Description

熱交換器および冷却装置Heat exchanger and cooling device
　本発明は、熱交換器および冷却装置に関し、特に、冷媒を流すための流路としての複数の穴を有する多穴管を備える熱交換器および冷却装置に関する。 The present invention relates to a heat exchanger and a cooling device, and more particularly to a heat exchanger and a cooling device including a multi-hole tube having a plurality of holes as a flow path for flowing a refrigerant.
　従来、冷媒を流すための流路としての複数の穴を有する多穴管を備える熱交換器が知られている。このような熱交換器は、たとえば、特開２０１２－３２０８９号公報に開示されている。 Conventionally, a heat exchanger having a multi-hole tube having a plurality of holes as a flow path for flowing a refrigerant is known. Such a heat exchanger is disclosed in, for example, Japanese Patent Application Laid-Open No. 2012-32089.
　上記特開２０１２－３２０８９号公報には、扁平多穴管と、扁平多穴管の複数の流路を接続するジョイントとを備える熱交換器が開示されている。上記の熱交換器では、ジョイントは、ろう付けにより、扁平多穴管に接続されている。 The above-mentioned Japanese Patent Application Laid-Open No. 2012-32089 discloses a heat exchanger including a flat multi-hole tube and a joint for connecting a plurality of flow paths of the flat multi-hole tube. In the heat exchanger described above, the joints are connected to the flat multi-hole tube by brazing.
特開２０１２－３２０８９号公報Japanese Unexamined Patent Publication No. 2012-32089
　しかしながら、上記特許文献１記載の熱交換器では、ジョイントは、ろう付けにより、扁平多穴管に接続されるため、容易に変形しない材料により形成されると考えられる。そのため、熱交換を行う対象物の立体形状および周囲のスペース（取り付けスペース）に合わせて、ジョイントを容易に変形させることができないので、熱交換を行う対象物の周囲のスペースが狭い場合では、熱交換器を容易に取り付けることができないという問題点がある。 However, in the heat exchanger described in Patent Document 1, since the joint is connected to the flat multi-hole tube by brazing, it is considered that the joint is formed of a material that does not easily deform. Therefore, the joint cannot be easily deformed according to the three-dimensional shape of the object to be heat-exchanged and the surrounding space (mounting space). Therefore, when the space around the object to be heat-exchanged is narrow, heat is generated. There is a problem that the exchanger cannot be easily installed.
　この発明は、上記のような課題を解決するためになされたものであり、この発明の１つの目的は、熱交換を行う対象物の周囲のスペースが狭い場合でも容易に取り付けることが可能な熱交換器および冷却装置を提供することである。 The present invention has been made to solve the above problems, and one object of the present invention is heat that can be easily attached even when the space around the object to be heat exchanged is narrow. It is to provide a exchanger and a cooling device.
　この発明の第１の局面における熱交換器は、冷媒を流すための流路としての複数の穴を有する第１多穴管と、第１多穴管の一方の端部側において、第１多穴管と接続された可撓性を有するヘッダとしての第１可撓性部材と、第１多穴管の他方の端部側において、第１多穴管と接続された可撓性を有するヘッダとしての第２可撓性部材と、を備え、第１可撓性部材は、第１多穴管の一方の端部側において、第１多穴管の複数の流路を接続するように構成され、第２可撓性部材は、第１多穴管の他方の端部側において、第１多穴管の複数の流路を接続するように構成されている。 The heat exchanger in the first aspect of the present invention has a first multi-hole pipe having a plurality of holes as a flow path for flowing a refrigerant and a first multi-hole pipe on one end side of the first multi-hole pipe. A first flexible member as a flexible header connected to a hole tube, and a flexible header connected to the first multi-hole tube on the other end side of the first multi-hole tube. The first flexible member is configured to connect a plurality of flow paths of the first multi-hole pipe on one end side of the first multi-hole pipe. The second flexible member is configured to connect a plurality of flow paths of the first multi-hole pipe on the other end side of the first multi-hole pipe.
　この発明の第２の局面における冷却装置は、冷媒を流すための流路としての複数の穴を有する第１多穴管と、第１多穴管の一方の端部側において、第１多穴管と接続された可撓性を有するヘッダとしての第１可撓性部材と、第１多穴管の他方の端部側において、第１多穴管と接続された可撓性を有するヘッダとしての第２可撓性部材と、を備え、第１可撓性部材は、第１多穴管の一方の端部側において、第１多穴管の複数の流路を接続するように構成され、第２可撓性部材は、第１多穴管の他方の端部側において、第１多穴管の複数の流路を接続するように構成されている。 The cooling device in the second aspect of the present invention has a first multi-hole pipe having a plurality of holes as a flow path for flowing a refrigerant, and a first multi-hole pipe on one end side of the first multi-hole pipe. A first flexible member as a flexible header connected to a pipe, and a flexible header connected to a first multi-hole pipe on the other end side of the first multi-hole pipe. The first flexible member is configured to connect a plurality of flow paths of the first multi-hole pipe on one end side of the first multi-hole pipe. The second flexible member is configured to connect a plurality of flow paths of the first multi-hole pipe on the other end side of the first multi-hole pipe.
　本発明によれば、上記のように、第１多穴管の一方の端部側において、第１多穴管と接続された可撓性を有するヘッダとしての第１可撓性部材と、第１多穴管の他方の端部側において、第１多穴管と接続された可撓性を有するヘッダとしての第２可撓性部材と、を備える。これにより、第１可撓性部材および第２可撓性部材を、熱交換を行う対象物に沿わせて折り曲げることにより、狭いスペースでも設置することができる。その結果、熱交換を行う対象物（冷却対象物）の周囲のスペースが狭い場合でも容易に取り付けることが可能な熱交換器および冷却装置を提供することができる。 According to the present invention, as described above, on one end side of the first multi-hole tube, a first flexible member as a flexible header connected to the first multi-hole tube, and a first. On the other end side of the one multi-hole tube, a second flexible member as a flexible header connected to the first multi-hole tube is provided. As a result, the first flexible member and the second flexible member can be installed even in a narrow space by bending along the object to be exchanged with heat. As a result, it is possible to provide a heat exchanger and a cooling device that can be easily attached even when the space around the object to be heat exchanged (cooling object) is narrow.

　以下、本発明を具体化した実施形態を図面に基づいて説明する。 Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.
　［第１実施形態］
　まず、図１を参照して、第１実施形態による冷却装置１００の構成について説明する。 [First Embodiment]
First, the configuration of the cooling device 100 according to the first embodiment will be described with reference to FIG.
　（冷却装置の構成）
　第１実施形態による冷却装置１００は、複数の蒸発器１０、ポンプ２０、凝縮器３０、貯留部４０および制御部５０を備えている。また、冷却装置１００は、複数の流量制御弁２１および調整弁２２を備える。なお、蒸発器１０は、請求の範囲の「熱交換器」の一例である。また、ポンプ２０は、請求の範囲の「送液部」の一例であり、凝縮器３０は、請求の範囲の「凝縮部」の一例である。 (Cooling device configuration)
The cooling device 100 according to the first embodiment includes a plurality of evaporators 10, a pump 20, a condenser 30, a storage unit 40, and a control unit 50. Further, the cooling device 100 includes a plurality of flow rate control valves 21 and a regulating valve 22. The evaporator 10 is an example of a "heat exchanger" in the claims. Further, the pump 20 is an example of the "liquid feeding unit" in the claims, and the condenser 30 is an example of the "condensation unit" in the claims.
　冷却装置１００は、電子機器のような冷却対象物を冷却するように構成されている。つまり、蒸発器１０は、熱源としての冷却対象物（電子機器）と接するとともに、熱伝導により冷却対象物（電子機器）の熱を奪うように構成されている。 The cooling device 100 is configured to cool an object to be cooled such as an electronic device. That is, the evaporator 10 is configured to be in contact with the cooling object (electronic device) as a heat source and to take away the heat of the cooling object (electronic device) by heat conduction.
　また、冷却装置１００は、冷媒を循環させて熱源としての冷却対象物（電子機器）を冷却するように構成されている。冷媒は、たとえば、フロン系の冷媒である。冷媒は、たとえば、Ｒ２４５ｆａ（大気圧における沸点１５．３℃）である。また、冷媒は、Ｒ２４５ｆａ以外の冷媒、たとえば、水などを冷媒として用いてもよい。また、冷媒を循環させるための流路（冷媒流路）は、金属材料により形成されている。冷媒流路は、たとえば、ステンレス材、アルミニウム材、または、銅材により形成されている。冷媒流路は、パイプ状に形成されている。蒸発器１０、ポンプ２０、凝縮器３０および貯留部４０は、それぞれ冷媒流路により接続されている。 Further, the cooling device 100 is configured to circulate the refrigerant to cool the object to be cooled (electronic device) as a heat source. The refrigerant is, for example, a chlorofluorocarbon-based refrigerant. The refrigerant is, for example, R245fa (boiling point 15.3 ° C. at atmospheric pressure). Further, as the refrigerant, a refrigerant other than R245fa, for example, water or the like may be used as the refrigerant. Further, the flow path (refrigerant flow path) for circulating the refrigerant is formed of a metal material. The refrigerant flow path is formed of, for example, a stainless steel material, an aluminum material, or a copper material. The refrigerant flow path is formed in a pipe shape. The evaporator 10, the pump 20, the condenser 30, and the storage unit 40 are each connected by a refrigerant flow path.
　蒸発器１０は、送液された冷媒を蒸発させるように構成されている。具体的には、蒸発器１０内に設けられた流路を冷媒が流れ、蒸発器１０を介して熱源である冷却対象物（電子機器）から冷媒に熱が伝達する。冷媒は、熱が加えられることにより、蒸発器１０内で蒸発（気化）する。蒸発器１０は、冷媒の蒸発潜熱（気化熱）により、熱源である冷却対象物（電子機器）の熱を奪って、冷却対象物（電子機器）を冷却するように構成されている。蒸発器１０出口から出た気液二相の冷媒は、凝縮器３０に送られる。 The evaporator 10 is configured to evaporate the supplied refrigerant. Specifically, the refrigerant flows through the flow path provided in the evaporator 10, and heat is transferred from the object to be cooled (electronic device), which is a heat source, to the refrigerant via the evaporator 10. The refrigerant evaporates (vaporizes) in the evaporator 10 when heat is applied. The evaporator 10 is configured to take heat from a cooling target (electronic device), which is a heat source, by the latent heat of vaporization (heat of vaporization) of the refrigerant to cool the cooling target (electronic device). The gas-liquid two-phase refrigerant discharged from the outlet of the evaporator 10 is sent to the condenser 30.
