I. Structure and Manufacturing Process of G-Type Finned Tubes

The fins of G-type finned tubes are bonded to the base tube using an embedded process:

The fin strips are embedded into pre-machined grooves in the base tube, and then a “groove filling” process ensures a firm fit between the fins and the base tube, achieving a tight connection.

The manufacturing process is a continuous operation (groove machining, fin embedding, and groove filling are performed simultaneously), resulting in strong process stability and ensuring the bonding strength between the fins and the base tube, thereby improving heat transfer reliability.

II. Heat Transfer Performance and Advantages of G-Type Finned Tubes

The heat transfer advantages of G-type finned tubes stem from their structural design and process assurance:

The robust bond between the fins and the base tube significantly reduces the thermal resistance at the heat transfer interface, resulting in a substantial improvement in heat transfer efficiency;

Suitable for high-temperature conditions (such as high-temperature flue gas and high-temperature fluid heat exchange), while also exhibiting good adaptability to relatively low-corrosion environments, broadening the temperature and corrosivity boundaries of their application scenarios.

III. Typical Application Scenarios of G-Type Finned Tubes

G-type finned tubes play a crucial role in multiple industrial fields, with typical scenarios including:

Air coolers: Utilizing fins to expand the heat exchange area for efficient cooling of high-temperature process fluids;

Radiators: Achieving efficient heat exchange between fluids and air to meet equipment heat dissipation requirements;

Industrial applications: Widely used in the power industry (e.g., power plant heat exchange systems), chemical industry (e.g., reactor cooling/heating), oil refining (e.g., crude oil preheating), chemical process plants, rubber factories, etc., providing efficient heat transfer support for various heat exchange equipment.

Through structural innovation and process optimization of “embedded fins + base tube”, G-type finned tubes have achieved a balance between heat transfer efficiency and environmental adaptability, becoming an indispensable high-efficiency component in industrial heat exchange systems.
