Abstract
The invention discloses a stacked heat exchanger which comprises core veneers. Pore passages are chiseled in each core veneer, and two ends of each pore passage are communicated. Equivalent spacing between every two adjacent pore passages is not more than 3mm. The spacing between each pore passage and the lower surface of each core veneer is not more than 2mm; the core veneers are similar in structure. The core veneers are stacked together, and the projection directions of the pore passages between layers form a 90-degree included angle. After the two layers of core veneers are stacked, edge gaps between the two layers are required to be sealed. The periphery of a stacked core is sealed with a casing and the edge of each pore passage surface. A fluid medium 1 flows into the heat exchange core from an inlet of the casing and flows out from an outlet. Another fluid medium flows into the heat exchange core from an inlet and flows out from an outlet. The stacked heat exchanger has the advantages that the heat exchanger as a whole is compact in structure, high in heat exchange efficiency, convenient to mount and simple in structure.
