Description

Technical Field

[0001] This invention relates to the automotive field, and in particular to an energy recovery air duct device for a vaccine refrigerated transport vehicle. Background Technology

[0002] Poor airflow circulation can occur in refrigerated truck compartments after cargo is loaded, leading to temperature differences on some cargo surfaces and resulting in ineffective temperature control within the compartment. Patent (CN201520448807.1) describes a refrigerated truck compartment structure that primarily relies on a deflector and three different sizes of air ducts for airflow guidance. This device requires high precision in sheet metal processing and incurs high costs for installation, disassembly, and maintenance. Furthermore, it necessitates the installation of multiple temperature sensors and wiring inside the compartment, which reduces the overall insulation and sealing performance. The lack of corresponding vibration damping measures during cargo transport also results in insufficient stability and increases the risk of cargo damage. Summary of the Invention
