Cooling arrangement for a server mountable in a server rack

A cooling arrangement for a server mountable in a server rack having a front side, a rear side, a bottom side, a top side, a first lateral side and a second lateral side opposite from the first lateral side, the cooling arrangement comprising:

• a phase change device, comprising:
• an evaporator adapted to be mounted on a heat-generating unit of the server,
• a condenser,
• a first conduit extending from the server to the first lateral side of the server rack, the first conduit being adapted to transport to the condenser a working fluid heated in the evaporator, and
• a second conduit extending from the server to the first lateral side of the server rack, the second conduit being adapted to return to the evaporator the working fluid cooled in the condenser;
• and
• a fluid cooling unit positioned along the first lateral side of the server rack, the fluid cooling unit comprising:
• a fluid inlet adapted to receive a cooling fluid from an external cooling facility,
• a fluid outlet adapted to return the cooling fluid to the external cooling facility, and
• a heat transfer module, comprising:
• an open channel parallel to the first lateral side of the server rack and adapted to slidably receive the condenser when the server is inserted in the server rack from a front side of the server rack, and
• a water jacket extending between the fluid inlet and the fluid outlet and surrounding at least in part the open channel,
• the heat transfer module being configured to allow a transfer of heat from the working fluid present in the evaporator to the cooling fluid present in the water jacket when the condenser is received in the open channel;
• the condenser having a H-shaped cross-section defined perpendicularly from a direction of insertion of the server in the server rack;
• the open channel having a C-shaped opening with top and bottom rails protruding within the C-shaped opening, the C-shaped opening and the top and bottom rails being adapted to mate with the H-shaped cross-section of the condenser when the condenser is received in the open channel.
