Embodiment Construction

[0087] Several embodiments of the present invention will be described below with reference to the accompanying drawings. However, dimensions, materials, shapes, relative arrangements, and the like of components described as embodiments or shown in the drawings are not intended to limit the scope of the present invention, but are illustrative examples.

[0088] For example, "in a certain direction", "along a certain direction", "parallel", "orthogonal", "center", "concentric" or "coaxial", etc. indicate a relative or absolute configuration The expression not only means strictly such an arrangement, but also means a state of relative displacement with a tolerance or an angle and a distance to the extent that the same function can be obtained.

[0089] For example, expressions such as "same", "same", and "homogeneous" indicating that things are equivalent state not only indicate a state of strict equality but also a state of difference in the degree to which there is a tolerance ...

Abstract

A plate stack according to an embodiment includes a plurality of plates each of which includes corrugated portions formed on a front surface and a back surface of each of the plurality of plates, andwhich are arranged in stacks and, first heat exchange flow passages through which a first heat exchange fluid flows and second heat exchange flow passages through which a second heat exchange fluid flows, the first heat exchange flow passages and the second heat exchange flow passages being formed between the plurality of plates to be arranged alternately along a stacking direction of the plurality of plates. Each of the plurality of plates has two through holes which penetrate the front surface and the back surface, and from which the first heat exchange fluid is introduced and derived. The plate stack further includes first partition weirs which are formed on at least one of two plate surfaces of a plurality of plate surfaces formed by the plurality of plates, the two plate surfaces forming a corresponding one of the first heat exchange flow passages therebetween, the first partition weirs being symmetrically arranged with respect to a center line connecting centers of the two through holes as viewed from the stacking direction of the plates so as to be oblique with respect to the center line, and a flow passage formed along the center line on a side of at least a through hole, of the two through holes, from which the first heat exchange fluid is introduced.

Description

technical field [0001] The present disclosure relates to a laminated plate body and a heat exchanger including the laminated plate body. Background technique [0002] It is known that a laminated plate body used in a plate heat exchanger, a shell-plate heat exchanger, etc. is composed of a plurality of laminated plates having specific concave-convex patterns on both front and back surfaces. The stacked plates are formed in such a way that a heat exchange flow path is formed on one of the front and back sides of each plate, and other heat exchange flow paths are formed on the other side, so that the two heat exchange paths that flow along the two heat exchange flow paths respectively are exchanged. The fluid is heat exchanged through the plates. Thereby, it is possible to increase the heat transfer area and obtain excellent heat exchange efficiency. [0003] The applicant of this case has proposed a plan: in the shell-plate heat exchanger applied to the evaporator of the re...
