US 12,098,022 B2 · Devices and methods for blast containment

Abstract

Devices and methods for blast/fire containment are disclosed herein. Devices include containers designed to contain and/or mitigate high energy events such as blasts from explosions or thermal runaways. The containers include a body that is built to define an interior chamber shaped to receive an explosive device or a device susceptible to thermal runaway. The container comprises a plurality of substructures that are arranged in a layered sequence to provide the desired effect. The substructures act in concert to decouple the shock load to the main containment structure using shock decoupling with energy dissipation and attenuation technology, having a highly deformable polymer structure, and managed venting. In thermally dominated events, such as a runaway LI battery fire, a crushable medium present in one or more layers of the container presents a significant thermal barrier and contains the fire.

Dependent claims

A container for containing and mitigating high energy events, said container comprising:

a body shaped to define an interior chamber and an opening through which said interior chamber can be accessed when said container is in an unassembled state, said body comprising a plurality of layers arranged in an ordered sequence, said plurality of layers comprising:
a first layer adjacent to said interior chamber, wherein said first layer comprises a metallic foam;
a second layer disposed adjacent to said first layer and opposite said interior chamber comprising a pressed inert powder;
a third layer disposed adjacent to said second layer and opposite said first layer;
and
a fourth layer disposed adjacent to said third layer and opposite said second layer;
a lid shaped to cover said opening such that when said lid and said body are assembled such that said container is in an assembled state, said interior chamber is fully enclosed within said container;
and
a fastener for affixing said lid to said body.
