図１を参照すれば、本発明の実施例によるスターリング冷凍機用整流ユニット１０が適用される前記スターリング冷凍機１００は、回転シャフト１０３を通じて作動する。前記回転シャフト１０３は、車両のエンジン（図示せず）からプーリ１０１により駆動力の伝達を受けて回転する。前記スターリング冷凍機１００は、ハウジング１０９の内部に充填された作動流体をピストン１０７の往復運動によって圧縮する圧縮部１１０と、前記圧縮部１１０で圧縮された作動流体をピストン１０７の往復運動によって膨張させる膨張部１２０と、前記圧縮部１１０と前記膨張部１２０を流体的に連通させる再生部１３０とを含んで構成される。 Referring to FIG. 1, the Stirling refrigerator 100 to which the rectifying unit 10 for a Stirling refrigerator according to an embodiment of the present invention is applied operates through a rotating shaft 103. The rotating shaft 103 is rotated by receiving a driving force transmitted from a vehicle engine (not shown) by a pulley 101. The Stirling refrigerator 100 compresses the working fluid filled in the housing 109 by the reciprocating motion of the piston 107 and expands the working fluid compressed by the compressing portion 110 by the reciprocating motion of the piston 107. The expansion unit 120 includes a compression unit 110 and a regeneration unit 130 that fluidly communicates the expansion unit 120.
このようなスターリング冷凍機１００は、作動流体の等温圧縮、等積過程、及び等温膨張の反復を通じて圧縮部１１０で発熱して作動流体の温度が上昇し、温度が上昇した作動流体を連結配管１４０によって連結された再生部１３０で再生させた後、前記膨張部１２０で吸熱を通じて作動流体の温度を超低温状態に下げるようになる。 Such a Stirling refrigerator 100 generates heat in the compression unit 110 through the repetition of isothermal compression, isovolumetric process, and isothermal expansion of the working fluid, and the temperature of the working fluid rises. After the regeneration by the regenerative unit 130 connected by the above, the expansion unit 120 reduces the temperature of the working fluid to an ultra-low temperature through heat absorption.
ここで、前記膨張部１２０で温度が低くなった作動流体は、車両に具備された内部の熱交換機を循環する他の作動流体との熱交換が行われ、熱交換を通じて冷却された他の作動流体が、車両の室内に流入する外気を冷却させることにより、車両の冷房が行われる。 Here, the working fluid whose temperature has been lowered in the expansion part 120 is subjected to heat exchange with other working fluid circulating in an internal heat exchanger provided in the vehicle, and is cooled through the heat exchange. The vehicle cools the vehicle by cooling the outside air flowing into the vehicle interior.
前記圧縮部１１０で作動流体が圧縮されれば、前記膨張部１２０で膨張が行われるように、前記圧縮部１１０と膨張部１２０を貫いて設けられた前記回転シャフト１０３上に前記ピストン１０７が装着される。前記ピストン１０７は、互いに設定された位相を有し、圧縮部１１０と膨張部１２０にそれぞれ備わる一対の傾斜板１０５によって前記回転シャフト１０３上に装着される。 When the working fluid is compressed by the compression unit 110, the piston 107 is mounted on the rotary shaft 103 provided through the compression unit 110 and the expansion unit 120 so that the expansion is performed by the expansion unit 120. Is done. The piston 107 has a mutually set phase and is mounted on the rotating shaft 103 by a pair of inclined plates 105 provided in the compression unit 110 and the expansion unit 120, respectively.
そして、前記圧縮部１１０と膨張部１２０は、ピストン１０７が往復移動しながら作動流体を圧縮または膨張させるための圧縮室１１１と膨脹室１２１がそれぞれ設けられる。 The compression unit 110 and the expansion unit 120 are respectively provided with a compression chamber 111 and an expansion chamber 121 for compressing or expanding the working fluid while the piston 107 reciprocates.
また、前記圧縮部１１０と膨張部１２０には、前記ハウジング１０９にそれぞれ設けられる熱交換部１５０をさらに含んで構成される。 The compression unit 110 and the expansion unit 120 further include heat exchange units 150 provided in the housing 109, respectively.
このような構成を有するスターリング冷凍機１００において、本発明の実施例によるスターリング冷凍機用整流ユニット１０は、圧縮部１１０と膨張部１２０に適用されるピストン１０７の往復移動によって等温圧縮または等温膨張した作動流体の流れを円滑にすることにより、作動流体の流動時に圧力平衡をなすようにして、スターリング冷凍機１００の全体的な効率を向上させることができるように形成されている。 In the Stirling refrigerator 100 having such a configuration, the rectifying unit 10 for the Stirling refrigerator according to the embodiment of the present invention is isothermally compressed or isothermally expanded by the reciprocating movement of the piston 107 applied to the compression unit 110 and the expansion unit 120. By making the flow of the working fluid smooth, the overall efficiency of the Stirling refrigerator 100 can be improved by achieving a pressure balance when the working fluid flows.
そのために、本発明の実施例によるスターリング冷凍機用整流ユニット１０は、図２乃至図４に示したように、整流部材１１と固定プレート１３を含んで構成される。
まず、前記整流部材１１は、前記熱交換部１５０の両端部にそれぞれ配置され、圧縮部１１０または膨張部１２０から排出されて前記熱交換部１５０を通過する作動流体を整流するようになる。
For this purpose, the rectifying unit 10 for a Stirling refrigerator according to the embodiment of the present invention includes a rectifying member 11 and a fixed plate 13 as shown in FIGS.
First, the rectifying members 11 are respectively disposed at both ends of the heat exchange unit 150, and rectify the working fluid discharged from the compression unit 110 or the expansion unit 120 and passing through the heat exchange unit 150.
ここで、前記整流部材１１は、前記圧縮部１１０または膨張部１２０を循環する作動流体が圧縮部１１０または膨張部１２０から排出されるとき、作動流体の流動圧力が均一に分布するように、細いワイヤーが不規則的に固まって形成されてもよい。
そして、前記固定プレート１３は、前記各整流部材１１を前記熱交換部１５０の両端にそれぞれ固定させるようになる。
Here, the rectifying member 11 is thin so that when the working fluid circulating through the compression unit 110 or the expansion unit 120 is discharged from the compression unit 110 or the expansion unit 120, the flow pressure of the working fluid is uniformly distributed. The wire may be formed by irregularly solidifying.
The fixing plate 13 fixes the rectifying members 11 to both ends of the heat exchange unit 150.
前記固定プレート１３の一面には、前記熱交換部１５０の両端に配置された前記整流部材１１が挿入される挿入溝１５が形成され、前記挿入溝１５に対応して作動流体が流動するように複数個の貫通孔１７が形成されている。前記熱交換部１５０は、前記貫通孔１７を通じて前記圧縮部１１０または膨張部１２０と連通してもよい。 Insertion grooves 15 into which the rectifying members 11 disposed at both ends of the heat exchange unit 150 are inserted are formed on one surface of the fixed plate 13 so that the working fluid flows corresponding to the insertion grooves 15. A plurality of through holes 17 are formed. The heat exchange unit 150 may communicate with the compression unit 110 or the expansion unit 120 through the through hole 17.
そのために、前記固定プレート１３は、貫通孔１７を通じて前記熱交換部１５０に整流部材１１を通過した作動流体を流入させ、整流部材１１を通過しながら流動圧力が均一に分布された作動流体を円滑に流動させるようになる。 For this purpose, the fixing plate 13 allows the working fluid that has passed through the rectifying member 11 to flow into the heat exchange unit 150 through the through-hole 17, and smoothly flows the working fluid in which the flow pressure is uniformly distributed while passing through the rectifying member 11. To become fluid.
このような固定プレート１３の外周面と前記ハウジング１０９の内周面の間には、シーリング１９が介されてもよい。
また、前記熱交換部１５０の前記固定プレート１３と接触する一面と前記固定プレート１３の間には、シーリング１９が介されてもよい。
A sealing 19 may be interposed between the outer peripheral surface of the fixed plate 13 and the inner peripheral surface of the housing 109.
Further, a sealing 19 may be interposed between the fixed plate 13 and the one surface of the heat exchanging unit 150 that contacts the fixed plate 13.
前記シーリング１９は、前記固定プレート１３の外周面とハウジング１０９の内周面の間と、前記固定プレート１３と熱交換部１５０の一面の間から作動流体が漏れ出ることを防止する機能をするようになる。 The sealing 19 functions to prevent the working fluid from leaking between the outer peripheral surface of the fixed plate 13 and the inner peripheral surface of the housing 109 and between the fixed plate 13 and one surface of the heat exchange unit 150. become.
前記固定プレート１３は、前記ハウジング１０９の内部に形成されたリング溝２１に装着されるスナップリング２３を通じて前記熱交換部１５０の両端部に装着され、前記ハウジング１０９の内部で固定されてもよい。 The fixing plate 13 may be attached to both ends of the heat exchanging part 150 through a snap ring 23 attached to a ring groove 21 formed in the housing 109 and fixed inside the housing 109.
本実施例において、前記スナップリング２３は、前記整流部材１１と固定プレート１３を熱交換部１５０の両端部にそれぞれ固定させる機能と共に、前記熱交換部１５０を前記圧縮部１１０または膨張部１２０で固定させる機能も行う。 In this embodiment, the snap ring 23 has a function of fixing the rectifying member 11 and the fixing plate 13 to both ends of the heat exchanging unit 150 and fixing the heat exchanging unit 150 with the compressing unit 110 or the expanding unit 120. The function to make is also performed.
一方、本実施例において、前記ハウジング１０９の一面は、前記整流部材１１を通過した作動流体の排出時、排出圧力を均一にするように、作動流体が流入または排出される流動孔２５を中心に前記熱交換部１５０に向かって傾いた傾斜面２７に形成されてもよい。
ここで、前記傾斜面２７は、前記流動孔２５を中心に前記流動孔２５から前記整流部材１１側に向かって次第にその直径が広くなるように傾いて形成されてもよい。
On the other hand, in this embodiment, one surface of the housing 109 is centered on the flow hole 25 through which the working fluid flows in or out so as to make the discharge pressure uniform when the working fluid that has passed through the rectifying member 11 is discharged. It may be formed on the inclined surface 27 inclined toward the heat exchange unit 150.
Here, the inclined surface 27 may be formed to be inclined so that the diameter gradually increases from the flow hole 25 toward the rectifying member 11 with the flow hole 25 as a center.
そのために、前記熱交換部１５０を通過した作動流体は、前記整流部材１１を通過しながら圧力が均一に分布されて排出され、前記流動孔２５を通じて排出するときには、前記傾斜面２７に沿って前記流動孔２５から均一な圧力が発生するように誘導される。 Therefore, the working fluid that has passed through the heat exchanging unit 150 is discharged with the pressure uniformly distributed while passing through the rectifying member 11, and is discharged along the inclined surface 27 when discharged through the flow hole 25. It is induced so that a uniform pressure is generated from the flow hole 25.
つまり、整流部材１１を通過した作動流体が直径が狭くなる連結配管１４０を通過するとき、前記傾斜面２７は、作動流体が均一な圧力で連結配管１４０を通過するように誘導する。したがって、前記傾斜面２７は、前記整流部材１１と共に作動流体の圧力分布を均一にして、流動の流れを円滑にする機能を行うようになる。 That is, when the working fluid that has passed through the rectifying member 11 passes through the connecting pipe 140 whose diameter is narrowed, the inclined surface 27 guides the working fluid to pass through the connecting pipe 140 with a uniform pressure. Therefore, the inclined surface 27 performs a function of making the pressure distribution of the working fluid uniform with the rectifying member 11 and smoothing the flow of the flow.
したがって、本発明の実施例によるスターリング冷凍機用整流ユニット１０を適用すれば、スターリング冷凍機１００において圧縮部１１０と膨張部１２０に備わるピストン１０７の往復移動により、等温圧縮または等温膨張した作動流体が熱交換部１５０を通過しながら、圧力が均一に分布するようになり、これによって圧縮部１１０、膨張部１２０、及び再生部１３０の間で流動する作動流体の流れを円滑にすることができる。 Accordingly, when the rectifying unit 10 for a Stirling refrigerator according to the embodiment of the present invention is applied, the working fluid that has been isothermally compressed or isothermally expanded by the reciprocating movement of the piston 107 provided in the compression unit 110 and the expansion unit 120 in the Stirling refrigerator 100. While passing through the heat exchanging unit 150, the pressure is uniformly distributed, whereby the flow of the working fluid flowing between the compression unit 110, the expansion unit 120, and the regeneration unit 130 can be made smooth.
また、作動流体の円滑な流れは、直径の小さい連結配管１４０を通過する作動流体の流動経路上で圧力平衡をなすようになるので、圧縮部１１０と膨張部１２０で作動流体の圧縮率と膨脹率をさらに向上させることができ、スターリング冷凍機１００の全体的な効率を向上させることが可能である。 In addition, since the smooth flow of the working fluid is in pressure balance on the flow path of the working fluid passing through the connecting pipe 140 having a small diameter, the compressibility and expansion of the working fluid are compressed by the compression unit 110 and the expansion unit 120. The rate can be further improved, and the overall efficiency of the Stirling refrigerator 100 can be improved.
以上、本発明は、たとえ限定された実施例と図面によって説明されたが、本発明はこれらによって限定されず、本発明が属する技術分野における通常の知識を有する者によって、本発明の技術思想と特許請求の範囲の均等範囲内で多様な修正及び変形が可能であることはもちろんである。 Although the present invention has been described with reference to the limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention can be determined by those having ordinary knowledge in the technical field to which the present invention belongs.
