1238750 五、發明說明α) 【發明所屬之技術領域】 本發明是關於一種散熱盤管結構之焊接裝置與方法， 尤指一種於焊接過程中、以水冷方式保護焊接鄰近區域之 焊接裝置與方法者。 【先前技術】 請參閱第一圖所示，係為一習知散熱盤管結構1之立 體示意圖；習知之盤管結構1常運用於冷凍空調系統之散 熱裝置上，其組成乃是以多數並列銅管1 2貫穿層疊之散熱 鰭片1 1 (通常為表面塗裝鋁片），而二並列銅管1 2於穿出表 面塗裝鋁片1 1層後，再以一連接彎管1 4 (通常亦以銅管製 成）形成二管路1 2間之連通串聯；在習知技藝中，並列銅 管1 2與連接彎管1 4間之連接係以一焊接製程達成。 請參閱第二圖所示，係為習知散熱盤管結構1並列銅 管1 2與連接彎管1 4間焊接製程之示意圖；當在進行並列銅 管1 2與連接彎管1 4間之焊接前，係先將連接彎管1 4兩端分 別插置入所欲連接二並列銅管1 2之相對應連接管口 1 2 1 中，且於連接管口 1 2 1與連接彎管1 4間放置有適當之焊料2 (通常成環狀）；之後，再於並列銅管1 2與連接彎管1 4之連 接觸上方運用火嘴2加熱，以將焊料融入並列銅管1 2連接 管口 1 2 1與連接彎管1 4間之間隙，完成並列銅管1 2與連接 彎管1 4間之密接。在習知技藝中，前述之焊接製程通常是 以自動化製程實施。 在前述之散熱盤管結構中，因結構材料不是為銅、即1238750 V. Description of the invention α) [Technical field to which the invention belongs] The present invention relates to a welding device and method for a radiating coil structure, particularly a welding device and method for protecting a nearby area by water cooling during the welding process. . [Prior art] Please refer to the first figure, which is a three-dimensional schematic diagram of a conventional cooling coil structure 1; the conventional coil structure 1 is often applied to the cooling device of a refrigeration air-conditioning system, and its composition is juxtaposed by a majority. The copper pipe 1 2 penetrates the laminated heat radiating fins 11 (usually coated with aluminum sheet), and the two parallel copper pipes 12 are coated with aluminum sheet 1 after passing through the surface, and then connect the elbow pipe 1 4 (Usually also made of copper pipes) forming a series connection between the two pipes 12; in the conventional art, the connection between the parallel copper pipes 12 and the connecting elbows 14 is achieved by a welding process. Please refer to the second figure, which is a schematic diagram of the welding process between the parallel copper pipe 12 and the connecting elbow 14 in the conventional cooling coil structure 1; when the parallel copper pipe 12 and the connecting elbow 14 are in parallel, Before welding, the two ends of the connecting elbow 1 4 are respectively inserted into the corresponding connecting mouths 1 2 1 of the two parallel copper pipes 12 to be connected, and the connecting elbow 1 2 1 and the connecting elbow 1 The appropriate solder 2 (usually ring-shaped) is placed in the 4 rooms; then, the connection between the parallel copper pipe 1 2 and the connecting elbow 1 4 is heated by the fire nozzle 2 to integrate the solder into the parallel copper pipe 1 2 The gap between the nozzle 1 2 1 and the connecting elbow 14 is completed, and the close connection between the parallel copper pipe 12 and the connecting elbow 14 is completed. In the conventional art, the aforementioned welding process is usually implemented by an automated process. In the aforementioned heat sink coil structure, because the structural material is not copper, that is,
第7頁 1238750 五、發明說明（2) 為鋁，二者皆為極佳之導熱金屬，是以在焊接製程中，因 材料間之迅速熱傳，常使結構上層（如第一圖所示之A區） 各表面塗裝鋁片1 1表面之塗層受到熱影響而形成一變色區 域（通常為黃黑色），此變色區域A極為突兀，嚴重影響整 體散熱盤管結構1之外觀。 而盤管結構材料導熱性佳之另一缺點，會發生在並列 銅管1 2與連接彎管1 4間之密接上；當焊接因材料導熱快速 而使熱影響區擴大時，其焊料3之熔融狀態即會延長，而 使二管1 2、1 4間之密接產生問題。 請參閱第三圖所示，係為第二圖中B區經焊接完成後 之一放大示意圖；在此一狀況中，因焊接熱影響區之冷卻 速度較慢，且恰好連接彎管1 4與並列銅管1 2連接管口 1 2 1 間之管接間隙4稍大，故熔融狀態之焊料3便即可能會流落 至並列銅管1 2中，並於管接間隙4中留下一如圖所示之細 縫，此細縫明顯地無法通過品管之檢驗，而使焊接製程須 重新來過。 當習知盤管結構1之焊接因材料導熱過快而產生前述 問題時，解決之方法不外是縮減焊接時之熱量輸入（加快 焊接速度、或減少火嘴2之功率），惟減少熱量之輸入卻常 會因熱影響區縮小，而導致焊料3熔融不全、或是提前凝 固，同樣地產生連接彎管1 4與並列銅管1 2間之密接問題。 爰是，如何藉由改良盤管結構1之焊接製程，而能順 利解決前述諸問題，乃是為熟習此類技藝者所歡迎。Page 7 1238750 V. Description of the invention (2) is aluminum, both of which are excellent heat-conducting metals. Because of the rapid heat transfer between materials in the welding process, the upper layer of the structure (as shown in the first figure) is often used. Area A) The coating on the surface of each surface coated with aluminum sheet 11 is affected by heat to form a discolored area (usually yellow and black). This discolored area A is extremely abrupt, which seriously affects the appearance of the overall cooling coil structure 1. Another disadvantage of the good thermal conductivity of the coil structure material will occur in the close connection between the parallel copper pipe 12 and the connecting elbow 14; when the heat-affected zone is enlarged due to the rapid heat conduction of the material, the solder 3 melts. The state will be prolonged, which will cause problems in the tight connection between the two pipes 1, 2, and 14. Please refer to the third figure, which is an enlarged schematic diagram of the B area in the second figure after the welding is completed. In this situation, the cooling speed of the heat affected zone is slow due to welding, and it is just connected to the elbow 14 and The connection gap 4 between the parallel copper pipes 12 and the connection nozzles 1 2 1 is slightly larger, so the molten solder 3 may flow into the parallel copper pipes 12 and leave the same in the connection gap 4 as The thin seam shown in the figure obviously cannot pass the quality control inspection, and the welding process must be repeated. When it is known that the welding of coil structure 1 causes the aforementioned problems due to the excessive heat conduction of the material, the solution is to reduce the heat input during welding (accelerate the welding speed or reduce the power of the flame nozzle 2), but reduce the heat. However, due to the shrinkage of the heat-affected zone, the input 3 often leads to incomplete melting of the solder 3 or solidification in advance, which also causes the problem of tightness between the connecting curved pipe 14 and the parallel copper pipe 12. That is, how to improve the welding process of the coil structure 1 to solve the aforementioned problems smoothly is welcomed by those skilled in this art.
