Abstract
The utility model relates to a heat increase and reduction dual-purpose solar reflector. A hole or a clamping groove is arranged in the reflector; the reflector is fixed on a heat collecting pipe by a clamping ring through the hole or the clamping groove in the reflector; and the clamping ring and the reflector can rotate around the heat collecting pipe. In the low light in winter, the reflector is arranged below the heat collecting pipe, the front side of the reflector faces the sun and can take effects of gathering light and increasing heat; and in the strong light in summer, the clamping ring and the panel are rotated, so that the panel can be arranged on the lateral surface or the upper surface of the heat collecting pipe to shade part or most part of sunlight on the heat collecting pipe so as to achieve the heat reduction effect.
Description
Technical field
The utility model relates to a kind of Application of Solar Energy technology, particularly utilizes the reflective heat build-up technology of solar energy.
Background technology
Solar energy is a kind of clean environment firendly energy, and various solar water heaters have been come into huge numbers of families.China consumer is the most acceptable at present is direct insertion vacuum tubular glass solar collector, and this solar water heater structure is simple, and cost is lower, stable performance.But owing between this thermal-collecting tube of solar water heater certain clearance will be arranged, add can not thermal-arrest the outer tube thickness of vacuum tube and the thickness of vacuum layer, its actual collector area is about 65%, solar energy runs off about 35%.Cause winter during the low light level, thermal-arrest is not enough, can not make hot water reach desirable temperature.
Summer, solar water heater was assembled great amount of heat during high light, excessive heat energy so that the boiling of the hot water in the water tank.And use during summer hot water less relatively, cause a large amount of hot water wastes.Simultaneously, high-temperature-hot-water amasss for a long time in attemperater, causes the damage of parts easily, shortens the service life of solar water heater.The consumer often uses sunshade net cooling reduction of heat, not only trouble but also inharmonious with construction landscape.
The invention that had has in recent years related to the solar energy reflector, and the brand solar water heater that has has also been used reflector.But these reflectors all are to be fixedly mounted on the rack of solar water heater, and have the cumulative gain of heat effect when daylight is weak winter, and cumulative gain of heat effect is arranged summer equally, the damage of aggravation solar water heater parts.
Summary of the invention
The utility model provide a kind of reflector can be when the low light level light and heat collection, improve the thermal efficiency, again can be when high light heat energy be superfluous the shading reduction of heat, delay the damage of inner water tank and parts, and easy for installation, conversion makes things convenient for.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: make a kind of smooth reflector; When the low light level, it is placed the back of thermal-collecting tube; Reflector just facing to the sun, can reflect the light that sees through from the slit between the every thermal-collecting tube, thermal-collecting tube outer tube glass and vacuum layer and gather on the thermal-collecting tube, improve the thermal efficiency.When summer, high light heat energy was superfluous reflector placed the side or the front of thermal-collecting tube, the back portion of reflector or most ofly make the light diffusion that is mapped to the reflector back side to the space facing to the sun is not directly penetrated on thermal-collecting tube the absorption of minimizing luminous energy.
The reflector of the utility model is with the corresponding thermal-collecting tube of a reflector; The middle and lower part is done the hole that a draw-in groove maybe can pass snap ring respectively on reflector; The hole that snap ring passes reflector is fixed on the thermal-collecting tube, makes it relative fixed and can rotate round thermal-collecting tube again.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structure chart of the utility model.
Fig. 2 is installed in the sketch map of thermal-collecting tube back for the utility model.
Fig. 3 is installed in the sketch map of thermal-collecting tube side for the utility model.
1. glass heat collection tubes among the figure, 2. reflector, 3. snap ring.
The specific embodiment
In Fig. 1, snap ring (3) is fixed on reflector (2) on the thermal-collecting tube (1) through the hole of reflector (2).Reflector can not all around move, but can rotate, and centers on thermal-collecting tube when needing and rotates, and adjusts to suitable position.
When being the gain of heat of the utility model optically focused, Fig. 2 receives the sketch map of illumination.When winter, low light level heat energy was not enough, place the back of thermal-collecting tube to reflector, the sunlight that shines directly into thermal-collecting tube is directly absorbed by thermal-collecting tube; The illumination that sees through gap between the thermal-collecting tube is mapped on the reflector, is absorbed by thermal-collecting tube through reflexing on the thermal-collecting tube; The solar radiation that sees through heat-collecting pipe vacuum layer and thermal-collecting tube outer tube glass is absorbed by thermal-collecting tube through reflection to reflector.
Sketch map when Fig. 3 is the utility model shading reduction of heat.Place reflector during high light the side of thermal-collecting tube summer, and the light that sees through the thermal-collecting tube gap runs off from the gap; The light that sees through the thermal-arrest vacuum layer runs off from the space; The light scattering that shines the reflecting plate back side is run off to the space; The light that shines directly into thermal-collecting tube is absorbed and used.The light of thermal-collecting tube acceptance can be adjusted between 0-100% as required, really accomplishes to use as required the light heat-obtaining.
Claims (1)
1. gain of heat reduction of heat dual-purpose solar reflector; Can be when the low light level light and heat collection again can be when high light heat energy be superfluous the shading reduction of heat; It is characterized in that: the corresponding solar energy heat collection pipe of reflector; Porose or draw-in groove on the reflector, snap ring is fixed on reflector on the thermal-collecting tube through the hole or the draw-in groove of reflector, and reflector can rotate to back, side or the front of thermal-collecting tube around thermal-collecting tube.
