UFI Filters, a leading company in the fields of filtration and thermal management as well as hydrogen filtration, is equipping the Premium Platform Electric (PPE) from Audi and Porsche with the transmission oil cooling system, thereby consolidating its expertise in the field of electromobility.
Due to its modularity, the PPE platform developed by these brands is intended for a large number of BEV models in the premium and luxury segment. Each new mid-range model such as the Porsche Macan EV, the Audi Q6 e-tron, the A6 e-tron Avant and the A6 e-tron Sportback, including the RS versions, will be equipped with a UFI cooler on the gearboxes of the electric motors on the front and rear axles, ensuring outstanding performance characteristics.
UFI manufactures its thermal management systems at its modern production plant in Opole, Poland. The use of the aluminum vacuum brazing process results in a robust and clean product. The company’s coolers make an important contribution to keeping the transmission oil temperature within the optimum operating values.
The front radiator consists of aluminum plates with 11 layers for the oil and 10 layers for the coolant, while the rear radiator consists of 14 layers for the oil and 13 layers for the coolant. The heat exchangers are designed according to the cross-counterflow principle. In this configuration, the oil and coolant flow in opposite directions, with the fluids (oil and coolant) crossing their flows in alternating layers. This arrangement extends the contact time of the fluids for heat transfer. This improves the cooling capacity and therefore also the efficiency of the radiator. Giorgio Girondi, Chairman of the UFI Filters Group, comments: “Technological innovation and forward thinking are in UFI’s DNA, as evidenced by this electromobility project. We are delighted with the confidence that the VW Group has placed in our thermal management systems. This is further confirmation of the performance level of UFI components.”
