In dish formula Stirling solar heat generating system, Stirling engine is to finish luminous energy to transform to heat energy, and the core component that further transforms to mechanical energy, and heat dump is as one of critical component of solar energy Stirling engine, its effect is to absorb the solar energy that beam condensing unit converges, and be translated into heat energy, then heat energy is passed to smoothly the working medium of the engine of endothermic tube internal flow.Stirling engine working substance is generally the micro-molecular gas such as hydrogen or helium, and in order to improve the heat convection ability between working medium and the endothermic tube, often makes working medium have very high pressure (reaching as high as more than the 12MPa).Hot-end component for heat dump, have that heat flow density is large, the heated part is inhomogeneous, bear the operating characteristics such as HTHP, working environment is very abominable, and the parameters such as focal spot energy-distributing feature that the material of hot-end component, Temperature Field Control, beam condensing unit are produced all have very harsh requirement.
In case because some fault causes engine stop work, the focal spot that needs fast concentrator to be formed is removed from aperture, not so a large amount of luminous energy is incident upon on endothermic tube, and the working medium of endothermic tube inside can not be taken away heat smoothly, to cause the heat dump hot-end component to be rapidly heated, the working medium of Stirling engine generally all is the very little hydrogen of thermal capacitance or helium in addition, hot-end component can be rapidly heated, to cause in a short period of time the temperature of hot-end component to surpass allowable value, even ablate, scrap.What is more important, if working medium is hydrogen, then hydrogen belongs to inflammable gas, in case endothermic tube burns, the high pressure hydrogen in the pipe can spray, and causes serious consequence.
Generally dish formula concentrator is that motor is realized by cover legacy system driving tracking action actuating mechanisms such as decelerators to following the tracks of action day.With respect to ground reference, the pace of change of solar direction is very slow, so the speed ratio of general decelerator is very large, the rotating ratio motor speed of also namely following the tracks of action actuating mechanism is much lower.In case the focal spot that concentrator produces need to be removed from the heat dump aperture, then need long time, even improve the rotating speed of concentrator drive unit, also be difficult in short several seconds, remove, make engine to be in a safe condition fully from the aperture of engine heat dump focal spot.
In emergency circumstances, the luminous energy that just enters fast the heat dump aperture cuts off, makes heat dump to be unlikely to further to heat up and cross cause thermal damage, is the design solar energy Stirling engine, perhaps one of difficult problem of facing of disc type solar energy Stirling heat generating system.
Therefore, how providing a kind of can fast and effeciently cut off the light path that projects on the heat dump, is the important technological problems that those skilled in the art need to solve at present to avoid the overheated solar energy Stirling engine heat dump protective device that burns of heat dump.
