Heat exchanger can transfer heat from high temperature fluid to low temperature fluid, so that the fluid temperature can meet the requirements of process conditions, and it is also one of the main equipment to improve energy utilization.
Heat exchangers can be classified in different ways. According to its operation process, it can be divided into three categories: partition type, mixed type and regenerative type (or regenerative type); According to the compactness of its surface, it can be divided into dense and non-dense types.

Matters needing attention in the use of heat exchanger:
1, keep the pipe network clean. Whether before or after work, the pipe network must be cleaned to avoid the phenomenon of heat exchanger blockage. Attention should also be paid to the timely cleaning of the decontamination device and filter, so that the whole work can be completed smoothly.
2. Strictly control softened water. It is very important to check the water quality. On the premise of dealing with the softened water quality, we should first carefully check the water quality problems of the system and softening tank, and then inject water after it is qualified.
3, the new system inspection. For some new systems, they cannot be used interchangeably with heat exchangers immediately. First, the new system needs to run for a specified period of time, and then the heat exchanger can be incorporated into the system. The purpose of this is to avoid impurities in the pipe network from damaging the heat exchanger equipment.
