Various problems occurs in use in photovoltaic plant can reduce the generating efficiency of common photovoltaic module, from
And influence the generated energy of photovoltaic system and the income of power station investor.The design work temperature of photovoltaic module is generally 25 DEG C, light
The volt too high influence to component and photovoltaic system of assembly temperature is one of factor of many influence photovoltaic module generating efficiencies.Typically
In the case of, after the operating temperature designed more than component, assembly temperature often raises 1 DEG C, can all reduce photovoltaic module and power station
The generating efficiency and generated energy of system, in summer high temperature weather, such case can be more obvious.
The heat-removal modalities of current conventional photovoltaic assemblies are mainly or by the natural heat dissipation of photovoltaic module, and radiating effect is poor,
Only a few concentrating component employs radiating fin, but is also only used in the part of component, and radiating effect is not ideal enough.
Utility model content
The purpose of this utility model：It is the structure type by changing the photovoltaic module back side, improves the photovoltaic module back side
Speed air flow, reduces the generating efficiency of the operating temperature of itself of photovoltaic module, lifting photovoltaic module and electric power station system.Carry
For a kind of self radiation type photovoltaic module.
In order to reach above-mentioned utility model purpose, the utility model employs following technical scheme：
A kind of self radiation type photovoltaic module, including photovoltaic module body, radiating fin is provided with the back side of photovoltaic module body
Piece.
The photovoltaic module includes multiple cell pieces, and the radiating fin includes multiple fin units, each fin unit pair
The back side of each cell piece should be arranged on.
Each fin unit structure is identical, respectively including many sections of taking out stitches of longitudinally spaced setting, two it is adjacent take out stitches section it
Between constitute the heat dissipation cavity of rhombus, and form slot in one end of longitudinal direction, the other end forms wide opening, is handed in horizontal wide opening and slot
Replace.
The heat dissipation cavity of rhombus, two neighbouring fin lists are made up of between two or so adjacent fins units two adjacent sections of taking out stitches
It is that wide opening is connected with slot between unit.
The radiating fin is made up of aluminium foil or Copper Foil.
With the radiating fin with certain geometric modeling be combined traditional photovoltaic module by the utility model, makes full use of
Inclination angle when photovoltaic module is installed, enables air more quickly to be flowed at the photovoltaic module back side, by changing photovoltaic module
The liquid form of backboard air, reduces the operating temperature of photovoltaic module, improves the generating efficiency of photovoltaic module and electric power station system.
Brief description of the drawings

Fig. 2 is the side structure schematic diagram of self radiation type photovoltaic module；
Fig. 3 is a structural representation for fin unit.
Specific embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 2, coordinate referring to Fig. 3, self radiation type photovoltaic module of the present utility model, including photovoltaic module body
5, it is provided with radiating fin 4 at the back side of photovoltaic module body.
Photovoltaic module in the utility model includes multiple cell pieces 3, and radiating fin 4 includes multiple fin units, each wing
Blade unit is correspondingly arranged at the back side of each cell piece.
Each fin unit structure in the utility model is identical, respectively including many sections of taking out stitches of longitudinally spaced setting, two-phase
Neighbour takes out stitches and the heat dissipation cavity of rhombus is constituted between section, and forms slot in one end of longitudinal direction, and the other end forms wide opening, laterally wide
Mouth replaces with slot.
The heat dissipation cavity of rhombus, two neighbouring fin lists are made up of between two or so adjacent fins units two adjacent sections of taking out stitches
It is that wide opening is connected with slot between unit.
Radiating fin in the utility model is made up of aluminium foil or Copper Foil.
As shown in figure 1, the radiating fin 4 of self radiation type photovoltaic module is freestanding fin, each fin unit is distributed in
The region at the back side of each cell piece 3, is fixed on photovoltaic component back plate 2 by modes such as structure glue or buckles.In photovoltaic module
The region that backboard 2 has assembly junction box 1 is not provided with radiating fin.
As shown in Fig. 2 self radiation type photovoltaic module in normal work, it is necessary to be fixed on assembly support 6, and with level
Face be in certain inclination angle, under irradiation by sunlight, the temperature of module backside can be raised drastically, hot-air along component inclination side
To flowing from bottom to top, i.e., the air-flow direction 7 shown in Fig. 2, conventional photovoltaic assemblies by this component, enter by the form of itself
Row radiating, radiating effect is not ideal enough, changes the air flow condition at the photovoltaic module back side, the air at the enhancing photovoltaic module back side
Turbulence effects, can substantially reduce the operating temperature of photovoltaic module, improve the generating of photovoltaic module and whole photovoltaic power station system
Efficiency.
As shown in figure 3, when air flows through the radiating fin 4 of photovoltaic module, due to the utility model radiation fin structure
Particularity, air enters heat dissipation cavity 9 by air inflow aperture 10, and the inside dimension of heat dissipation cavity 9 regularly changes, it is possible to increase
