Air flows through regenerator 12 and enters back into cooler 11 and compression chamber 10 afterwards, to push piston to do work;Preferably, cooler 11
Wall surface temperature be 50-100 DEG C, the air after heat release again flows through the hot electron power generation component and heat after regenerator 12
Chemical heat storage element, meanwhile, it pushes the acting of the piston in expansion chamber 9 and produces electricl energy.Skilled artisans appreciate that
It is, it is preferable that the frequency of oscillation of entire Stirling cycle is maintained at 25-50Hz.
So far, it has been combined attached drawing and describes the technical solution of the utility model, still, those skilled in the art are easy reason
Solution, the scope of protection of the utility model are expressly not limited to these specific implementation modes.Without departing from the utility model
Under the premise of principle, those skilled in the art can make the relevant technologies feature equivalent change or replacement, these change or
Technical solution after replacement is fallen within the scope of protection of the utility model.
