Description

熱交換器Heat exchanger
　本発明は熱交換器に関し、とくに、専用の固定用部材を用いることなく抗菌部材を低コ ストで設置可能であり、抗菌部材の設置により熱交換効率を低下させることなく、しかも、設計の自由度を高く維持可能な熱交換器に関する。 The present invention relates to a heat exchanger, and in particular, an antibacterial member can be installed at a low cost without using a dedicated fixing member, the heat exchange efficiency is not lowered by the installation of the antibacterial member, and the design is free. The present invention relates to a heat exchanger capable of maintaining a high degree.
　熱交換器、とくに、空調装置において空気通路内に設けられる蒸発器等の熱交換器にお いては、従来から細菌やかびの発生を防止する方法が各種提案されている。例えば、特許文献１には、抗菌防かび剤を含浸させた抗菌部材を熱交換器の上端部に設け、抗菌部材の 表面に発生した凝縮水により抗菌成分が溶解され、抗菌成分を含む凝縮水が熱交換器表面を流下することにより、抗菌機能を発揮させるようにした熱交換器が開示されている。

Japanese Patent Laid-Open No. 2004-361031
　しかしながら、特許文献１に開示された熱交換器においては、抗菌部材の設置部位は熱交換器の上端部のみに限定されており、この抗菌部材の設置により熱交換器全体の設計の自由度が低下するという懸念がある。また、特許文献１に開示されている実施態様においては、抗菌部材を固定するための専用の係止爪や熱伝導板が設けられており、部品コストおよび組立コストの増加を招くおそれがあるとともに、熱交換器の小型化、軽量化が難しくなるという問題があった。 However, in the heat exchanger disclosed in Patent Document 1, the installation site of the antibacterial member is limited only to the upper end portion of the heat exchanger, and the installation of the antibacterial member allows a degree of freedom in designing the entire heat exchanger. There is concern that it will decline. In addition, in the embodiment disclosed in Patent Document 1, a dedicated locking claw and a heat conduction plate for fixing the antibacterial member are provided, which may cause an increase in parts cost and assembly cost. There was a problem that it was difficult to reduce the size and weight of the heat exchanger.
　そこで本発明の課題は、専用の固定用部材を用いることなく抗菌部材を低コストで設置可能であり、抗菌部材の設置による熱交換効率の低下がたとえ生じたとしても最小限に抑制され、設計の自由度を抗菌部材を設置しない従来技術とほぼ同水準に高く維持可能な熱交換器を提供することにある。 Therefore, the problem of the present invention is that the antibacterial member can be installed at low cost without using a dedicated fixing member, and even if a decrease in heat exchange efficiency due to the installation of the antibacterial member occurs, it is minimized and designed. Is to provide a heat exchanger that can maintain a high degree of freedom at a level substantially the same as that of the prior art without an antibacterial member.
　上記課題を解決するために、本発明に係る熱交換器は、少なくとも面状に配列され熱交換媒体が流通する複数のチューブを含む放熱部材を備えた熱交換器であって、抗菌成分を保持する吸水性シート基材を該放熱部材に対し部分的に着設し、前記吸水性シート基材に吸水された水分を介して前記抗菌成分を前記放熱部材の表面に沿わせて拡散可能に構成したことを特徴とするものからなる。 In order to solve the above problems, a heat exchanger according to the present invention is a heat exchanger having a heat radiating member including at least a plurality of tubes arranged in a planar shape and through which a heat exchange medium flows, and holds an antibacterial component A water-absorbing sheet base material that is partially attached to the heat-dissipating member, and the antibacterial component can be diffused along the surface of the heat-dissipating member through the water absorbed by the water-absorbing sheet base material It consists of what is characterized by.
　このような熱交換器によれば、抗菌成分を保持する部材として、水分の吸収および放出が容易に可能な吸水性シート基材が用いられているので、一時的に吸収された水分に抗菌成分が溶出された後、速やかにその水分がシート外部へ放出されることが可能となり、抗菌成分が速やかに放熱部材の表面に沿わせて広範囲にわたって拡散される。また、水分の放出が容易であることから、吸水性シート基材内に吸水された水分に抗菌成分が溶出された後その抗菌成分含有水分が順次放出されていくので、吸水性シート基材は大きな水分保持機能を有する面積の広い部材に構成される必要はなく、熱交換性能に影響を及ぼさない部位に部分的に設置されればよい。したがって、熱交換器自体の熱交換効率の低下が防止されるか、たとえあってもその熱交換効率の低下が最小限に抑えられる。 According to such a heat exchanger, since the water-absorbent sheet base material capable of easily absorbing and releasing moisture is used as a member for holding the antimicrobial component, the antimicrobial component is temporarily absorbed into the moisture. After the elution, the moisture can be quickly released to the outside of the sheet, and the antibacterial component is quickly diffused over a wide area along the surface of the heat dissipation member. In addition, since the release of moisture is easy, the antibacterial component-containing moisture is sequentially released after the antibacterial component is eluted in the water absorbed in the water absorbent sheet substrate. It does not need to be configured as a large-area member having a large moisture retention function, and may be partially installed at a site that does not affect the heat exchange performance. Therefore, a decrease in the heat exchange efficiency of the heat exchanger itself is prevented, or even if the decrease in the heat exchange efficiency is minimized.
　本発明に係る吸水性シート基材は、水分の吸収および放出が容易に可能であるため、抗菌成分の拡散をさまざまな形態で実現可能である。例えば、放熱部材の表面に膜状の水層が形成され、水層の一部が吸水性シート基材と接している場合、抗菌成分が水層へと溶出されて拡散し、抗菌成分の効果が水層全体に対して発揮される。また、放熱部材の表面に水の流路が形成されている場合、吸水性シート基材を上流に配置することにより、抗菌成分が溶出された水が放熱部材の表面に形成された流路を流れることとなり、放熱部材の表面における抗菌成分の拡散が達成される。なお、上記の流路を通過する水流は、連続的な水流であってもよいし、離散的な水流（例えば、放熱部材の表面を断続的に滴下する水滴等）であってもよい。 Since the water-absorbent sheet base material according to the present invention can easily absorb and release moisture, the antibacterial component can be diffused in various forms. For example, when a film-like water layer is formed on the surface of the heat radiating member and a part of the water layer is in contact with the water absorbent sheet base material, the antibacterial component is eluted and diffused into the water layer, and the effect of the antibacterial component Is exerted on the entire water layer. In addition, when a water flow path is formed on the surface of the heat radiating member, by arranging the water absorbent sheet base material upstream, a flow path in which water from which the antibacterial component is eluted is formed on the surface of the heat radiating member is formed. The antibacterial component is diffused on the surface of the heat dissipation member. The water flow that passes through the flow path may be a continuous water flow or a discrete water flow (for example, a water droplet that drops intermittently on the surface of the heat dissipation member).
　本発明に係る吸水性シート基材は、上述の如く、抗菌成分の拡散をさまざまな形態で実現可能であるため、熱交換器の利用形態に応じた設置方法を選択することが可能である。また、シート形態であることから、設置スペースが小さくて済むとともに、設置部位に対応した大きさや形状への加工が容易であり、熱交換器の設計の自由度を従来の抗菌部材を設置しない場合とほぼ同様の高い水準に維持することが可能となり、吸水性シート基材の設置による製造コストの上昇や熱交換器周辺機器への影響が抑制される。 Since the water-absorbent sheet base material according to the present invention can realize the diffusion of antibacterial components in various forms as described above, it is possible to select an installation method according to the use form of the heat exchanger. In addition, since it is in the form of a sheet, the installation space can be small, and processing into a size and shape corresponding to the installation site is easy, and the degree of freedom in designing the heat exchanger is not installed with conventional antibacterial members As a result, it is possible to maintain the same high level as in the above, and an increase in manufacturing cost due to the installation of the water-absorbent sheet base material and influence on peripheral equipment of the heat exchanger are suppressed.
　本発明に係る吸水性シート基材において、抗菌成分を拡散させるための水分としては、とくに限定されないが、放熱部材表面に結露した凝縮水を利用することができる。凝縮水の流水径路を利用して抗菌成分を拡散させることにより、抗菌成分の拡散のための流路を新たに設ける必要がなくなり、熱交換器の製造コストの上昇が抑制される。 In the water absorbent sheet substrate according to the present invention, the moisture for diffusing the antibacterial component is not particularly limited, but condensed water condensed on the surface of the heat radiating member can be used. By diffusing the antibacterial component using the flow path of the condensed water, it is not necessary to newly provide a channel for the diffusion of the antibacterial component, and an increase in the manufacturing cost of the heat exchanger is suppressed.
　本発明に係る吸水性シート基材は、設置形態についてはとくに限定されない。例えば、吸水性シート基材が放熱部材であるチューブ配列面に対し部分的に着設されている場合、吸水性シート基材は接着もしくは締結によりチューブ配列面上に固定されていてもよいし、チューブ配列面に固定するための固定用部材が用いられていてもよい。しかしながら、設置作業の容易性および部品コスト削減の観点から、吸水性シート基材は、専用の固定用部材を追加することなく、チューブ配列面に対し非接合的に着設されていることが好ましい。このような設置形態としては、例えば、チューブ配列面の端部近傍部位に断熱シール部材が備えられている熱交換器において、断熱シール部材とチューブとの間に吸水性シート基材を介装させる形態等が挙げられる。 The water absorbent sheet base material according to the present invention is not particularly limited with respect to the installation form. For example, when the water absorbent sheet substrate is partially attached to the tube arrangement surface that is a heat dissipation member, the water absorbent sheet substrate may be fixed on the tube arrangement surface by adhesion or fastening, A fixing member for fixing to the tube array surface may be used. However, from the viewpoint of ease of installation work and cost reduction of parts, it is preferable that the water-absorbent sheet base material is attached non-joined to the tube arrangement surface without adding a dedicated fixing member. . As such an installation form, for example, in a heat exchanger in which a heat insulating seal member is provided near the end portion of the tube arrangement surface, a water absorbent sheet base material is interposed between the heat insulating seal member and the tube. The form etc. are mentioned.
　また、本発明に係る放熱部材は、上記複数のチューブのみに限定されず、例えば、チューブ配列方向端部に設けられたエンドプレート、複数のチューブの端部が接続されたヘッダ、各チューブ間に備えられたフィン等が含まれていてもよい。このようなチューブ以外の放熱部材においても、吸水性シート基材は、上述のように、専用の固定用部材を追加することなく放熱部材に対し非接合的に着設されていることが好ましい。このような設置形態としては、例えば、放熱部材としてチューブ配列方向端部にエンドプレートが設けられ、エンドプレートの表面の少なくとも一部に対しシール部材が配置されている熱交換器において、シール部材とエンドプレートとの間に吸水性シート基材を介装させる形態等が挙げられる。 Further, the heat dissipation member according to the present invention is not limited to the plurality of tubes. For example, an end plate provided at an end portion in the tube arrangement direction, a header to which end portions of the plurality of tubes are connected, and between the tubes. A provided fin or the like may be included. In such a heat radiating member other than the tube, it is preferable that the water-absorbent sheet base material is non-bonded to the heat radiating member without adding a dedicated fixing member as described above.

　以下に、本発明の望ましい実施の形態を、図面を参照して説明する。 図１は、本発明の一実施態様に係る熱交換器の外観を示しており、とくに、チューブ配列面の端部近傍部位に断熱シール部材が備えられている熱交換器において、断熱シール部材とチューブとの間に吸水性シート基材が非接合的に介在された構造を示している。なお、図１（Ａ）においては熱交換器の下端部に、図１（Ｂ）においては熱交換器の上端部に、それぞれ吸水性シート基材が備えられている。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the appearance of a heat exchanger according to an embodiment of the present invention. In particular, in a heat exchanger in which a heat insulating seal member is provided in the vicinity of the end of the tube arrangement surface, It shows a structure in which a water-absorbent sheet base material is interposed non-joined between the tube. In FIG. 1A, a water absorbent sheet base material is provided at the lower end portion of the heat exchanger, and in FIG. 1B, at the upper end portion of the heat exchanger.
　図１において、熱交換器１には、面状に配列され熱交換媒体が流通する複数のチューブ２と、複数のチューブの端部が接続される２本のヘッダ３とが備えられており、ヘッダ３の一方には、熱交換媒体の導入路４および導出路５が設けられている。チューブ２配列面の端部近傍部位およびヘッダ３の外周面上には断熱シール部材６が備えられており、断熱シール部材６とチューブ２との間には吸水性シート基材７が非接合的に介在されている。 In FIG. 1, the heat exchanger 1 includes a plurality of tubes 2 that are arranged in a plane and through which a heat exchange medium flows, and two headers 3 to which ends of the plurality of tubes are connected, One of the headers 3 is provided with a heat exchange medium introduction path 4 and a lead-out path 5. A heat insulating seal member 6 is provided on the vicinity of the end portion of the tube 2 arrangement surface and the outer peripheral surface of the header 3, and the water absorbent sheet base material 7 is non-joint between the heat insulating seal member 6 and the tube 2. Is intervened.
　図２は、本発明の一実施態様に係る熱交換器の外観を示しており、とくに、チューブ配列面の端部近傍部位に断熱シール部材が備えられ、チューブ２配列方向端部にエンドプレート１１が設けられ、エンドプレート１１に対しシール部材１２が配置された熱交換器への適用例を示している。図２において、熱交換器１の下部に備えられた断熱シール部材６ａとチューブ２下端部との間には吸水性シート部材７ａが、熱交換器１の上部に備えられた断熱シール部材６ｂとチューブ２上端部との間には吸水性シート部材７ｂが、シール部材１２とエンドプレート１１との間には吸水性シート部材７ｃが、それぞれ非接合的に介在されている。その他の構成は図１（Ａ）に示した実施態様と同様であるので、図１（Ａ）と同一の符号を付すことにより説明を省略する。図２に示すように、吸水性シート基材７は、複数の放熱部材に対する抗菌機能の発揮を可能とすべく、複数の放熱部材のそれぞれに対して部分的に着設されていてもよい。上述の如く、吸水性シート基材７は設置部位に対応した大きさや形状への加工が容易であり、しかも省スペースであるため、熱交換器１の設計の自由度を高い水準に維持しつつ吸水性シート基材７を複数箇所へ設置することが可能であり、吸水性シート基材７の設置による製造コストの上昇や熱交換器１周辺機器への影響は最小限に抑制される。 FIG. 2 shows the appearance of the heat exchanger according to one embodiment of the present invention. In particular, a heat insulating seal member is provided in the vicinity of the end of the tube arrangement surface, and the end plate 11 is provided at the end of the tube 2 arrangement direction. Is provided, and an example of application to a heat exchanger in which a seal member 12 is disposed with respect to an end plate 11 is shown. In FIG. 2, a water absorbent sheet member 7 a is provided between the heat insulating seal member 6 a provided at the lower portion of the heat exchanger 1 and the lower end portion of the tube 2, and the heat insulating seal member 6 b provided at the upper portion of the heat exchanger 1. A water absorbent sheet member 7b is interposed between the upper ends of the tubes 2, and a water absorbent sheet member 7c is interposed between the seal member 12 and the end plate 11 in a non-joint manner. Since other structures are the same as those of the embodiment shown in FIG. 1A, the same reference numerals as those in FIG. As shown in FIG. 2, the water absorbent sheet base material 7 may be partially attached to each of the plurality of heat radiating members so that the antibacterial function can be exerted on the plurality of heat radiating members. As described above, the water-absorbent sheet base material 7 can be easily processed into a size and shape corresponding to the installation site, and is space-saving, so that the design flexibility of the heat exchanger 1 is maintained at a high level. It is possible to install the water absorbent sheet base material 7 at a plurality of locations, and the increase in manufacturing cost and the influence on the peripheral equipment of the heat exchanger 1 due to the installation of the water absorbent sheet base material 7 are suppressed to the minimum.
　図３は、図１（Ａ）に示した熱交換器のチューブ下端部近傍部位における概略縦断面を示しており、とくに、冷凍回路内において蒸発器として設けられた熱交換器の動作を示している。図３の熱交換器１において、チューブ２の下端部近傍には断熱シール部材６が備えられており、チューブ２および断熱シール部材６の間には吸水性シート基材７が介在されている。蒸発器としての熱交換器１が稼動すると、チューブ２内を流通する冷媒（熱交換媒体）の蒸発熱によってチューブ２が冷却され、チューブ２を通過する空気との間で熱交換（空気冷却）が行われるとともに、チューブ２の表面に凝縮水８が結露することがある。凝縮水８は冷却されており容易に蒸発しないため、結露する量が増加するとチューブ２の表面に凝縮水８からなる膜状の水層９が形成される。水層９が発達してその面積が広がり、水層９の下端部が吸水性シート基材７へ接触すると、吸水性シート基材７に保持されていた抗菌成分１０が水層９へ溶出し、チューブ２の表面へ拡散される。抗菌成分１０が不揮発性であった場合、熱交換器１が停止して凝縮水８および水層９が蒸発すると、拡散された抗菌成分１０はチューブ２の表面へ残存し、熱交換器１が再度稼動して凝縮水８からなる水層９が形成されたときに再びチューブ２の表面へ拡散される。したがって、抗菌成分１０として不揮発性で化学的に安定な成分を用いることにより、抗菌成分１０がチューブ２の表面に維持され、チューブ２の表面全体にわたる持続的な抗菌機能の発揮が可能となる。 FIG. 3 shows a schematic longitudinal section in the vicinity of the lower end of the tube of the heat exchanger shown in FIG. 1 (A), and particularly shows the operation of the heat exchanger provided as an evaporator in the refrigeration circuit. Yes. In the heat exchanger 1 of FIG. 3, a heat insulating seal member 6 is provided near the lower end of the tube 2, and a water absorbent sheet base material 7 is interposed between the tube 2 and the heat insulating seal member 6. When the heat exchanger 1 as an evaporator is operated, the tube 2 is cooled by the evaporation heat of the refrigerant (heat exchange medium) flowing through the tube 2, and heat exchange with the air passing through the tube 2 (air cooling). And the condensed water 8 may condense on the surface of the tube 2. Since the condensed water 8 is cooled and does not easily evaporate, when the amount of condensation increases, a film-like water layer 9 composed of the condensed water 8 is formed on the surface of the tube 2. When the water layer 9 develops and its area widens and the lower end of the water layer 9 comes into contact with the water absorbent sheet base material 7, the antibacterial component 10 held on the water absorbent sheet base material 7 is eluted into the water layer 9. And diffused to the surface of the tube 2. When the antibacterial component 10 is non-volatile, when the heat exchanger 1 stops and the condensed water 8 and the water layer 9 evaporate, the diffused antibacterial component 10 remains on the surface of the tube 2, and the heat exchanger 1 When the water layer 9 composed of the condensed water 8 is formed by operating again, it is diffused again to the surface of the tube 2. Therefore, by using a non-volatile and chemically stable component as the antibacterial component 10, the antibacterial component 10 is maintained on the surface of the tube 2, and a continuous antibacterial function can be exhibited over the entire surface of the tube 2.
　図４は、図１（Ｂ）に示した熱交換器のチューブ上端部近傍部位における概略縦断面を 示しており、とくに、冷凍回路内において蒸発器として設けられた熱交換器の動作を示している。図４の熱交換器１において、チューブ２の上端部近傍には断熱シール部材６が備えられており、チューブ２および断熱シール部材６の間には吸水性シート基材７が介在されている。蒸発器としての熱交換器１が稼動すると、チューブ２内を流通する冷媒の蒸発熱によってチューブ２が冷却され、チューブ２の表面に凝縮水８が結露することがある。チューブ２上端部近傍において結露した凝縮水８が吸水性シート基材７に接触すると、吸水性シート基材７に保持された抗菌成分が凝縮水８に溶出する。吸水性シート基材７はチューブ２の上端部近傍に設けられており、かつ、水分を容易に放出可能であるため、抗菌成分１０を含有する凝縮水８ａは重力により吸水性シート基材７から速やかに放出され、チューブ２の表面を下方へ向かって滴下し、抗菌成分１０はチューブ２の表面全体へと拡散される。上述の図２の場合と同様、抗菌成分１０が不揮発性であった場合、拡散された抗菌成分１０は凝縮水８ａの蒸発によってチューブ２の表面へ残存する。したがって、抗菌成分１０として不揮発性で化学的に安定な成分を用いることにより、抗菌成分１０がチューブ２の表面に維持され、チューブ２の表面全体にわたる持続的な抗菌機能の発揮が可能となる。 FIG. 4 shows a schematic longitudinal section in the vicinity of the upper end of the tube of the heat exchanger shown in FIG. 1 (B), and particularly shows the operation of the heat exchanger provided as an evaporator in the refrigeration circuit. Yes. In the heat exchanger 1 of FIG. 4, a heat insulating seal member 6 is provided in the vicinity of the upper end portion of the tube 2, and a water absorbent sheet base material 7 is interposed between the tube 2 and the heat insulating seal member 6. When the heat exchanger 1 as an evaporator is operated, the tube 2 is cooled by the evaporation heat of the refrigerant flowing through the tube 2, and the condensed water 8 may be condensed on the surface of the tube 2. When the condensed water 8 condensed in the vicinity of the upper end portion of the tube 2 comes into contact with the water absorbent sheet base material 7, the antibacterial component held by the water absorbent sheet base material 7 is eluted into the condensed water 8. Since the water absorbent sheet base material 7 is provided in the vicinity of the upper end of the tube 2 and can easily release moisture, the condensed water 8a containing the antibacterial component 10 is separated from the water absorbent sheet base material 7 by gravity. The antibacterial component 10 is quickly released and dropped on the surface of the tube 2 downward, and the antimicrobial component 10 is diffused over the entire surface of the tube 2. As in the case of FIG. 2 described above, when the antibacterial component 10 is non-volatile, the diffused antibacterial component 10 remains on the surface of the tube 2 by evaporation of the condensed water 8a. Therefore, by using a non-volatile and chemically stable component as the antibacterial component 10, the antibacterial component 10 is maintained on the surface of the tube 2, and a continuous antibacterial function can be exhibited over the entire surface of the tube 2.
　本発明はあらゆる種類の熱交換器に適用可能であり、とくに、冷凍回路内に設けられた蒸発器として用いられて好適なものである。 The present invention can be applied to all kinds of heat exchangers, and is particularly suitable for use as an evaporator provided in a refrigeration circuit.
