CSF BMW M3 Race Triple Pass Radiator (E90)
CSF manufactures the most advanced and efficient radiator cores in the industry by using innovative tube and fin technologies with industry leading testing methods to maximise airflow and heat dissipation. These techniques allow CSF to stay ahead of the pack when it comes to radiator technology!
- “B-Tube” technology – Unlike a regular oval shape “O” type radiator tube, CSF uses a specially engineered tube in a shape of a “B”. These “B-tubes” are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminium material (better cooling efficiency) because this design is actually stronger than normal “O” shape tubes that are welded.
- The design (inlet in the middle of tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes. You get the efficiency of 2 smaller tubes vs. 1 large tube with it the same space criteria. With “B-tubes” you are able to get “dual liquid laminar flow.”
- High Efficiency Multi Louvered Fin – CSF uses ultra efficient multi louvred fins that are carefully and precisely aligned to maximise airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.
