1. A fluid control device, comprising:
a plurality of pumps configured to convey a fluid; and
a housing at which a first pump of said plurality of pumps is installed, wherein
the housing includes:
a space in the housing,
a communication hole configured to communicate the space with the first pump,
a first coupling portion and a second coupling portion physically coupling to an external member,
a first opening in the first coupling portion and making the space open to an outside,
a second opening in the second coupling portion and making the space open to the outside, and
the first coupling portion and the second coupling portion have outer shapes that may be fit to each other such that when the housing is coupled to another housing, the two housings communicate with each other through the first opening of the housing and the second opening of the other housing,
wherein said housing includes a plurality of walls that collectively define said space, wherein said communication hole is formed in a first wall of said plurality of walls, and wherein said first pump is disposed outside of said space and overlays an external surface of said first wall.
