Development prospects of heat exchangers
Due to the late start of research on heat exchangers in China compared to foreign countries, the technology is relatively backward, and the theoretical research on heat exchangers is insufficient
Mature, lacking systematic research. There are some external influencing factors, such as the environmental factors in which the research was conducted and the ones used during the research
The material factors, differences in the accuracy of measuring instruments during research, and other factors can lead to deviations in research results. The significance of guidance is unclear
Big. The research on heat exchangers in China has not yet reached three-dimensional heat transfer, as the research is only a prerequisite for one-dimensional and two-dimensional research
Relatively demanding, the conclusions drawn do not have broad guiding significance.
2.1 Overall Design Database
Future research on heat exchangers should focus on fundamental theoretical innovation, and the results of the research can be widely applied. Replace the heat exchanger
Corrosion resistance, material hardness, and heat transfer ability should all be improved. To have an overall designed database, it is not necessary to
Using traditional manual calculation and design methods, instead of staff inputting information into the database, there will be different applications in the database
Analyze and calculate data using software. You can directly obtain the task data required for the design. This not only saves time but also saves time
Save manpower. This will be a new way of calculating heat exchangers in the future.
2.2 Broadness of research directions
In the future, the shape of heat exchangers will not only be rectangular or circular, but will be adjusted according to the engineering situation of the required heat exchanger
Improvement. Heat exchange efficiency is no longer the standard for measuring heat exchangers. The most efficient and cost-effective heat exchanger is the best choice
Choose. Therefore, factors that affect friction and heat transfer have become the most suitable criteria for measuring the selection of heat exchangers. These two factors are missing one
No, if only one of the factors meets the standard, it will not have any impact on the selection of the heat exchanger.
2.3 Computer simulation of fluids
Using computer models to design heat exchangers is also one of the future technologies to be developed, which involves simulating the fluid flow in the heat exchanger through computers
Analyze the flow process and flow patterns. At present, simulation flows such as vibration flow mode and convection mode have been achieved for heat exchangers
Move. Analyze the results of computer simulation flow to gain a better understanding of heat exchangers and improve their performance
Can.
3 Conclusion:
In summary, heat exchangers are one of the widely used equipment in industry, and China's demand for heat exchangers ranks among the highest in the world
At the forefront, it is necessary to strengthen research related to heat exchangers. Currently, research on heat exchangers has reached a deeper level
However, there is still a gap between China and developed countries, so it is important to draw on relevant experience and strengthen research on the performance of heat exchangers
It is particularly important. On the basis of improving the theoretical knowledge of heat exchangers, it is also necessary to strengthen the practical application, which requires researchers to make
A large number of experiments have been conducted to obtain the optimal solution, and there is still room for development in this area in China. Do these things well, the heat exchanger's development
The exhibition prospects will be very promising.
