Abstract
The invention discloses a concave mirror combination type condensing power generation unit. The condensing power generation unit comprises a condenser and a solar receiver, wherein, the condenser is composed of at least one concave mirror array which comprises a bracing frame and a plurality of concave mirrors, and the concave mirrors are compactly arranged on the bracing frame by different inclined angles; due to the position of each concave mirror, the shape and the position of the incident sunlight which is condensed on the outer surface of the solar receiver by the concave mirrors are ensured to be substantially identical with the shape and the position of the outer surface of the solar receiver. The concave mirror combination type condensing power generation unit has low cost, easy fabrication and good weather resistance of a reflection unit, wherein, the condenser is composed of a plurality of concave mirror arrays and easy to be assembled and disassembled, and the required precision of a tracker is not high, which facilitates upgrade and reconstruction of a system.
Description
Technical field
The present invention relates to a kind of solar power generation unit, relate in particular to a kind of combination concentration and power generation unit of concave reflecting mirror.
Background technology
Concentrating solar photovoltaic generating can reduce the photovoltaic generation cost significantly.Along with improving constantly of new and effective concentrator cell efficient, concentrating generating system will be more and more important in the solar energy power generating field.Light-gathering optics has various ways, and main application is parabolic reflector formula point focusing system at present, and the advantage of this system is: can change more high efficiency battery; Light concentrating times is variable; Cost low (the catoptron cost is low, and light concentrating times can be very high, to the demand minimizing of battery).But following shortcoming is arranged also: the one, reflector element is made complicated, the reflector element different parts need be made different moulds, and accuracy requirement is higher, local error, to cause the inhomogeneous of battery surface energy distribution, form focusing and cause receiver to damage on the receiver surface easily, perhaps the excessive receiver that overflows of hot spot reduces generating efficiency and reduce generated energy; The 2nd, to the anti-thick property requirement height of catoptron, to stand outdoor long operation.And the reflecting mirror material that is suitable for work under the outdoor conditions at present involves great expense, and is not suitable for large-scale production to requirement cheaply.
Summary of the invention
Purpose of the present invention is to solve the problems referred to above that prior art exists, provide a kind of cost low, be easy to process, the anti-thick property of reflector element is good, be easy to assemble, tracking accuracy is required not high again combination concentration and power generation unit of concave reflecting mirror.
The object of the present invention is achieved like this: a kind of combination concentration and power generation unit of concave reflecting mirror, comprise condenser and sunlight receiver, described condenser is made up of at least one concave mirror array, described concave reflection lens array comprises support frame and a plurality of concave mirror, a plurality of concave mirrors are compactly arranged of installation on support frame with different inclination angles, the shape the when position of each concave mirror guarantees that its sunshine with incident converges to the sunlight receiver outside surface and the shape and the position basically identical of position and sunlight receiver outside surface.
Described concave reflection lens array also comprises transparent cover plate, and transparent cover plate covers on a plurality of concave mirrors and with support frame and is fixedly linked.
Described a plurality of concave mirror is rectangular block of the same size, and the radius-of-curvature equal and opposite in direction of each concave mirror.
Described a plurality of concave mirror is rectangular block of the same size, and the radius-of-curvature of each concave mirror varies in size.
Described condenser is made up of a plurality of concave mirror arrays, and a plurality of concave reflection lens arrays are the center symmetric offset spread with the receiver central shaft.
The equal and opposite in direction of described a plurality of concave reflection lens arrays.
Varying in size of described a plurality of concave reflection lens arrays.
Combination concentration and power generation unit of concave reflecting mirror of the present invention, concave mirror on its condenser can have identical radius-of-curvature and close physical dimension, in the production run of concave reflection lens array, just only need a kind of mould like this, help reducing cost, meet needs of scale production; Simultaneously the concave reflection lens array by support frame, be installed in a plurality of concave mirrors on the support frame and the transparent cover plate that covers on a plurality of concave mirrors is formed, so just concave mirror in the unit and external environment are kept apart, make it avoid the influence of most of extraneous unfavorable factor, improved the anti-thick ability of whole concave reflection lens array, reduced weatherability requirement to reflecting mirror material, thereby can use more cheap reflecting mirror material, also reach the purpose that reduces cost.And this structure condenser is simple to operate, is easy to install.
