Aluminum finned tube The aluminum tube is rolled as a whole, with no contact thermal resistance, high strength, thermal shock and motor vibration, good thermal expansion performance, and has a considerable extended heat exchange surface. The heat exchange made of this finned tube The heat dissipation effect is significantly better than that of string or wound fin heat exchangers.

Integral finned tube

Rolled finned tube fins are smooth, burr-free, wrinkle-free, beautiful and bright, and easy to clean. When used as components of air heaters and surface coolers, it is easy to remove condensed water on the surface, and it is not easy to dust and condense in drying heating and other occasions. The fins of the rolled finned tube are cross-sectional and trapezoidal, so the fins have high strength and expand the heat dissipation surface, so that the material can be utilized to a greater extent.

Specification and performance table of extruded aluminum finned tube

Structure diagram of extruded aluminum finned tube

The technical characteristics of extruded aluminum finned tube are in the form of a base tube sleeved with an aluminum tube, (the base tube can be made of carbon steel, stainless steel, copper) and extruded by machine to form fins. The base of the fins is closely attached to the outer wall of the tube. High heat transfer coefficient and excellent heat transfer performance. Rolled finned tube fins are smooth, burr-free, wrinkle-free, beautiful and bright, and easy to clean. When used as components of air heaters and surface coolers, it is easy to remove condensed water on the surface, and it is not easy to dust and condense in drying heating and other occasions. The fins of the rolled finned tube are cross-sectional and trapezoidal, so the fins have high strength and expand the heat dissipation surface, so that the material can be used.

The extruded finned tube is made of iron or copper and aluminum tubes and then rolled out of fins. It has tight bonding, small thermal resistance, good heat transfer performance, high strength, small flow loss, and strong corrosion resistance. It is not easy to deform under thermal conditions, and has the advantages of long working life and so on.

Extruded finned tubes

The overall extruded fins are smooth and burr-free, easy to clean, and it is easy to condense water on the surface of the fins during wet cooling in heating and air conditioning projects. In drying heating and other heat exchange occasions, the surface is anodized, and the color is beautiful and generous. , and can effectively prevent surface corrosion.

Aluminum extruded finned tube is integrally rolled from aluminum tube, with no contact thermal resistance, high strength, thermal shock and mechanical shock, good thermal expansion performance, and a considerable extended heat exchange surface, made of this finned tube The heat exchanger is suitable for string or wound heat exchangers.

According to the needs of users, various specifications of steel-aluminum composite finned tubes can be processed.
