。A feature of the present invention is that the rectangular passages are integrally molded from a crystalline resin related to thermoplastic resin so that a plurality of open rectangular passages are adjacent to each other and orthogonal so that the fluids flowing through the respective passages can cross at right angles. In an AC heat exchanger, the short side dimensions of the rectangular passages that are orthogonal to each other are approximately the same, and the length ratio of the rectangular passages in the flow direction is 1:1.
It is found in a heat exchanger formed to have a ratio between 1:3 and 1:3.

面積を確保できるようにしたものである。More specifically, in order to enable integral molding, a plurality of hollow rectangular passages are arranged perpendicularly to each other, and the length ratio of each rectangular passage in the fluid flow direction is set to 1:1 to 1:3. By doing so, it is possible to arrange rectangular tubes related to rectangular passages at small intervals even when integrally molded, and by providing a flange portion at one entrance and exit of the rectangular passages that are orthogonal to each other, a convex portion provided on the flange portion is provided. In this section, a plurality of integrally molded products are joined and integrated to maintain airtightness and secure a heat transfer area with the required heat exchange ability.
次に、本発明に係る実施例を、各図を参照して説明する
。Next, embodiments according to the present invention will be described with reference to the respective figures.
まず、第１図は、本発明の一実施例に係る熱交換器の斜
視図である。First, FIG. 1 is a perspective view of a heat exchanger according to an embodiment of the present invention.
図で、１は、フランジ部に係るフランジＡ、 ２は、同
様にフランジＢ、３は矩形通路に係る矩形管、４は、同
様に矩形通路に係る矩形開口通路、５は凸部であり、６
は熱交換器を示すものである。In the figure, 1 is a flange A related to a flange portion, 2 is a flange B similarly, 3 is a rectangular tube related to a rectangular passage, 4 is a rectangular opening passage similarly related to a rectangular passage, and 5 is a convex portion. 6
indicates a heat exchanger.
なお、上記のフランジ部は、流路に係る両矩形通路にお
ける出入口のいずれにも設けることがあるもので、図示
のものは、その少なくとも一方の矩形通路側に設けるよ
うにしたものである。Note that the above-mentioned flange portion may be provided at either of the entrances and exits of both rectangular passages related to the flow path, and the one shown is provided on at least one of the rectangular passages.
すなわち、熱交換器６の本体は、ポリプロピレンなどの
熱可塑性樹脂に係る結晶性樹脂で一体成形されるもので
あり、フランジＡｔ、フランジＢ２を貫通する複数個の
矩形管３は、一方の流体の矩形通路となっており、この
矩形管３の外表面は、それぞれ他方の流体の矩形通路で
ある矩形開口通路４となっているものであって、矩形管
３の矩形通路は、図の左右方向の通路、また矩形開口通
路４の矩形通路は、図の上下方向の通路、を形成し、互
いに隣接して直交する通路となっているものである。That is, the main body of the heat exchanger 6 is integrally molded from a crystalline resin related to thermoplastic resin such as polypropylene, and the plurality of rectangular pipes 3 passing through the flange At and flange B2 are connected to one fluid. The outer surface of each rectangular tube 3 is a rectangular opening passage 4, which is a rectangular passage for the other fluid. The passage 4 and the rectangular passage of the rectangular opening passage 4 form a passage in the vertical direction in the figure, and are adjacent to each other and orthogonal to each other.
しかして、矩形管３の外表面が、二つの流体の伝熱面で
あり、同じ体積内であれば、この矩形管３０本数が多い
程、伝熱面積が増大するわけであるが、熱交換器６本体
をポリプロピレンなどの結晶性樹脂により一体成形する
には、その射出成形時の圧力により、矩形管３．矩矩形
開通路４を形造する金型が変形するので、それ程、図示
のそれぞれの矩形通路の短辺側寸法ａ、ｂを小さくする
ことはできず、その本数には限界がある。Therefore, the outer surface of the rectangular tube 3 is the heat transfer surface for the two fluids, and if the volume is the same, the more rectangular tubes 30, the greater the heat transfer area. In order to integrally mold the main body of the vessel 6 from a crystalline resin such as polypropylene, the pressure during injection molding is used to form the rectangular tube 3. Since the mold for forming the rectangular open passage 4 is deformed, the short side dimensions a and b of each of the rectangular passages shown in the figure cannot be reduced to that extent, and there is a limit to the number of rectangular passages.
また、図示の矩形管３の流れ方向の長さり、矩形開口通
路４の流れ方向の長さＭも、同上金型の強度に関係する
ものであり、その成形時の金型の変形９強度を考慮する
と、前記の短辺側寸法ａ。In addition, the length of the illustrated rectangular tube 3 in the flow direction and the length M of the rectangular opening passageway 4 in the flow direction are also related to the strength of the mold, and the deformation strength of the mold during molding is determined by the strength of the mold. Considering the short side dimension a.
ｂを、はぼ同じにした場合、図示の長さＭとＬとの比が
１：１ないし１：３が、その選択範囲である。When b are made almost the same, the selection range is a ratio of 1:1 to 1:3 between lengths M and L shown in the figure.
これらを考え、たとえば、同じ体積内で伝熱面積を最大
にするには、短辺側寸法ａ、ｂをζはぼ同じにし、まだ
、長さＬとＭとを、はぼ同じになるように形成すればよ
く、この場合、矩形管３゜矩形開口通路４を作る、それ
ぞれの金型の強度がほぼ同一となるものであり、たとえ
ば、ａ−ｂ−４、５ａｘ程度、Ｌ＝Ｍ＝８０Ｗ程度が例
示寸法である。Considering these, for example, in order to maximize the heat transfer area within the same volume, the short side dimensions a and b should be approximately the same ζ, and the lengths L and M should be approximately the same. In this case, the strength of each mold for making the rectangular tube 3° and the rectangular opening passage 4 is almost the same, for example, about a-b-4, 5ax, L=M= An exemplary dimension is about 80W.
このようにすれば、二つの流体の流量が、はぼ等しいと
きに、圧力損失を同じにすることができるものである。In this way, when the flow rates of the two fluids are approximately equal, the pressure loss can be made the same.
これらを総合して、図示の本実施例においては、短辺側
寸法ａ、ｂを、はぼ同じとし、上記の長さＭとＬとの比
を、上述の比の範囲内においての、それぞれの長さとし
たものであって、たとえばＭ。Taking all of this into consideration, in the illustrated embodiment, the short side dimensions a and b are approximately the same, and the ratios of the above lengths M and L are set within the range of the above ratios. For example, M.
Ｉ７の長さ自体は５ｏ祁がら２’ Ｏ０ｔｒａｎ （３
倍にしたときの上限値）の間が例示寸法であり、これに
よって、金型の強度を考慮したうぇで９生産性を確保で
きるようにしたものである。The length of I7 itself is 5o to 2' O0tran (3
The example dimensions are between the upper limit value when doubled, and this makes it possible to ensure productivity by taking into account the strength of the mold.
そして、図示のような、長さＬとＭとの場合を含め、一

ける流入開口面積を多くすることができるので、結局、
その上下、および紙面の左右方向の流路における流速間
においては、はぼ同じ流速比とすることができ、圧力損
失を同一とすることができるものである。In general, when one side is cooling air and there is a difference in flow rate between the two, including the case of the lengths L and M as shown in the figure, as shown in the perspective view of FIG. 2, By stacking a plurality of them, that is, by configuring the one with a higher flow rate to pass in the vertical direction of the page, the area of the inflow opening in the vertical direction can be increased.
The flow velocities in the upper and lower channels and in the left and right directions of the paper can have almost the same flow velocity ratio, and the pressure loss can be made the same.

熱面積を得ることができるものである。In this example, in connection with laminating a plurality of layers,
The flange At and the flange B2 are integrally formed with a convex portion 5 having the same shape. When stacking multiple pieces, the convex portion 5 is formed by joining means such as ultrasonic waves or hot plate welding as shown in FIG. The joint parts 7 that join the parts 5 can be integrated in an airtight and watertight manner, thereby making it possible to obtain the required heat transfer area.

るものである。In addition to the above, in this embodiment, as mentioned above, resins such as polypropylene and polyethylene, which are thermoplastic and crystalline resins, are used as the material for integrally molding the heat exchanger 6. In heat exchange between a gas and a gaff body, especially when one of the fluids is at high temperature and high humidity and is cooled and dehumidified, moisture is precipitated and separated on the heat exchange surface. Because its adsorption power is weak, it can be discharged quickly, and its heat exchange performance can be improved.

る。In addition, when the required heat transfer area is achieved by laminating multiple layers, the convex parts on the flange can be joined with a welding ring, resulting in high airtight reliability and productivity. There will be some gaps between the rectangular tubes of the container, so
An increase in heat exchange efficiency due to the generation of turbulent flow can also be expected.

In order to obtain the necessary heat exchange capacity, it is sufficient to stack multiple pieces together, which makes it easy to adapt to various heat exchange capacities, and also improves airtight reliability and productivity. It can be said that the invention can provide highly functional properties and can be expected to have excellent practical effects.
