Abstract
In a plate type heat exchanger, a radius of curvature R1 of the protrusions formed in first plates is greater than a radius of curvature R2 of the depressions formed in the first plates to provide a plurality of asymmetrical flow paths.
Claims17
A plate type heat exchanger comprising:
- a plate package in which a plurality of heat exchange plates is stacked to form a flow path, through which fluid flows;
- an end plate coupled to an outside of the plate package;
- and
- a socket connected to the plate package by passing through the end plate,
- wherein the plurality of heat exchange plates includes:
- a plurality of first plates in which a plurality of protrusions protruding upward from a plate body and a plurality of depressions recessed downward from the plate body are alternately arranged;
- and
- a plurality of second plates having a shape symmetrical to that of the first plates in a vertical direction,
- wherein the plurality of first plates and the plurality of second plates are alternately stacked one by one in the vertical direction,
- wherein the protrusions of the first plates are coupled to depressions of the second plates,
- wherein the depressions of the first plates are coupled to protrusions of the second plates, and
- wherein a radius of curvature R1 of the protrusions formed in the first plates is greater than a radius of curvature R2 of the depressions formed in the first plates to provide a plurality of asymmetrical flow paths.
