Soojusvahetitelid, also known as heat exchangers, are devices designed to transfer heat between two or more fluids. They are commonly used in various industries, including HVAC, automotive, and power generation, to improve energy efficiency and reduce operational costs. Heat exchangers work on the principle of heat transfer, where heat is transferred from a hot fluid to a cold fluid without direct mixing of the fluids. This is achieved through a barrier, such as a metal wall, that separates the fluids but allows heat to pass through.

There are several types of heat exchangers, each with its own design and application. Shell and tube heat exchangers are one of the most common types, consisting of a series of tubes through which one fluid flows, surrounded by a shell through which another fluid flows. Plate heat exchangers, on the other hand, use a series of plates with alternating channels for the two fluids, allowing for a larger heat transfer surface area in a smaller footprint. Another type is the air-cooled heat exchanger, which uses air to cool a hot fluid, often found in industrial and automotive applications.

Heat exchangers are crucial in many processes, such as cooling engines in vehicles, heating and cooling buildings in HVAC systems, and generating steam in power plants. They play a vital role in optimizing energy use and reducing environmental impact by minimizing heat loss and maximizing heat transfer efficiency. The design and selection of a heat exchanger depend on factors such as the type of fluids involved, the required heat transfer rate, and the available space for installation.
