Title:
PLATE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2010/120125
Kind Code:
A2
Abstract:
The present invention relates to a plate heat exchanger for largely improving heat exchange efficiency by improving the flow of fluids. The plate heat exchanger of the present invention comprises a plurality of heat exchange tubes stacked in the vertical direction, each formed by coupling upper and lower plates with each other, and each having a 1st flow channel in which a 1st fluid flows, and a 2nd flow channel formed between the heat exchange tubes for the flow of a 2nd fluid, wherein each of the heat exchange tubes has an inlet path and an outlet path separated from each other on both ends, the upper plate has an upper flange protruded from the upper parts of the inlet path and the outlet path, the lower plate has a lower flange protruded from the lower parts of the inlet path and the outlet path, a plurality of upper flow grooves are extended in an oblique direction on the bottom surface of the upper plate, a plurality of lower flow grooves are extended in an oblique direction on the top surface of the lower plate, the upper plate and the lower plate form the first flow channel by being coupled with each other in such a manner that the upper flow grooves and the lower flow grooves intersect each other, and in the periphery of the inlet path and the outlet path of the upper plate and in the periphery of the inlet path and the outlet path of the lower plate are provided structures for guiding the flow of the fluids in two or more directions.
