Abstract
The present disclosure includes geometry of a two-fluid heat exchanger to provide higher energy efficiency than conventional heat exchangers. The geometry is based upon sequential branching of nearly circular passages in sets, followed by some deformation and twisting of the sequential branches that intermingle flow passages of one fluid with flow passages of another fluid. The flow passages gradually vary in dimension from larger branching at fluid entrance and exit to smaller branching in the middle section of the heat exchanger. The heat exchanger is substantially symmetric, with the sequential branching in the first half being mirrored as serial regrouping in the second half. The present disclosure also provides stacking methods and layered manufacturing methods for fabricating the three-dimensional geometry of the heat exchanger.
