Description
Technical field
The present invention relates to a kind of solar energy heating device, especially a kind of hot pipe type self-focusing vacuum heat collection tube belongs to the solar energy utilization technique field.
Background technology
Understand according to the applicant, vacuum heat collection pipe is as the core devices of solar energy heat utilization field, and its major function is to be heat energy with conversion of solar energy.Heat pipe is a kind of high-performance heat transfer components, has characteristics such as efficient height, security performance be good.With hot pipe technique and vacuum heat collection pipe set, make the heat pipe-type metal-glass vaccum heat-collecting tube that can be applicable to medium and high temperature heat utilization place, can improve the heat transfer and the security performance of vacuum heat collection pipe.
What manufacturing heat pipe-type metal-glass vaccum heat-collecting tube need be properly settled is expansion issues.As everyone knows, metal is different with the coefficient of expansion of glass, and therefore after variations in temperature, the swell increment of metal and glass there are differences, and causes metal and glass sealing fracture easily.And the heat pipe bringing-up section top that is inserted in the glass tube is a free end, so avoided two ends through type metal-glass vaccum heat-collecting tube need adopt expansion joint to eliminate the way of swell increment difference, has saved components and parts, has simplified manufacture craft.
Yet the hot pipe type focusing thermal-collecting tube of Shi Yonging all adopts with solar panel the structure of inserting after pre-formed in the glass tube in the market, will vacuumize in the glass tube to prevent heat waste again.Though this focusing solar collector efficient height, complex manufacturing technology, solar panel is put into the glass tube location difficulty.
Summary of the invention
The objective of the invention is to: at the shortcoming that above prior art exists, propose a kind of simple in structure, technology convenient, high efficiency hot pipe type self-focusing vacuum heat collection tube.
In order to reach above purpose, hot pipe type self-focusing vacuum heat collection tube of the present invention comprises that transparent glass tube and bringing-up section are inserted in heat pipe wherein, described heat pipe bringing-up section surface scribbles and absorbs the sunshine coating, form vacuum chamber between described glass tube and the heat pipe bringing-up section, its improvements are: it is the focusing surface that conic section has focusing function that described glass tube is partly made the cross section, described focusing surface is coated reflectorized material, form and focus on reflective surface, the bringing-up section of described heat pipe is placed on the optically focused band of described optically focused reflective surface.
During work, sunshine sees through glass tube and vacuum chamber, the part direct irradiation is scribbling on the heat pipe surface that absorbs the sunshine coating, exhausted big portion is radiated on the heat pipe behind the optically focused reflective surface reflect focalization of glass tube bottom, after sunshine is absorbed the absorption of sunshine coating by the heat pipe surface, working medium in the heating heat pipe pipe, intraductal working medium vaporization back arrives the cooling section of heat pipe, with heat transferred heat pipe cooling medium.After the steam condensation in the cooling section, the bringing-up section of getting back to heat pipe recycles again.
Advantage of the present invention is, owing to rationally utilize glass tube self to form reflective surface, ingenious glass tube and reflective surface united two into one, therefore need not to be provided with in addition solar panel in glass tube, compare with existing internal light-concentrating plate, construction is simple, easy to make, reduced cost.In addition,, can better protection can cut down and the glass interface because interface adds protective cover, more can be high temperature resistant.In a word, total design science, simple, reasonable is convenient to large-scale industrial production, performance safety, reliable, and cost is low, easily promotes.
