Description
Technical field
The present invention relates to solar energy heat utilization field, relate in particular to a kind of heat pipe and solar energy heat collection pipe of built-in phase-transition liquid.
Background technology
Heat pipe realizes the ideal chose that heat transmits fast and exchange.Heat pipe realizes high heat transfer, exchange by phase transformation, and utilize the evaporation of airtight cavity internal working medium, condensation phase transformation carries out heat transmission, its heat-transfer capability is dozens or even hundreds of times of traditional metal materials.Heat pipe the most frequently used is at present copper-aqueous systems.But the price comparison of copper is expensive, select the aluminium of cheap lightweight replace copper can be cost-saving.But this tubing is to its sensitivity of water electrode, easily at high temperature produce hydrogen with water reaction, the hydrogen of generation is assembled at condensation segment, forms on-condensible gas, makes heat pipe failure, even can blast.Adopt organic solvent such as methyl alcohol, ethanol etc. to replace water theory can be avoided the generation of hydrogen, but industrial methanol and ethanol are inevitably containing traces of moisture, have impact on the performance of heat pipe.Moisture as adopted the method for chemical refining to remove trace in organic solvent will inevitably increase cost, and must together heat pipe make process in and atmospheric isolation, avoid organic solvent secondary to absorb water, this is obviously unpractical.
In addition, the solar energy heat collection pipe made with heat pipe, heat transfer efficiency is high, thermal shock is little, the reverse heat waste of system when decreasing without sunshine, and the heat loss of supreme lower circulation line, the purposes of this thermal-collecting tube is not limited to and provides domestic hot-water, simultaneously also for the field such as steam turbine power generation and accumulation of energy.Therefore hot pipe type vacuum heat collection pipe represents the new developing direction of heat collector.But hot pipe type vacuum heat collection pipe does not also obtain general promotion and application, the price comparison of this mainly this thermal-collecting tube is expensive.Therefore, if thermal-collecting tube can be made by cheap aluminothermy pipe belt for copper heat pipe, the cost reducing solar energy collection tube will be conducive to.
Summary of the invention
Heat pipe and the solar energy heat collection pipe of built-in phase-transition liquid of the present invention overcome above-mentioned defect, provide nano molecular sieve dispersion phase-transition liquid in organic solvent, and this phase-transition liquid and aluminothermy duct ligation are closed, solves the problem of on-condensible gas in aluminium and steel heat pipe, and effectively reduce heat pipe cost.
The technical scheme of the heat pipe of built-in phase-transition liquid of the present invention is such: arrange phase-transition liquid in heat pipe, phase-transition liquid is set to organic solvent, has the nano molecular sieve fluid well-distributing dispersion of water absorbing capacity in organic solvent; Heat pipe is set to aluminothermy pipe.
The diameter of nano molecular sieve is 5nm ~ 1 μm, and aperture is 2.5 ~ 3.5.
Organic solvent is set to alcohols, alkane, nitrile.
Organic solvent is set to methyl alcohol or ethanol.
The technical scheme of solar energy heat collection pipe of the present invention is such: it comprises outer tube and heat pipe, in heat pipe, phase-transition liquid is set, heat pipe it comprise condensation segment and evaporator section, phase-transition liquid is set to organic solvent, have water absorbing capacity nano molecular sieve fluid well-distributing dispersion in organic solvent; Heat pipe is set to aluminothermy pipe.
The diameter of nano molecular sieve is 5nm ~ 1 μm, and aperture is 2.5 ~ 3.5.
Organic solvent is set to alcohols, alkane, nitrile.
Organic solvent is set to methyl alcohol or ethanol
Shell is set to pure aluminum or aluminum alloy.
The inwall of heat pipe arranges groove.
The operation principle of aluminothermy pipe of the present invention is such: the molecular diameter due to water is 3, ethanol select aperture be the molecular sieve of 2.5 ~ 3.5 as water absorbent, realize the good absorption to water.In addition, molecular screen material can absorb water when temperature is less than 350 degrees Celsius, meets the requirement of solar energy heat collection pipe opposite heat tube.Nano molecular sieve dispersion in a solvent, obtains nano-fluid, nano-fluid Brownian movement in a liquid and be adsorbed on the capillary wick that the nano material on tube wall formed and be all conducive to increase heat-transfer effect.
Nano molecular sieve fluid in the present invention does the aluminium of phase-transition liquid and steel heat pipe realizes by the following method:
1) by the molecular sieve ultrasonic disperse that activated in organic solvent, phase-transition liquid is obtained;
2) aluminum pipe or steel pipe are cleaned oven dry, adopt high speed Oil-Filled Spinning method to squeeze out capillary groove;
3) vacuumize with the aluminum pipe of capillary groove or steel pipe, filling phase-transition liquid, finally sealed.
Then selective heat absorbing coating is ultrasonically welded within the evaporator section that nano molecular sieve fluid does the heat pipe of phase-transition liquid, and with hot pressing envelope method and high-boron-silicon glass carry out sealing-in.High-boron-silicon glass pipe sealed after being vacuumized just obtains heat-pipe vacuum heat collecting pipe.
Molecular sieve adds in the phase-transition liquid of heat pipe by the present invention first, the moisture in molecular sieve opposite heat tube phase-transition liquid is utilized to absorb, for opening new research direction without the research of Water Heat Pipes, in addition, molecular sieve is nano level, is dispersed in phase-transition liquid, forms nano-fluid, can improve heat-transfer effect, be kill two birds with one stone.
