The invention relates to the technical field of chemical engineering equipment, and provides a heat transfer structure which comprises heat-transfer splicing units, wherein a plurality of first flow guide bulges and second flow guide bulges are arranged on each heat-transfer splicing units; every two heat-transfer splicing units are spliced to form a splicing unit pair; fluid channels with different corrugation depths and corrugation angles are formed through the first flow guide bulges and the second flow guide bulges in each splicing unit pair; n splicing unit pairs are combined to form oneheat transfer structure, to form 2n-1 fluid channels, and to form multi-ratio fluid distribution; and n is greater than or equal to 2. Consequently, the problem about a flow mismatch in the running process of a heat exchanger can be solved; the heat transfer structure is mounted in an equipment frame and a product is assembled in the form of a sealing structure, so that the high-temperature-resistant and high-pressure-resistant characteristics of the heat exchanger can be achieved; and through the design of the corrugation angles, the sheet heat transfer coefficient can be improved and the resistance to the heat exchanger can be reduced.
Description
technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to a heat transfer structure and a heat exchanger. Background technique [0002] Heat exchange equipment is an indispensable equipment in the industry. Under the existing technical conditions, the plate heat exchanger needs to achieve the effect of different medium circulation spaces (that is, the volumes of the two adjacent heat exchange media flow through are different. The same), generally the asymmetric corrugated plate structure is used, so that the two adjacent corrugations are not consistent. However, in this way, since the heat transfer structure medium enters the heat exchanger in equal proportions, there is a problem that the flow rate of the heat exchanger does not match during operation. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a heat transfer structure aimed at solving the problem ...
