3-way quick-disconnect fluid couplings with automatic bypass switching

An information processing device comprising:

• a chassis;
• a primary space in the chassis and one or more primary electronic components disposed in the primary space;
• a primary liquid cooling loop disposed in the primary space and configured to circulate liquid coolant to cool the one or more primary electronic components, the primary liquid cooling loop comprising a supply portion, a return portion, and a bypass path connecting the supply portion to the return portion, the bypass path comprising one or more bypass portions connected in series;
• one or more expansion spaces in the chassis, each expansion space configured to receive a corresponding expansion device and a corresponding expansion loop to cool the expansion device;
• and
• one or more fluid coupling pairs connected to the primary liquid cooling loop and corresponding, respectively, to the one or more expansion spaces, each fluid coupling pair comprising two 3-way fluid couplings;
• wherein, for each of the fluid coupling pairs:
• the 3-way fluid couplings are configured to automatically switch between an expansion-present state and an expansion-absent state based on whether an expansion loop is installed in the corresponding expansion space and complementary fluid couplings of the expansion loop are mated with the 3-way fluid couplings;
• in the expansion-absent state, the 3-way fluid couplings direct liquid coolant to flow through a corresponding one of the bypass portions which extends between the 3-way fluid couplings;
• and
• in the expansion-present state, the 3-way fluid couplings direct liquid coolant to flow through the expansion loop and block the corresponding bypass portion.
