Foam material is made.
Because metal foam refers to the special metal material containing foam pore, with high aeration, it is usually used in making stream
Body filter, therefore the spiral band being made using metal foam, when spiral band carries out flow-disturbing work, in heat exchanger
Liquid in impurity can enter foam pore, cause impurity to deposit, block spiral band on foam pore, bad cleaning.
Nano material refers at least one-dimensional in nano-scale (0.1-100nm) or by their conducts in three dimensions
The material that elementary cell is constituted, this is about as much as the yardstick that 10～100 atoms are arranged closely together, therefore nano material
With high intensity and high rigidity, and nano-material surface has hydrophobicity, will not be infected with impurity, it is ensured that nano-material surface is all the time
Keep cleaning.
The content of the invention
The purpose of the present invention is intended to provide that a kind of intensity is higher, and keeps many flow-disturbing spiral bands of spiral band cleaning
Device.
Many flow-disturbing spiral vinculum apptss in this programme, including support, are connected with spiral band, the spiral knob on support
Band is made up of nano material, and the nano material is made up of following material, and according to weight ratio, ZrO2 accounts for 30～60%, Al2O3 and accounts for
20～35%；Si3N4 account for 20～45%, TiO2 account for 2～10%, Mn account for 0.05～0.1%, Si account for 0.05～0.1%, S account for 1～
2%th, P accounts for 0.05～0.60%.
The operation principle of this programme：Spiral band is rack-mount, then many flow-disturbing spiral vinculum apptss are inserted
Heat exchanger tube, when fluid enters heat exchanger tube after, stopped by spiral band while flow of fluid, make fluid in heat exchanger tube
Portion forms turbulent flow, improves the flowing velocity of fluid, so as to improve heat exchange efficiency, due to spiral band be use nano material by
30～60%, Al2O3 is accounted for according to ZrO2 account for 20～35%；Si3N4 account for 20～45%, TiO2 account for 2～10%, Mn account for 0.05～
0.1%th, Si accounts for 0.05～0.1%, S and accounts for 1～2%, P and account for 0.05～0.60% proportioning and makes, now the quality of spiral band
Lighter in movement, and there is no pore in spiral band surface, impurity that will not be in fluid-absorbent, it is ensured that spiral band exists
Cleaning is kept during Long-Time Service, without changing, the service life of spiral band is improved.
The beneficial effect of this programme：The present invention makes spiral band using nano material, makes spiral band keep high intensity
And cleaning, improve the service life of spiral band.
Further, the nano material is made up of following material, and according to weight ratio, ZrO2 accounts for 44%, Al2O3 and accounts for 25%；
Si3N4 accounts for 25%, TiO2 and accounts for 4%, Mn and account for 0.08%, Si and account for 0.07%, S and account for 1.5%, P and accounts for 0.35%, now spiral band tool
There are high intensity and high rigidity, will not damage, be easy to Long-Time Service.
Further, the nano material is made up of following material, and according to weight ratio, ZrO2 accounts for 40%, Al2O3 and accounts for
20%；Si3N4 accounts for 30%, TiO2 and accounts for 8.3%, Mn and account for 0.05%, Si and account for 0.05%, S and account for 1.05%, P and accounts for 0.55%, now spiral shell
Knob band has high intensity and high rigidity, will not damage, and is easy to Long-Time Service.
Further, the spiral band is cored screw tie, and fluid can flow through hollow position and through spiral band,
The contact area of spiral band and fluid is increased, the flowing velocity of fluid is increased, so as to improve heat exchange efficiency.
Further, the spiral band is welded with support, it is ensured that spiral band forms one with support, with holder pivots
Drive spiral band to rotate together, make spiral band convection current body form turbulent flow, break retention layer, improve heat exchange efficiency.
