How Can a Car Refrigerator Hold More and Stay Cold Longer After a Power Outage?
Insulation Material Selection Is Key
This article compares three mainstream insulation materials for car refrigerators: EPP foam, traditional fiberglass VIP and SuperCooler Yunqing VIP. Yunqing VIP strikes a good balance of lightweight and thermal‑insulation performance. With thermal conductivity of 0.0055‑0.0065 W/(m·K), it achieves equivalent insulation at only 15‑20 mm thickness, expanding usable internal capacity by over 30%. It improves portability, extends cold‑hold duration after power loss and lowers energy consumption, ideal for portable camping and self‑driving car refrigerators. Material‑selection guidance for different‑grade car‑refrigerator products is also provided.
