본 고안은 밀폐형 전동 압축기의 내부 구조에 관한 것으로 냉각능력 향샹으로 운전 효율의 증대 및 소음 저감효과를 얻을수 있도록 하기에 적당한 흡입냉매 가스 냉각부를 흡입관과 흡입연결관 사이에 설치한 전동압축기의 흡입 냉매 가스 냉각장치에 관한 것이다.The present invention relates to an internal structure of a hermetic electric compressor, and the suction refrigerant gas of the electric compressor provided with a suction refrigerant gas cooling unit provided between the suction pipe and the suction connection pipe to improve the cooling capacity and to obtain the operation efficiency and the noise reduction effect. It relates to a cooling device.
종래의 밀폐형 전동 압축기는 구성 설치된 냉동 시스템을 환류하여 압축기로 들어오는 냉매가스가 흡입 연결관에 의해 압축기 내부로 들어와서 압축기의 내부공간을 거쳐서 흡입관으로 직접들어가는 구성으로 이루어져 있음을 제1도에 의해 알 수 있다.The conventional hermetic electric compressor is refluxing the installed refrigeration system and the refrigerant gas coming into the compressor enters into the compressor by the suction connection pipe and enters the suction pipe directly through the internal space of the compressor according to FIG. Can be.
그러나 압축기의 외부로 부터 들어오는 냉매가스는 냉동시스템의 사용조건, 주위온도, 냉동 제품의 부하, 냉동제품의 요구 냉동온도 설정에 따라 압축기로 들어오는 온도는 달라지게 된다.However, the refrigerant gas coming from the outside of the compressor is different depending on the operating conditions of the refrigeration system, the ambient temperature, the load of the frozen product, and the required refrigeration temperature of the frozen product.
이러한 외부조건과 압축기의 운전시 발생되는 열에 의해서 압축기 내부의 본체와 내부공간의 온도는 흡입되는 냉매가스의 온도보다 높으므로 실제 흡입관을 통하여 들어오는 냉매가스의 온도는 흡입연결관을 통과할 때의 온도보다 높아지게 된다.Due to these external conditions and the heat generated during the operation of the compressor, the temperature of the main body and the internal space of the compressor is higher than the temperature of the refrigerant gas being sucked. Therefore, the temperature of the refrigerant gas entering through the suction pipe is the temperature when passing through the suction connection pipe. Higher.
따라서 냉매의 특정에 의해 흡입 냉매가스의 밀도가 극히 낮아져서 냉각특성이 현저하게 저하되어 냉동성능이 급격히 저하되는 문제점이 있었고 냉매가스 흡입시 발생되는 흡입관의 파이프 고유 진동수에 의한 소음도 압축기 전체에서 발생하는 소음에 상당한 비중을 차지하게 되는 문제점이 있었다.Therefore, due to the specification of the refrigerant, the density of the intake refrigerant gas is extremely low, so the cooling characteristics are remarkably degraded, and thus the refrigeration performance is drastically degraded. There was a problem that occupies a significant proportion.
상기 여러가지 문제점들은 전동 압축기의 운전상에 지대한 영향을 미치게 되므로 그 문제점들을 본 고안의 흡입냉매 가스 냉각 장치로 해결하고자 한다.Since the various problems have a great influence on the operation of the electric compressor, the problems are solved by the suction refrigerant gas cooling device of the present invention.
제2도는 흡입냉매 가스 냉각 장치의 단면도로 밀폐형 전동 압축기(20)내에 설치된 흡입관(12)의 외면에 별도의 냉매 가스 냉각부(14)를 설치하고 흡입 연결관(6)을 흡입관(12)의 위치로 이동시켜 근접한 곳에 설치하는 구성을 형성한다.2 is a cross-sectional view of the suction refrigerant gas cooling device, and a separate refrigerant gas cooling unit 14 is installed on the outer surface of the suction tube 12 installed in the hermetic electric compressor 20 and the suction connection tube 6 is connected to the suction tube 12. Move to the position to form a configuration to be installed in close proximity.
제3도는 제2도중 A부에 대한 확대도로 A부는 흡입 냉매가스의 온도를 1차적으로 식히기 위한 냉매가스 냉각부(14)이고 그 가스 냉각부의 구성은 흡입관(12)의 외주연에형으로 절곡 형성한 밀폐열전도관(16)을 부착하여 밀폐열전도관(16)의 밀폐된 내부에 냉매(18)를 채운다.FIG. 3 is an enlarged view of part A in FIG. 2 and part A is a refrigerant gas cooling unit 14 for primarily cooling the temperature of the suction refrigerant gas. A hermetic heat conduction tube 16 bent into a shape is attached to fill the refrigerant 18 in the sealed interior of the hermetic heat conduction tube 16.
그리고 흡입 냉매가스의 입구부분 즉 흡입연결관(6)의 위치에 원판의 방열판(15)을 설치하여 유동하지 않게 밀폐 열전도관(16)의 상부에 용접으로 고정한다.Then, the heat sink 15 of the disc is installed at the inlet portion of the suction refrigerant gas, that is, the suction connection pipe 6, and fixed by welding to the upper portion of the sealed heat conductive pipe 16 so as not to flow.
상기의 구성으로 냉동시스템에 의해 압축전동기로 흡입되는 냉매가스는 흡입관(12)으로 직접 유입되지 못하고 방열판(15)에 부딪히고 돌아서 흡입된다.With the above configuration, the refrigerant gas sucked into the compression motor by the refrigeration system is not directly introduced into the suction pipe 12, but is hit by the heat sink 15 and turned around.
이러한 구성으로 된 본 고안의 동작은 전원이 전동 압축기(20)에 인입되므로서 시작되는 것으로 먼저 전동기부(1)의 회전자(2)에 고정된 주축(3)이 회전한다.The operation of the present invention having such a configuration starts with the power being drawn into the motor-compressor 20. First, the main shaft 3 fixed to the rotor 2 of the electric motor unit 1 rotates.
따라서 압축기부(5)의 피스톤(4)이 실린더(4a)내에서 왕복운동을 반복하여 구성된 냉동 시스템의 냉동 싸이클에서 냉매가스는 흡입연결관(6)을 통해 흡입되어 압축기 내부로 흡입된다.Therefore, in the refrigeration cycle of the refrigerating system in which the piston 4 of the compressor unit 5 repeats the reciprocating motion in the cylinder 4a, the refrigerant gas is sucked through the suction connecting pipe 6 and sucked into the compressor.
이때 흡입되는 냉매가스의 온도가 압축기 내부 온도보다 낮기 때문에 바로 밑에 있는 방열판(15)을 냉각하게 된다.At this time, since the temperature of the refrigerant gas sucked is lower than the temperature inside the compressor, the heat sink 15 directly below is cooled.
냉각되는 방열판(15)으로 인해 밀폐 열전도관(16)은 열이 균일화되고 이 밀폐 열전도관(16)에 의해서 흡입관(12)이 냉각되어진다.Due to the heat dissipation plate 15 being cooled, the sealed heat conductive tube 16 is uniform in heat and the suction tube 12 is cooled by the sealed heat conductive tube 16.
따라서 압축기 본체의 흡입관(12)을 통해 실린더헤드(13)및 실린더(11)로 흡입되는 냉매가스는 압축기 내부의 고온 분위기 보다 훨씬 낮은 상태로 흡입되어서, 냉매특성의 밀도가 높아져서 운전 및 냉동효율이 좋아지는 효과가 있으며, 흡입관(12)이 밀폐 열전도관(16)에 용접으로 고정되어 있기 때문에 흡입맥동에 의한 파이프 고유진동수가 변화 되어 소음의 경감효과가 있다.Therefore, the refrigerant gas sucked into the cylinder head 13 and the cylinder 11 through the suction pipe 12 of the compressor main body is sucked in a state much lower than the high temperature atmosphere inside the compressor, so that the density of the refrigerant characteristics is high, so that the operation and refrigeration efficiency is increased. There is a better effect, because the suction pipe 12 is fixed to the sealed heat conducting pipe 16 by welding, the natural frequency of the pipe due to the suction pulsation is changed, thereby reducing the noise.
이상에서와 같이 본 고안은 냉동시스템에서 흡입된 냉매 가스를 곧바로 흡입하지 않고 방열판을 냉각시키면서 흡입될때 방열판과 냉매에 의한 열전도관의 흡입관 냉각작용으로 냉매가스가 저온이 되게 하여 이를 실린더 내부로 흡입시켜서 냉동특성을 높혀 효율의 상승과 흡입관의 흡입소음의 현저한 경감으로 제품의 기능 및 품질을 고급화 시킬 수 있는 것이다.As described above, the present invention does not directly inhale the refrigerant gas sucked from the refrigeration system, but cools the heat sink, so that the refrigerant gas is cooled to a low temperature by the suction pipe cooling action of the heat conduction pipe by the heat sink and the refrigerant, and sucks it into the cylinder. It is possible to upgrade the function and quality of the product by increasing the refrigeration characteristics and increasing efficiency and remarkably reducing the suction noise of the suction pipe.
