高周波溶接(HFWの) フィンチューブ

High Frequency Welded fin tube also called solid type fin tube,use steel or stainless steel strip directly welded to tube surface by HFW.Can improving heat transfer efficiency much more than bare tube.Due to the tight welding of the fins to the base tube, these finned tubes are often used in vibrating conditions.Fin type have Serrated fin and flat fin.

顔立ち
1. Because of the fast welding speed and the strong self-cooling effect of the welded parts, not only the heat-affected zone is small, but also the oxidation is not easy to occur, so the organization and performance of the weld is very good.
2. Low contact heat resistance, high stability, anti-dust accumulation ability.
3. Large heat exchange area.

アプリケーション:

Air Cooler, Charge Air Chiller, コンデンサー, Evaporator, Fluid Cooler, Gas Cooler, Oil Cooler, Radiator, Refrigeration, Steam to Air Heat Exchanger, superheater etc.

パッケージ:

In bundles, plywood cases, wooden cases with water-proof package, 等.
High frequency welding finned tube Function
高周波溶接フィン付きチューブは、フィン付きチューブの一種です, 主に高周波溶接で溶接され、新しいタイプの優れた放熱要素です. 高周波溶接フィン付きチューブは高周波電流で溶接されます, 溶接方法は信頼性が高く、優れています, 溶接シームが小さい, そして、ラジエーターの表面はより頑丈で美しいです.

高周波溶接フィン付きチューブは、フィン付きチューブラジエーターでよく使用されるヒートシンクエレメントです. ラジエーターのベースチューブに高周波溶接フィン付きチューブを溶接すると、ラジエーターの熱交換器側の熱伝達率が向上し、ラジエーターの放熱効果が高まります, また、優れた放熱効果により、フィン付きチューブはますます人気が高まっています.

高周波溶接フィン付きチューブは高周波電流で溶接されます, ラジエーターのコンパクトさを高め、操作プロセスにおける高周波溶接フィン付きチューブラジエーターの安全性を向上させることができます. 高周波溶接プロセスは、基本的な溶接プロセスを改良およびアップグレードしたプロセスです, これはまた、より優れた溶接プロセスです.

The more excellent welding process adopted for high-frequency welded finned tubes, the faster the welding speed and the narrower the weld seam, the more beautiful the appearance of the radiator. High-frequency welded finned tube has a simple and generous appearance, mainly in silver and gray, and can be suitable for a variety of styles of decoration, which is widely used in the field.

High frequency welded spiral finned tube is one of the most widely used spiral finned tubes, and is now widely used in power, metallurgy, waste heat recovery in cement industry and petrochemical industry.
High frequency welded finned tubes are highly adaptable and widely used, and have been widely used in a variety of fields such as industry and agriculture. High-frequency welded finned tubes are easy to operate, and users can operate them flexibly and simply to achieve the basic purpose of raising indoor temperature and providing comfort to people in the room.

High frequency welding spiral finned tube is in the steel strip winding steel pipe at the same time, the use of high-frequency current skin effect and proximity effect, the steel strip and the outer surface of the steel pipe heating, until the plastic state or melting, in the winding steel strip under a certain pressure to complete the welding. This high frequency welding is actually a solid-phase welding. Compared with inlay, brazing (or overall hot-dip galvanizing), it is more advanced in terms of product quality (high welding rate of fins, まで 95%), productivity and automation.
