It is impossible to increase indefinitely. Because the expansion of heat transfer area and temperature difference are often limited by site, capital and equipment effect. Therefore, the main direction of the technical evaluation of plate heat exchanger is how to improve the heat transfer enhancement effect of plate heat exchanger by controlling the heat transfer coefficient value of plate heat exchanger. Nowadays, many technologies are used to improve the heat transfer coefficient of plate heat exchangers. By adding spoiler additives in the heat exchanger tube of plate heat exchanger, the heat transfer resistance of plate heat exchanger in heat transfer process is greatly reduced, and the heat transfer coefficient of plate heat exchanger is improved.
The total thermal resistance of plate heat exchanger is the superposition of all kinds of heat transfer resistance in the process of using, so to change the heat transfer coefficient, it is necessary to analyze how each kind of heat transfer resistance controls each kind of heat transfer resistance of plate heat exchanger, which is the key to determine the heat transfer coefficient of plate heat exchanger.
