MULTI VANE TECHNOLOGY MVT stands for Multi Vane Technology. This revolutionary design enhances the efficiency of an intercooler by using vanes in the end tank to redirect air across a much larger area of an intercooler core. This leads to reduced intake temperatures and increased engine performance. But exactly how do we design our award-winning MVT intercoolers? 3D Scanning We begin by scanning all aspects of the OEM intercooler and the front of the car. These scans allow us to accurately measure how much space is available for a new intercooler. The scanner builds three-dimensional computer visuals that can be rotated and viewed from any angle. Computer-Aided Design (CAD) Once we have completed the scans, we convert the files into a format compatible with our state-of-the-art CAD software. The scans are used as a base to build our own intercooler models. We do this to ensure accurate fitment, by matching OEM end tank positions and mounting points. End tanks are individually designed to optimize size, flow and efficiency. The resulting model is overlaid onto the 3D scans we gathered earlier to double-check for clearance around the front of the car. Computational Fluid Dynamics (CFD) With the model built, we use CFD analysis to simulate airflow through the intercooler. We do this to check an intercooler’s efficiency before we start designing our vanes (MVT). With the aid of CFD simulations, we can design our vanes to maximize cooling efficiency, utilizing as much of the core’s surface area as possible. We are also able to see how the smallest alterations can affect this. We repeat this process until each design meets our high standards. CFD analysis shows us the disadvantages of commonly used angled end tanks. The sharp angles result in the flow of air being restricted. This would ultimately result in an increased pressure drop across the intercooler and the turbo would be required to work harder to produce boost. Direnza engineers instead use cast end tanks, which offer exceptional airflow characteristics. This is enhanced further with MVT, which distributes air evenly across the core, lowering intake temperatures and reducing pressure drop. 3D Printing & Test Fitting After we have completed our CAD work, the model is printed in full scale on one of our 3D printers. An intercooler print generally takes a few days to complete. We can use this to test fitment on the car, noting down any adjustments required. Once happy with the design, fitment and performance simulations a pre-production example can be manufactured and go through another stage of testing. This stage of testing will include fitment and real-world performance.
