Heat transfer augmentation in a compact heat exchanger pedestral array

摘要

A compact heat exchanger pedestal array for augmenting heat transfer in a machine is disclosed. The compact heat exchanger pedestal array includes a wall (46) having first and second surface (48, 50). The first surface (48) faces a heated flow path and the second surface (50) partially forms a flow path for cooling fluid. A plurality of pedestals (40) extend from the second surface (50) of the wall (46). At least one turbulator strip (42) extends between adjacent pedestals (40). The turbulator strips (42) and pedestals (40) are operable for mixing the cooling fluid to increase heat transfer from the wall to the cooling fluid.
