Patent ID: 10095285

Abstract:
A portable electronic device using a fixed main heat-dissipating module and a detachable auxiliary heat-dissipating module for contacting the fixed main heat-dissipating module. The detachable auxiliary heat-dissipating module includes an outer casing structure and an inside mounted heat-dissipating structure. The outer casing structure includes a detachable casing detachably disposed inside a predetermined receiving groove of the portable electronic device and an electrical connector electrically connected to the portable electronic device. The inside mounted heat-dissipating structure is disposed inside the detachable casing. The inside mounted heat-dissipating structure includes an inside mounted heat-dissipating fan, a plurality of inside mounted heat-dissipating fins, a pump, and a circulation pipe. The circulation pipe has a contact portion exposed from the detachable casing to directly contact the fixed main heat-dissipating module, such that heat generated by the fixed main heat-dissipating module is partially transmitted to the circulation pipe through the contact portion.
