Abstract
A system for vacuum filling a cooling assembly is provided. The system comprising a manifold comprising a first aperture, a second aperture, and a third aperture. Further, an eductor fluidly coupled to the first aperture, a first valve fluidly coupled between the eductor and the first aperture, and an expansion reservoir sealingly coupled to the second aperture. An end unit is fluidly coupled to the third aperture, the end unit comprising a conduit fluidly coupled with the third aperture, a second valve fluidly coupled to the conduit, a cap for sealingly coupling with a supply volume, and a pipe coupled to the cap and fluidly coupled with the conduit, the pipe sealingly coupled to the cap and extending outwardly from the cap.

A system for vacuum filling a cooling assembly, the system comprising:
- a manifold comprising a first aperture, a second aperture, and a third aperture;
- an eductor fluidly coupled to the first aperture;
- a first valve fluidly coupled between the eductor and the first aperture;
- an expansion reservoir sealingly coupled to the second aperture;
- an end unit fluidly coupled to the third aperture, the end unit comprising:
- a conduit fluidly coupled with the third aperture;
- a second valve fluidly coupled to the conduit;
- a cap for sealingly coupling with a supply volume;
- and
- a pipe coupled to the cap and fluidly coupled with the conduit, the pipe sealingly coupled to the cap and extending outwardly from the cap.
A method of vacuum filling a cooling assembly with a system comprising a manifold comprising a first aperture, a second aperture, and a third aperture, an end unit fluidly coupled to the third aperture, a first valve fluidly coupled with the first aperture, a second valve fluidly coupled between the third aperture and the end unit, the end unit comprising a third valve, the method comprising:
- coupling the first aperture to a compressed air supply;
- fluidly coupling the second aperture to a cooling assembly;
- sealingly coupling the end unit to a coolant supply;
- opening the first valve to allow an air stream from the compressed air supply to flow through an air eductor, the pressure on the cooling assembly decreasing in response to the air flow flowing through the air eductor;
- closing the first valve subsequent to the pressure on the cooling assembly reaching a first predetermined threshold;
- opening each of the second valve and the third valve to allow coolant from the coolant supply to flow into the cooling assembly.
