Abstract
A heat exchanger element has upper and lower walls defining upper and lower flow surfaces of a flow path; turbulators on the upper and lower flow surfaces; and a fin pack between the upper and lower surfaces, the fin pack having alternating angled walls extending between the upper and lower surfaces to define triangular flow passages in the flow path between the upper and lower walls. A heat exchanger stack can have multiple layers of the heat exchanger element, and a method for making the heat exchanger is disclosed. The structure produces advantageous flow characteristics.
