Description

本実施形態は、冷蔵庫に関する。 This embodiment relates to a refrigerator.

従来より、放熱用の配管を金属製の外箱の内側に密着させることにより、配管内を流れる冷媒を放熱させて冷却する技術が考えられている。例えば特許文献１には、放熱用の配管を扁平管とし、その扁平管の平坦面を金属製の外箱に密着させることで放熱性能を高める技術が開示されている。 BACKGROUND ART Conventionally, a technique has been considered in which a heat-radiating pipe is brought into close contact with the inner side of a metal outer box to radiate heat of a refrigerant flowing through the pipe to cool it. For example, Patent Document 1 discloses a technique in which a heat dissipation pipe is a flat pipe, and the flat surface of the flat pipe is brought into close contact with a metal outer box to enhance heat dissipation performance.

特開２０１５−５２４００号公報JP, 2005-52400, A

しかし、放熱用の配管を扁平管とした場合、当該配管を曲げた部分において扁平管が潰れてしまい、流路抵抗が増大して流路が詰まり易くなる。そして、流路が詰まってしまうと、冷媒が流れなくなるため放熱性能が低下してしまうという課題がある。 However, when the heat radiation pipe is a flat pipe, the flat pipe is crushed at the bent portion of the pipe, the flow passage resistance increases, and the flow passage is easily clogged. When the flow path is clogged, there is a problem that the heat dissipation performance is deteriorated because the refrigerant does not flow.

本実施形態は、放熱用の配管として扁平管を用いる場合であっても、放熱性能の低下を抑えることができる冷蔵庫を提供する。 The present embodiment provides a refrigerator capable of suppressing a decrease in heat radiation performance even when a flat pipe is used as a heat radiation pipe.

本実施形態に係る冷蔵庫は、外箱と、前記外箱の内側に設けられる放熱用の配管であって、複数の流路を含む扁平管と、を備え、前記扁平管が扁平面に沿って曲げられているとともに、直線部および曲部を有し、前記直線部と当該直線部の一端側の前記曲部について、当該曲部の外側の流路の断面積は、当該直線部の外側の流路の断面積よりも小さく、当該直線部の外側の流路の断面積は、当該直線部の内側の流路の断面積よりも大きく、且つ、当該直線部の一端側の前記曲部の外側の流路の断面積よりも大きい。 The refrigerator according to the present embodiment includes an outer box and a heat dissipation pipe provided inside the outer box, and a flat tube including a plurality of flow paths, and the flat tube extends along a flat surface. While being bent, it has a straight line portion and a curved portion, and with respect to the straight line portion and the curved portion on one end side of the straight line portion, the cross-sectional area of the flow path outside the curved portion is the outside of the straight line portion. It is smaller than the cross-sectional area of the flow passage, the cross-sectional area of the flow passage outside the straight line portion is larger than the cross-sectional area of the flow passage inside the straight line portion, and the curved portion of one end side of the straight line portion. It is larger than the cross-sectional area of the outer flow path .

以下、冷蔵庫に係る一実施形態について図面を参照しながら説明する。図１に例示する冷蔵庫１０は、その外殻を構成する断熱箱体１１の内部に、食品類が貯蔵される貯蔵室１２を備える。また、冷蔵庫１０は、貯蔵室１２を開閉する図示しない扉を備える。貯蔵室１２は、周知の冷蔵室、冷凍室、野菜室などである。冷蔵庫１０には、貯蔵室を冷却するための図示しない冷凍サイクルが備えられている。冷凍サイクルは、圧縮機、凝縮器、キャピラリチューブ、冷却器などを冷媒管により接続した構成である。 An embodiment of a refrigerator will be described below with reference to the drawings. The refrigerator 10 illustrated in FIG. 1 includes a storage chamber 12 in which foods are stored, inside a heat insulating box 11 that forms the outer shell of the refrigerator 10. The refrigerator 10 also includes a door (not shown) that opens and closes the storage chamber 12. The storage room 12 is a known refrigerating room, freezing room, vegetable room, or the like. The refrigerator 10 is provided with a refrigerating cycle (not shown) for cooling the storage compartment. The refrigeration cycle has a configuration in which a compressor, a condenser, a capillary tube, a cooler and the like are connected by a refrigerant pipe.

断熱箱体１１は、金属製の外箱２１と合成樹脂製の内箱２２との間に、断熱材として、真空断熱パネル２３および発泡ウレタン２４を備えている。そして、断熱箱体１１は、外箱２１と真空断熱パネル２３との間に、放熱用の配管として扁平管３１を備えている。扁平管３１は、冷凍サイクルの冷媒管の一部を構成するものであり、凝縮器とキャピラリチューブとの間に設けられている。真空断熱パネル２３の外箱２１側の面は、扁平管３１を収容するための溝を有しない平面状となっている。 The heat insulating box body 11 includes a vacuum heat insulating panel 23 and a urethane foam 24 as heat insulating materials between an outer box 21 made of metal and an inner box 22 made of synthetic resin. The heat insulating box 11 is provided with a flat tube 31 as a heat radiation tube between the outer box 21 and the vacuum heat insulating panel 23. The flat tube 31 constitutes a part of the refrigerant tube of the refrigeration cycle, and is provided between the condenser and the capillary tube. The surface of the vacuum heat insulating panel 23 on the outer box 21 side is a flat surface having no groove for accommodating the flat tube 31.

図２に例示するように、扁平管３１は、その平坦な面状の扁平面に沿って曲げられた構成となっており、直線状に延びる直線部３２、および、直線部３２間に設けられる曲部３３を有する。直線部３２および曲部３３を有する扁平管３１において、その扁平面は、直線部３２および曲部３３を含む連続した平坦な面状となっている。 As illustrated in FIG. 2, the flat tube 31 is configured to be bent along the flat planar flat surface thereof, and is provided between the linear portions 32 that linearly extend and between the linear portions 32. It has a curved portion 33. In the flat tube 31 having the straight portion 32 and the curved portion 33, the flat surface thereof is a continuous flat surface including the straight portion 32 and the curved portion 33.

図３に例示するように、扁平管３１は、冷媒が流れる複数の流路３４を有している。なお、説明の便宜上、図には最も外側の流路３４ａと最も内側の流路３４ｂのみを示している。即ち、扁平管３１は、最も外側の流路３４ａと最も内側の流路３４ｂとの間にさらに流路を備える構成であってもよいし、最も外側の流路３４ａおよび最も内側の流路３４ｂのみを備える構成であってもよい。 As illustrated in FIG. 3, the flat tube 31 has a plurality of flow paths 34 through which the refrigerant flows. For convenience of explanation, only the outermost flow passage 34a and the innermost flow passage 34b are shown in the drawing. That is, the flat tube 31 may be configured to further include a flow path between the outermost flow path 34a and the innermost flow path 34b, or the outermost flow path 34a and the innermost flow path 34b. It may be configured to include only.

曲部３３は、直線部３２の一部を扁平管３１の扁平面に沿って曲げることにより形成されたものである。よって、曲部３３は、直線部３２の外側部分が延ばされることで形成された部分となっている。即ち、図３に例示するように、直線部３２の外側の肉厚Ｄａは、直線部３２の内側の肉厚Ｄｂよりも大きくなっている。また、直線部３２の外側の流路３４ａの断面積Ｓａは、直線部３２の内側の流路３４ｂの断面積Ｓｂよりも大きくなっている。なお、流路の断面積とは、扁平管３１の各部において流路３４が延びる方向、つまり、冷媒が流れる方向に対し直交する方向に沿う断面の面積である。 The curved portion 33 is formed by bending a part of the straight portion 32 along the flat surface of the flat tube 31. Therefore, the curved portion 33 is a portion formed by extending the outer portion of the straight portion 32. That is, as illustrated in FIG. 3, the outer wall thickness Da of the linear portion 32 is larger than the inner wall thickness Db of the linear portion 32. Further, the cross-sectional area Sa of the flow passage 34a outside the straight portion 32 is larger than the cross-sectional area Sb of the flow passage 34b inside the straight portion 32. The cross-sectional area of the flow passage is the area of the cross section along the direction in which the flow passage 34 extends in each part of the flat tube 31, that is, the direction orthogonal to the direction in which the refrigerant flows.

そして、このように構成されている直線部３２の一部を曲げて曲部３３を形成すると、曲げられた部分の外側が延ばされるような状態となるため、外側の肉厚は薄くなり、また、外側の流路３４ａの断面積は小さくなる。このように形成される曲部３３において、当該曲部３３の外側の流路３４ａの断面積Ｓｃは、直線部３２の外側の流路３４ａの断面積Ｓａよりも小さくなる。また、曲部３３の内側の流路３４ｂの断面積Ｓｄは、曲部３３の外側の流路３４ａの断面積Ｓｃ以上の大きさとなる。また、直線部３２の外側の肉厚Ｄａは、曲部３３の外側の肉厚Ｄｃよりも大きくなる。また、直線部３２の外側の流路３４ａの断面積Ｓａは、曲部３３の外側の流路３４ａの断面積Ｓｃよりも大きくなる。 Then, when the curved portion 33 is formed by bending a part of the straight line portion 32 configured as described above, the outside of the bent portion is extended, so that the thickness of the outside becomes thin and The cross-sectional area of the outer flow path 34a becomes smaller. In the curved portion 33 thus formed, the cross-sectional area Sc of the flow passage 34a outside the curved portion 33 is smaller than the cross-sectional area Sa of the flow passage 34a outside the straight portion 32. Further, the cross-sectional area Sd of the flow passage 34b inside the curved portion 33 is larger than the cross-sectional area Sc of the flow passage 34a outside the curved portion 33. The outer wall thickness Da of the straight line portion 32 is larger than the outer wall thickness Dc of the curved portion 33. Further, the cross-sectional area Sa of the flow passage 34a outside the straight portion 32 is larger than the cross-sectional area Sc of the flow passage 34a outside the curved portion 33.

本実施形態に係る冷蔵庫１０によれば、扁平面に沿って曲げられた放熱用の扁平管３１は、複数の流路３４を有している。この構成によれば、仮に１つあるいはいくつかの流路３４が詰まってしまったとしても、他の流路３４により冷媒を流すことができるため、放熱性能の低下を抑えることができる。 According to the refrigerator 10 of the present embodiment, the flat tube 31 for heat dissipation bent along the flat surface has the plurality of flow paths 34. According to this configuration, even if one or some of the flow passages 34 are clogged, the refrigerant can flow through the other flow passages 34, so that it is possible to suppress deterioration in heat dissipation performance.

また、冷蔵庫１０によれば、曲部３３の外側の流路３４ａの断面積Ｓｃは、直線部３２の外側の流路３４ａの断面積Ｓａよりも小さくなっている。即ち、直線部３２の外側の流路３４ａが引き延ばされることにより形成される曲部３３の外側の流路３４ａは、その断面積Ｓｃが直線部３２の断面積Ｓａよりも小さくなるはずである。従って、曲部３３の外側の流路３４ａの断面積Ｓｃと直線部３２の外側の流路３４ａの断面積Ｓａとの大小関係が「Ｓａ＞Ｓｃ」であることを確認することにより、曲部３３が直線部３２を引き延ばすことにより形成されたものであることを特定することができる。 Further, according to the refrigerator 10, the cross-sectional area Sc of the flow passage 34a outside the curved portion 33 is smaller than the cross-sectional area Sa of the flow passage 34a outside the straight portion 32. That is, the cross-sectional area Sc of the flow passage 34a outside the curved portion 33 formed by stretching the flow passage 34a outside the straight portion 32 should be smaller than the cross-sectional area Sa of the straight portion 32. .. Therefore, by confirming that the cross-sectional area Sc of the flow passage 34a outside the curved portion 33 and the cross-sectional area Sa of the flow passage 34a outside the linear portion 32 is "Sa>Sc", the curved portion It can be specified that 33 is formed by extending the straight line portion 32.

また、冷蔵庫１０によれば、直線部３２の外側の肉厚Ｄａは、直線部３２の内側の肉厚Ｄｂよりも大きくなっている。即ち、曲部３３を形成するために引き延ばされる直線部３２の外側部分の肉厚Ｄａを大きくしておくことにより、形成される曲部３３の外側の肉厚Ｄｃを十分に確保することができ、曲部３３の強度を確保することができる。 Further, according to the refrigerator 10, the outer wall thickness Da of the linear portion 32 is larger than the inner wall thickness Db of the linear portion 32. That is, by increasing the wall thickness Da of the outer portion of the straight line portion 32 that is stretched to form the curved portion 33, it is possible to sufficiently secure the outer wall thickness Dc of the formed curved portion 33. Therefore, the strength of the curved portion 33 can be secured.

なお、直線部３２が引き延ばされることにより形成される曲部３３の外側の肉厚Ｄｃは、引き延ばされる前の直線部３２の外側の肉厚Ｄａよりも薄くなる。換言すれば、直線部３２の外側の肉厚Ｄａは、曲部３３の外側の肉厚Ｄｃよりも大きくなる。即ち、直線部３２の外側部分が引き延ばされることにより形成される曲部３３の外側部分は、その肉厚Ｄｃが直線部３２の肉厚Ｄａよりも薄くなるはずである。従って、曲部３３の外側部分の肉厚Ｄｃと直線部３２の外側部分の肉厚Ｄａとの大小関係が「Ｄａ＞Ｄｃ」であることを確認することにより、曲部３３が直線部３２を引き延ばすことにより形成されたものであることを特定することができる。 The outer wall thickness Dc of the curved portion 33 formed by extending the straight portion 32 is thinner than the outer wall thickness Da of the straight portion 32 before being stretched. In other words, the outer wall thickness Da of the straight portion 32 is larger than the outer wall thickness Dc of the curved portion 33. That is, the thickness Dc of the outer portion of the curved portion 33 formed by extending the outer portion of the straight portion 32 should be smaller than the thickness Da of the straight portion 32. Therefore, by confirming that the magnitude relationship between the wall thickness Dc of the outer portion of the curved portion 33 and the wall thickness Da of the outer portion of the straight portion 32 is “Da>Dc”, the curved portion 33 can It can be specified that it was formed by stretching.

また、冷蔵庫１０によれば、直線部３２の外側の流路３４ａの断面積Ｓａを、直線部３２の内側の流路３４ｂの断面積Ｓｂよりも大きくしておくことで、直線部３２が引き延ばされて形成された曲部３３において、外側の流路３４ａの方が内側の流路３４ｂよりもより大きく縮小するため、外側の流路３４ａの断面積Ｓｃと内側の流路３４ｂの断面積Ｓｄとをほぼ等しくすることができる。 Further, according to the refrigerator 10, by setting the cross-sectional area Sa of the flow passage 34a outside the linear portion 32 to be larger than the cross-sectional area Sb of the flow passage 34b inside the linear portion 32, the straight portion 32 is drawn. In the bent portion 33 formed by being extended, the outer flow passage 34a is reduced more largely than the inner flow passage 34b, so that the cross-sectional area Sc of the outer flow passage 34a and the inner flow passage 34b are cut off. The area Sd can be made substantially equal.

また、冷蔵庫１０によれば、直線部３２の外側の流路３４ａの断面積Ｓａは、当該直線部３２の外側部分が引き延ばされて形成される曲部３３の外側の流路３４ａの断面積Ｓｃよりも大きくなるはずである。従って、直線部３２の外側の流路３４ａの断面積Ｓａと曲部３３の外側の流路３４ａの断面積Ｓｃとの大小関係が「Ｓａ＞Ｓｃ」であることを確認することにより、曲部３３が直線部３２を引き延ばすことにより形成されたものであることを特定することができる。 Further, according to the refrigerator 10, the cross-sectional area Sa of the flow passage 34a outside the linear portion 32 is determined by cutting the flow passage 34a outside the curved portion 33 formed by extending the outer portion of the linear portion 32. It should be larger than the area Sc. Therefore, by confirming that the size relationship between the cross-sectional area Sa of the flow passage 34a outside the straight portion 32 and the cross-sectional area Sc of the flow passage 34a outside the curved portion 33 is "Sa>Sc", It can be specified that 33 is formed by extending the straight line portion 32.

また、冷蔵庫１０によれば、曲部３３の内側の流路３４ｂの断面積Ｓｄは、曲部３３の外側の流路３４ａの断面積Ｓｃ以上の大きさとなっている。即ち、上述した通り、本実施形態に係る冷蔵庫１０によれば、曲部３３の外側の流路３４ａの断面積Ｓｃと内側の流路３４の断面積Ｓｄとをほぼ等しくすることができるが、この場合、外側の流路３４ａは、引き延ばされて形成されることから、内側の流路３４ｂに比べより大きく縮小する傾向がある。そのため、曲部３３の外側の流路３４ａの方が内側の流路３４ｂよりも若干小さくなる傾向がある。 Further, according to the refrigerator 10, the cross-sectional area Sd of the flow passage 34b inside the curved portion 33 is larger than the cross-sectional area Sc of the flow passage 34a outside the curved portion 33. That is, as described above, according to the refrigerator 10 of the present embodiment, the cross-sectional area Sc of the flow passage 34a outside the curved portion 33 and the cross-sectional area Sd of the flow passage 34 inside can be made substantially equal. In this case, since the outer flow path 34a is formed by being stretched, the outer flow path 34a tends to be more greatly reduced than the inner flow path 34b. Therefore, the flow passage 34a outside the curved portion 33 tends to be slightly smaller than the flow passage 34b inside.

また、冷蔵庫１０によれば、真空断熱パネル２３の外箱２１側の面は、扁平管３１を収容するための溝を有しない平面状となっている。扁平管３１を収容するための溝を真空断熱パネル２３に設けた場合、その溝の形成に伴い真空断熱パネル２３の断熱性能が低下する。本実施形態によれば、真空断熱パネル２３に溝を形成することなく、扁平管３１を外箱２１と真空断熱パネル２３との間に挟み込むように配置する構成であるため、真空断熱パネル２３の断熱性能が低下してしまうおそれがない。 Further, according to the refrigerator 10, the surface of the vacuum heat insulating panel 23 on the outer box 21 side is a flat surface having no groove for accommodating the flat tube 31. When a groove for accommodating the flat tube 31 is provided in the vacuum heat insulation panel 23, the heat insulation performance of the vacuum heat insulation panel 23 is deteriorated as the groove is formed. According to the present embodiment, the flat tube 31 is arranged so as to be sandwiched between the outer box 21 and the vacuum heat insulating panel 23 without forming a groove in the vacuum heat insulating panel 23. There is no fear that the heat insulation performance will deteriorate.

本実施形態に係る冷蔵庫によれば、外箱と、前記外箱の内側に設けられる放熱用の配管であって、複数の流路を含む扁平管と、を備える。そして、前記扁平管は、扁平面に沿って曲げられている。この構成によれば、放熱用の配管として扁平管を用いる場合であっても、曲げた部分において複数の配管が全て詰まってしまう可能性は極めて少ないため、少なくとも何れかの流路により冷媒を流すことができ、放熱性能の低下を抑えることができる。 The refrigerator according to the present embodiment includes an outer box and a heat-dissipating pipe provided inside the outer box and having a flat tube including a plurality of flow paths. The flat tube is bent along the flat surface. According to this configuration, even if a flat pipe is used as the heat radiation pipe, the possibility that all of the plurality of pipes will be clogged at the bent portion is extremely small, and therefore the refrigerant is flowed through at least one of the flow paths. Therefore, it is possible to suppress deterioration of heat dissipation performance.

なお、本実施形態は、上述した実施形態に限定されるものではなく、例えば次のように拡張または変形することができる。例えば、扁平管に備える流路の数や断面形状は、適宜変更して実施することができる。 The present embodiment is not limited to the above-described embodiment, and can be expanded or modified as follows, for example. For example, the number of channels and the cross-sectional shape of the flat tube can be changed as appropriate.

以上、本発明の一実施形態を説明したが、本実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。この新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。本実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. The present embodiment and its modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the scope equivalent thereto.
