Abstract
A plate-type heat exchanger may include a housing. The housing may include a plurality of rectangular plate-like components that are box-like components each having the same shape and having a standing wall section along a peripheral edge. One of the box-like components may be layered on another components reversed in the horizontal direction to form a layered structure having an upper layer component and a lower layer component such that an upper portion of a standing wall section of the lower layer component of the layered structure is fit into a lower portion of a standing wall section of the upper layer component of the layered structure. The angle (θ) of the standing wall sections may be θ≤30°, and at least a portion of a contact region between the upper portion and the lower portion may be joined by solid phase diffusion bonding.
