| 摘要 |
The present invention relates to an arrangement (100) and a method in a radio network node (400) for cooling electronic equipment (102) within the arrangement (100). The arrangement (100) comprises a closed space (104) for housing the electronic equipment (102) and a heat exchanger (106) for transporting heat from the closed space. A first flow regulating device (202) is arranged for circulating a cooling fluid (204) within the closed space (104) and a second flow regulating device (206) is arranged for circulating an outer cooling fluid (208) outside (112) the closed space. The arrangement (100) further comprises at least one sensor (301, 302, 303, 304, 305, 306) for measuring temperature in the arrangement and a controller (210) for controlling at least one of the first and second flow regulating devices (202, 206) based on at least one temperature measurement from a fixed member (102, 104, 106, 112, 308) within the arrangement (100).
