The tank includes a base and at least one sidewall. The base is connected to the sidewall. The condenser is located within the tank. The condenser is adapted to transform vapor into liquid. The cross-flow fan is near the condenser. The cross-flow fan produces an airflow. The internal wall system is located adjacent to the cross-flow fan to assist in directing the airflow from the cross-flow fan. The top cover is located generally opposite to the base. The sloping wall is located between the top cover and the sidewall. The sloping wall provides a closed airflow loop for the airflow produced by the cross-flow fan. ## Claims ### Claim 1 An immersion liquid cooling tank assembly comprising: a tank including a base and at least one sidewall, the base connected to the at least one sidewall; a condenser located within the tank, the condenser adapted to transform vapor into liquid; at least one cross-flow fan near the condenser, the at least one cross-flow fan producing an airflow; an internal wall system located adjacent to the at least one cross-flow fan to assist in directing the airflow from the cross-flow fan; a top cover located opposite to the base; and at least one sloping wall located between the top cover and the least one sidewall, the at least one sloping wall providing a closed airflow loop for the airflow produced by the at least one cross-flow fan, wherein the at least one cross-flow fan is located near the top cover and the condenser is located near the top cover, the condenser being configured to receive the airflow from the closed airflow loop. ### Claim 2 (depends on 1) The assembly of claim 1, wherein the at least one sidewall is a plurality of sidewalls. ### Claim 3 (depends on 1) The assembly of claim 1, wherein the at least one cross-flow fan is a plurality of cross-flow fans. ### Claim 4 (depends on 3) The assembly of claim 3, further including a partition located between the plurality of cross-flow fans. ### Claim 5 (depends on 1) The assembly of claim 1, wherein the internal wall system includes a plurality of walls. ### Claim 6 (depends on 1) The assembly of claim 1 further including a coolant located and contained within the tank. ### Claim 7 (depends on 6) The assembly of claim 6, wherein the coolant is a fluorocarbon. ### Claim 8 (depends on 6) The assembly of claim 6, wherein the coolant is water or a mixture including water. ### Claim 9 (depends on 1) The assembly of claim 1 further including a plurality of heat-generating components contained within the tank. ### Claim 10 (depends on 9) The assembly of claim 9, wherein the plurality of heat-generating components includes storage servers, application servers, switches, or other electronic devices. ### Claim 11 (depends on 1) The assembly of claim 1, wherein the at least one sloping wall slopes inwardly at an angle of from 10 to 80 degrees as measured from the base, the at least one sidewall being a plurality of sidewalls, the at least one sloping wall being located between two of the plurality of sidewalls. ### Claim 12 (depends on 11) The assembly of claim 11, wherein the at least one sloping wall slopes inwardly at an angle of from 20 to 70 degrees as measured from the base, the at least one sidewall being a plurality of sidewalls, the at least one sloping wall being located between two of the plurality of sidewalls. ### Claim 13 An immersion liquid cooling tank assembly comprising: a tank including a base and at least one sidewall, the base connected to the at least one sidewall, the base being generally perpendicular to the at least one sidewall; a condenser located within the tank; at least one cross-flow fan; an internal wall system located adjacent to the at least one cross-flow fan to assist in directing the airflow from the at least one cross-flow fan; a top cover located opposite to the base; at least one sloping wall connecting the top cover and the least one sidewall, the at least one sloping wall being generally diagonal relative to the top cover and the at least one sidewall; a coolant contained within the tank; and a plurality of heat-generating components contained within the tank, wherein the at least one cross-flow fan is located near the top cover and the condenser is located near the top cover, the condenser being configured to receive the airflow from a closed airflow loop for the airflow that is produced by the at least one cross-flow fan. ### Claim 14 (depends on 13) The assembly of claim 13, wherein the coolant is a fluorocarbon. ### Claim 15 (depends on 13) The assembly of claim 13, wherein the coolant is water or a mixture including water. ### Claim 16 (depends on 13) The assembly of claim 13, wherein the plurality of heat-generating components includes one or more of: storage servers, application servers, switches, and other electronic devices. ### Claim 17 (depends on 13) The assembly of claim 13, wherein the at least one sloping wall slopes inwardly at an angle of from 10 to 80 degrees as measured from the base, the at least one sidewall being a plurality of sidewalls, the at least one sloping wall being located between two of the plurality of sidewalls. ### Claim 18 (depends on 17) The assembly of claim 17, wherein the at least one sloping wall slopes inwardly at an angle of from 20 to 70 degrees as measured from the base, the at least one sidewall being a plurality of sidewalls, the at least one sloping wall being located between two of the plurality of sidewalls. ### Claim 19 (depends on 13) The assembly of claim 13, wherein the internal wall system includes a plurality of walls.
