| 摘要 |
A power circuitry with a thermionic cooling system is provided. The system includes a voltage regulator and a heat rectifying device to cool the voltage regulator. The heat rectifying device includes a heat collector and a heat barrier, formed between the voltage regulator and the heat collector. An auxiliary voltage generator enables the electrons of the voltage regulator to tunnel onto the heat collector through the heat barrier. The voltage regulator may include a shared substrate and power transistors, generating a regulated voltage. In some embodiments the controller keeps a temperature in a preselected range by controlling the power transistors, the auxiliary voltage generator, and a fan. In some embodiments a load is integrated together with the thermionic cooling system so that the load itself can be cooled by the heat rectifying device.
