Disclosed is a heat exchanger, including a plurality of adjacent sheets. An upper surface of each sheet is provided with a plurality of raised peak lines that are arranged in parallel and spaced rows and raised upward, and a lower surface of each sheet is provided with a plurality of raised contour lines that are arranged in parallel and spaced rows and raised downward. A first flow channel and a second flow channel are formed between adjacent three sheets.

A convection is formed by the fluid flowing through the first flow channel and the second flow channel. The present disclosure can improve heat exchange efficiency and be easy to industrialize.

A heat exchanger apparatus and a method of operating the heat exchanger apparatus include a convergent interface separating two counterflows, and at least two concentric conduits including an inner conduit and an outer conduit, wherein the outer conduit comprises an outer conduit radius that is maintained as invariant, and the inner conduit comprises an inner conduit radius that is adjustable to form the convergent interface separating the two counterflows, wherein heat transfer with respect to the two counterflows occurs at the convergent interface.

A heat exchanger comprising a plurality of A channels in a heat exchanger matrix running in a first direction wherein each A channel is formed along its length as a waveform with an identical wavelength, channel width, wave angle, and wall thickness. Adjacent A channels running in an orthogonal direction are 180 degrees out of phase. The plurality of A channels form the plurality of B channels running in a cross-flow direction with the outer walls of the A channels. The B channels exist as the negative space between adjacent 180 degree out of phase A channels.

A crossflow heat exchanger includes an outer housing, an inlet that receives a hot fluid to be cooled and a monolithic manifold includes a central receiving reservoir and one or more outer reservoirs. The fluid received at the inlet passing into the central receiving reservoir. The exchanger also includes an outlet connected to the one or more outer reservoirs and tubes disposed within the outer housing that connect the central receiving reservoir and the one or more outer reservoirs. The monolithic manifold includes a gap formed between the central receiving reservoir and one or more outer reservoirs.

A counter-current cross-flow heat exchanger for heating a first gas and cooling a second gas, includes modules in fluid communication with one another, each module being positioned on a plane, the planes mutually overlapping. Conduits allow entry and exit of the first and second gases into and out of the exchanger. Each module has heat exchange plates, with heating and cooling faces. The plates are orthogonal to the module plane and parallel to define alternating heating and cooling spaces. The first gas crosses each heating space with a direction substantially parallel to the plane of each module and the second gas crosses each cooling space with a direction substantially orthogonal to the plane of each module. The cooling spaces between adjacent modules are in direct fluid communication. The heating spaces between adjacent modules are in fluid communication with one another by conduits/conveyors, creating a serpentine path.

A heat exchanger includes a first layer, a second layer, and a third layer. The first layer includes a first width W.sub.1 extending in a first direction and a first length L.sub.1 extending in a second direction. The second layer includes a second length L.sub.2 extending in the first direction and a second width W.sub.2 extending in the second direction. The third layer includes a third width W.sub.3 extending in the first direction and a third length L.sub.3 extending in a second direction. The second layer is between the first layer and the third layer. The first length L.sub.1 of the first layer and the third length L.sub.3 of the third layer both extend further in the second direction than the second width W.sub.2 of the second layer. The first layer and the third layer include an overhang.

The present invention relates to a heat exchanger (2) having a jacket (10) through which a first medium (A) can flow and which has at least one first inlet (11) and at least one first outlet (12), at least one tube (30) through which a second medium (B) can flow, the tube (30) being guided through the jacket (10) and having at least one second inlet (31) and at least one second outlet (32), wherein a deflection segment (50) or a plurality of deflection segments (50) are arranged in a row in a longitudinal axis (X) in the jacket (10), wherein the deflection segment (50) is formed from at least two partial sections (51, 52), which are arranged so as to overlap and cross, in areas, transverse to the longitudinal axis (X).
