中文(简体)High temperature heat pipe heat exchangers also face two urgent issues in heat transfer:
The large-scale planning and high cost of high-temperature heat pipe heat exchangers greatly hinder their industrial application process.
2. The connection of the transition section is unreasonable, resulting in some heat pipes being in non working and abnormal working conditions.
The key to addressing the above issues is:
There are two methods for optimizing the design of high-temperature heat pipe heat exchangers: one is to study the enhanced heat transfer of a single heat pipe; The second is to reasonably guess the distribution of the shell side flow field and temperature field. The combination of the two is the future development direction of enhanced heat transfer technology for heat pipe heat exchangers.
2. The enhanced heat transfer in the transition section plays a crucial role in optimizing the planning of high-temperature heat pipe heat exchangers and safely connecting heat pipe heat exchangers in various regions.
Research status of domestic heat exchangers
According to their functions, they can be named condenser, evaporator, reheater, and superheater. According to the characteristics of heat exchange components, they can be divided into shell and tube heat exchangers, finned tube heat exchangers, and plate heat exchangers (including plate heat exchangers and plate fin heat exchangers). The research on various heat exchanger enhancement techniques mainly focuses on the changes in fluid flow patterns inside the heat exchanger and the optimization of various component parameters. The main research strategies for the parameters of heat exchanger components include the arrangement of heat exchange tubes (plates) (in sequence or horizontally), the number of rows of heat exchange tubes (plates), the spacing between heat exchange tubes (plates), and the spacing between fin and rib shapes. Common research methods include numerical simulation calculation, experimental method research, and theoretical research.
