    摘要： A method of manufacturing a heat transport device includes a flat plate working process, a first joining process, a plastic working process, and a second joining process. In the first plate working process, a processed flat plate Q including recesses is obtained. In the first joining process, a flat plate R and the processed flat plate Q are joined to obtain a first flow passage plate including a first set of flow passages. In the plastic working process, the first set of flow passages are deformed to form recesses and obtain a second flow passage plate. In the second joining process, multiple second flow passage plates are stacked on top of each other and joined to form a second set of flow passages which is not parallel to the first set of flow passages.

    摘要： A plate for a heat exchanger between a first medium and a second medium, the plate being associated with a main plane of extension and a main longitudinal direction and including a first heat transfer surface, extending substantially in parallel to the main plane and arranged to be in contact with the first medium, generally flowing along the first surface in a first flow direction; and a second heat transfer surface, extending substantially in parallel to the main plane and arranged to be in contact with the second medium, generally flowing along the second surface in a second flow direction. The first surface includes protruding ridges defining at least two parallel and open-ended channels extending in the first flow direction. The second surface includes a plurality of protruding dimples arranged in the channels between neighbouring respective pairs of the ridges.

    摘要： Plate (710) for a heat exchanger between a first medium and a second medium, the plate being associated with a main plane (P) of extension and a height direction (H) perpendicular to said main plane, and comprising a first heat transfer surface (714) on a first side (713) of the plate, arranged to be in contact with the first medium flowing along said first side; a second heat transfer surface (716) on a second side (715) of the plate, arranged to be in contact with the second medium flowing along said second side; a plurality of indentations (720,730,740) in the plate, formed by the material of the plate bulging out locally in the said plate height direction, of which a plurality are bridge-shaped indentations (730) comprising two respective through-holes (732a) in the plate, as well as a respective bridge part (734) forming a passage (706,706′) between the said through-holes, and wherein the passage has a general direction being substantially parallel to a general flow direction (D) of the second medium past the bridge-shaped indentation in question. The invention is characterised in that, for at least a plurality of the said bridge-shaped indentations, the shape of the respective bridge part, in a cross-section taken perpendicularly to both the main plane and to the said general direction of the passage in question, comprises a local minimum (737), so that the height of the bridge part, in said cross-section, first increases, then decreases to the said local minimum, and then again increases.

    摘要： A plate-stacked heat exchanger is proposed which exchanges heat with high heat exchange efficiency in flow paths each including an internal space bulging outward between two heat transfer plates. A flow path forming portion includes a plurality of flow path bulging portions that bulges outward of a heat exchanger plate and forms heat exchange flow paths of a first heating medium therein, and a header portion includes a communication hole communicating with the header portion of an adjacent heat exchanger plate, and a flow path forming portion-side expanded portion expanding from the communication hole toward the flow path forming portion, and the flow path forming portion-side expanded portion communicates with the plurality of heat exchange flow paths. Consequently, heat can be exchanged in a greater width. Therefore, a high heat exchange rate can be obtained.

    摘要： A heat transfer plate and a heat exchanger comprising a plurality of such heat transfer plates are provided. The heat transfer plate comprises a heat transfer pattern of alternately arranged ridges and valleys. First and second adjacent ridges extend obliquely in relation to a longitudinal centre axis of the plate and comprise a first top portion and a second top portion, respectively, and first and second adjacent valleys extend obliquely in relation to the longitudinal centre axis and comprise a first bottom portion and a second bottom portion, respectively. The first bottom portion of the first valley is connected to the first top portion of the first ridge by a first flank and to the second top portion of the second ridge by a second flank, and the second top portion of the second ridge is connected to the second bottom portion of the second valley by a third flank.

    摘要： A tube body for a heat exchanger may include an outer structure composed of a band material. The outer structure may include two mutually opposite wide sides and two mutually opposite narrow sides delimiting an outer structure interior space. The tube body may further include an inner structure integrally arranged on the outer structure and composed of the band material. The inner structure may be arranged in the outer structure interior space and divide the outer structure interior space into at least two fluid ducts fluidically separated from one another through which a fluid is flowable. The band material may have a material thickness and, at least in certain portions, a material thickness of a portion of the band material defining the inner structure may be less than a material thickness of a portion of the band material defining the outer structure.
