Plate-fin heat exchanger

Plate-fin heat exchangers, usually composed of baffles, fins, seals, and guide fins.Place fins, guide fins and seals between adjacent two baffles to form a sandwich, called passage. The sandwich is superimposed in different ways according to the fluid, and brazed as a whole to form a plate bundle, which is the core of plate-fin heat exchanger.Plate-fin heat exchangers have been widely used in petroleum, chemical and natural gas processing industries.

Faq of Plate-fin heat exchanger

Why should the temperature condition of the cooler (or switching heat exchanger) be adjusted according to the middle temperature?

The temperature condition adjustment of the cooler (or switching heat exchanger) is based on the central temperature. The "middle" mentioned here does not refer to the central position of geometric dimension, but refers to the temperature on the barrel (or switching channel) near the central air extraction or the outlet of circulation. It is also related to the location where the thermometer is installed. The purpose of temperature condition adjustment is to keep the temperature difference between cold end and hot end within the specified range. Then, why should the temperature in the middle prevail? We need to take a look at the relationship between the temperature of the middle part and the temperature difference of the cold end and the temperature difference of the hot end, and what rules the temperature changes along the height direction of the cooler (or the switching heat exchanger) follow. The temperature condition change of the cooler (or switching heat exchanger) is general...
