AI Technical Summary
Existing heat exchangers have short return passes, resulting in low heat utilization of water or steam. Furthermore, water or steam at different temperatures moves along the same path, which can easily lead to the problem of low-temperature water or steam continuing to absorb heat.
The design of a multi-pass rapid-heating electric boiler heat exchanger employs diversion plates arranged at equal intervals and staggered inside the heat exchanger shell to form a bent loop. The structure is reinforced by multiple openings and a fixed base to increase the flow path of water or steam, enabling heat conduction and discharge from a designated outlet.
It improves heat exchange efficiency, prevents low-temperature water or steam from continuing to flow and absorb heat in the heat exchanger, and enhances heat utilization.
