Description
Technical field
The utility model relates to a kind of glass metal seal through type evacuated solar collecting tube.
Background technology
Solar energy is a kind of inexhaustible green energy resource.In solar energy heating utilization, usually adopt heat absorbing element, the radiant energy of solar energy is converted into thermal energy collecting effectively.This solar heat-absorbing component is mainly evacuated solar collecting tube, and evacuated solar collecting tube includes all-glass vacuum thermal-collecting tube and glass-metal vacuum heat collection pipe, glass-metal vacuum heat collection pipe adopts outer surface to be coated with the metal tube of coating for selective absorption as absorber, vacuum technique is adopted to make in vacuum in outer glass pipe and inner metal tube, to reduce hot loss of energy to greatest extent.Absorber has at least one end to stretch out in the outer end of glass tube, to be connected with corresponding heat collector.
Traditional glass-metal sealing by fusing through type solar collector pipe is primarily of pipe composition in outer glass pipe, metal sealing part, bellows, collector metal, for enough light-receiving areas can be had, diameter of inner pipe can not be too small, make to need in interior pipe by medium amount comparatively greatly, therefore can only adopt special focusing arrangement that light cover is improved heat-collecting temperature on inner pipe.
Utility model content
The purpose of this utility model is to provide a kind of glass metal seal through type evacuated solar collecting tube, can when without additional focus reflection device, by reducing interior pipe size and placing reflex plate realizes the raising of heat-collecting temperature between outer tube and interior pipe.
The purpose of this utility model is achieved through the following technical solutions:
A kind of glass metal seal through type evacuated solar collecting tube, the some bellowss comprising outer glass pipe, metal sealing part, collector metal pipe and be built in outer glass pipe, described outer glass pipe two ends are equipped with glass sealing part, this glass sealing part arranges bulge loop, described metal sealing part comprises metal outer ring and metal inner ring integrated with metal outer ring, described metal sealing part to insert on described bulge loop and with bulge loop sealing by fusing; Described collector metal pipe is located in outer glass pipe, and its two ends are passed metal sealing part inner ring and stretched out outer glass pipe; Described bellows-sheathed is on collector metal pipe, and corrugated tube end is fixed with getter, and bellows medial extremity welds with collector metal pipe, and the outboard end of described bellows welds with metal inner ring; Described collector metal tube-surface is coated with selective absorbing layer, is provided with optically focused expelling plate between outer glass pipe inner chamber and collector metal pipe.
The beneficial effects of the utility model are: the caliber decreasing collector metal pipe in thermal-collecting tube, but do not affect light-receiving area, the medium flow through is reduced, improve heat-collecting temperature, decrease the use of material simultaneously, reduce cost in pipe.
