従来、自動車の室内空調機器を構成する熱交換器として図２に示すものが知ら れている。この熱交換器１は上下に延び対向して配置された円筒状のヘッダ−２ ，３と、この各ヘッダ−２，３に接続穴４を介して両端が連通し上下に複数段に 架設された偏平の熱交換チュ−ブ５とを備えており、この各熱交換チュ−ブ５間 には熱交換フィン６が介装されている。 Conventionally, the heat exchanger shown in Figure 2 is known as a heat exchanger that constitutes the indoor air conditioning equipment of automobiles. It is. This heat exchanger 1 has a cylindrical header 2 which extends vertically and is disposed facing each other. , 3, and both ends are connected to each header 2, 3 through the connection hole 4 in multiple stages above and below. It is equipped with an installed flat heat exchange tube 5, and the distance between each heat exchange tube 5 is Heat exchange fins 6 are interposed in the fins.
【０００３】 この一方のヘッダ−２の上方には冷媒の入口パイプ７ａを、下方には出口パイ プ７ｂをそれぞれ設けるとともに、ヘッダ−２の略中央の内部にはヘッダ−２を 上下に仕切る仕切板８が配設されている。0003 A refrigerant inlet pipe 7a is provided above one of the headers 2, and an outlet pipe is provided below. A header 2 is provided inside approximately the center of the header 2. A partition plate 8 is provided to partition the space into upper and lower parts.
【０００４】 この仕切板８とヘッダ−２との連結構造は、実開昭６３−４９１９３号公報に おいて開示されており、図３及び図４の(a) に示すように、このヘッダ−２の周 壁２ａには一個の挿入穴９を設けている。他方、仕切板８はヘッダ−２の内周面 に適合するよう形成された小径部８ａと、ヘッダ−２の外周面に適合するよう形 成された大径部８ｂとを有しており、この仕切板８の小径部８ａを挿入穴９から ヘッダ−２内に挿入することにより、この仕切板８でヘッダ−２が上下に仕切ら れる。0004 The connection structure between the partition plate 8 and the header 2 is described in Japanese Utility Model Application No. 63-49193. As shown in FIGS. 3 and 4(a), the periphery of this header 2 is One insertion hole 9 is provided in the wall 2a. On the other hand, the partition plate 8 is connected to the inner peripheral surface of the header 2. The small diameter portion 8a is formed to fit the header 2, and the small diameter portion 8a is formed to fit the outer peripheral surface of the header 2.

しかしながら、前記従来の熱交換器では、仕切板８の小径部８ａ及び大径部８ ｂをヘッダ−２の内外周面にそれぞれ適合するように形成したとしても、仕切板 ８の組み付け時に図４の(b) に示すような不具合が生ずることがある。すなわち 、図４の(b) に示すように、小径部８ａと大径部８ｂとの連結切り欠き部分８ｃ が小径部８ａ側に形成されているときは、この小径部８ａとヘッダ−２との間に 隙間Ａが形成され、熱交換媒体がこの隙間Ａから漏れることとなる。 However, in the conventional heat exchanger, the small diameter portion 8a and the large diameter portion 8 of the partition plate 8 Even if b is formed to fit the inner and outer peripheral surfaces of header 2, the partition plate When assembling 8, a problem as shown in FIG. 4(b) may occur. i.e. , as shown in FIG. 4(b), a connecting notch portion 8c between the small diameter portion 8a and the large diameter portion 8b. is formed on the small diameter portion 8a side, between this small diameter portion 8a and the header 2. A gap A is formed through which the heat exchange medium will leak.
【０００６】 このようなときは、この不良部品である仕切板８を適性な部品と交換すればよ いが、この隙間Ａがヘッダ−２の内部でヘッダ−２の外側から目視できないため 、この不良部品をそのまま使用する場合が多々あり、熱交換器１の性能の低下を 招くという問題点を有していた。[0006] In such a case, it is best to replace the defective part, the partition plate 8, with a suitable part. However, this gap A is inside the header 2 and cannot be seen from the outside of the header 2. , this defective part is often used as is, which may cause a decline in the performance of heat exchanger 1. There was a problem with inviting people.
【０００７】 このような従来の熱交換器の問題点を解決するため、特開平２−１８３７９６ 号公報において、図５の(a) に示すものが開示されている。この熱交換器におい ては、ヘッダ−２に互いに対向する挿入穴１０ａ，１０ｂを２個設け、一方の挿 入穴１０ａは他方の挿入穴１０ｂよりその開口長さを短く形成している。また、 仕切板１１はその挿入方向の先端を挿入穴１０ａに適合するよう形成し、仕切板 １１の後端側は挿入穴１０ｂに適合するよう形成している。[0007] In order to solve the problems of conventional heat exchangers, In the publication, the one shown in FIG. 5(a) is disclosed. This heat exchanger smell In this case, two insertion holes 10a and 10b facing each other are provided in the header 2, and one of the insertion holes is The opening length of the insertion hole 10a is shorter than that of the other insertion hole 10b. Also, The partition plate 11 has its tip in the insertion direction formed so as to fit into the insertion hole 10a, and the partition plate 11 The rear end side of 11 is formed to fit into the insertion hole 10b.
【０００８】 この熱交換器によれば、仕切板１１の先端が挿入穴１０ａから視認できるため 、仕切状態に不具合が生じているか否か簡単に判断でき、熱交換器の性能の低下 を防止できる。[0008] According to this heat exchanger, the tip of the partition plate 11 is visible from the insertion hole 10a. , you can easily determine whether there is a problem with the partition condition, and prevent a decrease in the performance of the heat exchanger. can be prevented.
【０００９】 しかしながら、この仕切板構造においても、仕切板１１の接触端面とヘッダ− ２の周壁２ａとの間に寸法誤差を生じているときは、図５の(b) に示すように、 この接触端面と周壁２ａとの間に間隙Ａが形成されるため、製作上において高い 寸法精度が要求され、製造コストの上昇を招き不利なものとなっていた。[0009] However, even in this partition plate structure, the contact end surface of the partition plate 11 and the header If there is a dimensional error between the peripheral wall 2a and the peripheral wall 2a, as shown in FIG. Since a gap A is formed between this contact end surface and the peripheral wall 2a, the manufacturing cost is high. Dimensional accuracy is required, which is disadvantageous as it increases manufacturing costs.
【００１０】 このようにヘッダ−２を上下に仕切る仕切板８，１１についての従来例を説明 したが、このような問題点はヘッダ−を軸方向に左右に仕切る仕切板についても 同様のことがいえる。即ち、図示しないが、特開昭６４−６７５９２号公報にお いてヘッダ−を左右に仕切る仕切板が開示されている。しかしながら、この仕切 板はヘッダ−の内面に単に接触して配置されているため、この仕切板とヘッダ− との間に間隙が形成されるおそれがあった。0010 A conventional example of the partition plates 8 and 11 that partition the header 2 into upper and lower parts will be explained. However, this problem also applies to the partition plate that divides the header into left and right sides in the axial direction. The same thing can be said. That is, although not shown in the figure, it is described in Japanese Patent Application Laid-open No. 64-67592. A partition plate is disclosed that partitions the header into left and right sides. However, this partition Since the plate is placed simply in contact with the inner surface of the header, this partition plate and the header There was a risk that a gap would be formed between the two.
【００１１】 本考案の目的は前記従来の問題点に鑑み、ヘッダ−に仕切板の接続代を形成す ることにより、確実に熱交換媒体の漏れを防止できる熱交換器を提供することに ある。[0011] In view of the above-mentioned conventional problems, the purpose of this invention is to form a connection allowance for the partition plate on the header. By doing so, we aim to provide a heat exchanger that can reliably prevent leakage of the heat exchange medium. be.
