A porous heat exchanger including a single piece core extending axially is provided. The core defines a first air inlet and a first air outlet for a first fluid, a second air inlet and a second air outlet for a second fluid. The first/second fluid flows into the core from the first/second air inlet through a first/second fluid channel and flows out of the core through the first/second air outlet. The core includes solid material sheets and porous material sheets disposed alternately with the solid material sheets so each porous material sheet has an adjacent solid material sheet on each side defining one of the first fluid channel for a flow of the first fluid or the second fluid channel for a flow of the second fluid. Heat transfer occurs between the first fluid in the first fluid channel and the second fluid in the second fluid channel.

A system and a method for heating source fluid, comprising: a turbine-electric generator transport comprising: an inlet plenum and an exhaust collector; a turbine connected to the inlet plenum and the exhaust collector; and an electric-generator coupled to the turbine; an exhaust heat recovery transport comprising: a combustion air connection coupled to the inlet plenum; an exhaust air connection coupled to the exhaust collector; a heat transfer assembly coupled to the exhaust air connection; and a fluid system coupled to the heat transfer assembly; an inlet and exhaust transport comprising: an air inlet filter housing coupled to the combustion air connection; and an exhaust stack coupled to the exhaust air connection.

An axial flow baffle for a shell and tube heat exchanger includes a substantially planar body configured for transverse arrangement in a longitudinally elongated shell of the shell and tube heat exchanger, a plurality of axial flow tube apertures each comprising a central tube hole configured to receive a tube of the heat exchanger, and an array of peripheral primary flow holes circumferentially spaced apart around the tube hole. The primary flow holes each interrupt the central tube hole and formed a radially inward projecting tube support protrusions between the primary flow holes which engage a single tube. Each primary flow hole has a non-polygonal configuration, which may be semicircular in some embodiments. The primary flow holes create axial flow around the periphery of the tubes through the baffles. In another aspect, a hybrid cross-flow baffle includes a combination of axial flow tube apertures and circular tube support holes.

A heat dissipator includes a plate-shaped base portion extending in a first direction along a refrigerant flowing direction and in a second direction orthogonal to the first direction and has a thickness in a third direction orthogonal to the first direction and the second direction, and fin groups including fins arranged in the second direction, protruding from the base portion to one side in the third direction and extending in the first direction. One of the fins includes a spoiler with an opposing surface that opposes one side in the first direction that is a downstream side in the refrigerant flowing direction. A number of the spoilers included in each of the fins in a same second direction position in the fin groups increases toward the one side in the first direction.
