Abstract

The utility model provides a novel tube-in-tube screw solar heat absorbing tube which comprises an inner glass tube, an outer glass tube, a glass tube bracket, a glass tube heat absorbing coating layer. The utility model is characterized in that: the inner glass tube or the metal tube is a sawtooth tube or a spiral tube; and a hollow tube, a sawtooth inner tube strengthen wall, a spiral heart inner tube strengthen wall, and a double layer glass outer tube are arranged. Compared with the prior solar vacuum tube, the novel tube-in-tube screw solar heat absorbing tube reduces the water holding capacity of the tube, enlarges the heating area, improves the heat absorbing capacity under the same condition, the metal screw structure inner tube can still be used even when the tube cracks, the penetrable structure makes the heating fluid avoid mixing flow and solves the progressive heating no reactive power thermal losses problem in the engineering installation and serial connection. The utility model is an upgrading product of the future solar heat absorbing tube.

Description

Novel tube-in-tube saw screw type solar heat absorption pipe

Technical field

The utility model relates to the solar energy vacuum tube of a kind of tube-in-tube sawtooth pattern and spiral-shaped structure.

Background technology

The vacuum tube or the heat pipe of anhydrous conduction that is incubated of leaking water in the solar energy vacuum tube technical products at present all reached the purpose that absorbs solar heat, for people's life has brought convenience, but, therefore can not be issued to the purpose of better fast Absorption solar heat at restrictive condition because that solar energy vacuum tube is subjected to that the restriction of mounting condition can not make pipe is too thick or oversize.

Summary of the invention

The utility model provides the solar energy vacuum tube of a kind of tube-in-tube sawtooth pattern and spiral-shaped structure.The solar energy vacuum tube of this tube-in-tube sawtooth pattern and spiral-shaped structure is socketed in the interior pipe of sawtooth pattern and spiral-shaped structure owing to hollow pipe, the amount of being filled with water reduces about 1/2 or 2/3 than the regular solar pipe amount of being filled with water in the pipe, improve the skin fuel factor that becomes and heated about 1/2 or 2/3 fast, sawtooth pattern and screw type surface texture be its unit are of folded form than the inner tube surface of pipe face structure long-pending increase be twice above, heat is imitated specific energy and is issued to the purpose that absorbs solar heat at double at restrictive condition, doubly part of the solar energy vacuum tube of this tube-in-tube sawtooth pattern and spiral-shaped structure expanding area because the skin fuel factor stack that becomes is absorbed heat increases, the rate of heating improves about more than 70%, reached the purpose that sunlight is in short-term produced hot water.

This tube-in-tube saw screw type solar heat absorption pipe has inner glass tube, outer glass pipe, the glass tube support, the glass tube heat absorbing coating, its feature part is: inner glass tube or metal tube are sawtooth pipe or helix tube, and have additional hollow pipe, pipe reinforced wall in pipe reinforced wall and the heliocentric type in the sawtooth pattern, the double glazing outer tube, the annexation of above-mentioned material is: hollow pipe is socketed in sawtooth pipe or the helix tube, the tooth pitch of sawtooth pipe or helix tube head and the tail successively connects, interior sawtooth pipe or helix tube and outer glass pipe are by the socket of glass tube support hollow, the gateway of interior sawtooth pipe or helix tube is connected with the gateway of outer glass pipe, double glazing outer tube and outer glass pipe are by the socket of glass tube support hollow, sawtooth pipe or helix tube surface in the glass tube heat absorbing coating is coated with and invests

This tube-in-tube saw screw type solar heat absorption pipe has been compared five big advantages with solar energy vacuum tube of the prior art: one, treat the water yield about 1/2 or 2/3 in the tube-in-tube minimizing pipe, improve the skin fuel factor that becomes and heated about 1/2 or 2/3 fast, saw spiral shell structure has enlarged the heating surface area of solar pipe, has increased the caloric receptivity under corresponding conditions.Two, Guan Buhui influences use because of pipe break in the metal saw spiral shell structure.Three, through structure makes and adds hot fluid and stopped the mixed flow phenomenon, has solved the going forward one by one idle thermal losses difficult problem of heating in the project installation series connection.Four, the double-vacuum glass tubular construction has been guaranteed the heat insulating coefficient of vacuum tube.Five, the tempering of the foldable structure of sawtooth pattern and screw type and double-vacuum glass pipe is handled the brokenness that has reduced in using.

This from the above tube-in-tube saw screw type solar heat absorption pipe caloric receptivity is to be determined by the tooth length and the tooth pitch density of the size of hollow pipe and sawtooth pattern and screw type extended area.

The yardstick of this tube-in-tube saw screw type solar heat absorption pipe inner and outer pipes, tooth length and tooth pitch density are fixed according to the different needs amount of processing technology.
