Not much is known about heat exchangers; they are usually discussed only in the circles of mechanical engineers and chemical engineers. However, they are found all over the world in conventional appliances, such as air conditioners and refrigerators, and the other is a radiator in cars.
The basic principle underlying heat exchangers is the transfer of heat from one medium to another. For example, a car radiator allows you to cool a hot fluid from an engine when the fins of a radiator radiate heat into the air that flows over its surface. Some factors affecting the efficiency of heat exchangers are the flow rate of the fluid and the total surface area of the wall that separates the fluids. To increase the surface area of the contact walls, fins and grooves are added, this is an effective measure.
Of the 4 types of heat exchanger, the shell and the tubular configuration are the most common, as well as reliably easy to maintain. This system has several tubes with fluid passing inside them and simultaneously passing through them. This allows heat transfer.
The other is the regenerative type, which is common in gas cooling applications, which affects heat generation in one process and transfer to another, also known as heat recovery. Lamellar and intermediate heat exchangers are other types.
The configuration of the plate uses the same technique as the shell and tube exactly here, when the liquid enters through the layers of cavities between several plates, the result is a large surface area. This configuration is considered the best thermodynamic characteristic for this application and is widespread in the engineering world. But it is more laborious and time consuming than a heat exchanger with a shell.
The way in which fluid flows through this equipment is divided into 3 main groups. These flow devices are transverse, countercurrent and parallel streams. Of these, the counter flow configuration transmits the greatest amount of heat.
