Abstract

Embodiments of the invention provide a liquid fill kit system including a rollable cart having a frame and a plurality of wheels. A tank disposed within the frame. The fill kit further includes a fluid pump including a suction interface connection and a discharge interface connection. A filter assembly mounted within the frame. A fluid pressure regulator include a fluid outlet port, the fluid pressure regulator being configured to stop a flow of fluid when a pressure exceeds a fluid pressure threshold. In a first configuration, the suction interface connection is in fluid communication with the tank, and the discharge interface connection is in fluid communication with the filter unit, the pressure regulator, and the fluid outlet port to generate a flow of fluid through the fluid outlet port.

First claim

The invention claimed is:

1 . A liquid fill kit system comprising:
a rollable cart including a frame and a plurality of wheels; a tank disposed within the frame, the tank including a fluid inlet port that is selectively fluidly connected to a fluid outlet port of an electrical component; a fluid pump including a suction interface connection and a discharge interface connection; a filter assembly mounted within the frame; and a fluid pressure regulator including a fluid outlet port that is selectively fluidly connected to a fluid inlet port of the electrical component and a valve that stops a flow of fluid from the tank to the fluid inlet port of the electrical component when a fluid pressure exceeds a fluid pressure threshold; wherein, in a first configuration, the suction interface connection is in fluid communication with the tank, and the discharge interface connection is in fluid communication with the filter assembly, the fluid pressure regulator, and the fluid outlet port, and wherein, when the fluid pump is in operation and the fluid pressure is below the fluid pressure threshold, the flow of fluid is generated through the fluid outlet port.

2 . The liquid fill kit system of claim 1 , wherein the fluid pressure regulator includes a manual control, wherein a position of the manual control determines the fluid pressure threshold.

3 . The liquid fill kit system of claim 1 , further comprising an air compressor mounted within the frame.

4 . The liquid fill kit system of claim 1 , wherein the suction interface connection and the discharge interface connection are quick disconnect fittings.

5 . The liquid fill kit system of claim 1 , where, in a second configuration, the suction interface connection is in fluid communication with a fluid reservoir and the discharge interface connection is in fluid communication with the tank.

6 . The liquid fill kit system of claim 1 , wherein the tank includes a tank outlet, and wherein a drain valve is disposed downstream of the tank outlet.

7 . The liquid fill kit system of claim 2 , wherein the manual control includes a pressure regulation knob.

8 . The liquid fill kit system of claim 1 , wherein the fluid pressure regulator includes a gauge display that displays the fluid pressure flowing past the valve.

9 . The liquid fill kit system of claim 1 , further comprising a switch that selectively provides power to the fluid pump.

10 . The liquid fill kit system of claim 1 , wherein a volume of the tank is between about 20 gallons and about 60 gallons.

11 . A method of charging an electrical component with a fluid coolant, the method comprising:
providing a fill kit including a rollable frame, a fluid inlet hose, a fluid outlet hose, a tank disposed within the rollable frame, a pump, and a pressure regulator, the pressure regulator including a manual control and a valve, each of the tank, the pump, and the pressure regulator being fluidly between the fluid inlet hose and the fluid outlet hose; providing an electrical component having a fluid inlet port and a fluid outlet port; setting, at the pressure regulator via the manual control, a pressure threshold; fluidly connecting the fluid inlet hose to the fluid outlet port; fluidly connecting the fluid outlet hose to the fluid inlet port; inducing, by the pump, a flow of fluid from the tank to the fluid inlet port through the fluid inlet hose; and when a fluid pressure meets or exceeds the pressure threshold, closing the valve, wherein closing the valve stops the flow of fluid from the tank to the fluid inlet port.

12 . The method of claim 11 , wherein the manual control comprises a rotatable knob.

13 . The method of claim 11 , wherein both of the fluid inlet hose and the fluid outlet hose comprise quick-disconnect fittings.

14 . The method of claim 11 , further comprising filling the tank, wherein filling the tank includes inducing, by the pump, a flow of fluid from a reservoir to the tank.

15 . The method of claim 11 , wherein the fluid inlet hose includes a sight glass.

16 . A liquid fill kit system comprising:
a rollable cart including a frame and a plurality of wheels; a tank disposed within the frame; a fluid outlet; the tank including a fluid inlet that is slectively fluidly connected to a fluid outlet port of an electrical component; a fluid pump including a suction interface connection and a discharge interface connection; and a fluid pressure regulator including a valve that closes in response to a fluid pressure exceeding a fluid pressure threshold; wherein, in a first configuration, the suction interface connection is fluidly downstream of the tank, and the discharge interface connection is fluidly upstream of the fluid pressure regulator and the fluid outlet, wherein, when the fluid pressure is below the fluid pressure threshold, a liquid coolant flows between the tank and the fluid outlet to provide the liquid coolant to the electrical component, and wherein when the fluid pressure meets or exceeds the fluid pressure threshold, the flow of the liquid coolant is stopped between the tank and the fluid outlet.

17 . The liquid fill kit system of claim 16 , wherein the fluid pressure regulator includes a manual control wherein the fluid pressure threshold is determined by a position of the manual control.

18 . The liquid fill kit system of claim 16 , further including a return hose in fluid communication with the tank, the return hose including a sight glass.

19 . The liquid fill kit system of claim 16 , further comprising a filter fluidly upstream of the fluid pressure regulator.

20 . The liquid fill kit system of claim 16 , wherein the electrical component is one or more of:
a pumping unit; a heat exchanger; a coolant distribution unit; a server shelf; or a manifold.
