Description

스크롤 압축기의 냉각구조Cooling structure of scroll compressor

본 고안은 스크롤 압축기에 있어서, 냉매의 흐름을 조절하여 모터의 온도상승억제 및 스크롤 압축기의 체적효율을 개선하여 스크롤 압축기의 압축냉각 효율을 향상시키고자 한 스크롤 압축기의 냉각구조에 관한 것이다.The present invention relates to a cooling structure of a scroll compressor in the scroll compressor, by controlling the flow of the refrigerant to suppress the temperature rise of the motor and improve the volumetric efficiency of the scroll compressor to improve the compression cooling efficiency of the scroll compressor.

먼저, 종래 일반적인 스크롤 압축기의 구조에 대하여 제1도를 참조하여 설명하면 다음과 같다.First, the structure of a conventional general scroll compressor will be described with reference to FIG.

흡입 포트(Port)(1)을 통하여 저온, 저압의 냉매가 스크롤 압축기의 내부로 유입되어지게 된다.Low-temperature, low-pressure refrigerant is introduced into the scroll compressor through the suction port (1).

상기의 유입된 저온, 저압의 냉매는 모터(2)의 회전에 의한 선회 스크롤(3)이 구동으로 스테이터(Stator)(5)를 거쳐 고온, 고압의 냉매로 변환되어 토출 포트(4)를 통하여 응축기로 전달된다.The introduced low-temperature and low-pressure refrigerant is converted into a high-temperature and high-pressure refrigerant through the stator 5 by the turning scroll 3 driven by the rotation of the motor 2, and then through the discharge port 4. Delivered to the condenser.

미 설명부호 6은 권선 엔드-턴(End-Turn)부, 7은 고정 스크롤이다.Reference numeral 6 is a winding end-turn portion, and 7 is a fixed scroll.

이 때, 일반적인 스크롤 압축기의 압축효율(EER)은 다음의 수학식 1과 같이 나타낼 수 있게 된다.At this time, the compression efficiency (EER) of the general scroll compressor can be expressed by the following equation (1).

상기의 수학식 2와 수학식 3을 수학식 1에 대입하여 스크롤 압축기의 압축효율(EER)을 구할 수 있게 되는데, 여기서, Po는 이론동력, nv는 체적효율, ni는 압축효율, nm은 기계효율이며, 그리고 h1은 증발기 입구의 냉매 엔탈피(㎉/㎏), h2는 증발기 출구의 냉매 엔탈피(㎉/㎏), nmotor는 모터의 효율임을 나타내는 것이다.Substituting Equation 2 and Equation 3 into Equation 1, the compression efficiency (EER) of the scroll compressor can be obtained, wherein P o is the theoretical power, n v is the volumetric efficiency, n i is the compression efficiency, n m is the mechanical efficiency, h1 is the refrigerant enthalpy (㎉ / ㎏) at the inlet of the evaporator, h2 is the refrigerant enthalpy (㎉ / ㎏) at the outlet of the evaporator, and n motor is the efficiency of the motor.

그럼므로, 압축기의 압축효율(EER)을 향상시키기 위해서는 냉매능력 및 각종 효율을 상승시킴으로 가능하게 되는 것이다.Therefore, in order to improve the compression efficiency (EER) of the compressor, it is possible to increase the refrigerant capacity and various efficiency.

따라서, 본 고안은 스크롤 압축기 내부 냉매의 흐름을 통하여 모터 권선의 엔드-턴부분에 대한 냉각이 적절하도록 권선의 온도상승을 억제하여 모터의 동손부분을 저감시켜 주므로서, 냉동능력 및 각종 효율을 상승시켜 전체적인 압축기의 냉각효율을 향상시키고자 한 것으로 종래와 동일부호에 대하여서는 동일부호로 처리하여 설명하면 다음과 같다.Accordingly, the present invention reduces the copper loss of the motor by suppressing the temperature rise of the winding so that the cooling of the end-turn portion of the motor winding is appropriate through the flow of the refrigerant inside the scroll compressor, thereby increasing the refrigerating capacity and various efficiency. In order to improve the cooling efficiency of the compressor as a whole, the same reference numerals are used to describe the same reference numerals as before.

본 고안 스크롤 압축기의 냉각구조는 제2도와 제3도에 도시된 바와 같이, 흡입 포트(1)을 통하여 압축기의 내부로 유입되어진 저온, 저압의 냉매를 선회 스크롤(3)의 구동에 의하여 스테이터(5)를 거쳐 고온, 고압의 냉매로 변환되어 토출 포트(4)로 토출되도록 하는 스크롤 압축기에 있어서, 냉매의 흐름(10)을 조절할 수 있도록 하는 냉매 차폐부(8)를 스크롤 압축기의 하단에 장착하여 권선 엔드-턴부(6)의 내, 외측면을 냉각시키도록 이루어져 있다.As shown in FIG. 2 and FIG. 3, the cooling structure of the present invention scroll compressor uses a low-temperature, low-pressure refrigerant introduced into the compressor through the suction port 1 to drive the stator (3). In the scroll compressor that is converted to a high temperature, high pressure refrigerant through 5) to be discharged to the discharge port (4), a refrigerant shield (8) for controlling the flow of the refrigerant (10) is mounted at the bottom of the scroll compressor To cool the inner and outer surfaces of the winding end-turn portion 6.

그리고, 상기 냉매차폐부(8)에는 스크롤 압축기의 운전을 용이하게 하기 위한 오일(oil)의 통로(9)를 포함한 구성이다.The refrigerant shield 8 includes an oil passage 9 to facilitate the operation of the scroll compressor.

이와 같이 이루어지게 되는 본 고안 스크롤 압축기의 냉각구조는 스크롤 압축기의 하단에 장착된 냉매차폐부(8)에 의하여 냉매는 권선 엔드-턴부(6)의 내, 외측면으로 유도되어지게 된다.In the cooling structure of the present invention the scroll compressor is made as described above, the refrigerant is guided to the inner and outer surfaces of the winding end-turn part 6 by the refrigerant shielding portion 8 mounted at the bottom of the scroll compressor.

상기와 같이 냉매 차폐부(8)에 의해 유도되어진 냉매는 권선 엔드-턴부(6)의 내,외측면을 냉각시켜 주게 된다.The coolant guided by the coolant shielding part 8 as described above cools the inner and outer surfaces of the winding end-turn part 6.

이 때, 권선 엔드-턴부(6)의 냉각효과에 의하여 모터(2)의 권선 온도상승을 억제하게 되며, 이에 따라서 모터(2)의 손실중에서 대부분을 차지하게 되는 동손분을 저감시키게 된다.At this time, the increase in the winding temperature of the motor 2 is suppressed by the cooling effect of the winding end-turn part 6, thereby reducing the copper loss which occupies most of the loss of the motor 2.

여기서, 냉매 차폐부(8)에 포함된 오일의 통로(9)는 압축기의 윤활작용이 원활하게 수행되도록 하부에 저장된 오일(oil)을 상부의 크랭크축 및 베어링부(도시하지 않음)로 끌어올리는 역할을 수행한 후 그 오일이 재윤활 되어지도록 다시 하부 저장소로 모으는 통로 역할을 하여 압축기의 운전이 용이하도록 한다.Here, the passage 9 of the oil included in the refrigerant shield 8 lifts the oil stored in the lower portion to the upper crankshaft and the bearing portion (not shown) so as to smoothly perform the lubrication of the compressor. After performing the role, the oil acts as a passage for collecting oil back to the lower reservoir for relubrication, so that the compressor can be easily operated.

따라서, 모터(2)의 온도상승 억제로 인한 동손분을 저감시키게 되므로서, 모터(2)의 효율(nmotor)을 향상시키게 된다.Therefore, the copper loss due to the suppression of the temperature rise of the motor 2 is reduced, thereby improving the efficiency n motor of the motor 2.

또한, 압축기의 전체적인 온도상승 억제로 인하여 스크롤 압축기의 체적효율(nv)상승을 유발하게 되어 상기의 종래 기술에서 설명한 수학식 1,2,3에 의하여 모터(2)의 효율(nmotor) 상승 및 체적효율(nv)상승으로 인한 전체적인 스크롤 압축기의 냉각효율(EER)을 상승시키게 된다.In addition, due to the suppression of the overall temperature rise of the compressor, the volumetric efficiency (n v ) of the scroll compressor is caused to increase, so that the efficiency (n motor ) of the motor 2 is increased by the equations (1, 2, 3) described in the prior art. And it increases the cooling efficiency (EER) of the entire scroll compressor due to the increase in the volume efficiency (n v ).

이상에서 설명한 바와 같이, 압축기의 하단에 냉매의 흐름을 조절하도록 하는 냉매차폐부를 장착하여 냉매의 흐름을 조절하고 모터의 권선 엔드-턴부의 내,외측면을 냉각시켜 주도록 하므로서, 모터의 온동상승을 억제하여 전체적인 압축기 냉각효율을 향상시키는 효과가 있다.As described above, a coolant shielding part is installed at the lower end of the compressor to adjust the flow of the coolant, thereby controlling the flow of the coolant and cooling the inner and outer surfaces of the winding end-turn of the motor, thereby increasing the warm-up of the motor. Inhibition has the effect of improving the overall compressor cooling efficiency.
