A recuperator including a number of neighbouring hexagonal sheets which are connected to each other. Flow passages are formed between neighbouring sheets. Each of the sheets, at its periphery, is at least partially surrounded by and connected to an associated connecting body. Neighbouring connecting bodies are connected to each other at at least a part of the periphery of the associated sheets and together form the wall of a housing. Passage openings are provided in the wall which are connected to the flow passages for allowing air into the flow passages via the passage openings. Neighbouring connecting bodies are provided with protruding parts and with recesses respectively on sides facing each other, wherein the forms of the protruding parts and of the recesses adjoin each other in order to connect the connecting bodies to each other by a press fit. Methods for producing a connecting body and for producing a recuperator.

The minimal surface structure separating a first volume and a second volume within the enclosure. The first inlet and the first outlet being in fluid communication with the first volume, and the second inlet and a second outlet being in fluid communication with the second volume. The first and second volumes separated from mixing with each other.

A heat exchanger system comprises a first heat exchanger, a second heat exchanger, a mixer, and a third heat exchanger. A first working fluid flow path connects the first working fluid outlet port and the first mixer inlet port, a second working fluid flow path connects the second working fluid outlet port and the second mixer inlet port, and a third working fluid flow path connects the mixer outlet and the third inlet port.

A system and method for thermally exchanging heat between waste air being expelled from a poultry barn and fresh outside/outdoor ambient air being introduced into the poultry barn.

A heat exchange assembly in an air to air heat exchanger includes an arrangement, construction, and/or configuration of a combination of latent heat exchangers and sensible heat exchangers. The heat exchange assembly can minimize footprint required for the air to air heat exchanger, e.g. air handler, by avoiding the need for block offs and plenums, can support direct mounting of a bypass damper(s), can provide acceptable pressure drop ratings and provide good heat exchange efficiency and energy recovery performance. The arrangement and configuration of the sensible heat exchangers and latent heat exchangers of the heat exchange assembly have condensate management for example to provide frost protection.

A heat exchanger includes a prism-shaped heat exchange element, a plurality of frame members mounted to sides of the element in a one-to-one relationship, the sides extending along an axial direction of the heat exchange element, and cover members each covering an end face of the element, the end face being perpendicular to the axial direction of the heat exchange element. The frame members are connected to each of the cover members. Gaps for allowing movement of each of the frame members along a direction perpendicular to the axial direction of the heat exchange element are provided at each connecting portion at which the frame members are connected to the cover member. Thus, it is possible to move the frame members along with deformation of the heat exchange element.

The present invention discloses a high-temperature fluid transporting pipeline with a heat exchange apparatus installed therein, a suitable heat exchange apparatus and a heat exchange method, wherein heat contained in a high-temperature fluid can be recovered during the transportation thereof. The heat exchange apparatus comprises a heat exchange body inserted into the high-temperature fluid transporting pipeline, and a heat-receiving fluid coil installed therein. The method of heat exchange is that the high-temperature fluid heats an auxiliary fluid in a heat exchange cavity via a heat exchange panel of the heat exchange body in contact therewith, and the heated auxiliary fluid then conducts the heat to a heat-receiving fluid in the heat-receiving fluid coil. As an example, the high-temperature fluid is flue gas generated by combustion, the heat exchange apparatus of the present invention is inserted into a flue gas transporting pipeline, the auxiliary fluid is an inert gas such as air, and the air heated indirectly by the high-temperature flue gas conducts heat to fuel and/or oxygen-enriched gas (serving as an oxidant/combustion aid) flowing in the heat-receiving fluid coil.
