Description

本発明は、コンデンサ、エバポレータ、ヒータコア、ラジエータ等の熱交換器のヘッダタンクに関する。   The present invention relates to a header tank of a heat exchanger such as a condenser, an evaporator, a heater core, or a radiator.

一般に積層型熱交換器は、図２に示すように複数のチューブ１とフィン２とが交互に積層され、これらの積層されたチューブ１の一端側に入口側ヘッダタンク３が、他端側に出口側ヘッダタンク（図示せず）が連通接続されている。入口側ヘッダタンク３の適所には熱交換流体を導入する流入口３ａが、他方の出口側ヘッダタンクの適所には熱交換流体を排出する流出口が設けられ、必要に応じてこれら流出入口間で熱交換流体が複数回蛇行して流れるように、両ヘッダタンク内の所要個所にヘッダタンク内を区切る仕切板（図示せず）が配設されている。また、両ヘッダタンクに設けられた流出入口には、一般にコネクタを介して熱交換流体を導入もしくは排出する配管（図示せず）が取り付けられている。   In general, a laminated heat exchanger has a plurality of tubes 1 and fins 2 alternately laminated as shown in FIG. 2, and an inlet side header tank 3 is provided at one end side of the laminated tubes 1 and the other end side thereof. An outlet header tank (not shown) is connected in communication. An inlet 3a for introducing the heat exchange fluid is provided at a proper position of the inlet side header tank 3, and an outlet for discharging the heat exchange fluid is provided at a proper position of the other outlet side header tank. In order to allow the heat exchange fluid to meander and flow multiple times, a partition plate (not shown) that divides the header tank is disposed at a required location in both header tanks. Also, piping (not shown) for introducing or discharging a heat exchange fluid is generally attached to the outflow inlets provided in both header tanks via a connector.

このような積層型熱交換器のヘッダタンク３は、耐圧強度を必要とすること、及びフィンとチューブとよりなるコア部とヘッダタンクとを組み付けした後にろう付けするという製造上の理由から、一般に金属材料、特にアルミニウム材料で作られていた。しかしながら、金属材料から作られるヘッダタンクは、材料コスト及び製造コストが高くなるという問題があった。
そのために金属材料に代えて樹脂材料によりヘッダタンクを作ることも考えられたが、その場合は、ヘッダタンクの耐圧強度が不足するという問題がある。これは、内部に案内板を設けていないヘッダタンクにおいて、特に著しかった。 The header tank 3 of such a stacked heat exchanger generally requires pressure resistance strength and is generally manufactured for the reason of brazing after assembling the core portion and the header tank made up of fins and tubes. Made of metal material, especially aluminum material. However, the header tank made of a metal material has a problem that the material cost and the manufacturing cost increase.
For this reason, it has been considered that the header tank is made of a resin material instead of the metal material, but in this case, there is a problem that the pressure resistance of the header tank is insufficient. This was particularly remarkable in a header tank that did not have a guide plate inside.

本発明は、上記問題に鑑みてなされたもので、その目的は、耐圧強度が十分に確保でき、かつ材料コスト及び製造コストを削減することができる熱交換器のヘッダタンクを提供することである。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a header tank of a heat exchanger that can sufficiently ensure pressure resistance and can reduce material costs and manufacturing costs. .

本発明は、前記課題を解決するための手段として、特許請求の範囲の各請求項に記載の熱交換器のヘッダタンクを提供する。
請求項１に記載の熱交換器のヘッダタンクは、ヘッダタンクが樹脂材料から形成されていて、ヘッダタンクの長手方向の一端側に偏って流入口が設けられていると共に、その内部に流入口が設けられた側から対向する側に向かって延びる、整流板を兼用する補強リブを設けるようにしたものであり、これにより、ヘッダタンクの耐圧強度を上げることができ、樹脂製のヘッダタンクを可能にしたものである。また、ヘッダタンクの材料コスト及び製造コストを削減できる。更に、補強リブに整流板を兼用させているので、ヘッダタンク内の熱交換流体を各チューブに出来るだけ均等に分配することができ、熱交換効率を向上することができる。 The present invention provides a header tank of a heat exchanger as set forth in each claim as a means for solving the above-mentioned problems.
Header tank of a heat exchanger according to claim 1, the header tank is formed from a resin material, together with the inlet biased to one longitudinal end of the header tank is provided, the inlet therein Is provided with reinforcing ribs that also serve as a current plate extending from the side provided to the opposite side , whereby the pressure resistance of the header tank can be increased, and the resin header tank It is possible. Moreover, the material cost and manufacturing cost of the header tank can be reduced. Furthermore, since the reinforcing ribs are also used as the current plate, the heat exchange fluid in the header tank can be distributed as evenly as possible to each tube, and the heat exchange efficiency can be improved.

また、請求項１の該ヘッダタンクは、補強リブが湾曲していることを規定したものであり、請求項１の該ヘッダタンクは、補強リブが流入口の中央から延びていることを規定したものである。
また、請求項１の該ヘッダタンクは、流入口がヘッダタンクの長手方向の側壁に接続していることを規定したものである。
また、請求項１の該ヘッダタンクは、補強リブをヘッダタンクと一体に形成するようにしたものであり、これにより、ヘッダタンクの製造効率を改善でき、製造コストを下げることができる。 Further, the header tank according to claim 1 is obtained by defining that the reinforcing rib is curved, the header tank of claim 1 was defined that the reinforcing ribs extend from a central inlet Is.
The header tank according to claim 1 defines that the inlet is connected to the longitudinal side wall of the header tank.
Further, the header tank according to claim 1 is configured such that the reinforcing rib is formed integrally with the header tank, whereby the manufacturing efficiency of the header tank can be improved and the manufacturing cost can be reduced.

以下、図面に基づいて本発明の実施の形態の熱交換器のヘッダタンクについて説明する。図１は、本発明の熱交換器のヘッダタンクの正面図及び平面図を示している。熱交換器は、熱交換流体が流通する複数の扁平状のチューブ１と波状のフィン（コルゲートフィン）２とが交互に積層され、これらの積層されたチューブ２の両端側にはヘッダプレート４が接続していて、このヘッダプレート４を覆うようにしてヘッダタンク３（図面においては片側のヘッダタンクのみが示されている）が設けられている。一方のヘッダタンク３には、外部から熱交換流体を導入する流入口３ａが設けられ、他方のヘッダタンク（図示せず）には、熱交換が終了した熱交換流体を外部に排出する流出口（図示せず）が設けられている。従ってヘッダタンク３は、複数本のチューブ１内を流通する熱交換流体を分配集合させている。このようにして、チューブ１内を通る熱交換流体とチューブ１外のフィン２を通る空気との間で熱交換が行われる。なお、チューブ１とフィン２とから構成されるコア部の、チューブ１の長手方向に直交する方向の両端部には、サイドプレート６が設けられていて、コア部を補強している。   Hereinafter, a header tank of a heat exchanger according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1: has shown the front view and top view of the header tank of the heat exchanger of this invention. In the heat exchanger, a plurality of flat tubes 1 and corrugated fins (corrugated fins) 2 through which a heat exchange fluid flows are alternately stacked, and header plates 4 are provided at both ends of the stacked tubes 2. A header tank 3 (only one header tank is shown in the drawing) is provided so as to cover the header plate 4. One header tank 3 is provided with an inlet 3a for introducing a heat exchange fluid from the outside, and the other header tank (not shown) is an outlet for discharging the heat exchange fluid after heat exchange to the outside. (Not shown) is provided. Therefore, the header tank 3 distributes and collects the heat exchange fluid flowing through the plurality of tubes 1. In this way, heat exchange is performed between the heat exchange fluid passing through the tube 1 and the air passing through the fins 2 outside the tube 1. In addition, the side plate 6 is provided in the both ends of the core part comprised from the tube 1 and the fin 2 in the direction orthogonal to the longitudinal direction of the tube 1, and the core part is reinforced.

次に本発明の特徴であるヘッダタンク３について説明する。本発明においては、ヘッダタンク３が樹脂材料の成形加工によって形成される。この樹脂材料には、ガラス繊維又はカーボン繊維等の補強繊維を添加してもよい。この樹脂製のヘッダタンク３は、従来の金属製のヘッダタンクに比べて、耐圧強度で劣る恐れがある。そのため、本発明では、この樹脂製のヘッダタンク３の内部に耐圧強度の強化を図るために補強リブ５を設けている。樹脂材料としては、公知の熱可塑性の樹脂であれば使用可能である。   Next, the header tank 3 which is a feature of the present invention will be described. In the present invention, the header tank 3 is formed by molding a resin material. A reinforcing fiber such as glass fiber or carbon fiber may be added to the resin material. The resin header tank 3 may be inferior in pressure resistance compared to a conventional metal header tank. Therefore, in the present invention, the reinforcing rib 5 is provided in the resin header tank 3 in order to enhance the pressure strength. As the resin material, any known thermoplastic resin can be used.

この補強リブ５の形状は、ヘッダタンク３の耐圧強度を高めることができるならどのような形状でもよいが、熱交換流体が各チューブ１に万遍無く行き渡るように整流作用をもつような形状が好ましい。図１に示される補強リブ５は、ヘッダタンク３の流入口３ａから対向する側面に向かって湾曲板状に設けられていて、流入口３ａから導入される熱交換流体が左右に分配されて、ヘッダタンク３内部に行き渡るようになっている。   The shape of the reinforcing rib 5 may be any shape as long as the pressure strength of the header tank 3 can be increased. However, the shape of the reinforcing rib 5 has a rectifying action so that the heat exchange fluid can be distributed evenly to each tube 1. preferable. The reinforcing rib 5 shown in FIG. 1 is provided in a curved plate shape from the inlet 3a of the header tank 3 toward the opposite side surface, and the heat exchange fluid introduced from the inlet 3a is distributed to the left and right, It reaches the inside of the header tank 3.

図１においては、補強リブ５は１つしか設けられていないが、複数設けることも可能である。また、図１では、熱交換流体が導入される側のヘッダタンク３にしか補強リブ５が設けられていないが、熱交換流体が排出される側のヘッダタンク３にも、当然補強リブ５が設けられるものである。この場合、補強リブ５の形状を、各チューブ１からの熱交換流体が流出口に向かって集められるような形状にすることが好ましい。   In FIG. 1, only one reinforcing rib 5 is provided, but a plurality of reinforcing ribs 5 may be provided. In FIG. 1, the reinforcing rib 5 is provided only on the header tank 3 on the side where the heat exchange fluid is introduced, but the reinforcing rib 5 is naturally provided on the header tank 3 on the side where the heat exchange fluid is discharged. It is provided. In this case, the shape of the reinforcing rib 5 is preferably such that the heat exchange fluid from each tube 1 is collected toward the outlet.

この補強リブ５は、ヘッダタンク３と別体で形成し、後にヘッダタンク３の内壁に固着するようにしてもよいが、好ましくは、ヘッダタンク３と一体に成形加工により形成される。こうすることにより、作業手順が減り、補強リブ付きヘッダタンクを安価に製造できる。   The reinforcing rib 5 may be formed separately from the header tank 3 and may be fixed to the inner wall of the header tank 3 later, but is preferably formed integrally with the header tank 3 by molding. By doing so, the work procedure is reduced, and the header tank with the reinforcing rib can be manufactured at low cost.

以上説明したように、本発明では、ヘッダタンクに補強リブを設けることによって、耐圧強度を十分に確保できるヘッダタンクを樹脂材料で形成することができ、材料及び製造コストの削減を図ることができる。また、補強リブに熱交換流体を整流させる整流板としての機能をもたせることによって、熱交換流体を各チューブに略平等に分配させることができ、熱交換効率を改善することもできる。   As described above, in the present invention, by providing the header tank with the reinforcing rib, the header tank that can sufficiently secure the pressure strength can be formed of the resin material, and the material and the manufacturing cost can be reduced. . Further, by providing the reinforcing rib with a function as a rectifying plate for rectifying the heat exchange fluid, the heat exchange fluid can be distributed substantially evenly to the tubes, and the heat exchange efficiency can be improved.

本発明の実施の形態の熱交換器のヘッダタンクの正面図と平面図である。It is the front view and top view of the header tank of the heat exchanger of embodiment of this invention. 従来の熱交換器のヘッダタンクである。It is a header tank of the conventional heat exchanger.
