Safety: The heat exchanger must be safe, and all its components must meet the requirements regarding strength, stiffness, and stability； 2. Meet the requirements of the production process: The heat exchanger must satisfy the heat transfer needs of the production process and have a certain safety margin. 3. Rational structure and high efficiency: There are many types of heat exchangers that can achieve the same heat transfer capacity, but by optimizing the structure and selecting the most appropriate design, it becomes easier to install, maintain, and clean the heat exchanger ； Choosing the most appropriate structure and flow pattern can improve the efficiency of the heat exchanger. 4. Cost savings: A rational design and proper selection of materials can help keep costs at a reasonable level
