1. A cooling system for immersed computing devices, comprising:
a cooling bath tank that contains a cooling fluid that flows through an inside thereof from at least one outlet to a first at least one inlet, in which said cooling bath tank is designed and arranged to enable at least a first portion of at least one computing device to be cooled to be inserted therein, said computing device being at least partially immersed in the cooling fluid contained therein, and
at least one cooling unit designed to collect and cool the cooling fluid flowing out of said at least one inlet and to return the cooling fluid, once cooled, through said at least one outlet into said cooling bath tank, the at least one cooling unit designed to be inserted into said cooling bath tank, to be at least partially immersed in the cooling fluid contained therein, and to be removed therefrom, and including a casing with projections designed and arranged to be supported at least by supports projecting inwards from internal walls of the cooling bath tank when the cooling unit is inserted into the cooling bath tank, the casing having a first compartment fluidly connected with the at least one outlet and a second compartment housing a heat exchanger that are fluidly isolated from one another, said first compartment having a second inlet to enable the cooling fluid coming out of the at least one outlet in the cooling bath tank to enter said first compartment,
wherein said first compartment has a first sub-compartment and a second sub-compartment fluidly connected with the at least one outlet, in which said first sub-compartment at least partially houses a fluid pump comprising a suction inlet therein that is immersed in the cooling fluid that has entered through said second inlet of the first compartment and that is designed and arranged to pump said cooling fluid to a third inlet of a first circuit of the heat exchanger that is housed in said second compartment and designed to cool fluid flowing through said first circuit by means of a refrigerant fluid that is flowing through a second circuit of the heat exchanger, enabling the cooled down cooling fluid flowing through said first circuit of said heat exchanger to flow to the second sub-compartment through a cooling-fluid outlet arranged therein.
