① According to the maximum working temperature and pressure of the heat exchanger, as well as the results of thermal design and resistance calculation, determine the materials and dimensions of each part to ensure the performance of the heat exchanger during stable operation.
② According to the working temperature, pressure and fluid properties of the heat exchanger, select the welding method and sealing material.
③ With the goal of ensuring the uniformity of fluid distribution, the design of heads, headers, piping and partitions is performed.
④ In order to meet the structural design of the heat exchanger and resistance performance of the heat exchanger, the strength check of the main components must be performed to avoid waste due to insufficient strength and material damage caused by insufficient strength under extreme working conditions.
⑤ The requirements for heat exchanger maintenance (including cleaning, repair and maintenance) and transportation should be considered.
⑥ For some heat exchangers working under special conditions, some must also calculate their thermal stress during the start and stop periods, account for structural changes caused by fluid flow, or check calculations to reduce heat exchanger corrosion and scaling. Flow rate. In short, structural design and thermal design have the same importance. When designing the heat exchanger, it is necessary to consider both, and they should be coordinated with each other.
