There are various elements in the design of heat exchangers, and each element plays a decisive role. Therefore, we must be familiar with and understand the design elements of heat exchangers to help us better choose heat exchangers.
1. According to the maximum operating temperature and pressure of the heat exchanger, its thermal design concept and frictional resistance value, determine the raw materials and specifications of each component to ensure the smooth operation of the heat exchanger.
2. According to the working temperature, pressure and fluid characteristics of the heat exchanger, select the welding process and rubber seal.
3. With the overall goal of ensuring the symmetry of fluid distribution, the design concept of stainless steel head, header, butt joint and baffle was carried out.
4. In order to consider the overall design of the heat exchanger's heating and frictional resistance characteristics, the strength of key components should be checked to prevent damage or excessive selection of materials due to insufficient compressive strength under extreme working conditions, resulting in waste.
5. Maintenance includes cleaning, repair and maintenance, etc. and transportation regulations for heat exchangers.
6. For some heat exchangers that work under unique standards, some of them must measure welding stress during start-up and shutdown, promote structural changes caused by fluid mobility, or calculate water flow to reduce the corrosion and structure of the heat exchanger. dirt.
In short, the overall design and the thermal design concept have the same necessity, and the design and concept of the heat exchanger must be combined separately and coordinated with each other. The above content is an introduction to the design elements of our heat exchanger. We should also consider the factors of plate heat exchanger manufacturers and heat exchanger model factors.
