Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
As shown in Figure 1, present embodiment discloses a kind of solar energy high-temperature heat collection pipe 10, it includes glass tube with vacuum 20, the metal heat absorption tube 30 in glass tube with vacuum 20, the reflecting element 40 between glass tube with vacuum 20 and metal heat absorption tube 30 and some connection metal heat absorption tubes 30 and the connection assembly of reflecting element 40；Between metal heat absorption tube 30 and glass tube with vacuum 20, there is toroidal cavity；Metal heat absorption tube 30 is used for allowing heat within it to circulate；Reflecting element 40 for reflexing to metal heat absorption tube 30 by heat, reflecting element 40 is in a tubular form, one side opening of reflecting element 40, so that the heat focused on enters and all projects on endothermic tube 30, is spaced between reflecting element 40 and glass tube with vacuum 20 and between reflecting element 40 and metal heat absorption tube 30 and arranges；Connecting the assembly axis direction interval setting along metal heat absorption tube 30, each assembly that connects includes at least two bracing frame 50.
Reflecting element 40 acts primarily as the function of reflection heat, meanwhile, because the setting of reflecting element 40 and metal heat absorption tube 30 interval, in glass tube with vacuum 20 and the metal heat absorption tube 30 that is not directly contacted with under the condition of high temperature, so reflecting element 40 relative temperature is relatively low, will not deform upon.By connecting assembly, reflecting element 40 and metal heat absorption tube 30 are connected into entirety, add the anti-soft of metal heat absorption tube 30, be possible to prevent metal heat absorption tube 30 deliquescing at high operating temperatures and because gravity or inequality of being heated occur bending and deformation.
Reflecting element 40 is made up of at least one reflective insulation cover 41, it is preferred that reflecting element 40 is made up of at least two reflective insulation cover 41；Being set in distance between reflective insulation cover 41, reflective insulation cover 41 is connected with metal heat absorption tube 30 by bracing frame 50.By interval between reflective insulation cover 41 is arranged, it is possible to prevent between reflective insulation cover 41 to occur because contacting with each other conduction of heat, improves the heat reflection efficiency of reflecting element 40.And the heat that superposition can make metal heat absorption tube 30 radiation produce that repeats of multiple reflective insulation cover 41 is reflected back metal heat-generating pipe more.In the present embodiment, reflecting element 40 is made up of two reflective insulation covers 41, accordingly, each assembly that connects includes three bracing frames 50, one of them bracing frame 50 connects the metal heat absorption tube 30 reflective insulation cover 41 near metal heat absorption tube 30, and two other bracing frame 50 is all connected with metal heat absorption tube 30 and two reflective insulation covers 41.In other embodiments, the concrete condition that the quantity of bracing frame 50, the quantity of reflective insulation cover 41 and bracing frame 50 with which reflective insulation cover 41 connect according to solar energy high-temperature heat collection pipe 10 determines.
The camber line angle of the cross section of reflective insulation cover 41 is between 120 °-300 °.By arranging the camber line angle of the cross section of reflective insulation cover 41 between 120 °-300 °, the heat focused on can be made to be reflected onto endothermic tube in a large number, decrease high-temperature hot loss.Further, the camber line angle of the cross section of reflective insulation cover 41 is between 150 °-240 °.In the present embodiment, the camber line angle of the cross section of reflective insulation cover 41 is 220 °.
The position of the inwall correspondence reflecting element 40 of glass tube with vacuum 20 is provided with heat-reflecting layer 21.Heat-reflecting layer 21 is set by the position of the inwall correspondence reflecting element 40 at glass tube with vacuum 20 so that the heat that metal heat absorption tube 30 radiate can be reflected back toward on metal heat absorption tube 30 more, so that the heat leakage of metal heat absorption tube 30 reduces further.
In the present embodiment, metal heat absorption tube 30 is stainless steel tube.Rustless steel can be attached by welding, therefore it is easy to ensure that the airtight conditions of connecting portion.It addition, stainless steel tube corrosion resistance, excellent strength, use in various fields, easily start with, and the most favourable for cost.Therefore, by arranging metal heat absorption tube 30 for stainless steel tube, it is possible to obtain above-mentioned advantage.Certainly, metal heat absorption tube of the present utility model is not limited only to stainless steel tube, and the metal tube that the material that other heat absorptivities are good is made is also applied for this utility model.
In order to increase the heat absorption speed of metal heat absorption tube 30, in other embodiments, also can arrange some and metal heat absorption tube 30 concentric cannelure on heat-sink shell 31, cannelure is arranged at equal intervals along the axis direction of metal heat absorption tube 30.By arranging some cannelures on heat-sink shell 31, increase the endotherm area of heat-sink shell 31 so that the heat absorption speed of metal heat absorption tube 30 improves the most rapidly.
In other embodiments, in order to make heat reflection part 40 not rock in glass tube with vacuum, the two ends of reflective insulation cover 41 spaced with glass tube with vacuum 20 can be connected with metal heat absorption tube by stainless steel screw, and stainless steel screw is easy to the reflecting element 40 dismounting in glass tube with vacuum 20.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain principle of the present utility model, and can not be construed to the restriction to this utility model protection domain by any way.Based on explanation herein, those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present utility model, within these modes fall within protection domain of the present utility model.
