Abstract

The invention provides optically focused complete glass vacuum sun thermal-collecting tube in a kind of novel through type, comprise thermal-collecting tube outer tube, endothermic tube, hyperboloid reflecting plate, described glass vacuum solar collector tubes is that the hyperboloid reflecting plate has been placed in the through type thermal-collecting tube and the vacuum layer inside of two end openings, makes the special-shaped ball of outside protrusion on the glass tube of described endothermic tube.This solar collector pipe has multiple advantages such as heat transfer high efficiency, technology are simple, running temperature height.

Description

Optically focused complete glass vacuum sun thermal-collecting tube in the through type
Technical field
The present invention relates to a kind of complete glass vacuum sun thermal-collecting tube.
Background technology
Existing complete glass vacuum sun thermal-collecting tube all is an end opening, and the similar vacuum flask of the other end is the same, and inner and outer pipes is the harvest round bottom all, and interior effective metal clamps is blocked.Water in the endothermic tube is done free convection by upper and lower temperature difference and is conducted heat.Water in this thermal-collecting tube pipe can not circulate and conduct heat.So there are the shortcomings such as design and installation that heat transfer efficiency is low, thermal capacity is big, operating temperature is low and be unfavorable for central heating systems in it.
Summary of the invention
The purpose of this invention is to provide optically focused complete glass vacuum sun thermal-collecting tube in a kind of through type, have heat transfer efficiency height, quick heating, running temperature advantages of higher, and can prevent booster.
Technical scheme of the present invention is: optically focused complete glass vacuum sun thermal-collecting tube in a kind of through type is provided, comprise outer tube, endothermic tube, hyperboloid reflecting plate, described endothermic tube is the through type glass tube of two end openings, the outer surface of endothermic tube scribbles heat-sink shell, the hyperboloid reflecting plate is placed at the back side at described endothermic tube, makes the special-shaped ball of outside protrusion on the glass tube of described endothermic tube.
In through type of the present invention in the optically focused complete glass vacuum sun thermal-collecting tube, 1, the diameter of the outer tube of glass heat-collecting vacuum tube is than the big several times of interior pipe (endothermic tube), outer tube and interior pipe two end openings be connected to beading.2, the camber reflection plate of optically focused is placed in the vacuum layer at the endothermic tube back side.3, the outer surface of endothermic tube scribbles heat-sink shell.4, outer tube and interior pipe (endothermic tube) are the glass tube of coaxial line.
Implement optically focused complete glass vacuum sun thermal-collecting tube in the through type of the present invention, have following beneficial effect: the surface that sunshine all reflexes to endothermic tube is absorbed and transfers heat energy to, thermal-collecting tube is in operation, the stress of endothermic tube because of expanding with heat and contract with cold and producing, alleviated owing to micro-strain all takes place for the connector of special-shaped ball and thermal-collecting tube two end openings, so thermal-collecting tube booster not.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is the front view of the embodiment of the invention 1.
Fig. 2 is the A-A profile of the embodiment of the invention 1.
Fig. 3 is the front view of the embodiment of the invention 2.
The specific embodiment
Embodiment 1:
First embodiment of optically focused complete glass vacuum sun thermal-collecting tube in the through type of the present invention as shown in Figure 1 and Figure 2 comprises outer tube 1, endothermic tube 2, vacuum layer 3, hyperboloid reflecting plate 4, the hyperboloid intersecting lens 5 of thermal-collecting tube.
The opening of thermal-collecting tube two ends is the beading knot mouth of outer tube 1 and endothermic tube 2, and the outer surface of endothermic tube 2 scribbles heat-sink shell.Because flowing water capable of circulation and other heat transfer liquids also can insert metallic conduit in thermal-collecting tube two end openings, the pipe of endothermic tube 2.The concave surface of hyperboloid reflecting plate 4 is made face, and hyperboloid intersecting lens 5 is pressed close to the outer surface of endothermic tube 2.Make the interior optically focused complete glass vacuum sun thermal-collecting tube of through type of two end openings thus, because the knot mouth width d that its two end connects is the several times of simple glass vacuum solar collector tubes knot mouthful width, do small distortion so allow glass knot mouth, thereby just can alleviate the stress that endothermic tube 2 produces because of expanding with heat and contract with cold.Therefore guaranteed the thermal-collecting tube not booster that is in operation.
S1, S2, S3 represent that different angles penetrate the sunshine in hyperboloid reflection 4, because the optically focused effect, the surface that sunshine all reflexes to endothermic tube 2 is absorbed and transfers heat energy to.
Embodiment 2:
The second embodiment of the present invention as shown in Figure 3, its basic structure is identical with first embodiment, and its difference is to make on the glass tube of endothermic tube 2 of embodiment 2 the special-shaped ball 6 of outside protrusion.Abnormity ball 6 plays a part glass spring, and thermal-collecting tube is in operation endothermic tube 2 because of the stress of the generation of expanding with heat and contract with cold, and is alleviated owing to micro-strain all takes place for the connector of special-shaped ball 6 and thermal-collecting tube two end openings, so thermal-collecting tube booster not.
