AI Technical Summary
Existing low-temperature testing technologies are inefficient and lack temperature uniformity, failing to meet the needs of enterprise-level SSD batch verification. Furthermore, traditional fixing methods are time-consuming and not airtight, affecting the accuracy of test results.
The design employs a hanging bag system, combined with zipper and chain structures, to suspend solid-state drives for low-temperature testing inside the freezer via ropes. The double-layer stainless steel shell and internal cooling system enable rapid loading and high-density synchronous testing, ensuring temperature uniformity and independent testing units.
It achieves efficient and rapid multi-sample low-temperature testing with a temperature uniformity of ±1.5℃, significantly improving loading efficiency and testing accuracy, and supporting enterprise-level SSD batch verification.
