特点：Recovery Heat Exchanger Features:
High thermal conductivity, especially evident in air-water waste heat recovery heat exchangers.
2. Large average temperature difference in heat transfer. The channels for cold and hot fluids are conveniently arranged, and the flow direction can be set up in a simple counter-current pattern.
3. Compact structure. With fins added to the outside to increase the surface area for heat dissipation, each heat exchange tube has a higher heat transfer capacity, allowing for the transfer of heat with fewer tubes.
4. Flexible arrangement. Heat exchanger tubes can be used as universal heat transfer elements and can be arbitrarily combined by changing the number of tubes.
