The Space Anxiety of Car Refrigerators: Why Is Your Fridge Never Big Enough?
40mm of Foam Becomes 15–20mm. The Car Refrigerator, Reinvented.
Car refrigerator capacity is not just about external dimensions — it is a function of insulation physics. Polyurethane’s limited thermal conductivity (0.018–0.024 W/m·K) forces thick 40–45mm insulation walls that consume interior space. Yunqing VIP vacuum insulation panels break this trade-off: with thermal conductivity of 0.0055–0.0065 W/m·K (3× more efficient than PU), they achieve the same thermal performance at only 15–20mm thickness. The result: over 30% more usable capacity within identical external dimensions — turning insulation from a space thief into a space liberator.
