Description
本発明は、熱交換器の製造等に用いられるろう付用アルミニウム合金材およびアルミニウム合金材のろう付方法に関する。 The present invention relates to an aluminum alloy material for brazing used for manufacturing a heat exchanger and the like, and a brazing method for an aluminum alloy material.
例えば、自動車のエアコンディショナ装置などに用いられるアルミニウム合金製の熱交換器の製造では、部品の接合はろう付が主体である。こうした熱交換器の製造にあたっては、例えば、母材より融点が低いろう材を予め母材の両表面に貼り合わせたクラッド材（ブレージングシート）をフィン材に適用し、押出加工で製造した扁平な多穴管を冷媒を通すチューブに適用する。そして、押出加工で製造したパイプをヘッダに適用して、これらを治具で組付け、酸化皮膜を破壊するためのフラックスを塗布した後、ろう付炉に投入して所定温度にて所定時間これを保持することで、ろう付を行い、組み立てられた熱交換器を得ている。 For example, in the manufacture of an aluminum alloy heat exchanger used for an air conditioner device of an automobile, parts are mainly joined by brazing. In manufacturing such a heat exchanger, for example, a clad material (brazing sheet) in which a brazing material having a melting point lower than that of the base material is previously bonded to both surfaces of the base material is applied to the fin material, and the flat material manufactured by extrusion processing is used. The multi-hole tube is applied to the tube through which the refrigerant passes. Then, pipes manufactured by extrusion are applied to the header, assembled with a jig, applied with a flux for breaking the oxide film, and then put into a brazing furnace for a predetermined time at a predetermined temperature. By holding the brazing, the assembled heat exchanger is obtained.
しかし、上述したような組立加工工程におけるフラックスの塗布は、無駄になるフラックスの量が多く、また、飛散したり蒸発したフラックスが作業環境を汚すため、衛生環境上の懸念があり、あわせて製造コストの上昇をもたらすという課題があった。また、プレージングシートのフィン材の加工時に、表面に貼り合せたろう材（Ａｌ−Ｓｉ合金）の硬さゆえに、コルゲート加工機の加工歯の寿命を短くしてしまうという課題があった。 However, the application of flux in the assembly process as described above involves a lot of wasted flux, and the scattered or evaporated flux pollutes the work environment. There was a problem of increasing costs. Further, when processing the fin material of the pressing sheet, there is a problem that the life of the processing teeth of the corrugating machine is shortened due to the hardness of the brazing material (Al—Si alloy) bonded to the surface.
このような課題に対応するために、ブレージングシートを使わずに、組付け後のフラックス塗布を行なわないプロセスとして、粉末ろうとフラックスをアクリル系樹脂バインダで混合し、これらを押出扁平管の表面に適当厚さで塗布した後、クラッド材でないアルミニウム板をフィン材に適用してコンデンサを製造する方法が知られている（特許文献１）。また、こうした製造方法におけるフラックスにＫＺｎＦ３ を用いて、還元作用により、フラックスからＺｎを扁平な多穴管表面に析出させて肉厚方向に拡散し、防食上有意な特性（多穴管表面の犠牲陽極効果）を発揮できるプロセスも提示されている。
しかしながら、上述したような、粉末ろう、ＫＺｎＦ３ フラックス、及び樹脂バインダを用いるプロセスでは、ヘッダ管内部など閉塞された（あるいは半閉塞状態も含む）部位で、ろう付加熱時に塗布膜層が変質してしまい、適正なろう付加工が難しいという課題があった。場合によっては、フィレットが全く形成されないという製造上の課題もあった。 However, in the process using powder brazing, KZnF 3 flux, and resin binder as described above, the coating film layer is altered at the time of brazing applied heat at the clogged (or partially clogged) site such as the header pipe. As a result, there is a problem that proper brazing is difficult. In some cases, there was a manufacturing problem that no fillet was formed.
本発明は、上記事情に鑑みてなされたものであって、ろう付箇所の変質やろう付不良が無く、かつ、簡単な工程で低コストにろう付を可能にする、ろう付用アルミニウム合金材およびアルミニウム合金材のろう付方法を提供することを目的とする。 The present invention has been made in view of the above circumstances, and there is no deterioration of brazing points or brazing defects, and brazing can be performed at a low cost by a simple process, and the brazing aluminum alloy material. And it aims at providing the brazing method of an aluminum alloy material.
上記の目的を達成するために、本発明によれば、Ｓｉ粉末、または／及びＡｌ―Ｓｉ合金粉末を含むろう材と、フッ化物フラックスと、樹脂バインダとを混合したろう付用組成物が塗布されたろう付用アルミニウム合金材であって、前記フッ化物フラックスは、Ｋ−Ｚｎ−Ｆからなるフッ化物と、Ｋ−Ａｌ−Ｆからなるフッ化物とを、重量比が１００：１〜１００：１００の範囲内で混合したものであることを特徴とするろう付用アルミニウム合金材が提供される。 In order to achieve the above object, according to the present invention, a brazing composition comprising a mixture of a brazing material containing Si powder or / and Al-Si alloy powder, a fluoride flux, and a resin binder is applied.

In addition, when the brazing composition is applied, a flux amount of K-Zn-F and K-Al-F is applied to the aluminum alloy material in the range of 1 to 40 g / m 2 as a coating amount when dried. It only has to be done.
また、本発明によれば、Ｓｉ粉末、または／及びＡｌ―Ｓｉ合金粉末を含むろう材と、フッ化物フラックスと、樹脂バインダとを混合したろう付用組成物が塗布されたろう付用アルミニウム合金材を用いるアルミニウム合金材のろう付方法であって、Ｋ−Ｚｎ−Ｆからなるフッ化物を含む前記ろう付用組成物が塗布された領域以外の部材の表面に、Ｋ−Ａｌ−Ｆからなるフッ化物フラックスを、Ｋ−Ｚｎ−Ｆからなるフッ化物フラックスとの重量比が１００：１〜１００：２００の範囲内となるように制御して塗布したことを特徴とするアルミニウム合金材のろう付方法が提供される。 Further, according to the present invention, an aluminum alloy material for brazing coated with a brazing composition in which a brazing material containing Si powder or / and Al-Si alloy powder, a fluoride flux, and a resin binder is applied. A brazing method of an aluminum alloy material using K-Al-F on a surface of a member other than a region where the brazing composition containing a fluoride made of K-Zn-F is applied. A brazing method for an aluminum alloy material, characterized in that a fluoride flux is applied so as to have a weight ratio with a fluoride flux comprising K-Zn-F in the range of 100: 1 to 100: 200. Is provided.
前記フッ化物フラックスのうち、Ｋ−Ｚｎ−Ｆからなるフッ化物はＫＺｎＦ３ であり、Ｋ−Ａｌ−Ｆからなるフッ化物はＫＡｌＦ４ または／及びＫ３ＡｌＦ６であればよい。前記ろう付用組成物を塗布する際に、Ｋ−Ｚｎ−Ｆからなるフラックス量として乾燥時塗布量で１〜４０ｇ／ｍ２ の範囲でアルミニウム合金材のろう付箇所に塗布され、また、前記Ｋ−Ａｌ−Ｆからなるフッ化物フラックスは、前記ろう付用組成物が塗布された領域以外の部材の表面に、乾燥時塗布量で０．０１〜８０ｇ／ｍ２ の範囲で塗布されればよい。 Of the fluoride fluxes, the fluoride composed of K—Zn—F may be KZnF 3 , and the fluoride composed of K—Al—F may be KAlF 4 and / or K 3 AlF 6 .

また、本発明によれば、上述したアルミニウム合金材のろう付方法を用いてろう付されたことを特徴とする熱交換器が提供される。 Moreover, according to this invention, the heat exchanger characterized by brazing using the brazing method of the aluminum alloy material mentioned above is provided.
本発明のろう付用アルミニウム合金材によれば、Ｋ−Ｚｎ−Ｆ成分が、ろう付温度に昇温される前から活性度が増し、粉末Ｓｉ及びアルミニウム合金材表面の酸化皮膜を破壊するとともに、Ｚｎが還元されてアルミニウム合金材上に析出して、耐腐蝕性を確保する上で有効な犠牲陽極層をアルミニウム合金材表面に形成する役割を果たす。また、Ｚｎの還元作用と相まって、ろうの広がりを促進させる。 According to the aluminum alloy material for brazing of the present invention, the K-Zn-F component increases in activity before being heated to the brazing temperature, and destroys the powder Si and the oxide film on the surface of the aluminum alloy material. Zn is reduced and deposited on the aluminum alloy material, and plays a role of forming a sacrificial anode layer effective on ensuring the corrosion resistance on the surface of the aluminum alloy material. In addition, in combination with the reduction action of Zn, the spreading of the wax is promoted.
また、Ｋ−Ａｌ−Ｆ成分も、ろう付温度に昇温される前から活性度が増し、粉末Ｓｉ及びアルミニウム合金材表面の酸化皮膜を破壊する。さらに、Ｋ−Ｚｎ−Ｆ成分とともに、フラックスの溶融状態を長く維持し、アルミニウム合金材表面を覆って、新たな酸化膜の生成を防止する役割を果たす。こうした覆い効果により、閉塞された（あるいは半閉塞状態も含む）部位でも塗布膜層が変質することがなく、不安定なろう付性を大きく改善することが可能になる。 The K-Al-F component also increases its activity before being heated to the brazing temperature, and destroys the powder Si and the oxide film on the surface of the aluminum alloy material. Further, together with the K—Zn—F component, it keeps the molten state of the flux long, covers the surface of the aluminum alloy material, and prevents the generation of a new oxide film. Due to such a covering effect, the coating film layer does not change even in a blocked (or including a semi-closed state), and the unstable brazing property can be greatly improved.
以下、本発明の実施の形態について、図面を交えて説明する。図１は、本発明のろう付用アルミニウム合金材を使用して形成したアルミニウム製の熱交換器の一例を示す斜視図である。熱交換器１０は、ヘッダパイプ１１と称される左右一対の管体と、そのヘッダパイプ１１の間に互いに平行に間隔を空けて設けられたアルミニウム合金材からなる多数のチューブ（熱交換用チューブ）１２と、チューブ１２同士の間に設けられたフィン（放熱板）１３とで構成されている。
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of an aluminum heat exchanger formed using the brazing aluminum alloy material of the present invention. The
こうした熱交換器１０は、各チューブ１２の内部に形成される流体通路（図示せず）と、ヘッダパイプ１１の内部空間（図示せず）を連通させ、ヘッダパイプ１１の内部空間と各チューブ１２の流体通路に冷媒等の流体を循環させ、フィン１３を介して効率良く熱交換を行うものである。
Such a
請求項１ないし３に関して、各チューブ１２の外表面に、Ｓｉ粉または／及びＡｌ―Ｓｉ合金粉末を含むろう材と、Ｋ−Ｚｎ−Ｆからなるフッ化物及びＫ−Ａｌ−Ｆからなるフッ化物フラックス、及びバインダとを混合したろう付用組成物を塗布して、ろう付用アルミニウム合金材を構成する。 4. A brazing material containing Si powder or / and Al—Si alloy powder, a fluoride composed of K—Zn—F, and a fluoride composed of K—Al—F on the outer surface of each tube 12 A brazing composition in which a flux and a binder are mixed is applied to form an aluminum alloy material for brazing.
図２は請求項４ないし７に関し、図１に示すヘッダパイプ１１とチューブ１２との接合部分を示す拡大断面図である。チューブ１２は、表面にろう付用組成物２２が塗布されたろう付用アルミニウム合金材２１から形成される。ろう付用組成物２２は、Ｓｉ粉末、または／及びＡｌ―Ｓｉ合金粉末を含むろう材と、フッ化物フラックスおよび樹脂バインダとを混合して形成される。こうした、ろう付用組成物２２をアルミニウム合金材に塗布して、ろう付用アルミニウム合金材２１が形成される。

The fluoride flux constituting the
また、こうしたフッ化物フラックスのうち、Ｋ−Ｚｎ−Ｆからなるフッ化物はＫＺｎＦ３ であればよく、Ｋ−Ａｌ−Ｆからなるフッ化物ではＫＡｌＦ４ または／及びＫ３ＡｌＦ６ が好ましく採用される。 Of these fluoride fluxes, the fluoride composed of K—Zn—F may be KZnF 3 , and the fluoride composed of K—Al—F preferably employs KAlF 4 and / or K 3 AlF 6. .
こうしたフッ化物フラックスのうち、Ｋ−Ｚｎ−Ｆ成分は、ろう付温度に昇温される前の約５２０℃から活性度が増し、粉末Ｓｉ及びアルミニウム合金材表面の酸化皮膜を破壊するとともに、Ｚｎが還元されてアルミニウム合金材上に析出して、耐腐蝕性を確保する上で有効な、犠牲陽極層をアルミニウム合金材表面に形成する役割を果たす。また、Ｚｎの還元作用と相まって、ろうの広がりを促進させる。 Among these fluoride fluxes, the K—Zn—F component increases in activity from about 520 ° C. before being heated to the brazing temperature, and destroys the oxide film on the surface of the powder Si and the aluminum alloy material. Is reduced and deposited on the aluminum alloy material, and plays a role in forming a sacrificial anode layer on the surface of the aluminum alloy material, which is effective in ensuring corrosion resistance. In addition, in combination with the reduction action of Zn, the spreading of the wax is promoted.
また、フッ化物フラックスのＫ−Ａｌ−Ｆ成分は、ろう付温度に昇温される前の約５４０℃から活性度が増し、粉末Ｓｉ及びアルミニウム合金材表面の酸化皮膜を破壊する。さらに、上述したＫ−Ｚｎ−Ｆ成分とともに、フラックスの溶融状態を長く維持し、アルミニウム合金材表面を覆って、新たな酸化膜の生成を防止する役割を果たす。こうした覆い効果により、閉塞された（あるいは半閉塞状態も含む）部位でも塗布膜層が変質することがなく、不安定なろう付性を大きく改善することが可能になった。 Further, the K-Al-F component of the fluoride flux increases in activity from about 540 ° C. before being heated to the brazing temperature, and destroys the powder Si and the oxide film on the aluminum alloy material surface. Further, together with the above-described K—Zn—F component, the melted state of the flux is maintained for a long time, and the aluminum alloy material surface is covered to prevent the formation of a new oxide film. Due to such a covering effect, the coating film layer does not change even in a blocked (or semi-blocked) part, and it is possible to greatly improve unstable brazing.
