Loop heat pipe heat dissipation element, loop heat pipe heat dissipation device and electronic equipment

The utility model discloses a loop heat pipe heat dissipation element, a loop heat pipe heat dissipation device and electronic equipment, and the element comprises a liquid storage cavity which is configured to contain a liquid working medium and can be communicated with a condensation channel of a condenser; the at least one liquid storage cavity is connected with the multiple evaporation cavities through gas-liquid separation walls, and each evaporation cavity can further communicate with the condensation channel; after the liquid working medium in the evaporation cavity absorbs heat from a heat source and is vaporized into gas, the gas can flow into the condensation channel to be condensed. According to the utility model, the plurality of evaporation cavities can share the working medium of the same liquid storage cavity, so that automatic proportioning and use can be realized according to different heating time and heating values of a plurality of heat sources, the heat dissipation of the plurality of hea
