Description

Oblique fin that dispels heat that is fit for 3D to print

Technical Field

The utility model belongs to the technical field of the heat dissipation, especially, relate to a heat dissipation inclined fin who is fit for 3D printing.

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 fins are key structures for heat exchange of the radiator, and the traditional process adopts a blanking process. When the radiator assembly adopts 3D to print whole shaping, be subject to 3D and print the processing characteristic of technology, often traditional fin structure is after printing, and inside bearing structure can't be got rid of. And the minimum wall thickness that present 3D metal printed is more than 0.2mm, and traditional fin wall thickness generally is less than 0.2mm, can cause the fin wall thickness that adopts 3D to print like this to be greater than 0.2mm, has reduced heat radiating area when increasing the windage.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned current situation, provide a radiator pipe structure that is fit for 3D and prints.

The utility model adopts the technical proposal that: a heat sink tube structure suitable for 3D printing, comprising: the carrier plate and set up oblique lug on the carrier plate, the setting that inclines that the lug is parallel to each other is on the carrier plate, oblique lug with the carrier plate plane is the angle of inclination, oblique lug is the angle of inclination with the horizontal plane.

A heat dissipation inclined fin who is fit for 3D and prints, adopt oblique lug with support plate plane and level are personally submitted the design at angle of inclination, in the time of increase heat radiating area, can realize exempting from to support again and print the shaping.

Detailed Description

The utility model provides a be fit for 3D and print radiator pipe structure is introduced below in combination with the figure:

please refer to fig. 1 and fig. 2, which are illustrations of the present invention, the oblique heat dissipating fin suitable for 3D printing includes a support plate 1 and an oblique protrusion 2 disposed on the support plate 1, the oblique protrusion 2 is disposed on the support plate 1 in parallel, the oblique protrusion 2 forms an angle of 20 ° with the plane of the support plate 1, and the oblique protrusion 2 forms an angle of 45 ° with the horizontal plane.

The thickness of the heat dissipation inclined fins is 0.2-0.3 mm.

The inclined convex blocks 2 not only ensure the heat dissipation area, but also can strengthen the interlayer structure of the flat tubes; under the condition of the same volume, the heat dissipation area is improved and is improved by more than 20% compared with the traditional right-angle corrugated fin, the inclined convex blocks 2 are opposite to each other, the support plate 1 and the horizontal plane form an inclined angle, and the heat dissipation inclined fins 3 can be guaranteed to realize the support-free printing forming.

During the use, fix the oblique fin of heat dissipation between the cooling tube, the oblique fin of heat dissipation with the cooling tube contact will the heat that the cooling tube absorbed passes away, realizes the heat dissipation.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
