Cooling System for Protective Helmets Using Phase-Change Material or Gas Expansion

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

The invention is a device designed to reduce thermal stress and regulate the microclimate inside a protective helmet. It does this by integrating at least one capsule containing phase change material (PCM) into the helmet shell, or by supplying a cooling gas through a pressure line to enable expansion cooling within the helmet.

Use CasesContent extracted from patent full text and abstract with AI.

• Protective helmets for firefighters working in high-temperature environments
• Industrial safety helmets used in hot workplaces or foundries
• Sports helmets for athletes in extreme heat conditions
• Military helmets to prevent heat stress in soldiers
• Construction helmets for workers outdoors or in hot climates

BenefitsContent extracted from patent full text and abstract with AI.

• Improves user comfort by maintaining a cooler temperature inside the helmet
• Reduces risk of heat-related injuries or thermal stress for the helmet wearer
• Enables longer and safer use of protective helmets in hot environments
• Flexible technology—can be applied through PCM capsules or active cooling gas systems
• Potentially increases productivity and safety for workers or users needing head protection in heat

Patent Abstract

Device for reducing thermal loads and regulating the microclimate in a protective helmet (H), characterized in that 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), with which expansion cooling by means of a cooling gas inside the protective helmet (H) can be realized.
