Direct conduction-Peltier effect refrigeration mixed cooling method and device

The invention relates to a direct pass-Peltier effect refrigeration composite radiation device, which is used for solving the problem of radiation of electronic devices with large heating power; the device comprises a heat collecting plate for clinging to the upper surface of the electronic device; the upper surface of the heat collecting plate is provided with a Peltier effect refrigerant plate;the area of the Peltier effect refrigerant plate is less than the area of the upper surface of the heat collecting plate; the surface of a low-temperature terminal clings to the upper surface of the heat collecting plate; the surface of a high-temperature terminal of the Peltier effect refrigerant plate clings to a first heat conducting plate clings to; the upper surface of the first heat conducting plate is provided with a first radiator and a first radiating fan; the rest of the upper surface of the heat collecting plate except the part covered by the Peltier effect refrigerant plate clingsto a second heat conductin
