Title:
PLATE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2020/045595
Kind Code:
A1
Abstract:
The present invention provides a plate heat exchanger that can obtain a high heat transferability while preventing increased flow resistance of a fluid. The plate heat exchanger comprises a plurality of heat transfer plates that include heat transfer regions. A first channel, in which a first fluid flows in a second direction orthogonal to a first direction, and a second channel, in which a second fluid flows in the second direction, are formed to alternate in the first direction with the heat transfer plates serving as boundaries. The heat transfer regions have a plurality of recess and protrusion groups each of which includes protrusions and recesses that stretch in a direction slanted with respect to the centerline of same extending in the second direction and are arranged alternately along a virtual line extending in the direction that the protrusions and recesses are slanted, said plurality of recess and protrusion groups being arranged orthogonal to the slanted direction. Protrusions in a recess and protrusion group are disposed side by side with recesses in an adjacent recess and protrusion group. Recesses in a recess and protrusion group are disposed side by side with protrusions in an adjacent recess and protrusion group. Protrusions of a recess and protrusion group of adjacent heat transfer plates intersect and abut each other.
