Abstract:
Plate heat exchanger includes heat transfer plates each including heat transfer portion with 1st surface and 2nd surface, heat transfer portions stacked in 1st direction, 1st channel for circulating 1st medium in 2nd direction orthogonal to 1st direction formed between opposed 1st surfaces, and 2nd channel for circulating 2nd medium in 2nd direction formed between opposed 2nd surfaces. Each heat transfer portion includes barrier ridges on 1st surface that extend in direction crossing 2nd direction, divides heat transfer portion into divided areas in 2nd direction, and crosses and abuts against ridges of 1st surface of opposed heat transfer portion. Each heat transfer portion includes 2nd flow channel forming valleys on 2nd surface arranged at intervals in 3rd direction orthogonal to both 1st and 2nd directions in each divided area from its one end to its other end in 2nd direction.

Claim (Index 1):
A plate heat exchanger, comprising:\n a plurality of heat transfer plates each including a heat transfer portion having a first surface on which ridges and valleys are formed, and a second surface that is opposed to the first surface and on which valleys being in a front-back relationship with the ridges of the first surface and ridges being in a front-back relationship with the valleys of the first surface are formed, the plurality of heat transfer plates respectively having the heat transfer portions stacked on each other in a first direction, wherein the first surface of the heat transfer portion of each of the plurality of heat transfer plates is arranged opposed to the first surface of the heat transfer portion of an adjacent heat transfer plate on one side in the first direction, and the second surface of the heat transfer portion of each of the plurality of heat transfer plates is arranged opposed to the second surface of the heat transfer portion of an adjacent heat transfer plate on an other side in the first direction, wherein a first flow channel through which a first fluid medium is circulated in a second direction orthogonal to the first direction is formed between the first surfaces of the heat transfer portions of each adjacent heat transfer plates, and a second flow channel through which a second fluid medium is circulated in the second direction is formed between the second surfaces of the heat transfer portions of each adjacent heat transfer plates, and wherein the heat transfer portion of at least one of each adjacent heat transfer plates comprises: as the ridges formed on the first surface, at least one barrier ridge that crosses a centerline extending in the second direction of the heat transfer portion and is formed over the entire length in a third direction orthogonal to the first direction and the second direction of the heat transfer portion, and that divides the heat transfer portion into two or more divided areas in the second direction, the at least one barrier ridge crossing and abutting against the ridges formed on the first surface of the heat transfer portion of the opposed heat transfer plate aligned adjacently, and as the valleys formed on the second surface, a plurality of second flow channel forming valleys constituting part of the second flow channel, the plurality of second flow channel forming valleys being arranged at intervals from each other in the third direction in each of the two or more divided areas from one end to an other end in the second direction of each corresponding one of the two or more divided areas.
