1.When purchasing finned heat exchangers, try to purchase ones with high heat transfer coefficients. When the same heat exchange is required, try to choose one with a large windward area instead of one with multiple rows. To fully utilize the advantages of enhanced fins without increasing the power of the fan.

2. When selecting materials, one should consider their own operating conditions and economic capabilities. If the medium used is corrosive, stainless steel material should be selected; If only economic factors are considered, copper or aluminum materials can be selected.

3. In terms of installation, use, and process, it is required that the finned radiator should have a certain mechanical strength and pressure bearing capacity. The structural form should be easy to assemble into the required heat dissipation area.

4. The requirements for hygiene and aesthetics are smooth appearance, no dust accumulation, and easy cleaning.

5. When installing the heat exchanger, consideration should be given to maintenance, and the opening area should be such that the entire set of heat exchangers can be disassembled and lifted out. When there is a problem with the heat exchanger, it can be easily lifted out to expose the entire pipeline, fins, and riser. There should be space for disassembly and valve replacement at the opening of the branch valve.
