This invention discloses an integrated fire-fighting device and method for thermal runaway, comprising an integrated fire-fighting body and a fire-fighting unit. The integrated fire-fighting body has a through hole and an aerosol generating chamber inside. The aerosol generating chamber contains a thermally sensitive wire, a fixed bracket, a connecting joint, a temperature-sensing element, a sealing cover, and aerosol. In this invention, the sealing cover is pressed tightly against the connecting joint by the temperature-sensing element, which can seal the fire-fighting medium in the fire-fighting medium channel. When the temperature-sensing wire reaches a set threshold, physical deformation occurs, triggering the release of aerosol, causing the aerosol to initially immerse the space where the integrated fire-fighting body is located. Then, the temperature-sensing element is driven to melt or rupture, connecting the fire-fighting medium channel with the aerosol generating chamber to release the fire-fighting medium for cooling. After the gas cooling agent is released, the pressure trigger valve detects the preset pressure and opens the spray nozzle to immerse the space again, achieving effective fire extinguishing, cooling, and decontamination even when not affected by strong magnetic fields.

This invention belongs to the field of electrical distribution box technology, and particularly relates to a theft-proof and secure intelligent electrical distribution box, comprising a distribution box, an anti-theft component, a heat dissipation component, a water-cooling component, and a fire extinguishing component.
