nesteputkijäähdyttimet
Nesteputkijäähdyttimet, known in English as tube-in-tube heat exchangers or simply double pipe heat exchangers, are a basic type of heat exchanger. They consist of two concentric pipes, where one fluid flows through the inner pipe and another fluid flows through the annular space between the inner and outer pipes. Heat transfer occurs across the wall of the inner pipe. The direction of flow for the two fluids can be co-current (same direction) or counter-current (opposite directions). Counter-current flow is generally more efficient for heat transfer.
These heat exchangers are relatively simple in design and construction, making them cost-effective for certain applications.
Nesteputkijäähdyttimet find applications in various industries, including chemical processing, food and beverage production, and HVAC systems.
