Abstract
The utility model relates to a cooling type photovoltaic module, including toughened glass, go up EVA layer, solar cell, EVA layer, backplate and aluminium radiator down, wherein the first five is planted material and lays in order, is a whole through the high temperature lamination, then installs aluminium radiator in the surface of backplate. Aluminium radiator have a cellular texture, the radiator main part is six cuboids, accepts the face with the one side of backplate contact for the heat source, all the other five faces are equipped with a plurality of ventilation holes, the intercommunicating porosity of the hole of establishing for interlocking each other. A plurality of ventilation holes in the aluminium radiator have increased the area of contact of radiator with the air, have promoted photovoltaic module's radiating effect to make the solar cell work in the subassembly promote the output and the conversion efficiency of subassembly in a lower temperature, indirectness.
Description
Technical field
The utility model relates to solar energy materials and devices field, is a kind of heat radiating type photovoltaic module specifically, radiator structure and Components integration is integrated, reach good radiating effect, makes to remain on lower temperature during component operation.
Background technology
Along with traditional fossil energy reduces day by day, constantly aggravate the harm that environment causes, regenerative resource has all been invested sight in countries in the world, wishes that regenerative resource can change the energy resource structure of the mankind, maintains long-range sustainable development.Wherein solar energy becomes the focus that people pay attention to its exclusive advantage.Abundant solar radiant energy is the important energy, is inexhaustible, nexhaustible, pollution-free, cheap regenerative resource.
In the numerous application of solar energy, an application is the most widely photovoltaic generation, and the core component of photovoltaic generation is photovoltaic module, and the elementary cell of photovoltaic module is then solar battery sheet.Traditional photovoltaic module mainly uses toughened glass, EVA(ethylene-vinyl acetate), a backboard and frame entirety that solar battery sheet is packaged into, wherein connect with welding between solar battery sheet, then by convergent belt thereto, the electric energy produced by assembly finally by the connector in terminal box exports.
Existing photovoltaic module operating temperature range is generally-40 DEG C ~ 85 DEG C, and the performance exceeding this temperature range assembly will be subject to larger impact.Particularly when temperature is too high, exceed the limit that component package material bears, the change of modular construction will have been caused, directly cause the damage of assembly.In addition because assembly has negative peak power output temperature coefficient, temperature is higher, and the peak power output of assembly is lower.Therefore how to strengthen the heat-sinking capability of assembly, guarantee that assembly still can normally work in hot environment is solar energy power generating field urgent problem always.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of heat radiating type photovoltaic module, effectively can improve the radiating effect of assembly, the service behaviour of lifting subassembly.
The technical solution of the utility model is: a kind of heat radiating type photovoltaic module, comprise toughened glass, upper EVA layer, solar cell, lower EVA layer, backboard and aluminium radiator, wherein the first five kind material lays in order, as a whole through high temperature lamination, then aluminium radiator is installed on the surface of backboard.
Described aluminium radiator has alveolate texture, and radiator body is six cuboids, and the one side contacted with backboard is thermal source receiving surface, and all the other five faces are provided with multiple ventilation hole, and set hole is interlaced intercommunicating porosity, facilitates transmission and the derivation of heat in assembly.
Fixed by heat conductive silica gel between described aluminium radiator and backboard.
The beneficial effects of the utility model are: by arranging aluminium radiator in photovoltaic component back plate side, and aluminium radiator inside has a lot of staggered ventilation hole, which increase the contact area of radiator and air, the heat produced in assembly can distribute by this kind of structure to greatest extent, thus the radiating effect of photovoltaic module is greatly improved, thus make the solar cell working in assembly a lower temperature, indirectly improve power output and the conversion efficiency of assembly.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is a kind of heat radiating type photovoltaic module structure schematic diagram of the present utility model.
In figure, 1 is toughened glass, and 2 is upper EVA layer, and 3 is solar cell, and 4 is lower EVA layer, and 5 is backboard, and 6 is heat conductive silica gel, and 7 is aluminium radiator, and 8 is ventilation hole.
Embodiment
For understanding technical characteristic of the present utility model and content further, be described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of heat radiating type photovoltaic module, comprises the toughened glass 1 of arranging successively from top to bottom, upper EVA layer 2, solar cell 3, lower EVA layer 4, backboard 5 and aluminium radiator 7.The first five is planted after material lays in order and put into laminating machine, by as a whole for its lamination under vacuum high-temperature.Described aluminium radiator 7 is installed on the surface of backboard, is fixedly connected with between the two by heat conductive silica gel 6.
Aluminium radiator in the present embodiment is rectangular column shape body, and have six faces, the one side wherein contacted with backboard is thermal source receiving surface, is used for accepting from the heat in assembly.All the other five faces are provided with multiple ventilation hole 8, and set hole is the intercommunicating porosity of mutual three-dimensional staggered cross, make column have the surface of alveolate texture.Multiple ventilation holes in aluminium radiator add the contact area of radiator and air, make the heat in assembly to distribute in time in air.Therefore, this aluminium radiator can be issued to good radiating effect in the situation of small volume.
Because aluminium radiator has alveolate texture, thus its density is less, lighter weight, significantly can not increase the own wt of photovoltaic module; Aluminium radiator can also provide certain supporting role to the back side of assembly in addition.In the ordinary course of things, the solar cell in photovoltaic module is higher than ambient temperature about 25 DEG C, and the peak power output due to solar cell has negative temperature coefficient, makes power output under its actual conditions generally lower than the maximum power of standard test condition.Adopt the aluminium radiator in the present embodiment, the working temperature of solar cell can be reduced, realize the significantly lifting of output power of photovoltaic module.
