Description

밀폐형 압축기의 방열구조Heat dissipation structure of hermetic compressor

본 고안은 냉장고 등에 설치되어 밀폐된 케이스 내에서 냉매가스를 흡입하여 압축 및 토출시켜 주는 밀폐형 압축기에 관한 것이다.The present invention relates to a hermetic compressor installed in a refrigerator or the like to inhale and compress and discharge refrigerant gas in a sealed case.

더욱 상세하게는, 압축기의 케이스 형상을 변경하여 내부에서 발생하는 열을 방출시키기에 용이하도록 한 밀폐형 압축기의 방열구조에 관한 것이다.More specifically, the present invention relates to a heat dissipation structure of a hermetic compressor, which makes it easy to change the case shape of the compressor to release heat generated therein.

일반적으로 압축기는 기계적인 에너지를 압축성 유체의 압축에너지로 변환시켜 주는 기기로서, 그 종류로는 왕복압축기, 회전압축기, 터보압축기 등이 있다.In general, a compressor is a device that converts mechanical energy into compressive energy of a compressive fluid, and examples thereof include a reciprocating compressor, a rotary compressor, and a turbo compressor.

왕복압축기는 피스톤의 왕복운동을 통해서 냉매가스를 압축시켜 주고, 회전압축기는 실린더 내의 회전자를 회전시켜 냉매가스를 압축하며, 터보압축기는 임펠러의 원심력을 이용하여 속도에너지를 압력에너지로 변환시켜 냉매가스를 압축시켜 준다.The reciprocating compressor compresses the refrigerant gas through the reciprocating motion of the piston, and the rotary compressor compresses the refrigerant gas by rotating the rotor in the cylinder.The turbo compressor converts the velocity energy into pressure energy by using the centrifugal force of the impeller. Compress the gas.

이러한 압축기는 증발기로 부터 유입된 저압의 냉매가스를 압축하여 응축압력 까지 높여주는 역할을 한다.Such a compressor serves to increase the condensation pressure by compressing the low pressure refrigerant gas introduced from the evaporator.

그리고, 압축기로 부터 토출된 냉매가스는 응축기, 팽창밸브, 증발기 등을 순환하면서 냉매가스의 증발잠열을 이용하여 증발기 주위의 열을 빼앗는 냉각작용을 하게 된다.In addition, the refrigerant gas discharged from the compressor circulates through the condenser, the expansion valve, and the evaporator, thereby performing a cooling operation to take heat around the evaporator using the latent heat of evaporation of the refrigerant gas.

즉, 압축기가 냉매가스를 압축하여 포화압력 까지 압력과 온도를 상승시켜 주면, 응축기가 물이나 공기를 이용하여 고온ㆍ고압의 냉매가스가 갖고 있는 열을 흡수하므로서 냉매가스를 응축 및 액화시키고, 응축 및 액화된 냉매가스는 팽창밸브의 교축작용에 의해 온도와 압력이 급격히 낮아지며, 이 냉매가스가 증발기에서 증발되면서 피냉각물체로 부터 열을 흡수하여 냉각시키게 되는 것이다.In other words, when the compressor compresses the refrigerant gas and raises the pressure and temperature up to the saturation pressure, the condenser absorbs heat contained in the refrigerant gas of high temperature and high pressure by using water or air to condense and liquefy the refrigerant gas. And the liquefied refrigerant gas is rapidly lowered in temperature and pressure by the throttling action of the expansion valve, and the refrigerant gas is cooled by absorbing heat from the object to be cooled as it is evaporated in the evaporator.

도 1은 일반적인 밀폐형 압축기를 나타낸 단면도로서, 밀폐형 압축기는 용접에 의해 밀폐된 상하부케이스(10,20) 내에 압축기 본체가 내장되어 있다.1 is a cross-sectional view showing a general hermetic compressor, the hermetic compressor is built in the upper and lower case (10, 20) sealed by welding.

압축기 본체는 크게 골격 역할을 하는 프레임(30)과, 이 프레임의 하부에 설치되어 전동매체인 샤프트(60)를 회전시켜 주는 구동부(또는 모터부,40) 및, 상기 샤프트의 회전운동을 직선운동으로 변환하여 흡입된 냉매가스를 압축 및 토출시켜 주는 기계부(50)로 구성되어 있다.The compressor main body has a frame 30 that acts as a skeleton, a drive unit (or motor unit 40) installed at the lower part of the frame to rotate the shaft 60, which is a transmission medium, and linear movement of the rotational movement of the shaft. It consists of a mechanical unit 50 for compressing and discharging the refrigerant gas sucked by the conversion.

상기 프레임(30)은 구동부와 기계부 전체를 지지하며, 그 자신은 상하부케이스(10,20)에 각각 완충 및 소음방지수단인 사이드 스토퍼(70)와 코일스프링(80)을 통하여 지지된다.The frame 30 supports the entire driving part and the mechanical part, and is supported by the upper and lower cases 10 and 20 through side stoppers 70 and coil springs 80 which are cushioning and noise preventing means, respectively.

상기 구동부(40)는 프레임에 지지되어 고정자 역할을 하는 스테이터(90) 및, 샤프트(60)를 회전시켜 주는 로터(100)로 구성된다.The drive unit 40 is composed of a stator 90 supported by the frame to serve as a stator, and a rotor 100 to rotate the shaft 60.

상기 기계부(50)는 프레임 상단에 고정되는 실린더(110)와, 상기 실린더에 삽입되는 피스톤(120) 및, 상기 피스톤과 샤프트(60)의 크랭크부(61) 사이에 연결되어 샤프트의 회전운동을 직선운동으로 변환시켜 주는 피스톤로드(130)로 구성된다.The mechanical part 50 is connected between the cylinder 110 fixed to the upper end of the frame, the piston 120 inserted into the cylinder, and the crank part 61 of the piston and the shaft 60 to rotate the shaft It consists of a piston rod 130 that converts to a linear motion.

상기 기계부는 피스톤로드에 의해 피스톤이 실린더 내에서 직선 왕복운동을 하면서 흡입밸브를 통하여 흡입된 냉매가스를 실린더 내에서 압축한 뒤 토출밸브를 통하여 토출시켜 주며, 흡입 및 토출머플러는 흡입 또는 토출되는 냉매가스를 안내하게 된다.The mechanical unit compresses the refrigerant gas sucked through the intake valve through the intake valve and discharges it through the discharge valve while the piston is linearly reciprocated in the cylinder by the piston rod, and the suction and discharge muffler is the refrigerant sucked or discharged. Guide the gas.

따라서, 이러한 압축기는 구동부(40)에 의해 회전하는 샤프트(60)가 기계부(50)의 피스톤로드(130)를 왕복 운동시키므로서 상기 피스톤로드에 의해 피스톤(120)이 실린더(110) 내에서 직선 왕복운동을 하면서 실린더 내로 흡입된 냉매가스를 압축 및 토출시켜 주고, 이 냉매가스는 냉동장치를 순환하므로서 소기의 냉동 목적을 달성하게 된다.Thus, such a compressor has a piston (120) in the cylinder (110) by the piston rod as the shaft 60 rotated by the drive unit 40 reciprocates the piston rod (130) of the mechanical part (50). The refrigerant gas sucked into the cylinder is compressed and discharged in a linear reciprocating motion, and the refrigerant gas circulates through the refrigeration apparatus, thereby achieving the desired refrigeration purpose.

한편, 압축기는 냉매가스를 흡입하여 압축 및 토출시키는 과정에서 구동부(40)의 손실열(동손+철손), 냉매가스의 압축열, 기계부(50)의 접촉열(마찰열) 등이 발생하는데, 이들 열로 인해 내부가 과열되면 압축기의 수명에 치명적인 해를 끼친다.On the other hand, the compressor generates a loss heat (copper loss + iron loss) of the drive unit 40, the compression heat of the refrigerant gas, the contact heat (friction heat) of the mechanical unit 50 in the process of inhaling the compressed and discharged refrigerant gas, Overheating due to these heats can seriously damage the life of the compressor.

예를 들어, 구동부(40) 내의 손실열이 증가하게 되면 냉매가스가 과열되어 압축열이 증가하고, 압축열이 증가하면 냉각성능이 떨어질 뿐만 아니라 내부환경이 고온으로 되기 때문에 냉동기유 및 구동부에 설치된 절연물의 노화를 촉진하여 압축기의 수명을 단축시키게 된다.For example, if the loss heat in the drive unit 40 increases, the refrigerant gas is overheated to increase the heat of compression, and if the heat of compression increases, the cooling performance is lowered and the internal environment becomes high. This accelerates the aging of the insulation and shortens the life of the compressor.

도 2는 종래 압축기의 외관을 나타낸 정면도이다.2 is a front view showing the appearance of a conventional compressor.

도시한 바와 같이 종래의 압축기는 철재로 된 상하부케이스(10,20)를 반구형태로 절곡 성형하여 용접으로 밀폐시켰던 것이다.As shown in the figure, the conventional compressor was formed by bending the upper and lower cases 10 and 20 made of steel in a hemispherical shape and sealing them by welding.

따라서, 이와 같은 압축기는 내부에서 순환하는 냉동기유 및 상기 상하부케이스의 표면과 접촉하는 외기 외에는 내부에서 발생하는 열을 방출시켜 주는 수단이 없었다.Therefore, such a compressor had no means for releasing heat generated therein except for the refrigeration oil circulating therein and the outside air contacting the surfaces of the upper and lower cases.

더욱이, 상하부케이스의 표면이 단조롭기 때문에 외기와의 접촉면적이 넓지 않아 방열면적이 작고, 이로 인해 열 방출량이 적기 때문에 온도상승을 유발하는 문제점이 있었던 것이다.In addition, the surface of the upper and lower casing is monotonous, so the contact area with the outside air is not wide, and thus the heat dissipation area is small, which causes a rise in temperature because of a small amount of heat emission.

본 고안은 이러한 문제점을 해결하기 위하여 안출한 것으로 그 기술적인 과제는 압축기를 구성하는 상부케이스의 구조를 개선하여 방열효과가 뛰어나도록 한 것이다.The present invention has been made to solve this problem, the technical problem is to improve the structure of the upper case constituting the compressor to be excellent heat dissipation effect.

상기의 과제를 달성하기 위하여 본 고안은 압축기의 상부케이스에 다수의 냉각핀을 주름진 형태로 형성하여 외기와의 접촉면적을 넓혀준 것이다.In order to achieve the above object, the present invention broadens the contact area with outside air by forming a plurality of cooling fins in a corrugated form in the upper case of the compressor.

상기와 같이 구성된 본 고안은 다수의 냉각핀에 의해 외기와의 접열면적이 넓어지므로서 열 방출효과가 뛰어난 효과가 있다.The present invention configured as described above has an effect of excellent heat dissipation effect by widening the contact area with the outside air by a plurality of cooling fins.

이하에서 본 고안을 첨부된 도면에 의거 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 3과 도 4는 본 고안에 따른 압축기의 외관을 나타낸 정면도와 평면도이고, 도 5는 상부케이스의 단면도를 나타낸 것이다.3 and 4 are a front view and a plan view showing the appearance of the compressor according to the present invention, Figure 5 shows a cross-sectional view of the upper case.

도시한 바와 같이 본 고안은 상하부케이스(10,20)가 용접에 의해 밀폐되는 통상의 밀폐형 압축기에 있어서,As shown in the present invention in the conventional hermetic compressor in which the upper and lower cases 10 and 20 are sealed by welding,

상기 상부케이스(10)의 주연에 다수의 냉각핀(11)을 일체로 돌출 성형하여서 된 것이다.A plurality of cooling fins 11 are formed by integrally protruding the peripheral part of the upper case 10.

상기 냉각핀(11)은 상부케이스(10)의 전 둘레에 걸쳐 일정한 간격으로 형성된다.The cooling fins 11 are formed at regular intervals over the entire circumference of the upper case 10.

상기와 같이 구성된 본 고안은 다수의 냉각핀(11)에 의해 상부케이스(10)의 표면적이 늘어나게 되어 그만큼 외기와의 접촉면적이 넓어진다.According to the present invention configured as described above, the surface area of the upper case 10 is increased by the plurality of cooling fins 11, and thus the contact area with the outside air is increased.

따라서, 상부케이스(10)를 통하여 방출되는 열량도 많게 되어 상대적으로 압축기 내부의 냉동기유 및 냉매의 온도가 낮아지는 방열효과를 얻을수 있다.Therefore, the amount of heat discharged through the upper case 10 also increases, so that the heat dissipation effect of lowering the temperature of the refrigerant oil and the refrigerant in the compressor can be obtained.

결국, 상부케이스에 형성된 다수의 냉각핀에 의해 외기와의 접열면적이 넓어져 열 방출효과가 뛰어난 것이다.As a result, the contact area with the outside air is widened by a plurality of cooling fins formed in the upper case, and the heat dissipation effect is excellent.

이상에서 설명한 바와 같이 본 고안은 압축기의 상부케이스에 다수의 냉각핀을 일체로 형성하여 외기와의 접촉면적을 넓혀 주므로서 열 방출효과가 뛰어나 압축기의 수명을 연장시키고, 냉각능력 및 신뢰성 향상에 기여할수 있는 것이다.As described above, the present invention forms a large number of cooling fins integrally with the upper case of the compressor, thereby widening the contact area with the outside air, thereby improving heat dissipation effect and extending the life of the compressor, and contributing to the improvement of cooling capacity and reliability. It can be.
