【発明の属する技術分野】
本発明は、熱交換器用タンクに係り、詳しくはチューブ挿通穴の設けられる座板部の形状に関するものである。
【0002】
【従来の技術】
近時、冷房用のコンデンサをラジエータの前面に連結したいわゆる一体型熱交換器が考案されるようになってきており、このような一体型熱交換器では、例えば、特開平3−177795号公報等に開示されるような一体型熱交換器用タンクが開示されている。
【0003】
図7は、特開平3−177795号公報に開示される一体型熱交換器を示すもので、この一体型熱交換器は、ラジエータとして使用する第1熱交換器1と冷房用のコンデンサとして使用される第2熱交換器2を並列に配置している。
第1熱交換器1は、一定間隔をおいて対向配置される一対のアルミニウム製の上側タンク3と下側タンク4とをアルミニウム製のチューブ5で連結し、第2熱交換器2は、一定間隔をおいて対向配置される一対のアルミニウム製の上側タンク6と下側タンク7との間をアルミニウム製のチューブ8で連結している。
【0004】
そして、図8および図9に示すように、第1熱交換器1のタンク3,4には、座板部3a,4aに、バーリング加工によってチューブ挿通穴10を穿設している。
【0005】
また、図10に示すように、第1熱交換器1と第2熱交換器2のアルミニウム製のチューブ5とチューブ8は、両者に跨る幅のアルミニウム製のフィン9に接している。即ち、第1熱交換器1と第2熱交換器2は、共通のフィン9によって放熱部(コア部)11を構成している。
第1熱交換器1のタンク3,4と第2熱交換器2のタンク6,7と放熱部(コア部)11は、一体的にろう付けされている。
【0006】
【発明が解決しようとする課題】
しかしながら、このような従来の一体型熱交換器では、第1熱交換器1のタンク3,4の座板部3a,4aと第2熱交換器2のタンク6,7の座板部6a,7aに、バーリング加工によってチューブ挿通穴10を穿設するが、第1熱交換器のタンク3,4の座板部3a,4aは平面のため、図8および図9に示すように、チューブ挿入穴10の平行部10bには立上がり部10cができるが、チューブ挿通穴10のアール形状をなす両端部10aに立上がり部10がほとんどない。
【0007】
そのため、チューブ挿通穴10に差し込まれたチューブ5,8と両端部10aとが接する部分が少なく、ろう付け時にろうが確実に集まりにくいという問題がある。
このような問題は、図8、図9に示すような平面にチューブ挿通穴10を穿設した座板構造を有する熱交換器用タンクにおいて共通しており、一体型熱交換器特有の問題ではない。
【0008】
本発明は、かかる従来の問題点を解決するためになされたもので、その目的は、チューブ挿通穴の両端部へのろう溜まりを可能とした熱交換器用タンクを提供することにある。
【0009】

【0014】
【発明の実施の形態】
以下、本発明の詳細を図面に示す実施形態について説明する。
図1ないし図3は、請求項1記載の発明に係る熱交換器用タンクの一実施形態を示しており、図において、20は座板部を表す。
座板部20には、底面側20aからバーリング加工によりチューブ挿通穴21が穿設され、矢印で示す間に位置する平行部21bには立上がり部21aが立ち上がっている。このチューブ挿通穴21は、そのアール形状をなす両端部22,23が、座板部20の立上がり壁24の際まで延出している。立上がり部21aは、立上がり壁24の近くまで形成されている。
【0015】
ここで、座板部20は、覆い部26と連結されて本実施形態に係る熱交換器用タンク27を構成している。
チューブ挿通穴21には、チューブ25が挿通される。そして、チューブ挿通穴21とチューブ25とは、常法に従って一体にろう付けされる。
【0016】
以上のように構成された熱交換器用タンク27によれば、チューブ25をチューブ挿通穴21に挿通すると、チューブ25と座板部20の立上がり壁24との隙間に毛細管現象によりろう材が集まり、チューブ挿通穴21の両端部22,23に近接している座板部20の立上がり壁24との間でろう材の溜まり部28が形成され、チューブ挿通穴21に挿通されたチューブ25との間でのろう切れを防止することができる。
【0017】
本実施形態では、座板部20と覆い部26とを一体とした場合について説明したが、座板部20と覆い部26とを個別に形成し、シール部材を介して結合する構造としても良い。また、形状も断面形状が矩形に限らず、蒲鉾形や丸形であっても、チューブ挿通穴21が設けられる面が平面であれば良い。
図4ないし図6は、請求項2ないし請求項5記載の発明に係る熱交換器用タンクの一実施形態を示しており、図において、31はラジエータを構成する第1熱交換器を、32はコンデンサを構成する第2熱交換器を示している。
【0018】
第1熱交換器用タンク33,34と第2熱交換器用タンク35,36は、アルミニウムからなり押出成形により一体に形成されている。
第1熱交換器用タンク33,34は、箱断面形状をなし、第2熱交換器用タンク35,36は、丸断面形状をなしている。第2熱交換器用タンク35,36は、第1熱交換器用タンク33,34の側壁に形成される平面部37の下部に当接するとともに連結部38を介して一体になっている。第1熱交換器31と第2熱交換器32は、各チューブ挿通穴39,40,41,42の軸心39a,40a,41a,42aを平行にして、第1熱交換器用タンク33,34の平面部37に第2熱交換器用タンク35,36を当接している。
【0019】
ここで、平面部37は、第2熱交換器用タンク35,36側の一側面奥行き方向全域に形成されており、高さ方向は連結部38の寸法と同じで良く、第1熱交換器用タンク33,34の座板部43,44に対して垂直になっている。
また、第1熱交換器用タンク33,34の座板部43,44と立上がり壁49および第1熱交換器用タンク33,34の座板部43,44と平面部37との内側の角部60がほぼ90゜になっている。
【0020】
そして、両タンク33,34、35,36は、図4に示すように、座板部43,44,45,46が一点鎖線で示す水平線H上に位置している。
第1熱交換器用タンク33,34の座板部43,44には、底面側43a,44aからバーリング加工によりチューブ挿通穴39,40が穿設され、図6に示すように、矢印で示す間に位置する平行部39b,40bには立上がり部39a,40aが立ち上がっている。
【0021】
このチューブ挿通穴39,40は、図6に示すように、そのアール形状をなす両端部47,48が、座板部43,44の立上がり壁49の際まで延出している。立上がり部39a,40aは、立上がり壁49の近くまで形成されている。
【0022】
このチューブ挿通穴39,40には、チューブ50が挿通されている。
チューブ挿通穴41,42には、チューブ54が挿通されている。
チューブ50,54には両者に跨るフィン55が配置されている。
第1熱交換器用タンク33,34、チューブ50と第2熱交換器用タンク35,36、チューブ54とフィン55とは、常法に従って一体にろう付けされる。
【0023】
以上のように構成された本実施形態によれば、第1熱交換器用タンク33,34の座板部43,44の各チューブ挿通穴39,40にチューブ50を挿通すると、チューブ挿通穴39,40のアール形状をなす両端部47,48に近接している座板部43,44の立上がり壁49との間でろう材の溜まり部56,57が形成され、チューブ挿通穴39,40に挿通されたチューブ50との間でのろう切れを防止することができる。
【0024】
また、第1熱交換器用タンク33,34と第2熱交換器用タンク35,36が、アルミニウム製の一体押出成形品であるから、従来例のように両者をろう付けする必要がない。従って、第1熱交換器用タンク33,34と第2熱交換器用タンク35,36をろう付けするに際し、両者の位置合わせを行うという面倒な作業が不要となる。
【0025】
また、第1熱交換器用タンク33,34と第2熱交換器用タンク35,36の座板部43,44,45,46を面一にできるので、チューブピッチが狭くなるとともに、無駄なチューブ長さを解消することもできる。
なお、上記実施形態では、第1熱交換器用タンク33,34を箱断面形状とした場合について説明したが、第2熱交換器用タンク35,36との当接部位を確保するための平面部37を形成できれば特にその形状を限定するものではない。特に、第1熱交換器31はラジエータに使用される場合には、コンデンサに比して耐圧性は要求されないからその形状は任意である。
【0026】
【発明の効果】
以上述べたように、請求項1および請求項2記載の発明では、チューブ挿通穴のアール形状をなす両端部に近接している座板部の壁面との間でろう材の溜まり部が形成され、チューブ挿通穴に挿通されたチューブとの間でのろう切れを防止することができ、コーナ部のろう付け性を向上させることができる。
【0027】
請求項3記載の発明では、第1熱交換器用タンクと第2熱交換器用タンクは、各チューブ挿通穴の軸心を平行にして、第1熱交換器用タンクの平面部に第2熱交換器用タンクを当接したものであるから、簡単な構造で放熱部(コア部)を薄くすることができる。
請求項4記載の発明では、第1熱交換器用タンクと第2熱交換器用タンクをアルミニウムの一体押出成形品で構成すると、従来のようにろう付け作業が不要となる。
【0028】
請求項5記載の発明では、チューブ挿通穴に形成する立上がり部を、立上がり壁の近くまで形成することが可能となり、チューブ挿通穴のアール形状をなす両端部に近接している座板部の壁面との間にろう材の溜まり部を確実に形成することができる。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention shown in the drawings will be described in detail.
1 to 3 show an embodiment of a heat exchanger tank according to the first aspect of the present invention. In the figure, 20 denotes a seat plate portion.
A tube insertion hole 21 is formed in the seat plate portion 20 by burring from the bottom surface side 20a, and a rising portion 21a rises at a parallel portion 21b located between arrows. The tube insertion hole 21 has its rounded ends 22 and 23 extending to the rising wall 24 of the seat plate 20. The rising portion 21 a is formed up to the vicinity of the rising wall 24.
[0015]
Here, the seat plate portion 20 is connected to the cover portion 26 to constitute the heat exchanger tank 27 according to the present embodiment.
The tube 25 is inserted into the tube insertion hole 21. And the tube penetration hole 21 and the tube 25 are integrally brazed according to a conventional method.
[0016]
According to the heat exchanger tank 27 configured as described above, when the tube 25 is inserted into the tube insertion hole 21, the brazing material gathers in the gap between the tube 25 and the rising wall 24 of the seat plate portion 20 by capillary action, A brazing material reservoir portion 28 is formed between the rising wall 24 of the seat plate portion 20 adjacent to both end portions 22 and 23 of the tube insertion hole 21, and between the tube 25 inserted into the tube insertion hole 21. It is possible to prevent the wax from being cut off.
[0017]
In the present embodiment, the case where the seat plate portion 20 and the cover portion 26 are integrated has been described. However, the seat plate portion 20 and the cover portion 26 may be formed separately and coupled via a seal member. . Also, the shape is not limited to a rectangular cross-sectional shape, and the surface on which the tube insertion hole 21 is provided may be a flat surface even if it has a bowl shape or a round shape.
4 to 6 show one embodiment of a heat exchanger tank according to the invention of claims 2 to 5, in which 31 is a first heat exchanger constituting a radiator, and 32 is a heat exchanger tank. The 2nd heat exchanger which comprises a capacitor | condenser is shown.
[0018]
The first heat exchanger tanks 33 and 34 and the second heat exchanger tanks 35 and 36 are made of aluminum and integrally formed by extrusion.
The first heat exchanger tanks 33 and 34 have a box cross-sectional shape, and the second heat exchanger tanks 35 and 36 have a round cross-sectional shape. The second heat exchanger tanks 35 and 36 are in contact with the lower part of the flat surface portion 37 formed on the side walls of the first heat exchanger tanks 33 and 34 and are integrated with each other via a connecting portion 38. In the first heat exchanger 31 and the second heat exchanger 32, the first heat exchanger tanks 33, 34 are arranged such that the shaft centers 39a, 40a, 41a, 42a of the tube insertion holes 39, 40, 41, 42 are parallel to each other. The second heat exchanger tanks 35 and 36 are in contact with the flat surface portion 37.
[0019]
Here, the flat surface portion 37 is formed in the entire area of one side surface in the depth direction on the second heat exchanger tanks 35, 36 side, and the height direction may be the same as the dimension of the connecting portion 38, and the first heat exchanger tank It is perpendicular to the seat plate portions 43, 44 of 33, 34.
Also, the corner portions 60 inside the seat plate portions 43 and 44 of the first heat exchanger tanks 33 and 34 and the rising wall 49 and the seat plate portions 43 and 44 of the first heat exchanger tanks 33 and 34 and the flat portion 37. Is almost 90 °.
[0020]
And as shown in FIG. 4, both tanks 33, 34, 35, and 36 are located on the horizontal line H which the seat-plate parts 43, 44, 45, and 46 show with a dashed-dotted line.
Tube insertion holes 39 and 40 are formed in the seat plate portions 43 and 44 of the first heat exchanger tanks 33 and 34 by burring from the bottom surface sides 43a and 44a, as shown in FIG. Rising portions 39a and 40a are raised at the parallel portions 39b and 40b located in the vertical direction.
[0021]
As shown in FIG. 6 , the tube insertion holes 39 and 40 have both end portions 47 and 48 having a rounded shape extending to the rising wall 49 of the seat plate portions 43 and 44. The rising portions 39 a and 40 a are formed up to the vicinity of the rising wall 49.
[0022]
A tube 50 is inserted through the tube insertion holes 39 and 40.
A tube 54 is inserted through the tube insertion holes 41 and 42.
The tubes 50 and 54 are provided with fins 55 straddling both.
The first heat exchanger tanks 33 and 34, the tube 50 and the second heat exchanger tanks 35 and 36, the tube 54 and the fin 55 are integrally brazed in accordance with a conventional method.
[0023]
According to the present embodiment configured as described above, when the tube 50 is inserted into the tube insertion holes 39, 40 of the seat plate portions 43, 44 of the first heat exchanger tanks 33, 34, the tube insertion holes 39, 40. Brazing material reservoirs 56 and 57 are formed between the rising walls 49 of the seat plate portions 43 and 44 adjacent to both end portions 47 and 48 having a 40-shaped shape, and are inserted into the tube insertion holes 39 and 40. It is possible to prevent the wax breakage between the formed tube 50.
[0024]
In addition, since the first heat exchanger tanks 33 and 34 and the second heat exchanger tanks 35 and 36 are integrally extruded products made of aluminum, it is not necessary to braze them as in the conventional example. Therefore, when the first heat exchanger tanks 33 and 34 and the second heat exchanger tanks 35 and 36 are brazed, the troublesome work of aligning the two becomes unnecessary.
[0025]
In addition, since the seat plate portions 43, 44, 45, 46 of the first heat exchanger tanks 33, 34 and the second heat exchanger tanks 35, 36 can be flush with each other, the tube pitch is reduced and the useless tube length is reduced. This can be solved.
In addition, although the said embodiment demonstrated the case where the tanks 33 and 34 for 1st heat exchangers were made into box cross-sectional shape, the plane part 37 for ensuring the contact part with the tanks 35 and 36 for 2nd heat exchangers. If it can be formed, the shape is not particularly limited.
