Wherein, phase before the test carries out nitrogen displacement to the air in system, closes pipe break valve, open aeration valve and
Vent valve starts blower, and nitrogen enters system by aeration valve, after blower pressurizes, into solar simulator, and passes through deflation
Valve drains into outdoor environment, and the air in system is gradually replaced by nitrogen, as oxygen concentration measuring point O2When lower than certain value, complete to set
It changes.
Further, after the completion of displacement, pipe break valve is opened, closes aeration valve and vent valve, system forms closed cycle.
Wherein, for blower for providing the power that nitrogen recycles in system, low temperature nitrogen enters the sun by lamp house import
It in simulator, exchanges heat with xenon lamp unit, temperature increases, and leaves solar simulator by lamp house outlet.
Wherein, impurity of the filter in filter nitrogen avoids causing the component in air cooling system and solar simulator
Pollution.
Wherein, cooling water is led in surface air cooler, for the cooling high temperature nitrogen come out from solar simulator, nitrogen after cooling
It is again introduced into solar simulator by blower, forms closed cycle.
The heat that xenon lamp unit generates is taken away well, is kept away when solar simulator works by cooling system of the invention
Exempt from the generation of ozone, guarantees the safety of personnel and environment.

Specific embodiment
A specific embodiment of the invention is illustrated referring to the drawings, these specific embodiments are only
Illustratively, it is no intended to which any restrictions are carried out to protection scope of the present invention.
Solar simulator structural schematic diagram of the invention, the solar simulator knot in the present invention are shown referring to Fig. 1, Fig. 1
Structure, comprising: lamp house entrance 11, xenon lamp unit 12 and lamp house outlet 13, lamp house entrance 11 can be connected to air cooling system 2 outside, come
Solar simulator 1 is entered by lamp house entrance 11 from the low temperature nitrogen of air cooling system 2, the heat of xenon lamp unit 12 is taken away
Afterwards, solar simulator 1 is left by lamp house outlet 13.
Air cooling system of the invention is as shown in Fig. 2, the air cooling system includes: blower 21, surface air cooler 22, filtering
Device 23, aeration valve 24, pipe break valve 25, vent valve 26 and temperature point T1 and T2, pressure-measuring-point P1 and P2, flow measuring point F,
Oxygen concentration measuring point O2, by pipeline connection, filter 23 passes through pipeline and cuts the lamp house entrance 11 of blower 21 and solar simulator 1
Only the lamp house of valve 25 and solar simulator 1 exports 13 pipeline connections, and table is arranged by pipeline between filter 23 and blower 21
Cooler 22, to form complete air-cooled circuit；Wherein, vent valve 26 is set between lamp house outlet 13 and pipe break valve 25,
Aeration valve 24 is set between pipe break valve 25 and filter 23, and pressure-measuring-point is respectively set in the gas outlet of blower 21 and air inlet
Temperature point T1 and T2 is respectively set at P1 and P2, lamp house entrance 11 and lamp house outlet 13, also divides on lamp house exit and pipeline
It is not provided with oxygen concentration measuring point O2With flow measuring point F.Phase before the test need to carry out nitrogen displacement to the air in system.It closes
Pipe break valve 25 opens aeration valve 24 and vent valve 26, starts blower 21, nitrogen enters system by aeration valve 24, by blower
After 21 pressurizations, outdoor environment is drained into solar simulator 1, and by vent valve 26.Air in system is gradually set by nitrogen
It changes, as oxygen concentration measuring point O21 be lower than certain value when, it is believed that complete displacement.
After completing nitrogen displacement, air cooling system 2 switches to closed cycle.Pipe break valve 25 is opened, aeration valve 24 is closed and is put
Air valve 26.Blower 21 enters sun mould by lamp house import 11 for providing the power that nitrogen recycles in system, low temperature nitrogen
It in quasi- device 1, exchanges heat with xenon lamp unit 12, temperature increases, and leaves solar simulator 1, filter 23 by lamp house outlet 13
It avoids polluting the component in air cooling system 2 and solar simulator 1 for the impurity in filter nitrogen, lead in surface air cooler 22
Cooling water, for the cooling high temperature nitrogen come out from solar simulator 1, nitrogen after cooling is again introduced into the sun by blower 21
Simulator 1 forms closed cycle.
When system enclosed is run, when system pressure P1 and P2 reduction, it can be mended by opening aeration valve 24 into system
Inflated with nitrogen closes aeration valve 24 after the completion of tonifying Qi.It, can be by opening vent valve 26 to logical when system pressure P1 and P2 are excessively high
Air compartment external environment is deflated, and completes to close vent valve 26 after deflating.
