Finned tube heat exchangers is a kind of heat exchange equipment most widely used in gas and liquid. To achieve the purpose of strengthening heat transfer, the fins with horizontal and vertical are added in the surface of base tube. Although there are many forms of physical structure, the basic structure is made up of parallel plate and assembled plate bundle consist of various forms of fins. | ||||

Plate heat exchangers have been widely used in central heating, food, machinery, metallurgy, the petrochemical industry, and ships, and have become the leading heat exchange equipment in urban central heating projects. In order to ensure the normal operation of the plate heat exchanger and prolong the service life of key components, it is especially important to understand the failures of the plate heat exchanger, their causes, and treatment methods. The following is a description of how to deal with the heat exchanger when the pressure drop is too large.
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.
With increasing use, the heat exchanger's heat transfer efficiency will inevitably be affected, thus affecting normal operation. There are many reasons for the low heat transfer efficiency of plate heat exchangers. Because we all know that the plate heat exchanger heat transfer efficiency is very high, and this is one of the reasons why people often choose it. Today we will discuss this issue.
Even a plate heat exchanger can have problems during the course of a year and require maintenance, especially its seals, to see if it has loosened.
The plate heat exchanger is a new type of high-efficiency heat exchanger made of metal sheets with certain corrugated shapes stacked on top of each other. A thin rectangular channel is formed between the various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal equipment for liquid-to-liquid and liquid-to-vapor heat exchange.
Heat exchangers are devices used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements and are an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. Its operation process can be divided into three main categories: inter-wall, hybrid, and heat storage. According to its surface compactness can be divided into two categories: compact and non-compact. Next, let's learn about the history of heat exchanger development.
