Cooling System for Protective Helmets Using Phase-Change Materials and Gas Expansion

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a device for reducing thermal stress and regulating the microclimate inside a protective helmet. This is achieved by integrating at least one capsule arrangement containing phase change material (PCM) into the helmet shell and/or providing a compressed gas line to allow cooling by expanding gas inside the helmet. The patent also covers a protective helmet equipped with this device.

Patent Abstract

The invention relates to a device for reducing thermal loads and regulating the microclimate in a protective helmet (H), wherein at least one capsule arrangement (3, 4) with phase change material (PCM) is integrated into a helmet shell (1) of the protective helmet (H) and/or that a pressurized gas line (5) leads to the helmet shell (1), by means of which expansion cooling using a cooling gas inside the protective helmet (H) can be realized. Furthermore, the invention relates to a protective helmet equipped with the device.
