Abstract

The invention discloses a curve-rib-row-type tiny staggered alveolus heat exchanger core based on bionics. The curve-rib-row-type tiny staggered alveolus heat exchanger core comprises more than two layers of medium flowing cavities partitioned by heat exchange plates. More than two layers of curve rib rows are arranged in each layer of medium flowing cavity, each curve rib row is composed of a plurality of mutually-parallel curve ribs, and every two layers of curve rib rows are arranged crosswise. Bionic elements are fused into the design of a heat exchanger, and the tiny staggered alveolus heat exchanger is designed; through the structure, the performance of the heat exchange is improved in the two aspects of the heat exchange coefficient and the heat exchange area; and the curve-rib-row-type tiny staggered alveolus heat exchanger core is light, simple and convenient in structure and suitable for an aerospace heat exchanger.

Description

Technical field

[0001] The invention belongs to the technical field of heat exchange equipment, and particularly relates to a core body and a heat exchanger of a micro-interlaced alveolar heat exchanger based on a bionic curved rib row type. Background technique

[0002] Heat exchangers are widely used in industry. The design of advanced heat exchangers is inseparable from the low energy consumption and efficient operation of equipment in the power, chemical, marine, refrigeration and machinery fields. In order to improve the heat exchange capacity of the heat exchanger, there are generally the following three methods: increase the heat exchange temperature difference, increase the heat exchange area, and increase the convective heat transfer coefficient. In a heat exchanger with no phase change, increasing the heat exchange temperature difference is usually achieved by rationally arranging the flow channels, such as making the cold and hot fluids flow countercurrently.
