Enclosure air conditioners remove the heat generated by electronic devices from the inside of cabinets or enclosures. They typically use refrigerants and include thermostatic controls to maintain programmed environmental conditions.
Heat exchangers are commonly used in a wide variety of industrial, chemical, and electronics processes to transfer energy and provide required heating or cooling.
Heat sinks are thermally conductive, usually metallic components or devices that absorb and dissipate heat generated by electronic components such as computers. Common heat sink materials include aluminum, copper, and steel.
