Plate-type heat exchanger for transferring heat between two fluids has first fluid flowing vertically downward between plates vertical plates, while second fluid flows in zigzag pattern past baffles

摘要

The heat exchanger is shaped as a rectangular box. The first fluid (1) flows vertically downward between alternate pairs of plates and is collected at the bottom (5) to flow vertically downward through an outlet pipe (4). The second fluid (2) may be admitted at the lower left-hand corner and zigzags upward through a channel (3) past horizontal baffle plates in the spaces between the pairs of plates to exit at the top right-hand corner. The surfaces of the plates may be patterned for greater heat transfer.
