Description
Technical field:
The present invention relates to heat conducting element technical field, refer in particular to a kind of heat pipe and the heat-conducting medium thereof with high-efficiency heat conduction effect.
Background technology:
Heat pipe is the high-efficiency heat conduction element used in the industry at present, and its operation principle is: the Rapid Thermal hereditary property utilizing heat-conduction principle and refrigeration filling, is delivered to the heat of thermal source rapidly outside thermal source through heat pipe.With regard to current research, the capacity of heat transmission of heat pipe exceedes the capacity of heat transmission of any known metal.The industry such as aerospace, military project, industrial high-precision product (as radiator) is widely used in before hot pipe technique.
Traditional heat pipe all has an airtight pipeline, is filled with the solution as heat-conducting medium in pipeline.When heat pipe is heated hand, heat-conducting medium undergoes phase transition the other end of heat pipe by being heated, then reflux after condensation.In the phase transition process of heat-conducting medium, heat is taken away rapidly.So the height of heat pipe for thermal conductivity efficiency has direct relation with its heat-conducting medium.What traditional heat-conducting medium adopted is water.But because the thermal conductivity of water is not high, its heat transfer efficiency is lower, and the heat conduction scope of water is narrower, generally within 100 degrees Celsius, adopt water easily to form corrosion and incrustation scale as heat-conducting medium simultaneously, make reduce the service life of heat pipe.So be directed to this, many producers have employed alcohol, glycerine, or the solution of many kinds of substance mixing is used as heat-conducting medium, to improve the service life of heat conduction efficiency and increase heat pipe.The present inventor is also based on this, through testing for a long time, proposes a kind of heat pipe efficiently.
Summary of the invention:
The object of the invention is to overcome prior art weak point, a kind of heat pipe and the heat-conducting medium thereof with high-efficiency heat conduction effect are provided.
The technical scheme that the present invention realizes the employing of its object is: this heat pipe comprises metal tube and is encapsulated in the heat-conducting medium in metal tube, and the making raw material of described heat-conducting medium and dose ratio thereof are: add following raw material in 1000 grams of deionized waters: potassium bichromate 40-60 gram; Boric acid 3-5 gram; Sodium perborate 8-12 gram; Sodium peroxide 2-4 gram; Calcium chloride 1-3 gram; Ethanol 6-10 gram; Manganese dioxide 0.5-1 gram; Zinc hydroxide 0.2-0.8 gram.
Furthermore, in technique scheme, described metal tube adopts the copper pipe with vacuum lumen.
Furthermore, in technique scheme, described ethanol is absolute ethyl alcohol.
The technique scheme that the present invention adopts, adopt inorganic raw material and Organic Ingredients to cooperatively interact, multiple material cooperatively interacts, and improves the heat transfer efficiency of product.First, raw material is formed in the solution potassium, sodium metallic element have good thermal conductivity.Chromium, manganese element mobility after being heated is higher, can improve the phase transition process of solution fast, and increase heat endurance.Wherein, potassium bichromate, chlorination have anti-freezing property simultaneously, and the two and borate complex improve the frost resistance of product.Moreover ethanol, when being heated, can form volatilization fast, increase the heat transfer efficiency of product further.Further, there is the chromium element belonging to high price in solution, it can have anticorrosive effect.Zinc hydroxide meta-alkalescence, checks sour corrosion in solution and occurs, and finally, adopts deionized water as solution main body, can reduce corrosion and the incrustation scale of water formation further.Utilize the heat pipe that heat-conducting medium of the present invention makes, its heat transfer efficiency improves 200-300% than the heat transfer efficiency of traditional general heat pipe, and its temperature be suitable for is wider.
Detailed description of the invention:
Below in conjunction with specific embodiment, the present invention is further described.
