Abstract

Interlock assembly 1 prevents disengagement of quick-release fluid coupling assemblies 2 and 3 in an undesired sequence. The desired sequence, release 3 only after first releasing 2, is established as a safety precaution. A cooling fluid circulating through inlet assembly 2, chamber 4, and outlet assembly 3 serves to cool a somewhat fragile integrated circuit device 5, the latter housed within the chamber, by direct contact with the device surface 6. When assemblies 2 and 3 are disengaged, valves are closed. Such action seals the chamber ducts and also seals off the inlet and outlet hoses 7 and 8 respectively supplying and withdrawing the fluid through the respective disengaged assemblies 2 and 3.

Interlock for Quick Release Fluid Couplings

Interlock assembly 1 prevents disengagement of quick-release fluid coupling assemblies 2 and 3 in an undesired sequence. The desired sequence, release 3 only after first releasing 2, is established as a safety precaution. A cooling fluid circulating through inlet assembly 2, chamber 4, and outlet assembly 3 serves to cool a somewhat fragile integrated circuit device 5, the latter housed within the chamber, by direct contact with the device surface 6. When assemblies 2 and 3 are disengaged, valves are closed. Such action seals the chamber ducts and also seals off the inlet and outlet hoses 7 and 8 respectively supplying and withdrawing the fluid through the respective disengaged assemblies 2 and 3. Consequently, disengagement of assembly 3 before disengagement of assembly 2 would trap coolant fluid under pressure in chamber 4 and transfer potentially harmful pressures through the fluid to device 5.

Quick-release couplings of the indicated type are particularly susceptible to disconnection in an arbitrary sequence while the fluid is under pressure because of the ease with which they are detached. The removable hose end sections 2' and 3' of the respective assemblies 2 and 3 are disengaged from respective mating section members 2'' and 3'', attached to the bulkhead wall 9 of chamber 4, by simply pulling the mated sections apart. Connections are made by inserting and turning sections 2' and 3' relative to the respective mat...
