Abstract: Disclosed is a liquid cooling module for computer servers, including: a pump, a fan, a heat exchanger, at least two ventilation grilles, an open central longitudinal space between the pump and the heat exchanger that is arranged to facilitate airflow therein from a grille of one short side wall to a grille of the other short side wall, this airflow being driven by the fan, a portion of secondary hydraulic circuit located in the liquid cooling module, for circulating a fluid coolant, including no bypass that would allow the pump to operate as a closed circuit and likely to clutter this open longitudinal space, a circuit control board positioned in the longitudinal extension of the open central longitudinal space so as to be directly swept by the airflow.

Abstract: Disclosed is a method of communication between a plurality of liquid cooling modules of a cooling system for one or more one computer servers, in which: the cooling modules communicate with each other in a manner that operates in N+1 redundancy where N is greater than or equal to 2, so as to enable a standard replacement of any one of these cooling modules without stopping the cooling and without stopping the operation of the server or servers, this communication being ensured by a collaborative protocol without master/slave, before switching from an active mode where it is cooling to a backup mode where it is no longer cooling, the redundant cooling module verifying beforehand that a data set is consistent across all these cooling modules and that this consistency is maintained for a predetermined duration.

Abstract: Disclosed is a computer cabinet including: at least one computer server, and at least one module for the liquid cooling of the server. The cabinet includes at least three liquid cooling modules that communicate with each other using a collaborative protocol without master/slave technology, in such a way as to operate under N+1 redundancy where N is higher than or equal to 2, so as to be able to carry out a standard replacement of any one of the cooling modules without stopping the cooling of the computer cabinet and without stopping the operation of the server located in the computer cabinet, each of the liquid cooling modules including their own system for regulating the cooling and detecting failure.
