Abstract
The utility model relates to a U venturi tube solar water heater, including vacuum tube, u venturi tube, circulating pump, photocell, heat exchanger, heat storage water tank, support, wherein: many u venturi tubes are established ties and are formed one row of slope setting together, and the vacuum tube slope is invertd in the outside of u venturi tube and is fixed on the support, become slope inversion formula vacuum tube heat collector, and the one end that sets up at the heat exchanger of heat storage water tank the inside is connected through the circulating pump to the output of heat collector, and the other end of heat exchanger is manage and is said and form inversion formula evacuated -tube solar thermal -arrest heat transfer circulation circuit by the input of getting back to the heat collector, constitutes a U venturi tube solar water heater, circulating pump connection photocell. The manufacture craft has been simplified in the port blow -by of vacuum tube, has reduced sealing material, is favorable to reduce cost, adopt a copper pipe to bend to the venturi tube into polyphone shape u in succession, technology is simple and convenient, reduces the welding volume, adopt u venturi tube medium reserves to significantly reduce, start soon, effectively improve collecting efficiency.
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 u shape tube solar water heater, 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 water heater.
The technical scheme realizing above-mentioned purpose is: a kind of u shape tube solar water heater, including vacuum tube, u shape pipe, circulating pump, light cell, heat exchanger, heat storage water tank, support；Wherein: branched u shape pipe is cascaded, and shape is in a row to be obliquely installed, vacuum tube oblique inverted is in the outside of u shape pipe and is fixed on support, become oblique inverted formula vacuum tube collector, the outfan of heat collector connects the one end being arranged on the heat exchanger inside heat storage water tank through circulating pump, the other end of heat exchanger returns to the input of heat collector through pipeline, forming inversion type vacuum pipe solar thermal-arrest recuperated cycle loop, constitute a kind of u shape tube solar water heater, circulating pump 3 connects light cell 4.
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 oblique 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 a copper pipe continuous bend to become series winding shape u shape pipe, simple process, reduce welding capacity；Adopt u shape pipe medium reserves to greatly reduce, start fast, efficiency is greatly improved；Adopt light cell to power to circulating pump, play the effect automatically controlled；The water tank of this water heater is placed in flooring, more safer and attractive in appearance than what be placed in above heat collector.
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, light cell 4, heat exchanger 5, heat storage water tank 6, support 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 u shape tube solar water heater, including vacuum tube 1, u shape pipe 2, circulating pump 3, light cell 4, heat exchanger 5, heat storage water tank 6, support 7；Wherein: branched u shape pipe 2 is cascaded, and shape is in a row to be obliquely installed, vacuum tube 1 oblique inverted is in the outside of u shape pipe 2 and is fixed on support, become oblique inverted formula vacuum tube collector, the outfan of heat collector connects the one end being arranged on the heat exchanger 5 inside heat storage water tank through circulating pump 3, the other end of heat exchanger 5 returns to the input of heat collector through pipeline, forming inversion type vacuum pipe solar thermal-arrest recuperated cycle loop, constitute a kind of u shape tube solar water heater, circulating pump 3 connects light cell 4.The part being in outside vacuum tube between series connection u shape pipe answers lag pipe, and thermal insulation casing before bending u shape pipe, just first should be enclosed within the copper pipe making u shape pipe.Heat transfer medium in this heat collectors for solar water heater is conduction oil or anti-icing fluid.
