AI Technical Summary
In existing volumetric heat exchangers, the medium flow in the heat exchange chamber and heat exchange tubes is insufficient, resulting in uneven contact between the medium and the heat exchange tubes, which affects the heat exchange effect. Furthermore, scale easily forms on the outer wall of the heat exchange tubes, reducing the heat exchange efficiency.
A turbulence-inducing mechanism (rotating ring and turbulence-inducing vanes) is installed inside the heat exchange cylinder to promote uniform medium flow, and a cleaning mechanism (sliding disc and annular scraper) automatically removes scale, while a funnel-shaped bottom design allows for the periodic discharge of impurities.
It improves the overall heat exchange efficiency of the heat exchanger, ensures the cleanliness of the outer wall of the heat exchange tube, avoids scale buildup, and reduces maintenance costs.
