Kelaputkilämmönvaihtimet

Kelaputkilämmönvaihtimet, also known as coil tube heat exchangers, are devices designed to transfer thermal energy between two or more fluids. They are characterized by the use of coiled tubes, which significantly increase the surface area available for heat exchange within a given volume. This increased surface area enhances the efficiency of heat transfer compared to straight tube designs.

The basic principle of operation involves one fluid flowing through the coiled tubes while another fluid flows around the exterior of these tubes. The temperature difference between the two fluids drives the heat transfer process. The hot fluid will transfer its heat to the colder fluid, thereby altering the temperature of both. The coiled nature of the tubes allows for a longer path within the exchanger, maximizing contact time and thus the amount of heat transferred.

Kelaputkilämmönvaihtimet find application in various industrial and commercial settings. They are commonly used in HVAC systems for heating and cooling, in refrigeration cycles, in chemical processing, and in power generation. Their compact design and high thermal efficiency make them a suitable choice where space is limited or where significant heat transfer is required. Materials used in their construction are chosen based on the specific fluids being handled and the operating temperatures and pressures, with common choices including various metals like stainless steel or copper. The design can be adapted for different flow arrangements and capacities.
