Description
본 발명은 응축기의 열교환기에 관한 것으로서, 특히 전기기관차운전실에 전용으로 설치하여 사용할 수 있도록 된 것이다.The present invention relates to a heat exchanger of the condenser, in particular to be installed and used in the electric locomotive operating room.
이를 좀더 상세히 설명하면, 링 형상으로 형성된 복수개의 링형냉매관을 다열 로 내/외측에 배열하고, 다열로 내/외측에 배열된 상기 링형냉매관에 전열핀을 등 간격으로 삽입 설치하여 원통형의 코일어셈블리를 형성하며, 상기 코일어셈블리를 장치틀의 내부에 설치하여서 된 것이다.To describe this in more detail, a plurality of ring-shaped refrigerant pipes formed in a ring shape are arranged inside / outside the multi-row furnace, and the heating coils are inserted into the ring-shaped refrigerant pipes arranged inside / outside the multi-row furnace at equal intervals to form a cylindrical coil. The assembly is formed, and the coil assembly is installed inside the apparatus frame.
통상적으로 전기기관차를 포함하는 자동차에 설치되어 사용되는 냉방시스템은 압축기 →응축기 →팽창밸브 →증발기 →압축기로 이루어지는 순환경로를 실행하게 되며, 상기 순환경로에서 냉매는 액화 및 기화되는 작용을 반복적으로 수행하게 된다.In general, a cooling system installed and used in an automobile including an electric locomotive executes a circulation path consisting of a compressor, a condenser, an expansion valve, an evaporator, and a compressor, in which a refrigerant repeatedly liquefies and vaporizes. Done.
상기에서 압축기는 흡입되는 냉매를 고온ㆍ고압으로 압축하여 응축기로 보내게 되고, 응축기는 고온ㆍ고압으로 변환된 냉매가스를 액화시키게 되는데 주로 라디에이터의 전면에 설치되어 외기 및 라디에이터의 냉각 팬에 의해 냉각되어지며, 팽창밸브는 유입되는 액상의 냉매를 팽창시켜 저온ㆍ저압의 냉매로 변환시켜 주게 되며, 증발기는 팽창밸브를 통과한 냉매를 증발 기화시켜 주위의 열과 열 교환을 실시하여 냉방 및 제습을 실시하게 된다.The compressor compresses the refrigerant sucked at high temperature and high pressure and sends it to the condenser, and the condenser liquefies the refrigerant gas converted to high temperature and high pressure. It is mainly installed at the front of the radiator and cooled by the cooling fan of the outside air and the radiator. The expansion valve expands the liquid refrigerant flowing into the refrigerant at low temperature and low pressure, and the evaporator evaporates and evaporates the refrigerant passing through the expansion valve to exchange heat and surroundings for cooling and dehumidification. Done.
상기와 같이 구성되는 냉방시스템에서 종래 응축기의 열교환기는 직선형의냉매관을 다 열종대로 설치하고, 다열 종대로 배열된 냉매관에 패널형태의 전열핀을 삽입하여 등 간격으로 설치하며, 양측 전열핀의 외측으로 노출되는 냉매관을 ∪형으로 벤딩(Bending)된 연결관으로 연결하여 플레이트형(일명 : 핀-튜브형(Fin-Tube Type))으로 형성하였었다.In the cooling system configured as described above, the heat exchanger of the conventional condenser is installed with a plurality of linear coolant pipes in ten rows, and is inserted at equal intervals by inserting panel-type heating fins into the coolant pipes arranged in multiple rows. The refrigerant tube exposed to the outside of the tube was connected to the bent (Bending) connecting tube was formed in a plate type (aka: Fin-Tube type).
이와 같이 된 플레이트형으로 된 종래의 열교기는 송풍팬에 의해 송풍되는 공기와 직접 접촉하여 열 교환을 수행하는 부위가 중심부에 집중되어 있어 중심부에서는 열 교환이 활발하게 이루어지지만, 열교환기의 가장자리에서는 열 교환이 활발하게 이루어지지 못하여 매우 낮은 효율을 얻게 되는 문제가 있었고, 이를 다소나마 해소하기 위하여 열교환기와 송풍팬과의 간격을 넓혀 주거나 임펠러가 큰 송풍팬을 사용하기도 하지만 설치공간이 확대되고 전력이 많이 소요될 뿐 열 교환 효율을 크게 증대시킬 수 없는 문제가 있었다.Conventional heat bridges in the form of plates have a part where heat exchange is performed in direct contact with the air blown by the blower fan, so the heat exchange is actively performed at the center, but at the edge of the heat exchanger, There was a problem that the exchange could not be made actively and very low efficiency was obtained.To solve this problem, the gap between the heat exchanger and the blower fan was widened, or the blower fan with a large impeller was used, but the installation space was enlarged and the power was large. There was a problem that can not significantly increase the heat exchange efficiency.
이와 같은 문제를 해소하기 위하여 제안된 것으로는 국내 공개특허 공개번호 제 2002-94212호 "원통형 열교환기"가 알려져 있다.Proposed in order to solve such a problem is known Korean Patent Publication No. 2002-94212 "cylindrical heat exchanger".
이는 전열핀을 판상의 링 형상으로 형성하되 전열핀에 냉매관장착공을 등 간격으로 통공하여 전열핀을 등 간격으로 배치하여 동일 수평선상의 각 냉매관장착공에 냉매관을 각각 삽입하여 용접하여 고정시키되 양측 전열핀의 외측으로 노출되는 냉매관을 ∪형으로 된 연결관으로 일체형으로 연통되게 연결시켜 원통형 열교환기를 형성하고, 원통형 열교환기의 내부 중앙에 송풍팬을 장착하여서 된 것이다.It is formed in the plate-shaped ring shape of the heat transfer fins through the coolant pipe mounting holes through the equal intervals, the heat transfer pins are arranged at equal intervals, and the refrigerant pipes are inserted into each of the refrigerant pipe mounting holes on the same horizontal line to be fixed by welding. The refrigerant pipes exposed to the outside of the heat transfer fins are integrally connected to each other by a fin-shaped connecting pipe to form a cylindrical heat exchanger, and a blower fan is mounted on the inner center of the cylindrical heat exchanger.
그러나 이와 같이 구성된 종래의 원통형 열교환기는 냉매관의 단선형으로 형성 되어 있으므로 냉매의 이송능력이 떨어지는 문제가 있었고, 전열핀이 원판의 링형상으로 형성되어 있으므로 냉매관과의 접촉 면적이 작아 냉매관의 냉기를 효율적으로 전달할 수 없었을 뿐만 아니라 열 교환면적이 작아 열 교환효율이 현저하게 떨어지는 문제가 있었다.However, the conventional cylindrical heat exchanger configured as described above has a problem in that the transfer capacity of the refrigerant is lowered because it is formed in a single line of the refrigerant pipe, and the contact area with the refrigerant pipe is small because the heat transfer fin is formed in a ring shape of the disc. Not only could not efficiently transport cold air, but the heat exchange area is small, there was a problem that the heat exchange efficiency is significantly reduced.
특히, 전열핀이 원판의 링 형상으로 되어 있으므로 용량을 달리하면서 용이하게 성형 제조할 수 없는 문제가 있었다.In particular, since the heat transfer fin has a ring shape of a disc, there is a problem in that it cannot be easily molded and manufactured with different capacities.
본 발명은 상기와 같은 문제를 해소할 수 있도록 더욱 개선된 응축기용 열교환기를 제공하려는 것이다.The present invention is to provide a heat exchanger for a condenser further improved to solve the above problems.

An object of the present invention is to provide a heat exchanger for forming a coil assembly and having a conventional blowing fan inside the coil assembly and installed inside the apparatus frame.
본 발명의 다른 목적은 링 형상으로 된 복수 개의 냉매관을 다열로 내/외측에 배열하여 줌으로써 냉매의 공급능력을 향상시켜 줄 수 있도록 하고, 내/외측에 다열로 배열된 냉매관에 전열핀을 등 간격으로 삽입 설치하여 냉매관과 전열핀과의 접촉면적을 증가시키고 냉기를 효율적으로 전달하여 열 교환 효율(능력)을 크게 향상시킬 수 있도록 된 응축기용 열교환기를 제공하는데 있다.Another object of the present invention is to improve the supply capacity of the refrigerant by arranging a plurality of refrigerant pipes in a ring shape in the inner / outer row in a multi-row, and heating fins in the refrigerant pipe arranged in a multi-row in the inner / outer By inserting at regular intervals, the present invention provides a heat exchanger for a condenser that increases the contact area between the refrigerant pipe and the heating fins and efficiently transfers cool air to greatly improve the heat exchange efficiency (capacity).
본 발명의 또 다른 목적은 링 형상으로 형성된 코일어셈블리의 내부에 설치된 송풍팬의 풍력이 외측에 형성된 코일어셈블리를 통과하도록 하여 열 교환(냉방)효율을 크게 향상시킬 수 있도록 된 응축기용 열교환기를 제공하는데 있다.It is still another object of the present invention to provide a heat exchanger for a condenser that allows the wind power of a blowing fan installed inside a coil assembly formed in a ring shape to pass through the coil assembly formed on the outside, thereby greatly improving heat exchange (cooling) efficiency. have.

상기와 같이 장치틀(2)의 내부에 설치되는 코일어셈블리(20)의 중앙에는 원통형상으로 된 임펠러하우징(11)의 내부 중앙에 모터(12)가 장착되고 모터(12)에 의해 임펠러(13)가 회전하도록 된 통상의 송풍팬(10)을 설치하였는데, 장치틀(2)의 양측의 측면지지판(5)의 중앙에 설치하여 송풍팬(10)에서 발생되는 바람이 외측에 설치된 링형상의 코일어셈블리(20)에 고르게 송풍시킬 수 있도록 하였으며, 양측의 측면지지판(5)은 등 간격으로 설치되는 지지봉(15)에 의해 서로 고정시켜 주었다.As described above, the motor 12 is mounted on the inner center of the cylindrical impeller housing 11 at the center of the coil assembly 20 installed inside the apparatus frame 2, and the impeller 13 is mounted by the motor 12. Is installed in the center of the side support plate (5) on both sides of the apparatus frame (2), the wind generated from the blower fan (10) is formed in a ring shape The coil assembly 20 was allowed to be evenly blown, and the side support plates 5 on both sides were fixed to each other by the support rods 15 installed at equal intervals.
이하, 작동관계를 설명한다.The operation relationship will be described below.
상기와 같이 형성된 본 발명에 따른 열교환기(1)는 도 4에 예시된바와 같이 설치공간이 협소한 전기기관차운전실(40) 등에 주로 설치하여 사용하게 된다.The heat exchanger 1 according to the present invention formed as described above is mainly installed and used in the electric locomotive operating room 40, etc., where the installation space is narrow as illustrated in FIG.
공급관(24)을 통하여 공급되는 냉매(가스)는 동일 수직열에 설치된 복수개씩의 링형냉매관(21)들을 순차적으로 순환하여 통과한 후에 배출관(25)을 통하여 배출되어진다.The refrigerant (gas) supplied through the supply pipe 24 is sequentially discharged through the plurality of ring-shaped refrigerant pipes 21 installed in the same vertical row and then discharged through the discharge pipe 25.
이와 같이 냉매(가스)가 링형냉매관(21)을 통과할 때에 복수개의 링형냉매관(21)에 동시 다발적으로 공급되어 통과하게 되므로 각 링형내매관(21)은짧은 시간에 냉각되어지고, 이와 같이 각 링형냉매관(21)이 동시 냉각되어지면 냉기는 링형냉매관(21)과 접촉되어 있는 각 전열핀(22)에 동시에 전이되어지며, 각 링형냉매관(21)을 통하여 동시 다발적으로 냉기가 전이된 전열핀(22)은 신속하게 냉각상태를 유지하게 된다.Thus, when the refrigerant (gas) is passed through the ring-shaped refrigerant pipe 21, the plurality of ring-shaped refrigerant pipes 21 are simultaneously supplied and passed through, so each ring-shaped inner pipe 21 is cooled in a short time, As described above, when each ring-shaped refrigerant pipe 21 is simultaneously cooled, the cold air is simultaneously transferred to each heat-transfer fin 22 in contact with the ring-shaped refrigerant pipe 21, and simultaneously through multiple ring-shaped refrigerant pipes 21. The heat transfer fins 22 having the cold air transferred thereto are quickly maintained in a cooled state.
이와 같이 냉기가 전이되고 있는 상태에서 송풍장치(10)가 작동하게 되는 데, 송풍장치(10)의 모터(12)가 작동하게 되면 임펠러(13)가 회전하게 되고, 임펠러(13)가 회전하면서 발생되는 바람은 임펠러하우징(11)을 통하여 원호를 이루고 있는 코일어셈블리(20)로 송풍되어지며, 코일어셈블리(20)로 송풍되어진 바람은 냉각상태로 유지되고 있는 전열핀(22)과 냉매관(21)의 사이사이로 유입되어 통과하면서 냉기와 열 교환을 실시하여 냉기로 변환되어진다.As the blower 10 operates in a state where the cold air is transferred as described above, when the motor 12 of the blower 10 operates, the impeller 13 rotates, and the impeller 13 rotates. The generated wind is blown to the coil assembly 20 forming an arc through the impeller housing 11, and the wind blown to the coil assembly 20 is heated with the heat transfer fin 22 and the refrigerant pipe ( It is converted into cold by performing heat exchange with cold as it flows in and passes between 21).
냉각상태를 유지하고 있는 전열핀(22)과 냉매관(21)의 사이사이를 통과하여 냉기로 변환되어지는 냉풍은 원호상태를 유지하고 있는 전열핀(22)을 완전히 통과하여 360도 모든 부분에서 냉풍이 발생하게 되고, 발생된 냉풍은 장치틀(2)을 통하여 소정의 개소로 송풍되어지면서 실내를 냉방상태를 유지시켜 주게 되는데, 예컨대 도 4에 예시된바와 같이 전기기관차운전실(40)을 냉방상태로 유지시켜 주게 되는 것이다.The cold air that is converted into cold by passing between the heat transfer fins 22 and the coolant pipe 21 that maintains the cooling state completely passes through the heat transfer fins 22 that maintains the arc state. Cold air is generated, and the generated cold air is blown to a predetermined position through the apparatus frame 2 to maintain the cooling state of the room. For example, as shown in FIG. 4, the electric locomotive cab 40 is cooled. Will be kept in a state.
이상에서와 같이 본 발명에 따른 응축기의 열교환기는, 링 형상으로 형성된 복수개의 링형냉매관을 다열로 내/외측에 배열하고 링형냉매관에 평판 형상으로 된 전열핀을 등 간격으로 삽입 설치하여 원통형의 코일어셈블리를 형성하였으므로 냉매의 공급능력을 향상시켜 줄 수 있고, 냉매관과 전열핀과의 접촉면적을 증가시키고 냉기를 효율적으로 전달하여 열 교환 효율(능력)을 크게 향상시킬 수 있으며, 중앙에서 설치된 송풍팬에서 발생된 바람이 원통형의 형상으로 형성된 코일어셈블리를 통과하여 360도 전체에서 냉기를 발생시키므로 냉방효율을 크게 향상시킬 수 있으며, 전기기관차운전실과 같이 특정한 실내에 설치하여 사용할 수 있게 된다.As described above, the heat exchanger of the condenser according to the present invention has a plurality of ring-shaped refrigerant pipes formed in a ring shape inside and outside of a multi-stage furnace, and the plate-shaped heat transfer fins are inserted into the ring-shaped refrigerant pipes at equal intervals to form a cylindrical shape. Since the coil assembly is formed, the supply capacity of the refrigerant can be improved, the contact area between the refrigerant pipe and the heating fins can be increased, and the cold air can be efficiently transferred to greatly improve the heat exchange efficiency (capacity). Since the wind generated from the blowing fan passes through the coil assembly formed in a cylindrical shape to generate cold air at 360 degrees, the cooling efficiency can be greatly improved, and it can be installed in a specific room such as an electric locomotive cab.
