Printed circuit-type heat exchanger having integral structure

Abstract

A printed circuit-type heat exchanger having an integral structure is disclosed. The heat exchanger includes first channel plates configured such that a fluid path for fluid A is formed on one surfacethereof, extending towards two side directions, inflow and outflow parts for fluid A are formed on the fluid path for fluid A, and structures corresponding to inflow and outflow portions for fluid Bare formed on two sides; second channel plates configured such that a fluid path for fluid B intersecting with the fluid path for fluid A is formed on one surface of the second channel plates, and theinflow and outflow portions for fluid B are formed on two ends of the fluid path for fluid B; an upper plate attached to an upper surface of a fluid channel stack structure formed by alternately stacking two or more first and second channel plates on one another; and a lower plate mounted to the lower surface of the fluid channel stack structure.

Description

technical field

[0001] The present invention relates to a Printed Circuit Type Heat Exchanger, and more particularly, the Printed Circuit Type Heat Exchanger includes an integral structure and has a structure that eliminates dead space. Background technique

[0002] The prior art shell-and-tube heat exchangers are unfavorable in terms of heat transfer area per unit volume, requiring a shell large enough to accommodate thermal expansion, and heavy and heavy to handle a certain degree of heat exchange capacity. great equipment.

[0003] In particular, heat exchangers for LNG ships are required to have a certain degree of heat exchange capacity and occupy a small volume.

[0004] Therefore, the shell-and-tube heat exchanger in the prior art is difficult to be applied to LNG ships and the like due to its large volume and heavy weight.

[0005] Moreover, the maintenance of the conventional shell-and-tube heat exchanger is not easy, and a crane with a larger capacity, a handling...
