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 high-efficiency solar simple in structure, that the fluid thermal conduction is fast, heat waste is few two heat collecting vacuum pipes.
For achieving the above object, the two heat collecting vacuum pipes of a kind of high-efficiency solar of the utility model, comprise solar vacuum heat-collecting pipe, coaxial core pipe or the plug of being provided with in described solar vacuum heat-collecting pipe, be provided with the working clearance more than 1 millimeter between described core pipe or plug outer wall and the solar vacuum heat-collecting pipe inwall, in the described working clearance, be interval with two or more isolation rubber pads on the same cross section.
Wherein, described isolation rubber pad was disposed in the working clearance of nearly solar vacuum heat-collecting pipe opening part.
Wherein, described core pipe or plug account for more than 1/10th of solar vacuum heat-collecting pipe inner capacities.
Wherein, be provided with carriage below core pipe in described solar vacuum heat-collecting pipe or the plug.
Further, described core pipe or plug are heat pipe, wherein, the evaporation ends of heat pipe is positioned at the solar vacuum heat-collecting pipe bottom, and the condensation end of described heat pipe is positioned at the position of the nearly opening of solar vacuum heat-collecting pipe or is positioned at beyond the solar vacuum heat-collecting pipe opening.Be provided with the heat pipe carriage below the heat pipe in described solar vacuum heat-collecting pipe.
Further, be coated with heat absorbing coating at described heat pipe inwall.
In the said structure, by in existing solar vacuum heat-collecting pipe, increasing core pipe or plug, 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, overall structure is simple, uses easy to process.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Extremely shown in Figure 7 as Fig. 1, the two heat collecting vacuum pipes of the utility model high-efficiency solar, comprise solar vacuum heat-collecting pipe 1, coaxial core pipe or the plug 2 of being provided with is provided with the working clearance more than 1 millimeter between described core pipe or plug outer wall and the solar vacuum heat-collecting pipe inwall in described solar vacuum heat-collecting pipe; In the described working clearance, be interval with two or more isolation rubber pads 3 on the same cross section, (referring to Fig. 5 and Fig. 6, isolation rubber pad among Fig. 6 is 4), in order to described core pipe or plug relative fixed in solar vacuum heat-collecting pipe, and keep interval between adjacent two isolation rubber pads of this working clearance, form the fluid passage, be beneficial to that heated fluid upwards flow in the storage tank 5 in the working clearance.In the said structure, by in existing solar vacuum heat-collecting pipe 1, increasing core pipe or plug 2, 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, overall structure is simple, uses easy to process.
Wherein, above-mentioned core pipe or plug can be selected various materials as required, as plastics, metal, pottery or glass etc., and that make hollow (as shown in Figure 2) as required or solid (as shown in Figure 1).For the ease of placing core pipe or plug, should below the heat pipe in the described solar vacuum heat-collecting pipe, be provided with carriage 4.Gap between two pipes of above-mentioned working clearance under being meant in working order, that is to say, for the higher material of some thermal coefficient of expansions, it should be able to guarantee to have between core pipe or plug outer wall and the solar vacuum heat-collecting pipe inwall gap more than 1 millimeter when estimating maximum temperature.The size of this working clearance can design according to the size of solar vacuum heat-collecting pipe inner diameter, can make core pipe or plug account for more than 1/10th of solar vacuum heat-collecting pipe inner capacities as required.Above-mentioned isolation rubber pad should adopt rubber or flexible plastic product to make.
