What is a heat exchanger?

A heat exchanger is a device that transfers heat from a hot fluid to a cold fluid, also known as a heat exchanger. Its main function is to ensure the specific temperature required by the process for the medium.

It can be achieved between two or more fluids of different temperatures to transfer heat between the materials, so that the heat is transferred from the higher temperature fluid to the lower temperature fluid, so that the fluid temperature reaches the indicators specified in the process to meet the needs of the process conditions, while the heat exchanger is also one of the main equipment to improve energy utilization.

The role of heat exchanger

Heat exchanger is widely used, daily life heating with heating radiator, steam turbine devices in the condenser and aerospace rockets on the oil cooler, etc., are heat exchangers.

In the petroleum, chemical, light industry, pharmaceutical, energy and other industrial production, heat exchangers are often used as a low-temperature fluid heating or high-temperature fluid cooling, the liquid vaporization into steam or steam condensation into liquid.

Heat exchanger can be a unit of equipment, such as heaters, coolers and condensers, etc.; but also a process equipment components, such as ammonia synthesis tower heat exchanger. Heat exchanger is an important unit of chemical production equipment, according to statistics, the tonnage of the heat exchanger accounts for about 20% of the entire process equipment and some even up to 30%, its importance can be imagined
