본 고안은 스터어링 엔진에 관한 것으로, 좀더 구체적으로는 냉각기의 구조를 개선하여 작동 유체가 히트 파이프(Heat Pipe)에 의해 냉각되게 하고 작동유체의 냉각시 작동유체로부터 빼앗은 열로 연소기에 공급되는 공기를 가열시켜 엔진의 열 효율을 향상시킬 수 있도록 한 것이다.The present invention relates to a steering engine, and more specifically, to improve the structure of the cooler to allow the working fluid to be cooled by the heat pipe (Heat Pipe) and to cool the working fluid to the air supplied to the combustor by the heat taken from the working fluid The heating is to improve the thermal efficiency of the engine.
스터어링 엔진은 밀폐된 공간내의 기체를 가열시킬 때 기체의 압력이 상승하고 반대로 냉각시킬 때에는 압력이 하강하는 원리를 이용하여 피스턴과 같은 구동체를 연속적으로 구동시키는 기관이다.The steering engine is an engine that continuously drives a driving body such as a piston using the principle that the pressure of the gas rises when heating the gas in an enclosed space and the pressure decreases when cooling the gas.
종래에 사용되어온 스터어링 엔진은 제 3 도에 도시한 바와같이 연소실(1)의 일측에 축열기(Regenerator)(2)와 냉각기튜브(13)를 설치하고 일단이 축열기(2)에 연결된 히터튜브(4)를 연소실(1) 내부로 노출되게 함과 함께 히터튜브(4)의 다른 일단은 실린더(3)에 연결하며, 냉각기튜브(13)의 주위에 쉘(shell)을 설치한 구조로 되어 있다.Conventionally used steering engines have a regenerator (2) and a cooler tube (13) installed on one side of the combustion chamber (1) and one end connected to the regenerator (2), as shown in FIG. The tube 4 is exposed to the inside of the combustion chamber 1, and the other end of the heater tube 4 is connected to the cylinder 3, and a shell is installed around the cooler tube 13. It is.
또 실린더(3)내에는 피스턴헤드(5)와 피스턴(6)을 설치하여 실린더(3)의 내부 공간을 압축실(A)과 팽창실(B)로 구획하고 있다.In addition, the piston 3 is provided with the piston head 5 and the piston 6, and the internal space of the cylinder 3 is divided into the compression chamber A and the expansion chamber B. As shown in FIG.
따라서 튜브내의 작동 유체가 압축실(A)로부터 냉각기튜브(13)와 축열기(2)를 거쳐 히터튜브(4)를 지나는 동안에는 연소실(1)의 열을 받아 작동유체에 압력이 증가하고 이 증가된 압력은 피스턴 헤드(5)에 작용하여 피스턴(6)을 하강시키게 되며, 반대로 작동유체가 팽창실(B)로부터 축열기(2)를 지나 냉각기튜브(13)를 통과할 때에는 작동유체가 냉각되면서 압력이 감소되고, 이에 따라 피스턴(6)은 상승하게 된다.Therefore, while the working fluid in the tube passes from the compression chamber (A) through the cooler tube (13) and the regenerator (2) and passes through the heater tube (4), the pressure in the working fluid increases due to the heat of the combustion chamber (1). The applied pressure acts on the piston head 5 to lower the piston 6. On the contrary, when the working fluid passes from the expansion chamber B through the regenerator 2 and passes through the cooler tube 13, the working fluid is cooled. As the pressure decreases, the piston 6 rises.
여기서 냉각기는 쉘과 튜브의 열교환 방식으로 된 냉각기가 이용되었으며, 냉각기 튜브로는 작동유체가 통과하고 쉘측으로는 냉각수가 흐르게 하여 냉각기 튜브내를 흐르는 작동유체를 냉각시킨다.Here, the cooler is a heat exchanger of the shell and tube was used, the working fluid passes through the cooler tube and the cooling water flows to the shell side to cool the working fluid flowing in the cooler tube.
그러나 상기한 종래의 스터어링 엔진은 냉각기가 쉘과 튜브의 열교환방식이어서 엔진이 운전되는 동안에는 항상 냉각수가 공급되어야 하므로 수원이 없는 지역에서는 냉각수의 공급에 어려움이 많아 사용상의 제약을 받게 된다.However, the conventional steering engine is a heat exchange method between the shell and the tube so that the coolant must be supplied at all times while the engine is operating.
또한 냉각수는 쉘측으로 흐르는 동안 작동유체로부터 열을 빼앗아 온수화되므로 열매체로 재 활용할 수 있지만 냉각수의 열손실은 회수가 불가능하여 엔진의 열 효율이 떨어진다.In addition, the cooling water takes the heat from the working fluid while flowing to the shell side, so that it can be reused as a heat medium, but the heat loss of the cooling water is impossible to recover, which lowers the engine's thermal efficiency.
스터어링 엔진에서 발생되는 냉각수의 열 손실은 일반적으로 열 공급량의 30-40%정도가 되는 것이어서 열손실은 막대하다.The heat loss of the coolant generated by the steering engine is generally about 30-40% of the heat supply, so the heat loss is enormous.
본 고안의 목적은 별도의 냉각수 공급이 필요하지 않고, 또한 냉각기에서 흡수한 열로 연소공기를 예열할 수 있는 개선된 냉각기 구조를 제공하기 위한 것인바, 이를 첨부된 도면 제 1 도 및 제 2 도에 의해 더욱 상세히 설명하면 다음과 같다.It is an object of the present invention to provide an improved cooler structure that does not require a separate coolant supply and can also preheat combustion air with heat absorbed by the cooler, as shown in FIGS. 1 and 2. When described in more detail as follows.
연소실(1)의 일측에 축열기(2)를 설치하여 이 축열기(2)와 실린더(3) 사이에 히터튜브(4)를 연결하고 실린더(3) 내에는 피스턴헤드(5)와 피스턴(6)을 설치하여 실린더 내부공간이 압축실(A)과 팽창실(B)로 구획되도록 한 스터어링 엔진에 있어서, 축열기(2)와 압축실(A)사이에 설치되는 냉각기를 냉각수가 충진된 쉘(7)과 상기 쉘의 바깥측에 동심원상으로 배열된 냉각관(8)의 2중관으로 형성하고 쉘(7) 내부에 다수의 냉각기 튜브(9)를 설치하며 쉘(7)에는 쉘의 내부와 외부를 방사상으로 관통하는 다수의 히트파이프(10)를 핀 형태로 설치하여서 된 것이다.A heat accumulator 2 is installed on one side of the combustion chamber 1 to connect the heater tube 4 between the heat accumulator 2 and the cylinder 3, and the piston head 5 and the piston in the cylinder 3. 6) A steering engine in which a cylinder inner space is partitioned into a compression chamber (A) and an expansion chamber (B) by installing a coolant filled with coolant installed between the heat storage unit (2) and the compression chamber (A). Shell (7) and a double tube of cooling tubes (8) arranged concentrically on the outside of the shell, and a plurality of cooler tubes (9) are installed inside the shell (7), and the shell (7) is a shell It is made by installing a plurality of heat pipes 10 that penetrate radially through the inside and outside of the fin form.
도면중 미설명부호 11은 냉각관과 연결된 연결관, 12는 공기예열기이다.In the figure, reference numeral 11 denotes a connecting tube connected to a cooling tube, and 12 denotes an air preheater.
이와 같이 구성된 본 고안은 엔진의 구동에 따라 냉각기튜브(9) 내로 작동유체가 흐르면 쉘(7)내에 충진된 냉각수가 작동유체를 냉각시키게 되고 냉각수는 작동유체와의 열교환에 의해 가열되며, 가열된 냉각수는 쉘(7)을 관통하는 다수의 히트파이프(10)를 통해 냉각관(9\8)으로 흐르는 냉각공기와 열교환을 하면서 냉각공기를 가열시키과 동시에 히트파이프(10)는 냉각된다.When the working fluid flows into the cooler tube 9 according to the driving of the engine, the present invention configured as described above cools the working fluid with the cooling water filled in the shell 7 and the cooling water is heated by heat exchange with the working fluid. The cooling water heats the cooling air while performing heat exchange with the cooling air flowing through the plurality of heat pipes 10 passing through the shell 7 to the cooling tube 9 \ 8, and at the same time, the heat pipe 10 is cooled.
따라서 냉각기튜브(9) 내로 흐르는 작동유체를 계속해서 냉각시키게 되며, 가열된 냉각공기는 연결관(11)을 통해 공기예열기(12)로 공급되어 연소실(1)의 연소 효율을 높이게 된다.Therefore, the working fluid flowing into the cooler tube 9 is continuously cooled, and the heated cooling air is supplied to the air preheater 12 through the connection pipe 11 to increase the combustion efficiency of the combustion chamber 1.
또 본 고안에 사용되는 히트파이프(10)는 ㅇ녈교환 장치에 널리 응용되는 것으로, 이 히트파이프의 열유속은 히트파이프 내의 작동유체가 메탄올 일때 축방향으로 0.45kw/cm2이고 표면에서 75.5w/cm2이므로 본 고안과 같은 냉각기에 적용하는 경우 냉각기 튜브(9)내로 흐르는 작동유체를 쉘(7)내부에 충진되어 있는 냉각수로 1차 냉각시키고 작동유체와의 열교환에 의해 가열된 냉각수를 히트파이프(10)를 통해 공기로 2차 냉각시켜 충분한 냉각능력을 발휘할 수 있게 된다.In addition, the heat pipe 10 used in the present invention is widely applied to a heat exchanger, and the heat flux of the heat pipe is 0.45kw / cm 2 in the axial direction when the working fluid in the heat pipe is methanol and 75.5w / cm at the surface. 2 because the pipe for the case of applying to the condenser, such as the subject innovation primary cooling a working fluid flowing into the condenser tube 9 to the cooling water that is filled in the inner shell (7) is heated by heat exchange with the working fluid cooling water heat ( 10) through secondary cooling with air to achieve a sufficient cooling capacity.
이상에서와 같이 본 고안은 냉각수의 순환이 필요하지 않고 이에 따라 냉각수의 계속적인 공급이 불필요해지므로 냉각수의 공급을 위한 관로 등의 부속 장치가 삭제되어 엔진의 형상을 단순화 할 수 있게 됨은 물론 물이 없는 지역에서도 사용이 가능해진다.As described above, the present invention does not require the circulation of the cooling water, and thus, the continuous supply of the cooling water is unnecessary, thereby eliminating accessories such as a pipeline for supplying the cooling water, thereby simplifying the shape of the engine, as well as water. It can be used even in areas that are not available
또 종래의 스터어링 엔진에서는 냉각수의 열손실을 회수할 수 없었지만 본 고안에서는 공기를 냉각용 열매체로 사용함에 따라 작동유체로 부터 빼앗은 열을 공기에 전달하여 작동유체의 냉각은 물론 가열된 공기를 연소실에 공급하게 되어 있으므로 엔진의 열효율을 증대시킬 수 있게 되며, 연결관의 출구측을 직접 난방이 필요한 곳에 연결하여 가열공기를 난방용으로 사용할 수도 있게 된다.In addition, in the conventional steering engine, the heat loss of the cooling water could not be recovered, but according to the present invention, as air is used as the cooling medium, the heat taken from the working fluid is transferred to the air, thereby cooling the working fluid and heating the heated air. Since it is possible to supply to the heat efficiency of the engine can be increased, and the outlet side of the connecting pipe can be directly connected to the place where the heating is required to use the heating air for heating.
