In at least one embodiment, the tank can be exchanged with a larger tank to lower a liquid level in the header and/or a smaller tank to raise a liquid level in the header. In at least one embodiment, the pressure vessel can have an internal cross sectional area that decreases with elevation within the header. In at least one embodiment, the pressure vessel can have an internal conical post, which can have a larger lower diameter and a smaller higher diameter. In at least one embodiment, the pressure vessel can have an internal helix, which can have spacing that decreases with elevation within the header.

[0052] In at least one embodiment, a closed loop cooling system can include a heat exchanger that can transfer heat to a cooling media, a first condenser having a first inlet that can receive the media, a second condenser plumbed in parallel with the first condenser and having a second inlet that can receive the media, a header plumbed between the heat exchanger and the condensers, or any combination thereof. In at least one embodiment, the header can receive the media from the heat exchanger, retain a portion of the media therein in liquid form, selectively distribute the media to the condensers, or any combination thereof. In at least one embodiment, the header can have a header inlet fluidically coupled to the heat exchanger, a first outlet fluidically coupled to the first inlet, a second outlet fluidically coupled to the second inlet, or any combination thereof. In at least one embodiment, the first outlet can be located on the header at a lower elevation than the header inlet and/or the second outlet can be located on the header at a lower elevation than the first outlet.

[0053] In at least one embodiment, the header can selectively prevent vapor from exiting the second outlet, thereby selectively decreasing, or eliminating, the second condenser's capacity to remove heat from the media. In at least one embodiment, the header can prevent vapor from exiting the second outlet when the system is in a first cooling mode and allow vapor to exit the second outlet when the system is in a second cooling mode. In at least one embodiment, the second cooling mode can provide a higher cooling rate or capacity than the first cooling mode.

[0054] In at least one embodiment, the system can include a controller to control a cooling capacity, or rate, of the system by selectively covering the second outlet with the media in liquid form, thereby selectively preventing vapor from exiting the second outlet. In at least one embodiment, the controller can control a liquid level in the header by controlling a fan of the heat source and/or any of the condensers and/or controlling a prime mover, such as a pump or a compressor, plumbed between the condensers and the heat source, thereby controlling the cooling capacity, or rate, of the system.

[0055] In at least one embodiment, the header can be an angled pipe sloping downward from the first outlet to the second outlet. In at least one embodiment, the header can be a pipe having a first horizontal section, a second horizontal section, and an angled section between the first horizontal section and the second horizontal section. In at least one embodiment, the first outlet can be in the first horizontal section and/or the second outlet can be in the second horizontal section. In at least one embodiment, the second horizontal section can be located on the header at a lower elevation than the first horizontal section.

[0056] In at least one embodiment, the header can be a pressure vessel. In at least one embodiment, the pressure vessel can have a header inlet at a higher elevation than the first outlet. In at least one embodiment, the pressure vessel can have a liquid outlet at a lower elevation than the second outlet. In at least one embodiment, the liquid outlet can be located in a removable tank at a bottom of the pressure vessel. In at least one embodiment, the tank can be exchanged with a larger tank to lower a liquid level in the header and/or a smaller tank to raise a liquid level in the header. In at least one embodiment, the pressure vessel can have an internal cross sectional area that decreases with elevation within the header. In at least one embodiment, the pressure vessel can have an internal conical post, which can have a larger lower diameter and a smaller higher diameter. In at least one embodiment, the pressure vessel can have an internal helix, which can have spacing that decreases with elevation within the header.
