Specific embodiment
Following examples will be further limited with reference to accompanying drawing to the present invention.
Referring to Fig. 1~3, the embodiment of the present invention is provided with high temperature heat reservoir 1, low temperature heat reservoir 2, lever system long 3 and fixing axle 4；Institute
The left end for stating lever system long 3 is connected with high temperature heat reservoir 1 and heats lever system long 3, right-hand member and the low temperature heat reservoir 2 of lever system long 3
It is connected and make lever system long 3 to cool down, the center of lever system long 3 is fixed in fixing axle 4, lever system long 3 overturns and makes leverage long
The two-end-point of system 3 is not stalled between high temperature heat reservoir 1 and low temperature heat reservoir 2 and changed.
In fig. 2, mark 5 is that high temperature heat reservoir temperature change 1,6 is high temperature heat reservoir temperature change 2；In figure 3, mark 7 is
Low temperature heat reservoir temperature change 1,8 is low temperature heat reservoir temperature change 2.
Using this momentary operation enhancing heat transmission is overturn, comprise the following steps that：
1) left end point of lever system long 3 is contacted with high temperature heat reservoir 1；
2) right endpoint of lever system long 3 is contacted with low temperature heat reservoir 2；
3) central point of fixation lever system 3 long；
4) overturn lever system 3 long, the left end for making the temperature of lever system long 3 relatively low is connected with high temperature heat reservoir, due to the temperature difference compared with
Greatly, the left end of lever system long 3 is heated rapidly；Meanwhile, the temperature of lever system long 3 right-hand member higher is connected with low temperature heat reservoir, equally,
Because the temperature difference is larger, the right-hand member of lever system long 3 is cooled down rapidly；
5) overturn lever system 3 long, the right-hand member for making the temperature of lever system long 3 higher is connected with low temperature heat reservoir, due to the temperature difference compared with
Greatly, the right-hand member of lever system long 3 is cooled down rapidly；Meanwhile, the relatively low left end of the temperature of lever system long 3 is connected with high temperature heat reservoir, equally, by
Larger in the temperature difference, the left end of lever system long 3 is heated rapidly；
6) repeat step 4)~5), and until lever system long 3 reaches quasi-steady state, the calculating treatment of correlation being carried out, acquisition is turned over
Turn the virtual value of the hot attribute of sample.
Figure 4 and 5 are respectively under different sample conditions, the Temperature Distribution of lever system long obtained by the present invention.Fig. 4 is certain sample
Reach temperature profile during quasi-steady state；Fig. 5 is Temperature Distribution result of calculation of certain sample under instantaneous state.
Under Fig. 6 is different sample conditions (long lever system intrinsic heat conductance different), the efficient thermal conductivity obtained by the present invention
With the ratio and the graph of a relation of toggle frequency of intrinsic thermal conductivity.

Fig. 8~10 be one of which of the invention may working method be to make it among the fluid for being placed on upper heat and lower cold
Reach the effect of energy transmission.Because the bottom temp of water is lower than upper surface, it is difficult to produce convection current, therefore put at container lower-left end
A thermal source is put, it is driven the motion of neighboring area water, so as to drive the rotation of stock to reach the effect that energy is transmitted.
It has been primarily upon two aspects：A () is placed in heat energy and the flow rate of liquid in container that the static thermal source in the container lower left corner is discharged
Relation；B () is from the heat transfer energy in the incoming water in stock tip.Fig. 8 is measured water after thermal source R is placed at container lower-left end

The waterpower device of axle is placed in the design sketch rotated among the fluid of cold (3 DEG C) under hot (23 DEG C).Because thermal source is placed on
Turning hinders the motion of fluid, therefore, the flow velocity non-zero of container center.The convection current that fluid circulation increased generation can overcome
The possibility of viscosity resistance.Additionally, this small flow velocity can be exaggerated by the conversion of gear, to drive small generator.
This is that 0.001 upset system effect per second is of equal value with frequency.Be can obtain from Fig. 6, efficient thermal conductivity can increase to
Many times of intrinsic thermal conductivity.If the density identical material of the material selection of stock and water, stock can as water in itself
Motion, the sub-fraction heat of bottom is enough to drive it to rotate.
