Delkang Refrigeration Equipment from Xiangshui County has produced high-performance cooling fins since 2006. These fins are core parts for heat exchange, offering exceptional conductivity for industrial and commercial systems.
Copper Materials Give High Conductivity
Tubes: TP2 phosphorus deoxidized copper, purity ≥99.9%, heat transfer ≥380 W/(m·K). Fins: H62 brass, or T2 copper for high-precision needs. Tube diameters: φ9.52 mm, φ12.7 mm, φ15.88 mm; wall thickness: 0.3 mm, 0.45 mm, 0.6 mm.
Flexible Fin Setup
Fin thickness: 0.18 mm; spacing: 1.8, 2.5, or 3.5 mm. Tube rows: 2, 4, 6, 8. Expansion or welding used, fit rate ≥98%. Design pressure: 1.6 MPa (regular), 2.5 MPa (high pressure). Surface passivation standard; tin plating (≥10 μm) for corrosive conditions. OEM and ODM services supported.
