A thermal regenerator apparatus is disclosed including a regenerator medium having a plurality of flow passages extending between first and second ports, the flow passages facilitating back and forth fluid flow in a generally transverse direction between the first and second ports while the medium alternatively receives thermal energy from and delivers thermal energy to the fluid. The regenerator medium includes a plurality of overlying foils, each foil having a plurality of channels extending through the foil, the channels having beveled sidewalls. The channels have a width and spacing in the transverse direction and channels in each adjacent overlying foil are transversely offset such that each channel spans between and is in fluid communication with a pair of channels in the adjacent foils and the beveled sidewalls of the channels redirect fluid flow between channels in adjacent foils to form the flow passages. The channels are elongated along the foil in a longitudinal direction orthogonal to the transverse direction and divided by foil bridges extending transversely, the foil bridges being sized to reduce thermal conduction through the medium in the transverse direction.

An apparatus for exchanging heat with a fluid includes a heat exchanger having first and second opposing surfaces and a plurality of flow passages permitting axial fluid flow between the surfaces. A manifold having an interface surface is in thermal contact with the first surface and includes a thermally conductive body for conducting heat in an axial direction between the interface surface and a heat transmitting surface. A plurality of feed passages extend through the thermally conductive body in a transverse direction, the passages having an inlet for receiving or discharging fluid. A plurality of distribution passages have ends in fluid communication with at least one of the feed passages and openings distributed over the interface surface. The distribution passages are configured to cause a change in fluid flow direction between a transversely directed flow in the feed passages and an axially directed flow at the openings.
