Abstract
The invention relates to a thermal power generating method, which leads the thermal power generation to be used in any scope and any temperature condition. The invention is characterized in that a thermotube is arranged between a thermal source and a cold source; a thermotube heat absorption end, a thermotube deformation section and a thermotube heat release end are arranged on the thermotube; the thermotube heat absorption end is connected to the thermal source; the thermotube heat release end is connected to the cold source; a hot junction valve is arranged between the thermotube heat absorption end and the thermotube deformation section; a cold junction valve is arranged between the thermotube heat release end and the thermotube deformation section; a certain end or two ends of the thermotube deformation section are connected with piezoelectric material to form a power generation part; a power displacement stopper mechanism used for limiting the stretching of the power generation part is arranged outside the power generation part, so as to form pressure to the piezoelectric material; the invention has the expansion power generation process that the cold junction valve is closed and the hot junction valve is opened to lead the thermotube deformation section to expand, thus the piezoelectric material is pressed to output the current with a certain polarity (such as positive current); the invention has the contraction power generation process that the hot junction valve is closed and the cold junction valve is opened to lead thermotube deformation section to relax until the thermotube deformation section contracts, thus the pressure on the piezoelectric material decreases even turns to drawing force, thereby outputting the current with reversed polarity (such as negative current).

Put powerful displacement limiting mechanism at described generating parts peripheral hardware, be used to limit the elongation of generating parts, so that piezoelectric is formed pressure;
The expansion power generation process is, closes the cold junction valve, opens the hot junction valve, and the heat pipe heat absorbing end transmits from tubular the changes section of thermal source heat absorption thermotropism, makes the expansion of heat pipe deformation section, and the piezoelectric pressurized is exported certain polarity (as just) electric current;
The contraction power generation process is, close hot junction valve, open cold end valve door, the heat pipe release end of heat transmits to low-temperature receiver from the heat absorption of heat pipe deformation section, and heat pipe deformation section is loosened until contraction, pressure on the piezoelectric reduces even becomes tensile force, thus output reversed polarity (as negative) electric current.
Basic principle of the present invention as shown in Figure 1.0 is low-temperature receiver among the figure, can be radiator, or the water cooling pond in power plant; 1 is the heat pipe release end of heat; 2 is the cold junction medium channel, should be externally adiabatic; 3 is the cold junction valve; 4 and 5 is powerful displacement limiting mechanism, is used to limit the elongation of generating parts, so that piezoelectric is formed pressure; 6 is heat pipe deformation section, makes with the material that thermal deformation coefficient is higher, should be externally adiabatic; 7 is piezoelectric, and the two sides is with electrode; 8 is the hot junction valve; 9 is the hot side medium passage, should be externally adiabatic; 10 is the heat pipe heat absorbing end; 11 is thermal source, can be coal fired boiler, waste heat source, street lamp thermal source etc.
The expansion power generation process is, closes cold junction valve 3, opens hot junction valve 8 heat pipe deformation section 6 is expanded, and heat pipe deformation section 6 and piezoelectric 7 are formed the generating parts.Because heat pipe deformation section 6 will expand, and powerful displacement limiting mechanism 4 and 5 does not allow them to expand, so the piezoelectric pressurized is exported certain polarity (as just) electric current;
The contraction power generation process is, closes hot junction valve 8, open cold end valve door 3 loosens until contraction heat pipe deformation section 6, and the pressure on the piezoelectric reduces even become tensile force, thus output reversed polarity (as negative) electric current.
Beneficial effect:
The invention has the beneficial effects as follows: make the heat generating be used for random scale, arbitrary temp condition.
The drawing explanation:
Fig. 1 is a basic principle schematic of the present invention.
Optimum implementation:
Optimum implementation of the present invention is for as shown in Figure 1.In order to improve the speed of deformation of heat pipe deformation section, need to increase the contact area of heat pipe deformation section tube wall and medium, bent limit shape is made in heat pipe deformation section cross section; In order to improve generating efficiency, piezoelectric is made sandwich (this class technology has special work introduction, as " the sandwich PZT (piezoelectric transducer) and the application thereof " of Zhang Yun's electricity work etc.), to increase compression area, but do not change pressure, the result increases output current and does not change output voltage.
The expansion power generation process is, closes cold junction valve 3, opens hot junction valve 8, and the heat pipe heat absorbing end transmits from tubular the changes section of thermal source heat absorption thermotropism, and heat pipe deformation section 6 is expanded, and heat pipe deformation section 6 and piezoelectric 7 are formed the parts that generate electricity.Because heat pipe deformation section 6 will expand, and powerful displacement limiting mechanism 4 and 5 does not allow them to expand, so the piezoelectric pressurized is exported certain polarity (as just) electric current;
The contraction power generation process is, close hot junction valve 8, open cold end valve door 3, the heat pipe release end of heat transmits to low-temperature receiver from the heat absorption of heat pipe deformation section, and heat pipe deformation section 6 is loosened until contraction, pressure on the piezoelectric reduces even becomes tensile force, thus output reversed polarity (as negative) electric current.
