AI Technical Summary
In existing heat recovery devices, the contact area between the heat exchange components and the low-temperature waste heat fluid is limited, resulting in heat waste of the waste heat fluid and reduced waste heat recovery efficiency.
The design employs a serpentine heat exchange tube and surface-mounted heat transfer fins, combined with a gas-liquid two-phase flow heat exchange method, to increase the contact area and accelerate heat transfer.
It improves the effectiveness and efficiency of waste heat deep recovery, enabling faster heat absorption and utilization.
