Abstract
A heat collecting tube of solar energy type using double glass vacuum heat tube is featured as applying double glass vacuum tube with high light transmittance as said heat tube, welding a metal heat collecting rib sheet of cylindrical form with evaporation section to form and integral unit at external side of evaporation section on metal heat tube and coating a layer with high absorbance of sunlight on external surface of metal heat collecting rib sheet.
Description
Technical field
The present invention relates to a kind of utilization of solar energy, particularly a kind of double-glass vacuum heat-pipe solar heat-gathering pipe.
Background technology
Cut down the consumption of energy and environmental protection be the hot issue of the whole society; solar energy is a kind of energy of cleaning; the utilization of solar energy is more and more paid attention to by people; vacuum heat-pipe solar heat-gathering pipe is a core component in the solar water heater; its effect is to transmit solar thermal energy, and its performance quality directly influences the service efficiency of solar water heater.Vacuum heat-pipe solar heat-gathering pipe mainly contains two types at present: single glass vacuum heat-pipe solar heat-gathering pipe and double-glass vacuum heat-pipe solar heat-gathering pipe.Single glass vacuum heat-pipe solar heat-gathering pipe be by the heat pipe evaporator section sealing-in that has fin in individual layer glass tube with vacuum pipe because metal and the direct sealing-in of glass, technological requirement height, cost are also high; Double-glass vacuum heat-pipe solar heat-gathering pipe is that the evaporator section with the metal heat pipe is arranged in the tube chamber of all-glass vacuum thermal-collecting tube, scribbles on the outer wall of interior pipe the high coating that absorbs of sunshine, and technology is simple, and cost is low.Therefore solar water heater mostly adopts double-glass vacuum heat-pipe solar heat-gathering pipe at present.In the prior art, owing to scribble on the outer wall of pipe in the all-glass vacuum tube to the high coating that absorbs of sunshine, its heat-transfer path is: the hot glass tube → heat energy of sun lights reaches inner air tube layer → heat energy and reaches fin → heat pipe, and the heat transfer distance is long, and the solar energy utilization ratio is lower.
Summary of the invention
The object of the present invention is to provide a kind of double-glass vacuum heat-pipe solar heat-gathering pipe of novelty, shorten the approach that solar energy transmits in this solar energy heat collection pipe, further improve the utilization ratio of solar energy.
A kind of double-glass vacuum heat-pipe solar heat-gathering pipe, comprise double-glass vacuum pipe 1, between the interior pipe of double-glass vacuum pipe 1 and the outer tube supporting member 2 is housed, its right part covers with end cap 3, metal heat pipe 4, the evaporator section 4a of metal heat pipe 4 is arranged in the cavity of pipe in the double-glass vacuum pipe 1, its condensation segment 4b is positioned at the outside of end cap 3, it is characterized in that: double-glass vacuum pipe 1 adopts the double-glass vacuum pipe of high transmission rate, the outside of metal heat pipe 4 its evaporator section 4a is provided with one and is the columnar collector metal fin 5 of one with evaporator section 4a weldering, on the outer surface of this collector metal fin 5, scribble the high coating that absorbs of sunshine, the diameter of collector metal fin 5 is slightly less than the caliber of pipe in the double-glass vacuum pipe 1, is provided with a supporting member 6 between the interior pipe of collector metal fin 5 and double-glass vacuum pipe 1.
With prior art relatively, advantage of the present invention is: cylindrical metal thermal-arrest fin and metal heat pipe evaporator section are welded as a whole, and insert and manage in the tube chamber in the double-glass vacuum pipe, the diameter of cylindrical metal thermal-arrest fin is slightly less than the caliber of pipe in the double-glass vacuum pipe, high printing opacity double-glass vacuum pipe makes sunshine can see through glass and shines directly on the cylindrical metal thermal-arrest fin, shorten the heat transfer distance, reduced heat loss; Thermal-arrest fin outside wall surface scribbles the coating to the sunshine high-absorbility, and columnar collector metal fin can absorb solar thermal energy 360 ° of scopes, can increase substantially solar absorption efficient.
