Fin radiator is a kind of heat exchange equipment that is widely used in gas and liquid heat exchangers. It achieves enhanced heat transfer by adding fins to ordinary base tubes. The base pipe can be made of steel pipe, stainless steel pipe, copper pipe, etc., and the fins can also be made of steel belt, stainless steel belt, copper belt, aluminum belt, etc. These finned radiators can be divided into winding type, string type, welding sheet type, and rolling type in the fin structure form.
Wound fin tube radiator is one of them, which uses steel strip to wind around the base tube to form fins, which has the advantages of simple structure, convenient production and high heat transfer performance, so it is widely used in the industrial field. The tandem finned tube radiator uses the string tube as the fin, which has the characteristics of high heat transfer efficiency and corrosion resistance, and is suitable for chemical industry, refrigeration and other fields. The solder fin tube radiator is formed by welding the steel strip and the base pipe together to form a fin, which has the characteristics of high heat transfer efficiency and strong pressure resistance, and is suitable for high temperature and high pressure occasions. The rolled fin tube radiator is formed by rolling the steel strip and base pipe at high temperature to form fins, which has the characteristics of high heat transfer efficiency and corrosion resistance, and is also suitable for chemical industry, refrigeration and other fields.
At present, the most widely used is the steel-aluminum composite finned tube, which uses the pressure resistance of the steel pipe and the thermal conductivity of the aluminum to be compounded on a special machine tool. The contact thermal resistance is almost zero at 210 °C. This finned radiator has a high cost performance ratio and can meet the needs of different fields. Whether in the industrial field or in the civil field, finned heat sinks have been widely used for their efficient heat transfer performance and high reliability. With the continuous progress of technology and the continuous change of market demand, finned radiators will continue to develop and improve, bringing more convenience and benefits to people's lives and production.
