Abstract

This invention concerns a Stirling Cycle type cooling device (1) where a heat exchanger (7) is used to ensure the heat transfer between the cold surface (5) of the Stirling cooler (2) and the internal medium to be cooled on the one hand, and the hot surface (6) of the Stirling cooler (2) and the outer medium where the thermal energy is rejected on the other hand, without using any additional fan systems.

Description

本発明は、スターリングサイクル型冷却器と共に作動する冷却装置に関する。   The present invention relates to a cooling device that works with a Stirling cycle cooler.

幾つかの冷却用途において、圧縮機を使用するシステムのものに近い冷却効率係数を有する無ピストンスターリング冷却器が好まれる。スターリング冷却器は、外部媒質からの熱エネルギの吸収を保証する低温面と、リニアエンジンにより往復運動されるピストンにより発生された圧縮力により熱エネルギの排出を保証する高温面とを特徴とする。低温面は、熱サイフォンシステムによって冷却器内部の熱を吸収する一方、高温面は、別の熱サイフォンシステムにより、吸収されたエネルギを冷却器から外に排出する。熱交換器は、スターリング冷却器の低温側及び高温側の小さい表面積に設置される一方、これらの熱交換器が必要とされる熱量を伝達するため、実際には大きい面積が必要とされ、このため、熱交換器に対する理想的な表面積とこの目的のために利用可能な実際の面積との間に不一致が生ずることがある。この不一致を是正するため、すなわち熱交換器の機能を向上させるため、冷却器内部のエネルギは、ファン強制による熱流によって外部に伝達され、その結果、エネルギ消費量及びコストが増大する。   In some cooling applications, a pistonless Stirling cooler with a cooling efficiency factor close to that of a system using a compressor is preferred. The Stirling cooler is characterized by a low temperature surface that guarantees the absorption of heat energy from the external medium and a high temperature surface that guarantees the discharge of heat energy by the compression force generated by the piston reciprocated by the linear engine. The cold surface absorbs heat inside the cooler by the thermosyphon system, while the hot surface discharges the absorbed energy out of the cooler by another thermosyphon system. While heat exchangers are installed on the low surface area and the high surface area of the Stirling cooler, these heat exchangers actually transfer the amount of heat required, so a large area is actually required, Thus, there may be a discrepancy between the ideal surface area for the heat exchanger and the actual area available for this purpose. In order to correct this discrepancy, i.e. to improve the function of the heat exchanger, the energy inside the cooler is transferred to the outside by a fan forced heat flow, resulting in increased energy consumption and cost.

米国特許出願第２００２―０１３４８８号明細書において、凝縮器及び蒸発器端部を有する熱サイフォン装置を備えるスターリング冷却器により作動される冷却システムが記載されており、これらの端部間の接続は、１つの大径の管と、１つの小径の管とにより実現される。   In U.S. Patent Application No. 2002-013488, a cooling system is described which is operated by a Stirling cooler comprising a thermosiphon device having condenser and evaporator ends, the connection between these ends being This is realized by one large-diameter tube and one small-diameter tube.

日本国特許出願第２００３―０７５０００号明細書において、スターリング冷却器に取り付けられて、その低温面を通じて熱エネルギを吸収し、流動する冷却流体をその本体の中空領域内に封じ込める熱交換器及び冷却ファンが記載されている。   In Japanese Patent Application No. 2003-075000, a heat exchanger and cooling fan attached to a Stirling cooler, absorbs heat energy through its cold surface, and encloses flowing cooling fluid in a hollow region of its body Is described.

本発明の目的は、追加的なファン装置を使用せずに、スターリング冷却器の低温面と、装置の内部媒質と、スターリング冷却器の高温面と、エネルギが追い出される外部媒質との間にて熱交換が行われる冷却装置を実現することである。   It is an object of the present invention to avoid the use of an additional fan device between the cold surface of the Stirling cooler, the internal medium of the device, the hot surface of the Stirling cooler, and the external medium from which energy is expelled. It is to realize a cooling device in which heat exchange is performed.

本発明の目的を実現するため具体化された冷却装置は、添付図面に示されている。
冷凍機、深冷凍機、飲料容器等のような冷却装置（１）は、本体（２０）と、冷却作用を実現するスターリング冷却器（２）と、自由に流動するか又はポンプにより作動される冷却流体を循環させて冷却装置（１）の内部媒質内に存在する熱エネルギを吸収する蒸発器（３）と、自由に流動するか又は又はポンプにより作動される冷却流体を保持し、熱を冷却装置（１）の外部に排出する凝縮器（４）とを収容している。 A cooling device embodied to realize the objects of the invention is shown in the accompanying drawings.
A cooling device (1), such as a refrigerator, deep refrigerator, beverage container, etc., is free flowing or actuated by a pump with a main body (20), a Stirling cooler (2) that realizes a cooling action. An evaporator (3) that circulates the cooling fluid and absorbs the thermal energy present in the internal medium of the cooling device (1) and holds the cooling fluid that is free-flowing or pumped, The condenser (4) discharged to the outside of the cooling device (1) is accommodated.

スターリング冷却器（２）は、本体（２０）内に配置されることが好ましく、低温側にて保持されたガスが膨張する間、外部からの熱エネルギの吸収を保証する低温面（５）と、本体（２０）の外部に配置されることが好ましく、その内部に保持されたガスを圧縮する間、熱エネルギの排出を保証する高温面（６）とを備えている。   The Stirling cooler (2) is preferably disposed in the body (20), and a low temperature surface (5) that ensures absorption of heat energy from the outside while the gas held on the low temperature side expands; It is preferably arranged outside the body (20) and has a high temperature surface (6) that ensures the discharge of thermal energy while compressing the gas held inside.

スターリング冷却器（２）を使用する冷却装置（１）は、凝縮効果を有していて低温面（５）にしっかりと取り付けられ、蒸発器（３）内にて発生された熱を、冷却流体を凝縮することにより低温面（５）に伝達する、熱交換器（７）及び（又は）蒸発効果を有していて高温面（６）にしっかりと取り付けられ、内部を冷却流体が流れ且つ、凝縮器（４）から来る冷却流体を蒸発させることにより、高温面（６）にて発生された熱を伝達する、熱交換器（７）を備えている。   The cooling device (1) using the Stirling cooler (2) has a condensing effect and is firmly attached to the cold surface (5), and the heat generated in the evaporator (3) is transferred to the cooling fluid. A heat exchanger (7) and / or an evaporation effect, which is transmitted to the cold surface (5) by condensing and is firmly attached to the hot surface (6), the cooling fluid flows inside, and A heat exchanger (7) is provided that transfers the heat generated at the hot surface (6) by evaporating the cooling fluid coming from the condenser (4).

熱交換器（７）は、冷却流体が流れる１つ又はより多数の流れ管（１１）と、流れ管（１１）により形成された部分を蒸発器（３）又は凝縮器（４）から来る管と連結し得る設計とされた１つ又は幾つかの接続要素（１２）とを保持している。熱交換器（７）は、低温面（５）又は高温面（６）を完全に封入するように組み合わされた流れ管（１１）を重ね合わせることにより、形成されることが好ましい。接続要素（１２）は、単一の入口及び単一の出口を備えるか、又は、１つ以上の蒸発器が使用されるならば、３ウェイ又は４ウェイの配置とすることができる。   The heat exchanger (7) consists of one or more flow tubes (11) through which the cooling fluid flows and the part formed by the flow tubes (11) coming from the evaporator (3) or the condenser (4) And one or several connecting elements (12) designed to be able to be coupled. The heat exchanger (7) is preferably formed by superimposing the flow tubes (11) combined so as to completely enclose the cold surface (5) or the hot surface (6). The connecting element (12) can have a single inlet and a single outlet, or it can be a three-way or four-way arrangement if more than one evaporator is used.

蒸発器（３）及び(又は)凝縮器（４）から来る管が接続要素（１２）によって熱交換器（７）に接続される場合、冷却流体が流れる部分は、変更されて、好ましくは、増大させ、流れが拡がるのを保証し、これにより冷却流体が幾つかの流路にて再分配され、これにより全体的な流れ面積、及び実際の熱交換が生ずる接触面を増大させる。   If the tubes coming from the evaporator (3) and / or the condenser (4) are connected to the heat exchanger (7) by means of a connecting element (12), the part through which the cooling fluid flows is changed, preferably Increase and ensure that the flow spreads, so that the cooling fluid is redistributed in several channels, thereby increasing the overall flow area and the contact surface where the actual heat exchange takes place.

流れ管（１１）は、スターリング冷却器（２）の低温面（５）又は高温面（６）と接触し得るよう半円形の形状とされた接触面（８）と、曲げることにより平坦化されて接触面（８）の両側部に配置され、他の流れ管（１１）との接続を保証する２つの接続面（９）と、全体的な熱交換面を増大させる設計とされた１つ又はより多くの流路（１０）とを備えている。   The flow tube (11) is flattened by bending with a semicircular shaped contact surface (8) that can contact the cold surface (5) or hot surface (6) of the Stirling cooler (2). One of the two contact surfaces (9) arranged on both sides of the contact surface (8) to ensure connection with the other flow pipe (11) and one designed to increase the overall heat exchange surface Or more flow paths (10).

好ましい適用例において、流れ管（１１）は、例えば、１ｍｍ×１ｍｍの間隔の狭い流路（１０）を形成し得るようにアルミニウム系材料にて押出し成形されることが好ましい。焼鈍アルミニウムが、所望の断面に対し１０ないし２０の流路（１０）を生成させる鋳型に対して押し付けられ、鋳型から出るとき、流れ管（１１）に変形される。次に、熱交換器（７）の一部として使用される流れ管（１１）は、所望の長さに切断することができる。更に、使用される材料の柔軟性のため、流れ管は、容易に形状をとることができる。   In a preferred application, the flow tube (11) is preferably extruded from an aluminum-based material so as to form a narrow channel (10) having a spacing of, for example, 1 mm × 1 mm. Annealed aluminum is pressed against a mold that creates 10 to 20 channels (10) for the desired cross-section and is transformed into a flow tube (11) when exiting the mold. The flow tube (11) used as part of the heat exchanger (7) can then be cut to the desired length. Furthermore, due to the flexibility of the materials used, the flow tube can be easily shaped.

スターリング冷却器の（２）の低温面（５）に配置され、凝縮器として作用する、熱交換器（７）を通じて凝縮により液体状態を取得する冷却流体は、次に、蒸発器（３）に導かれる。冷却装置（１）の蒸発器（３）の巡回路を通って流れる冷却流体は、キャビン内の熱負荷を吸収し且つ、蒸気に変換され、もう１回、熱交換器（７）に到達し、これによりサイクルを完了させる。   The cooling fluid, which is placed on the cold surface (5) of the Stirling cooler (2) and acts as a condenser and acquires a liquid state by condensation through the heat exchanger (7), then passes to the evaporator (3). Led. The cooling fluid flowing through the circuit of the evaporator (3) of the cooling device (1) absorbs the heat load in the cabin and is converted into steam and reaches the heat exchanger (7) once more. This completes the cycle.

スターリング冷却器（２）の高温面（６）に配置されて、蒸発器として作用する熱交換器（７）を通る間、蒸発し且つ気体状態に変化する冷却流体は、次に、凝縮器（４）に導かれる。凝縮器（４）の巡回路を通って流れる冷却流体は、該流体が運んだ熱を外部媒質に伝達し、再度、熱交換器（７）に到達し、これによりサイクルを完了する。   Cooling fluid that evaporates and changes to a gaseous state while passing through the heat exchanger (7), which is arranged on the hot surface (6) of the Stirling cooler (2) and acts as an evaporator, is then condensed ( 4). The cooling fluid flowing through the circuit of the condenser (4) transfers the heat carried by the fluid to the external medium and reaches the heat exchanger (7) again, thereby completing the cycle.

凝縮器（４）内にて凝縮する冷却流体は、凝縮器（４）から出るとき、小径の管内に蓄積し且つ、柱状の液体を形成し、柱状の液体により発生された差圧のため、システム内にて循環が開始される。システム内の流量は、最初に増大し、その後、管圧の降下程度は柱状の液体により発生された静圧差に等しくなり、流れに起因する摩擦損失が柱状の液体の圧力エネルギに等しくなるとき、流量出力は一定となる。蒸発器（３）内にて循環する冷却液体は、冷却装置（１）の内部から熱エネルギを吸収することにより、蒸発し始める。蒸発器（３）の垂直方向の循環路にて、冷却流体は気体状の状態にあると考えられる。低温側の入口に配置された熱交換器（７）に到達する冷却流体は流路（１０）に分配される。単一の流路（１０）の流れ面積は蒸発器（３）の流れ面積よりも遥かに小さいが、組み合わさった流路（１０）を通る全流量出力は、蒸発器（３）からの流量に等しい。流量出力を流路（１０）に分配すると、流れの速度は低下し、この速度低下は、流れ面積（断面）の減少に関係した速度の増大よりも有効であるため、圧力損失は著しく増大せず、循環は続く。   The cooling fluid that condenses in the condenser (4) accumulates in the small diameter tube as it exits the condenser (4) and forms a columnar liquid, due to the differential pressure generated by the columnar liquid, Circulation starts in the system. When the flow rate in the system first increases, then the extent of the drop in tube pressure is equal to the static pressure difference generated by the columnar liquid, and when the friction loss due to flow is equal to the pressure energy of the columnar liquid, The flow rate output is constant. The cooling liquid circulating in the evaporator (3) starts to evaporate by absorbing heat energy from the inside of the cooling device (1). It is considered that the cooling fluid is in a gaseous state in the vertical circulation path of the evaporator (3). The cooling fluid reaching the heat exchanger (7) arranged at the low temperature side inlet is distributed to the flow path (10). The flow area of the single flow path (10) is much smaller than the flow area of the evaporator (3), but the total flow output through the combined flow path (10) is the flow rate from the evaporator (3). be equivalent to. Distributing the flow output to the flow path (10) reduces the flow velocity, which is more effective than the velocity increase associated with the reduced flow area (cross-section), so the pressure loss increases significantly. The cycle continues.

本発明の別の適用例において、冷却装置（１）は、スターリング冷却器（２）の高温面（６）に取り付けられた熱交換器（７）とは別に、スターリング冷却器（２）の低温面（５）に取り付けられたフィン付き熱交換器（１３）と、送風ファン（１４）と、空気の流れを導く空気路（１５）とを備えている。この適用例において、冷却装置（１）の内部（キャビン）内に存在する熱エネルギは、ファン（１４）及びフィン付き熱交換器（１３）による強制的な流れにより伝達される一方、高温面（６）における熱エネルギは、最初に、凝縮器（４）に、次に、熱交換器（７）を通じて外部媒質に伝達される。   In another application of the invention, the cooling device (1) has a low temperature of the Stirling cooler (2) separately from the heat exchanger (7) attached to the hot surface (6) of the Stirling cooler (2). A finned heat exchanger (13) attached to the surface (5), a blower fan (14), and an air passage (15) for guiding the flow of air are provided. In this application, the thermal energy present in the interior of the cooling device (1) (cabin) is transferred by forced flow by the fan (14) and the finned heat exchanger (13), while the hot surface ( The thermal energy in 6) is first transferred to the condenser (4) and then to the external medium through the heat exchanger (7).

本発明の別の適用例において、熱交換器は、スターリング冷却器（２）の低温面（５）に取り付けられ、フィン付き熱交換器（１３）は、スターリング冷却器（２）の高温面（６）に取り付けられる。この適用例において、高温面（６）にて発生された熱は、ファン（１４）及びフィン付き熱交換器（１３）による強制的な流れにより伝達される一方、低温面（５）は蒸発器（７）により熱エネルギを吸収する。   In another application of the invention, the heat exchanger is attached to the cold surface (5) of the Stirling cooler (2) and the finned heat exchanger (13) is connected to the hot surface of the Stirling cooler (2) ( 6). In this application, the heat generated at the hot surface (6) is transferred by forced flow through the fan (14) and the finned heat exchanger (13), while the cold surface (5) is an evaporator. Absorb heat energy by (7).

本発明の更に別の適用例において、低温面（５）に配置された熱交換器（７）又は高温面（６）に配置された熱交換器（７）或いはその双方の熱交換器は、絶縁材料（１６）により被覆されている。高温面（６）に配置された熱交換器（７）が本体（２０）の外部にあるならば、該熱交換器は、絶縁材料（１６）により被覆されないことが好ましい一方、熱交換器が本体（２０）の内部に配置されるならば、熱交換器は絶縁材料（１６）により被覆されることが好ましい。このため、熱交換器（７）の外面は、周囲の媒体から隔離されており、これにより流れ管（１１）内を循環する冷却流体によりスターリング冷却器（２）の低温面（５）と高温面（６）との間の伝熱過程の効率が増大する。   In yet another application of the invention, the heat exchanger (7) located on the cold face (5) and / or the heat exchanger (7) located on the hot face (6), It is covered with an insulating material (16). If the heat exchanger (7) located on the hot surface (6) is outside the body (20), it is preferred that the heat exchanger is not covered by the insulating material (16), while the heat exchanger If placed inside the body (20), the heat exchanger is preferably covered with an insulating material (16). For this reason, the outer surface of the heat exchanger (7) is isolated from the surrounding medium, so that the cooling fluid circulating in the flow pipe (11) and the cold surface (5) of the Stirling cooler (2) are hot. The efficiency of the heat transfer process with the surface (6) is increased.

熱交換器（７）内に収容された流れ管（１１）の構造体とスターリング冷却器（２）の低温面及び高温面（５、６）との間の直接的な接触の結果、より効率的な冷却作用が実現される。冷却装置（１）内の空気と蒸発器（３）内を循環する冷却流体との間又は外部空気と凝縮器（４）内を循環する冷却流体との間の伝熱は低い温度差にて実現されるため、エネルギ消費量は減少する一方、冷却装置（１）の冷却性能は向上する。   More efficiency as a result of direct contact between the structure of the flow tube (11) housed in the heat exchanger (7) and the cold and hot surfaces (5, 6) of the Stirling cooler (2). Cooling action is realized. Heat transfer between the air in the cooling device (1) and the cooling fluid circulating in the evaporator (3) or between the external air and the cooling fluid circulating in the condenser (4) has a low temperature difference. Since the energy consumption is reduced, the cooling performance of the cooling device (1) is improved.
