Description

맥동관 냉동기{PULSE TUBE REFRIGERATOR}Pulse Tube Refrigerator {PULSE TUBE REFRIGERATOR}

본 발명은 맥동관 냉동기에 관한 것으로, 특히 재생기와 맥동관이 나란하게 배치되는 유(U)타입의 맥동관 냉동기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pulsating tube freezer, and more particularly, to an oil type (U) pulsating tube refrigerator in which a regenerator and a pulsating tube are arranged side by side.

일반적으로 극저온 냉동기는 소형 전자부품이나 초전도체 등의 냉각을 위하여 사용되는 저진동 고신뢰성의 냉동기로서, 주로 스터링 냉동기(Stirling Refrigerator)나 지엠 냉동기(GM Refrigerator) 또는 줄-톰슨 냉동기(Joule-Thomson Refrigerator) 등이 널리 알려져 있으나, 이러한 냉동기들은 고속운전시 그 신뢰성이 저하되므로 최근에는 고속운전에서도 신뢰성이 유지되는 맥동관 냉동기가 새롭게 각광받고 있다.In general, cryogenic freezer is a low vibration high reliability freezer used for cooling small electronic parts or superconductor, mainly Stirling Refrigerator, GM Refrigerator or Joule-Thomson Refrigerator. Although it is widely known, these refrigerators have been deteriorated in reliability at high speed, and thus, recently, a pulsating tube refrigerator having high reliability in high speed operation has been in the spotlight.

상기 맥동관 냉동기는 작동가스가 펌핑되는 압축유니트와, 그 압축유니트에 의해 펌핑되면서 관내를 왕복운동 하는 작동가스의 열역학적 사이클에 의해 극저온부를 갖게 되는 냉동유니트로 크게 이루어져 있다. 이 중에서 냉동유니트는 압축유니트의 출구측에 재생기(예냉기가 재생기 앞에 구비된 경우도 있음), 맥동관, 위상제어기 그리고 저장용기가 연이어 연통 배치되고, 상기 재생기와 맥동관 사이에는 냉측열교환기가 장착되는 반면 상기 맥동관과 위상제어기 사이에는 온측열교환기가 장착되어 이루어져 있다.The pulsating tube refrigeration machine is largely composed of a compression unit in which a working gas is pumped, and a refrigeration unit having a cryogenic portion by a thermodynamic cycle of a working gas reciprocating in the tube while being pumped by the compression unit. Among them, the refrigerating unit is arranged in communication with a regenerator (sometimes, a precooler may be provided in front of the regenerator), a pulsating tube, a phase controller, and a storage container in series with each other, and a cold side heat exchanger is installed between the regenerator and the pulsating tube. On the other hand, an on-side heat exchanger is mounted between the pulsating tube and the phase controller.

상기 재생기에서 저장용기까지가 일렬로 배치되는 타입을 편의상 인라인 타입의 맥동관 냉동기라고 하는 반면 상기 재생기와 맥동관 사이가 절곡되어 서로 나란하게 배치되는 타입을 편의상 유(U) 타입 맥동관 냉동기라고 구분하고 있다.The type from which the regenerator to the storage container is arranged in a line is called an inline type pulsating tube freezer for convenience, while the type in which the regenerator and the pulsating tube are bent and arranged in parallel with each other is classified as a U type pulsating tube freezer for convenience. Doing.

상기 인라인 타입 맥동관 냉동기든 유 타입 맥동관 냉동기든 그 작동과정은 동일한데, 먼저 압축유니트의 압축행정시 작동가스는 압축되었다가 재생기를 거치면서 현열을 빼앗긴 상태로 냉측열교환기를 통해 맥동관으로 유입되어 그 맥동관에 채워져 있던 작동가스를 온측열교환기쪽으로 밀어내게 되고, 이 온측열교환기쪽으로 밀려나는 작동가스는 오리피스를 거쳐 저장용기로 유입되면서 단열압축되어 방열된다. 이때, 상기 맥동관으로 유입되는 작동가스의 질량유량이 오리피스를 통해 유출되는 작동가스의 질량유량보다 상대적으로 많으므로 맥동관은 고압에서의 열적평형상태를 이루게 된다.The operation process is the same for the inline type pulsating tube freezer or the U type pulsating tube freezer. The operating gas is first compressed during the compression stroke of the compression unit and then passed through the regenerator and deprived of sensible heat. Then, the working gas filled in the pulsating tube is pushed toward the on-side heat exchanger, and the working gas pushed toward the on-side heat exchanger passes through the orifice and enters into the storage container to be insulated and radiated. At this time, since the mass flow rate of the working gas flowing into the pulsating tube is relatively larger than the mass flow rate of the working gas flowing out through the orifice, the pulsating tube achieves a thermal equilibrium at high pressure.

이후, 상기 압축유니트의 흡입행정시 맥동관으로 유입되었던 작동가스가 다시 냉측열교환기 및 재생기를 거치면서 최초상태로 회복되어 반출되는 반면, 상기 맥동관에서는 그 맥동관으로부터 반출되는 작동가스의 질량유량이 오리피스를 통해 맥동관으로 반입되는 작동유량 보다 상대적으로 많아 결국 맥동관에서의 작동가스는 단열 팽창된다. 이 작동가스의 단열팽창은 통상 냉측열교환기쪽에서 급격하게 발생되어 그 냉측열교환기에서 극저온부가 형성된다.Thereafter, the working gas introduced into the pulsation tube during the suction stroke of the compression unit is returned to the initial state through the cold side heat exchanger and the regenerator, and then discharged. In the pulsating tube, the mass flow rate of the working gas carried out from the pulsation tube is discharged. The working gas in the pulsating tube is adiabaticly expanded because the working flow into the pulsating tube is relatively higher than that brought into the pulsating tube through the orifice. The adiabatic expansion of this working gas usually occurs abruptly on the cold side heat exchanger to form the cryogenic portion in the cold side heat exchanger.

이후, 상기 맥동관은 저압상태의 열적평형상태를 이루게 되는데, 이 과정에서 작동가스는 지속적으로 오리피스를 통해 저장용기에서 맥동관으로 이동하면서 맥동관내 작동가스의 압력을 높여 맥동관내의 온도를 처음의 온도로 회복시키게 된다.Thereafter, the pulsating tube is in a low pressure thermal equilibrium state, in which the working gas is continuously moved from the storage vessel to the pulsating tube through the orifice to increase the pressure of the working gas in the pulsating tube to increase the temperature in the pulsating tube. It will recover to temperature.

이러한 일련의 과정을 반복하면서 상기한 냉측열교환기에서는 점점 낮은 극저온부가 형성되는 것이었다.By repeating this series of processes, the cryogenic heat exchanger was formed with an increasingly low cryogenic portion.

한편, 상기 U타입의 맥동관 냉동기는 도 1에 도시된 바와 같이, 예냉기(1)의 냉동유니트쪽 측면에 재생기(2)와 맥동관(3)이 각각 나란하게 배치되어 삽입되고, 그 재생기(2)의 끝단에는 제1 냉측열교환기(4A)가 장착되며, 상기 맥동관(3)의 시작단에는 제2 냉측열교환기(4B)가 장착되고, 상기 제1 냉측열교환기(4A)의 끝단면과 제2 냉측열교환기(4B)의 시작단면은 그 각 냉측열교환기(4A,4B)를 연통시키는 연결관(5)의 양끝단이 각각 장착되어 있다. 도면중 미설명 부호인 6은 온측열교환기, 7은 위상제어기, 8은 저장용기이다.On the other hand, as shown in Figure 1, the U-type pulsating tube refrigerator, the regenerator 2 and the pulsating tube (3) are respectively inserted side by side in the refrigerating unit side of the precooler (1) is inserted, the regenerator A first cold side heat exchanger 4A is mounted at the end of (2), and a second cold side heat exchanger 4B is mounted at a start end of the pulsation tube 3, and the first cold side heat exchanger 4A is mounted. Both ends of the connection pipe 5 which communicates each cold side heat exchanger 4A, 4B are respectively equipped with the end surface and the starting end surface of the 2nd cold side heat exchanger 4B. In the drawings, reference numeral 6 denotes an on-side heat exchanger, 7 a phase controller, and 8 a storage container.

그러나, 상기와 같은 종래 맥동관 냉동기에 있어서는, 실질적으로 극저온부가 형성되는 제2 냉측열교환기(4B)의 단면에 반원형 연결관(5)이 장착되므로 결국 제2 냉측열교환기(4B)의 가용면적이 좁아지게 되는 문제점이 있었다.However, in the conventional pulsation tube refrigerator as described above, since the semicircular connector tube 5 is mounted on the cross section of the second cold side heat exchanger 4B in which the cryogenic portion is substantially formed, the available area of the second cold side heat exchanger 4B eventually becomes. There was a problem of this narrowing.

또한, 상기 연결관(5)의 길이가 길어져 사체적이 증가함에 따라 외부로부터 열침투가 용이하여 재생기(2)에서 맥동관(3)으로 작동가스가 이동하는 중에 재가열되면서 냉동효율이 저하되는 문제점도 있었다.In addition, as the length of the connecting pipe (5) is increased and the body volume increases, it is easy to penetrate the heat from the outside to reheat while the working gas is moved from the regenerator (2) to the pulsating pipe (3) also has a problem of lowering the freezing efficiency there was.

본 발명은 상기와 같은 종래 맥동관 냉동기가 가지는 문제점을 감안하여 안출한 것으로, 냉측열교환기의 가용면적을 최대한으로 증가시킬 수 있는 맥동관 냉동기를 제공하려는데 그 목적이 있다.The present invention has been made in view of the problems of the conventional pulsating tube freezer as described above, and an object thereof is to provide a pulsating tube freezer which can increase the available area of the cold side heat exchanger to the maximum.

또한, 작동가스가 재생기에서 맥동관으로 이동하는 중에 재가열되는 것을 최소한으로 줄일 수 있는 맥동관 냉동기를 제공하려는데도 그 목적이 있다.It is also an object of the present invention to provide a pulsating tube freezer which can minimize the reheating of the working gas from the regenerator to the pulsating tube.

The inside of the cold side heat exchanger is provided with a pulsating tube chiller, which is formed to be bent so as to penetrate the inner passage connecting the regenerator and the pulsating tube to the same side.

이하, 본 발명에 의한 맥동관 냉동기를 첨부도면에 도시된 일실시예에 의거하여 상세하게 설명한다.Hereinafter, the pulsating tube freezer according to the present invention will be described in detail based on the embodiment shown in the accompanying drawings.

도 3은 본 발명 맥동관 냉동기의 냉동유니트를 보인 종단면도이다.Figure 3 is a longitudinal sectional view showing a refrigeration unit of the present invention pulse tube refrigerator.

이에 도시된 바와 같이 본 발명에 의한 U타입 맥동관 냉동기는, 압축유니트(P)의 일측에 결합한 예냉기(1)의 냉동유니트쪽 측면에 재생기(2)와 맥동관(3)이 냉측열교환기(10)를 사이에 두고 서로 연통하도록 나란하게 배치되어 결합된다.상기 냉측열교환기(10)는 양측면이 평평한 봉형상으로 형성되되 그 동일 측면에 상기한 재생기(2)와 맥동관(3)이 함께 결합할 수 있도록 내부에는 "ㄷ"자 단면 형상으로 된 내부유로를 형성한다. 또, 냉측열교환기(10)의 타측면은 평평한 상태로 형성된다.상기 내부유로(11)의 맥동관측 출구단에는 열교환기용 망상부재(12)가 삽입되는 것이 바람직하다.또, 상기 맥동관(3)의 타단은 예냉기(1)에 삽입되어 그 예냉기(1)를 측면쪽으로 관통하는 위상제어기(7)와 연결되고, 그 위상제어기(7)는 소정의 내부체적을 갖는 저장용기(8)에 연결된다.도면중 종래와 동일한 부분에 대하여는 동일한 부호를 부여하였다.As shown therein, the U-type pulsating tube refrigerator according to the present invention has a regenerator 2 and a pulsating tube 3 on the side of the freezing unit side of the precooler 1 coupled to one side of the compression unit P. The cold side heat exchanger 10 is formed in the shape of a flat bar on both sides, and the regenerator 2 and the pulsation tube 3 are formed on the same side thereof. The inner flow path is formed in the cross-sectional shape of the letter "c" to be combined together. In addition, the other side surface of the cold side heat exchanger 10 is formed in a flat state. It is preferable that the heat exchanger mesh member 12 is inserted into the pulsation tube outlet end of the internal passage 11. The other end of 3) is connected to a phase controller 7 which is inserted into the precooler 1 and penetrates the precooler 1 to the side, and the phase controller 7 has a storage container 8 having a predetermined internal volume. In the drawings, the same reference numerals are given to the same parts as in the prior art.

도면중 미설명 부호인 6은 온측열교환기이다.In the drawings, reference numeral 6 denotes an on-side heat exchanger.

상기와 같이 구성되는 본 발명에 의한 맥동관 냉동기의 작용효과는 다음과 같다.Effects of the pulsating tube refrigerator according to the present invention configured as described above are as follows.

즉, 상기 냉측열교환기(10)가 '봉'형상으로 형성되되 그 일측면에 재생기(2)와 맥동관(3)이 함께 연통되어 장착되므로, 상기 맥동관(3)의 맞은편인 냉측열교환기(10)의 타측 면에는 아무것도 장착되지 않고 평평한 상태로 유지되어 그 냉측열교환기(10)의 나머지 면은 모두 소자를 붙여 냉각시킬 수 있는 가용면적이 되고, 이를 통해 냉동기의 효용성이 현저하게 향상된다.That is, the cold side heat exchanger 10 is formed in a 'rod' shape, but the regenerator 2 and the pulsation tube 3 are mounted together on one side thereof so that the cold side heat exchanger is opposite to the pulsation tube 3. On the other side of the machine 10, nothing is mounted and it is kept flat, and the remaining side of the cold side heat exchanger 10 becomes an available area for attaching elements to cool, thereby significantly improving the utility of the refrigerator. do.

또한, 상기 재생기(2)에서 맥동관(3)으로 향하는 작동가스가 하나의 블록으로 이루어진 냉측열교환기(10)의 내부유로(11)를 통해 이동하게 되므로 사체적이 줄어 외부로부터의 열침투가 감소되고 이로 인해 냉측열교환기(10)로 유입되는 작동가스의 온도가 상대적으로 저온상태를 유지할 수 있어 냉동기의 냉동효율이 향상된다.In addition, since the working gas directed from the regenerator 2 to the pulsation tube 3 is moved through the internal flow passage 11 of the cold side heat exchanger 10 formed of one block, the body volume is reduced, thereby reducing the heat penetration from the outside. As a result, the temperature of the working gas introduced into the cold side heat exchanger 10 can be maintained at a relatively low temperature, thereby improving the freezing efficiency of the refrigerator.

본 발명에 의한 맥동관 냉동기는, 작동가스를 펌핑하는 압축유니트에 재생기와 냉측열교환기와 맥동관과 온측열교환기와 위상제어수단 그리고 저장용기가 연이어 설치되고, 그 중 재생기와 맥동관은 서로 나란하게 배치되며, 상기 냉측열교환기의 내부에는 재생기와 맥동관을 직접 연결하는 내부유로를 동일측면으로 관통하도록 절곡 형성하여서 구성됨으로써, 상기 냉측열교환기의 가용면적이 확대되어 냉동기의 효용성이 향상되는 것은 물론 상기 연결관의 길이가 짧아져 사체적이 감소함에 따라 냉동기의 효율이 향상된다.The pulsating tube refrigerator according to the present invention is provided with a regenerator, a cold side heat exchanger, a pulsating tube, a warm side heat exchanger, a phase control means, and a storage container connected to a compression unit for pumping working gas, among which the regenerator and the pulsating tube are arranged side by side. The internal side of the cold side heat exchanger is formed by bending the inner flow path directly connecting the regenerator and the pulsating tube to the same side, thereby increasing the available area of the cold side heat exchanger, thereby improving the utility of the refrigerator. As the length of the connecting pipe is shortened and the dead volume is reduced, the efficiency of the refrigerator is improved.
