Abstract
A pressure sealed, laminated fluid-to-fluid heat exchanger is disclosed herein. The heat exchanger includes a laminated stack of alternating orifice and spacer plates with the orientation of the spacer plates relative to the orifice plates defining first and second fluid paths. A low pressure fluid conduit is provided for connecting a low pressure fluid supply to one of the fluid paths. A high pressure shell houses the stack and includes inlet and outlet ports for a high pressure fluid. The high pressure fluid enters the shells and traverses the other fluid path and also places the stack under compression to aid the bonds between the spacer plates and the orifice plates.
