A coil heat exchanger is a type of heat exchanger that uses a coiled design for heat exchange. It consists of a single or multiple tubes arranged in a coil shape, allowing for efficient heat transfer in a compact design. One fluid flows through the tubes, while another fluid flows around or within the coil, transferring heat between them.
Key Features and Advantages:
Compact Design:
The coiled design allows for efficient heat transfer in a small space, making it suitable for applications where space is limited.
High Heat Transfer:
The serpentine path of the fluid through the coil provides a longer travel distance, maximizing heat transfer.
Versatile Applications:
Coil heat exchangers can be used in various industries, including chemical, petrochemical, refrigeration, and food processing.
Enhanced Heat Transfer:
The use of fins or other enhancements on the outside of the coil can further improve heat transfer efficiency.
Separate Air Flows:
In certain applications, like hospital ventilation or industrial environments, coil heat exchangers can provide completely separate air flows, ensuring hygiene and preventing odor transfer, according to Swegon.
