(2), the present invention different with traditional cooling system be, the heat energy of main frame and the cold energy that exists naturally are not excluded, but are translated into electric energy, therefore produced additional electric energy, and needed to use its useful effect sharp increase for main frame or it.

(3), the present invention uses on motor, need not to be provided with separately water tank, fan, radiator etc. are installed, and therefore, can reduce the fixed investment cost of motor effectively.

(4), simplicity of design of the present invention, rational in infrastructure, easy to maintenance, remove beyond the patent art, related correlation technique comparative maturity is implemented easier.

(5), the present invention can use on internal-combustion engine, external-combustion engine, turbogenerator and wind-power electricity generation and permanent magnet generator, that is to say that using scope of the present invention is very extensive, promotional value is high.
