levylämmönvaihdin

Levylämmönvaihdin, also known as a plate heat exchanger, is a type of heat exchanger that utilizes metal plates to transfer heat between two fluids. These plates are typically made of corrugated stainless steel, which increases their surface area and turbulence, thereby enhancing heat transfer efficiency. The fluids flow through alternating channels formed by the plates, allowing heat to pass from the hotter fluid to the colder fluid without the two fluids mixing.

The design of a levylämmönvaihdin allows for a compact and efficient solution for heating or cooling applications. They are often used in industrial processes, HVAC systems, and refrigeration. Their modular design means that the heat transfer capacity can be adjusted by adding or removing plates. Maintenance is generally straightforward, as the plates can be disassembled for cleaning or replacement.

Compared to shell-and-tube heat exchangers, levylämmönvaihtimet typically offer higher thermal efficiency and require less space. However, they can be more susceptible to clogging if the fluids contain particulate matter. The materials used for the plates can be selected to suit the corrosive properties of the fluids being handled. Common applications include central heating systems, food and beverage processing, and chemical industries.
