Description
Technical field
The present invention relates to a kind of high-efficiency condensation heat exchanger tube for being widely used in the fields such as the energy, electronics, refrigeration, and in particular to
Be a kind of to improve the high-performance condensing heat-exchanging pipe based on biomimetic features that designs of condensing heat-exchange efficiency.
Background technology
Steam condensation heat transfer process is widely present in the industrial circles such as the energy, chemical industry, refrigeration, and steam condensation can produce big
Latent heat is measured, therefore the recycling of latent heat is particularly significant for energy-saving and emission-reduction.In refrigeration industry, using the condensation of condensation efficiency higher
Device can reduce condenser area, save material.In addition, when in steam there are during incoagulable gas, can liquid film or drop with
One layer of air film is formed between mixed gas so that resistance to mass tranfer is added between steam and gas-liquid interface or condenser wall, sternly
Condensing heat-exchange performance is weakened again.In conclusion condensation efficiency is improved, the heat in high efficiente callback steam condensation process, to me
State's industrial expansion and promotion energy-saving and emission-reduction are of great significance.
According to surface of solids microstructure and wetting characteristics, steam condensation can be divided into film condensation and pearl condensation.Pearl
Condensation is a kind of more efficient heat transfer type relative to film condensation, its condensation coefficient improves 1-2 number than film condensation
Magnitude.Heat transfer area can be greatly reduced in the realization of pearl condensation, and very big income is obtained in terms of economy and environment.It is but actual
On, pearl condensation be it is a kind of comprising drop coring, growth, merging, depart from dynamic circulation process, have Analysis On Multi-scale Features and
By multifactor impact.Pearl condenses the surface condition for being largely dependent upon heat exchanger tube, is industrially a kind of relatively difficult to achieve
And unstable condensate form.
Cactus is efficiently catchmented using the super hydrophilic material for the thorn structure for being distributed in stem surface, due to the point of needle-shaped thorn
End section radius is less than root section radius so that droplet is constantly transported under the action of laplace pressure difference to bore spine root
It is dynamic.After droplet is assembled in root, transmitted along the backbone groove with hydrophobic wax top layer, and assemble other droplets by its band
Walk, so as to complete a circulation of catchmenting.
Exchange tube surface is using one of major technique that process for treating surface is raising condensing heat-exchange efficiency, generally use
Pod road adds the modes such as low rib to increase heat exchange area, while condensation water is more easily discharged under the action of surface tension,
The thickness of condensate film is reduced, so as to achieve the purpose that to strengthen condensing heat-exchange.But the condensing mode that above method is realized is equal
For film condensation, condensate film is attached to one thermal resistance of formation on tube wall so that the gas for needing to condense can not direct contacting pipe
Wall, causes cooling energy recovery still relatively low, and the room for promotion for strengthening condensing heat-exchange is limited.
