LIQUID COOLING SYSTEM AND METHOD FOR COOLING AT LEAST ONE RADIO UNIT

摘要

The invention relates to a liquid cooling system (2) for cooling at least one radio unit (4, 6) using liquid (8), where the liquid cooling system (2) comprises a cooling unit (10) arranged to cool the liquid (8) and further comprises a liquid loop (12) in which the liquid (8) is arranged to be conveyed from a supply outlet (14) of the cooling unit (10) to the at least one radio unit (4, 6) where the liquid (8) is arranged to cool the at least one radio unit (4, 6) before being conveyed back in the liquid loop (12) to a return inlet (16) of the cooling unit (10), the cooling unit (10) being arranged located at a distance from the at least one radio unit (4, 6), wherein the cooling unit (10) is an expandable cooling unit comprising a secondary outlet (20) and a secondary inlet (22) where, when an additional cooling unit (24) of the liquid cooling system (2) is connected with an inlet (26) to said secondary outlet (20) and with an outlet (28) to said secondary inlet (22), the liquid (8) is arranged to be fed from the cooling unit (10) through the secondary outlet (20) to the additional cooling unit (24) arranged to also cool the liquid (8) and thereafter fed back to the cooling unit (10) through the secondary inlet (22). The invention also relates to a method for cooling at least one radio unit (4, 6).
