Portable Vaccine Cold Boxes: Structure and Working Principles
2025-08-11
Portable vaccine cold-chain insulation boxes(medical cooler boxes) are crucial for safe vaccine transportation. Their structure features multi-layer protection: an outer shell made of PP / ABS or metal material resists impact and temperature transfer. Inside, a PE / metal inner container ensures hygiene.
Equipped with digital temperature monitors, they track real-time conditions. The working principle relies on thermal resistance: insulation materials block external heat, while phase-change materials release cold energy when temperatures rise, keeping the internal environment at -25~-155~25
