Technical field

The utility model relates to a kind of solar concentrating photovoltaic power generation equipment, relates to a kind of solar modules structure in particular.

Background technology

The solar photovoltaic technology let us has been enjoyed the clean reproducible energy that solar energy gives, and the research and development of high power concentrator generation technology have brought new notion for the photovoltaic generation industry, have reduced the consumption of silicon, have improved generating efficiency.How to promote the conversion efficiency of solar energy; Under the prerequisite of battery inconvenience, improving the delivery efficiency of solar cell, also be the emphasis of present sunlight light collecting device development, but present concentrating to generate power module is the multi-part completed knocked down products; Complex manufacturing technology; Assemble loaded down with trivial detailsly, and the effective light energy source that can't make full use of can't be carried out insulation blocking with receiving units such as solar chips in light harvesting.

The utility model content

The purpose of the utility model is to provide a kind of solar modules structure that has higher light gathering efficiency and can protect receiver assembly.

In order to reach above-mentioned purpose, the solution of the utility model is:

A kind of solar modules structure; Include module casing, Fresnel Lenses group, sunshading board and receiver assembly; The module casing comprises that one is established by the middle part aluminium sheet and the two ends aluminium sheet group of base plate and dual-side sheet metal forming, is equiped with receiver assembly on the base plate of middle part aluminium sheet; The Fresnel Lenses group comprises that a plurality of Fresnel Lenses unit forms array and be positioned module casing top and link to each other with the module box sealing; Sunshading board is fixed in the module casing and is positioned at the top of receiver assembly, and sunshading board is arranged and is provided with light-conductive hole, and the center of light-conductive hole is corresponding to the focus of each Fresnel Lenses unit.

Described receiver assembly includes light funnel, receiver and radiator.

Described receiver comprises DBC substrate, diode, connector and is positioned at the concentrator cell at its center.

The focus of the center of the concentrator cell in the described receiver and the center of light-conductive hole and Fresnel Lenses unit point-blank.

After adopting said structure; When the solar modules of the utility model is worked; Solar radiation on the Fresnel Lenses group of module casing top, the light beam after the focusing through light-conductive hole after direct projection go in the light funnel of receiver assembly, and behind the secondary optics element, get into receiver; The utilization of maximal efficiency effective light, thereby can improve the generating efficiency of module greatly.And sunshading board can prevent to follow the tracks of and plays a protective role when solar irradiation was to lead or other flammable parts when error was arranged, and makes that being positioned at receiver assembly below the sunshading board avoids in light harvesting, receiving solar irradiation and destroy.

Embodiment

In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.

The solar modules structure of the utility model includes module casing 1, Fresnel Lenses group 2, sunshading board 3 and receiver assembly 4.

Module casing 1 comprises a middle part aluminium sheet 11 and two ends aluminium sheet 12 by base plate and dual-side sheet metal forming, and middle part aluminium sheet 11 and two two ends aluminium sheets of being " ㄩ " type are established the formation casing for 12 groups, are equiped with receiver assembly 4 on the base plate 121 of middle part aluminium sheet.The top of module casing 1 is an opening, and opening scioptics bracing frame 13 is installed and is supported with Fresnel Lenses group 2 above module casing 1.Fresnel Lenses group 2 comprises that a plurality of Fresnel Lenses unit 21 composition arrays are positioned module casing top, and module is linked to each other dustproof and waterproof through silica gel strip 5.Sunshading board 3 is fixed in the inside of module casing 1; Be placed with a plurality of light-conductive holes 31 on it; Arranging of light-conductive hole 31 is corresponding with the Fresnel Lenses unit 21 of Fresnel Lenses group 2 array arrangements that are arranged in its top; And the center of light-conductive hole 31 is gone in the light-conductive hole 31 thereby make sunlight see through the 21 focusing back direct projections of Fresnel Lenses unit corresponding to the focus of each Fresnel Lenses unit 21.

Be equiped with a plurality of receiver assemblies 4 on the base plate 121 of module casing 1, this receiver assembly 4 be positioned at each light-conductive hole 31 under, receiver assembly 4 includes light funnel 41, receiver 42 and radiator 43.Light funnel 41 is supported to be fixed in radiator 43 tops through light funnel holder 411, and is equiped with secondary optics element (not shown) in the light funnel 41, like light funnel, glass prism.Receiver 42 is positioned at light funnel 41 belows; The concentrator cell (not shown) that it comprises DBC substrate, diode, connector and is positioned at its center; Thereby the secondary optics element in the light funnel 41 can be realized the light beam after passing through lens and converging to be evenly distributed in the chip surface of the concentrator cell of receiver 42; Because of the upper shed of light funnel 41 corresponding to light-conductive hole 31 belows; And the center of light funnel 41 upper and lower openings and the center of the concentrator cell in the receiver 42 be on same straight line, like this, just can make in the receiver 42 concentrator cell center and light-conductive hole 31 center and Fresnel Lenses unit 21 focus point-blank.

After adopting said structure; When the solar modules of the utility model is worked; Solar modules places sunlight following time, and solar radiation gets into light funnels 41 through the light beam behind the focussing force of each Fresnel Lenses unit 21 through light-conductive hole 31 on the Fresnel Lenses group 2 of module casing 1 top; After evenly distributing through the secondary optics element; Arrive at last on the concentrator cell in the receiver 42 and convert solar energy into direct current, the heat energy that the part sunlight converts into then dispels the heat to air through the radiating fin of radiator 43, effectively reduces battery temperature.Such module body structure design makes the sunlight after focusing on go in the receiver 42 through light-conductive hole 31 direct projections; The utilization of maximal efficiency effective light; Thereby can improve the generating efficiency of module greatly; And light beam is when getting into receivers 42 through light-conductive hole 31, and sunshading board 3 has hidden unnecessary astigmatism, can prevent to follow the tracks of when error is arranged solar irradiation and perhaps play a protective role during other flammable parts to lead; Make the receiver assembly 4 be positioned at sunshading board 3 belows avoid in light harvesting, receiving solar irradiation and destroy, when improving optical efficiency and have an effect of protection receiver assembly.

Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
