What external factors affect the cold retention duration of phase change ice boxes during transportation?
2026-06-13
Apart from the quality and quantity of ice boxes, external environments greatly impact the actual cold retention effect.
Ambient temperature: High summer temperatures, direct sunlight and stuffy enclosed vehicle compartments accelerate cold loss.
Material and thickness of incubators: Thicker and better-sealed incubators slow down cold leakage and greatly extend cold retention time.
Transit times: Frequent opening of boxes for loading and unloading during transit leads to cold air escape and shorter constant temperature duration.
Ventilation and sunlight: Exposure to direct sunlight and strong wind speeds up heat exchange.
To maximize the cold retention performance of phase change ice boxes, use thickened incubators, reduce box opening times and avoid direct sunlight during transportation.
