Abstract
The utility model discloses an efficient solar vacuum heat collecting tube, which solves the problems of slow fluid heat conduction, more heat loss and the like in the prior art. The solar vacuum heat collecting tube consists of a cylindrical outer tube and a cylindrical inner tube; the outer tube and the inner tube are in vacuum seal at an upper end opening; vacuum is between the outer tube and the inner tube; the inner lower end of the outer tube is provided with a bracket for supporting the inner tube; and the cross section of the inner tube is crescent or semi-annual. A heat absorption coating is at least coated on the outer surface of a side wall on one side of a large circular arc of the inner tube. In the structure, the fluid in the solar vacuum heat collecting tube can be greatly reduced by changing the shape of the inner tube without reducing a heating area or increasing the cost of raw materials, so the solar vacuum heat collecting tube greatly quickens the speed of heat conduction, reduces heat loss, has simple integral structure and is convenient to use and process.
Description
Technical field
The utility model relates to a kind of high-efficiency solar vacuum heat collection pipe.
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 high-efficiency solar vacuum heat collection pipe.
For achieving the above object, the utility model high-efficiency solar vacuum heat collection pipe, form by pipe in tubular outer tube and the tubular, 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 cross section of described interior pipe is a crescent or semi-circular.
Further, at least in described the sidewall outer surface of pipe orthodrome one side be coated with heat absorbing coating.
In the said structure, by changing interior tube shape, can not reduce heating surface area and not increase under the situation of the cost of raw material, 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.
Description of drawings
Fig. 1 is that the utility model high-efficiency solar vacuum heat collection pipe is installed in the structural representation on the solar water heater.
Fig. 2 is the cross-sectional schematic of the utility model high-efficiency solar vacuum heat collection pipe one embodiment.
Fig. 3 is the cross-sectional schematic of another embodiment of the utility model high-efficiency solar vacuum heat collection pipe.
Fig. 4 is a perspective view embodiment illustrated in fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 4, the utility model high-efficiency solar vacuum heat collection pipe, form by pipe 2 in tubular outer tube 1 and the tubular, described outer tube 1 and interior pipe 2 are in the vacuum seal of upper end open place, part 3 between outer tube and the interior pipe is a vacuum, the support of pipe in the lower end is provided with and supports in outer tube, the cross section of described interior pipe 2 is a crescent or semi-circular.This structure can not reduce under the situation of heating surface area substantially, 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.
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, adding man-hour, the spacing between the inwall of orthodrome sidewall and roundlet arc sidewall can be as required and processing technology between 1 millimeter to 2 centimetres, select to make.
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.
In summary, high-efficiency solar vacuum heat collection pipe of the present utility model, by changing interior tube shape, can be under the situation that does not reduce heating surface area, fluid in the minimizing solar vacuum heat-collecting pipe that can be a large amount of, thus heat conducting speed accelerated greatly, reduced heat waste, overall structure is simple, uses easy to process.
More than; it only is preferred embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
