翅片式散热器、翅片式热交换器是气体与液体热交换器中使用*为广泛的一种换热设备。它通过在普通的基管上加装翅片来达到强化传热的目的。基管可以用钢管；不锈钢管；铜管等。翅片也可以用钢带；不锈钢带，铜带，铝带等，我公司基管选用铜管，翅片选用优质的铜翅片和铝翅片。
Finned radiators and heat exchangers are the most widely used heat exchange equipment in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to the ordinary base tube radiators. The base pipe can be steel pipe,stainless steel pipe, copper pipe and so on. The fins can also be steel strips; stainless steel strips, copper strips and aluminum strips etc.Weichuang Radiator uses copper tubes for the base tube, and high-quality copper fins and aluminum fins for the fins.
翅片的片距主要是考虑积灰，结尘，易清洗等因素，同时需严格符合设备对压力降等要求。排列时，管与管之间的间距不宜过大，一般>1mm以上适合布管即可。在换热的过程中，空气在流经翅片式热交换器和翅片式散热器时，主要是翅片正反二个面参与换热。二支翅片管中间部位只有少量的辐射传热，换热效果不明显。此部位由于无翅片，无阻力，空气容易穿透。在空气加热的过程中，未经换热的冷空气会与从翅片中间穿过的已加热热空气形成中和，反而降低了换热的效果，对比国外的翅片管换热器，管间距仅比翅片外径大0.5mm,可见翅片管排列时，管间距的重要性。
The fin pitch mainly considers factors such as dust accumulation, dust formation, and easy-cleaning.It must strictly comply with the equipment's pressure drop requirements. When arranging, the distance between the tube and the tube should not be too large, generally> 1mm is suitable for tube layout. In the process of heat exchange, when the air flows through the finned heat exchanger and the finned radiator, the front and back sides of the fins mainly participate in the heat exchange. There is only a small amount of radiant heat transfer in the middle of the two finned tubes, and the heat transfer effect is not obvious. Since this part has no fins and resistance, the air is easy to penetrate. In the process of air heating, the unheated cold air will neutralize the heated hot air passing through the middle of the fins, which will reduce the heat exchange effect. Compared with foreign finned tube heat exchangers, the tube spacing is only 0.5mm larger than the outer diameter of the fins, which shows the importance of tube spacing when finned tubes are arranged.
