Abstract
Embodiments of the invention provide a system and method for providing parallel flow paths for a high density liquid cooling system. The system includes a coolant distribution unit including primary loop piping and secondary loop piping. The secondary loop piping includes a first flow path including a first pump, a first filter, and a first shutoff valve. The secondary loop piping includes a second flow path including a second pump, a second filter, and a second shutoff valve. The system includes an inlet y-pipe upstream of both of the first flow path and the second flow path and an outlet y-pipe downstream of both of the first flow path and the second flow path. Each of the first and second shutoff valves alternate between an open position and a closed position.
Claims20
A system for providing parallel flow paths for a high density liquid cooling system, the system comprising:
- a coolant distribution unit including primary loop piping and secondary loop piping, the secondary loop piping including:
- a first flow path including a first pump, a first filter, and a first shutoff valve;
- a second flow path including a second pump, a second filter, and a second shutoff valve;
- an inlet y-pipe upstream of both of the first flow path and the second flow path;
- and
- an outlet y-pipe downstream of both of the first flow path and the second flow path,
- each of the first and second shutoff valves being alternatable between an open position and a closed position,
- when the shutoff valve of one of the first flow path and the second flow path is in the closed position, flow is not allowed through the one of the first flow path and the second flow path.
A system for providing redundant flow paths for flow through a secondary coolant loop of a coolant distribution unit, the system including:
- a first flow path;
- a second flow path;
- a first pump configured to induce flow through the first flow path;
- a second pump configured to induce flow through the second flow path;
- a first filter downstream of the first pump;
- a second filter downstream of the second pump;
- and
- an outlet y-pipe configured to combine flow from the first flow path and the second flow path, the outlet y-pipe having a first branch in fluid communication with the first flow path and a second branch in fluid communication with the second flow.
A method of operating parallel flow paths of a secondary loop for a coolant distribution unit, the method including:
- providing a first flow path including a first pump, a first valve, and a first filter;
- providing a second flow path including a second pump, a second valve, and a second filter;
- providing an inlet y-pipe including a first branch in fluid communication with the first flow path and a second branch in fluid communication with the second flow path;
- opening the first valve to allow fluid flow through the first flow path;
- delivering, from the first branch, coolant to the first flow path;
- operating the first pump to induce fluid flow through the first flow path.
