Abstract
The utility model relates to a kind of vacuum tube collector, has vacuum tube, thermal-collecting tube group and header; Described vacuum tube is arranged on header, and thermal-collecting tube group is passed in vacuum tube; Described vacuum tube comprises outer photic zone, middle vacuum layer and internal layer photic zone from outside to inside successively; It is characterized in that: described internal layer photic zone is coated with weatherability solar selective absorbing coating on the surface of thermal-collecting tube group.The utility model still can carry out thermal-arrest work after vacuum tube breaks as flat plate collector, and result of use is good, long service life.
Description
Technical field
The utility model relates to Application of Solar Energy field, particularly a kind of vacuum tube collector.
Background technology
Solar thermal collector can be divided into vacuum tube collector and flat plate collector according to profile.Vacuum tube collector carries out thermal-arrest by many vacuum tubes, and flat plate collector carries out thermal-arrest by collecting plate.All solar selective absorbing coating can be used in two kinds of heat collectors.Because the sealing of vacuum tube pipe is relatively good, therefore its solar selective absorbing coating adopted is the poor coating of weatherability (as aluminium-aluminium nitride-aluminium).After vacuum tube in use breaks, due to its weatherability poor very easily oxidized, be corroded, therefore directly affects result of use and the service life of heat collector.
Utility model content
The purpose of this utility model is to provide a kind of vacuum tube collector can worked as flat plate collector and use after vacuum tube breaks.
The technical scheme realizing the utility model object is: the utility model has vacuum tube, thermal-collecting tube group and header; Described vacuum tube is arranged on header, and thermal-collecting tube group is passed in vacuum tube; Described vacuum tube comprises outer photic zone, middle vacuum layer and internal layer photic zone from outside to inside successively; Described internal layer photic zone is coated with weatherability solar selective absorbing coating on the surface of thermal-collecting tube group.
Above-mentioned weatherability solar selective absorbing coating is titanium oxynitrides absorber coatings.
Certainly, above-mentioned weatherability solar selective absorbing coating also can be nitrogen chromium oxide absorber coatings.The solar selective absorbing coating of other weatherabilities is also suitable for.
The utility model has positive effect: the coating of weatherability difference in traditional vacuum tube is replaced by weatherability solar selective absorbing coating by (1) the utility model, can after vacuum tube breaks, heat collector still can use as flat plate collector, ensures result of use and service life; (2) in the utility model, weatherability solar selective absorbing coating can be titanium oxynitrides absorber coatings or nitrogen chromium oxide absorber coatings, and such absorber coatings has good weatherability, after vacuum tube breaks, still can carry out thermal-arrest work.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of vacuum tube in the utility model.
Detailed description of the invention
(embodiment one)
See Fig. 1 and Fig. 2, the utility model has vacuum tube 1, thermal-collecting tube group 2 and header 3; Described vacuum tube 1 is arranged on header 3, and thermal-collecting tube group 2 is passed in vacuum tube 1; Described vacuum tube 1 comprises outer photic zone 11, middle vacuum layer 12 and internal layer photic zone 13 from outside to inside successively; Described internal layer photic zone 13 is coated with weatherability solar selective absorbing coating 4 on the surface of thermal-collecting tube group; Described weatherability solar selective absorbing coating 4 is titanium oxynitrides absorber coatings.
(embodiment two)
In the utility model, weatherability solar selective absorbing coating 4 is nitrogen chromium oxide absorber coatings.Other are identical with embodiment one.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
