Abstract
The utility model relates to a U venturi tube solar collector, including vacuum tube 1, u venturi tube 2, circulating pump 3, heat exchanger 4, support 5, wherein: the mouth of pipe of vacuum tube is downward, inverts in the outside of u venturi tube, fixes on support 5, many u venturi tubes are established ties together, become serial -type U venturi tube solar collector, and the one end of heat collector joins heat exchanger 4's one end through the circulating pump, and heat exchanger 4's the other end is manage and is said and constitute U venturi tube solar collector thermal -arrest heat transfer circulation circuit by the other end that joins the heat collector. The mouth of pipe of vacuum tube is downward, and the hot -air of the inside is shrouded by the tail end of vacuum tube, can not produce the convection current, and it is sealed that the mouth of pipe need not be rigorously enforced, only keep warm on exerted copper pipe, need not use the binding case, all u venturi tubes both saved labour with a reduction welding volume that thin copper pipe bending is as an organic whole, very big, can ensure the quality of products again.
Description
Technical field
This utility model belongs to Application of Solar Energy field, especially solar thermal collector.
Background technology
All-glass vacuum tube, low price, good heat insulation, output temperature is high, only produces hot water, and purposes is little, if being used for producing steam and electricity steam boiler complementary application, becomes industrial energy, and purposes is the broadest.But, the swallow vapour producing more than 120 degree need to make medium with conduction oil, and the inner tube capacity of vacuum tube is big, need to be with a lot of conduction oils, and this will increase the biggest installation cost；Further, the conduction oil quantity of heat storage in pipe is also big, and it is long that this results in the starting time；The heat energy stored finally is not fully utilized, and causes efficiency to reduce.For improving this situation, people arrange heat pipe or u shape pipe at the inner tube there of vacuum tube, so, it is accomplished by between the mouth of pipe of vacuum tube and heat pipe or u shape pipe sealing, not so, convection current is the most constantly produced and dissipated heat after air heats in pipe, thus be substantially reduced efficiency, but this sealing is again relative, because the air of the inside to expand when high temperature produces the biggest pressure, go out sealing ring, outwards exhalation, volume contraction during low temperature, form negative pressure, suck air, produce breathing phenomenon, lose heat, thus reduce efficiency, therefore, also need to improve.
Summary of the invention:
The purpose of this utility model, is to provide a kind of u shape tube solar heat-collecting device, and the mouth of pipe of this u shape tube solar heat-collecting device need not seal, and the air inside vacuum tube also will not convection current.
Technical scheme: for achieving the above object, this utility model devises a kind of u shape tube solar heat-collecting device, and it includes vacuum tube, u shape pipe, circulating pump, heat exchanger, support；Wherein: the mouth of pipe of vacuum tube is downward, is upside down in outside the outside of u shape pipe, is fixed on above support；Many u shape pipes are cascaded, become tandem u shape tube solar heat-collecting device, one end of heat collector is attached to the other end of heat collector through one end of circulating pump connected heat exchanger, the other end of heat exchanger through pipeline, constitutes solar thermal collector thermal-arrest recuperated cycle loop.
It is further a piece of aluminium sheet with coating for selective absorption of welding or copper coin on described u shape pipe.
Beneficial effect: the 1. mouth of pipe of vacuum tube is downward, and the hot-air of the inside is shrouded by the tail end of vacuum tube, will not produce convection current, therefore need not strict sealing；2., only it is incubated on the copper pipe exposed, is not required to linking case；The most all of u shape pipe can use a thin copper pipe bending forming to be integrated, and is significantly reduced welding capacity, both saving of labor, can guarantee that again quality.
Accompanying drawing explanation
Fig. 1 is this utility model, the schematic diagram of a kind of u shape tube solar heat-collecting device.
Shown in figure: vacuum tube 1, u shape pipe 2, circulating pump 3, heat exchanger 4, support 5.
Detailed description of the invention
The detailed description of the invention of 1 this practicality of explanation below in conjunction with the accompanying drawings.
This utility model is a kind of u shape tube solar heat-collecting device, and it includes vacuum tube 1, u shape pipe 2, circulating pump 3, heat exchanger 4, support 5；Wherein: the mouth of pipe of vacuum tube is downward, is upside down in the outside of u shape pipe, is fixed on above support 5；Many u shape pipes are cascaded, become tandem u shape tube solar heat-collecting device, one end of heat collector is attached to the other end of heat collector through one end of circulating pump connected heat exchanger 4, the other end of heat exchanger 4 through pipeline, constitutes u shape tube solar heat-collecting device thermal-arrest recuperated cycle loop.
First making a thin copper pipe the longest, measured size on thin copper pipe, the exposed parts at the mouth of pipe overlaps muff respectively, then, it is curved, is fabricated to the u shape pipe that multiple series connection is in a row, u shape pipe is leaned against on support, then vacuum tube cage in the outside of u shape pipe and is fixed on support.
If welding a piece of aluminium sheet with coating for selective absorption or copper coin on each u shape pipe, then collecting efficiency is higher.
