以下本発明につき、実施例を用いて説明する。 The present invention will be explained below using examples.
第１図は本発明の一実施例全説明するための図である。FIG. 1 is a diagram for fully explaining one embodiment of the present invention.
この実施例においては、第１及び第２ツノ系の溶剤１例

ＣＣｌ２Ｆ２． ＣＨＣｌＦ２ＣＣｌ２Ｆ−ＣＣ１Ｆ、
等が用いられ得る。フラックスはＫＡｌＦ３とに、Ａｔ
Ｆ、との混合物から成る。The second tank 2 contains a flux-solvent solution 4 in which a non-corrosive flux is dispersed in a fluorine-based solvent. The fluorocarbon solvent contained in the second tank 2 is as follows:
CCl2F2. CHClF2CCl2F-CC1F,
etc. can be used. The flux is KAlF3 and At
It consists of a mixture of F.
使用し得るフッソ系溶剤の種類を第１表に示す。これら
のフッソ系溶剤は物性特性が安定している為、容易にフ
ラックスとの混合液となり得る。Table 1 shows the types of fluorocarbon solvents that can be used. Since these fluorine-based solvents have stable physical properties, they can easily form a mixture with flux.
第１表
アルミ製熱交換器の製造に当シ、アルミニウム又はアル
ミニウム合金よシ作られた熱交換器部材５を用意する。Table 1 To manufacture an aluminum heat exchanger, a heat exchanger member 5 made of aluminum or an aluminum alloy is prepared.
熱交換器部材５は１例えば。For example, the heat exchanger member 5 is one.
多数の冷媒通路を有する偏平管を蛇行状に成形してなる
冷媒管６にコルゲートフィン７を組み合わせたものであ

の槽２に挿入浸漬する。第２の槽２のフラックス−溶剤
液４のフラックスは５〜１５％の濃度であシ、溶剤中に
攪拌分散されている。フラックス−溶剤液４中に浸漬さ
れた熱交換器部材５を数秒後にとυ出す。Corrugated fins 7 are combined with a refrigerant tube 6 formed by forming a meandering flat tube having a large number of refrigerant passages. Such a heat exchanger member 5 is passed through the first tank 1 and then transferred to the second tank.
Insert into tank 2 and immerse. The flux in the flux-solvent solution 4 in the second tank 2 has a concentration of 5 to 15%, and is stirred and dispersed in the solvent. The heat exchanger member 5 immersed in the flux-solvent solution 4 is removed after a few seconds.
この結果、熱交換器部材５にフラックスが均一な塗布皮
膜のように付着される。この時、フック系溶剤は沸点が
低い為、瞬時的に蒸発される。As a result, the flux adheres to the heat exchanger member 5 like a uniform coating film. At this time, since the hook-based solvent has a low boiling point, it evaporates instantaneously.
したがってフラックス皮膜はより均一に作られる。Therefore, the flux film is made more uniform.
次にこのフラックスの付着した熱交換器部材５に、乾燥
工程を経ることなくろう付装置８にてろう付処理を施す

熱交換器部材５に細部に至るまで付着される。さらに蒸
発蓄熱も水に比し小さい為。Table 2 Accordingly, the flux contained in the solvent is adhered to the aluminum heat exchanger member 5 down to the smallest detail. Furthermore, the evaporative heat storage is smaller than that of water.
よシ効果が大きい。It has a great positive effect.
またフッソ系溶剤は物性的に安定性が大であシ、アルミ

部に冷却ゾーン９を設ける事により 、 ｔｏｏ％近い
回収が可能であり、コスト上非常に有利である。Suitable for flux-solvent liquids. By providing a cooling zone 9 in the upper part of the second tank 2 for applying the flux, nearly 20% of the gas during evaporation of the solvent can be recovered, which is very advantageous in terms of cost.
第３表は、溶剤が水である場合とＲ−１１３である場合
とを比較して示す。Table 3 shows a comparison between the case where the solvent is water and the case where R-113 is used.
第３表
なお、熱交換器部材５をフラックス−溶剤液４中に浸漬
する代シに、熱交換器部材５に７ラツクスー溶剤液４を
スプレー等によって吹きつけてもよい。Table 3 Note that instead of immersing the heat exchanger member 5 in the flux-solvent solution 4, the heat exchanger member 5 may be sprayed with the flux-solvent solution 4 by spraying or the like.
上述したように本発明によれば、熱交換器部材の表面に
フラックス膜が均一に形成される。As described above, according to the present invention, a flux film is uniformly formed on the surface of the heat exchanger member.
