Description

本発明は、家庭用の熱交換型換気扇やビルなどの熱交換型換気装置、またはその他の空気調和装置に使用する積層構造の熱交換素子に関する。   The present invention relates to a heat exchange element having a laminated structure for use in a heat exchange type ventilator such as a household heat exchange type ventilator or a building, or other air conditioner.

従来、この種の熱交換素子は、コルゲート加工を応用したのもが知られている（例えば、特許文献１参照）。   Conventionally, this type of heat exchange element is known to apply corrugating (see, for example, Patent Document 1).

以下、その熱交換素子について、図１５及び図１６を参照しながら説明する。   Hereinafter, the heat exchange element will be described with reference to FIGS. 15 and 16.

図１５に示すように、熱交換器１０１は、一定の間隔を有して対向した一対のプレート１０２と、プレート１０２間の間隙に複数の平行流路１０３を形成するための波形断面形状を有する板状のフィン１０４と、プレート１０２の一段おきに導入された一次気流Ｍと二次気流Ｎをそれぞれガイドするスペーサー１０５から形成され、フィン１０４によって形成された平行流路１０３の下流側に空間部１０６を有する。プレート１０２とフィン１０４及びプレート１０２とスペーサー１０５は接着剤により接合される。   As shown in FIG. 15, the heat exchanger 101 has a pair of plates 102 opposed to each other with a constant interval, and a corrugated cross-sectional shape for forming a plurality of parallel flow paths 103 in the gaps between the plates 102. A plate-like fin 104 and a spacer 105 for guiding the primary air flow M and the secondary air flow N introduced at every other stage of the plate 102 are formed on the downstream side of the parallel flow path 103 formed by the fins 104. 106. The plate 102 and the fin 104, and the plate 102 and the spacer 105 are joined by an adhesive.

また、一次気流Ｍと二次気流Ｎの流入口はそれぞれ対向する面に配置され、一次気流Ｍと二次気流Ｎの流出口は一次気流Ｍと二次気流Ｎの流入口が配置された面と垂直となる面に配置され、一次気流Ｍと二次気流Ｎの流出口が配置された面と対向となる面は閉塞されている。   In addition, the inlets of the primary airflow M and the secondary airflow N are arranged on opposite surfaces, and the outlets of the primary airflow M and the secondary airflow N are surfaces on which the inlets of the primary airflow M and the secondary airflow N are arranged. The surface opposite to the surface on which the outlets of the primary airflow M and the secondary airflow N are disposed is closed.

なお、図１６に示すように、フィン１０４を一方から流出口が配置された面側へと連続的にピッチＰが小さくなるように形成し平行流路１０３の流路断面積を変化させることによって熱交換効率の向上を図ったものである。
特開昭６０−２３８６８９号公報 In addition, as shown in FIG. 16, the fin 104 is formed so that the pitch P is continuously reduced from one side to the surface side where the outflow port is arranged, and the channel cross-sectional area of the parallel channel 103 is changed. This is intended to improve heat exchange efficiency.
JP 60-238689 A

このような従来の熱交換器１０１では、プレート１０２間の間隔を小さくして限られた積層高さの中で伝熱面積を増加することで熱交換効率を向上する場合にプレート１０２とフィン１０４の接合部を平行流路１０３の構造維持のために増やさなければならないため接合部によって伝熱板の有効面積を減少させ、さらにプレート１０２とフィン１０４を接合させるために用いられる接着剤が接合部分からはみ出すことによってプレート１０２の有効面積を大幅に減少させるため、熱交換効率が低下するという課題があり、熱交換効率を向上するということが要求されている。   In such a conventional heat exchanger 101, the plate 102 and the fin 104 are used when the heat transfer efficiency is improved by reducing the distance between the plates 102 and increasing the heat transfer area in a limited stacking height. Since the joint portion of the heat transfer plate has to be increased in order to maintain the structure of the parallel flow path 103, the effective area of the heat transfer plate is reduced by the joint portion, and the adhesive used for joining the plate 102 and the fin 104 is joined to the joint portion. Since the effective area of the plate 102 is greatly reduced by protruding from the surface, there is a problem that the heat exchange efficiency is lowered, and it is required to improve the heat exchange efficiency.

また、プレート１０２及びプレート１０２が紙で形成されている場合、実際に製造を行うにあたってピッチＰが不揃いであるフィン１０４とスペーサー１０５の厚みを精度よく揃えるのは難しく、接着する際に厚みが大きいフィン１０４は潰され、厚みが小さいフィン１０４はプレート１０２とうまく接合できなくなり、設計したピッチＰを実現することができないとともに厚み方向の精度が低いためにプレート１０２の変形や、一段ごとの積層高さが異なることにより熱交換素子内に偏流を生じるため熱交換効率が低下するという課題があり、熱交換効率を向上するということが要求されている。   In addition, when the plate 102 and the plate 102 are formed of paper, it is difficult to accurately align the thicknesses of the fins 104 and the spacers 105 whose pitch P is not uniform in actual manufacturing, and the thickness is large when bonding. The fins 104 are crushed, and the fins 104 having a small thickness cannot be joined to the plate 102 well, so that the designed pitch P cannot be realized and the accuracy in the thickness direction is low. Due to the difference in size, there is a problem that the heat exchange efficiency is lowered because of the occurrence of drift in the heat exchange element, and it is required to improve the heat exchange efficiency.

また、フープ材の伝熱紙を使用する場合、伝熱紙は湿度等によりフープ方向に対して垂直方向に寸法が変動しやすいことが知られており、熱交換素子を製造した後の伝熱紙の収縮による接着部分の剥がれによる一次気流Ｎと二次気流Ｍ相互間の混流の増加や、紙の膨張によりプレート１０２が変形し熱交換素子内に偏流を生じるため熱交換効率が低下するという課題があり、伝熱紙の変形の影響を受けずに安定した熱交換効率を維持できることが要求されている。   In addition, when using a heat transfer paper made of a hoop material, it is known that the heat transfer paper tends to vary in dimensions in the direction perpendicular to the hoop direction due to humidity, etc., and heat transfer after the heat exchange element is manufactured. The heat exchange efficiency is reduced because the plate 102 is deformed due to the increase in the mixed flow between the primary air flow N and the secondary air flow M due to the peeling of the adhesive portion due to the shrinkage of the paper and the expansion of the paper, causing a drift in the heat exchange element. There is a problem, and it is required to maintain stable heat exchange efficiency without being affected by deformation of heat transfer paper.

このような従来の熱交換素子では、湿度等による伝熱紙の変形により、熱交換効率性能が不安定となってしてしまうという課題がある。   Such a conventional heat exchange element has a problem that the heat exchange efficiency performance becomes unstable due to deformation of the heat transfer paper due to humidity or the like.

本発明は、このような従来の課題を解決するものであり、高い熱交換効率性能を安定して得ることができる熱交換素子を提供することを目的とする。   This invention solves such a conventional subject, and it aims at providing the heat exchange element which can obtain a high heat exchange efficiency performance stably.

このように本発明の実施の形態７の熱交換素子によれば、分割リブ１２ｃと伝熱紙２がインサート成型により接着され、また分割リブ１２ｃと伝熱紙２の接着面積が増加するため伝熱紙２の変形を矯正する。さらに製造時の接合強度のばらつきをなくすことができ、熱交換効率の変動をなくすことができることとなる。   As described above, according to the heat exchange element of Embodiment 7 of the present invention, the divided ribs 12c and the heat transfer paper 2 are bonded by insert molding, and the bonding area between the divided ribs 12c and the heat transfer paper 2 is increased. The deformation of the hot paper 2 is corrected. Further, it is possible to eliminate variations in bonding strength during manufacturing, and to eliminate fluctuations in heat exchange efficiency.

（実施の形態８）
図１２に示すように、遮蔽リブ９と分割リブ１２ｃを熱可塑性樹脂にて一体で形成し、さらに伝熱紙２を遮蔽リブ９の高さ方向の中央部に配置するようにインサート成型することにより遮蔽リブ９と分割リブ１２ｃを伝熱紙の両面に形成する際、遮蔽リブ９に、凹凸形状１５を設けた構成とする。 (Embodiment 8)
As shown in FIG. 12, the shielding rib 9 and the dividing rib 12 c are integrally formed of a thermoplastic resin, and the heat transfer paper 2 is insert-molded so as to be arranged at the center of the shielding rib 9 in the height direction. Thus, when the shielding rib 9 and the dividing rib 12c are formed on both sides of the heat transfer paper, the shielding rib 9 is provided with the uneven shape 15.

上記構成により、分割リブ１２ｃと伝熱紙２がインサート成型により接着され、また分割リブ１２ｃと伝熱紙２の接着面積が増加するため伝熱紙２の変形を矯正する。さらに凹凸形状１５が勘合し積層時に遮蔽リブ９間を空気が流れようとする際の圧力損失を増加させる。   With the above configuration, the split rib 12c and the heat transfer paper 2 are bonded by insert molding, and the bonding area between the split rib 12c and the heat transfer paper 2 is increased, so that the deformation of the heat transfer paper 2 is corrected. Furthermore, the uneven shape 15 is fitted to increase the pressure loss when air is about to flow between the shielding ribs 9 during lamination.

このように本発明の実施の形態８の熱交換素子によれば、分割リブ１２ｃと伝熱紙２がインサート成型により接着され、また分割リブ１２ｃと伝熱紙２の接着面積が増加するため伝熱紙２の変形を矯正する。さらに漏れ風量を低減することができ、熱交換効率の変動をなくすことができることとなる。   As described above, according to the heat exchange element of the eighth embodiment of the present invention, the split rib 12c and the heat transfer paper 2 are bonded by insert molding, and the bonding area between the split rib 12c and the heat transfer paper 2 is increased. The deformation of the hot paper 2 is corrected. Furthermore, the amount of leaked air can be reduced, and fluctuations in heat exchange efficiency can be eliminated.

（実施の形態９）
図１３に示すように、遮蔽リブ９を熱可塑性樹脂にて一体で形成し、さらに伝熱紙２を遮蔽リブ９の高さ方向の中央部に配置するようにインサート成型することにより遮蔽リブ９を伝熱紙２の両面に形成し、伝熱紙表裏の片面に、伝熱紙２の所定間隔の高さの複数本の分割リブ１２ｄを設けた構成とする。 (Embodiment 9)
As shown in FIG. 13, the shielding rib 9 is integrally formed of a thermoplastic resin, and the heat transfer paper 2 is insert-molded so as to be disposed at the center of the shielding rib 9 in the height direction. Is formed on both surfaces of the heat transfer paper 2, and a plurality of divided ribs 12d having a predetermined interval height of the heat transfer paper 2 are provided on one side of the heat transfer paper.

上記構成により、分割リブ１２ｄの断面積が増加する。   With the above configuration, the sectional area of the dividing rib 12d increases.

このように本発明の実施の形態９の熱交換素子によれば、製造過程において熱可塑性樹脂が流れやすくなり、分割リブ１２ｄの高さをより低くできるため伝熱紙２の間隔を小さくでき、限られた積層寸法の条件下で伝熱紙２の数量を増加させることができるので熱交換効率性能が向上できることとなる。   Thus, according to the heat exchange element of the ninth embodiment of the present invention, the thermoplastic resin can easily flow in the manufacturing process, and the height of the dividing rib 12d can be further reduced, so that the interval between the heat transfer papers 2 can be reduced. Since the quantity of the heat transfer paper 2 can be increased under the condition of the limited stacking dimensions, the heat exchange efficiency performance can be improved.

（実施の形態１０）
図１４に示すように、遮蔽リブ９を熱可塑性樹脂にて一体で形成し、さらに伝熱紙２を遮蔽リブ９の高さ方向の中央部に配置するようにインサート成型することにより遮蔽リブ９を伝熱紙２の両面に形成し、伝熱紙表裏の片面に、伝熱紙の所定間隔の高さの複数本の分割リブ１２ｄを設け、分割リブと分割リブの間に複数本の補強リブ１６を設けた構成とする。 (Embodiment 10)
As shown in FIG. 14, the shielding rib 9 is integrally formed of a thermoplastic resin, and the heat transfer paper 2 is insert-molded so as to be disposed at the center of the shielding rib 9 in the height direction. Is formed on both sides of the heat transfer paper 2, and a plurality of divided ribs 12d having a predetermined interval height of the heat transfer paper are provided on one side of the heat transfer paper, and a plurality of reinforcements are provided between the divided ribs. The rib 16 is provided.

上記構成により、分割リブ１２ｄと伝熱紙２の接着面積に補強リブ１６と伝熱紙２の接着面積が追加される。   With the above configuration, the bonding area between the reinforcing ribs 16 and the heat transfer paper 2 is added to the bonding area between the divided ribs 12 d and the heat transfer paper 2.

このように本発明の実施の形態１０の熱交換素子によれば、熱可塑性樹脂が流れやすくなることで分割リブ１２ｄの高さを低くできるため伝熱紙の間隔を小さくでき、限られた積層寸法の条件下で伝熱紙の数量を増加させることができるので熱交換効率性能が向上し、さらに、伝熱紙２の変形を分割リブ１２ｄ及び補強リブ１６により矯正できるので湿度等の影響により伝熱紙２の変形が生じる場合においても熱交換効率性能の変動をなくすことができることとなる。   Thus, according to the heat exchange element of the tenth embodiment of the present invention, the height of the dividing rib 12d can be reduced by facilitating the flow of the thermoplastic resin, so the interval between the heat transfer papers can be reduced, and the limited lamination Since the number of heat transfer papers can be increased under dimensional conditions, the heat exchange efficiency performance is improved. Further, the deformation of the heat transfer paper 2 can be corrected by the dividing ribs 12d and the reinforcing ribs 16, so that it is affected by the influence of humidity and the like. Even when the heat transfer paper 2 is deformed, fluctuations in the heat exchange efficiency performance can be eliminated.
