Heat exchangers: classification and uses

A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, that is, water or other medium is placed in a large closed container, and a pipe is passed through the container. Let hot water flow through the pipe.

Due to the temperature difference between the hot water in the pipe and the hot and cold water in the container, heat exchange is formed, which is the thermal balance of the junior high school. The heat of the high-temperature object is always transferred to the low-temperature object, thus the heat of the water in the pipe is exchanged to the container. The cold water inside, the heat exchanger is also called the heat exchanger.

Heat exchangers can be classified according to their use: coolers, condensers, heaters, heat exchangers, reboilers, steam generators, waste heat (or waste heat) boilers.

According to the heat exchange method can be divided into direct contact heat exchangers (also known as hybrid heat exchangers), regenerative heat exchangers and partition wall heat exchangers.
