Description
The invention belongs to F
28Heat-exchange device among the D, it is specifically related to novel heat-conducting medium and uses the structure of the radiator of this heat-conducting medium.
Traditional radiator is full of formula for heat-carrying matter, the temperature difference of dependence radiator inside and outside wall is finished the process of heat exchange, the shortcoming of this radiator is the quantitative limitation that is subjected to heat exchange area and heat-carrying matter, otherwise will increase the volume of radiator, certainly will cause the waste of steel, and this kind form heat transfer efficiency low, waste energy.In recent years along with the development of development of science and technology hot pipe technique is very fast, therefore also occurring utilizing the sensitive materials that are being subjected to be easy to generate in the thermal process phase transformation on the radiator, the effect of emitting the latent heat of vaporization being subjected to thermal evaporation during in condensation realizes the heat abstractor of high-efficiency heat conduction.Know that through Patent Office of the People's Republic of China retrieval following several patent family is still arranged: 1. CN88208071,7 " heat pipe effect radiator ", it is to adopt a plurality of vertical volatile liquid cavities that are equipped with, the heat-carrying pipe is eccentric configuration by the bottom of heat radiation cavity; 2. CN86205331 " a kind of long-acting energy-saving warmer ", it is with electrical heating simple substance or two matter working solution, phase transition process heat conduction and heat radiation by working solution, adopted the methaneseries halogen derivatives of methaneseries in its working solution, this is a kind of harmful organic substance, relatively more dangerous under the condition of high temperature, and its heat-carrying pipe is eccentric the setting in service pipe; 3. CN87213030 " phase-change type domestic heating device " it be adopt to go up lower collecting box and liquid back pipe heat radiating fin structure, come heat conduction and heat radiation with organic medias such as electrical heating alcohol or alkyl compounds; 4. CN87212734 " a kind of indirect-heating radiator ", it is that it has adopted the micropore reduction technique in the hot pipe technique, but does not point out working media with the heating tube heating work medium that the is tied with copper mesh heat radiation of conducting heat.The characteristics of above several patents technology are: adopt organic media, and there is bigger danger in the medium that has under certain state more; Moreover their heat-carrying pipe mostly is eccentric setting.
The objective of the invention is to make it simple in structure for improving hot pipe technique radiator in the aforementioned techniques, improve heat transfer efficiency, the spy provides a kind of novel inorganic heat transfer medium and a kind of novel heat spreader structures.
By as above design, the radiator of the no-falling heat-transfer formula of the employing high-efficiency heat conduction medium that this programme provided includes heat-carrying pipe and radiator, its concrete feature is: its radiator be by the loop pipe of upper level, middle many vertical heat pipes, and the thermocouples tube of lower horizontal form the closed container of multichannel intercommunication, its heat-carrying pipe is by passing through both with one heart strict but mutual sealings in the thermocouples tube; After vacuumizing, radiator charges into the high-efficiency heat conduction medium.
The structure of the radiator in this programme is:
The heat-carrying pipe compares with the diameter of thermocouples tube: 2/3: 1～1/4: 1
The length of heat pipe and the diameter of thermocouples tube ratio: 20～22 times
Heat pipe diameter and thermocouples tube diameter were than 2: 3
Gap 1.5～40mm between heat-carrying pipe and the thermocouples tube.
Be welded with a plurality of conical air deflectors on its heat-carrying pipe of radiator inside, the center of each air deflector and each heat pipe center align.Its radiator enclosure space vacuumizes the back gauge pressure should be less than-0.15MPa.The Concentricity tolerance of its heat-carrying pipe and thermocouples tube requires should be less than 0.1mm/m.It heat pipe around be provided with additional heat abstractor.
The heat-conducting medium that is used for no-falling heat-transfer radiator that this programme provides, it is characterised in that this heat-conducting medium is made up of the plurality of inorganic salt class,
It is siliceous 0.5～5% years old
Chromium 0.8～8%
Potassium 0.1～1%
Sodium 2～20%
Barium 4～10%
Its reinforcement pH value distilled water
The strontium or the beryllium that also have minute quantity.
Optimum value through this plurality of inorganic salt class proportioning of test of many times is:
Siliceous 2～3.2%
Chromium 3～4%
Potassium 0.2～0.6%
Sodium 10～15%
Barium 6～8%
All the other are the distilled water of high pH value
The strontium or the beryllium that also have minute quantity.
Maximum characteristics are high-efficiency heat conduction media of having selected for use inorganic salts to form in this programme, be a kind of liquid substance of hot superconduction, know its not only safety, stable through test, and obtain flank speed and high efficiency, its speed and efficient all are surprising, and speed can reach the subsonic stage.The characteristics that have again are that heat-carrying pipe and thermocouples tube are concentric arrangement, and are provided with a plurality of air deflectors on the heat-carrying pipe, and the heat-carrying that is in operation pipe does not contact basically with the medium liquid level.Owing to adopt above measure, this device cranking temperature is lower, just can start in the time of 48～52 ℃ and devote oneself to work.Heat conduction velocity is very fast, when starting back moment heat pipe and the whole heating of return duct, does not have the no fouling of corrosion through the test of many times device inwall of finding to loose.
Adopt this programme can embody following superiority: 1. the heat-conducting medium of Cai Yonging is an inorganic salts, has the characteristics of safety and stability; 2. adopt heat-carrying pipe and thermocouples tube concentric arrangement and air deflector is housed and must has the loop pipe on top to communicate, it is express to make its conduct heat, and reaches the tight velocity of sound stage, the radiating efficiency height; 3. start-up temperature is low; 4. need the amount of the heat-carrying working medium that drops into to reduce significantly, so it is energy-efficient device.
Fig. 1 is the outside drawing of this programme no-falling heat-transfer radiator;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is Figure 1B-B cutaway view.
Among the figure: (1)-loop pipe; (2)-heat pipe; (3) Fu Jia heat abstractor, warm-air pipe; (4)-thermocouples tube; (5)-the heat-carrying pipe; (6)-air deflector.
The embodiment of this programme can be designed to series of products according to the heat supply needs.Now with heat supply 15m
2Be example, its heat sink size is 1000 * 630 * 33mm.Its radiator adopts G
10Material, heat-carrying pipe ∮ 22 * 2.5mm, thermocouples tube ∮ 33 * 1.5mm.The heat-carrying working medium of this programme can adopt hot water, also can use superheated steam.Therefore additional heat device on its heat pipe may can arbitrarily dispose under the situation just for enlarging area of dissipation, and this programme is to add airduct on fin again, knows at the airduct place that through test tangible thermal current is arranged.The radiating appliance of this programme has been widely used, and except that making radiator, also can be used to do drying plant, heat transmission equipment, or collecting apparatus.Its thermal source can be used the various forms of vapour, water, coal, electricity, underground heat or solar energy.
