This invention belongs to the field of energy-saving heat exchange technology, specifically a heat exchanger with a protective structure, including a heat exchange box. Heat exchange tubes are fixedly connected to the combustion chamber inside the heat exchange box. A purified water pump pumps circulating cleaning fluid to backwash the inner wall of the heat exchange tubes to remove scale, thus protecting the inner wall of the heat exchange tubes from scale buildup and ensuring efficient heat transfer and reduced energy consumption. By using the heat exchange tubes inside the heat exchanger as a circulation channel for the cleaning agent in a counter-current flush, the reverse flow of the cleaning agent impacts the weak points of scale buildup on the tube wall. Scale, which usually deposits in the direction of flow, is more easily peeled off in the reverse flow, effectively removing stubborn scale. Utilizing the heat exchange tubes as the circulation channel for scale removal, the cleaning agent is directly pumped into the existing piping system, eliminating the need for disassembling the heat exchanger end caps and tube bundles as in traditional models, achieving a non-disassembly cleaning function. This heat exchanger is suitable for home and commercial use, and is particularly applicable to continuous production in the chemical and power industries.
