SZL (B) type finned tube radiator is composed of seamless steel pipe with a diameter of 25 × 2.5mm as the base tube, aluminum hole finned tube with an outer diameter of 57mm, a root diameter of 26.5mm, and a spacing of 2.8mm. Good heat dissipation performance, reliable use, corrosion resistance, smoothness, and aesthetics. Applied in industries such as dairy, beer, food, starch, chemical, papermaking, machinery, medicine, air conditioning, printing and dyeing.
The SZL (B) finned tube radiator requires a higher heat transfer coefficient K value in terms of thermal performance during operation, which indicates better heat dissipation performance. To increase the heat dissipation capacity of the radiator and increase the heat transfer coefficient of the finned tube radiator, methods such as increasing the outer wall heat dissipation area, improving the air flow velocity around the finned tube radiator, and increasing the outward radiation intensity of the radiator can be used.
The process and installation of SZL (B) finned tube radiator mainly require its equipment to have good mechanical strength and pressure bearing capacity. Its structural form should be easy to combine to form the required heat dissipation area, and its structural size should be small, occupying less room area and space. The production process of finned tube radiator should meet the requirements of large-scale production.
