Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to these embodiments.

[0030] The present invention is based on the structure of the core body of the bionic curved rib row type micro interlaced alveolar heat exchanger. image 3 As shown in , 4, the core body includes a shell 1, and the core body is divided into two layers through the heat exchange plate 2 inside, which are respectively used as medium flow cavities for the flow of cold and hot medium fluids, and heat exchange is performed through the heat exchange plate 2. There are at least two layers of curved ribs in each cavity. The curved ribs are composed of several curved ribs 3 parallel to each other. The walls form a certain stagger angle α). The curvilinear ribs on two adjacent layers are intersected, that is, there is a certain angle β between the ribs on two adjacent layers.

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 exchanging equipment, and in particular relates to a bionic-based curvilinear rib-row micro-staggered alveolar heat exchanger core and a heat exchanger. Background technique [0002] Heat exchangers are widely used in industry. To achieve low energy consumption and high-efficiency operation of equipment in the fields of power, chemical industry, shipbuilding, refrigeration and machinery, the design of advanced heat exchangers is inseparable. In order to improve the heat transfer capacity of the heat exchanger, there are generally the following three means: increase the heat transfer temperature difference, increase the heat transfer area, and increase the convective heat transfer coefficient. In a heat exchanger without phase change, increasing the heat transfer temperature difference is usually achieved by rationally arranging the flow channels, such as making the hot and cold fluid flow countercurr...
