【Abstract】 Starting with the heat balance analysis of the solar cooker, the differential epuation of the unsteady energy transmission of the solar cooker in its working state was established and the dynamic respond of the radiational input of the so- lar cooker device was showed by the solution of epuation. Through the analysis on the solution of the epuation, the calculating formulas of the heat performance pa- rameters were achieved, such as the instanlaneous power, proccess average power. instantaneous effect, and proccess effect. In this paper a reasonable measuring met- hod of the heat performance of solar cooker was also presented, at the same time the characteristic equation of the calorific efficiency could be found with mae- sured resulds,更多还原
