Abstract
The present invention relates to a heat-pipe working medium composed of inorganic materials. It is characterized by that said working medium contains the following ingredients: red vanadic potassium, lithium carbonate, sodium perborate, boric acid, aluminium hydroxide, sodium superoxide, manganese peroxide, cobalt oxide and lead tetraoxide. Its advantages are that: the working medium is fully made up by proportioning the above-mentioned inorganic materials, and can conduct heat by means of inorganic molecular motion, and the above-mentioned chemical materials can produce a physical change by the action of a heat source with temp. of above 60-70 deg.C, and firstly can produce energy, and then give heat, so that the thermoconductive coeffient of said working medium is large, and its thermoconductive efficiency is high.
Description
The present invention relates to a kind of heat-pipe working medium of forming by inorganic materials that is applicable to gravity assisted heat pipe.
In the prior art, the general heat-pipe working medium such as the water capacity easily produce H
2The idle defective of heat pipe section can appear in incondensable gases such as gas, life-time service, and heat transfer efficiency greatly reduces; And high-temperature heat pipe working medium such as mercury, caesium, potassium, sodium etc. use the manufacturing process of above-mentioned working medium heat pipe comparatively complicated because its price is higher in addition in existing, also are difficult for extensive popularizing to use; Recently as heat-pipe working medium, but its thermal conductivity is less with organic substance for some that occur, and thermo-efficiency is not high.The above working medium also compares sternly the material of making heat pipe, the requirement of material in addition, also makes its use limited.
A kind of heat-pipe working medium of forming by inorganic materials that purpose of the present invention is developed at existing problem in the above-mentioned prior art just, this heat-pipe working medium thermal conductivity is big, the heat conduction efficiency height, the interior pressure of generation is little, and the opposite heat tube tube wall does not have corrosion.
The objective of the invention is to realize by the following method:
This heat-pipe working medium contains following component in per 100 gram water:
Vanadium pentoxide kalium (K
2C
rO
7) 4～5 grams
Quilonum Retard (Li

Tri-lead tetroxide (Pb
3O
4) 0.01～0.02 gram
In the present invention, used water is preferably selected distilled water or deionized water for use.
The advantage that the present invention is compared with prior art had is: because this heat-pipe working medium is all prepared by certain component by inorganic substance, rely on inorganic molecule motion heat conduction, under thermal source more than 60～70 ℃ drives, chemical material generation physical change, elder generation generate energy, heat release again.Therefore this working medium thermal conductivity is big, the heat conduction efficiency height, antifatigue, the interior pressure that produces is little, applied widely, through test of many times, this heat-pipe working medium is not only applicable to pipe, also can be used for coil pipe, flat tube etc., its heat transfer property is all unaffected, and to equal non-corrosivenesss of material such as iron, aluminium, copper, alloys.Its effect is exemplified below: (1), we utilize this working medium to make a kind of 837W electric heating panel radiator, compare as the panel radiator of heat-conduction medium with the 1300W electricity consumption deep fat of selling on the existing market, its effect is basic identical.(2), we are with the weldless steel tube of φ 26mm, wall thickness 2mm, length overall 3.2m, on the pipe around on thickness be that 0.3mm, width are the fin of the aluminium strip of 14mm, fin pitch is 3mm, then pipe is made snakelike.After the working medium of packing into, seal the formation vacuum behind 150 ℃ of hot types, energising power 900W recorded that temperature is 60 ℃ on the 2.5M place sheet in 5 minutes, was 90 ℃ after 10 minutes, was 129 ℃ after 45 minutes.(3), the thermal conductance reactor of our the long 3M that does, feeding 450 ℃ of steam, to record the reactor outside wall temperature be 293 ℃, the temperature difference of the outer wall each point of whole reactor is ± 1 ℃, its internal pressure has only 0.93MPa
The present invention does with detailed description below in conjunction with embodiment:
