Abstract
The utility model provides a new light condensation and glass vacuum type solar energy heat collector which comprises a heat collector outer sphere, a heat absorption tube of the heat collector and a hyperboloid baffle board. The outer tube of the heat collector is coaxial with the inner tube. The utility model is characterized in that: compared with the prior glass vacuum type solar energy heat collector, the utility model increase the space of vacuum layer and the hyperboloid baffle board is arranged in the vacuum layer. The cross section curve of the hyperboloid baffle board is a circular arc line or combined curve of a circular arc line and an elliptical arc line. The solar energy heat collector has the advantages of high heat efficiency, simple art, low cost and no accumulated dust at glisten board.
Description
The utility model relates to a kind of glass vacuum heat collection tube of solar energy.The skin of glass vacuum heat collection tube of solar energy is a transparent glass tube, and the surface of inner layer glass tube scribbles heat-sink shell, and the inside and outside layer of thermal-collecting tube is coaxial pipe.
Existing glass vacuum heat collection tube of solar energy major part is not a light-focusing type, also have the solar panel that is partly adopted be external nineteen seventies the cross section of utility model be the solar panel of compound parabolic (the compound composition of involute and parabola), place it in the outer below of thermal-collecting tube.Because of easy dust stratification is difficult for again washing so efficient is not high.As the composite parabolic solar panel is placed on inner and outer pipe coaxial thermal-collecting tube in, Gu the characteristic of its cross section curve decision is difficult to reach optically focused ratio preferably.As place it in the inner and outer pipe out-of-alignment thermal-collecting tube, this brings very big difficulty for the making of glass heat-collecting vacuum tube.Because the curvature difference of the every bit of compound parabolic, therefore the manufacture craft required precision of this solar panel is very high in addition.As forming,, put into thermal-collecting tube inside and when glass tube is made, be out of shape or melt because of high temperature though can reach precision with plastics.In addition, make with the sheet metal punching press as the composite parabolic solar panel, the elastic force of metal makes the width of solar panel increase when solar panel leaves mould, inserts the curved surface that is difficult to recover intrinsic composite parabolic in the outer layer glass tube again.
The shortcoming of above-mentioned existing glass heat-collecting vacuum tube is: (1) some sunshine can not be utilized owing to reflex to environment space.(2) since reflecting plate below thermal-collecting tube, easily dust stratification and don't easy cleaning and cause reflection efficiency low, thus influence the thermal efficiency of thermal-collecting tube.(3) complex manufacturing technology, spotlight effect are undesirable.
The purpose of this utility model is: a kind of converging vacuum glass soalr energy heat-collecting pipe of novelty is provided, has collecting efficiency height, reflector not dust stratification dirt, multiple advantages such as manufacture craft is simple, spotlight effect good, cost is low.
The technical solution of the utility model is: (1) enlarges the space of vacuum layer.Thermal-collecting tube internal layer and outer field spacing have promptly been strengthened.(2) the light collecting reflecting plate of the hyperboloid of particular design is placed in the vacuum layer of thermal-collecting tube, and the minute surface of reflecting plate upwards.The sunlight of different angles directive hyperboloid reflecting plate is all absorbed by endothermic tube through reflection.The gap that the solar water heater that converging vacuum glass soalr energy heat-collecting pipe of the present utility model is formed is arranged between the thermal-collecting tube in a row is little.(3) cross section curve of hyperboloid reflecting plate is that circular arc line or most circular arc line become with oval camber line complex group.Hyperboloid intersection and vacuum tube axially parallel are also pressed close to the endothermic tube outside.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the front view of the utility model solar energy heat collection pipe embodiment 1;
Fig. 2 is the vertical view of the A-A section of the utility model solar energy heat collection pipe embodiment 1.
Fig. 3 is the vertical view of the A-A section of the utility model solar energy heat collection pipe embodiment 2.
Fig. 4 is the front view of the utility model solar energy heat collection pipe embodiment 3.
Embodiment 1:
First embodiment of the utility model converging vacuum glass soalr energy heat-collecting pipe as shown in Figure 1 and Figure 2 comprises hyperboloid reflecting plate 1, endothermic tube 2, vacuum layer 3, thermal-collecting tube skin 4, hyperboloid intersecting straight lines 5.
The cross section of hyperboloid reflecting plate 1 is two circular arc lines.Hyperboloid intersecting straight lines 5 is parallel to the axis of thermal-collecting tube, and the hyperboloid intersecting straight lines is pressed close to the outside, below of endothermic tube 2.0 is the concentric circles center of circle of the inside and outside layer of thermal-collecting tube; 0 ' be the left circular arc line center of circle of hyperboloid reflecting plate 1 cross section, 0 " be the right circular arc line center of circle, two centers of circle are all dropped in the circumference of endothermic tube 2 and are symmetry axis with hyperboloid intersecting straight lines 5.Dotted line is represented the radius of two circular arcs, and the radius of two circular arcs equates.The concave surface of hyperboloid reflecting plate 1 is made minute surface, and hyperboloid reflecting plate 1 available metal plate stamping is made.The width of hyperboloid reflecting plate 1 equals the internal diameter of thermal-collecting tube skin 4.Because the cross-section curve of hyperboloid reflecting plate 1 is the circular arc line of two symmetries, so after inserting thermal-collecting tube skin 4, because of the hyperboloid reflecting plate 1 of metal elastic force broadening just recovers intrinsic curved surface.

3The expression different angles are penetrated the sunshine at hyperboloid reflecting plate 1, and the sunshine of shooting down on endothermic tube 2 surfaces is all absorbed by endothermic tube.Because center of circle o ', the o of circular arc line " in the circumference of endothermic tube 2, are absorbed so penetrate the surface that sunshine on the hyperboloid reflector of endothermic tube 2 both sides all reflexes to endothermic tube 2 to the inside.
Embodiment 2:
The utility model second embodiment as shown in Figure 3, basic structure is identical with first embodiment, and its difference is that the cross section of the hyperboloid reflecting plate 1 of embodiment 1 is that two circular arc lines link composition.And the cross-section curve of implementing 2 hyperboloid reflecting plate 1 is by most circular arc line and the compound curve of forming of little part ellipse.Be oval camber line at the little part curve near hyperboloid intersecting straight lines 5 as seen from Figure 3, all the other are circular arc line.
Embodiment 3:
The utility model the 3rd embodiment as shown in Figure 4, basic structure is identical with embodiment 1, embodiment 2, its difference is that the solar energy heat collection pipe of embodiment 1, embodiment 2 is unidirectional opening, and the converging vacuum glass soalr energy heat-collecting pipe of embodiment 3 is two-way opening (being through type).At present can only produce all transparent through type glass-vacuum tube of ectonexine on the market, this pipe itself can not thermal-arrest.
Solar energy heat collection pipe of the present utility model is owing to adopted interior solar panel, and the width d of the binding mouth of endothermic tube 2 and skin 4 is more than 5 times of simple glass vacuum solar heat-collecting pipe.Thereby endothermic tube 2 variation of expanding with heat and contract with cold linking that a mouthful place is alleviated booster not.
This kind thermal-collecting tube can singly prop up or some series connection, is enclosed within the outside of metallic water pipe, and obtains the steam of high temperature and higher water temperature is used for solar electrical energy generation, solar airconditioning refrigeration, solar heating.Also can be used for solar water has a bath.
