규격을 사용해야 한다.As is generally known, the condenser on the refrigerator refrigeration cycle is the core of the refrigeration cycle where heat and heat is discharged to the outside of the cabinet through the condenser pipe as the high-temperature, high-pressure compressed gas gas refrigerant passes through the compressor and passes through the condenser pipe As a component, suitable specifications should be used depending on the amount of refrigerant introduced and its type.

상기의 응축기는 증발기의 열교환에 의해 가스화된 냉매를 고온고압으로 압축시키는 압축기와 고온고압의 냉매가스가 직접 증발기로 유입되는 것을 막는 캐필러리튜브 사이에 연결되어서 캐비넷의 내측면에 테이핑처리되는 결합구조를 이루고 있다.The condenser is coupled between the compressor for compressing the refrigerant gasified by the heat exchange of the evaporator at high temperature and high pressure and the capillary tube which prevents the refrigerant gas of high temperature and high pressure from directly flowing into the evaporator, thereby being taped to the inner surface of the cabinet. It is structured.

이러한 응축기는 종래 기술의 경우 제1(a)도에 도시된 바와 같이, 판상의 후판(81)에 원통형의 응축기파이프(82)를 알미늄테이프(83)로 테이핑하여 그 접촉면이 살짝 1차원 선접촉되어 통과되는 정도이므로 고온의 냉매가스가 응축기파이프(82)의 접촉부위를 통해 후판(81)에 열전달되어 외부로 열발산되는 방열효과가 제대로 이루어지지 못하였으며 그에 따른 응축기파이프(82)의 열발산을 높여주기 위해 응축기파이프(82)의 전열면적(길이)이 늘어나 결과적으로 응축기파이프(82)의 제작비와 그 설치비가 증가되는 등의 구조적인 문제점이 있었다.Such a condenser taps a cylindrical condenser pipe 82 with aluminum tape 83 on a plate-shaped thick plate 81 with aluminum tape 83, as shown in FIG. 1 (a). Since the high temperature refrigerant gas is transferred to the rear plate 81 through the contact portion of the condenser pipe 82, the heat dissipation effect of heat dissipation to the outside was not properly achieved, and thus the heat dissipation of the condenser pipe 82 was achieved. In order to increase the heat transfer area (length) of the condenser pipe 82 is increased, as a result, there was a structural problem such as manufacturing cost and installation cost of the condenser pipe 82 is increased.

한편, 제1(b)도에 도시된 바와 같이, 다수개의 와이어(84)에 응축기파이프(82)가 용접결합되어진 와이어콘 타입(wire-con type)응축기는 방열효과나 작업안정성은 양호하나 제조원가가 높은 문제점이 있었다.On the other hand, as shown in FIG. 1 (b), the wire-con type condenser, in which the condenser pipe 82 is welded to the plurality of wires 84, has good heat dissipation effect and work stability, but has high manufacturing cost. There was a high issue.

이러한 문제점을 해결하기 위하여 본 발명 냉장고의 응축기구조는 반원형의 단면을 가진 냉매유로홈을 각각 형성한 내판과 외판을 서로 겹쳐서 형성한 응축기를 냉장고의 배면에 후판으로 채용하여 설치하도록 함으로써 고온고압으로 온도상승된 냉매가 응축기를 통해 냉장고 외부로 보다 효율적으로 방열시킴으로써 냉각효과를 향상시킬 뿐 아니라 제조원가를 낮출 수 있는 냉장고의 응축기구조를 제공하는 것을 그 기술적과제로 한다.In order to solve this problem, the condenser structure of the refrigerator of the present invention has a high temperature and high pressure by installing a condenser formed by overlapping the inner and outer plates each having a refrigerant flow path groove having a semicircular cross section on the rear surface of the refrigerator. The technical problem is to provide a condenser structure of a refrigerator in which the elevated refrigerant radiates more efficiently through the condenser to the outside of the refrigerator, thereby improving the cooling effect and lowering the manufacturing cost.

상기 내판(10)의 후측에 결합되어지는 외판(20)에는 상기 내판(10)에 형성된 냉매유로홈(11)과 상호 대응되도록 반원형의 단면을 가진 냉매유로홈(21)이 상기 냉매유로홈(11)과 일치되게 형성되고 또한 상기 내판(10)에 형성된 방열공(50) 및 볼트삽입공(40)과 일치되도록 방열공(50)이 천공되어진다.In the outer plate 20 coupled to the rear side of the inner plate 10, a refrigerant passage groove 21 having a semicircular cross section is formed to correspond to the refrigerant passage groove 11 formed in the inner plate 10. The heat dissipation hole 50 is perforated to coincide with the heat dissipation hole 50 and the bolt insertion hole 40 formed in the inner plate 10 and formed in accordance with 11).

한편 냉매유로홈(11), (21)과 볼트삽입공(40)과 방열공(50)이 각각 상호 대응되게 형성되어있는 내판(10)과 외판(20) 사이에는 구리박판(30)을 개재시켜 전기저항용접을 실시하여 상기 내판(10)과 외판(20)을 결합시키는데 상기 구리박판(30)은 상기 내판(10)과 외판(20)에 형성되어있는 냉매유로홈(11), (21)과 대응되는 형상으로 절결된 절결부(35)와 방열공(50)과 볼트삽입공(40)이 형성되어진다.Meanwhile, a copper thin plate 30 is interposed between the inner plate 10 and the outer plate 20 in which the coolant flow path grooves 11, 21, the bolt insertion hole 40, and the heat dissipation hole 50 are formed to correspond to each other. Electrical resistance welding to bond the inner plate 10 and the outer plate 20. The copper thin plate 30 is a coolant flow path 11 or 21 formed in the inner plate 10 and the outer plate 20. The cutout part 35, the heat dissipation hole 50, and the bolt insertion hole 40 cut into a shape corresponding to) are formed.

그리하여 상기 구리박판(30)을 내판(10)과 외판(20) 사이에 개재시켜 전기저항용접을 실시하면 상기 내판(10)과 외판(20)의 냉매유로홈(11), (21)과 방열공(50)과 볼트삽입공(40)을 제외한 전면적에 개재된 구리박판(30)이 녹으면서 긴밀하게 결합되게 된다.Thus, when the copper thin plate 30 is interposed between the inner plate 10 and the outer plate 20 to perform electrical resistance welding, the coolant flow paths 11, 21 and the room of the inner plate 10 and the outer plate 20 are formed. The copper plate 30 interposed on the entire surface except for the hot hole 50 and the bolt insertion hole 40 is melted and is closely coupled.

따라서 상기 내판(10)과 외판(20)의 각 냉매유로홈(11), (21)이 결합된 부위에는 원형단면의 냉매유로(90)가 형성되고 상기 냉매유로(90) 주위에는 다수개의 방열공(50)이 형성되고 각 모서리에는 볼트삽입공(40)이 형성되는 것이다.Therefore, the refrigerant passages 90 of circular cross-sections are formed at the portions where the refrigerant passage grooves 11 and 21 of the inner plate 10 and the outer plate 20 are coupled, and a plurality of rooms are formed around the refrigerant passage 90.
