Description
Technical field
The invention belongs to technical field of solar water heaters, a kind of shading type oscillation flow heat pipe solar energy water heater particularly is provided.A kind of efficient natural circulating solar energy water heater that relates to oscillating flow heat pipe (claiming pulsating heat pipe again).
The critical component of solar water heater is a solar heat collector, and the quality of its performance is to the fine or not decisive role of solar water heater performance.Be that the flat plate collector of heat-transfer working medium and vacuum tube collector are two kinds of the most frequently used solar heat collectors at present with liquid, wherein vacuum tube collector can be divided into glass vacuum pipe heat collector and heat pipe vacuum tube hot collector again.These several solar heat collectors respectively have pluses and minuses, but structurally all have identical defective.Be the mode that common solar heat collector adopts Natural Circulation, water tank must place the upper end, and weight is big, and outward appearance is single, is difficult to combine with architectural appearance.
Oscillating flow heat pipe is a kind of new and effective heat pipe (H.Akachi (barren land): Looped Capillary Tube Heat Pipe that grew up in nearly ten years in the world, Proceedings of 71thGeneral Meeting Conference of JSME, Vol.3, No.940-10,1994).As shown in Figure 1, selfexcited oscillating-flow heat pipe is by the long bending snakelike pipeline of capillary, is made up of some thin straight pipelines and some elbows, is divided into bringing-up section, condensation segment and isolation section three parts.By the difference of its circulatory system, can be divided into loop type (Looped) and the disjunct non-loop type of head and the tail (Unlooped) two kinds that head and the tail are linked to be the closed-loop path again.Described under its operation principle: when enough hour of caliber, under vacuum, be encapsulated in working medium in the pipe will be in pipe the plunger between formation liquid, vapour phase.In bringing-up section, the liquid film between steam bubble or vapour post and the tube wall causes steam bubble to expand because of the constantly evaporation of being heated, and promotes the vapour-liquid plug flow to cold junction condensation contraction, thereby forms bigger pressure reduction between cool and heat ends.Because the vapour-liquid plunger is interspersed, thereby in pipe, produce strong reciprocating vibration motion, thereby realize high efficiencies of heat transfer.
This new heat pipe has following outstanding advantage than conventional heat pipe: caliber is little, and volume is little, augmentation of heat transfer; Do not need capillary wick, simple in structure, cost is low; Reliable, liquid backflow adaptivity is strong, is difficult for dryouting, and starts rapidly; Can be arbitrarily crooked, applied range; Can adopt different mode of heatings and heating location.With oscillating flow heat pipe as the thermal-arrest plate of solar water heater not only collecting efficiency than existing be the solar water heater height of thermal-arrest plate with dull and stereotyped, glass tube with vacuum or conventional heat pipe, but also have the advantage of many uniquenesses, can remedy many defectives of existing solar water heater.
Summary of the invention
The object of the present invention is to provide a kind of shading type oscillation flow heat pipe solar energy water heater.With the thermal-arrest plate of oscillating flow heat pipe as solar water heater, the thermal-arrest plate header that has solved existing natural circulation solar energy hydrophone must place thermal-arrest plate top, and outward appearance is single, is difficult to the problem that combines with architectural appearance.
The present invention includes: oscillating flow heat pipe thermal-arrest plate 1, thermal-arrest plate header 2, heat storage water tank 3, clear glass steel deck-plate 5, absorber plate 6, feedwater, drainage pipeline and connecting pipe.See Fig. 3.
Thermal-arrest plate 1 is made up of 3～15 groups of oscillating flow heat pipes, and the fire end of oscillating flow heat pipe 4 places on the absorber plate 6, and closely contacts with absorber plate, accepts the area of solar radiation with increase.The colling end of heat pipe is placed in the thermal-arrest plate header 2, and thermal-arrest plate header 2 places thermal-arrest plate bottom.Thermal-arrest plate 1 is made shading type profile as shown in Figure 3, and its setting angle can be regulated according to the variation of solar incident angle degree.
The caliber of oscillating flow heat pipe is 2～5 millimeters of φ, and material is generally copper pipe or other metal tubes.The pipe internal pressure is 1 * 10
-1～1 * 10
-2Pa, the working solution of encapsulation is pure distilled water, ethanol or acetone in the pipe.
Be positioned at the thermal-arrest plate 1 that sun set hot plate header absorbs solar radiation outward and coat, to reach through solar radiation, to stop the purpose of environment heat radiation towards periphery of thermal-arrest plate and protection thermal-arrest plate by clear glass steel deck-plate 5.
The sun set hot plate absorbs solar radiation, heat is delivered to the water of 2 li of condensation segment heating thermal-arrest plate headers by the oscillating flow heat pipe bringing-up section, water enters heat storage water tank 3 because of being heated upwards to flow by connecting pipe, 3 cold water is heated because of gravitate enters thermal-arrest plate header by connecting pipe in the heat storage water tank, so forms the course of work of circulation repeatedly.
The present invention has following advantage:
1, the load-bearing requirement of in light weight, the various building roofings that are content with very little.
2, thermal-arrest plate water tank can place the bottom of thermal-arrest plate, and the water tank that does not resemble traditional natural circulation solar energy water heater collector must be placed on the top, has not only reduced difficulty is installed, and has also improved the outward appearance of water heater.
3, because the thermal-arrest plate is not contained recirculated water, thereby be not afraid of winter freezingly, the working solution liquid filled ratio is usually less than 60% in the heat pipe, and constantly vibration thereby heat pipe itself are difficult for breaking, and move quite reliable.
4, oscillating flow heat pipe can be arbitrarily crooked by the requirement of architectural appearance, can be made into the sunshading board or the Sun-shade screen of various different shapings, can reach perfect with architectural appearance and combine.
