Abstract
Official abstract text for this publication.
A heat exchanger may include a stacked plurality of plates and a fin plate brazed to each other. Each set of adj acent said plates of the plurality of the plates may define a flow path between plates. Each plurality of the plates may include a flow-through portion penetrating through the plates and through which a fluid is flowable. At least one set of the flow-through portions may be provided at one of the flow paths such that the fluid is flowable from one side of a flow-through portion to an other side of a flow-through portion. The flow-through portion may be disposed outside the fin plate. Each plurality of the plates may further include a through hole disposed outside the fin plate. Each plurality of the plates may further include a first boss portion formed in a substantially elliptical shape surrounding the flow-through portion and the through hole.
First claim
Opening claim text (preview).
1 . A heat exchanger, comprising a stacked plurality of plates and a fin plate brazed to each other, wherein: each set of adj acent said plates of the plurality of the plates defines a flow path between plates through which fluid is flowable; each plurality of the plates includes a flow-through portion penetrating through the plates and through which a fluid is flowable, and at least one set of the flow-through portions is provided at one of the flow paths such that the fluid is flowable from one side of a flow-through portion to an other side of a flow-through portion; the flow-through portion is disposed outside the fin plate, across the fin plate as seen in a plan view; each plurality of the plates further includes a through hole disposed outside the fin plate, across the fin plate as seen in the plan view; and each plurality of the plates further includes a first boss portion formed in a substantially elliptical shape surrounding the flow-through portion and the through hole, the first boss portion protruding at each of the plates adjacent in a stacking direction until abutting each other. 2 . The heat exchanger according to claim 1 , wherein two sets of the flow-through portions are provided, and wherein: one side of a set of the flow-through portions is provided on an inner side of an outer periphery edge of the first boss portion, as seen in the plan view; another side of a set of the flow-through portions is provided on an outer side of the outer periphery edge of the first boss portion; the other side of a set of the flow-through portions is formed extending widely in a substantially extending direction of the first boss portion, and a second boss portion is formed at a perimeter thereof, the second boss portion protruding until abutting with the plate adjacent to the outer periphery edge of the first boss portion as seen in the plan view, and adjacent in a direction opposite to the first boss portion. 3 . The heat exchanger according to claim 1 , wherein the through hole includes a third boss portion protruding in a reverse direction relative to the first boss portion, until abutting with the plate adjacent in a stacking direction.
