Abstract
The utility model discloses a flat plate type solar heat collector with high light focusing rate, particularly an improved flat plate type solar heat collector. The improvement is that a cross fin heat collecting pipe and a round evolvent cylindrical surface mirror are adopted to replace a usual flat plate type heat absorbing plate which is combined by pipe sheets. The utility model has the advantages that the utility model can be started under weak solar intensity, and can be used at all seasons; manufacturing cost is reduced, and solar utilization rate is enhanced.
Description
The purpose of this utility model is to improve existing flat-plate solar heat collector.
The purpose of this utility model is achieved in that
A kind of flat-plate solar heat collector of high concentration ratio, it is made up of flat plate collector, water storage tank, support etc.It improves substantially and is: absorber plate in the flat plate collector and comb are that the down either side of cross fin thermal-collecting tube is provided with garden involute cylindrical mirror reflecting plate, its curved surface is towards the longitudinal axis of cross fin thermal-collecting tube, the radius of curvature of reflecting plate by under the cross fin thermal-collecting tube to increasing gradually to its outside, its track is the involute in garden.
The garden involute of the described cylindrical mirror reflecting plate of above-mentioned high concentration ratio flat-plate solar heat collector is to be to decide the garden with cross fin thermal-collecting tube width, with cross fin lower ends end points is the involute starting point in garden, stretch to cross fin thermal-collecting tube left and right sides, the involute cambered surface peak of cylindrical mirror be on the involute of garden with the upper end vertex of cross fin be in same horizontal level a bit.
The flat-plate solar heat collector of above-mentioned high concentration ratio, the number of described cross fin thermal-collecting tube is more than two groups, the garden involute cylindrical mirror starting point of every group of thermal-collecting tube is kissed in twos under the cross finned tube and is connect, the peak of cylindrical mirror joins in twos in the two sides of cross fin thermal-collecting tube, becomes the continuous arc panel.
The utility model is owing to adopt said structure, garden involute cylindrical mirror can reflex to the sunlight that shines on the cross fin thermal-collecting tube effectively, and need not to adopt complicated sunshine tracking device, so both reduced cost, and having improved solar energy utilization rate, the heat production water yield can increase by 20～40%.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is the utility model overall structure front view;
Fig. 2 is an A-A cutaway view of the present utility model;
Fig. 3 is the structure chart of cross fin thermal-collecting tube of the present utility model.
As we can see from the figure, high concentration ratio flat-plate solar heat collector described in the utility model adopts triangular supports 6 to support, water storage tank 2 is arranged at top, flat-plate solar heat collector tilts to place, and flat-plate solar heat collector is made up of transparent cover plate 4, cross fin thermal-collecting tube 3, involute cylindrical mirror 1 and shell 5.Below cross fin thermal-collecting tube 3 and left and right sides be the involute cylindrical mirror reflecting plate 1 in garden.The width that Fig. 3 illustrates the cross finned tube is d, and then the mathematic parameter equation of the involute in garden is
x=d/2(cost+tsint)
y=d/2(sint-tcost)
The starting point 8 that calculates the involute cylindrical mirror in garden thus should be at cross fin thermal-collecting tube 3 former lower extreme points 8, its peak 9 should be at the left and right sides of cross fin thermal-collecting tube 8, distance apart from cross fin thermal-collecting tube 3 center lines is π d/2 place, wherein, d is the width of cross fin thermal-collecting tube 3, and the horizontal level of this peak 9 is mutually neat with the upper extreme point of cross fin thermal-collecting tube 3.
Cross fin thermal-collecting tube can directly pass through water, and heat is directly passed to water, also can make heat pipe, by heat pipe heat is passed to water, and the condensation segment 7 of heat pipe is placed in the water tank 2.
