Abstract: A plurality of cooling units for cooling electrical components can be disposed in close proximity to one another in confined spaces with minimal space conflict, due to the design of the cooling units that allows for staggered position of connection fittings. Also, the cooling units can be selectively arranged in a plurality of configurations with respect to one another, while being fluidly connected.

Abstract: A conduit coupling can have a male portion and a female portion, with each portion having an internal biasing member. The internal biasing members can cause a seal within each of the portions to be biased against an internal wall to seal liquid from leaking out of the portions when they are disconnected. The conduit coupling can also have an absorbing member for absorbing residual fluid when the portions are disconnected.
