Abstract:
1. A heat exchanger for exchanging heat between a primary fluid and a secondary fluid, comprising: a. a vessel, including a primary fluid inlet, a primary fluid outlet, a secondary fluid inlet, and a secondary fluid outlet; b. a plurality of secondary flow channels, with each of said secondary flow channels being formed by a pair of plates having an inlet fluidly connected to said secondary fluid inlet and an outlet fluidly connected to said secondary fluid outlet; c. said plurality of secondary flow channels being fluidly connected in parallel; d. each of said plates having an outward facing primary fluid side; and e. a spray manifold fluidly connected to said primary fluid inlet, said spray manifold having a plurality of spray nozzles directed toward said outward facing primary fluid sides of said secondary flow channels, said spray nozzles directing a spray of said primary fluid against said outward facing primary fluid side of one of said secondary flow channels; a plurality of spray manifolds located in between said pairs of plates forming said secondary flow channels; wherein each of said spray manifolds is bound by a pair of mated spray plates, with each of said spray plates having an inward facing liquid primary fluid side and an outward facing evaporating primary fluid side; and wherein said spray plates and said plates are bonded together.
