A heat exchanger system is described for thermochemical storage and release. The system comprises a thermal exchange circuit with a heat exchanger fluid, the circuit further in thermal connection with a thermochemical module. The thermochemical module comprises a thermochemical material that stores and releases heat by a thermochemical exchange process under release or binding of a sorbate. The thermochemical module comprises a compartment structure that compartments the thermochemical material and further comprises a channel structure. This provides an exchange of the sorbate: and the thermochemical material via the channel structure to the compartment structure.

In an embodiment, a heat exchanger includes a monolithic body that includes a first substrate, a second substrate, a third substrate, and a plurality of partial height fins. The second substrate is arranged parallel to and spaced from the first substrate, thereby defining a first fluid flow path. The third substrate is arranged parallel to and spaced from the second substrate opposite the first substrate, thereby defining a second fluid flow path. The plurality of partial height fins extend from one of the second substrate and the third substrate toward the other of the second substrate or the third substrate, wherein a terminal edge of each partial height fin is at least partially spaced from the other of the second substrate or the third substrate.

A heat exchanger, the heat exchanger including flat tubes and fins. The flat tubes are provided at intervals along the thickness direction of the flat tubes. The flat tubes are internally provided with fluid channels extending along the longitudinal direction of the flat tubes. The fins are provided between adjacent flat tubes. A plurality of fins between adjacent flat tubes are provided at intervals along the transverse direction of the flat tubes. Each fin extends along the longitudinal direction of the flat tubes. Ventilation windows are provided on the fins.

A radiator which rejects heat to its surrounding environment through radiation, comprising layers of thermally conductive material in a tapered geometry. As well, a radiator which incorporates structural support to maintain rigidity in the out-of-plane directions for its thermally conductive layers. The radiator is used by incorporating a source of heat to the layers, having a lower temperature in the surrounding environment, and structurally attaching to an assigned location.
