Server cooling system without the use of vapor compression refrigeration
View Patent ↗A system, method, and computer product for cooling a server center without the use of vapor compression refrigeration. An example embodiment involves using outdoor ambient air to cool first server components directly and to cool heat exchanges containing liquid used to cool second server components.
1. A method for cooling a server center comprising:
forming an air cooling path to cool first server components by convection to outdoor ambient air by passing the outdoor ambient air over the first server components;
circulating a liquid coolant to cool second server components through direct thermal conduction into the liquid coolant, the liquid coolant is cooled by flowing the outdoor ambient air over a heat exchanger without the use of a vapor compression refrigeration unit;
passing the outdoor ambient air into an entrance of the server center through openings on a plurality of sidewalls, each sidewall including a first side exposed to the outdoor ambient air and second side facing the first server components and the second server components;
passing heated air out of the server center through at least one chimney; and
channeling the outdoor ambient air entering above a raised floor to the heat exchangers and channeling the outdoor ambient air entering below the raised floor to the first server components.
2. The method of claim 1 , further comprising controlling airflow through the openings in the server center sidewalls using at least one of air filters and louvers.
3. The method of claim 1 , further comprising controlling flow of the liquid through different heat exchangers using valves.
4. A computer program product for cooling a server center, the computer program product comprising:
a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to:
form an air cooling path to cool first server components by convection to outdoor ambient air by passing outdoor ambient air over the first server components; and
circulate a liquid coolant to cool second server components through direct thermal conduction into the liquid coolant, the liquid coolant is cooled by flowing the outdoor ambient air over a heat exchanger without the use of a vapor compression refrigeration unit;
pass the outdoor ambient air into an entrance of the server center through openings on a plurality of sidewalls, each sidewall including a first side exposed to the outdoor ambient air and second side facing the first server components and the second server components;
pass heated air out of the server center through at least one chimney; and
channel the outdoor ambient air entering above a raised floor to the heat exchangers and channeling the outdoor ambient air entering below the raised floor to the first server components.
5. The computer program product of claim 4 , further comprising computer readable program code to control airflow through openings in the server center sidewalls using at least one of filters and louvers.
6. The computer program product of claim 4 , further comprising computer readable program code to control flow of the liquid coolant through different heat exchangers using valves.
