Description

쿨러의 재생기{Regenarator of cooler}Regenerator of cooler

본 발명은 쿨러에 관한 것으로서, 보다 상세하게는 축열재의 재질적인 특성상 제작이 용이하고, 성능이 향상된 쿨러의 재생기에 관한 것이다.The present invention relates to a cooler, and more particularly, to a regenerator of a cooler that is easy to manufacture due to the material properties of the heat storage material and has improved performance.

쿨러는 헬륨 등의 냉매를 이용하여 극저온 냉각작용을 수행하는 것으로, 도 1에 나타난 것과 같이 밀폐용기(10)와, 상기 밀폐용기(10)내에 구비되며, 냉매가 충진되는 실린더(20)와, 상기 실린더(20) 내에 장착된 피스톤(22)과, 실린더(20)의 일측에 구비된 디스플레이서 실린더(30)와, 상기 디스플레이서 실린더(30)내에 이동 가능하게 장착되어 피스톤(22)과 연동되어 냉매가스를 압축, 팽창시키는 디스플레이서(32)와, 냉매가스로부터 열에너지를 흡수하여 축적/방출하는 재생기(40)와, 상기 피스톤(22)의 작동을 위한 리니어 모터(50)를 포함하여 이루어진다.The cooler performs cryogenic cooling by using a coolant such as helium. As shown in FIG. 1, the cooler is provided in the sealed container 10, the sealed container 10, and a cylinder 20 filled with a coolant. The piston 22 mounted in the cylinder 20, the displacer cylinder 30 provided on one side of the cylinder 20, and the displaceable cylinder 30 are movably mounted in the displacer cylinder 30 to interlock with the piston 22. And a displacer 32 for compressing and expanding the refrigerant gas, a regenerator 40 for absorbing and accumulating and discharging thermal energy from the refrigerant gas, and a linear motor 50 for operating the piston 22. .

한편, 재생기는 그 구성위치에 따라 외장형과 내장형으로 이루어지는데, 외장형 재생기는 밀폐용기 외부의 냉매 흡입/배출관을 통해 연결된 하우징과, 상기 하우징내에 구비된 축열재로 이루어져 있다.(미도시)On the other hand, the regenerator is made of an external type and a built-in type according to the configuration position, the external regenerator is composed of a housing connected through the refrigerant intake / discharge pipe outside the sealed container, and the heat storage material provided in the housing (not shown).

그리고, 내장형 재생기는 디스플레이서(32)와 공동구성되는 것으로서, 도 2에 나타난 것과 같이 원통형의 하우징(42)과, 상기 하우징(42)내에 삽입 장착된 축열재(44)와, 하우징(42)의 선단에 부착된 엔드캡(46)으로 이루어져 있다.The built-in regenerator is co-configured with the displacer 32, and has a cylindrical housing 42, a heat storage member 44 inserted into the housing 42, and a housing 42, as shown in FIG. It consists of an end cap 46 attached to the tip of the.

상기 축열재(44)는 냉매가스와 접하여 열교환함으로써 냉매가스로부터 에너지를 받아서 축적하였다가 되돌려 주는 역할을 하기 때문에 열교환 면적 및 비열이크고, 열전도 계수가 작으며 냉매가스가 통과할 수 있는 다공성의 폴리에스테르 섬유재질로 만들어지며, 소정 직경 및 길이의 원주블록형태로 우선 성형된 다음, 다수개의 원주블록이 연속배치되는 이른바 다중겹 구조로 장착되어 있다.The heat storage member 44 receives and accumulates energy from the refrigerant gas by exchanging heat in contact with the refrigerant gas, thereby accumulating and returning the heat. The heat exchange area 44 has a large heat exchange area, a specific heat, a small thermal conductivity coefficient, and a porous poly gas through which the refrigerant gas can pass. Made of ester fiber material, it is first molded into a columnar block of a predetermined diameter and length, and then mounted in a so-called multi-ply structure in which a plurality of columnar blocks are continuously arranged.

여기서, 상기 축열재(44)를 다중겹 구조로 장착하는 이유는, 축열재(44)를 단일체로 형성하여 사용할 경우, 재질적인 특성상(다공성 섬유재), 하우징(42)에 삽입장착하는 과정에서 먼저 삽입되는 선단부위가 압축됨으로써 전체적으로 균일한 통기성을 유지하기 어렵기 때문이다.Here, the reason for mounting the heat storage material 44 in a multi-ply structure, when the heat storage material 44 is formed in a single body, due to the material properties (porous fiber material), in the process of inserting and mounting in the housing 42 This is because it is difficult to maintain uniform breathability as a result of the compression of the tip inserted first.

그리고, 상기 원주블록형태의 축열재(44)를 제작하는 방법은 길이가 긴 원주형태로 성형한 다음, 절단하여 짧은 길이의 블록으로 만드는 이른바 절단식이 아니라, 짧은 길이의 축열재 블록을 개별적으로 성형하는 개별 성형식을 사용하게 되는데, 이는 축열재(44)의 재질적인 특성상 절단면이 거칠어지기 때문에 절단식으로 제작된 축열재 블록을 다수개 적층하면 각 블록간 경계면이 고르게 접촉되지 않아 통기성이 저하되기 때문이다.In addition, the method of manufacturing the columnar block-type heat storage member 44 is not a so-called cutting type that is formed into a long columnar shape, and then cut into a short length block, separately forming a short length heat storage material block separately. In this case, since the cutting surface becomes rough due to the material properties of the heat storage material 44, when a plurality of heat storage material blocks manufactured by the cutting method are laminated, the interface between each blocks is not evenly contacted so that the air permeability is reduced. Because.

그러므로, 상술한 바와 같은 종래기술에 의하면 재생기(44)를 구성하기 위해 다수개의 축열재 블록을 성형하는 번거로운 작업을 필요로 함과 더불어 성형된 블록을 하우징(42)에 삽입적층하는 과정에서도 압착되지 않도록 많은 주의를 기울여야 함으로써 쿨러의 생산성이 저하되는 한 원인이 된다는 문제점이 발생한다.Therefore, according to the prior art as described above, a cumbersome operation of forming a plurality of heat storage material blocks to construct a regenerator 44 is required, and also the process of inserting the molded blocks into the housing 42 is not compressed. Since a great deal of care must be taken to avoid causing the problem that the cooler's productivity is reduced.

또한, 종래기술에 의하면 재질적인 특성상 축열재(44)가 대략 60℃ 이상의 고온에서는 경화되어 재생작용을 원활히 수행할 수 없기 때문에 결과적으로 쿨러의 사용조건 제약이 심해진다는 문제점 또한 발생한다.In addition, according to the related art, the heat storage material 44 is hardened at a high temperature of about 60 ° C. or higher due to its material characteristics, and thus, a problem arises that the use condition of the cooler becomes severe as a result.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로서, 메탈 화이바 재질의 축열재가 적용됨으로써 제작이 용이하고, 성능이 향상되는 쿨러의 재생기 제공을 목적으로 한다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and is intended to provide a cooler regenerator that is easy to manufacture and improves performance by applying a heat storage material made of metal fiber material.

상기 목적을 달성하기 위하여 제공되는 쿨러의 재생기는 원통형의 하우징과, 상기 하우징내에 삽입 장착된 축열재와, 하우징의 선단에 부착된 엔드캡을 포함하며, 상기 축열재가 메탈화이버 재질의 단일블록 형태인 것을 특징으로 하여 이루어진다.A cooler regenerator provided to achieve the above object includes a cylindrical housing, a heat storage material inserted into and mounted in the housing, and an end cap attached to a tip of the housing, wherein the heat storage material is in the form of a single block made of metal fiber material. It is characterized by that.

이하, 본 발명의 실시예를 첨부된 도 3을 참조로 하여 상세하게 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 3.

본 발명의 실시예에 따른 쿨러의 재생기는 도면에 나타난 것과 같이 원통형의 하우징(42)과, 상기 하우징(42)내에 삽입 장착된 축열재(45)와, 하우징(42)의 선단에 부착된 엔드캡(44)을 포함하며, 상기 축열재(45)가 메탈화이버 재질인 것을 특징으로 하여 이루어진다.The regenerator of the cooler according to the embodiment of the present invention, as shown in the figure, the cylindrical housing 42, the heat storage material 45 inserted into the housing 42, the end attached to the tip of the housing 42 It includes a cap 44, characterized in that the heat storage material 45 is a metal fiber material.

여기서, 상기 축열재(45)는 메탈화이버 소재의 원단을 금형에 삽입 압착하여 소성가공하는 방식으로 만들어지는데, 메탈화이버는 축열용량이 크고, 열전달 계수가 매우 작은 재질로서, 성형된 후에는 형태가 달라지지 않는다.Here, the heat storage material 45 is made by inserting and compressing the fabric of the metal fiber material into the mold and plastic processing, the metal fiber is a material having a large heat storage capacity, a very small heat transfer coefficient, after being shaped It doesn't change.

따라서, 본 실시예에 의하면 축열재(45)를 하우징(42)에 삽입 장착하는 과정에서 선단이 압착되어 부분적으로 통기성이 달라지는 현상이 발생하지 않기 때문에 축열재(4)를 단일 블록형태로 만들게 장착하게 된다.Therefore, according to the present embodiment, since the tip is compressed in the process of inserting and installing the heat storage material 45 into the housing 42, the phenomenon of partially breathing does not occur, so that the heat storage material 4 is mounted in a single block form. Done.

또한, 본 실시예에 의하면 쿨러의 작동 시에서 냉매가 축열재(45)를 통과하는 과정에서 많은 양의 열량이 축적/방출되므로 쿨러의 성능이 향상되고, 1000℃ 이상의 고온에서도 물성변화가 없는 메탈 화이버의 특성상 쿨러의 사용 가능 온도범위가 확대된다.In addition, according to the present embodiment, since a large amount of heat is accumulated / released during the refrigerant passing through the heat storage material 45 during the operation of the cooler, the performance of the cooler is improved, and the metal does not have any change in physical properties even at a high temperature of 1000 ° C. or higher. Due to the nature of the fiber, the usable temperature range of the cooler is expanded.

이상에서 설명한 바와 같이 본 발명에 따른 쿨러의 재생기는 메탈 화이버 재질로 이루어지는 축열재의 특성상, 제작이 용이하고, 넓은 온도범위에서 사용 가능하기 때문에, 쿨러의 생산성 및 성능 향상에 도움이 된다.As described above, the regenerator of the cooler according to the present invention is easy to manufacture due to the characteristics of the heat storage material made of a metal fiber material and can be used in a wide temperature range, thereby helping to improve the productivity and performance of the cooler.
