The invention, which relates to the technical field of the distribution box, discloses a distribution box with dual-sealing protection and self-adaptive heat dissipation functions, comprising a distribution box body, and a closing mechanism for closing the distribution box body at a low temperature is arranged outside the distribution box body. A locking mechanism for enhancing the sealing performance of the distribution box body is further arranged outside the distribution box body, a turnover mechanism is further arranged inside the closing mechanism, and a blowing mechanism for preventing sundries from blocking is further arranged outside the distribution box body. Paraffin oil expands when heated to push the piston to move downwards, the cover plate is driven to be opened, hot air exhaust is promoted, when the temperature is lowered, the paraffin oil shrinks, the cover plate automatically closes and seals the exhaust port, rainwater and moisture are effectively prevented from entering the box body, efficient heat dissipation under the high-temperature working condition is guaranteed, the water inflow risk in the low-temperature humid environment is avoided, and the service life of the box body is prolonged. And the operation safety and the environment adaptability of the distribution box are improved.
