Perhaps the simplest type of heat exchanger, the tube-fin effectively cools a variety of automotive systems. The concept is simple: Fluid cools as it travels through the core by transferring heat out to the fins. The fins then provide the surface area necessary for sufficient heat exchange to take place, allowing the heat pulled from the fluid to dissipate into the surrounding air. Quick, easy and effective.
Take it a step further with a fan-mounted unit and you can be sure that there will always be optimum airflow for your tube-fin cooler no matter where it is mounted or what sort of environment you are traveling through, making it perfect for those hot days spent sitting in traffic.
