Abstract
The invention discloses a kind of nanometer carbon-coating rough surface processing technology for two phase flow.The present invention is that acicular surface is produced on existing open molding techniques, then controls the granular size of nanometer carbon, is sprayed on acicular surface, improves roughness, and then allows bubble to be more prone to, and fast speed belt heat is to lift heat transfer property energy.
Description
Technical field
The present invention relates to nanometer carbon applied technical field, more particularly to a kind of nanometer carbon-coating rough surface for two phase flow
Processing technology.
Background technology
Nanometer carbon possesses high heat transfer in X-Y directions, can effectively go out temperature is dispersed, the cooled plate of two phase flow is set
, it is necessary to increase rough surface, fast endothermic, generates bubble, heat is taken away by bubble, at present setting in two phase flow cooled plate meter
Meter, common are acicular surface (copper product), channel surface (copper product), using surface is strengthened, strengthen the heat transfer property energy on surface
It is 5-10 times of smooth surface, common enhancing surface is as shown in Figure of description Fig. 1, due to needing micro Process in making,
In the prior art it is various forms of enhancing surfaces processing is not easy, volume production making on have it is many difficult and expensive, using how
Rice carbon control granularity size, is sprayed in cooled plate, to reach the effect of generation bubble.
Due to the technology of existing volume production processing, it is difficult to reach the demand of two phase flow, such as Figure of description Fig. 3, Fig. 4, Fig. 5 institute
Show, Fig. 4 and Fig. 5 are to be processed to produce by CNC, but are unable to reach die sinking commercialization, how on existing open molding techniques to produce pin
Shape surface, then the granular size of nanometer carbon is controlled, roughness is improved, fast speed belt heat can be that the present invention needs to solve to lift heat transfer property
Technical problem certainly.
The content of the invention
The present invention provides a kind of nanometer carbon-coating rough surface for two phase flow aiming at above-mentioned defect and processes
Technique.The present invention is that acicular surface is produced on existing open molding techniques, then controls the granular size of nanometer carbon, is sprayed on needle-shaped
On surface, roughness is improved, and then allows bubble to be more prone to, fast speed belt heat is to lift heat transfer property energy.
A kind of nanometer carbon-coating rough surface technology scheme for two phase flow of the present invention is to be sprayed using nanometer carbon
It is coated in raising two phase flow heat transfer property energy in cooled plate.
A kind of nanometer carbon-coating rough surface processing technology for two phase flow, specifically includes following steps：
（1）Acicular surface is produced on existing open molding techniques；
（2）The granular size of nanometer carbon is controlled, is sprayed on acicular surface, improves roughness, and then allow bubble to be more prone to.
Step（1）In, acicular surface be with it is aluminum extruded come Heatsink be made again with the mode of wire cutting.
The generation of bubble mainly walks the torrid zone, and Figure of description Fig. 2 is the principle of two phase flow bubble formation, and a-b is knot
Pressure inside structure increases because of heating；B-c is that inside configuration pressure is more than surface tension, and bubble is emerged from stomata；C-d is gas
Bubble, which is persistently increased to when buoyancy reaches big, just departs from stomata, forms bubble.Bubble be such as not easy to generate or generate it is excessive or too small, all
Heat transfer property energy can be influenced, influences the effect with heat.
Beneficial effects of the present invention are：The present invention is that acicular surface is produced on existing open molding techniques, then controls nanometer
The granular size of carbon, is sprayed on acicular surface, improves roughness, and then allows bubble to be more prone to, and fast speed belt heat is to be lifted
Heat transfer property energy.
Brief description of the drawings：
Fig. 1 show the various forms of enhancing surfaces of existing nanometer carbon；
Fig. 2 show the process of two phase flow bubble formation；
Fig. 3 show acicular surface schematic perspective view；
It is wide with the wide actual size figure (mm) of conduit that Fig. 4 show fin；
Fig. 5 show fin height actual size figure (mm)；
Fig. 6 show photo after nanometer carbon spray figure.
Embodiment：
For a better understanding of the present invention, below with instantiation come the technical solution that the present invention will be described in detail, but it is of the invention
It is not limited thereto.
Embodiment 1
A kind of nanometer carbon-coating rough surface processing technology for two phase flow, specifically includes following steps：
