Abstract
A heat exchanger for a turbine is provided wherein the heat exchanger comprises a heat transfer cell comprising a sheet of material having two opposed ends and two opposed sides. In addition, a plurality of concavities are disposed on a surface portion of the sheet of material so as to cause hydrodynamic interactions and affect a heat transfer rate of the turbine between a fluid and the concavities when the fluid is disposed over the concavities.
Claims29
A heat exchanger for receiving exhaust fluid from a turbine and combustion fluid from a compressor, the heat exchanger comprising:
- a heat transfer cell comprising a sheet of material having two opposed ends and two opposed sides;
- and
- a plurality of concavities disposed on a surface portion of said material so as to cause hydrodynamic interactions and affect a heat transfer rate of said turbine between said exhaust fluid from said turbine and said combustion fluid from said compressor and said concavities when said exhaust fluid and said combustion fluid are disposed over said concavities.
A heat exchanger for a turbine comprising:
- a heat transfer cell comprising a sheet of material having two opposed ends and two opposed sides;
- and
- a plurality of concavities disposed on a surface portion of said material so as to cause hydrodynamic interactions and affect a heat transfer rate of said turbine between a fluid and said concavities when said fluid is disposed over said concavities, wherein at least one plate is coupled to at least one of said heat transfer cells so as to define a plurality of chambers between said plate and said heat transfer cells.
