Abstract
Disclosed is a novel solar energy vacuum heat collecting pipe, which adopts an inner and an outer layers of glass vacuum structure; wherein, the length of the outer pipe is 1.5 m with the diameter of 58 mm; the 150 DEG pipe wall is made into the circular arc mirror surface for inner reflection; while, the length of the inner pipe is 0.8 mm with the diameter of 37 mm; a copper pipe is linked up with the lower end of the inner pipe; low boiling point liquid is filed in the closed copper pipe; the lower end of the copper pipe directly contacts with the upper plane of the PTC materials; the lower plane of the PTC materials contacts with an extraction electrode; the copper pipe is extracted as the other electrode; heat collecting materials are coated on the outer surface of the inner glass pipe and the copper pipe. The utility model has the advantages that the vacuum pipe is large in vacuum layer, low in heat loss, good in temperature preservation performance; the circular arc mirror surface focuses and reflects the sunlight inside and the sunlight directly irradiates the downside surface of the inner glass pipe and the copper pipe so that the heat collecting efficiency can be increased by times; after the copper pipe is heated, the high pressure inside generates high temperature with high heat transfer speed; the PTC material is electrically heated with low power consumption and high heat efficiency, and is saving power, safe and long in service life with the using of the safe voltage.
Description
Affiliated technical field
The utility model relates to a kind of solar vacuum heat-collecting pipe, adopt the structures of direct thermal-arrest, mirror focusing reflection, the transmission of copper pipe Rapid Thermal, PTC auxiliary electrical heating four unifications.
Technical background
The solar vacuum heat-collecting pipe of main flow row all is to adopt inside and outside layer glass vacuum structure at present, outer tube diameter 47mm, and diameter of inner pipe 37mm, outer wall of inner tube coated thermal-arrest material forms.Its shortcoming is that vacuum layer is thin, and heat loss is big, and heat-insulating property is poor, and the speed of interior pipe thermal-arrest and transferring heat energy is slow, all the time according to the time thermal-arrest not.
Summary of the invention
In order to solve existing solar vacuum heat-collecting pipe, thermal-arrest and heat transfer speed are slow, and heat waste is big, the heat-insulating property difference and all the time according to the time defective of thermal-arrest not.The utility model provides a kind of new type solar energy vacuum heat collection pipe, adopts the direct thermal-arrest of glass-tube, mirror focusing reflection, copper pipe thermal-arrest and flash heat transfer and the heating of PTC auxiliary electrical, four unification structures.Overcome the weak point of existing solar vacuum heat-collecting pipe effectively.
Technical solution of the present utility model is: its structure still adopts inside and outside layer glass vacuum structure.Outer pipe range 1.5M, diameter 58mm makes the circular arc minute surface, to internal reflection on the tube wall of its 150 degree; Interior pipe range 0.8M, diameter 37mm; Two pipe upper ends connect, lower end closed, and inside is evacuated, the vacuum layer part, in the pipe lower end be connected copper pipe, copper pipe is that two is big, intermediate elongated twist, copper pipe is totally-enclosed, inside charges into low boiling solution, and the plane directly contacts on copper pipe lower end and the sheet ptc material; The ptc material lower plane contacts with extraction electrode, and copper pipe is made another electrode and drawn.The outer surface coated thermal-arrest material of glass inner tube and copper pipe.
The utility model has the advantages that: the vacuum layer of vacuum tube is big, and heat waste is little, good heat insulating, the circular arc mirror focusing inwardly flashes back the sunlight, the opaco of direct directive inner layer glass tube and copper pipe, Heat-collecting effect multiplication, after copper pipe was heated, internal high pressure produced high temperature, and heat transfer speed is fast.Extraordinary PTC electrical heating, power consumption is little, and thermal efficiency height can voltage safe in utilization, and power saving, safety, life-span are long.
