Description

Radiator pipe structure suitable for 3D printing

Technical Field

The utility model belongs to the technical field of the heat dissipation, especially, relate to a radiator pipe structure that is fit for 3D and prints.

Background

3D printing, one of the rapid prototyping technologies, is a technology for constructing an object by printing layer by layer on the basis of a digital model file using an adhesive material such as molten metal (alloy), powdered metal (alloy), or plastic. The biggest feature of this technique is that it can produce articles of almost any shape. Has become the leading research field in China and China at present.

3D printing is typically achieved using digital technology material printers. In the past, the mold is often used for manufacturing models in the fields of mold manufacturing, industrial design and the like, and is gradually used for direct manufacturing of some products, and parts printed by the technology are already available. A computer three-dimensional design model is used as a blueprint, special materials such as metal powder, ceramic powder, plastics, cell tissues and the like are piled up layer by layer and bonded by means of laser beams, hot melting nozzles and the like through a software layering dispersion and numerical control forming system, and finally, an entity product is manufactured through overlaying forming. Different from the traditional manufacturing industry in which the raw materials are shaped and cut through machining modes such as a die and a turn-milling mode to finally produce finished products, the 3D printing method changes a three-dimensional entity into a plurality of two-dimensional planes, and the three-dimensional entity is produced by processing the materials and superposing the materials layer by layer, so that the manufacturing complexity is greatly reduced. The digital manufacturing mode can generate parts in any shape directly from computer graphic data without complex process, huge machine tool and much manpower, so that the production and manufacturing can be extended to a wider production crowd range, and 3D printing can be regarded as a main processing means of future small products.

The flat pipe is a channel for circulating cooling liquid in the radiator, and the traditional process adopts a blanking process and a welding process. When the radiator assembly adopts 3D to print whole shaping, be subject to 3D and print the processing characteristic of technology, often traditional flat tube structure is after printing, and inside bearing structure can't get rid of. And the convex-concave reinforcing ribs on the surface of the traditional flat pipe can cause the difficulty of metal printing and powder cleaning.
