Our new six row Twisted Fin liquid to liquid heat exchangers are now available. These are built to your specification with a range of water hose spigots and oil unions. This allows simple integration into your existing water and oil systems.
The compact and robust design give superior heat rejection figures compared to heat exchangers of the same size or weight.
These can be fitted virtually anywhere on the car without the need to be in a cold air stream.
Prices start from £325 +Vat.
We are working on increasing our twisted fin design to include air to liquid coolers and also produce a larger range of sizes.

New Extruded Tube with Twisted Fins promises great advantages in heat exchanger design.

Multi-channel extruded aluminium tube has been around for many years and has widespread uses in heat exchanger construction. Efficiency is however limited due to the need to bond an extended surface to the tube in the form of thin convoluted fin.
Brise Fabrications have developed a new manufacturing technique that will reduce the manufacturing cost and improve the efficiency of currently available products.
In addition to the multi-channel internal section of the tube, the Brise Twisted-Fin tube is extruded with continuous external fins running laterally along its length. In a post-extrusion forming operation, the lateral fins are twisted and sheared into an array of fins segments. These segments allow air or liquid to flow across the tube surface at right angles to the flow of Air or liquid in the internal channels. The segments are angled to promote a turbulent flow which enhances heat transfer.
Being formed from the parent material of the tube there is no thermal barrier caused by bonding or brazing of the extended surface and manufacturing costs are reduced. When the tubes are assembledinto a complete heat exchanger assembly the external fin arrays interlock to produce a very complex and thermally efficient path for fluids whilst retaining a very low pressure drop. Interlocking of the fins also reduces the physical size of the assembly and maximises the tube density. The lightweight fully welded final assembly can cope with very high pressures and temperatures.
The Brise heat exchanger is being used in Competition Cars, to give improved performance in Oil/Water heat exchangers ( below ), Air/Water Turbo charge air coolers ( right ), and Air/Oil coolers. Many Industrial applications may also benefit from the new technique, and Brise Fabrications are currently looking for partners to develop new market opportunities for their patented* process.
