The application discloses a high-flux heat exchange device based on a thermo-chemical reaction auxiliary, which comprises a heat exchange chamber and a chemical phase change working medium. The chemical phase change working medium comprises a liquid cooling base fluid and a reversible thermal decomposition solute. The thermal decomposition temperature threshold of the reversible thermal decomposition solute is lower than the physical boiling point of the liquid cooling base fluid under the current environment.
