Plate heat exchangers were first put into commercial production in the 1930s and are now being used more and more widely in water supply, heating, and air conditioning projects in industrial and civil buildings. The correct selection of plate heat exchangers can ensure the smooth implementation and use of the project. Here we introduce how to select the heat exchanger.

The heat exchanger is a process equipment that transfers the heat between different temperature media by heat conduction from high-temperature objects to low-temperature objects when the objects reach the required temperature for production. At present, heat exchangers are not only used in large chemical raw material manufacturers but also have entered the daily use of thousands of households. Below we introduce two common heat exchanger failures.

The plate heat exchanger is a new type of high-efficiency heat exchanger made of metal plates stacked with certain corrugated shapes. The structure includes gaskets, compression plates, and frames, the plates are sealed and guided by sealing gaskets, separating the cold and hot two fluid channels. Different media flow through the respective channels and exchange heat with the separated plates to achieve the required temperature. Next, we will introduce the advantages of the plate heat exchanger.

The heat exchanger is widely used in the circulating water system for winter heating in family buildings, office buildings, hotels, etc. After use for a period of time and after the end of the pipeline construction without slag flushing, resulting in a large amount of internal scale and welding slag foreign matter, clogging the pipeline, resulting in poor heat exchange effect. Therefore, it must be cleaned regularly to restore its original efficiency.

With the widespread use of heat exchangers, ordinary people are coming into contact with more and more heat exchangers. It is also important to acquire some knowledge about heat exchangers and to learn how to install them. Here we take the displacement heat exchanger as an example and explain its pe
