Description
本発明は、輻射冷房に用いる冷却パネルであって、冷却されたパネル表面に結露を生じさせて除湿にも用いることが可能な冷却パネルに関するものである。 The present invention relates to a cooling panel used for radiation cooling, and relates to a cooling panel that can be used for dehumidification by causing condensation on a cooled panel surface.
従来、輻射冷房に用いられる冷却パネルは、冷却されたパネル表面からの輻射熱によって冷房を行っている。この種の冷却パネルとして、アルミニウム合金等の金属からなり輻射面を形成するパネル本体と、このパネル本体に密着して配設されその内部に熱媒体を柱通させる配管とを備えた構成が知られている。 Conventionally, cooling panels used for radiant cooling are cooled by radiant heat from the cooled panel surface. As this type of cooling panel, a configuration including a panel body made of a metal such as an aluminum alloy and forming a radiation surface, and a pipe arranged in close contact with the panel body and through which a heat medium passes through is known. It has been.
例えば特許文献１の構成においては、銅管と、表面側が平板状に形成されると共に、背部側には間隔をおいて銅管を圧入する凹溝を設けた単位輻射パネルと、該単位輻射パネルの背部側に係合して銅管を凹溝に押し付ける後ろパネルとを備えた構成が開示されている。 For example, in the configuration of Patent Document 1, a unit radiant panel having a copper tube, a front side formed in a flat plate shape, and a groove on the back side for press-fitting the copper tube with a space therebetween, and the unit radiant panel And a rear panel that engages the back side and presses the copper tube against the groove.
また、特許文献２の構成においては、上面（裏面）側には断面形状をＵ字型とする２本のパイプ受け部を相互に離隔して有し、且つ長さ方向に連続して設けられたパネル本体と、熱媒体を流通させる配管と、該配管をパイプ受け部に固定するパネル固定部材とを備え、該パイプ固定部材は、パイプに密接する円弧状の面と、パイプ受け部の突起に係合する係合部とを備えており、パイプをパイプ受け部に押圧してパイプ受け部に密着させる構成が開示されている。 Moreover, in the structure of patent document 2, it has two pipe receiving parts which make a cross-sectional shape U shape in the upper surface (back surface) side mutually apart, and is provided continuously in the length direction. A panel main body, a pipe for circulating the heat medium, and a panel fixing member for fixing the pipe to the pipe receiving portion. The pipe fixing member includes an arcuate surface that is in close contact with the pipe, and a projection of the pipe receiving portion. And an engaging portion that engages with the pipe receiving portion, and a configuration in which the pipe is pressed against the pipe receiving portion to be brought into close contact with the pipe receiving portion is disclosed.
しかしながら、特許文献１の構成おいては、銅管を凹溝に圧着させる後パネルと当該凹溝に収容された銅管との間に隙間が形成されるため、当該隙間から熱が逃げる所謂ヒートロスが発生する虞がある。 However, in the configuration of Patent Document 1, since a gap is formed between the rear panel that presses the copper tube into the groove and the copper tube accommodated in the groove, so-called heat loss in which heat escapes from the gap. May occur.
また、特許文献２の構成においては、パイプをパイプ受け部に圧着させるパイプ固定部材がパイプに密着する円弧状の面を備えているため、当パイプ固定部とパイプとの間に隙間は生じず、一見してヒートロスは抑制されているかに見える。しかしながら、当該パイプの上方は開放された空間となっており、パイプから放射状に伝熱されるにも拘らず下方の面以外の面が開放されているため、例えばパイプ内の熱媒体から上方に放射される熱を有効に利用することができないという問題がある。かかる問題は特許文献１の構成でも同様である。 Further, in the configuration of Patent Document 2, since the pipe fixing member that crimps the pipe to the pipe receiving portion has an arcuate surface that is in close contact with the pipe, there is no gap between the pipe fixing portion and the pipe. At first glance, it seems that heat loss is suppressed. However, the upper part of the pipe is an open space, and the surfaces other than the lower surface are opened despite the heat transferred radially from the pipe. For example, the pipe radiates upward from the heat medium in the pipe. There is a problem that the heat generated cannot be used effectively. This problem is the same in the configuration of Patent Document 1.
そこで、本発明は、配管に供給される熱媒体からの輻射熱をより効率的に利用することができる冷却パネルを提供することを目的とする。 Then, an object of this invention is to provide the cooling panel which can utilize more efficiently the radiant heat from the heat medium supplied to piping.

また上記構成に加えて、前記支持部は、前記中空部材と一体成形された第１のガイド部と、前記中空部材に対して着脱可能な第２のガイド部とを備え、第１のガイド部は、前記中空部材内において向かい合う一方の内壁面から他方の内壁面にわたって一体成形されており、第２のガイド部は、前記中空部材内において向かい合う一方の内壁面と他方の内壁面とに案内支持される着脱自在な部材として形成されていることが好ましい。 Further, in addition to the above configuration, the support portion includes a first guide portion integrally formed with the hollow member, and a second guide portion detachable from the hollow member, and the first guide portion Is integrally formed from one inner wall surface facing the other in the hollow member to the other inner wall surface, and the second guide portion is guided and supported by one inner wall surface and the other inner wall surface facing each other in the hollow member. It is preferably formed as a detachable member.
また上記構成に加えて、前記中空部材は、導電性軽金属の押出成形された一体成形品であることが好ましい。また、前記吸熱板の外形は、前記中空部材の端部が前記ガイド部材部分よりも細い先細り形状となっていることが好ましい。 Moreover, in addition to the said structure, it is preferable that the said hollow member is the integral molded product by which the electroconductive light metal was extrusion-molded. Moreover, it is preferable that the external shape of the said heat absorption board is a taper shape where the edge part of the said hollow member is thinner than the said guide member part.
これによれば、吸熱板は、外表面に後述するフィンが設けられた中空部材と、中空部材内にて配管を案内支持するガイド部材としての支持部を有している。そして、配管は外周面全体が吸熱板内の支持部周面と圧着して熱的に結合しており、熱伝導性の良い構成となっている。 According to this, the heat absorption plate has a hollow member in which fins described later are provided on the outer surface, and a support portion as a guide member that guides and supports the pipe within the hollow member. The entire outer peripheral surface of the pipe is crimped and thermally coupled to the peripheral surface of the support portion in the heat absorbing plate, and has a structure with good thermal conductivity.
また支持部は、中空部材と一体成形された第１のガイド部と、中空部材に対して着脱可能な第２のガイド部とからなっており、配管の組み付け作業がし易いようになっている。 Further, the support portion includes a first guide portion integrally formed with the hollow member and a second guide portion detachable with respect to the hollow member, so that the pipe can be easily assembled. .
また、第１のガイド部は、中空部材内において向かい合う、一方の内壁面から他方の内壁面にわたって一体成形されており、中空部材の剛性を高めるものとなっている。また、第２のガイド部も、中空部材内において向かい合う、一方の内壁面と他方の内壁面とに案内支持されるように構成されているので、着脱可能な構成でありつつも、中空部材の剛性アップに寄与するものとなっているのである。 Moreover, the 1st guide part is integrally molded from one inner wall surface facing the other in a hollow member to the other inner wall surface, and raises the rigidity of a hollow member.

Thereby, further weight reduction can be achieved while ensuring the strength. In particular, by forming a part or all of the hollow member and the guide member of the heat-absorbing plate by integral molding by extrusion, the hollow member is integrated without being divided, and the guide member becomes a reinforcing material. Increases strength. By increasing the strength by this integral molding, the hollow member and the guide member can be thinned. As a result, the heat conduction efficiency is improved and the weight can be further reduced. Furthermore, by making the end of the hollow member into a tapered shape, the design is enhanced, and the appearance can be improved as an interior of a part of a room or an ornament.
以下、図面を参照して、本発明の好適な実施の形態を例示的に詳しく説明する。 Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.
〔第１実施形態〕
図１は本発明の第１実施形態に係る冷却パネルの説明図であり、（ａ）は冷却パネルを構成する吸熱板の断面図、（ｂ）は冷却パネルの一構成例を示す模式斜視図である。図１に示すように、本実施形態に係る冷却パネル１は、多数枚の吸熱板３によって構成されるものである。このように前記吸熱板３を鉛直方向に多数枚並設することにより、鉛直方向上方から見た単位面積当たりの吸熱量を多くできる。なお、本実施形態では前記吸熱板３を鉛直方向に多数枚並設する構成を例示しているが、吸熱板の枚数や並べ方については用途に応じて適宜設定すればよく、前述の構成に限定されるものではない。図１（ｂ）では、多数枚の吸熱板からなる冷却パネルとして、各吸熱板を冷却パネル方向（多数枚からなる吸熱板の並び方向）に対して直交するように配置した構成を例示したが、これに限定されるものではない。例えば前記冷却パネル方向に対する吸熱板の角度を変えて吸熱板間を通る風の流れを変更するように構成しても良い。[First Embodiment]
1A and 1B are explanatory views of a cooling panel according to a first embodiment of the present invention, in which FIG. 1A is a cross-sectional view of an endothermic plate constituting the cooling panel, and FIG. 1B is a schematic perspective view showing one configuration example of the cooling panel. It is. As shown in FIG. 1, the cooling panel 1 according to the present embodiment includes a plurality of heat absorbing plates 3. Thus, by arranging a large number of the heat absorbing plates 3 in the vertical direction, the amount of heat absorbed per unit area as viewed from above in the vertical direction can be increased. In the present embodiment, a configuration in which a large number of the heat absorbing plates 3 are arranged in the vertical direction is illustrated, but the number and arrangement of the heat absorbing plates may be appropriately set according to the application, and are limited to the above-described configuration. Is not to be done. In FIG. 1 (b), as the cooling panel made up of a large number of heat absorbing plates, a configuration in which the respective heat absorbing plates are arranged so as to be orthogonal to the cooling panel direction (the direction in which the heat absorbing plates made up of a large number of sheets) is illustrated. However, the present invention is not limited to this. For example, the flow of wind passing between the heat absorption plates may be changed by changing the angle of the heat absorption plates with respect to the cooling panel direction.
この吸熱板３は、それぞれ吸熱板３内部に、熱媒体を循環させるための配管２を有している。本実施形態では前記配管２として銅管を用いているが、前記配管はこれに限定されるものではなく、例えばステンレス管や樹脂管など、熱伝導性や耐性などを加味して適宜用いれば良い。 Each of the heat absorbing plates 3 has a pipe 2 for circulating a heat medium inside the heat absorbing plate 3. In the present embodiment, a copper pipe is used as the pipe 2, but the pipe is not limited to this, and may be appropriately used in consideration of thermal conductivity, resistance, etc., such as a stainless pipe or a resin pipe. .
前記吸熱板３は、外表面に後述するフィン５が設けられた中空部材６と、前記中空部材６内にて前記配管２を案内支持するガイド部材としての支持部４を有している。そして、前記配管２は外周面全体が前記吸熱板３内の支持部４周面と圧着して熱的に結合しており、熱伝導性の良い構成となっている。この配管２を有する吸熱板３を、図１（ｂ）に示すように鉛直方向に多数枚並設することで、本実施形態に係る冷却パネル１は構成される。 The heat absorbing plate 3 has a hollow member 6 provided with fins 5 to be described later on the outer surface, and a support portion 4 as a guide member for guiding and supporting the pipe 2 in the hollow member 6. And the said piping 2 has the whole outer peripheral surface crimped | bonded and thermally couple | bonded with the surrounding surface of the support part 4 in the said heat | fever absorption plate 3, and has the structure with favorable heat conductivity. The cooling panel 1 according to this embodiment is configured by arranging a large number of heat absorbing plates 3 having the pipes 2 in the vertical direction as shown in FIG.
更に、図１に示すように、前記吸熱板３の外表面に、鉛直方向に連なる断面突起状のフィン５を多数設けている。そして、前記フィン５の突起先端頂部の構造を、結露水が水滴状に発生し、且つ発生水滴が太ることなく頂部を落下しやすい構造としている。すなわち、前記フィン５の突起先端頂部の幅ｗを、結露水が成長しやすく、しかもその結露水で成長した水滴が自重で滴下しやすい幅に設定している。 Furthermore, as shown in FIG. 1, a large number of fins 5 having cross-sectional protrusions that are continuous in the vertical direction are provided on the outer surface of the heat absorbing plate 3. And the structure of the protrusion tip top part of the said fin 5 is made into the structure where dew condensation water generate | occur | produces in the shape of a water droplet, and the top part is easy to fall, without the generated water droplet becoming fat. That is, the width w of the top end of the protrusion of the fin 5 is set to a width at which condensed water is likely to grow and water droplets grown with the condensed water are likely to be dripped by its own weight.
なお、前記フィン５の突起先端頂部の構造において、結露水が水滴状に発生することとは、前述の如く空気中の湿気（水蒸気）が冷却パネルのパネル表面（冷却面）に結露する、いわゆる水蒸気凝縮のうち、凝縮してできた液相の形状が滴状である滴状凝縮が発生することである。また発生水滴が太ることなくとは、前記滴状凝縮が進行することで生じた水滴は前記冷却面との接触角が大きいほど効率よく落下（滴下）するが、この滴下しやすい前記冷却面との接触角が保てないほど水滴が大きく成長しないということである。 In the structure of the tip of the projection of the fin 5, the generation of condensed water in the form of water droplets means that moisture (water vapor) in the air condenses on the panel surface (cooling surface) of the cooling panel as described above. In the steam condensation, a drop-like condensation is generated in which the liquid phase formed by the condensation has a drop-like shape. Also, the generated water droplets do not become thick, and the water droplets generated by the progress of the droplet condensation efficiently drop (drop) as the contact angle with the cooling surface increases. This means that the water droplets do not grow so large that the contact angle cannot be maintained.
具体的には、前記結露水が水滴状に発生し、且つ発生水滴が太ることなく頂部を落下しやすい、前記フィン５の突起先端頂部の構造として、前記フィン５の突起先端頂部の幅ｗを１．５ｍｍ以上としている。更には前記フィン５の突起先端頂部の幅ｗを２．０ｍｍ以上とすることが好ましい。また、前記フィン５の突起先端頂部の幅ｗを６．０ｍｍ以下とすることが好ましく、更には４．０ｍｍ以下とすることが好ましい。なお、前記フィン５の突起先端頂部の幅ｗを、好ましくは２．０ｍｍ〜４．０ｍｍとしたことの根拠については、後述する実験およびその結果を用いて説明する。 Specifically, the width w of the protrusion tip apex of the fin 5 is the structure of the protrusion tip apex of the fin 5 in which the condensed water is generated in the form of water droplets and the generated water droplets are easy to fall without getting thick. It is 1.5 mm or more. Furthermore, it is preferable that the width w of the top end of the protrusion of the fin 5 is 2.0 mm or more. In addition, the width w of the tip end of the protrusion of the fin 5 is preferably 6.0 mm or less, and more preferably 4.0 mm or less. In addition, the grounds that the width w of the top end of the protrusion of the fin 5 is preferably set to 2.0 mm to 4.0 mm will be described using experiments and results described later.
また、熱伝導性および滴下効率の良さを考慮して、前記吸熱板３は導電性軽金属の押出成形品であることが好ましい。本実施形態では、導電性軽金属の１つであるアルミニウムを用い、前記吸熱板３を前記アルミニウムの押出成形品としている。これにより、熱伝導性が良く、かつ軽量でハンドリング性が良く、更に安価に提供できる。しかも間仕切り等の建築エレメントと一体となった冷却装置が提供可能である。なお、本実施形態では、導電性軽金属としてアルミニウムを例示したが、本発明はこれに限定されるものではない。 In consideration of good thermal conductivity and dropping efficiency, the heat absorbing plate 3 is preferably an extruded product of conductive light metal. In this embodiment, aluminum which is one of conductive light metals is used, and the heat absorbing plate 3 is an extruded product of the aluminum. Thereby, heat conductivity is good, and it is lightweight, it is easy to handle, and can be provided at a lower cost. Moreover, it is possible to provide a cooling device integrated with a building element such as a partition. In the present embodiment, aluminum is exemplified as the conductive light metal, but the present invention is not limited to this.
次に、図２及び図３を参照して、前記フィン５の突起先端頂部の構造について、実施例と比較例とを用いて詳しく説明する。 Next, with reference to FIGS. 2 and 3, the structure of the top end of the protrusion of the fin 5 will be described in detail using examples and comparative examples.
図２（ａ）に示す実施例に係る吸熱板１０と、図２（ｂ）に示す比較例としての吸熱板２０とを用いて、同条件の結露発生雰囲気下で、水滴流下状況を観察した。詳しくは各吸熱板の下部に滴下した水滴を貯水し、その貯水量を測定した。 Using the heat-absorbing plate 10 according to the example shown in FIG. 2A and the heat-absorbing plate 20 as a comparative example shown in FIG. . Specifically, water drops dripped at the lower part of each heat absorbing plate were stored, and the amount of stored water was measured.
両吸熱板１０，２０は、図２（ａ），（ｂ）に示すように、同サイズのアルミ板材１１，２１にチャンネル形材１２，２２を各ピッチ間隔で取り付けたものを用いた。また、これら吸熱板１０，２０は、有効結露部以外は吸湿材を貼り付けた。さらに、アルミ板材１１，２１と各チャンネル形材１２，２２との接合部は密着させている。 As shown in FIGS. 2A and 2B, the two endothermic plates 10 and 20 were obtained by attaching channel shape members 12 and 22 to the same size aluminum plate members 11 and 21 at respective pitch intervals. Further, the heat absorbing plates 10 and 20 were bonded with a hygroscopic material except for the effective dew condensation portion. Further, the joints between the aluminum plate members 11 and 21 and the channel members 12 and 22 are in close contact with each other.
図２（ａ）に示すように、実施例に係る吸熱板１０は、前記チャンネル形材１２による複数フィン１２ａの一方端部から他方端部までの長さｌが９２ｍｍ、各フィン１２ａの高さｈが２０ｍｍ、フィン１２ａ同士の間隔ｔが１６ｍｍ、フィン１２ａの突起先端頂部の幅ｗが２ｍｍである。この実施例に係る吸熱板１０の有効結露表面積は０．４２０３ｍ２である。As shown in FIG. 2A, in the heat absorbing plate 10 according to the embodiment, the length l from one end to the other end of the plurality of fins 12a by the channel shape member 12 is 92 mm, and the height of each fin 12a. h is 20 mm, the interval t between the fins 12 a is 16 mm, and the width w of the top end of the protrusion of the fin 12 a is 2 mm. The effective dew condensation surface area of the heat absorbing plate 10 according to this embodiment is 0.4203 m 2 .
一方、比較例としての吸熱板２０は、前記チャンネル形材２２による複数フィン２２ａの一方端部から他方端部までの長さｌが９９ｍｍ、各フィン２２ａの高さｈが２０ｍｍ、フィン２２ａ同士の間隔ｔが１３ｍｍ、フィン２２ａの突起先端頂部の幅ｗが１ｍｍである。この比較例に係る吸熱板２０の有効結露表面積は０．５５７２５ｍ２である。On the other hand, the heat absorbing plate 20 as a comparative example has a length l from one end to the other end of the plurality of fins 22a of the channel shape member 22 of 99 mm, the height h of each fin 22a is 20 mm, and the fins 22a The interval t is 13 mm, and the width w of the top end of the protrusion of the fin 22a is 1 mm. The effective dew condensation surface area of the heat absorbing plate 20 according to this comparative example is 0.55725 m 2 .
実験方法は、図２（ｃ）に示す簡易断熱試験装置３０に、前述の吸熱板１０，２０を順に設置し、同条件の結露発生雰囲気下で、滴下し貯水した水の貯水量を測定する。試験装置は、吸熱板１０，２０を取り付ける仕切壁３１に仕切られた、一方の室が低温室３２、他方の室が高温室３３となっている。前記吸熱板１０，２０は、フィンが設けられた面が高温室３３側に向くように前記仕切壁３１に取り付ける。 In the experimental method, the heat absorbing plates 10 and 20 are sequentially installed in the simple heat insulation test apparatus 30 shown in FIG. 2 (c), and the amount of water stored by dripping and storing in the condensation generation atmosphere under the same conditions is measured. . In the test apparatus, one chamber is a low temperature chamber 32 and the other chamber is a high temperature chamber 33 partitioned by a partition wall 31 to which the heat absorbing plates 10 and 20 are attached. The heat absorbing plates 10 and 20 are attached to the partition wall 31 so that the surface on which the fins are provided faces the high temperature chamber 33 side.
そして、試験装置３０の環境設定条件は、低温側の温度を０℃、高温側（結露発生側）の温度を３０℃、湿度を７０％として、３時間加湿を行い、前述の貯水量の測定を行った。 The environment setting conditions of the test apparatus 30 are as follows: the temperature on the low temperature side is 0 ° C., the temperature on the high temperature side (condensation generation side) is 30 ° C., the humidity is 70%, and humidification is performed for 3 hours. Went.
前述の実験の結果、実施例に係る吸熱板１０の貯水量は１００．３ｇであり、比較例に係る吸熱板２０の貯水量は７９．８ｇであった。この結果から、フィンの突起先端頂部の幅ｗが２ｍｍである実施例の方が、同幅ｗが１ｍｍである比較例よりも、有効結露表面積が小さいにもかかわらず、除湿効果が高い（貯水量が多い）ことがわかった。 As a result of the above-described experiment, the amount of water stored in the heat sink plate 10 according to the example was 100.3 g, and the amount of water stored in the heat sink plate 20 according to the comparative example was 79.8 g. From this result, the example in which the width w of the tip end of the projection of the fin is 2 mm has a higher dehumidifying effect than the comparative example in which the width w is 1 mm, although the effective dew condensation surface area is small (water storage It was found that the amount was large).
結露の成長の仕方として、フィンの突起先端頂部から成長し、流下し始める。従って、前記フィン先端頂部の幅ｗが２ｍｍである実施例の方が、同幅ｗが１ｍｍである比較例よりも前記幅ｗが厚く、冷やされたフィン先端頂部が湿気を含んだ空気に触れる面積が大きくなってるため、より結露の成長を助長させていると考えられる。 As a method of growth of condensation, it grows from the top of the tip of the fin protrusion and starts to flow down. Therefore, in the embodiment in which the width w of the tip end of the fin is 2 mm, the width w is thicker than the comparative example in which the width w is 1 mm, and the cooled tip end of the fin touches the air containing moisture. It is thought that the growth of condensation is further promoted because the area increases.
また、結露の発生量は理論的には湿気を含んだ空気と触れ合う表面積（有効結露表面積）を多くとることが有効であると思われたが、上記実験結果では、フィンの突起先端頂部の幅ｗが２ｍｍである実施例の方が、同幅ｗが１ｍｍである比較例よりも、有効結露表面積が小さいにもかかわらず、貯水量が多かったことから、前記フィンの突起先端頂部の幅を２ｍｍ以上とすることが、結露水が水滴状に発生し、且つ発生水滴が太ることなく頂部を落下しやすくする構造として有効であることがわかる。 In addition, it seems that it is effective to increase the surface area (effective condensation surface area) in contact with moisture-containing air theoretically. However, in the above experimental results, the width of the top of the tip of the fin protrusion is considered to be effective. In the example where w is 2 mm, the amount of stored water was larger in spite of the smaller effective condensation surface area than in the comparative example where the same width w was 1 mm. It can be seen that the thickness of 2 mm or more is effective as a structure in which dew condensation water is generated in the form of water droplets and the top is easily dropped without the generated water droplets becoming thick.
なお、前述の実験時の各吸熱板１０，２０の結露状況を図３に示す。図３（ａ）は実施例に係る吸熱板１０の結露状況を示す図であり、図３（ｂ）は比較例に係る吸熱板２０の結露状況を示す図である。図３（ａ）に示す実施例に係る吸熱板１０の方が、図３（ｂ）に示す比較例に係る吸熱板２０よりも、チャンネル形材１２によるフィン１２ａの突起先端頂部で結露している水滴が少なく、フィン先端頂部での流下量が多いことがわかる。 In addition, the dew condensation state of each heat sink plate 10 and 20 at the time of the above-mentioned experiment is shown in FIG. FIG. 3A is a diagram illustrating the dew condensation state of the heat absorption plate 10 according to the embodiment, and FIG. 3B is a diagram illustrating the dew condensation state of the heat absorption plate 20 according to the comparative example. The heat absorption plate 10 according to the embodiment shown in FIG. 3A is condensed at the top of the tip of the projection of the fin 12a by the channel shape member 12 than the heat absorption plate 20 according to the comparative example shown in FIG. It can be seen that there are few water droplets and the amount of flow at the top of the fin tip is large.
上述したように、本実施形態によれば、吸熱板の表面積（有効結露表面積）を多くするために多数のフィンを設けただけでなく、更に前記フィンの突起先端頂部の構造を、結露水が水滴状に発生し、且つ発生水滴が太ることなく頂部を落下しやすい構造としている。具体的には前記フィンの突起先端頂部の幅を１．５ｍｍ以上とし、更に好ましくは前記フィンの突起先端頂部の幅を２．０ｍｍ以上としている。これにより、前記フィンの突起先端頂部では、結露（滴状凝縮）が発生しやすく且つ該結露が成長しやすく、しかもその結露で成長した水滴が自重で滴下しやすい。つまり、フィンの突起先端頂部に水滴が付着している時間が短いのである。すなわち、フィンの突起先端頂部が、常に結露しやすい室温との温度差を有する状態に保たれており、上述の貯水量が多かったことからもわかるように、除湿の効果が高い。さらにそれだけではなく、フィンの突起先端頂部が、室温との温度差を有する状態に保たれてことからもわかるように、本冷却パネルは輻射による冷房効果も高い状態で維持されているのである。 As described above, according to the present embodiment, not only a large number of fins are provided in order to increase the surface area (effective condensation surface area) of the heat absorbing plate, but also the structure of the top end of the protrusion tip of the fins It has a structure that is generated in the form of water droplets and is easy to fall without causing the generated water droplets to thicken. Specifically, the width of the top of the protrusion tip of the fin is 1.5 mm or more, and more preferably the width of the top of the protrusion tip of the fin is 2.0 mm or more. As a result, condensation (drop-like condensation) is likely to occur at the top of the tip of the projection of the fin, and the condensation is likely to grow, and water droplets grown by the condensation are likely to be dripped by its own weight. That is, the time during which water droplets are attached to the top of the projection tip of the fin is short. That is, the tip end of the fin protrusion always maintains a temperature difference from room temperature at which condensation easily occurs, and the dehumidifying effect is high, as can be seen from the fact that the amount of stored water was large. Furthermore, as can be seen from the fact that the tops of the tips of the protrusions of the fins are kept in a state having a temperature difference from room temperature, the cooling panel is maintained in a state where the cooling effect by radiation is also high.

図４及び図５は本発明の第２実施形態に係る冷却パネルを構成する吸熱板の説明図である。図４は吸熱板の断面図である。図５において、（ａ）は吸熱板のＡ−Ａ断面図、（ｂ）は吸熱板の側面図、（ｃ）は吸熱板の端部正面図である。[Second Embodiment]
4 and 5 are explanatory views of a heat absorbing plate constituting the cooling panel according to the second embodiment of the present invention. FIG. 4 is a sectional view of the heat absorbing plate. In FIG. 5, (a) is an AA cross-sectional view of the endothermic plate, (b) is a side view of the endothermic plate, and (c) is an end front view of the endothermic plate.
なお、本実施形態に係る吸熱板を鉛直方向に多数枚並設することにより、前述した第１実施形態と同様に冷却パネルを構成することは可能である。このように吸熱板を鉛直方向に多数枚並設することにより、鉛直方向上方から見た単位面積当たりの吸熱量を多くできる。なお、ここでは吸熱板を鉛直方向に多数枚並設する構成を例示しているが、吸熱板の枚数や並べ方については用途に応じて適宜設定すればよく、前述の構成に限定されるものではない。 In addition, it is possible to comprise a cooling panel similarly to 1st Embodiment mentioned above by arranging many heat absorption plates which concern on this embodiment in the perpendicular direction. By arranging a large number of heat absorbing plates in the vertical direction in this way, the amount of heat absorbed per unit area as viewed from above in the vertical direction can be increased. Note that, here, a configuration in which a large number of endothermic plates are arranged in the vertical direction is illustrated, but the number and arrangement of the endothermic plates may be appropriately set according to the application, and are not limited to the above configuration. Absent.
以下、図４及び図５を用いて本実施形態に係る冷却パネルを構成する吸熱板について説明する。なお、本実施形態における吸熱板において、前述した第１実施形態における吸熱板と同等の機能を有する部材には同一符号を付している。 Hereinafter, the heat absorbing plate constituting the cooling panel according to the present embodiment will be described with reference to FIGS. 4 and 5. In addition, in the heat sink in this embodiment, the same code | symbol is attached | subjected to the member which has a function equivalent to the heat sink in 1st Embodiment mentioned above.
図４及び図５に示すように、吸熱板３は、それぞれ吸熱板３内部に、熱媒体を循環させるための配管２を有している。本実施形態では前記配管２として樹脂製の配管を用いている。このように樹脂製の配管を用いることにより、屈曲性が良く、小半径に曲げることができ、配管の加工、吸熱板への配管の組み付け作業が容易となる。また配管同士の接続も容易にできる。更に吸熱板の幅を狭くすることも可能である。 As shown in FIGS. 4 and 5, the endothermic plate 3 has a pipe 2 for circulating a heat medium inside the endothermic plate 3. In the present embodiment, a resin pipe is used as the pipe 2. By using the resin pipe in this way, the flexibility is good, the pipe can be bent to a small radius, and the processing of the pipe and the work of assembling the pipe to the heat absorption plate are facilitated. In addition, the pipes can be easily connected. Further, the width of the heat absorbing plate can be reduced.
更に前記配管２として樹脂製の配管を用いることで、配管２内の熱媒体の循環を損なわない程度に、吸熱板の厚さ方向に、配管２を断面を扁平に加工することも可能である。この場合、吸熱板の厚さ方向に配管２を平たく加工するため、吸熱板２の厚さを薄くできるだけでなく、吸熱板３（中空部材６）と配管２との接触面積を増やすことができ、熱伝導性を向上させることができる。 Further, by using a resin pipe as the pipe 2, it is possible to process the pipe 2 into a flat cross section in the thickness direction of the heat absorbing plate so as not to impair the circulation of the heat medium in the pipe 2. . In this case, since the pipe 2 is processed flat in the thickness direction of the heat absorbing plate, not only the thickness of the heat absorbing plate 2 can be reduced, but also the contact area between the heat absorbing plate 3 (hollow member 6) and the pipe 2 can be increased. , Heat conductivity can be improved.
また配管２は前述の樹脂製の配管に限定されるものではなく、熱伝導性や耐性、更には加工や組み付け作業の容易性などを加味して適宜用いれば良い。例えば前述した実施形態のように金属製の配管を用いても良いし、或いは樹脂製の配管であっても、金属強化ポリエチレン管などの金属の補強層を有する架橋ポレオレフィン樹脂管を用いても良い。特に、金属の補強層を有する架橋ポレオレフィン樹脂管を用いた場合、前述の効果に加えて更に、配管の加工が容易であるだけでなく、曲げなどの加工状態を維持することができるため、作業性が更に向上する。また金属補強により更なる強度アップも図れる。また金属層を有するので熱伝導性や耐性を更に高めることができ、金属補強による強度アップにより管を肉薄にでき、その結果熱伝導が更に良くなる。 The pipe 2 is not limited to the above-described resin pipe, and may be used as appropriate in consideration of thermal conductivity and resistance, and ease of processing and assembly work. For example, a metal pipe may be used as in the above-described embodiment, or a resin pipe or a crosslinked polyolefin resin pipe having a metal reinforcing layer such as a metal reinforced polyethylene pipe may be used. good. In particular, when a crosslinked polyolefin resin tube having a metal reinforcing layer is used, in addition to the above-described effects, not only the processing of the piping is easy, but also the processing state such as bending can be maintained. Workability is further improved. Moreover, the strength can be further increased by metal reinforcement. In addition, since the metal layer is provided, the thermal conductivity and resistance can be further increased, and the tube can be thinned by increasing the strength by reinforcing the metal, and as a result, the heat conduction is further improved.
また図４及び図５に示すように、吸熱板３は、外表面に後述するフィン５が設けられた中空部材６と、前記中空部材６内にて前記配管２を案内支持するガイド部材としての支持部４を有している。本実施形態に係る吸熱板３は、中空部材６と支持部４を一体成形している。 As shown in FIGS. 4 and 5, the heat absorbing plate 3 includes a hollow member 6 provided with fins 5 to be described later on the outer surface, and a guide member that guides and supports the pipe 2 within the hollow member 6. A support part 4 is provided. In the heat absorbing plate 3 according to the present embodiment, the hollow member 6 and the support portion 4 are integrally formed.
更に吸熱板３は、その外形が、水平断面形状が扁平であり、端部６ａが中央部６ｂよりも細い先細り形状に形成されている。具体的には、例えば図４に示すように、中空部材６の端部６ａが支持部４が設けられたガイド部材部分６ｃよりも細い先細り形状に形成されている。 Further, the heat absorbing plate 3 is formed in a tapered shape whose outer cross section is flat in horizontal cross section and whose end 6a is thinner than the central portion 6b. Specifically, for example, as shown in FIG. 4, the end 6 a of the hollow member 6 is formed in a tapered shape that is narrower than the guide member portion 6 c provided with the support 4.
また前記支持部４は、配管２の組み付け作業がし易いように、中空部材６と一体成形された第１のガイド部４ａと、中空部材６に対して着脱可能な第２のガイド部４ｂとからなる。第１のガイド部４ａは、中空部材６の剛性を高めるために、中空部材６内において向かい合う、一方の内壁面から他方の内壁面にわたって一体成形されている。また、第２のガイド部４ｂも、着脱可能な構成ではあるものの、中空部材６の剛性アップに寄与するために、中空部材６内において向かい合う、一方の内壁面と他方の内壁面とに案内支持されるように構成されている。 The support portion 4 includes a first guide portion 4a formed integrally with the hollow member 6 and a second guide portion 4b detachable from the hollow member 6 so that the pipe 2 can be easily assembled. Consists of. In order to increase the rigidity of the hollow member 6, the first guide portion 4 a is integrally formed from one inner wall surface facing the other inside the hollow member 6 to the other inner wall surface. Although the second guide portion 4b is also detachable, the second guide portion 4b is guided and supported by one inner wall surface and the other inner wall surface facing each other in the hollow member 6 in order to contribute to increasing the rigidity of the hollow member 6. It is configured to be.
そして、前記配管２は前記支持部４内に挿入され支持される。この配管２は外周面全体が前記吸熱板３内の支持部４周面と接して熱的に結合しており、熱伝導性の良い構成となっている。 The pipe 2 is inserted and supported in the support portion 4. The entire outer peripheral surface of the pipe 2 is in thermal contact with the peripheral surface of the support portion 4 in the heat absorbing plate 3 and has a good thermal conductivity.
なお、本実施形態における吸熱板３のフィン５も、前述した実施形態における吸熱板のフィンと同様に設けられている。すなわち、中空部材６の外表面に、鉛直方向に連なる断面突起状のフィン５が多数設けられている。なお、このフィン５の突起先端頂部の構造は、前述した実施形態と同様であるため、その説明を援用するものとし、ここでは詳しい説明は省略する。 In addition, the fin 5 of the heat sink 3 in this embodiment is also provided similarly to the fin of the heat sink in the above-described embodiment. In other words, the outer surface of the hollow member 6 is provided with a large number of fins 5 having cross-sectional protrusions that are continuous in the vertical direction. In addition, since the structure of the protrusion front-end | tip part of this fin 5 is the same as that of embodiment mentioned above, the description shall be used and detailed description is abbreviate | omitted here.
本実施形態における吸熱板３は、強度アップおよび軽量化の観点から一体成形品となっているが、更に熱伝導性および滴下効率の良さを考慮して、前記吸熱板３はアルミニウムなどの導電性軽金属の押出成形品であることが好ましい。これにより、強度アップが図れ、熱伝導性が良く、かつ軽量でハンドリング性が良く、更に安価に提供できる。また、一体成形による強度アップにより、中空部材６及び支持部４を肉薄にでき、その結果、熱伝導効率が良くなり、更なる軽量化も図れる。しかも間仕切り等の建築エレメントと一体となった冷却装置が提供可能である。更には、吸熱板の端部は、前述したように先細り形状となっているため、意匠性が高くなり、部屋の一部または置物などのインテリアとして美観を向上させることもできる。なお、ここでは、導電性軽金属としてアルミニウムを例示したが、本発明はこれに限定されるものではない。 The endothermic plate 3 in the present embodiment is an integrally molded product from the viewpoint of increasing strength and reducing the weight, but the endothermic plate 3 is made of a conductive material such as aluminum in consideration of thermal conductivity and good dropping efficiency. A light metal extruded product is preferred. As a result, the strength can be increased, the thermal conductivity is good, the weight is low, the handling property is good, and the cost can be further reduced. Moreover, the hollow member 6 and the support part 4 can be made thin by the strength improvement by integral molding, As a result, heat conduction efficiency improves and the further weight reduction can also be achieved. Moreover, it is possible to provide a cooling device integrated with a building element such as a partition. Furthermore, since the end portion of the endothermic plate has a tapered shape as described above, the design is enhanced, and the appearance can be improved as an interior of a part of a room or an ornament. In addition, although aluminum was illustrated here as an electroconductive light metal, this invention is not limited to this.
本実施形態における吸熱板３は、中空部材６に多数のフィン５が設けられているが、端部６ａの一部と、中央部６ｂの一部にはフィン５を設けていない。端部６ａの一部にフィン５を設けないことにより、更に意匠性が高まり、且つ吸熱板３をより細く且つ薄く見せる視覚効果が得られる。また、中央部６ｂの一部にフィン５を設けないのは、吸熱板３を並設して冷却パネルを構成する際に、吸熱板３同士を連結部材によって連結し易くするためである。 In the heat absorbing plate 3 in the present embodiment, the fins 5 are provided in the hollow member 6, but the fins 5 are not provided in a part of the end 6 a and a part of the central part 6 b. By not providing the fin 5 at a part of the end portion 6a, the design effect is further enhanced, and the visual effect of making the heat absorbing plate 3 thinner and thinner can be obtained. The reason why the fins 5 are not provided in a part of the central portion 6b is to make it easy to connect the endothermic plates 3 with each other when the endothermic plates 3 are arranged in parallel to form a cooling panel.
上述したように、本実施形態によれば、冷却パネルを構成する吸熱板３を、前述の中空部材６と支持部４を有する構成とし、更に前記中空部材６の端部６ａを前記支持部４が設けられたガイド部材部分６ｃよりも細い先細り形状としている。これにより、前述した実施形態と同様の効果が得られるだけでなく、強度を確保しつつ、更なる軽量化が図れる。特に前記吸熱板３を押出一体成形品とすることにより、更なる強度アップが図れる。更に一体成形による強度アップにより、中空部材６及び支持部４を肉薄にでき、その結果、更なる軽量化も図れる。更に、前記中空部材６の端部６ａを先細り形状とすることにより、意匠性が高くなり、部屋の一部または置物などのインテリアとして美観を向上させることができる。 As described above, according to the present embodiment, the heat absorbing plate 3 constituting the cooling panel is configured to include the hollow member 6 and the support portion 4 described above, and the end 6 a of the hollow member 6 is further connected to the support portion 4. It is made into the taper shape thinner than the guide member part 6c provided. As a result, the same effects as those of the above-described embodiment can be obtained, and further weight reduction can be achieved while securing the strength. In particular, by using the heat absorbing plate 3 as an integrally formed extrusion product, the strength can be further increased. Furthermore, the hollow member 6 and the support part 4 can be made thin by strength improvement by integral molding, and as a result, further weight reduction can be achieved. Furthermore, by making the end 6a of the hollow member 6 into a tapered shape, the design is enhanced, and the appearance can be improved as an interior of a part of a room or an ornament.
また、前記配管２として、樹脂製の配管を用いることにより、屈曲性が良く、小半径に曲げることができ、配管の加工、吸熱板への配管の組み付け作業が容易となる。また配管同士の接続も容易にできる。更に吸熱板の幅を狭くすることも可能である。 Further, by using a resin pipe as the pipe 2, the pipe 2 has good flexibility and can be bent to a small radius, thereby facilitating the pipe processing and the pipe assembling work to the heat absorbing plate. In addition, the pipes can be easily connected. Further, the width of the heat absorbing plate can be reduced.
あるいは、前記配管２として、金属の補強層を有する架橋ポレオレフィン樹脂製の配管を用いることにより、前述の効果に加えて更に、配管の加工が容易であるだけでなく、曲げなどの加工状態を維持することができるため、作業性が更に向上する。また金属補強により更なる強度アップも図れる。また金属層を有するので熱伝導性や耐性を更に高めることができ、金属補強による強度アップにより管を肉薄にでき、その結果熱伝導が更に良くなる。 Alternatively, by using a pipe made of a crosslinked polyolefin resin having a metal reinforcing layer as the pipe 2, in addition to the effects described above, the pipe is not only easily processed but also has a working state such as bending. Since it can maintain, workability | operativity improves further. Moreover, the strength can be further increased by metal reinforcement. In addition, since the metal layer is provided, the thermal conductivity and resistance can be further increased, and the tube can be thinned by increasing the strength by reinforcing the metal, and as a result, the heat conduction is further improved.
上記第１、第２実施形態における冷房パネルの好適な適用例は、冷却パネルの熱媒体循環用の配管を地下３〜５ｍ以下の地中温度が一定した部分を通過する配管と接続し、循環ポンプで熱媒体である水を循環させるだけという極めて簡易な冷房機器にすることである。 A preferable application example of the cooling panel in the first and second embodiments is to connect a piping for circulating the heat medium of the cooling panel to a piping passing through a portion where the underground temperature of 3 to 5 m or below is constant. It is to make a very simple cooling device that only circulates water as a heat medium with a pump.
〔他の実施形態〕
上述した吸熱板を用いた冷却パネルは、クーラーなどの冷房機器に用いる冷媒や熱交換器を用いて、冷房機器として用いることが可能である。また、配管を循環させる熱媒体を冷やされた熱媒体から暖められた熱媒体に代えることで、暖房機器として用いることも可能である。[Other Embodiments]
The cooling panel using the above-described heat absorbing plate can be used as a cooling device using a refrigerant or a heat exchanger used in a cooling device such as a cooler. Moreover, it can also be used as a heating device by replacing the heat medium circulating in the piping with a heated heat medium from a cooled heat medium.
また、地中に埋設した熱媒体循環用の配管や、ヒートポンプを有する熱交換ユニットなどを備えた地中熱利用冷暖房システムにおいて、上述した吸熱板を用いた冷却パネルを利用することで、除湿機能を備えた冷暖房機器として用いることが可能である。 Also, in the underground heat utilization cooling and heating system equipped with a heat medium circulation pipe buried in the ground, a heat exchange unit having a heat pump, etc., the dehumidifying function is achieved by using the cooling panel using the above-described heat absorbing plate. It is possible to use as an air conditioning apparatus provided with.
地中熱利用冷暖房システムを利用した冷暖房機器としては、暖房にのみ用いる輻射系の床暖房パネル、冷暖房に用いるファンコイルユニットを併用する構成が知られている。しかしながら、送風機能を有する冷房機器（ファンコイルユニット）では、例えば帰宅直後の暑いときなどは冷気の送風は心地よいが、一旦涼しくなると、その送風がかえって不快になる場合がある。これに対し、輻射系の冷房機器（冷却パネル）は送風しないので、冷気の心地よさを長時間にわたって維持できる。なお、輻射系の床暖房パネルに冷やされた熱媒体を循環させることで冷房機器として用いることは可能であるが、床暖房パネルは人が直接触れる機器であるため、結露対策として、センサーで露点温度を感知して前述の結露を生じさせないように運転を制御する技術が必要となり、本実施形態に係る冷却パネルに比べてコストがかかる。 2. Description of the Related Art As a cooling / heating device using a geothermal heating / cooling system, a configuration in which a radiation-type floor heating panel used only for heating and a fan coil unit used for cooling / heating are used in combination is known. However, in a cooling device (fan coil unit) having a blowing function, for example, when it is hot immediately after returning home, the blowing of cool air is comfortable, but once it cools down, the blowing may change and become uncomfortable. On the other hand, since the radiant cooling device (cooling panel) does not blow air, the comfort of cold air can be maintained for a long time. Although it is possible to use it as a cooling device by circulating a chilled heat medium through the radiant floor heating panel, the floor heating panel is a device that is directly touched by humans. A technique for controlling the operation so as not to cause the above-mentioned condensation by sensing the temperature is required, which is more expensive than the cooling panel according to the present embodiment.
このようなことから、床暖房パネルとファンコイルユニットを併用することなく、前述した冷却パネル１を地中熱利用冷暖房システムと組み合わせることで、心地よさだけでなく、コスト的にも２４時間利用可能な快適な冷暖房が可能である。 For this reason, it is possible to use not only comfort but also 24 hours in terms of cost by combining the above-described cooling panel 1 with an underground heating / cooling system without using a floor heating panel and a fan coil unit. Comfortable air conditioning is possible.
なお、前記冷却パネルを暖房機器として利用する場合は熱交換ユニットを介して熱媒体を循環させ、冷房機器（あるいは除湿機器）として利用する場合は熱交換ユニットを介して熱媒体を循環させても良いし、或いは地中に埋設した配管から熱媒体を直接循環させても良い。ここで、冷却パネルを暖房に用いる場合、所定の強度が求められる床に設けられる床暖房パネルと比べて、冷却パネルは室内に露出させることが可能であるため、循環させる熱媒体の温度が、床暖房パネルに比べて低くて良い。このため、同様に地熱を利用した輻射系の機器であっても、冷却パネルの方が運転コストが安い。 When the cooling panel is used as a heating device, the heat medium is circulated through a heat exchange unit. When the cooling panel is used as a cooling device (or a dehumidifying device), the heat medium is circulated through a heat exchange unit. Alternatively, the heat medium may be directly circulated from a pipe buried in the ground. Here, when the cooling panel is used for heating, compared to the floor heating panel provided on the floor where a predetermined strength is required, the cooling panel can be exposed indoors, so the temperature of the circulating heat medium is Lower than floor heating panel. For this reason, even if it is a radiation type | system | group apparatus using geothermal similarly, the operation cost of the cooling panel is cheaper.
なお、前述した実施形態では、吸熱板の外形が、水平断面形状が扁平であり、端部が中央部よりも細い先細り形状である構成として、図４に示すように、吸熱板の水平断面が２つの円弧を向かい合わせたような略楕円状の形状を例示したが、本発明はこれに限定されるものではない。 In the above-described embodiment, the outer shape of the heat absorbing plate is configured such that the horizontal cross-sectional shape is flat and the end is a tapered shape that is thinner than the central portion, as shown in FIG. Although a substantially elliptical shape in which two arcs face each other is illustrated, the present invention is not limited to this.
また、前述した実施形態では、吸熱板が、配管を案内支持するガイド部材（支持部）として、配管２の外周面全体を覆う構成のガイド部材を例示した。すなわち、前記ガイド部材は、吸熱板における中空部材内で熱媒体が循環する配管が暴れないように、且つ中空部材と配管とが常に当接（或いは圧接）するように、配管を案内支持できるように設けてある。 Moreover, in embodiment mentioned above, the heat absorption board illustrated the guide member of the structure which covers the whole outer peripheral surface of the piping 2 as a guide member (support part) which guides and supports piping . That is, the guide member so as not rage piping heat medium is circulated in the hollow member in the endothermic board, and as a hollow member pipe and is always abuts (or pressure), so that it can guide and support the pipe Oh Ru provided.
また、吸熱板が有する配管の本数は、必要に応じて適宜設定されるものであって、前述した形態に限定されるものではない。 Further, the number of pipes included in the heat absorbing plate is appropriately set as necessary, and is not limited to the above-described form.
