Product Description

Air heater, also known as finned tube radiator, is a heat exchanger widely used in gas and liquid heat exchanger. All heat and cold exchangers with fins on heat exchange tubes to increase the heat dissipation area can be summarized as "finned tube radiator". Commonly used as hot air or cold air, it is characterized by compact structure and large unit heat exchange area.

 

Features

Generally speaking, the fin tube heat exchanger spacing, slice height is the main factors affecting the fin ratio, medium in the tube and outside the medium fin ratio and heat transfer coefficient will be significant. If there is a large difference in the heat transfer coefficient of the inner and outer film of the tube, the finned tube with a large finned ratio should be selected, such as steam heating air. When there is a single-sided medium phase change, the heat transfer coefficient is very different, such as the exchange of hot and cold air, when the hot air falls below the dew point, finned tube heat exchanger can be used. Bare tubes are usually suitable for heat transfer between air and air without phase change, or between water and water. When using low finned tube, due to the weak heat transfer coefficient during this period, strengthening it will produce a certain effect. However, the excessive fin effect is not obvious, and the contact area between tube and tube is strengthened at the same time. Threaded tube or grooved tube can be used.

 

Process

In the process of copper pipe welding, if the operation is not proper, it is easy to occur defects such as virtual welding, erosion and dissolution, over-burning and burning. Virtual welding is a quality problem that often occurs in the welding process of two devices. The main reasons are as follows:
▪ Small expansion, brazing solder is not easy to enter, resulting in welding is not stable;
▪ Welding heating is not uniform, resulting in part of brazing solder is not completely heated melting;
▪ Oil, oxide, residual carbon and other substances on the surface of the copper tube at the welding place;
▪ Quality of solder itself;
▪ Solder fails to fill the socket or weld the full length of the socket.
