A finned tube is a heat exchange element with a series of fins tightly bonded (through welding, expansion, extrusion, etc.) to the outer or inner surface of a base tube (usually a round tube). Its core purpose and greatest advantage is to significantly increase the heat transfer surface area, thereby […]

When purchasing extruded fin tubes, it’s important to consider multiple factors, including material, craftsmanship, operating environment, and after-sales service, to ensure you’re purchasing a suitable and durable product. Extruded Fin Tube Inspection Appearance and Structural Inspection Visually inspect the fins for flatness, deformation, collapse, or damage, and for cracks or

What is an air conditioner evaporator? Air conditioner evaporators are refrigeration devices. Air conditioner evaporators are key components in refrigeration systems. They achieve cooling by absorbing heat and vaporizing low-temperature, low-pressure liquid refrigerant after throttling through the expansion valve. Their structure primarily consists of the evaporator core, expansion valve, and

Finned tubes are heat transfer enhancement components that increase the heat transfer area by adding fins to the base tube surface. They are widely used in industries such as petrochemicals, power generation, metallurgy, and refrigeration. Finned tubes can be divided into various types based on fin shape, processing technology, and

What are low-fin tubes? Low-fin tubes are heat exchange components in which fins of a specific height, pitch, and thickness are machined onto the outer surface of a plain tube through a mechanical rolling process. They are primarily manufactured using a three-roll cross-rolling method. The base tube and outer fins
