Problems solved by technology

However, as far as the U-shaped tube structure and the traditional plate structure are widely used in the industry, the technology is relatively mature, and they are usually used in high-power equipment, but the mass is large, the installation is inconvenient, and local reflux is easy to form during the flow process, making It is difficult to further improve the overall heat exchange capacity

Embodiment 1

[0038] The embodiment of the present invention is based on the structure of the bionic three-dimensional spider web laminated tube heat exchanger, such as Figure 1-5 As shown, it includes a multi-layer regular hexagonal net-type pipeline 3, and the net-type pipeline 3 includes six bent tubes 6 with the same structure, specifically the first bent tube 61, the second bent tube 62, and the third bent tube. Bending tube 63, the 4th bending tube 64, the 5th bending tube 65, the 6th bending tube 66, each bending tube 6 gradually surrounds from the outermost side of the regular hexagon to the center of the regular hexagon, and in the regular hexagon The radius of the circumscribed circle of the polygon is bent toward the center to form a bent section 4, and the bent sections 4 of two adjacent bent tubes 6 are fixed together by flexible buckles 13, and the outer ends of all bent tubes 6 pass through corresponding The distribution pipeline 2 communicates with the inlet 1 , and the cen...

Embodiment 2

[0045] The embodiment of the present invention is based on the bionic three-dimensional cobweb laminated tube heat exchanger combined and expanded along the circumferential array, and the shunt pipelines 2 of each heat exchanger unit are connected to each other and evenly distributed; or the heat exchanger is combined in an axial array Expansion, the outlet 5 of the previous heat exchanger unit communicates with the inlet 1 of the next heat exchange unit; it can also be expanded along the circumferential and axial arrays at the same time, such as Figure 7-8 As shown; on the premise that the installation difficulty does not increase, a variety of overall structural forms can be obtained, which are easy to disassemble, assemble and expand, have good combination characteristics and installation flexibility, and are suitable for different heat exchange requirements and different installation spaces; due to the six The polygons have a self-similar structure. On the premise of ensur...

Embodiment 3

[0047] In addition to regular hexagons, the shape of the mesh pipeline 3 can also be a regular polygon structure such as a regular triangle, a regular quadrilateral, and a regular pentagon. The multi-layer regular polygon mesh pipeline 3 forms a compact cross-flow structure, which is stable High performance, the structure of multiple bent tubes 6 is exactly the same, and the installation positions are symmetrical to ensure that the fluid is evenly distributed in the shunt pipeline 2 and the mesh pipeline 3. Under the conditions of the same volume and the same heat transfer, each bend The path of the folded tube 6 is the shortest, greatly reducing the pressure drop; it has a small mass in a limited volume, which can meet the installation requirements under small load requirements.

[0048] The first bending section 4 and the last bending section 4 of the bending pipe 6 are located on the same radius or on different radii of the circumcircle of the regular polygon, such as Figu...

Abstract

The invention discloses a bionic-based three-dimensional cobweb laminated tube type heat exchanger. The heat exchanger comprises a multi-layer regular polygonal net-shaped pipeline, wherein the net-shaped pipeline comprises a plurality of bent pipes with the same structure; each bent pipe gradually encircles inwards to the center of the regular polygon from the outermost side of the regular polygon, and is bent towards the center on the radius of the circumcircle of the regular polygon to form a bent section; the bent sections of two adjacent bent pipes are fixed together by flexible buckles;the outer ends of all the bent pipes communicate with an inlet by corresponding shunt pipes; and one ends, close to the center, of all the bent pipes communicate with an outlet through a central confluence pipe. The heat exchanger has the advantages of high heat exchange per unit mass, uniformly distributed medium fluid, stable structure, low pressure loss, low probability of blockage and high adaptability, and can adapt to conventional deformation.

Description

technical field [0001] The invention belongs to the technical field of heat exchange equipment, and relates to a three-dimensional spider web laminated tube heat exchanger based on bionics. Background technique [0002] At present, the heat exchange of power electronics and chemical systems, as well as radiators and oil preheaters for automobiles and aeroengine systems mainly include heat pipe, fin, microchannel, plate and tube structures. Among them, the heat pipe radiator is mostly used for heat dissipation of electronic chips. It quickly and efficiently transfers heat from the cold end to the hot end through the "thermal superconductivity" effect of phase change and heat conduction, that is, the ability to quickly transfer heat from a small space to a large space. . Usually the main body of the heat pipe is composed of brass tubes, and the inside is a mesh adsorption structure composed of fine metal wires. One end is fixed in the high temperature area, which is the evapo...
