The CSF Universal Half Radiator represents a pinnacle of engineering excellence tailored specifically for the 1992-2000 Honda Civic platform, as well as Mitsubishi Evolution models 7, 8, and 9. This radiator is designed to deliver superior cooling performance while maintaining a compact form factor, making it an ideal upgrade for enthusiasts and professionals seeking reliability and efficiency in demanding conditions.
At the core of this radiator’s innovation lies the exclusive B-Tube Technology, a significant advancement over conventional oval-shaped "O" tubes typically found in standard radiators. Unlike traditional tubes that rely on welding, CSF’s B-tubes are meticulously formed and seam-brazed, resulting in a structure that is not only stronger but also lighter due to the use of thinner aluminum. This design enhances heat transfer by approximately 15% compared to regular tubes, effectively doubling the cooling efficiency within the same spatial constraints. The unique inlet positioned in the middle of the tube facilitates dual liquid laminar flow, optimizing thermal dissipation and ensuring consistent engine temperature regulation.
Complementing the B-tube core is a 2-row, 42mm dual-core construction equipped with ultra-efficient multi-louvered fins. These fins, precisely engineered with a 6.5mm height and aligned to maximize airflow, significantly increase the surface area contact, thereby improving heat rejection. Each fin configuration is rigorously tested in CSF’s wind-tunnel laboratory to guarantee optimal performance under various operating conditions.
