Abstract
A heat exchanger has at least one plate pair comprising first and second plates with a fluid flow passage defined between the first plate and second plates. The inlet opening and the outlet opening in each plate pair are proximate to a first end and an elongate flow barrier separates the fluid flow passage into inlet and outlet portions, wherein a gap through and the flow barrier is provided proximate to the second end of each plate pair. A flow obstruction is located in the gap of each plate pair, the flow obstruction having first and second arcuate sides and being spaced from the terminal end of the flow barrier. The flow obstruction is substantially crescent-shaped, such that a middle portion of the flow obstruction is wider than the opposed ends.
