Abstract: A fluid channel formed with generally triangular-shaped performance enhancement features is disclosed. The fluid channels may be incorporated into heat exchanger or humidifier devices, the performance enhancement features generally having heat transfer and/or mass transfer performance enhancement applications. The heat transfer or mass transfer enhancement features are formed along the inner surfaces of the fluid flow passages of either the heat exchanger or humidifier plates and generally have sharp leading edges that create vortices in the fluid flowing through the passages. The heat or mass transfer enhancements protrude out of the inner surface of the fluid flow passages while leaving the outer surface of the fluid channel free of perforations. Alternatively, heat or mass transfer enhancements may be formed on separate inserts that are affixed to the inner surface of the fluid flow passages.

Abstract: A heat exchanger containing a plurality of spaced-apart plate pairs, where each plate pair defines a flow passage for the flow of a first fluid. In addition, one or more fins are thermally coupled and sandwiched by the spaced-apart plate pairs for flow of a second fluid. And, a fluid manifold that is fluidly coupled to the spaced-apart plate pairs at a manifold end of the spaced-apart plate pairs is provided. Further, a tab that extends from a flange end of a first plate of the first plate pair and in contact with a second tab extending from a flange end of a second plate of a second plate pair for providing a fluid flow blocker. Also, provided is a heat exchanger assembly containing a housing and the heat exchanger described herein.

Abstract: A heat exchanger having a plurality of spaced-apart plate pairs, where each plate pair defines a flow passage for the flow of a first fluid. One or more fins are thermally coupled and sandwiched by the spaced-apart plate pairs for flow of a second fluid. A fluid manifold being fluidly coupled to the flow passages of the spaced-apart plate pairs is also provided. The heat exchanger has a front face and side faces defined by at least the plurality of spaced-apart plate pairs and the one or more fins. And, a bypass seal complementary to the front face or one of the side faces and engagingly coupled to the front face or one of the side faces for blocking a gap between the heat exchanger and a housing for receiving the heat exchanger. Also disclosed is a heat exchanger assembly having the heat exchanger disclosed.
