Abstract
The utility model relates to a vacuum tube type heat collector of solar water heater, include that vacuum tube, u venturi tube, circulating pump, heat exchanger, support, medium stream advance house steward, medium outflow house steward, wherein: many u venturi tube parallel connections become one row on medium business turn over house steward, the vacuum tube is invertd in the outside of u venturi tube and is fixed on the support, and medium outflow house steward manage and says that connecting media flows into house steward through the one end of circulating pump connection heat exchanger, the other end of heat exchanger, forms inversion formula evacuated -tube solar thermal -arrest heat transfer circulation circuit, constitutes a vacuum tube type heat collector of solar water heater. The manufacture craft has been simplified in the port blow -by of vacuum tube, has reduced sealing material, is favorable to reduce cost, adopt u venturi tube medium reserves to significantly reduce, start soon, effective heat absorption efficiency that improves.
Description
Technical field
This utility model belongs to Application of Solar Energy field, especially solar thermal collector.
Background technology
All-glass solar vacuum tubular collector, low price, good heat insulation, output temperature is high, but storing substantial amounts of medium in vacuum tube, medium is more many, and stored heat is more many, this results in starting slowly, and the heat stored is not fully utilized, thus reducing collecting efficiency.Having a kind of improvement is arrange copper u shape pipe at the inner tube there of vacuum tube, so, greatly reduces medium storage reserves, owing to u shape pipe is relatively thin, exists for very big space in vacuum tube, and this space is full of air.Now, vacuum tube two kinds of forms are installed, one is vertical, and the mouth of pipe of vertical installation is upwards；Another kind is that horizontal type is installed, and horizontal type is to be horizontally disposed with by vacuum tube, and being usually 25 becomes string, and two row share company's case becomes one group.No matter it is vertical or horizontal type, is required between the mouth of pipe and the u shape pipe of vacuum tube sealing, not so, to produce convection current after the air heats in pipe thus dissipated heat, be substantially reduced efficiency.But this sealing is again relative, because the air of the inside to expand when high temperature produces very big pressure, go out sealing member, outwards breathe out hot-air, contraction of gas during low temperature, form negative pressure, sucking cold air, produce breathing phenomenon, the cold air of suction to be gone to the tail end of vacuum tube and absorb heat, form another expansion, constituting step breathing, losing heat, thus reducing the efficiency of solar heat collector, therefore, also need to improve.
Summary of the invention:
The purpose of this utility model, is in that to provide a kind of solar energy vacuum tube heat collector, is provided with u shape pipe, need not seal between u shape pipe and the mouth of pipe of vacuum tube in the vacuum tube of this heat collector, and the air inside vacuum tube is without convection current.
Realizing above-mentioned purpose technical scheme is: a kind of solar energy vacuum tube heat collector, including vacuum tube, u shape pipe, circulating pump, heat exchanger, support, medium flows to house steward, medium flows out house steward, wherein: branched u shape pipe is also connected on medium turnover house steward and becomes a row, vacuum tube is upside down in u shape tube outside and is fixed on support, medium flows out house steward and connects one end of heat exchanger through circulating pump, the other end of heat exchanger connects medium through pipeline and flows to house steward, form inversion type vacuum pipe solar thermal-arrest recuperated cycle loop, constitute a kind of solar energy vacuum tube heat collector.
Further described the above of u shape pipe is welded with the absorber plate possessing coating for selective absorption.
Operation principle: because vacuum tube is inverted, tail end is upper, and opening is downward, and hot-air is doted on cover by tail end, it is impossible to flowing, and the lower end blow-by of vacuum tube lowers efficiency without producing upper and lower convection current.
Beneficial effect: the port blow-by of vacuum tube, simplifies processing technology, decreases encapsulant, advantageously reduce cost；Adopt u shape pipe medium reserves to greatly reduce, start fast, be effectively improved efficiency.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Shown in figure: vacuum tube 1, u shape pipe 2, circulating pump 3, heat exchanger 4, support 5, medium flow to house steward 6, medium flows out house steward 7.
Detailed description of the invention
The detailed description of the invention of this practicality is described below in conjunction with accompanying drawing 1.
A kind of solar energy vacuum tube heat collector, including vacuum tube 1, u shape pipe 2, circulating pump 3, heat exchanger 4, support 5, medium flows to house steward 6, medium flows out house steward 7, wherein: u shape pipe is also connected on medium turnover house steward and becomes a row, vacuum tube 1 is upside down in the outside of u shape pipe 2 and is fixed on support, medium flows out house steward 7 and connects one end of heat exchanger 4 through circulating pump 3, the other end of heat exchanger 4 connects medium through pipeline and flows to house steward 6, form inversion type vacuum pipe solar thermal-arrest recuperated cycle loop, constitute a kind of solar energy vacuum tube heat collector.Medium flows to house steward 6 and all should be arranged in an incubation chamber with medium outflow house steward 7.
