Background technology
Along with the raising of people's living standard, solar water heater is energy-conservation with it, advantage enters into huge numbers of families rapidly efficiently.Main employing solar vacuum heat-collecting pipe absorbs the heat of the sun in the prior solar water heater, and this heat is kept in the storage tank of top by circulation, thereby reaches the purpose that makes full use of solar heat-collection.
Existing solar vacuum heat-collecting pipe is made up of two concentric circles glass tubes as the thermos flask of an elongation, is evacuated between inside and outside Circular glass pipe.Heated fluid is positioned at inner layer glass.The inner layer glass tube outer surface, selectivity applies heat absorbing coating usually, is beneficial to more convert sunshine to heat energy the heat-transfer fluid in the heating inner glass tube.The solar vacuum heat-collecting pipe material of this structure, technology and simple in structure, good reliability, and cost is lower, and therefore by large-scale production and use, application prospect is extensive.
But this thermal-collecting tube inner capacities is bigger, with 44 millimeters of internal diameters, interior length of tube is that 1750 millimeters thermal-collecting tube is an example, it can adorn about 6 jin in water, if a solar water heater has 20 such thermal-collecting tubes, water capacity is 120 jin in it, after that is to say that every day, all need heated these 120 jin of water earlier, just can conduct the heat in the storage tank, therefore to go out hot water speed slower for the solar water heater made of this thermal-collecting tube, increase the heat exchanger time that is heated fluid and external environment, thereby caused heat waste higher.
The utility model content
For overcoming above-mentioned defective, the purpose of this utility model is to provide a kind of simple in structure, the fluid thermal conduction is fast, heat waste is few economic benefits and social benefits solar vacuum heat-collecting pipe.
For achieving the above object, economic benefits and social benefits solar vacuum heat-collecting pipe of the present utility model, form by managing in tubular outer tube and the two arc, described outer tube and interior pipe are in the vacuum seal of upper end open place, be vacuum between outer tube and the interior pipe, the support of pipe in the lower end is provided with and supports in outer tube, the hypomere of the cavity between described outer tube and interior pipe is added with heat-conducting work medium, and the cross section of described interior pipe is a crescent or semi-circular.
Particularly, the vacuum sealing mode at described outer tube and interior pipe upper end open place is: be provided with sealing column between described outer tube and interior pipe, be axially arranged with passage on described sealing column, described passage divides upper and lower two sections; Wherein the diameter of epimere passage is greater than the diameter of hypomere passage, and upper and lower two sections passages become stepped; On the stage casing of described epimere passage or epimere inwall, be provided with screw thread; In described epimere passage, be provided with the sealed silicon glueballs of diameter, on described sealed silicon glueballs, be provided with and the suitable puller bolt of epimere passage diameter greater than the hypomere passage.
Particularly, pipe orthodrome outer wall surface is coated with heat absorbing coating in described.
Particularly, be provided with the air discharge duct that at least one emptying is used in described puller bolt side.
In the said structure,, form heat pipe, played the effect of economic benefits and social benefits heating, increased heat conduction efficiency greatly thereby make between outer tube and the interior pipe by among described outer tube and interior pipe, being added with heat-conducting work medium; And after changing interior tube shape, can be under the situation that does not reduce heating surface area, the fluid in the minimizing solar vacuum heat-collecting pipe that can be a large amount of, thus accelerated heat conducting speed greatly, reduced heat waste, overall structure is simple, uses easy to process.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As Fig. 1 and shown in Figure 5, the utility model economic benefits and social benefits solar vacuum heat-collecting pipe is made up of pipe 2 in tubular outer tube 1 and the two arc, and the cross section of described interior pipe 2 is a crescent or semi-circular, the support of pipe in the lower end is provided with and supports in outer tube; Described outer tube 1 and interior pipe 2 are in the vacuum seal of upper end open place, cavity part 3 between outer tube and the interior pipe is a vacuum, be added with heat-conducting work medium (as ethanol, ether etc.) at cavity 3 hypomeres, form heat pipe, increased heat conducting speed and efficient so greatly thereby make between outer tube and the interior pipe.This structure can also be under the situation that does not reduce heating surface area, the fluid in the minimizing solar vacuum heat-collecting pipe that can be a large amount of, thereby accelerated heat conducting speed greatly, reduced heat waste, played the effect of economic benefits and social benefits heating, overall structure is simple, uses easy to process.
As shown in Figures 2 and 3, above-mentioned crescent or semi-circular interior pipe are made up of orthodrome sidewall and roundlet arc sidewall, are adding man-hour, and the spacing between the inwall of orthodrome sidewall and roundlet arc sidewall can made more than 1 millimeter with processing technology as required.
Heat absorption intensity for pipe in strengthening as shown in Figures 2 and 3, should be coated with heat absorbing coating 4 at the sidewall outer surface of interior pipe orthodrome one side at least.
As shown in Figure 4 and Figure 5, the vacuum sealing mode at described outer tube and interior pipe upper end open place is: be provided with sealing column 6 between described outer tube and interior pipe, be axially arranged with passage 7 on described sealing column, described passage divides upper and lower two sections; Wherein the diameter of epimere passage is greater than the diameter of hypomere passage, and upper and lower two sections passages become stepped; On the stage casing of described epimere passage or epimere inwall, be provided with screw thread; In described epimere passage, be provided with the sealed silicon glueballs 8 of diameter, on described sealed silicon glueballs, be provided with the puller bolt 9 suitable with epimere passage diameter greater than the hypomere passage.Adopt said structure, can prevent effectively that working medium from using for a long time reduces or disappears; Usually after using one to two year, can open puller bolt 9, take out sealed silicon glueballs 8, and add heat-conducting work medium, and after vacuumizing, utilize bolt then the silica-gel sphere top tight sealing in the thermal-collecting tube upper end.There is not condition, also can be after adding heat-conducting work medium, then with the interior pipe filling part high-temperature-hot-water of thermal-collecting tube and then insert in the high-temperature-hot-water in the outer tube lower end, heat-conducting work medium is seethed with excitement rapidly, the heat-conducting work medium of boiling can be discharged the air in the cavity rapidly, and utilize puller bolt 9 that sealed silicon glueballs 8 top tight sealings are got final product this moment more rapidly.
Further improve as the utility model, discharge and puller bolt rapidly, be provided with the air discharge duct (not shown) that at least one emptying is used in described puller bolt side for the ease of above-mentioned air; Certainly, if processing conditions allows, also can on the sidewall of passage 7, air discharge duct be set as shown in Figure 4.Like this, can after add heat-conducting work medium, earlier puller bolt 9 and sealed silicon glueballs 8 be inserted in the passage, but not hold out against; After heat-conducting work medium was heated boiling, the air of expansion then jack-up sealed silicon glueballs 8 was discharged by air discharge duct, with puller bolt 9 sealed silicon glueballs 8 top tight sealings is got final product after discharging air again, and this mode seals comparatively rapid.
