Abstract
The utility model relates to a vacuum natural circulation solar heat collecting pipe, which solves the technical problem that cold water and hot water have self circulation liquid level difference, and the heat collecting efficiency of the heat collecting pipe is further improved through using an inner pipe with better heat absorption effect. The heat collecting pipe is composed of an outer layer pipe (1), an inner layer pipe (2), a formation vacuum interlayer (3), flanges (4) which are arranged on the outer layer pipe and the inner layer pipe, a cold water hole (4-1) and a hot water hole (4-2) which are respectively arranged on the flanges (4) and a cold water flow passage (5) which is connected with the inner part of the cold water hole. The utility model is characterized in that the hot water hole (4-2) is provided with a hot water leading out pipe (7), a pipe port of which is higher than the cold water hole (4-1) for a height difference H. As a good choice, the outer pipe (1) is a glass pipe, and the inner pipe (2) is a copper pipe which is provided with a selective coating layer which is arranged on the outside of the inner pipe.
Description
Technical field
The utility model relates to a kind of improvement of solar energy heat collection pipe, specifically is a kind of vacuum Natural Circulation solar energy heat collection pipe.
Background technology
Chinese patent literature CN2591526Y discloses " a kind of multithread road solar vacuum heat-collecting pipe ", it forms vacuum interlayer by glass outer tube and interior pipe, interior pipe has the cross cover plate, hot water or cold water's through hole is arranged on the cover plate, cover plate central authorities have and connect cold water pipe in the cold water hole, cold water cover plate under shed is closely managed end cooling water and is entered, and hot water rises and goes into boiler from the orifice flow of periphery, improves collecting efficiency to solve hot and cold water turbulent flow problem.Because hot and cold water hole does not have tangible difference in height, makes the hot water or cold water lack the liquid level difference of Natural Circulation; Moreover the endothermic effect of glass inner tube is still not ideal enough, has influenced collecting efficiency.
Summary of the invention
The utility model technical issues that need to address are, make the hot water or cold water that the self-loopa liquid level difference be arranged, use endothermic effect better in pipe, further improve the collecting efficiency of thermal-collecting tube.
Vacuum Natural Circulation solar energy heat collection pipe of the present utility model, form vacuum interlayer by outer, inner tube, on two pipes flange is arranged, set up cold water hole and hot water hole on it separately, connect the cold water runner in the cold water hole, it is characterized in that described hot water hole is provided with the hot water delivery line, the delivery line mouth of pipe exceeds height difference H of cold water hole.When thermal-collecting tube was tilting, this height difference H promptly was transformed into hot water or cold water's liquid alternate position spike, and the hot water delivery line directly enters the top of water tank, and the collaborative hot water or cold water of promotion of liquid level difference that it produced and water tank self-loopa is flowed, and further improves collecting efficiency.
As preferably, outer tube is a glass tube, and interior Guan Weiguan is the copper pipe of selective coating in addition, with the endothermic effect of pipe in the further raising.Wherein selective coating is extensive use of in the industry.
Realizing the technical scheme of cold water runner, can be to be inserted with plastic septum in the copper pipe tube chamber is separated into two runners that the bottom communicates, and as preferably, the cold water runner is the cold water pipe near the copper pipe wall, and the cold water hole on the flange (adapts with the cold water pipe position.
There is the retainer ring of band pore and through hole the cold water pipe lower end, can make the projecting end of cold water pipe more stable.Individual height difference H, it directly enters the top of water tank, and the collaborative hot water or cold water of promotion of liquid level difference that it produced and water tank self-loopa is flowed, and further improves collecting efficiency.
The utlity model has simple in structurely, water circulation is more reasonable, effective, the advantage that collecting efficiency is higher.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1;
Fig. 3 is embodiment 2 schematic diagrames;
Fig. 4 is that embodiment 1 uses schematic diagram.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1.See Fig. 1, Fig. 2, the vacuum Natural Circulation solar energy heat collection pipe that this is routine, form vacuum interlayer 3 by pipe 2 in the copper of glass outer tube 1 and pipe tyre selective coating, flange 4 is arranged on two pipes, set up cold water hole 4-1 and hot water hole 4-2 on the flange separately, connect cold water pipe 5 in the cold water hole, cold water hole 4-1, cold water pipe 5 and cold water pipe opening are all near inner tubal wall; Hot water hole 4-2 on the flange is provided with hot water delivery line 7, and the delivery line mouth of pipe exceeds height difference H of cold water hole 4-1.Be with the retainer ring 6 of band through hole 6-1 in the pore of cold water pipe lower end, retainer ring inserts copper pipe with cold water pipe and fixes.
See Fig. 4, the cold water of water tank bottom flows out from the opening of cold water pipe 5 lower ends during use, and through the through hole 6-1 of retainer ring 6, rise in copper pipe 2 slowly in the back that is heated, and entering at last the top of water tank 8 by hot water delivery line 7, the height difference H of two mouths of pipe has formed liquid level difference h.
Embodiment 2.See Fig. 3, this routine thermal-collecting tube mainly is used in large-scale solar water conservancy project journey.The cold water pipe 5 on the flange and the pipe end of hot water delivery line 7 have screw thread, are connected with the front and back thermal-collecting tube with convenient.One group of thermal-collecting tube serial or parallel connection is combined into large-scale water heater, uses the circulating pump forced circulation.
