Fluid-cooled electrical equipment, avionic rack to receive such equipment and aircraft equipped with such racks

摘要

This invention relates to a fluid-cooled electronic equipment item, an avionic rack to receive such an equipment item and an aircraft equipped with such racks.;The electronic equipment items are connected to the avionic rack on the one hand electrically (C3-C4) and on the other hand fluidically (36′-37, 45′-44) to a system of pipes (30a, 30b) on at least one cold source for a cooling fluid (30). A heat-dissipating electronic board (35) is equipped with a dissipated-heat collector plate (61-65), in which fluid circulation channels are implemented, connected via quick-disconnect fluidic couplings (42, 39) to quick-disconnect fluidic couplings of the system of pipes. These devices allow the equipment to be removed from or inserted into the rack (32-EE) or the electronic board (35) to be removed from or inserted into the electrical equipment (33-35).

主权项

1. Electronic equipment including a packaging and containing at least one heat-dissipating electronic board connected electrically to a sub-rack bottom assembly, comprising:
at least one crosspiece integral with the sub-rack bottom assembly including a first set of quick-disconnect fluidic couplings for coupling to a cooling fluid system outside the equipment, wherein the first set of quick-disconnect fluidic couplings is accessible from outside the packaging, wherein the at least one electronic board is equipped with at least one metal heat collector plate, the plate including at least one groove forming at least one channel with the at least one electronic board to guide cooling fluid to warm zones of the at least one electronic board, the at least one channel being fluidcally coupled with the first set of quick-disconnect fluidic couplings for intake and outtake of the cooling fluid, wherein the at least one crosspiece includes a second set of quick-disconnect fluidic couplings, and wherein the at least one electronic board includes a set of quick-disconnect fluidic couplings to connect to the second set of quick-disconnect fluidic couplings integral with the at least one crosspiece, the at least one crosspiece including a distribution chamber for conveying the cooling fluid between the first set of quick-disconnect fluidic couplings and the second set of quick-disconnect fluidic couplings.
