Problems solved by technology

[0004] If the plate is made into a non-circular shape such as an ellipse, the lateral dimension will become larger, so it is difficult for the heat exchange fluid (especially the sensible heat fluid for sensible heat exchange) to spread throughout the lateral end side area, and the heat transfer area will be reduced. Potential to reduce heat exchange performance

Embodiment Construction

[0087] Several embodiments of the present invention will be described below with reference to the drawings. However, as the size, material, shape, and relative configuration of the constituent member shown in the figures or the like, and the like are not intended to limit the scope of the present invention.

[0088] For example, "in a certain direction", "along a direction", "parallel", "orthogonal", "center", "concentric" or "coaxial" or the like to represent the relative or absolute configuration Expression not only indicates that strict configuration, but also indicates a tolerance or an angle of the degree of the same function, the distance is relatively shifted.

[0089] For example, "the same", "the same", and "homogeneous" means that the expression of the equivalent state not only means a strict equivalent state, but also a state in which a tolerance or a difference in the same function can be obtained.

[0090] For example, the expression of the shape of the quadrilateral ...

Abstract

An embodiment of a plate stacking body includes: a plurality of plates that are stacked with concavo-convex portions formed on the front and back surfaces; A heat exchange flow path and a second heat exchange flow path, the first heat exchange flow path is used for the flow of the first heat exchange fluid, the second heat exchange flow path is used for the flow of the second heat exchange fluid, and the plurality of plates are respectively There are two through holes through the front and back sides for the introduction and export of the first heat exchange fluid, and the plate stacked body has: a first partition weir formed in the plate surface formed by the plurality of plates At least one of the two plate surfaces of the first heat exchange channel is inclined with respect to the center line connecting the centers of the two through holes, and is arranged so as to be opposite to each other when viewed in the overlapping direction of the plates. The center line is bilaterally symmetrical; and a flow path is formed along the center line on the side of the through-hole into which the first heat exchange fluid is introduced.

Description

Technical field [0001] The present disclosure relates to a plate heterogeneity and a heat exchanger including the plate. Background technique [0002] It is known that the plate heavier of the plate heat exchanger, the shell plate heat exchanger, etc. is configured by a plurality of sheets having a specific uneven pattern in front of the front and opposite sides. The plate massage is configured to form a heat exchange flow path on one of the front and negative surfaces of each plate, and other heat exchange flow paths are formed on the other side, so that two heat exchange along the two heat exchange flow paths respectively. The fluid is heat exchange via the plate. Thereby, the heat transfer area can be increased to obtain excellent heat exchange efficiency. [0003] The applicant proposed a solution: in the shell plate heat exchanger applied to the evaporator of the refrigeration device, the shape of the plate constituting the plate recomphetic body is non-circular, thereby ena...
