Description
Technical field
The invention belongs to technical field of solar water heaters, a kind of roof type oscillation flow heat pipe solar energy water heater particularly is provided.A kind of profile of oscillating flow heat pipe (claiming pulsating heat pipe again) such as efficient natural circulating solar energy water heater on domatic roof of relating to.
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.It is the flat plate collector and the vacuum tube collector of heat-transfer working medium that present two kinds of the most frequently used solar heat collectors are respectively with liquid, and 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: solar heat collector adopts the mode of Natural Circulation usually, and 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 the roof type oscillation flow heat pipe solar energy water heater on a kind of profile such as domatic roof.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, thermal insulation layer 7, shell 8, feedwater, drainage pipeline and connecting pipe.See Fig. 3.
Thermal-arrest plate 1 of the present invention is made up of 3～50 groups of oscillating flow heat pipes, can determine the number of heat pipe according to the building roof area.The fire end of its concrete 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.The domatic roof shape is made on thermal-arrest plate top, and thermal-arrest plate lower knuckle becomes the circular-arc thermal-arrest plate header 2 that enters, and therefore, thermal-arrest plate header is positioned at thermal-arrest plate bottom and is blocked by the thermal-arrest plate, does not influence the attractive in appearance of building roof.After the heat storage water tank 3 that links to each other with thermal-arrest plate header places the thermal-arrest plate equally.
The caliber of oscillating flow heat pipe is 2～5 millimeters of φ, and material is generally copper pipe or other metal tubes, and 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 outer thermal-arrest plate 1 of sun set hot plate header, covering by clear glass steel deck-plate 5, to reach purpose through solar radiation, the environment heat radiation towards periphery of prevention thermal-arrest plate and protection thermal-arrest plate towards sunlight one side.In order to reduce radiation loss, be furnished with thermal insulation layer 7 at the opposite side of thermal-arrest plate, insulating layer material is rock wool, mineral wool or polystyrene.Thermal insulation layer is outward a shell 8, and shell can play protection and the fixedly effect of absorber plate, transparent cover plate and thermal insulation layer.
The thermal-arrest plate of roof type solar water heater arranges towards south (or west), with the inclination angle on roof be 30 °～50 °, or make wavy profile, water heater is fixed on the building roof by corresponding supporting construction.The sun set hot plate absorbs solar radiation, heat is delivered to condensation segment by the oscillating flow heat pipe bringing-up section, the water that heating collector plate case is 2 li, water enters heat storage water tank 3 because of being heated upwards to flow by connecting pipe, the cold water that heat storage water tank is 3 li is heated because of gravitate enters thermal-arrest plate header by connecting pipe, 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 header can place the lower end 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, the present invention is the domatic roof contours, can place on the roof of various flat-tops, has not only beautified facade but also can satisfy the requirement of building energy conservation.
