3 Types of Heat Exchangers
Posted in Uncategorised, on January 13, 2022 By Admin
A heat exchanger is a device that transfers energy from one medium to another by means of molecular conduction or radiation. They are typically used to transfer thermal energy from a hot fluid to a cooler one, thus reducing the temperature difference between them. As a result, heat exchangers are valuable for specific equipment because they help keep the machine running efficiently and extend its lifespan. These valuable pieces of equipment also come in 3 variations.
Here are the 3 types of heat exchangers used in various machines and equipment.
Kettle Type
A kettle heat exchanger is a device that transfers heat between a fluid and a vapour, typically used in power plants to condense steam back into a liquid. As the fluid circulates through the tubes, it removes heat from the hot vapour on one side of the exchanger. On the other side, the heating process is reversed as the now-hot fluid circulates over to transfer its heat to cold vapour on the other side.
Plate Type
A plate heat exchanger is a device that is used for transferring heat from one fluid to another by means of a metal plate. A difference in temperature causes a pressure difference between the two fluids, which leads to a difference in density and thus creating a current of hot fluid on one side of the plate and cold fluid on the other. Plate heat exchangers are used in many industrial settings because they are efficient, competitively priced, and easy to maintain.
Special Tubular Type
Special tubular heat exchangers are pieces of equipment that allow for heat transfer through metal. These heat exchangers work by having hot fluid pass through the inside of a coiled tube of metal. The fluid then makes contact with a colder fluid, and the two fluids turn into vapour and liquid. The vapour then rises and collects at the top of the tube, and the liquid flows down to the bottom of the tube. The process keeps repeating, and the heat generated from one fluid is transferred to another.
Thus, these are 3 useful types of heat exchangers that you will find in a plethora of industries. However, this list is by no means exhaustive as there are multiple variations of this device.
