As shown in Figure 1, the computing machine 1 of present embodiment, for example: a desktop PC, a microcomputer, a terminal device, a portable computer or a server, comprise that a central processing unit 10 is as high temperature source, it also can be other assembly that high temperature can be provided, for example an internal memory or a chip, a radiating fin 11, a radiator fan 12, a thermo-electric conversion module 13, a low temperature guide card 14 are as cold temperature source, also can be the assembly that other can provide low temperature in this cold temperature source, a for example computer housing, and another radiator fan 15 is as load.

Being located at the radiating fin 11 of central processing unit 10 tops and placing the radiator fan 12 of radiating fin 11 tops is traditional radiator structures, is no longer given unnecessary details at this.

Central processing unit 10 has a surface 100, is provided with a high temperature guide card 101 on surface 100, and this high temperature guide card 101 can be copper, aluminium or other material with high-temperature transmissibility factor and makes.

Low temperature guide card 14 is to be netted, and it can be copper, aluminium or other material with high-temperature transmissibility factor and makes.Low temperature guide card 14 is to be located between radiating fin 11 and the radiator fan 12 and since radiator fan 12 can be with air by low temperature guide card 14 places to blowing, so low temperature guide card 14 has the temperature lower with respect to high temperature guide card 101 away from the direction of low temperature guide card 14.

It constitutes a P-type semiconductor and a N-type semiconductor thermo-electric conversion module 13, and the one end connects this high temperature guide card 101, and the other end connects low temperature guide card 14.When there is temperature difference at two ends, the carrier concentration of high-temperature area can be higher than low-temperature region, can make that so carrier diffuses to low-temperature region by high-temperature area, so the uneven distribution of carrier meeting forms an electromotive force at openend, and in the loop, producing an electric current, this phenomenon also is called Seebeck effect (Seeback Effect).Whereby, thermo-electric conversion module 13 can be by the heat energy that the temperature difference produced of 14 of high temperature guide card 101 and this low temperature guide cards, and according to the principle of thermoelectric conversion its thermal power transfer is become corresponding electric energy.

Radiator fan 15 connects this thermo-electric conversion module 13 as load by two leads, can receive by the electric energy of thermo-electric conversion module 13 generations and be driven startup.

During actual start, when central processing unit 10 reaches on this high temperature guide card 101 because of running produces high heat by surface 100, thermo-electric conversion module 13 can be corresponding electric energy according to thermal power transfer that this temperature difference produced, and this electric energy provides an electric current to radiator fan 15 and then drive the actions that this radiator fan 15 rotates so that central processing unit 10 is dispelled the heat.
