AI Technical Summary
Existing durable tubular heat exchangers are prone to damage to the inner tubes when hot fluids expand, making them unable to move freely and resulting in thermal stress damage.
The design employs a heat exchange component and a baffle component. The heat exchange component uses a magnet to attract and move the inner tube slightly, while the baffle component uses an elastic component to buffer the impact of the hot fluid and reduce damage to the inner tube.
It effectively reduces damage to the inner tube body during thermal expansion, enhances durability, prevents hot fluid from directly impacting the inner wall, and reduces equipment wear.
