The particular shell and tube heat exchanger consists of the shell, the particular heat transfer tube pack, the tube sheet, the baffle plate (baffle plate) as well as tube box. The shell is mostly cylindrical, and a television bundle is installed on the inside, and the two ends belonging to the tube bundle are fixed on the tube plate.
There are two forms of hot and cold bodily fluids for heat exchange, some may be flowing inside the tube, called the tube-side liquid; the other is coursing outside the tube, labeled the shell-side fluid.
So as to improve the heat transfer coefficient on the fluid outside the tv, several baffles are usually installed within the shell. The baffle can boost the velocity of the shell-side water, forcing the fluid to move across the tube bundle laterally multiple times reported by the prescribed distance, and enhancing the degree of fluid turbulence.
There might be many variations on that shell and tube style. Typically, the ends of each one tube are connected to help plenums (sometimes called normal water boxes) through holes with tubesheets. The tubes might be straight or bent while in the shape of a OUGHOUT, called U-tubes.
In nuclear electrical power plants called pressurized drinking water reactors, large heat exchangers known as steam generators are two-phase, shell-and-tube warmth exchangers which typically have got U-tubes. They are employed to boil water recycled from your surface condenser into vapor to drive a turbine to create power. Most shell-and-tube heat exchangers are either ONE PARTICULAR, 2, or 4 pass designs within the tube side. This refers to the amount of times the fluid while in the tubes passes through the fluid in the shell. In a sole pass heat exchanger, the fluid goes in one end of each tube and out the opposite.
Surface condensers in power plants in many cases are 1-pass straight-tube heat exchangers (see Surface condenser for diagram). Two and four complete designs are common as the fluid can enter and exit around the same side. This makes construction more simple.

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.
