The discharge of waste residue brings serious destruction to earth environment, and on the other hand, oil, coal, natural gas belong to non-renewable
Primary energy, with the explosive growth of population in the world, it is new renewable that the exhaustions of non-renewable energy resources forces people to seek
Energy utilization technology.Solar energy resources is congenital excellent because its is pollution-free, has a very wide distribution etc. as a kind of clean regenerative resource
Gesture obtains the concern of countries in the world, how to be efficiently new energy field problem encountered place using solar energy resources.With
The continuous improvement of solar photovoltaic power plant technology, and energetically support of the national policy to photovoltaic plant, China ground photovoltaic
Various forms of photovoltaic plants such as power station, roof photovoltaic power station are promoted on a large scale.
There is the generating efficiency that the problem of various can reduce common photovoltaic module in use in photovoltaic plant, 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 excessive influence to component and photovoltaic system of component temperature is one of factor of many influence photovoltaic module generating efficiencies.Generally
In the case of, after the operating temperature designed more than component, component 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.
For the heat-removal modalities of conventional photovoltaic assemblies mainly still by the natural heat dissipation of photovoltaic module, heat dissipation effect is poor at present,
Only a few concentrating component employs radiating fin, but is also only used in the part of component, and heat dissipation effect is not ideal enough.
The content of the invention
The purpose of the present invention：It is the air that the photovoltaic module back side is improved by varying the structure type at the photovoltaic module back side
Flowing velocity, reduces the operating temperature of itself of photovoltaic module, lifts the generating efficiency of photovoltaic module and electric power station system.There is provided one
Kind self radiation type photovoltaic module.
In order to reach foregoing invention purpose, present invention employs following technical scheme：
A kind of self radiation type photovoltaic module, including photovoltaic module body, radiating fin is equipped 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 includes the section of taking out stitches of more longitudinally spaced settings, two it is adjacent take out stitches section it
Between form the heat dissipation cavity of diamond shape, and slot is formed 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 diamond shape, two neighbouring fin lists are made 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 member.
The radiating fin is made of aluminium foil or copper foil.
Traditional photovoltaic module is combined by the present invention with the radiating fin with certain geometric modeling, makes full use of photovoltaic
Inclination angle when component is installed, enables air more quickly to be flowed at the photovoltaic module back side, by varying photovoltaic component back plate
The liquid form of air, reduces the operating temperature of photovoltaic module, improves the generating efficiency of photovoltaic module and electric power station system.

Embodiment
The present invention 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 invention, including photovoltaic module body 5,
The back side of photovoltaic module body is equipped with radiating fin 4.
Photovoltaic module in the present invention includes multiple cell pieces 3, and radiating fin 4 includes multiple fin units, each fin list
Member is correspondingly arranged at the back side of each cell piece.
Each fin unit structure in the present invention is identical, respectively includes the section of taking out stitches of more longitudinally spaced settings, and two adjacent tear open
Between line segment form diamond shape heat dissipation cavity, and longitudinal direction one end formed slot, the other end formed wide opening, horizontal wide opening with
Slot replaces.
The heat dissipation cavity of diamond shape, two neighbouring fin lists are made 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 member.
Radiating fin in the present invention is made 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 each 3 back side of cell piece, 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 is in certain inclination angle, and under irradiation by sunlight, the temperature of module backside can be raised drastically, inclination side of the hot-air along component
To flowing from bottom to top, i.e., the air-flow direction 7 shown in Fig. 2, conventional photovoltaic assemblies by this component form of itself into
Row heat dissipation, heat dissipation 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 power generation 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 spy of radiation fin structure of the present invention
Different property, air enter 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 enter
Speed air flow inside heat dissipation cavity 9, after swiftly flowing air flows through the heat dissipation cavity in cell piece region, through air outflow port
8 outflows, the air into next battery panel region flow into position, the so continuous air flow effect for changing the photovoltaic module back side
Fruit, reduces the operating temperature of photovoltaic module.
