Cooling system for telecommunications equipment arranged in a cabinet or similar

A cooling system for telecommunications equipment, comprising:

• a first space;
• a first telecommunications device located in said first space that generates a first heat amount when operating;
• a hermetically sealed second space;
• a second telecommunications device located in said hermetically sealed second space that generates a second heat amount when operating that is less than the first heat amount;
• a gas located in said hermetically sealed second space;
• an inlet into said first space communicating said first space with ambient air;
• an outlet out of said first space communicating said first space with ambient air, said inlet and outlet for circulating ambient air through said first space to cool said first telecommunications device;
• a heat exchanger in communication with ambient air that circulates through said first space;
• and
• a gas circulation conduit for circulating the gas in said hermetically sealed second space through said heat exchanger to cool said second telecommunications device.

A cooling system for telecommunication equipment, comprising:

• a cabinet having a first space and a hermetically sealed second space;
• at least one hermetically sealed box located in said first space;
• a telecommunications device of a first heat generating capacity located in said first space;
• a telecommunications device of a second heat generating capacity less than said first heat generating capacity located in said hermetically sealed second space;
• means for circulating ambient air through said first space to cool said telecommunications device located in said first space;
• and
• means for cooling a gas in said hermetically sealed space with ambient air circulating through said first space.
