Description
Technical field
The utility model relates to a kind of solar battery sheet checkout equipment, particularly relates to a kind of device that keeps the solar simulator light source irradiance stability in the solar battery sheet checkout equipment.
Background technology
Solar simulator is the critical component of solar battery sheet tester normal operation, in the prior art, usually adopts xenon lamp as the light source of solar simulator.Xenon source radiation spectrum energy distribution and meridian sunshine are close, and irrelevant with the variation of xenon lamp power input, spectral power distribution is also almost constant in lifetime, still, colour temperature after xenon lamp is lighted is about 6000K, and environment temperature can have influence on the irradiance stability of xenon lamp output.
Because the solar battery sheet tester in use, the xenon lamp of solar simulator opens and closes frequent, can produce amount of heat at short notice, if poor heat radiation, will affect the irradiance stability of xenon lamp output, thereby directly have influence on solar battery sheet tester measuring accuracy and accuracy, therefore, develop high-quality solar simulator, its heat radiation becomes problem demanding prompt solution.
Summary of the invention
Technical problem to be solved in the utility model is the device that the light source irradiance stability that can keep solar simulator of a kind of compact conformation and excellent in heat dissipation effect is provided for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of device that keeps the light source irradiance stability of solar simulator, include can accommodating light source housing, it is characterized in that: described housing has two the first side wall and the second sidewalls of relatively establishing, wherein, the inboard of described the first side wall is provided with the first fan, the inboard of described the second sidewall is provided with the first heat radiator, the arranged outside of this second sidewall has cooling piece and the second heat radiator, and the outside of described the second heat radiator also is provided with the second fan.
In order further to improve radiating effect, described housing is respectively arranged with heat insulation foam in the outside of described the first side wall and the second sidewall.So enclosure interior and outside mutually separated by heat insulation foam prevents heat diffusion, guarantees that heat can distribute through the second fan.
For installation and the location that makes things convenient for cooling piece, as preferably, the heat insulation foam that is positioned at described the second sidewall outside offers size and the suitable mounting groove of described cooling piece.
As preferably, the top of described housing also is provided with the pcb board that can be electrically connected with described light source.
Compared with prior art, the utility model has the advantage of: adopted the heat sink with heat radiator, cooling piece and fan, prevent that by the first fan effect the enclosure interior local temperature is too high, guarantee the homogeneity of internal temperature, by two heat radiator the dissipation of heat in the housing is gone out again, and by the second fan realization heat radiation acceleration, improve radiating efficiency; Of the present utility model simple in structure, compact, easy for installation, save the space, more be convenient to safeguard.
