The present invention is directed to a thermosyphon heat exchanger. The thermosyphon system eliminates the need for costly and inefficient moving parts in the cooling system. The system also minimizes failures rendering the system inoperable by eliminating mechanical components subject to breakdowns that would render the system inoperable. The design of the heat exchanger coils provides for increased efficiency, reduced cost, and simplified construction and maintenance. The system further reduces the energy consumption required for cooling operation while still providing excellent cooling performance.
