lämmönvaihtimina

Lämmönvaihtimina, also known as heat exchangers, are devices designed to transfer heat between two or more fluids. They are widely used in various industries, including HVAC (heating, ventilation, and air conditioning), power generation, refrigeration, and chemical processing. Heat exchangers work on the principle of heat transfer, which can occur through conduction, convection, or radiation. The most common type of heat exchanger is the shell-and-tube heat exchanger, which consists of a series of tubes through which one fluid flows, surrounded by a shell through which another fluid flows. Other types include plate heat exchangers, which use a series of plates with channels for fluid flow, and air-cooled heat exchangers, which dissipate heat to the ambient air. Heat exchangers are crucial in maintaining efficient and safe operations in many industrial processes by facilitating the transfer of heat without mixing the fluids.
