Abstract
The utility model relates to a basically fixed high power focusing solar heat collector device without the need of tracking the sun at any moment. Heat pipes of the basically fixed high power focusing solar heat collector device are transmeridionally and horizontally placed. A reflective mirror with a parabolic column surface is arranged below the heat pipes. The focal line of the reflective mirror is coincident with the center of a heat collecting pipe. A reflective mirror with a double involute column surface or a reflective mirror with an involute and parabola combined column surface of the heat pipes are arranged above the heat pipes. The basically fixed high power focusing solar heat collector device can rotate around the focal line or other axes which are parallel with the focal line. The sunlight which is reflected by a paraboloid can be ensured to be completely reflected to the heat pipes by rotating the basically fixed high power focusing solar heat collector several times per year. 86% of the sunlight which is received by heat pipe of the solar heat collector is in a tracking mode. The focusing multiple is 23-700.
Description
The utility model relates to a kind of Columnating type solar thermal collector.
Because solar energy disperses, the application of solar energy mainly is confined to the water heater aspect.It is not impossible that solar energy is focused on yet, but because the sun moves, and the focal position can change, and must make solar energy focusing device also change the position, follows the tracks of the sun.Therefore the sun tracker more complicated has limited the utilization of solar energy.
The utility model is exactly a kind of basic fixed, high order focusing will be provided, not need to follow the tracks of the sun at any time and shine the sunlight solar thermal collector suitable with the motion tracking solar heat collector on the solar heat pipe, enlarges the range of application of solar energy.
Sun every day, the track of its scanning moved in south gradually since Winter Solstice from the inswept sky in east orientation west, to the Summer Solstice this sky sweep to the tropic of Capricorn, from day to day sweep gradually then toward north, sweep to the tropic of cancer to Winter Solstice.The earth's core is 46.52 ° to the angle of this two tropic, and the track of scanning moves about 8 ° every month, about weekly 1.8 °, and 0.255 ° of every day.Though the time on daytime has 12 hours approximately, shine upon the main several hrs between 9 o'clock to 16 o'clock of more intense time.According to this characteristic, designing does not here need to follow the tracks of the sun at any time, shines the sunlight solar thermal collector suitable with the motion tracking solar heat collector on the solar heat pipe.
This solar thermal collector is such: be different from general solar thermal collector, the solar heat pipe of this heat collector is wanted the East and West direction horizontal positioned.Below heat pipe, be the parabola cylindrical mirror, face the sun, focal line overlaps with the heat pipe center; Above heat pipe, it is the double involute cylindrical mirror that is close to heat pipe together with heat pipe, wide π times of being about the thermal-collecting tube diameter of mouth, face the parabola cylindrical mirror, the sunlight that is used for reflecting back on the parabola cylindrical mirror all reflexes to heat pipe, and the protection heat pipe thing that do not dropped hits; It can also prevent the empty burning of heat pipe altogether when not needing to use solar energy.Parabola cylindrical mirror and involute cylindrical mirror and heat pipe are an integral body, can be around certain root axle, such as the center line of heat pipe or parallel with it center of gravity line rotation, the seasonal variations of following the tracks of the sun.Can prove, at 9 in the morning to afternoon the strongest 7 hours of 4 sun, shine solar energy on the heat pipe and equal this covering device East and West direction rotation and follow the tracks of at any time 86% of the solar time.
The reflectorized material of reflective mirror generally uses aluminium foil, and base plate is the glass steel or stainless steel.Reflective mirror also can be used chrome-plated material.
Be further described below in conjunction with drawings and Examples.
Accompanying drawing 1 is the embodiment oblique view that is installed on the building top.
Accompanying drawing 2 is the side views that are installed on the embodiment of balcony.
Accompanying drawing 3 is the compound cylindrical mirror side views of involute, parabola.
In the embodiment shown in Figure 1, heat collector is that the East and West direction level is put, and is installed on the building top.1 is solar heat pipe, is positioned on the focal line of parabola cylindrical mirror 2, and 3 is the involute cylindrical mirror of heat pipe 1, and mouthful wide be π times of thermal-collecting tube diameter.Can all reflex on the heat pipe 1 by the one or many reflection of the light that reflects back on the reflective mirror 2 through reflective mirror 3.The inboard of the side of this solar thermal collector is two up-small and down-big plane mirrors 4, is used for the sunlight reflected that will reflect back on the reflective mirror 2 to heat pipe 1 or reflective mirror 3, and reflective mirror 4 also can will be mapped to sunlight reflected above it to reflective mirror 2.In the side of heat collector, it is the arcuate socket in the center of circle that the axle to be parallel to the heat pipe center is arranged, 39 ° of radians--47 °, be used for the north-south and follow the tracks of the angle that the sun is regulated heat collector.
Heat collector shown in the accompanying drawing 1 is together in series, and East and West direction is horizontal, is installed in by rows on the building top, and lithium-bromide solution is heated to through one group or several groups of heat collectors and enters in the lithium bromide refrigerator after temperature required.
In the embodiment shown in Figure 2, heat collector is installed on the balcony in south.1 is solar heat pipe, is positioned on the focal line of parabola cylindrical mirror 2, and 3 is the involute cylinder or the compound cylindrical mirror of involute parabola of heat pipe 1.The inboard of the side of this solar thermal collector is two plane mirrors 4.O is rotating shaft, and K is a moving fulcrum, is used to adjust the position of reflective mirror, aims at the sun.Support OG, the OH of this device supports and tiltedly is pulled in the balcony I side towards south respectively.Water tank P is placed on the balcony I, and the bottom is higher than heat pipe.Water in the water tank flows into heat pipe by flexible pipe L, and the steam that produces in heat pipe enters the cavity of water tank P by flexible pipe M, carries out carbonated drink separation, and water vapour is entered the room by flexible pipe N then, and be used for boiling or wash water, hot water open, or other purposes.
