Liquid cooling arrangement for datacenter server rack

A liquid cooling arrangement for cooling heat-generating components of a datacenter server rack, comprising:

• a liquid cooling loop configured to convey a cooling liquid;
• a plurality of server clusters, each server cluster including a plurality of server assemblies that incorporate at least one respective liquid cooling unit configured to collect at least a portion of a thermal energy generated by a heat-generating component of the server assembly;
• at least one heat exchanger fluidly connected to the liquid cooling units of the plurality of server clusters via the liquid cooling loop, the heat exchanger comprising at least one manifold for collecting the cooling liquid and a zone, called thermal exchanges zone, the heat exchanger being configured such that thermal energy is exchanged between the liquid and an air flow in the thermal exchanges zone;
• and
• a pump fluidly coupled to the heat exchanger via the liquid cooling loop, the pump configured to convey the cooling liquid in the liquid cooling loop,
• wherein the liquid cooling arrangement comprises at least one element, called vibrations element, configured to generate a field of vibrations of the cooling liquid in an area of said at least one exchanger, called vibrations area.
