Cooling Method for Computer System

摘要

A computer system (taking server as an example) is cooled by using liquid coolants such as water, oil, and ionic liquid. Liquid coolant flows in a closed coolant conduit which is configured thermally to contact heat-generating components and a liquid-liquid heat exchanger. The heat generated in computer chips is carried out by liquid coolant and dissipated to heat exchanger where cooling water dissipates heat to large water body. For economic stable operation, cooling water is pumped from large water body such as river to a water tower where water level kept constant to ensure heat exchanger work at optimal condition. The simple and effective approach for computer system cooling provided in this disclosure is a cost-effective data center efficiency solution.

1. A cooling system for a plural of heat-generating components in a computer system, comprising
a. One or plural of heat-exchanging channels configured to be placed in thermal contact with said heat-generating components; b. A liquid-liquid heat exchanger including a first exchanger conduit and a second exchanger conduit wherein a first liquid coolant flows in said first exchanger conduit and a cooling water flows in said second exchanger conduit; heat is dissipated from said first liquid coolant in said first exchanger conduit to said cooling water in said second exchanger conduit; c. A closed conduit including a supply conduit, said heat-exchanging channels, a return conduit, and said first exchanger conduit of said liquid-liquid heat-exchanger; wherein said first liquid coolant is configured to be circulated in said closed conduit; said supply conduit is configured to flow said first liquid coolant into said heat-exchanging channels, a return conduit is configured to flow said first liquid coolant out of said heat-exchanging channels; said supply conduit and said return conduit have larger cross-sectional areas for flowing of said first liquid coolant than sum of cross-sectional areas of said heat-exchanging channels; d. A first pump configured to drive circulating of said first liquid coolant in said closed conduit; e. A water tower configured to have an elevated water level higher than the elevation of a large water body; wherein a second pump is configured to pump said cooling water from said large water body into said water tower; a drain outlet is configured at a lower elevation than said elevated water level to flow said cooling water out of said water tower; f. A cooling conduit configured to connect said drain outlet to a first end of said second conduit of said liquid-liquid heat exchanger to flow said cooling water from said water tower into said liquid-liquid heat exchanger; g. A back conduit configured to connect a second end of said second conduit of said liquid-liquid heat exchanger to said large water body to flow said cooling water from said liquid-liquid heat exchanger to said large water body;
