PLATE-TYPE HEAT EXCHANGER AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2015/125831

A1

This plate-type heat exchanger which ensures air-tightness can be easily produced by performing solid-phase diffusion bonding without using a brazing material in at least part of the joining of lateral-end surfaces of plate-type components constituting a plate-type heat exchanger, and the joining of a channel for upper and lower plate-type components. The present invention involves: a rectangular plate-type component constituting the heat exchanger case being a box-type component provided with a vertical wall section along the peripheral edge thereof; box-type components (1, 2) which have the same shape being configured in a manner such that the orientation of the horizontal surface of one of the box-type components is reversed; layering the box-type components (1, 2) in order; engaging the upper section of the vertical wall section of the lower-layer component with the lower section of the vertical wall section of the upper-layer component; setting the angle (θ) of the vertical wall section to θ≤30°; and performing solid-phase diffusion bonding in at least part of the contact site between the vertical wall section of the upper-layer component and the vertical wall section of the lower-layer component.
