Embodiment Construction

[0025] 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.

[0026] The present invention is based on the structure of the core body of the bionic linear rib row type micro-staggered alveolar heat exchanger. image 3 As shown, 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 linear ribs in each cavity. The linear ribs are composed of several linear ribs 3 parallel to each other. Body side walls form a certain staggered angle α, such as Figure 5 ). The linear ribs on two adjacent layers are arranged alternately, that is, there is a certain angle β between the ribs on ...

Abstract

The invention discloses a bionic straight-line-rib-row type tiny staggered alveolar heat exchanger core. The core comprises at least two layers of medium flowing cavities separated by a heat exchangeplate, at least two layers of straight-line type rib rows are arranged in each layer of medium flowing cavity, each straight-line type rib row is composed of a plurality of straight-line rib strips parallel to each another, and every two adjacent layers of straight-line rib strips are staggered. Bionic elements are integrated into the design of the heat exchanger to design the tiny staggered alveolar heat exchanger, the structure improves the performance of the heat exchanger from two aspects including the heat transfer coefficient and the heat transfer area, the structure is light and simpleand convenient, and the core is 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 linear 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 countercurrently...
