Abstract
The utility model provides a direct-through internal light-focusing glass vacuum solar heat collecting pipe, which comprises a heat collecting pipe outer pipe, a heat absorption pipe, and a hyperboloid reflecting plate. The utility model is characterized in that the glass vacuum solar heat collecting pipe is a direct-through type heat collecting pipe, both ends of which are open. The hyperboloid reflecting plate is arranged in the inner part of a vacuum layer. The utility model has the advantages of high heat transfer efficiency, simple manufacturing process, high operating temperature, etc.
Description
The utility model relates to a kind of glass vacuum solar collector tubes.
Existing glass vacuum solar collector tubes all is an end opening, and the similar vacuum flask of the other end is the same, and inner and outer pipes all at the bottom of the harvest garden, block by interior effective metal clamps.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.
The purpose of this utility model provides a kind of through type internal-concentrator glass vacuum solar collector tubes, has heat transfer efficiency height, quick heating, running temperature advantages of higher.
The technical solution of the utility model is: 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.
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 embodiment 1
Fig. 2 is the A-A profile of the utility model embodiment 1
Fig. 3 is the front view of the utility model embodiment 2
Embodiment 1:
First embodiment of the utility model through type internal-concentrator glass vacuum solar collector tubes 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 minute surface, and hyperboloid intersecting lens 5 is pressed close to the outer surface of endothermic tube 2.Make the through type internal-concentrator glass vacuum solar collector tubes of two end openings thus, the knot mouth width d that connects owing to its two end is the several times of simple glass vacuum solar collector tubes knot mouthful width, so glass knot mouth just can be alleviated 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:
Second embodiment of the present utility model as shown in Figure 3, its basic structure is identical with first embodiment, and its difference is that the endothermic tube 2 of embodiment 2 is made into arc 6 near port.And arc 6 play a part glass spring, the thermal-collecting tube stress of endothermic tube 2 that is in operation because of expanding with heat and contract with cold and producing, owing to arc 6 and the johning knot mouth of thermal-collecting tube two end openings micro-strain all takes place is alleviated, so thermal-collecting tube booster not.
Claims (5)
